IntroductionParameters

Multi-rope mining hoist

(The room is located in the wellbore at the top of the tower) and JKMD series of floor friction mine hoist (Engine Room located directly on the ground) two kinds of friction mine hoist according to the layout is divided into JKM series tower friction mine hoist. The enhancement of the friction mine hoist rope ride hanging on the friction wheel, the use of containers increased by the friction of the friction wheel liner. Enhance the both ends of the rope connected to a container, or connect one end of the container, connect the other end a counterweight. Can use smaller wire rope and a smaller diameter friction wheel, and thus the units small size, ease of manufacturing; high-speed, enhance capacity, safety, good. An annual output of more than 1.2 million tons less than 2100 m depth shaft mostly use this hoist.


 Sichuan Coal Group companies produce JKM, JKMD series of friction hoist roll diameter size of 5.5 m, depth of 1500 m.
