Heavy-Duty Four Rope Double Petal Grab Bucket for Cranes
Product Introduction
The four-rope clamshell grab is a lifting equipment used for grasping and transporting loose materials (such as ores, coal, sand, and gravel). It is usually controlled by two pairs of steel wires, with one pair used for lifting the grab and the other pair for opening and closing the clamshell of the grab. Through different combinations of the actions of the steel wires, the grab can perform the functions of grasping and discharging materials. It has the characteristics of high grasping force and high working efficiency, and is widely used in material handling operations in ports, mines, metallurgy and other industries.
