Abstract

The crane hook (2) assembly has a safety cut-out, to switch off the operating mechanism at a given lifting height. The hook holder (3) is attached to the hook lifting chain (9), with an operating unit (4) to trip the cut-off and fitted with at least one passage opening (7,8) for the lifting chain, with a sliding movement between an upper rest position (A) and a lower stop position. At least one elastic spring (10) is between the safety trip and the hook holder.
