The electric motor transmits power to the drum winding the wire rope through a reducer, enabling the hoisting and lowering of containers. Speed regulation is achieved via electrical control. The disc brake is hydraulically and electrically controlled. Depth indication of the hoisting container is provided by various position-indicating systems. A combined mechanical,electrical, and hydraulic control system, including sensors and control components, monitors and protects the hoist. Information transfer inside and outside the hoist is realized using computer and network technology.
The JK and 2JK series single-rope winding hoists are mainly used in vertical or inclined shafts of coal, metal, and nonmetalmines for lifting coal, materials, personnel, and lowering equipment or other cargo. They can also be used for other traction and transport applications.
These hoists are designed and manufactured in accordance with:
Q/HBWF003-2016 – Enterprise Standard for Single-rope Winding Mine Hoists
AQ1035-2007 – Safety Inspection Specification for Single-rope Winding Hoists in Coal Mines
GB/T20961-2018 – National Standard for Single-rope Winding Mine Hoists
Coal Mine Safety Regulations
