Abstract

A helicopter load hook has a release mechanism that can be mounted in a fixed position in a housing for controllable identification and release of a swivel movement of a hook. The release mechanism includes a magnetic switch and a drum that can rotate. The release mechanism also includes at least one latching piece, which can be swivelled about a latching piece axis of rotation and at least one force receiver, which can be swivelled about a swivel axis, together with a pin. The pin can be connected with a locking lug on the drum together with a hook follower on the hook, such that an indirect connection between the hook and the drum, or more particularly, the magnetic switch, can be achieved, and any direct contact between the hook and the magnetic switch is eliminated. In the closed position of the hook the pin makes any swivelling movement of the hook impossible.
