Roller Knife Chain Brake for Hydraulic Combined Windlass 

The chain stopper is set between the windlass and the anchor cylinder to fix the anchor chain and prevent the anchor chain from slipping out. When mooring, the chain stopper transmits the tension generated by the anchor and the anchor chain to the hull to reduce the load of the windlass and protect the windlass. Bear the anchor's gravity and inertial force when sailing. It is the accessory equipment of the windlass. At present, the chain stopper is large in size, heavy in weight, and lacks a combined structure, which is extremely inconvenient when assembling and moving.
