Four Rope Double Scoop Marine Grab mechanical Clamshell Grab Bucket
Grab is a special tool for cranes to grab dry bulk cargo. Two or more barrel-shaped flat plates that can be opened and closed are combined to form a container space. When loading, the raft is closed in the material pile, the material is captured in the container space, and the raft is in the pile during unloading. When the upper suspension state is opened, the material is scattered on the pile, and the opening and closing of the seesaw is usually controlled by the rope of the crane hoisting mechanism. Grab operation does not require heavy physical labor, can achieve higher loading and unloading efficiency, and ensures safety. It is the main dry bulk cargo handling tool in the port. According to the type of goods, it can be divided into ore grabbing, coal grabbing, grain grabbing, and wood grabbing.
The four-rope grab is mainly used with bridge or gantry cranes with two sets of lifting drums to grab all kinds of loose deposits and perform operations such as loading, unloading, and transferring materials. Mainly supporting double girder bridge crane or double main girder gantry crane. According to the type of material and user requirements can be designed with teeth, parallel beam opening, underwater operation, and other forms. Because the size of the bucket part of the grab is different, the capacity of the material captured is different, we usually divide the grab into four grades: light, medium, heavy, and super heavy.
