The four-rope orange peel grab has two support ropes and two opening and closing ropes, which are wound around the drum of the crane support mechanism and the opening and closing mechanism. The four-rope grab is reliable, easy to operate and has high productivity. Because of the use of double support rope and double opening and closing rope, the four-rope grab has a greater total weight, and is widely used in the loading and unloading of coal, ore, grain, fertilizer, wood, wood chips, bread iron and other materials as well as port dredging operations.
