Grab bucket is used with crane as a special tool for crane to grab dry bulk goods.
The grab bucket consists of two or more bucket shaped jaw plates which can be opened and closed together to form a holding space. When loading, the jaw plate is closed in the material pile, and the material is caught into the material space. When unloading, the jaw plate is opened in the state of hanging on the material pile, and the materials are scattered on the material pile. The opening and closing of jaw plate are generally controlled by the steel wire rope of the crane lifting mechanism.
