The multi rope friction hoist is mainly composed of an electric motor, a reducer, friction wheels, a braking system, a depth indicator, a speed limit system, and a control system. Using AC or DC motor drive. When using a low-speed motor, a reducer is not needed. The motor is directly connected to the drum spindle, or the motor rotor is installed at the end of the drum spindle. When the transmission power is high, two or four electric motors can be used to drive simultaneously. The total power of a hoist has reached 11600 kilowatts. The braking system is an important device to ensure the safe operation of the hoist. In case of emergency, the braking system should generate two-stage safety braking through a hydraulic system with adjustable braking torque to ensure timely parking of the hoist without excessive braking. The braking system of an AC motor-driven hoist should also have sensitive adjustable braking torque performance to accurately control the operating speed of the hoist near the parking point.

There are several control methods for mine hoists, including manual, semi-automatic, and fully automatic.

With the depth of mining and the adoption of centralized lifting methods, multi rope friction mine hoists have great development prospects. And explore friction lining materials with good wear resistance and high friction coefficient for this purpose; The new structure of multi rope winding mine hoist has begun to be used in some areas, which is of great significance for lifting deep mines with high heights.
