The back column winch adopts the motor work to drive the reel to wrap the wire rope to achieve the purpose of dragging the equipment or articles. For the back winch, the characteristics and advantages of the slow and stable formal back winch, the back winch motor, the drum, Wire rope is the most basic configuration. The use of the back winch will have various indispensable problems with the increase of time. Even the treatment and prevention work are very important for the mining enterprises.
The back winch brake belt is heated or partially overheated, which is a hidden back winch failure. The back winch winch driver may not find the problem for a long time. This is a very serious phenomenon, which will lead to a long time. Serious consequences have caused mine accidents. Be cautious and strictly check!
This time, I will introduce you to the reasons for the heating or local overheating of the back winch brake belt:
Reason one: the brake shoe is too long
Reason two: the brake shoe clearance is too small
The treatment plan is as follows:
Facing the cause of heating or partial overheating of the backing brake brake belt||Reducing the time for placing heavy objects under the long-term brake, the second reason is: adjusting the brake shoe clearance.
Analysis of the causes of the heating of the hydraulic thruster of the second column winch brake device:
Reason one: the oil is not clean
Reason two: long-term operation
Reason three: high viscosity of hydraulic oil
Facing the above reasons, the hydraulic thruster of the winch brake device is heated, and the treatment plan is simple and easy to operate.
The corresponding treatment scheme for the heating of the hydraulic thruster of the back winch brake device is as follows:
 Treatment plan 1: Clean the hydraulic thruster and replace the hydraulic oil
 Solution 2: Strengthen heat dissipation
 Treatment plan 3: Replace low-grade hydraulic oil or transformer oil
Through the above treatment problems for the heating or local overheating of the back winch brake belt, we can see that choosing a good back winch can reduce the error rate of the mining winch.
