What’s structure of rubber tired gantry cranes?
Common rubber tyred gantry crane usually adopts box type as the steel structure. To reduce whole weight, truss structure is available, but the cost is higher.
According to different supporting ways of legs, the whole structure mainly adopts n shape and u shape. For n shape, its rigidity and flexible legs are n shape. The cross rigidity of two main girders and strength of crane are achieved through the rigidity of cross girder between legs. For u shape, it is achieved through the rigidity of lower girder between legs.
The lifting mechanism adopts wire rope drum or telescopic frame type, thus the trolley often adopts the structure that combines box girder and plate girder. Travelling trolley structure is related to the organization of lifting mechanism and trolley travelling mechanism, it can ensure the mechanism work well and bear the loading. Operation cabin, electric control cabinet, stabilized, festoon cable are all connected to trolley structure.
Auxiliary structure includes escalators, walkways, maintenance platform.
Advantages of rubber tired gantry crane
