The invention concerns a load torque lock for automatically locking load-side torques in the case of a decrease or cessation of a drive-side torque having a housing (11) fixed to a frame, a locking ring (17) permanently connected to it and a locking body (17) cooperating with it and revolving on the drive side, whose locking means (19, 20), on the one hand, clamp on the locking ring (17) with the occurrence of a load torque by swiveling the locking body (17) by means of locking elements (27, 28) of the output shaft (15) and, on the other hand, release from the locking ring (17) by swiveling the locking body (17) back by means of driving elements (23, 24) of the drive shaft (14). To avoid undesired friction or defective jamming of the locking means (19, 20) on the locking ring (18) by the centrifugal forces of the locking body (17) it is embodied in such a way that its mass center of gravity (M) lies in the area of the rotational axis of the drive shaft and the output shaft that are aligned with one another.
