What Is an Overhead Bridge Crane?
An overhead bridge crane is a travelling lifting system in which a bridge spans two parallel runways. A hoist or trolley moves across the bridge, while the bridge travels along the building bay. Vertical lifting, trolley cross travel and bridge long travel provide rectangular working coverage without occupying primary production floor space.
Bridge crane, overhead crane, overhead travelling crane and EOT crane commonly describe the same equipment family. A complete purchasing description also identifies bridge structure, runway arrangement, lifting mechanism, rated capacity, span, lifting height, working class, speed, control method, environment and attachment.
An overhead bridge crane offered for sale is not a standard commodity identified by tonnage alone. A 10 t crane for occasional machine maintenance has a different mechanism and structural basis from a 10 t process crane making repeated production lifts. The runway and building also form part of the load path, even when they are excluded from the crane supplier’s commercial scope.
Henan Mine Crane supplies new equipment configured for the declared application. A technically complete proposal identifies what is included, what remains site responsibility and which information must be approved before manufacturing. This distinction prevents an equipment-only price from being compared with a complete installed system.
Overhead Bridge Crane Types Available
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.
Selection Considerations
A reliable overhead bridge crane purchase begins with the handling process and facility geometry. The following inputs determine whether the proposed equipment can meet production, structural and acceptance requirements.
01 · Gross Suspended Load
Record maximum and normal payloads, hook block, lifting beam, clamp, magnet, C-hook, slings and every component carried below the hoist.
02 · Span and Coverage
State runway rail-center span, bridge travel length, pickup and placement zones, side approach, end approach and any transfer area.
03 · Lift and Headroom
Define lowest pickup, highest hook elevation, rail level, roof obstruction, load height, rigging depth and required extraction distance.
04 · Duty and Load Spectrum
Provide lifts per hour, shifts, annual operating hours, travel distance, normal load and frequency of operation near rated capacity.
05 · Runway and Building
Confirm rail profile, runway beams, column spacing, brackets, foundations, allowable reactions and available structural drawings.
06 · Motion and Control
Specify lifting and travel speeds, low-speed range, positioning tolerance, pendant, radio, cabin, variable-frequency drives and automation.
07 · Environment and Material
Identify temperature, dust, humidity, corrosion, hazardous classification, outdoor exposure, hot material and cleanliness requirements.
08 · Delivery and Acceptance
Define destination, power supply, governing requirements, documentation language, inspection authority, installation and commissioning boundary.
Procurement control: capacity, span and lifting height do not define a complete crane. Working class, runway reactions, hoist architecture, environment, documentation and commercial exclusions must be compared at the same time.

Project Case: 300 t Double Girder Crane for Major Bridge Construction
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.

Overhead Bridge Crane for Sale FAQ
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.
