Marine Dog Type Cable Clenches Anchor Releaser

About product

The dog type cable clenches releaser is a simple-structured and fast-acting emergency anchor release device for ships. Its working principle relies on a transverse latch pin that secures the end link of the anchor chain; in emergency situations, striking the pin handle allows the link to quickly disengage from the pin, thereby achieving the anchor release function. The device is usually installed outside the chain locker or on the deck, and is designed to meet a water pressure sealing requirement of 0.07 MPa, ensuring reliable performance even under harsh sea conditions.

  • Fast response: Once triggered, it can complete disengagement within a few seconds, offering a significant advantage compared to screw-type anchor releasers, which typically require more than 30 seconds.
  • Wide applicability: Primarily used on medium and large vessels such as oil tankers, bulk carriers, and engineering ships, suitable for anchor chain diameters ranging from 52–120 mm.

Product Detail

Ship Dog Type Cable Clenches Anchor Releaser

The Dog Type Cable Clenches Anchor Releaser is an essential emergency device in ship anchoring systems. It is primarily used to quickly release the end link of the anchor chain in the event of windlass failure or other emergencies, ensuring the vessel can safely maneuver to avoid danger. The device secures the chain end link with a transverse latch pin, and in emergency operation, striking the pin handle allows the link to rapidly disengage from the pin, achieving the anchor release function. Its structure is similar to a door latch, with a simple design and fast action. It can be customized according to ship type and operational requirements, providing reliable safety assurance at critical moments.

  • Deck Type: Usually installed on the deck, equipped with a watertight cover, capable of meeting a water pressure sealing requirement of 0.07 MPa, ensuring reliable protection even under harsh sea conditions.

  • Chain Locker Type: Installed inside the chain locker, allowing flexible integration with the windlass and chain system, providing high operational flexibility and safety.
