Four rope clamshell grab bucket is a kind of lifting equipment with excellent performance, which consists of bucket body, upper bearing beam, lower bearing beam, spreader bar and balance frame. Double flap means that there are two mutually symmetrical bucket bodies. Four-rope means that the work of the grab is controlled by four wire ropes, two of which are hung on the rope guide device (balance frame) on the upper bearing beam and are called support ropes; and the other two are connected with the wire ropes wrapped around the grab pulley block and are called closure ropes.

Four rope clamshell grab bucket is mainly used in conjunction with harbor cranes, deck cranes, ship unloaders and other cranes with two sets of hoisting reels, and is used to grab various bulk cargoes with uniform granularity for loading, unloading and transferring piles of material and other operations, such as grains, coals, cements, sulphur, mineral powders, ore, etc. It is widely used in the fields of harbor, iron and steel plants, power stations and ships.
