ABSTRACT:
Lifting hook having a safety latch (10) arranged in a cavity (11) in the hook, which latch can be swung outwards and which is locked in closed position thereby that, by a spring (22), it is displaced to support, with end surfaces of slots (12), against a safety latch shaft (9). A corner portion (28) and a protruding member (23) thereby prevent a swinging outwards of the safety latch by supporting against an inner wall (18) in the cavity and a recess (25), respectively, in an upper wall (19). To open the hook, the safety latch is pulled downwards against the spring force, so that the corner portion (28) runs free from the inner wall and the safety latch can be swung outwards. The safety latch can be arranged to be lowered automatically when the hook is loaded on the commencement of a lifting operation, a suspension shaft (7) thereby, by being displaced in a slot (8) acting on the protruding member (23) so that the safety latch is released and is lowered by the spring force and locked.
