The Four rope clamshell mechanical grab :
The four rope double-scoop grab is widely used in various settings such as docks, steel plants, power plants, ships, and bulk cargo storage yards. Its characteristics of high efficiency, stability, and strong adaptability make it one of the important tools in the field of bulk cargo handling.
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.
