The electric hoist bridge crane is composed of four parts: a box shaped bridge, a crane operating mechanism, a small car, and electrical equipment. It uses a fixed electric hoist installed on the small car frame as the lifting mechanism. The small car operation adopts LD type transmission, and the crane operation is divided into LD type transmission and QD type transmission. The structure is simple and lightweight, with the characteristics of small overall height and light self weight, suitable for workplaces such as factories, mines, workshops, and warehouses within the range of medium and small lifting weights. There are three operating modes: ground handle, wireless remote control, and driver's cab. There are two types of cabins: open and closed.
