The two types of equipment belong to safety protection equipment, and whether the equipment is safe and reliable can not be detected without accidents. For ultra-deep vertical shafts with the length of more than 1500 meters to 2000 meters, the requirements cannot be met by adopting the conventional multi-rope friction or single-rope winding type lifting.

For single-rope winding lifting, the safety catcher is a protection device related to life safety, and a test cage which can be used for all kinds of safety catchers is necessary to design.
