The Four rope clamshell mechanical dredging grab :
The four ropes double-flap dredging grab is primarily utilized for underwater channel dredging, desilting, and salvage operations, capable of handling complex materials such as silt, hard clay, iron-plate sand, blasted reefs, and even sunken ships with ease.
1. Operating Principle
The four rope clamshell grab operates through two sets of steel wire ropes (each set consists of two ropes) to achieve its opening, closing, lifting, and lowering movements. One set of ropes serves as support ropes, responsible for maintaining the grab's balance and stability, while the other set functions as opening and closing ropes, controlling the grab's opening and closing actions.
