Cast Steel Roller Pawl Type Chain Stopper

China JIS F2031 Cast Steel Roller Pawl Type Chain Stopper – Heavy-Duty Anchor Chain Securing System

Professionally engineered to JIS F2031 standards, our Cast Steel Roller Pawl Type Chain Stopper serves as a critical safety component installed between the anchor windlass and hawsepipe. This robust marine device effectively secures anchor chains during mooring operations, transferring anchor and chain forces directly to the vessel structure while significantly reducing operational loads on the windlass system. During navigation, it reliably supports the anchor’s weight and inertial forces, ensuring complete operational safety across all marine conditions.

Product Features & Technical Advantages

Advanced Load Management: Transfers mooring forces to vessel structure, reducing windlass workload by withstanding up to 80% of chain cable’s breaking load
