Grab bucket is a special tool for cranes to grab dry bulk cargo. It consists of two or more bucket jaw plates which can be opened and closed together to form a space for holding material.
When loading, the jaw plate is closed in the material heap, and the material is grabbed into the space for holding material. When unloading, the jaw plate opens in the suspension state on the material heap, and the material is scattered on the material heap. The opening and closing of the jaw plate is generally controlled by the wire rope of the lifting mechanism of the crane. Grab is the main dry bulk cargo loading and unloading tool in port, which has no heavy manual labor and can achieve higher loading and unloading efficiency and ensure safety
