Roller chain stopper

Roller chain stopper is a safety device commonly used on ships, primarily for securing the anchor chain or mooring lines. Here's a brief introduction to the roller chain stopper:

1. Design: The roller chain stopper is typically made of high-strength metal and features a structure consisting of rollers and a stopper blade. It is usually installed on the ship's deck or hull structure to secure the anchor chain or mooring lines.

2. Function: The primary function of the roller chain stopper is to secure the anchor chain or mooring lines, preventing them from loosening or slipping in the marine environment. It can adjust the tension of the anchor chain or mooring lines through the adjustment of the stopper blade, ensuring the stability of the ship during anchoring or mooring.

3. Installation Location: Roller chain stoppers are typically installed on the ship's foredeck or hull structure, usually near the point where the anchor chain or mooring lines enter the ship, facilitating the securement of the anchor chain or mooring lines.

4. Standards and Regulations: The design and installation of roller chain stoppers must comply with relevant classification society regulations and international maritime standards to ensure their reliability and safety in various marine environments.

In summary, the roller chain stopper is an important safety device on ships, used to secure the anchor chain or mooring lines and ensure the stability and safety of the ship during anchoring or mooring operations.
