Today, the manufacturer of bridge cranes in Shandong will share with you the principle and composition of grab cranes?

The grab crane is mainly used in conjunction with bridge cranes, port cranes, and articulated cranes, and is widely used in ports, power plants, docks, chemical industries, etc. to grab various loose accumulations such as ore, coal, slag, etc. for loading, unloading, light stacking, feeding, and other operations.

working principle:

On a double drum articulated vehicle, one set of drums leads a steel wire rope for support, while the other set leads a wire rope for opening and closing. After half opening the grab, it falls onto the object, and the opening and closing steel wire rope is retracted. The steel wire rope pulls the crossbeam to close the two jaw plates, and the bucket is filled with materials. The lifting support steel wire rope lifts the grab bucket, and it is transported to the unloading site by a crane. The support steel wire rope does not move, and the opening and closing rope is loosened to use the grab bucket to open and unload the captured materials.
