Crane is a special tool for grabbing dry and bulk goods. The container space is composed of two or more bucket shaped jaw plates that can be opened and closed. When loading, the jaw plate is closed in the material pile, and the materials are grabbed into the container space. When unloading, the jaw plate is opened when the material pile is suspended, and the materials are scattered on the material pile. The opening and closing of the jaw plate is generally controlled by the steel wire rope of the lifting mechanism of the crane. Grapple operation has no heavy physical labor, which can achieve high loading and unloading efficiency and ensure safety. It is the main dry bulk cargo loading and unloading tool in the port. According to the type of operation goods, it can be divided into ore grab, coal grab, grain grab, wood grab, etc.

The remote control grab is a novel grab which is used to control the opening of a single cable crane through a wireless remote control transmitter. It does not need external energy. It can automatically close with the lifting of the hook on the pile, and can automatically open at any position in the air and stop at any time. There is a storage battery inside the grab, which controls the opening and closing of the grab by controlling the opening and closing of the solenoid valve. The grab does not need any other power supply, which is green. As a new invention of mechatronics, this grab is very popular with users. Its birth rewrites the history of low efficiency of single rope grab in the lifting and transportation industry. The remote control grab is generally composed of upper bearing beam assembly, sliding seat assembly, lower bearing beam assembly, bucket body, strut and oil cylinder. Among them, there are pulley blocks connected with the crane in the upper bearing beam assembly and sliding seat assembly, and the cylinder and piston rod of the oil cylinder are respectively connected with the lower bearing beam assembly and sliding seat assembly. The sliding seat can slide up and down under the action of the crane, driving the lower bearing beam to lift together, thus driving the grab to close; Through the remote control, the lower bearing beam and the sliding seat are separated, so as to control the opening of the grab.

Dredging grab is a kind of grab used for underwater operation, which mainly deals with underwater mud, hard clay, sunken ships and rocks.
