Abstract
A device for releasing a life boat or the like from a hoisting cable, said device comprising a lifting members (13) attached to the boat, a hook (15) being pivotably mounted at said lifting member, said hook being openable by a releasing device. The object of the invention is to provide a releasing device for emergency situations when the normal releasing device is not functioning and which should be releasable even when the full weight of the boat loads the hooks. This has been achieved by the fact that the lifting member (13) is displaceable in its longitudinal direction and that a locking device (29) actuatable by an emergency device is arranged for blocking the lifting member from displacement.
