The subject of this specification is safety detaching hooks for mine shaft conveyances.
According to South African Law1 it is a legal requirement for all winding systems, where the end of the winding rope is fastened to the drum of the winding engine, to be fitted with a safety detaching hook. The main purposes of a safety detaching hook are to detach the winding rope from the conveyance in the event of an overwind and to support the conveyance in the headgear after such an event.
