JTPB series mine hoist The moving mechanical equipment of the load is drawn by the steel wire rope wound on the drum. It is mainly used for hauling vehicles underground or on the ground, removing pillars of coal mining face and other auxiliary transportation work.
Product features, main uses and scope of application:
This product is suitable for coal mine shaft or inclined shaft to lift coal, materials, lift personnel and lower material equipment, and can also be used for other traction transportation.
When starting the main motor, the motor rotor transmits the power to the high-speed shaft of the reducer through the elastic coupling. After being driven and decelerated by the reducer, the passive shaft of the reducer is transmitted to the main shaft device through the gear coupling. If the rotation direction of the motor is changed continuously, the drum can be wound or the wire rope can be loosened, so that the hoisting container can go up and down periodically in the shaft Sports.
