Double Beam Gantry Crane
Product Overview
Double girder gantry cranes are available in box-type hook and truss-type hook configurations, offered in both single-girder and double-girder designs.
These gantry cranes are designed for loading, unloading, and handling operations in open-air warehouses, stockyards, railway freight terminals, and port terminal cargo areas.
Hook-type gantry cranes can also be fitted with various specialized lifting attachments (lifting magnets, grabs) for specific applications.
When selecting a crane, customers should specify the maximum and minimum working environment temperatures, power supply type, and other technical requirements.
Double girder hook gantry cranes are semi-customized machinery. Parameters such as rail gauge and other dimensions must be determined based on your site conditions and requirements.
Specifications & Models
The specifications of a double girder gantry crane are defined by its lifting capacity, span, and lifting height. Lifting capacity: 20T, 32T, 50T, 60T, 70T, 80T, 90T, 100T, 120T, 200T, 300T, with a maximum of 600 tons. Span: 7M, 8M, 9M, 10M, 12M, 15M, 16M, 17M, 19M, 20M, 21M, 22M, 33M, with a maximum of 50 meters. Lifting height can be designed according to actual application requirements. The above figures represent common parameters; custom design and manufacturing are available based on customer technical specifications.
Performance Features
The double girder gantry crane operates on ground rails. Work duty classifications include A5, A6, A7, and A8. The standard working environment ranges from -25°C to +40°C, with an average temperature over any 24-hour period not exceeding +35°C. These cranes are not suitable for use in flammable or explosive atmospheres, high-humidity environments, or areas with corrosive gases. They are also not intended for handling molten metal or operating in toxic environments. Operation modes include cabin operation and radio remote control operation (wireless, multi-speed joystick). Weatherproofing equipment can be provided upon request. Power supply options include cable reel and conductor rail systems.
Key Advantages of Double Girder Hook Gantry Cranes
- The hook gantry crane features a box-type twin main girders welded structure, providing increased working space and facilitating transport, installation, and maintenance.
- The trolley is powered via a specially profiled rail cable power supply system.
- All components are standardized, serialized, and interchangeable.
- Power supply options for the double girder hook gantry crane include cable reel type (available for left or right mounting) and conductor rail type (available for left or right mounting), selectable by the customer.
- The operator cab offers excellent visibility and is equipped with a joystick console for smooth, stable, and comfortable operation. Fans, heaters, air coolers, air conditioning, and intercom systems can be fitted upon request.
Working Environment
Hook gantry cranes must not be used for lifting flammable, explosive, or corrosive materials, nor operated in corrosive environments. The crane can be manufactured with a single-end cantilever or without cantilever based on customer requirements. Weatherproofing equipment can be provided upon request.

Purchasing Information
The hook gantry crane consists of the bridge structure, trolley travel mechanism, trolley, and electrical equipment. The bridge features a box-type welded structure, and the trolley travel mechanism uses independent drives. All mechanisms can be operated from the control cabin or via wireless remote control. Power supply options are cable and conductor rail; either can be selected when placing an order. When selecting a hook gantry crane, the order specification form must be completed, specifying the minimum and maximum working environment temperatures and the power supply available.
