PRIMARY CONFIGURATION

Top-Running Overhead Crane

ALTERNATIVE SUPPORT

Underhung or Gantry

HOIST OPTIONS

Wire Rope, Chain & Low Headroom

CONTROL OPTIONS

Pendant, Radio, Cabin & PLC

The crane structure, hoist, end carriages, power distribution and controls form one coordinated load-handling system. The main girder transfers the suspended load and bridge self-weight into the end carriages. Wheels transfer vertical and horizontal reactions through the rails into the runway or gantry legs. The selected hoist controls lifting performance and much of the hook approach.

A purchase specification should identify every interface. Bridge steel and lifting machinery do not automatically include runway beams, rails, support columns, foundations, incoming plant power, installation, test weights or local statutory inspection. Defining these boundaries before quotation prevents equipment-only prices from being compared with complete installed systems.

01 · Main Girder

A rolled section, composite beam or welded box girder carries the moving hoist and transfers load into the end carriages. Span, capacity, deflection, fatigue and hoist-wheel loading establish the design.

02 · Electric Hoist

The lifting unit includes motor, brake, gearbox, drum or load chain, rope or chain guide, hook block and limits. Capacity, lift, reeving, speed and duty must match the handling cycle.

03 · End Carriages

Wheel assemblies support the bridge and provide longitudinal travel. Wheel diameter, spacing, rail profile, drives and guide arrangement are coordinated with runway geometry and reactions.

04 · Electrification

Conductor bars or festoon systems supply the bridge, while a festoon, cable track or energy chain supplies the moving hoist. Voltage, travel length and environment determine the arrangement.

05 · Controls and Protection

Pendant, radio, cabin or PLC controls operate the motions with emergency stop, brakes, upper and lower limits, overload protection and project-specific alarms or interlocks.

06 · Runway Interface

Rails, beams, brackets, columns and foundations receive crane forces. New and existing structures require approved wheel loads, side thrust, alignment tolerance and end-stop design.

Top-Running Single-Girder Overhead Crane

Bridge wheels travel on rails above the runway beams, while the electric hoist normally runs beneath the girder. This is the principal configuration for production workshops, warehouses, fabrication bays and maintenance facilities.

Underhung Single-Girder Crane

Bridge end carriages travel on the lower flanges of suspended runway beams. The arrangement can improve floor utilization and end approach, but roof beams, hangers, connections and runway flanges must be verified for crane reactions.

Low-Headroom Electric-Hoist Crane

A compact or offset hoist arrangement reduces the vertical distance between runway level and upper hook position. It is developed for low roofs or existing buildings where usable hook height has direct production value.

Single-Girder Gantry Crane

Travelling legs support the bridge on ground rails. This configuration serves yards, workshops without elevated runway steel and production zones where building loads should remain independent.

Intelligent Single-Girder Crane

Variable-frequency drives, load monitoring, anti-sway, positioning, diagnostic functions and PLC communication can be integrated where motion quality, process repeatability or production data are required.

Special-Environment Single-Girder Crane

Explosion-proof, cleanroom, insulated, corrosion-resistant or metallurgical electric-hoist variants require environment-specific equipment, materials, enclosures and protective logic defined by the operating hazard.

01 · Gross Suspended Load

Include payload, lifting beam, slings, clamps, magnets, grabs and every below-hook component. State maximum, normal and future loads rather than nominal product weight alone.

02 · Span and Travel Length

Span is normally the runway rail centreline distance. Runway length determines longitudinal coverage, electrification length and installation quantities.

03 · Lift and Headroom

Provide lowest pickup, highest placement, rail elevation, roof clearance, load height and rigging depth. Required hook height must be checked on a dimensioned arrangement.

04 · Working Duty

Define lifts per hour, full-load frequency, load spectrum, travel distance, shifts and annual operating hours. These data determine structural and mechanism service requirements.

05 · Hook Coverage

End approach, side approach, obstructions and safe operating zones determine whether the hook can reach every required pickup and placement point.

06 · Building and Runway

Existing or new runway beams require rail data, support spacing, wheel-load checks, alignment tolerances and an assigned structural approval responsibility.

07 · Motion Control

Specify lifting and travel speeds, low-speed range, acceleration, radio or pendant operation, anti-sway, positioning accuracy and any coordinated motion.

08 · Environment and Compliance

Temperature, dust, humidity, corrosion, washdown, hazardous-area classification, destination rules and inspection authority influence component and documentation selection.

Electric Wire-Rope Hoist

Common industrial selection for broader capacities, lifting heights and speed options. Drum capacity, rope reeving, fleet angle, brake, gearbox and trolley duty are matched to the operating cycle.

Electric Chain Hoist

Compact solution for lighter loads and localized handling. Chain container, reeving, duty, lifting speed and upper-limit arrangement must fit the available vertical envelope.

Low-Headroom Hoist

Offset geometry positions the hoist body around the girder to improve the highest hook elevation. The complete dimensional drawing must also preserve inspection and removal access.

Variable-Frequency Motion

VFD control supports smooth acceleration, controlled low speed and reduced load swing. Required minimum speed and positioning performance should be stated numerically.

Two-Hoist Handling

Two lifting units can support long loads where permitted by the bridge design. Individual capacities, combined loading, hook spacing and allowed control modes must be defined.

Below-Hook Attachment

Lifting beams, C-hooks, clamps, magnets and grabs add suspended weight and change load geometry. Attachment mass is included in crane capacity and headroom calculations.

Rail and Alignment

Rail section, gauge, straightness, elevation, joint condition and end stops influence wheel contact, skewing and travel quality. Crane runway tolerances are normally tighter than general building-steel tolerances.

Wheel Loads and Reactions

Maximum and minimum wheel loads, impact, side thrust and braking forces are assessed with the crane in governing hook positions. A replacement crane can impose different reactions at the same rated capacity.

Clearance and Access

Roof bracing, ducts, lights, sprinklers, cable trays and adjacent equipment require clearance throughout bridge travel. Safe access is required for hoist, drives, panels and wearing parts.

Incoming Power

Voltage, frequency, phase, isolation point, grounding and available fault level are confirmed before electrical design. Runway conductor scope and the interface to plant power are assigned in the offer.

Freestanding Runway

Independent columns can avoid loading an existing building. Column spacing, floor use, foundations, aisle traffic and future expansion become project design inputs.

Underhung Support

Suspended systems require beam-flange, hanger, connection and roof-reaction checks. The ability to hang a static load from a roof does not by itself establish crane runway suitability.

Machining and Fabrication

Moves plate, profiles, fixtures, machine parts and welded assemblies between cutting, machining, welding, inspection and dispatch stations.

Assembly and Production

Supports component positioning, subassembly transfer and line-side material supply where smooth low speed and accurate hook approach improve process control.

Warehouse and Logistics

Handles machinery, tools, dies, steel products and unit loads across storage bays without consuming the permanent floor lanes required by mobile lifting equipment.

Maintenance Facilities

Provides coverage for motors, pumps, gearboxes, vehicle components and production machinery during removal, inspection and reinstallation.

Precast and Building Materials

Transfers molds, reinforcement assemblies and finished components when load weight, lifting points, span and operating environment suit an electric-hoist bridge or gantry system.

Controlled or Hazardous Areas

Cleanroom, explosion-proof, corrosion-resistant or insulated variants are configured only after the required cleanliness, zone, gas or dust group, temperature class and material restrictions are declared.

Henan Mine Crane reports the successive supply of more than 300 intelligent cranes of various types for XCMG manufacturing operations. The equipment supports assembly and structural-component movement across engineering-machinery production processes, with project configurations covering bridge, gantry and specialized crane forms.

The program emphasizes high-precision positioning, digital controls, remote monitoring, fault warning and production-system integration. Reported project capacities extend from 5 t to 1,000 t across the complete mixed fleet. This range confirms that one factory program can require several crane architectures rather than one repeated model.

For a single-girder package within a comparable manufacturing environment, the transferable engineering priorities are load-path definition, repeatable low-speed motion, verified hook coverage, appropriate working duty, maintainable electrification and consistent control logic. The final design remains specific to each bay, capacity and production task.

What is the difference between a single girder crane and a single girder overhead crane?

Single girder crane is the broader term. A single-girder overhead crane travels on elevated runway beams, while a single-girder gantry crane is supported by legs travelling on ground rails.

How much does a single girder crane cost?

Current public positions range from approximately US$25,000–27,700 for selected 5 t component kits with hoists to approximately US$40,000 for a base 5 t bridge crane and US$47,600–52,300 for listed packaged configurations. Installed and engineered project values depend on scope.

When should a double-girder crane be selected?

Double girders are considered when capacity, span, duty, hook height, stiffness, trolley arrangement, service access or process equipment cannot be integrated efficiently into a single-girder system.

Can a single-girder crane use an existing runway?

Reuse is possible after structural capacity, rail section, gauge, alignment, end stops, clearances and proposed wheel loads are verified. Matching rated capacity alone does not confirm compatibility.

Which hoist is suitable for a single-girder crane?

Wire-rope hoists cover a broad range of industrial capacities, lifts and speeds. Chain hoists serve lighter compact handling. Low-headroom hoists improve upper hook elevation where building height is restricted.

Can a single-girder crane be supplied with radio remote control?

Pendant and radio control are common options. Cabin, PLC, variable-frequency motion, anti-sway, load monitoring and positioning functions are configured when justified by the process.

Does the crane quotation include runway and installation?

Runway steel, rails, columns, foundations, freight, erection, electrical feed, test weights and local inspection are included only when expressly listed. Every offer should contain a scope and exclusion schedule.

What documents support acceptance?

The handover package can include approved drawings, wheel-load data, electrical diagrams, manuals, component records, inspection results, factory test documents, commissioning settings and site load-test records.

Vertical Hoisting Motion

A wire-rope electric hoist, electric chain hoist or open-winch trolley raises and lowers the load. Capacity, lifting height, reeving, motor duty, brake arrangement and required creep speed determine the hoisting mechanism.

Trolley Cross Travel

The hoist or trolley moves across the bridge to position the hook across the bay. Side approach, trolley wheelbase, rail arrangement and service access affect usable coverage.

Bridge Long Travel

End carriages move the complete bridge along parallel runway rails. Wheel loads, drive coordination, rail alignment, skew behavior, buffers and end limits require review as one travel system.

Smooth Motion and Positioning

Single-speed operation can suit simple maintenance tasks. Dual-speed or variable-frequency control improves acceleration, deceleration and final positioning. Anti-sway and automatic positioning are available where production flow justifies the additional control scope.

Runway Survey and Structural Review

Existing runway beams and supporting structures require verified dimensions, rail condition, alignment, elevation, support spacing and allowable reactions. New buildings require early coordination of crane wheel loads and horizontal forces with the structural designer.

Headroom and Hook Coverage

Rail elevation, roof bracing, lights, ducts, sprinklers and adjacent equipment can restrict crane depth and hook travel. End and side approaches should be shown on the approved general arrangement rather than assumed from nominal span.

Power Distribution

The supply scope can include runway conductor bars or festoon systems, bridge cross-travel electrification, isolation, control transformer, protective devices and earthing. Interface positions and incoming cable responsibilities belong in the commercial schedule.

Multiple-Crane Operation

Shared runways may require anti-collision devices, working-zone limits and coordinated maintenance isolation. Tandem lifting requires a separately engineered control and load-sharing arrangement.

Hoisting Protection

Overload limitation, upper and lower limits, brakes, rope guidance, hook latches and project-specific overspeed or redundancy functions protect the lifting motion.

Travel Protection

Bridge and trolley travel can include end limits, buffers, emergency stops, motor protection, braking supervision and anti-collision devices for shared runways.

Controlled Positioning

Variable-frequency drives, low-speed approach, anti-sway, encoders and selected positioning functions support stable load movement and repeatable process handling.

Special Attachments

Lifting beams, magnets, grabs, clamps and purpose-built attachments require defined load cases, interlocks, power-loss response and inspection provisions.

QUOTE BASIS

Load, Span, Lift, Duty & Scope

Bridge Structure

Single girder, double girder or a process-specific multi-girder structure defines the load-carrying bridge arrangement.

Runway Interface

Top-running or underhung end carriages define how bridge reactions enter the runway and supporting building.

Lifting Mechanism

Chain hoist, wire-rope hoist or open-winch trolley determines lifting range, duty, reeving and maintenance requirements.

Process Function

Hook, grab, magnet, rotating beam, clamp or ladle devices establish the actual material-handling task and control logic.

01 · Single-Girder Overhead Crane

One bridge girder supports an electric hoist that normally travels on the lower flange or a dedicated track. The arrangement controls self-weight and equipment cost for general workshop, assembly, maintenance and warehouse handling.

02 · Double-Girder Overhead Crane

Two bridge girders support a trolley or hoist arrangement. The layout provides a broader structural platform for higher capacity, longer span, demanding duty, improved hook envelope or process equipment.

03 · Top-Running Overhead Crane

Bridge wheels travel on rails installed above the runway beams. The arrangement is common across light, medium and heavy industrial service and can use single- or double-girder bridges.

04 · Underhung Overhead Crane

Bridge end carriages travel on the lower flanges of suspended runway beams. The arrangement can extend hook coverage toward building sides and avoid runway rails above the support beams.

05 · Workstation Bridge Crane

A modular enclosed-track or light-rail bridge serves a defined production cell. Manual, electric or pneumatic motion can support repetitive ergonomic handling at lower capacities and shorter spans.

06 · Freestanding Bridge Crane System

Independent columns, runway beams and bracing carry crane loads when the building cannot support a crane or lease conditions restrict building attachment. Foundations and floor interfaces become part of the project.

Rated-Load Protection

The rated capacity includes the payload and every below-hook component. An overload device, upper and lower travel limits, end stops and operating procedures must match the selected crane and destination requirements.

Hoisting and Braking

Hoist motors, brakes, rope or chain, drum, sheaves and hooks are selected from the load spectrum and duty. Process or high-consequence service may require additional braking, monitoring or redundancy.

Bridge and Trolley Travel

Buffers, travel limits, anti-collision functions, warning devices and controlled acceleration protect the crane route. Shared runways require a defined operating and separation strategy.

Controls and Positioning

Pendant, radio, cabin and automated controls are selected for visibility, travel distance and process risk. Variable-frequency drives support smooth acceleration, controlled low speed and repeatable positioning.

Environmental Protection

Temperature, dust, moisture, corrosion, washdown and outdoor exposure determine enclosures, materials, coatings, heaters, cooling and component protection. Hazardous areas require a formal classification basis.

Load Attachment and Process Risk

Hooks, grabs, magnets, clamps, beams and ladle devices introduce different load-retention and control requirements. Attachment deadweight, geometry, power supply and failure response form part of the crane specification.

A top-running bridge places the crane wheels on rails above the runway beams. The arrangement supports a wide range of capacities and duties, but requires adequate space above the rail and verified runway reactions. Single-girder and double-girder bridges can both be top running.

An underhung bridge suspends the end carriages from the lower flanges of runway beams. It can improve side approach and avoid floor columns when the building is designed for the suspended loads. Runway flange geometry, lateral restraint, connection forces, roof loading and end clearance require engineering confirmation.

Hoist position does not define runway type. A hoist commonly runs below the bridge girder on a top-running single-girder crane; the bridge itself remains top running because its wheels operate above the runway rails.

A 3.2-million-ton premium special steel base required a coordinated fleet rather than one universal overhead crane type. Henan Mine Crane supplied more than 30 core equipment units covering steelmaking, refining, rolling and auxiliary production stages.

The reported fleet included 200 t foundry cranes, 200/50 t four-girder foundry cranes, 160/63 t cranes, 40+40 t cranes and overhead rotating electromagnetic beam cranes. Foundry cranes addressed molten-metal process loads, rotating electromagnetic beam cranes handled directional steel transfer, and smaller units supported auxiliary lifting.

The project demonstrates a central selection principle: crane architecture follows the process stage, load attachment, duty and hazard. Common capacity terminology cannot replace a function-by-function handling study.

What are the main types of overhead cranes?

The primary structural types are single girder and double girder. Runway arrangements are top running or underhung. Workstation and freestanding systems address localized or independent support needs, while foundry, grab, magnetic, explosion-proof and automated cranes serve special processes.

Is a bridge crane the same as an EOT crane?

Bridge crane, overhead bridge crane, overhead travelling crane and EOT crane commonly identify the same travelling-bridge equipment family. A procurement specification should still state girder arrangement, runway type, hoist or trolley, capacity, span, lift and duty.

What is the difference between single-girder and double-girder cranes?

Single-girder cranes use one primary bridge girder and commonly support an electric hoist. Double-girder cranes use two primary girders and provide a broader platform for higher capacities, longer spans, demanding duty, process trolleys or improved equipment access.

What is the difference between top-running and underhung cranes?

A top-running bridge travels on rails above runway beams. An underhung bridge travels beneath suitable runway beams. The terms describe the bridge-to-runway interface, not the position of the hoist on the bridge girder.

When is a freestanding bridge crane required?

A freestanding system is considered when the existing building cannot carry crane loads, reliable structural data is unavailable, attachment is restricted or a separate production bay requires independent support. Columns, bracing and foundations become part of the project.

Which overhead crane type suits heavy-duty production?

A double-girder crane with a duty-matched trolley is a common starting point for heavy loads and intensive service. The final choice depends on load spectrum, cycles, span, lift, process hazard, redundancy and maintenance requirements.

Is a monorail an overhead bridge crane?

A monorail hoist travels along one fixed beam or track and does not have a moving bridge spanning two parallel runways. It is an overhead lifting system, but it is not a bridge crane in the conventional structural sense.

Is a gantry crane an overhead crane type?

A gantry crane uses legs that transfer bridge loads to ground rails, wheels or another ground-supported travel system. It performs similar lifting motions but differs from a building-supported overhead bridge crane.

How much does an overhead crane cost?

Broad equipment-only bands begin near US$3,000 for limited light configurations and can exceed US$150,000 for large or complex equipment. Complete installed projects can cost substantially more after runway steel, electrification, freight, erection, testing and special process requirements.

What information is required for a quotation?

A formal RFQ should include maximum and typical loads, attachments, span, runway length, lift, building section, operating duty, speeds, controls, power, environment, project location, applicable requirements, delivery address and installation and acceptance scope.

PROJECT BOUNDARY

Equipment to Commissioning

Every component belongs to a continuous load and control path. Procurement documents should identify the responsible party for each item instead of assuming that a quoted bridge crane automatically includes the runway, building steel, incoming power, installation or load test.

The bridge and hoist determine basic lifting motion, but runway geometry governs travel quality and wheel loading. Electrification powers the moving equipment. Controls coordinate motion, protection and operating modes. The below-hook device connects the crane to the actual load. Inspection and handover records establish the approved configuration for commissioning and future maintenance.

01 · Bridge Structure

One or two girders, end connections, end carriages, wheels, buffers and required platforms form the travelling bridge. Span, deflection, fatigue duty and wheel reactions control the structural design.

02 · Hoist or Trolley

Chain hoists support lighter localized handling; wire-rope hoists serve common industrial cranes; engineered winch trolleys support heavy, high-duty or process applications.

03 · Runway Interface

Rails, runway beams, brackets, columns, end stops and foundations transfer vertical and horizontal crane forces into the building or independent support structure.

04 · Power and Electrification

Incoming isolation, conductor bars, festoon cables, cable reels, trolley power and grounding are selected from travel length, speed, environment and maintenance access.

05 · Controls and Safety

Pendant, radio, cabin or PLC control works with brakes, limits, overload protection, emergency stop, alarms, anti-collision and application-specific interlocks.

06 · Load-Handling Device

Hooks, lifting beams, C-hooks, magnets, grabs, clamps and vacuum devices change suspended weight, geometry, electrical demand, control logic and operating risk.

Single-Girder Top-Running System

An electric hoist travels below one bridge girder while end carriages run on rails above the runway. This is a cost-controlled starting point for general manufacturing, assembly, warehouse and maintenance service.

Double-Girder Top-Running System

A hoist trolley runs on or between two girders. The arrangement supports higher capacity, longer span, improved hook height, greater bridge stiffness, service platforms and demanding duty.

Single-Girder Underhung System

The bridge runs beneath suspended runway beams. It preserves floor space and can improve end approach where the roof or supporting structure is verified for crane reactions.

Multi-Support Underhung System

Several suspended runway lines support a long bridge across wide facilities. Henan Mine Crane product families include multi-support solutions for large industrial and aircraft-related buildings.

Freestanding Bridge Crane System

Independent columns and runway beams carry crane forces without relying on the existing building frame. Foundations, aisle layout, vehicle movement and future expansion control the layout.

Process and Automated System

Metallurgical, grab, magnetic, hazardous-area or PLC-controlled cranes integrate dedicated attachments, redundancy, sensing, interlocks, positioning and plant communication.

01 · Load Definition

Record maximum payload, normal payload, center of gravity, dimensions, lifting points, rigging and every below-hook component included in gross suspended load.

02 · Coverage and Geometry

Define rail-center span, runway length, pickup and placement positions, end approach, side approach, hook path and restricted zones.

03 · Lift and Headroom

State lowest pickup, highest placement, rail elevation, roof obstructions, load height, rigging depth and required maintenance clearance.

04 · Duty and Production Cycle

Provide lifts per hour, load spectrum, full-load frequency, travel distances, operating shifts, annual hours and consequence of downtime.

05 · Runway and Building

Identify existing or new runway steel, support spacing, rail data, building reactions, floor or foundation condition and structural responsibility.

06 · Motion and Positioning

Specify hoist, trolley and bridge speeds, low-speed range, acceleration, VFD requirements, anti-sway, positioning accuracy and synchronized operation.

07 · Environment and Hazard

Declare temperature, dust, humidity, corrosion, heat, washdown, cleanroom level, gas or dust classification and other abnormal exposure.

08 · Delivery and Acceptance

Define destination, voltage, governing requirements, documentation language, inspection stages, installation scope, test weights and acceptance authority.

Runway Power Supply

Insulated conductor bars suit long travel and regular operation; festoon systems suit defined cable-management layouts; cable reels solve selected travel and environmental conditions.

Motion Control

Contactors, soft starters or variable-frequency drives establish starting torque, acceleration, braking, low-speed positioning and mechanical stress on the crane and building.

Operating Stations

Pendant control provides direct local operation, radio control improves mobility and visibility, cabins serve selected process cranes, and PLC interfaces support automatic sequences.

Hoisting Protection

Overload limiting, upper and lower limits, service and holding brakes, rope guidance, hook safeguards and emergency stop are matched to the mechanism and risk assessment.

Travel Protection

End limits, buffers, rail sweeps, alarms and anti-collision functions reflect runway length, multiple-crane operation, restricted zones and plant traffic.

Automation and Recovery

Position feedback, anti-sway, load sensing, obstacle detection and plant communication require a defined safe state, manual recovery method and fault-diagnostic strategy.

Manufacturing and Assembly

Moves raw material, machine components, fixtures and finished assemblies between machining, welding, inspection and dispatch stations. Positioning speed and hook approach often control productivity.

Warehouse and Logistics

Handles coils, plates, machinery and unit loads across storage bays. Attachment type, storage geometry, inventory logic and collision zones determine the system configuration.

Steel Mill and Foundry

Transfers ladles, billets, slabs, coils and hot material under high duty and elevated risk. Redundancy, heat protection, braking and process interlocks become central requirements.

Bulk and Waste Handling

Uses grab buckets for ore, coal, biomass, slag, aggregate or waste. Bulk density, grab volume, fill factor, cycle time and hopper geometry establish productive capacity.

Power and Maintenance

Supports turbine, generator, pump and transformer installation or overhaul. Infrequent operation can still require high reliability, precise slow speed and long-term maintainability.

Hazardous and Controlled Areas

Explosion-proof, cleanroom, insulated or corrosion-resistant systems use project-defined equipment protection, materials, enclosures and documentation for the declared environment.

A 3.2-million-ton premium special steel production base required an integrated crane fleet across steelmaking, refining, rolling and auxiliary operations. Henan Mine Crane delivered more than 30 core equipment units in one coordinated project package.

The reported equipment included 200 t foundry cranes, 200/50 t four-girder foundry cranes, 160/63 t cranes, 40+40 t cranes and overhead rotating electromagnetic-beam cranes. Foundry cranes served molten-metal operations, rotating magnetic systems handled directional steel transfer, and smaller cranes supported auxiliary production and maintenance.

The project demonstrates why an overhead crane system should be matched to process stages rather than standardized around one bridge design. Capacity, girder arrangement, trolley, attachment, working class, control method and safety functions changed with the handled material and production risk, while project engineering and delivery remained coordinated.

View Project Case →

A complete system purchase connects approved operating data to design, fabrication, inspection, packing, site execution and final handover. Drawings and reaction data should be approved before bridge or runway interfaces are released.

A complete contracted system can include bridge structure, hoist or trolley, end carriages, travel drives, runway electrification, controls, protective devices, rails or runway steel, documentation, installation and testing. The exact boundary must be listed in the quotation.

Does an overhead crane price include the runway?

Runway beams, rails, columns, brackets and foundations are separate unless expressly included. Existing runway suitability also requires structural and alignment verification.

When is a double-girder system required?

Double-girder construction becomes relevant when capacity, span, duty, hook height, bridge stiffness, trolley arrangement, maintenance access or process equipment exceeds a suitable single-girder basis.

Can an overhead crane be installed in an existing building?

Installation is possible when the building and runway can safely accept crane reactions and required clearances. Otherwise, reinforcement or an independent freestanding runway may be required.

How is the required working class selected?

Working class follows load spectrum, operating frequency, travel distances, shifts, annual hours and process consequence. Rated capacity alone does not establish mechanism or structural duty.

What controls are available?

Common options include pendant, radio remote and cabin control. Variable-frequency drives, PLC automation, anti-sway, positioning and plant communication are available when justified by the operating process.

How long does installation take?

Duration depends on bridge size, runway readiness, building access, assembly method, electrical scope, local labor, permits and testing. A site-readiness review is required before a dependable schedule is issued.

Which documents support final acceptance?

The handover package can include approved drawings, reaction data, electrical diagrams, manuals, inspection records, component data, test results, commissioning settings and recommended spare-parts schedules.

Load and Hoist Protection

Overload limiting, upper and lower limits, brakes, rope or chain guidance, hook protection and low-speed control are selected for the hoisting mechanism and duty.

Travel Protection

End limits, buffers, rail sweeps, warning devices, emergency stops and anti-collision functions reflect runway length, traffic and multiple-crane operation.

Electrical Protection

Isolation, overcurrent protection, phase monitoring, earthing, enclosure rating, conductor arrangement and cable management match the plant supply and environment.

Process-Crane Safeguards

Molten metal, magnets, grabs, hazardous areas and automated operation require dedicated redundancy, monitoring, interlocks or operating restrictions.

Inspection and Test Planning

Drawing reviews, material checks, welding inspections, functional tests, protective-device settings and witness points should be agreed before manufacturing.

Operator and Maintenance Access

Platforms, walkways, clearances, isolation points and component-removal routes are evaluated with the building and maintenance strategy.

An overhead crane is only one part of the load path. Vertical wheel loads, horizontal forces, buffers, conductor equipment and maintenance access interact with runway beams, columns, foundations and the building frame. The crane supplier should issue approved reactions and rail requirements; the responsible structural party should verify the supporting system and connection details.

Top-running cranes place wheels on rails above the runway beams. Underhung cranes suspend end carriages from the lower flanges of compatible runway beams. A freestanding runway transfers crane loads through independent columns and foundations. Each arrangement creates different reactions, alignment tolerances and erection requirements.

Headroom should be verified on a dimensioned building section. Rail elevation, bridge depth, hoist or trolley position, highest hook, load height, rigging depth, roof bracing and service-clearance zones must be shown together. A lower equipment price has little value when the final hook height cannot complete the required lift.

A 3.2-million-ton premium special steel base required a coordinated crane fleet rather than one universal bridge-crane design. Henan Mine Crane supplied more than 30 core equipment units serving steelmaking, refining, rolling and auxiliary production stages.

The reported fleet included 200 t foundry cranes, 200/50 t four-girder foundry cranes, 160/63 t cranes, 40+40 t cranes and overhead rotating electromagnetic-beam cranes. Foundry cranes served molten-metal operations, rotating electromagnetic equipment handled directional steel transfer, and smaller cranes supported auxiliary tasks.

The procurement value lies in application separation. Each production stage received a crane structure, lifting mechanism, attachment, duty and control package matched to the material and hazard. The case demonstrates the capability expected from an industrial overhead crane supplier: process study, multi-type engineering, manufacturing coordination and project-wide delivery.

What is the difference between an overhead crane supplier and manufacturer?

A manufacturer designs and fabricates crane equipment. A supplier may be a manufacturer, distributor, integrator or contractor. The proposal should identify the legal manufacturer, design authority, equipment origin and party responsible for project performance.

Which documents should be requested before placing an order?

The pre-order package should include technical data, general arrangement, wheel loads, electrical demand, supply boundary, deviation list, document schedule, inspection plan, delivery schedule and commercial terms.

How can overseas overhead crane suppliers support local installation?

A practical structure combines factory engineering and remote or site supervision with a qualified local installation team. Responsibilities for lifting equipment, labor, permits, rail alignment, electrical work and acceptance should be assigned in writing.

Should the lowest overhead crane price determine the supplier?

No. Supplier comparison should use equal equipment, duty, runway, controls, documentation, freight, installation and testing boundaries. Omitted site work or inadequate duty can create a higher total project cost.

How is the required crane duty established?

Duty follows load spectrum, lifts per hour, travel distances, operating shifts, annual hours, speed and process consequence. Rated tonnage alone cannot determine motor, brake, bearing or structural fatigue requirements.

Can one supplier provide both the crane and runway?

Yes, when the contracted scope includes runway steel or an independent support structure. Structural responsibility, foundations, building interfaces, local calculations and installation tolerances must still be clearly assigned.

What should factory acceptance cover?

The agreed plan may cover document review, dimensions, mechanisms, electrical panels, motor operation, brakes, limits, warning devices, protective functions and available no-load or simulated tests before shipment.

How should spare parts be specified?

Critical spares should reflect the installed motors, brakes, drives, contactors, encoders, limits, ropes, wheels and controls. Part numbers, quantities, storage requirements and recommended commissioning spares should be listed.

Which crane type suits a standard workshop?

A single-girder electric wire-rope-hoist crane is a common starting point for moderate general-duty handling. Span, lift, headroom, duty, hook approach and runway reactions determine final suitability.

When is a process-crane supplier required?

Process-crane capability is required when molten metal, grabs, magnets, hazardous areas, automated production, high duty or critical loads create requirements beyond a conventional packaged-hoist bridge crane.

SUPPLY OPTIONS

Hoist Only, Crane Kit or Complete Crane

HOIST TYPES

Wire Rope, Chain, Low Headroom & Trolley

CRANE ARRANGEMENTS

Single, Double, Underhung & Multi-Hoist

SELECTION BASIS

Load, Lift, Duty, Headroom & Control

01 · Electric Wire-Rope Hoist

The principal choice for industrial bridge cranes requiring longer lifts, stable hook travel and medium to high operating duty. Rope reeving, drum capacity, motor thermal rating and brake selection are matched to the load spectrum rather than capacity alone.

02 · Electric Chain Hoist

A compact option for lighter capacities, shorter lifts and service or workstation duties. Chain-bag clearance, chain wear, duty rating, trolley fit and inspection access must suit the bridge arrangement and working environment.

03 · Low-Headroom Hoist

Positions the hoist body beside or between the girder profile to improve available hook height. It is selected where roof clearance is limited, but the complete trolley envelope, end approaches and maintenance access still require dimensional approval.

04 · Double-Girder Hoist Trolley

Travels on rails above or between two girders and supports greater capacity, lift or duty than a typical underslung monorail hoist. The trolley may carry one hoist, main and auxiliary hoists or coordinated lifting mechanisms.

05 · Multi-Hoist Crane System

Uses two or three hoists or trolleys for long loads, staged maintenance and coordinated positioning. Individual capacities, total permitted load, spacing, simultaneous-motion rules and load sharing are defined in the control philosophy.

06 · Special-Environment Hoist

Explosion-protected, corrosion-resistant, clean, dust-resistant or metallurgical configurations are engineered for the classified area and process risk. A standard hoist with isolated upgraded parts is not automatically suitable for a special environment.

A hoist should be selected from the handling cycle and installed geometry. General workshop loads may favor a compact single-girder wire-rope hoist, while long products may require two independently controlled hoists. Low-clearance buildings benefit from a side-mounted or between-girder trolley only after the full hook path and maintenance envelope have been checked.

The load itself defines the below-hook equipment and operating behavior. Machined assemblies, dies, coils, maintenance components and bulk-material attachments create different centers of gravity, starting torque, positioning accuracy and side-load risk. The crane layout must keep the rope or chain vertical during normal lifting.

Environmental data is part of the selection basis. Dust, humidity, corrosive vapor, washdown, outdoor exposure, high ambient temperature and classified hazardous areas affect enclosures, motors, brakes, cables, coatings and inspection intervals.

Intelligent Electric Hoist Crane Range

Henan Mine Crane product-family data covers 1–32 t capacity, 7.5–31.5 m span, 6–30 m lift and A5–A6 crane duty. Final values follow the approved project specification.

Double-Trolley Hoist Crane Range

Available product-family data covers 1+1–32+32 t combined capacities, 7.5–31.5 m spans, 6–30 m lift and A5–A6 duty for coordinated or independent handling.

Hoisting Brake System

The brake is selected for motor torque, load, speed, duty and governing requirements. Brake release monitoring, manual release control or additional braking functions are defined where the risk assessment requires them.

Upper and Lower Limits

Operating and final limits prevent normal overtravel. Their positions are established from the actual reeving, hook block, drum and site clearances; a limit device is not used as a routine stopping control.

Overload Protection

A calibrated load-limiting or monitoring device prevents lifting beyond the permitted setting. Display, alarm, shutdown and data functions are coordinated with the crane control philosophy.

Rope or Chain Monitoring

Inspection access is provided for wire rope, drum, sheaves, anchorage, load chain, sprocket and chain guide. Removal criteria follow the applicable rules and manufacturer instructions.

Controlled Travel and Anti-Sway

Variable-frequency trolley and bridge drives provide smooth acceleration and deceleration. Position feedback, speed zones and anti-sway functions can be added where repeatability or load stability is critical.

Emergency and Isolation Functions

Emergency stop, main isolation, travel buffers, warning devices and lockout provisions are incorporated into the complete crane. The final arrangement follows the destination and site risk assessment.

Hoisting Mechanism, Motion Control and Load Positioning

In a wire-rope hoist, the motor and gearbox rotate the drum while the reeving system converts rope movement into controlled hook travel. The brake holds the suspended load when power is removed. Sheave arrangement, rope falls and drum capacity determine hook speed, stability and available lift. A chain hoist uses a load sprocket and calibrated chain but follows the same requirement for matched motor, brake, limits and trolley duty.

Single- or dual-speed contactor control provides fixed operating speeds. Variable-frequency control permits adjustable acceleration, deceleration and creep motion, reducing load swing and supporting accurate placement. The selected control mode must remain compatible with brake timing, motor cooling and the required duty cycle.

Multi-hoist systems require a defined operating matrix. The design states whether hoists may run independently, together or in synchronized mode; which combined loads are permitted; and how unequal loading, encoder disagreement or a drive fault is handled. No synchronization feature replaces correct rigging or an approved lifting plan.

Selection and Interface Package

Approved data sheet, duty calculation, hoist and trolley arrangement, reeving diagram, hook approaches, wheel loads, girder or rail interface, power demand and equipment boundary.

Design and Control Documents

General arrangement, electrical diagrams, motor and brake data, control narrative, limit and interlock schedule, component list, inspection points and applicable compliance matrix.

Manufacturing and Inspection Records

Material and component certificates, welding and dimensional records where applicable, gearbox and brake checks, rope or chain records, electrical inspection and coating documentation.

Testing and Handover Records

Factory functional checks, direction and limit verification, brake test, overload-device setting, site load-test plan, commissioning reports, manuals, spare-parts list and training records.

Existing-Crane Survey

For replacement work, record beam or rail dimensions, trolley gauge, hook approaches, power, controls, wheel loads, bridge condition and available access. Verify the supporting crane before ordering the hoist.

Installation and Alignment

Install trolley wheels, buffers, festoon, limits, rope or chain, hook block and controls under approved procedures. Check alignment, clearances, fasteners, lubrication and electrical protection before energization.

Commissioning and Load Test

Verify directions, brakes, limits, overload protection, pendant or radio functions and all crane motions. Conduct no-load, rated-load and statutory tests under the agreed acceptance plan.

Is an overhead crane hoist the same as an overhead crane?

No. The hoist raises and lowers the load. The trolley moves across the bridge, and the bridge travels along the runway. A complete crane combines all of these systems with controls and electrification.

Should an overhead crane use a chain hoist or wire-rope hoist?

Chain hoists commonly suit lighter, shorter-lift service. Wire-rope hoists generally suit longer lift, greater speed and industrial production duty. Final selection follows capacity, duty, headroom and maintenance requirements.

What information is needed to replace an existing hoist?

Provide capacity, lift, duty, power, controls, beam or trolley rail dimensions, wheel gauge, hook approaches, headroom, existing drawings and clear photographs. The supporting crane condition must also be verified.

Can a larger hoist be installed on an existing crane?

Not without engineering verification. Greater capacity or self-weight can exceed girder, end truck, runway, electrical or braking limits. The entire load path and supporting structure must be checked.

What is a low-headroom overhead crane hoist?

It is a compact hoist-trolley arrangement that places machinery beside or within the girder envelope to increase usable hook height. Actual benefit depends on the complete crane and building geometry.

Can two overhead crane hoists lift one load?

Yes, when the crane, controls, rigging and operating procedure are designed for the lift. Individual capacity, total load, spacing, synchronization, load sharing and fault response must be defined.

Which hoist control is best for precise positioning?

Variable-frequency control with suitable motor feedback and brake coordination provides smooth acceleration and creep speed. Required positioning tolerance, load behavior and duty determine the final control package.

How much does an overhead crane hoist cost?

Price depends on capacity, lift, duty, headroom, speed, trolley, controls and compliance. Current 5 t retail examples range from about US$17,800 for a hoist to about US$28,000–31,000 for component kits.

Does a crane kit include the bridge and runway steel?

Not necessarily. Many kits include the hoist, trolley, end trucks, controls and festoon but exclude the main girder, runway, electrical feed, fabrication and installation. Every quotation must list inclusions.

How is hoist duty selected?

Duty is selected from the number of starts, operating time, load spectrum, lifting height, speed, shifts and environment. A frequently cycled partial load can require more duty than an occasional full-capacity lift.

FINAL BASIS

Project-Specific Quotation

01 / EVALUATION PERIOD

Financial Planning Horizon

A common evaluation period must be applied to equipment, operating expense, major service and residual value before alternative systems are compared.

02 / DUTY

Load Spectrum and Work Cycle

Average lifted load, maximum load, lifts per hour, travel distance and operating shifts determine mechanism duty, wear rate and service demand.

03 / INFRASTRUCTURE

Runway and Building Condition

Runway capacity, alignment, columns, foundations, clearances and power distribution can represent a substantial share of the installed project cost.

04 / ENERGY

Motors, Controls and Utilization

Installed motor power alone does not equal consumption. Loaded movement, idle time, travel profile, drive efficiency and local tariff establish annual energy cost.

05 / MAINTAINABILITY

Service Access and Spare Parts

Accessible brakes, wheels, electrical panels and lifting mechanisms reduce service time. Standardized components and planned spares support predictable maintenance.

06 / AVAILABILITY

Production Criticality

A process crane that controls production flow requires a different reliability, redundancy and spare-parts strategy from an intermittently used maintenance crane.

Capital Expenditure

Crane, controls, attachments, runway, building reinforcement, electrification, freight, erection, commissioning, testing and initial documentation.

Operating Expenditure

Electricity, routine inspections, preventive maintenance, lubrication, wear parts, corrective repairs, technical support and operator or maintenance training.

Operational Risk

Lost production contribution, idle labor, expedited parts, emergency service and recovery activity created by unplanned crane unavailability.

Crane Equipment

Bridge, end trucks, hoist or trolley, controls, festoon, power feed, safety devices, attachment and specified access.

Runway and Structure

Rails, beams, columns, brackets, stops, foundations, reinforcement, survey, alignment and structural verification.

Electrical Interface

Incoming power, isolators, conductor system, cables, earthing, protective devices and production-system interfaces.

Logistics and Handling

Export packing, inland transport, sea or air freight, insurance, import charges, unloading, storage and site handling.

Site Execution

Access equipment, erection labor, supervision, wiring, commissioning, load test, permits, shutdown work and acceptance.

Hoisting, trolley travel and bridge travel do not normally operate at full motor load for every energized hour. A weighted utilization factor should reflect loaded travel, unloaded travel, acceleration, braking, idle time and production cycle.

Variable-frequency drives can improve movement control and may reduce energy use in suitable duty cycles. Actual savings depend on speed profile, load spectrum, braking method, drive efficiency and idle-power management.

ILLUSTRATIVE CALCULATION

10 Ton Single-Girder Crane

13.8 kW installed motor power × 15% weighted utilization × 2,000 energized hours × US$0.12/kWh

≈ US$497 per year

This calculation illustrates the method only. Demand charges, auxiliary loads, local tariff structure, duty cycle and actual drive loading require project-specific values.

Downtime can outweigh the purchase-price difference when a crane is integral to furnace charging, coil movement, assembly flow, warehouse dispatch or equipment maintenance. The calculation must use site economics rather than a universal hourly figure.

Expected annual exposure can be estimated by multiplying the cost per event by the forecast event frequency, then testing conservative and critical scenarios.

Availability Measures for Critical Service

• ✓Correct duty classification and load-spectrum definition
• ✓Critical spare parts held against verified lead times
• ✓Service access incorporated into crane arrangement
• ✓Inspection records linked to condition-based action
• ✓Redundancy specified only where process risk justifies it

Specify the Actual Duty

Measured loads, cycles and travel distances prevent both under-specification and unnecessary mechanism cost.

Verify Geometry Early

Accurate span, hook height, approaches and building loads reduce redesign, structural modification and site delay.

Standardize Service Components

Documented motors, brakes, bearings, contactors and drives simplify stocking and technician training.

Design for Maintenance

Safe access to brakes, wheels, panels and lifting machinery reduces planned and corrective service duration.

Plan Critical Spares

A risk-ranked initial spare package protects availability without creating excessive inventory.

Apply Controls with Purpose

Variable speed, positioning, anti-sway and monitoring should be tied to measurable handling, quality or availability requirements.

Henan Mine Crane connects commercial scope to project-specific drawings, component schedules, inspection requirements and delivery documentation. This control reduces ambiguity during bid comparison and establishes a technical baseline for installation and lifecycle service.

• ✓Approved general arrangement, hook approaches, wheel loads and building interfaces
• ✓Named component schedule with controlled substitution requirements
• ✓Inspection and test plan with agreed records and witness points
• ✓Electrical drawings, operating manuals and preventive-maintenance instructions

What is the average cost of an overhead crane?

Common factory-supplied industrial crane equipment can range from approximately US$5,000 to US$130,000 or more. Installed project cost varies materially with capacity, span, runway, building work, logistics and local installation.

What is the difference between overhead crane price and overhead crane cost?

Price normally describes the quoted acquisition value and stated supply scope. Cost includes the installed project, energy, inspections, service, spare parts, repairs, downtime and residual value across the selected evaluation period.

Does crane equipment cost include the runway?

Runway beams, rails, columns, brackets, foundations, stops and structural verification are separate unless expressly listed in the quotation. Existing runway suitability also requires confirmation.

How is annual overhead crane energy cost calculated?

Multiply installed motor power by a weighted utilization factor, annual energized hours and the applicable electricity tariff. Movement profile, load spectrum, drive losses, idle loads and demand charges should be included where relevant.

How much should be budgeted for crane maintenance?

The maintenance budget should be built from required inspections, preventive-service hours, expected wear parts, access equipment, labor rates and major-service provisions. A universal percentage is not reliable across different duties and environments.

How is overhead crane downtime cost estimated?

Multiply lost production contribution per hour by unavailable hours, then add idle labor, emergency service, expedited parts and recovery expense. Expected annual exposure also considers event frequency.

Is a single-girder crane always the lowest-cost choice?

Single-girder construction often has a lower acquisition cost when technically suitable. Double-girder construction can provide the required duty, span, hook height, trolley arrangement or service access and may offer better lifecycle value in demanding applications.

What evaluation period should be used for total ownership cost?

The period should match the organization’s capital-planning policy and intended service horizon. Every proposal must use the same period, discount rate, escalation assumptions and residual-value method.

Which details are required for an accurate overhead crane cost proposal?

Capacity, load characteristics, span, lift, runway length, duty cycle, speeds, controls, environment, power supply, building data, destination, installation scope and availability objectives are required.

How should competing crane quotations be compared?

Confirm the same technical configuration, duty, component scope, runway boundary, Incoterm, installation work, testing, documentation, warranty conditions, spares and evaluation period before comparing total cost.

QUOTE BASIS

Equipment + Project Scope

01 · Single-Girder Overhead Crane

One bridge girder supports an electric chain or wire-rope hoist. The structure controls self-weight and equipment cost for general workshop, warehouse, assembly and maintenance handling.

02 · Double-Girder Overhead Crane

Two bridge girders support a packaged hoist or top-running trolley. The arrangement suits higher capacities, longer spans, heavier duty, improved hook height and process equipment.

03 · Underhung Bridge Crane

End carriages travel beneath suspended runway beams. The configuration preserves floor clearance and can improve end approach where the building is verified for suspended runway reactions.

04 · Freestanding Bridge Crane System

Independent columns, runway beams and bracing carry crane loads when the existing building cannot accept them. Foundation and floor interfaces become part of the project.

05 · Special-Purpose Bridge Crane

Grab, magnet, clamp, rotating beam, C-hook, ladle beam or another attachment integrates the crane with a specific material-handling process and risk profile.

06 · Automated Bridge Crane

Position feedback, PLC control, anti-sway, collision management and plant interfaces support repeatable semi-automatic or unmanned material flow.

Top-running and underhung identify the bridge-to-runway relationship; single girder and double girder identify the bridge structure. These terms should not be treated as competing descriptions. A crane can be a top-running single-girder system or a top-running double-girder system.

The correct commercial short list follows the load, usable hook height, building support, production cycle and process consequence rather than a fixed capacity threshold.

Installation and Commissioning

Unloading, assembly, erection, alignment, power connection, drive setup, functional checks, proof testing and training.

New, Used or Modernized Equipment

New equipment provides an application-specific design basis. Used or modernized cranes require records, structural assessment, component condition review and runway compatibility verification.

A major Yangtze River bridge project required a 300 t double girder overhead travelling crane for heavy material handling and large-component installation. The equipment was configured as project-specific lifting machinery rather than an enlarged general workshop crane.

The crane used a modular design, hardened-gear transmission, integrated electrical system and full variable-frequency control. Controlled acceleration and low-speed motion supported heavy-component positioning, while modular component selection simplified future maintenance and spare-parts management.

Reserved interface capacity allowed later functional upgrades without redesigning the complete machine. The project demonstrates the importance of matching structural design, mechanisms, controls, runway reactions, transport splits and site commissioning to one approved operating basis. The same engineering sequence applies to smaller industrial bridge-crane purchases even when capacity and complexity are lower.

What is included in an overhead bridge crane sale?

The included scope may range from a bridge kit to a complete installed system. A valid proposal should identify the bridge, hoist or trolley, runway, electrification, controls, documents, freight, installation and testing separately.

How is single girder selected instead of double girder?

Single girder normally controls self-weight and cost for moderate load, span and duty. Double girder supports higher capacity, longer span, demanding duty, improved hook height and larger trolley arrangements.

What is the difference between top-running and underhung cranes?

A top-running bridge travels above runway rails. An underhung bridge travels below suspended runway beams and can preserve floor clearance, subject to verified roof and runway capacity.

Can an overhead bridge crane be installed in an existing building?

Yes, after structural and dimensional verification. The project may require building reinforcement, new runway beams or a freestanding support structure.

How much does an overhead bridge crane cost?

Current market examples place common 5–10 t single- and double-girder systems around US$40,000–100,000 depending on configuration and installation scope. A project quotation remains necessary.

Why do quotations for the same tonnage differ?

Span, lifting height, working class, hoist architecture, speeds, runway scope, electrical equipment, documentation, freight, installation and testing can differ even when rated capacity is identical.

Is a used overhead bridge crane suitable for a new facility?

Suitability depends on structural records, remaining life, mechanism condition, electrical compliance, runway compatibility, spare-parts support and the cost of modification, transport and recertification.

Which control method is normally selected?

Pendant control suits local operation, radio control improves mobility, and a cabin supports long travel or severe environments. Automated systems add positioning, anti-sway and plant interfaces.

What standards apply to an overhead bridge crane?

The governing basis depends on destination and crane type. ASME B30.2 applies to defined top-running bridge cranes, while EN, ISO, FEM and national requirements may govern other projects.

What information produces the fastest accurate quotation?

Capacity, span, lifting height, duty, load description, runway drawings, control method, power supply, environment, destination and a written scope boundary provide the essential basis.

Open-web bridge construction reduces wind area and can suit long outdoor spans, construction yards and precast operations. Published families extend from 5 t to 100 t.

Rubber-Tired Gantry Cranes

Mobile systems provide flexible yard travel without fixed longitudinal rails. Steering, pavement loading, power system, stability and operating route require project-specific coordination.

Container and Heavy-Lift Gantry Cranes

RMG, RTG, shipbuilding and custom heavy-lift systems combine process-specific spreaders or lifting beams, higher working duty, coordinated drives and advanced control functions.

A gantry crane is engineered as a coordinated structure rather than assembled from isolated components. Bridge stiffness, leg geometry, wheel base, trolley position, wind load, braking forces and rail tolerances influence wheel reactions and travel behavior. The electrical and control design must match the selected mechanisms, duty cycle and operating environment.

Manufacturing records can include material identification, welding procedures, welder qualifications, nondestructive examination where specified, bridge camber and span inspection, wheel-alignment records, gearbox and brake information, electrical diagrams, coating checks and factory functional tests. Required records and witness points are agreed before production.

Structural Engineering

Capacity, span, lift, duty, wind, trolley reactions, fatigue, deflection, transport splits and erection method define bridge, leg and end-carriage design.

Mechanism Selection

Hoist, trolley and gantry travel motors, brakes, gearboxes, wheels, drums, ropes and limits are selected for load spectrum, speed and operating hours.

Electrical Integration

Panels, VFDs, conductor or cable systems, pendant, radio, cabin or PLC controls are coordinated with voltage, enclosure, alarms and interlocks.

Parts and Service Planning

Define commissioning spares, operating spares, wear parts, critical components and the information required for accurate replacement.

Henan Mine Crane supplied a 700 t gantry crane for the construction of a major Yangtze River bridge steel tower. The tower reaches approximately 350 m, while principal lifted components were reported in the 500–650 t range. The project required a custom heavy-lift system rather than a standard catalogue configuration.

The procurement significance extends beyond rated capacity. A project of this scale requires controlled structural design, transportable fabrication modules, coordinated lifting mechanisms, synchronized travel, defined wind limits, engineered foundations or rails, erection planning and a project-specific inspection and commissioning program.

Comparable heavy-lift enquiries should include component mass and geometry, lifting points, center of gravity, required travel path, assembly sequence, wind conditions, allowable ground reactions, synchronization tolerance and acceptance authority. These inputs establish the safe operating envelope and contract scope.

COST BOUNDARY

Crane, Rails, Freight, Erection & Tests

QUOTE BASIS

Load, Span, Lift, Duty & Environment

01 · Portable Gantry Crane

A fixed- or adjustable-height frame on casters or wheels for maintenance and workshop lifting. It has the lowest structural cost, but published prices often exclude the hoist and trolley. Capacity, span, height, wheel type and motorization determine the final package.

02 · Single-Girder Gantry Crane

An electric hoist travels below one main girder supported by two legs. It is generally the most economical powered rail-mounted choice for light and medium industrial duty where capacity, span and operating frequency remain within the approved design range.

03 · Double-Girder Gantry Crane

Two box girders support a rail-mounted hoist or winch trolley. The configuration carries higher capacity and duty and provides greater lifting height or hook approach, but adds structural steel, trolley machinery, wheel loads, shipping volume and erection work.

04 · Semi-Gantry Crane

One side travels on an elevated runway and the other on a ground rail. It can reduce the number of supporting legs and use existing building structure, but the elevated runway, building reactions and ground-side foundation must be verified before comparing total cost.

05 · Truss Gantry Crane

A lattice or truss girder can reduce self-weight and wind area for long-span outdoor service. Fabrication complexity, corrosion protection, bolted shipping sections and site assembly influence whether it is more economical than a box-girder alternative.

06 · Special and Heavy-Lift Gantry Crane

Shipbuilding, bridge construction, hydropower, precast, container and rubber-tyred systems use project-specific structures, attachments, drives and controls. Their price is developed from engineering scope and site interfaces, not a standard tonnage table.

The lowest-priced structure is not always the lowest-cost solution. A portable crane may suit occasional maintenance inside a workshop, while a powered rail-mounted crane is more appropriate for repetitive yard handling. A semi-gantry arrangement can save floor space, but only when the existing building can accept the elevated runway reactions.

Outdoor operation adds wind, rain, temperature and corrosion requirements. Rail clamps, storm anchors, anemometers, weatherproof electrical equipment, protected motors and the specified coating system should be priced with the crane rather than added after manufacture. Coastal sites require a corrosion strategy based on the actual exposure.

Process attachments also affect price. A hook crane, grab crane, magnetic crane, precast beam crane and container crane may share a rated capacity while using different trolleys, power supplies, control logic and duty classifications.

Single-Girder Product-Family Range

Henan Mine Crane product data covers 1–32 t capacity, 4–35 m span and 4–12 m lift for the principal electric-hoist range. Final values follow the approved project.

Double-Girder Product-Family Range

MG double-girder product data covers 5–500 t capacity, 8–40 m span, 6–30 m lift and A3–A8 duty, subject to project-specific engineering.

Capacity and Duty Are Separate

Rated load sizes the crane, while the load spectrum and operating frequency establish fatigue and thermal duty. A frequently cycled 10 t crane can require a more substantial mechanism than an occasional-use 20 t crane.

Span Changes More Than Steel Weight

Increasing span affects girder depth, stiffness, wheel loads, shipping sections, leg geometry and erection method. The working width and rail-center span should be defined separately.

Hoist or Winch Trolley Selection

Packaged electric hoists reduce initial cost for general duty. Open-winch trolleys support higher capacity, lift, duty, redundancy and process customization but require more engineering and maintenance access.

Outdoor and Wind Protection

Operational wind limits, storm anchoring, rail clamps, anemometers, weatherproof cabinets, heaters, cooling and coatings should match site conditions. These features affect both crane price and civil design.

Power and Control Architecture

Long-travel cable reels, conductor systems, festoons, diesel-electric or hybrid power, radio control, cabins, VFDs, PLCs and automation create different equipment and commissioning scopes.

Shipping and Site Assembly

Girder shipping splits, containerization, oversize transport, site cranes, welding, bolting, rail alignment and load-test weights influence the delivered and installed cost beyond factory equipment price.

Equipment Price, Landed Cost and Installed Cost

The equipment price covers only the items named in the supplier schedule. It may include the steel structure, hoist or trolley, travel mechanisms, electrical panels, pendant or radio control and crane-mounted electrification. It may exclude rails, foundations, power feed, attachment, packing, freight and site work.

Landed cost adds export packing, inland transport, ocean or road freight, insurance, import handling, duties and taxes under the agreed trade term. Large gantry girders can require split construction, open-top containers, flat racks, breakbulk transport or project cargo planning. Shipping design should be agreed before fabrication.

Installed cost adds civil works, rail installation, electrical supply, erection equipment, skilled labor, alignment, commissioning, load testing, statutory inspection and training. A complete budget should also identify spare parts, planned maintenance and future relocation or dismantling where applicable.

Design Basis Package

How much does a gantry crane cost?

Current public prices range from about US$1,300 for small basic portable frames to US$80,000 for preliminary 16–20 t double-girder equipment bands. Larger and process-specific cranes require project quotations.

Why do two gantry cranes with the same capacity have different prices?

Span, lift, duty, hoist or trolley type, cantilevers, runway length, controls, wind design, corrosion protection, standards and included services can differ even when rated capacity is identical.

Does a portable gantry crane price include the hoist?

Often it does not. Many retail prices cover only the frame, beam, uprights and wheels. The product schedule should confirm the hoist, trolley, electrification, end stops, freight and assembly.

What is the typical 5 ton gantry crane price?

Published 5 t portable frames are approximately US$5,300–14,700 or more. Preliminary 5 t powered industrial equipment bands are about US$15,000–25,000 for single girder and US$30,000–45,000 for double girder.

What is the typical 10 ton gantry crane price?

Published 10 t portable industrial cranes are approximately US$15,600–40,000 or more. Preliminary powered equipment bands are about US$18,000–30,000 for single girder and US$35,000–60,000 for double girder.

Is a single-girder gantry crane always cheaper?

It normally uses less structural steel and a simpler hoist arrangement, but suitability depends on capacity, span, lift and duty. A forced single-girder design can become inefficient when the application requires greater stiffness or hook height.

Does the quoted crane price include foundations and rails?

Only when explicitly listed. Foundation design, concrete, reinforcement, rail beams, rails, clips, grounding, drainage and alignment are frequently separate site scopes.

How much does shipping add to gantry crane cost?

Shipping depends on girder length, weight, containerization, port route, destination and trade term. Long or heavy sections may require flat-rack, open-top, breakbulk or project-cargo transport.

Can an existing concrete slab support a portable gantry crane?

The floor must be checked for wheel loads, slab capacity, flatness, joints and movement route. A portable crane does not automatically eliminate structural verification or operational restrictions.

What is the fastest way to obtain an accurate price?

Submit capacity, load details, span, lift, runway length, duty, power, controls, wind and environment data, site drawings, destination, standards and a clear supply-scope matrix.
