What Is an RTG Crane for a Container Yard?
An RTG crane, or rubber-tyred gantry crane, is a mobile container-stacking crane carried by multi-wheel rubber-tyred bogies. It straddles several container rows and a truck or terminal-tractor lane, lifts containers with a telescopic spreader and travels along the storage block without fixed runway rails.
A typical container-yard starting point is 40.5 t under spreader, five to seven container rows plus one vehicle lane, and one-over-four to one-over-six stacking. Final capacity, span, lift height, speed, power source and fleet quantity follow the approved yard plan and operating model.
RTGs are used in marine terminals, inland container depots, rail-intermodal facilities and logistics hubs where storage density and block mobility are both required. The absence of travel rails supports phased expansion and equipment relocation between compatible blocks.
RTG Crane Selection Considerations
Container and Lift Profile
ISO size mix, maximum gross mass, high-cube share, reefer volume, out-of-gauge handling and single- or twin-lift operation establish capacity and spreader scope.
Yard Block Geometry
Row count, truck lane, stack height, row pitch, block length, transfer positions and block-end turning area define the crane envelope.
Throughput and Duty
Annual TEU, peak moves, rehandle ratio, operating shifts, productive hours, transfer-vehicle demand and availability target control mechanism duty and fleet size.
Power and Emissions
Grid capacity, fuel and electricity costs, block-change frequency, cable routes, charging strategy and local emissions targets affect power architecture.
Pavement and Environment
Allowable wheel load, pavement settlement, gradient, drainage, wind, temperature, salt fog, rainfall, dust and seismic criteria require coordinated civil and crane design.
Control and TOS Integration
Cab, remote or automated operation; positioning; OCR; anti-sway; communications; diagnostics; TOS/ECS interfaces and recovery modes require defined ownership.
RTG Crane Configurations Compared
| Configuration | Operating Strength | Project Check | Typical Yard Pattern |
|---|---|---|---|
| Diesel-Electric RTG | Independent power and frequent block changes | Fuel use, engine service, noise and local emissions | Developing yards or blocks without reliable grid access |
| Hybrid RTG | Mobile operation with energy recovery and reduced engine loading | Battery lifecycle, thermal management and control complexity | High-utilization blocks requiring mobility and fuel reduction |
| Cable-Reel Electric RTG | Low local emissions, low noise and reduced engine maintenance | Substation, cable route, changeover and block-transfer method | Stable long blocks with limited cross-block movement |
| Busbar Electric RTG | Continuous grid power along permanent blocks | Conductor infrastructure, transfer interface and isolation safety | Permanent high-throughput container blocks |
| Battery-Electric or Automated RTG | Zero local tailpipe emissions and automation-ready control | Charging cycle, battery sizing, controlled traffic and system integration | Electrified terminals with mature TOS and safety zoning |
Published RTG Crane Specifications
The following values are the published Henan Mine Crane RTG product-family range. Contract values remain drawing-specific because span, lift height, speed and power depend on the approved yard geometry and duty cycle.
| Parameter | Published Range | Project Definition |
|---|---|---|
| Lifting Capacity | 35 t, 40.5 t, 50 t or customized | State under-spreader or hook basis |
| Span | 8–35 m or customized | Rows, truck lane and clearances |
| Lifting Height | 6–21 m or customized | Stack height and service clearance |
| Work Class | A6–A8 | Load spectrum, cycles and design life |
| Published Temperature | −25°C to +40°C | Site extremes and component package |
Planning Speed Range
The Henan Mine Crane RTG specification guide lists typical planning ranges of 12–25 m/min for loaded hoisting, 30–60 m/min for trolley travel and 45–90 m/min for gantry travel. Final values follow drive sizing, stability, anti-sway performance and terminal traffic analysis.
5+1, 6+1 and 7+1 RTG Yard Layouts
RTG layout shorthand states the number of container rows plus the vehicle lane under the gantry. A 6+1 RTG spans six storage rows and one truck or terminal-tractor lane. Wider spans increase block coverage but also affect trolley travel, structural mass, wheel loads, drive power and wind response.
| Layout | Yard Effect | Engineering Focus | Typical Application |
|---|---|---|---|
| 5 Rows + 1 Lane | Narrower block and shorter trolley path | Brownfield geometry and moderate density | Inland depot or constrained terminal |
| 6 Rows + 1 Lane | Balanced density and truck interface | Cycle time, lane clearance and wheel load | General marine or intermodal yard |
| 7 Rows + 1 Lane | Higher storage density per block | Longer span, trolley travel and pavement demand | High-volume terminal with planned blocks |
Stacking Height
“One over five” means five stored containers with clearance to carry one container above the stack. High-cube containers, pavement tolerances, tyre deflection, spreader depth, twistlock engagement, structural deflection and operating clearance all enter the vertical envelope.
One-over-four reduces structural height and wheel load. One-over-five commonly balances density and access. One-over-six increases storage density but also raises wind exposure, lift height and rehandle sensitivity.
RTG, RMG and Straddle Carrier Compared
| System | Mobility | Storage Model | Infrastructure | Strongest Fit |
|---|---|---|---|---|
| RTG Crane | Moves between compatible blocks | Dense multi-row blocks | Wheel paths and optional electrical works | Flexible allocation and phased growth |
| RMG Crane | Fixed to a rail runway | Wide, repeatable blocks | Rails, foundations and power distribution | Permanent high-throughput layouts and automation |
| Straddle Carrier | Free-routing carrier | Transport and stacking by one machine | Traffic lanes and maintenance facilities | Fast point-to-point movement and flexible routing |

Spreader, Anti-Sway, Automation and Yard Infrastructure
Container Interface
A telescopic spreader normally covers 20 ft and 40 ft ISO containers; 45 ft handling, twin lift or special interfaces are specified separately. The rated-load definition must state whether capacity is measured below the spreader and whether spreader self-weight is excluded.
Motion Control
Rope geometry, drive control and active anti-sway reduce residual motion. The performance specification should define allowable sway, positioning tolerance, twistlock confirmation, landing logic and operating behavior under wind.
Automation Scope
Remote or automated RTG operation requires controlled traffic, reliable container identity, communications, safety zoning and exception handling. TOS job data, positioning, cameras, OCR, collision control, recovery modes and acceptance scenarios form one integrated scope.
Pavement and Wheel Loads
Maximum and minimum wheel loads, tyre pressure, dynamic factors, settlement limits, braking cases and storm parking loads are issued for civil coordination.
Steering and Block Change
Straight, cross, pivot or coordinated steering affects turning radius, block-end width, alignment control and the approved transfer route.
Wind and Marine Protection
Operating wind, out-of-service wind, storm travel, anchoring, coating system, enclosure protection and salt-fog exposure require site-specific definition.
Public Fleet Reference
