摘要

The device for the locking and unlocking of a load grabbing mechanism includes a lever (20) pivot-mounted on a support component (12) and to which is connected a locking component (30) by which the lever can be selectively locked or released. The pivot (32) of the locking component is installed on the free end of the pivoting lever lying opposite its connection (22) to the support component, and is located in proximity to a deflection roller (28) of the cable or chain pull (Z) which initiates the clamping forces on the grabbing jaws (15,45).
