HVG MARINE MOORING EQUIPMENT 0095: CB/T 3844-2000 Marine Roller Lever Chain Stopper

Chain stopper is an important mooring device which is used to fix the anchor chain and prevent it slide out when vessels sail or drop anchor. It can reduce the working load to protect the anchor windlass. CB/T 3844-2000 marine roller lever chain stopper is applicable to one-stage, two-stage and three-stage anchor chains in diameter of 42~132mm. Marine lever chain stopper can be welded directly to the deck. Complying with the regulatory requirements of GL, LR, DNV classification societies, roller lever chain stopper can withstand 80% of anchor chain’s minimum breaking load, in which case that the force member cannot be deformed permanently.
