The grab bridge crane has evolved from the general bridge crane and is suitable for handling bulk materials such as ores, limestone, coal, coke and coke slag in fixed spans indoors or outdoors. When working outdoors, it is equipped with rainproof devices.

This machine operates under heavy-duty duty, and its lifting capacity includes the self-weight of the grab bucket. The entire machine is composed of five parts: box-shaped bridge frame, large vehicle running mechanism, small vehicle, grab bucket and electrical equipment. All mechanisms are operated in the control room (the control room can be made as an insulated type or other special form according to the user's requirements).

The lifting device is a four-rope grab with double drums. This grab has a simple structure and reliable operation. It can be opened and closed at any height. When the size of the material blocks to be lifted is larger than 200mm, a toothed grab should be selected.
