Ship Casting Bar Type Anchor Chain Stopper

About product

The anchor chain stopper is a critical safety device in a ship’s anchoring system. It secures the anchor chain using a pawl or locking mechanism, effectively bearing chain tension up to 80% of the chain’s minimum breaking load, preventing the chain from slipping or striking the hull during tides, rough seas, or ship operations, thereby ensuring safe and reliable anchoring.

Our main load-bearing frame is made of manganese–vanadium alloy cast steel, offering high strength, excellent toughness, and outstanding impact resistance, enabling long-term stable operation even under harsh sea conditions. The contact surfaces of the pawl and anchor chain are wear-resistant, extending service life while minimizing chain abrasion.

Product Detail

Marine Casting Bar Type Anchor Chain Stopper

The ship anchor chain stopper is widely used on various vessels, including oil tankers, container ships, bulk carriers, engineering ships, and offshore platforms. Whether anchoring in port or under harsh deep-sea conditions, it provides reliable mooring safety and security for ships.

  • Knife Plate: Treated with a chromium alloy surface penetration process, with a wear-resistant layer depth of ≥1.5mm. It maintains stable performance under frequent operation or heavy load conditions, significantly extending service life.
  • Pressure Pin Shaft: As a core load-bearing component, it withstands the instantaneous impact forces of the anchor chain. Each shaft undergoes X-ray flaw detection to ensure no cracks, pores, or internal defects, thereby guaranteeing overall safety.
  • Adjusting Screw: Manufactured from 304 stainless steel, it offers excellent corrosion resistance. Combined with an anti-rotation flange nut, it ensures reliable locking even in marine salt spray environments.
  • Locking Structure: Can be flexibly adjusted according to anchor chain specifications, ensuring high compatibility with chain pitch and diameter, and enhancing holding capacity.
  • Easy Maintenance: Key components feature a replaceable design, reducing maintenance cycles and lowering vessel downtime and repair costs.
