The motor transmits power to the drum around which the steel wire rope is wound through a speed reducer, realizing the hoisting and lowering of the container; speed regulation is achieved through electrical control; the disc brake is braked by hydraulic and electrical control; the depth indication of the hoisting container is realized through various position indication systems; the monitoring and protection of the whole machine are realized by the mechanical, electrical and hydraulic combined control system composed of various sensors and control elements; and the information transmission inside and outside the hoist is realized through computer and network technology.

The JK and 2JK series single-rope winding mine hoists are mainly used for hoisting coal and materials in the vertical shafts or inclined shafts of coal mines, metal mines and non-metal mines, raising and lowering personnel, and lowering materials and equipment, etc. They can also be used for other traction and transportation purposes.
The JK and 2JK series products are designed and manufactured in accordance with the industry standard AQ1035-2007 "Safety Inspection Specification for Single-rope Winding Mine Hoists for Coal Mines", the national standard GB/T20961-2018 "Single-rope Winding Mine Hoists", Q/YX006-2020 "Single-rope Winding Mine Hoists", the "Coal Mine Safety Regulations", and GB16423-2020 "Safety Regulations for Metal and Non-metal Mines".
