The JK series explosion-proof mining hoisting winch is specially designed for mines containing explosive gases such as gas and coal dust. It is suitable for vertical shafts, inclined shafts or inclined tunnels in coal mines, metal mines and non-metallic mines. It is used for lifting personnel, hoisting coal, ore, gangue, and lowering materials and equipment. It can also be used in other traction and transportation scenarios with explosion-proof requirements.
Working Principle
The motor transmits the power to the reel wound with the wire rope through the reducer to realize the lifting and lowering of the container, The speed is adjusted through electrical control. The disc brake is braked by hydraulic and electrical control. The machine,electricity, and hydraulic joint control system composed of various transmission sensors and control components realize the monitoring and protection of the whole machine, and realize the information transmission inside and outside the hoist through computer and network technology.
