Rubber tyred gantry cane, also called rtg crane (rubber tyred container gantry crane), is a type of gantry lifting equipment. Rubber tired gantry crane is composed of main girder, rigid legs and flexible legs, travelling trolley, lifting mechanism, travelling mechanism, electric system, and operation cabin. According to cantilever, it can be divided into three types, no cantilever type, single cantilever type, and double cantilever type. Rubber tyre gantry crane is widely used for lifting and transporting material in station, wharf, open warehouse yard, construction site, hydropower station, assembly field. AIMIX Group, one of best rubber tyred gantry crane manufacturer, supplies types of cranes with reliable quality and affordable price.
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
First, gantry crane with shield (DMC for short) is mainly used for installation of cutter and shield of shield machine, which is underground trenchless device, and used for lifting of duct piece supporting tunnel during work progress.
Second, professional spreader with 360° rotation is fit for installation of cutter from different angles.
Third, double trolley mechanism is applied for lifting cutter by tandem operation or lifting duct piece by separate operation.
Fourth, exposed gear drive is applied for lifting mechanism to save cost.
