Double girder gantry crane mainly includes crane trolley, crane traveling mechanism, electrics, gantry frame (consisting of main beams, support legs, end beams, ground beams, walkway railing, trolley track, limit installation and cab installation) and so on. This kind of crane is usually used to lift large and heavy items on various occasions.
Classifications of Double Girder Gantry Crane
1. AQ-MG type double girder gantry crane: this types of gantry crane can adopt box type or truss type, that is to say there is double girder box type gantry crane and double girder truss type gantry crane, and the cranes can be with or without cantilever as needed. According to the shape of the legs, the crane can be classified into AQ-MGA type double girder crane and AQ-MGU type double girder crane. Customers can choose the crane with different designs and configurations according to the specific needs. The lifting capacity of the crane is usually in the range of 5-320 ton, its span is from 18 to 35 meters, lifting height is within 6-18m, and its working duty is A5 or A6.

AQ-MGA double girder gantry crane parameters:
- Lifting Capacity: 5t~500t
- Span Length: 18~35m
- Lifting Height: 6~18m
- Lifting Speed: 1.5~11.5m/min
- Trolley Traveling Speed: 10~40.1m/min
- Crane Traveling Speed: 16~50m/min

- Crane Traveling Speed: 37.7~40.1m/min
- Working Class: A3-A6
- Provide Custom Option
3. AQ-RTG type double girder gantry crane: AQ-RTG crane is a kind of mobile gantry crane and it has wide application because of its mobility. This type of crane is available with the span between five to eight container wider and with the lifting height from one over three to one over six containers high.

Rubber tyred gantry crane parameters:
- Lifting Capacity: 10t~50t
- Span Length: 18~35m
- Lifting Height: 6~18m
- Lifting Speed: 5.9~13.3m/min
- Trolley Traveling Speed: 31.3~40.1m/min
- Crane Traveling Speed: 40.1~44m/min
- Working Class: A5-A6
- Provide Custom Option
4. AQ-RMG type double girder gantry crane: this crane refers to rail mounted gantry crane applied to lift and transport containers from one location to another in port or pier. It has fast traveling speed and high work duty.

Rail mounted gantry crane parameters:
- Lifting Capacity: 30t~50t
- Span Length: 18~35m
- Lifting Height: 12.3~21m
- Lifting Speed: 9.2~12.5m/min
- Trolley Traveling Speed: 45~56m/min
- Crane Traveling Speed: 42~50m/min
- Working Class: A6-A8
- Provide Custom Option
Features of Double Girder Gantry Crane
- Our double beam gantry crane has large lifting capacity and wide application on various different occasions, such as used in port, shipyard, construction site, pier, power plants and other materials yards;
- The crane mainly consists of four parts, and they are girder structure, trolley traveling mechanism, crane traveling mechanism and electric device. The girders and frame are welded with advanced welding technology; the crane has light dead weight and strong rigidity;
- The lifting mechanism of the crane is electric trolley, it can adopt hook and other lifting tools to lift and transfer different heavy loads;
- Our double girder gantry crane has two types of conductive forms: cable and slip line, and the slip line form is usually first recommended for the crane;
- The electric parts of the crane adopts famous brand, for example Siemens. Our gantry cranes use top quality materials and famous-brand crane motors to make sure they work reliably and efficiently without failure during material handling process;
- Our gantry cranes have various safety protections: anti-collision system, overload protection device, emergency stop device, lifting height limit switch, buffers and so on. All these protection devices ensure the safe and reliable work of the cranes.
- Our double girder gantry cranes have very reasonable and competitive price;
- The cranes are easy to install and operate, and needs simple maintenance.
