1 Scope

China's national standard for multi-rope winding mine hoists. It specifies the types and basic parameters, the technical requirements, the test methods, the inspection rules and the marking, packaging, transport and storage. A mine hoist is the machine on which a deep shaft depends absolutely: it raises the ore, and it raises and lowers every person who works underground. The multi-rope winding design uses several ropes wound onto a drum in parallel rather than one, and the reason is depth. A single rope must carry the load plus its own weight, and past a certain depth the rope is mostly carrying itself, so the required diameter grows beyond what a drum can practically wind. Dividing the load among several ropes keeps each of them within a sensible size, and it adds redundancy in the one component whose failure is unsurvivable. That is also why the standard's requirements concentrate on the rope attachments, the braking and the overwind protection rather than on the drive.

This standard specifies the multi-rope winding mine hoist type and basic parameters, technical requirements, test methods, inspection rules, signs, bags Loading, transportation and storage. This standard applies to coal (non-explosion-proof), metal mines, non-metallic mineral shaft or inclined shaft lift personnel, materials and equipment used in multi-rope winding Mine hoist (hereinafter referred to as hoist).
