Overview
A double girder gantry crane uses two main girders supported by gantry legs, with the crane travelling on ground-mounted rails or wheels according to the selected design. It is used for material handling in industrial yards, manufacturing facilities, construction sites and other areas where a suitable ground-running crane system is required. The double girder arrangement can be considered for projects requiring particular lifting capacities, spans, hook heights or hoisting configurations. The suitable design depends on the load, working duty, site layout, lifting mechanism and operating conditions rather than capacity alone.

Types of Double Girder Gantry Crane
Double girder gantry cranes are available in different structural designs. The choice depends on the required load, span, lifting height, available clearance, travel arrangement and operating environment.
A-Type Double Girder Gantry Crane
The A type double girder gantry crane has a classic A frame structure with two inclined legs supporting the main girders. This is one of the most common and versatile designs. It provides strong stability and can handle medium to heavy loads in open yards or warehouses. You will find it easy to install and maintain because of its simple structure. This type works well for general material handling, especially when you need reliable performance and flexible operation across different working conditions.
- Lifting capacity:1-500 tons
- Lifting height:According your demands
- Span:12-35 m
- Working temperature:-20-+40 ℃
- Working class:A3–A6
Truss Double Girder Gantry Crane
A truss double girder gantry crane uses an open truss structure rather than conventional solid-web girders. Depending on the design, the truss arrangement can reduce structural weight and exposed surface area while providing the strength required for the specified load and span. This type can be considered for outdoor lifting projects, including yards and construction-related applications. Wind loads, structural deflection, lifting capacity and operating conditions must be checked during engineering review. However, the truss structure alone does not establish that a crane is suitable for every high-wind site.
- Lifting capacity: 5–100 tons
- Span: 12–40 m
- Lifting height: Custom configuration
- Reference working class: A5–A6
- Working temperature: −20°C to +40°C, subject to the selected configuration
U-Type Double Girder Gantry Crane
The U-type double girder gantry crane uses a leg arrangement designed to provide clearance beneath the main girders. This layout can be useful when large loads, vehicles or other equipment need to pass through the working area below the crane. When selecting this design, confirm the clear distance between the legs, available hook height, load dimensions, required span and vehicle access needs. These dimensions determine whether the layout is suitable for the intended operation.
- Lifting capacity: 10–50 tons
- Span: 18–35 m
- Lifting height: 6–18 m
- Reference working class: A5
- Working temperature: −20°C to +40°C, subject to the selected configuration
Double Girder Semi-Gantry Crane
A double girder semi-gantry crane has one side running on a ground-level rail while the other travels on an elevated runway. This arrangement may suit a facility where one side of the lifting area can use an existing or purpose-built elevated runway and the other side has a suitable ground rail. Before selecting this design, confirm the building or runway structure, rail positions, available clearance, lifting coverage and required ground-level travel path. Whether it reduces construction cost depends on the existing structure and the overall installation scope.

Container-Handling Gantry Cranes: RMG and RTG
Container-handling gantry cranes are designed around container lifting and yard operations. Rail-mounted gantry cranes (RMG) travel along fixed rails, while rubber-tyred gantry cranes (RTG) travel on tyres. The two types therefore have different site layouts, travel arrangements and operating considerations. Container cranes may use specialized spreaders and control systems based on the container sizes, lifting requirements and yard layout. Capacity, span, lifting height and working duty should be reviewed for the specific model rather than assumed to be identical across the RMG and RTG categories.
How to Choose a Double Girder Gantry Crane
The crane structure should match the load, working environment and site layout. Before selecting a configuration, review the following factors.
1. Lifting Capacity and Load Characteristics
Confirm the rated capacity and the type of load to be lifted. If the project involves unusual load dimensions, a lifting attachment or a specific lifting arrangement, include those requirements in the technical review.
2. Span and Lifting Height
The span determines the distance between the crane's supporting runways, while the required lifting height affects the overall crane arrangement. Available ground clearance, required hook approach and access beneath the crane should also be considered.
3. Working Duty
Working duty should reflect the expected lifting frequency, operating hours, load spectrum and intended service conditions. The appropriate working class must be confirmed according to the applicable design requirements rather than selected by capacity alone.
4. Hoisting and Travelling Equipment
Depending on the capacity and design, a double girder gantry crane may use an electric hoist or an open winch arrangement. Lifting speed, trolley travel, crane travel, controls and required attachments should be specified for the application.
5. Outdoor Conditions
For outdoor cranes, confirm wind loads, rain exposure, ambient temperature, corrosion protection, power arrangements and any required wind-monitoring or rail-clamping equipment. The suitable provisions depend on the crane design and the site conditions.
Double Girder Gantry Crane Features
- Two main girders: Support the selected lifting trolley or hoisting arrangement.
- Project-specific configuration: Capacity, span, lifting height and travel layout can be evaluated against the application.
- Flexible lifting equipment: Hoisting and travelling arrangements depend on the model and required duty.
- Application-based design: Structural layout, electrical equipment and environmental provisions should be selected according to the intended operating conditions.
- Defined supply scope: The quotation should identify the crane, lifting mechanism and any included tracks, accessories or site services.

Double Girder Gantry Crane vs. Single Girder Gantry Crane
A single girder gantry crane uses one main girder, while a double girder design uses two girders to support the selected lifting arrangement. The appropriate configuration depends on the required capacity, span, lifting height, working duty and overall installation requirements.
| Selection Factor | Single Girder Gantry Crane | Double Girder Gantry Crane |
|---|---|---|
| Main structure | One main girder | Two main girders |
| Lifting arrangement | Selected hoist or trolley configuration | Selected hoist or lifting trolley/crab arrangement |
| Typical selection factors | General lifting requirements, capacity, span and duty | Required capacity, span, hook height, hoisting layout and duty |
| Project review | Confirm whether the selected design meets the specification | Confirm the structural and hoisting requirements for the selected design |
A double girder crane is not automatically the better option for every project. Compare the specified crane configurations and total supply scope to determine which arrangement fits your lifting task and installation conditions.
