working principle
The electric motor grab itself has a closing mechanism, and it has a variety of styles. It is a standard electric hoist or hoist mounted on the grab as an opening and closing mechanism. The motor grab can be seen as moving the ratio and reel to the grab itself. Since the motor grab is no longer subjected to the upward pulling force of the closed rope like a four-rope grab when it is closed, the grab's own weight all plays a role in digging. Because of its large grabbing capacity, it is most suitable for grabbing ore materials.
