JKM type multi-rope friction hoist

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.
