The motor transmits power to the drum around which the steel wire rope is wound through a speed reducer, enabling the hoisting and lowering of the container. Speed regulation is achieved through electrical control. The disc brake is actuated by both hydraulic and electrical control. The depth indication of the hoisting container is realized via various position indication systems.
The motor transmits power to the drum around which the steel wire rope is wound through a speed reducer, enabling the hoisting and lowering of the container. Speed regulation is achieved through electrical control. The disc brake is actuated by both hydraulic and electrical control. The depth indication of the hoisting container is realized via various position indication systems. The monitoring and protection of the entire machine are carried out by the mechanical, electrical and hydraulic integrated control system composed of various sensors and control elements. The information transmission both inside and outside the hoist is realized through computer and network technologies.
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, lifting and lowering personnel, as well as lowering materials and equipment. They can also be applied to other traction and transportation tasks.
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".
