What’s the Multi-rope Friction Hoist?
The multi rope friction hoist is mainly used for lifting coal, minerals, lifting personnel, lowering materials and equipment in vertical shafts of coal, metal and non-metal mines.
It mainly consists of an electric motor, a reducer, friction wheels, a braking system, a depth indicator, a speed measurement and speed limit system, and a control system.
There are several control modes of mine hoist, such as manual, semi-automatic and fully automatic.
With the deepening of mine exploitation and the adoption of centralized lifting methods, multi-rope friction type mine hoists have a promising future. And for this purpose, explore friction liner materials with good wear resistance and high friction coefficient.
The new structure of multi-rope friction winding mine hoist has started spreading to various countries s, and it is of great significance for deep well mining with a lifting height of up to.
How to Solve Hoist Faults?
How To Solve Hoist Faults?
The main reasons for the failure of mine hoists are: bending of the main shaft, abnormal noise from the drum, and heating of the main shaft bearings.
The first method is to adjust the coaxiality and levelness; Prevent load impact and strictly prohibit overloading operation.
The second method is to tighten or replace the connecting bolts; Perform welding reinforcement and anti deformation treatment; Adjust the rope adjustment mechanism.
The third method is to supplement lubricating oil and clear the oil circuit; Clean and replace with qualified grease.
