FOR CRANES WITH SUSPENSION- AND CLOSING ROPES
The rope grab is operated on a crane with two hoisting drums. These are the closing rope drum and the suspension rope drum. The grab is hanging on the suspension rope. Opening and closing of the grab shells is done by the closing ropes and the integrated pulley block. (Closing ropes are redirected multiple times through rope pulleys)
According to the quantity of closing and suspension ropes, there is a distinction between single-line, double-rope or four-rope grabs.
The rope grab gains the force for closing and gathering the material through its deadweight, the lever ratio and the reeving of the pulley block.
