Several Reasons For Brake Failure Of Mine Dispatch Winch.
1. Overload work, any machinery can not overload work, because the winch for a long time overload operation, machine fever, resulting in winch brake failure;
Solution: Please follow the winch manual and work with rated load.
2 brake belt and brake wheel between the grease, because the Dispatch Winch in the use of the need for lubrication, careless operation, there will be oil between the brake belt and the drum, which will lead to reduced friction, resulting in Dispatch Winch Mine Winch brake failure;
Solution: Wash and dry the contact surface.
3. The contact area between the brake belt and the brake wheel is too small. If the brake belt is deformed or falls into foreign bodies, it will cause the winch brake to fail.
Solution: Adjust the contact area not less than 80%
4. The normal wear of the brake belt, a long time of braking will cause the brake belt wear, when the brake belt wear to a certain extent, the distance between the brake belt and the drum will be more and more large, when the Dispatch Winch winch brake trip, the contact between the brake pad and the drum is not enough, resulting in the Dispatch Winch brake failure.
Solution: Adjust the brake stroke, or replace the brake belt in time.
