ABSTRACT:
A device for disengaging a wire loop or cable loop either when the hook (2) is unloaded or loaded, when, in the first case, only the locking pivot (9) is removed, or, in the second case, the load is moved onto a hydraulic system (8), whereafter the pivot (9) can be removed and disengagement takes place by discharging the pressure from the hydraulic system (8). After disengagement the hook (2) returns by itself to its original position and can instantly be relocked by the pivot (9) for reloading. Additional safety mechanism can be provided if necessary.
