Anchor abandonment devices are devices used on ships to abandon anchors in an emergency in case of sudden danger. There are many types of anchor abandonment devices, including simple anchor abandonment devices, spiral anchor abandonment devices, latch anchor abandonment devices, etc. Their main function is to abandon anchors in an emergency under special circumstances when the ship is anchored at sea. If the anchor windlass fails and the anchor cannot be raised in time, it will threaten the safety of the ship. The crew must immediately operate the anchor abandonment device outside the anchor chain locker to unhook the end chain link from the anchor abandonment device to ensure the safe navigation of the ship. Therefore, the anchor abandonment device is a major component in the anchor equipment.
