Cantilever gantry crane refers to a gantry crane or semi gantry crane in which the main girders or trusses extend transversely beyond the gantry crane runway on one side or both sides of the crane. For single girder gantry crane with cantilever, there is no need to equip the saddle with the crane; however as for double girder gantry crane with cantilevers, it is needed to equip saddles with the crane to ensure the safe and reliable work of the crane. Cantilever crane is widely used nowadays and it can be with one or two cantilevers as needed.
Types of Cantilever Gantry Crane
Cantilever crane is widely used on many different work occasions and it can be classified into different types as follows:
- The cantilever gantry crane is sorted according to structure type, there are mainly truss type structure cantilever crane and box type structure cantilever crane. Truss gantry crane is more suitable for windy workplace and it is with low cost and easy to install, move and maintain; box type gantry crane can be used for long time and has strong structure to ensure its reliable and efficient work;
Single girder cantilever gantry crane parameters:
- Lifting Capacity: 3t~20t
- Span Length: 8~35m
- Lifting Height: 6~18m
- Lifting Speed: 0.33~8m/min
- Trolley Traveling Speed: 20m/min
- Crane Traveling Speed: 20m/min
- Working Class: A3, A4
- Provide Custom Option
Single girder truss gantry crane with cantilever parameters:
- Lifting Capacity: 3t~20t
- Span Length: 8~35m
- Lifting Height: 6~18m
- Lifting Speed: 0.33~8m/min
- Trolley Traveling Speed: 14~20m/min
- Crane Traveling Speed: 20m/min
- Working Class: A3-A4
- Provide Custom Option
- The cantilever crane is sorted according to girder quantity, there are single girder gantry crane and double girder gantry crane with cantilever. Saddle is not needed for single girder crane even if the crane has cantilever, however, the double girder gantry crane needs to have saddle when the crane has cantilever. These two types of cranes are widely used for heavy load lifting and transporting and they can greatly save work labor and improve work efficiency; for U model double girder gantry crane with cantilevers, there is no need to set saddles on the crane because of its structure. Semi gantry crane is generally used on the occasions without enough space. Clients can adopt suitable gantry cranes to meet their different work needs.
Single girder L-type cantilever gantry crane parameters:
- Lifting Capacity: 5t~50t
- Span Length: 18~35m
- Lifting Height: 6~12m
- Lifting Speed: 5.9~11.2m/min
- Trolley Traveling Speed: 36.6~39.7m/min
- Crane Traveling Speed: 39.7~48.2m/min
- Working Class: A3-A5
- Provide Custom Option
AQ-MGA gantry crane with cantilever 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
- Working Class: A3-A7
- Provide Custom Option
AQ-MGU gantry crane with cantilever 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
- There are also gantry crane with one cantilever on one end of the crane and gantry crane with two cantilevers on both sides of the crane. The cantilever gantry crane can adopt one or more hoists or trolleys to do the lifting and transporting work, different cranes can bear different loads and the weight of the materials should not be heavier than the cranes’ lifting capacities.
Single girder crane with one cantilever parameters:
- Lifting Capacity: 3t~20t
- Span Length: 8~35m
- Lifting Height: 6~18m
- Lifting Speed: 0.33~8m/min
- Trolley Traveling Speed: 20m/min
- Crane Traveling Speed: 20m/min
- Working Class: A3, A4
- Provide Custom Option
