Ship chain stopper

for shipbuildingfor offshore platforms

Overview
The cast-steel bar-type chain stopper is the primary device used to control and hold the anchor chain on vessels. The stopper engages the chain by passing a bar vertically through the guide channel and a chain link, providing a direct mechanical hold with a simple structure and straightforward operation.

Key points

• Controls and secures the anchor chain to prevent unintended movement while anchoring or when the chain is fastened.
• Main designs: bar type and screw type; bar type is mechanically simpler and quicker to operate.
• Select the appropriate model based on anchor chain diameter and the cable test/breaking load.

Data

• Refer to the product parameter chart on the product page for detailed dimensions and load ratings.
• Typical applicable chain diameter range: 12.5–68 mm (variant by manufacturer and shipbuilding practice).

Application

• Used in shipbuilding and marine applications to stop and secure anchor chains on vessels and offshore units.
• Bar-type operation: insert the bar through the guide channel to lock a vertical chain link, offering a reliable mechanical hold for anchoring operations.
