JKMD type multi-rope friction hoist
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.
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 nsmission power is large, two or four motors can be used simultaneously. The total power of a hoist has reached 11,600 kw. The raking 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 able 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.
