Product purposes  

 
 

 

The multi-rope friction hoist mainly consists of motor, reducer, friction wheel, brake system, depth indicator, speed limit system and control system. Adopt ac or dc motor

drive. Use low speed motor without reducer, the motor is directly connected to the main shaft of the drum, or the motor rotor is installed at the end of the main shaft of the

drum. When the transmission power is large, two or four motors can be used simultaneously. The total power of a hoist has reached 11,600 kw. The braking system is an

important device to ensure the safe operation of the hoist. In case of emergency, the braking system shall produce two levels of safety braking through the hydraulic

system which can adjust the braking torque, so as to ensure that the hoist can stop without braking. Ac motor driven hoist, its braking system has to have the sensitive

braking torque adjustable performance, to control the speed of the lifting machine at the approaching stop point.


The control mode of mine hoist is manual, semi-automatic and automatic.

 

With the depth of mine mining and the use of intensive lifting, multi-rope friction-type mine hoist has a great future. The friction pad material with good wear resistance

and high friction coefficient is explored. The new structure of multi-rope winding mine hoist has been used in some countries, which is important for improving deep well

mining.
