Marine Swivel Type Anchor Releaser

About product

The swivel-type anchor releaser features a compact structure, simple operation, reliable mechanical strength, and durability, ensuring stable performance even under harsh sea conditions. Its core advantage lies in the screw-driven mechanism, which enables precise force adjustment, allowing the clamping body to distribute the anchor chain load evenly and prevent excessive local stress that may cause damage.

  • Screw transmission design allows accurate adjustment of chain link height, enabling secure clamping or quick release.
  • Wide applicable range of anchor chain diameters (12.5–160 mm), meeting the needs of most merchant and engineering vessels.

Product Detail

Ship Swivel Type Anchor Releaser

The screw-type anchor releaser is a key emergency device in ship anchoring systems, primarily used to quickly release the end link of the anchor chain in the event of windlass failure or emergency situations, thereby ensuring vessel safety and navigation security. The main body is typically made of high-quality carbon steel, with surface treatment options such as black paint coating or hot-dip galvanizing, providing excellent corrosion resistance for long-term use in harsh marine salt-spray environments.

  1. Screw-Drive Mechanism: By rotating the handwheel or handle, the screw drives the clamping body (brake jaw) to rotate around the pin shaft, achieving secure locking or quick release of the anchor chain end link. This design offers intuitive operation, even load distribution, and ensures reliable disengagement under tension.
  2. Clamping Body and Slip Hook: The clamping body forms a chain-link passage when closed, ensuring smooth insertion of the chain link and providing stable support when locked. The slip hook fixes the chain end link in place, keeping it secure under load and preventing accidental release.
  3. Operation and Safety: The screw-type anchor releaser disengages through a screw-driven clamping linkage, typically requiring 2–5 manual steps. Although the procedure is relatively detailed, it delivers high reliability and can safely release the anchor chain even under tension.
  4. Application Range: This device is commonly used on naval vessels and certain merchant ships. A typical applicable anchor chain diameter range is 25–60 mm, with customization available to meet specific ship types and emergency anchoring requirements.
