Mine winch It is a small winch that we often talk about. It has the characteristics of fast and convenient, and is welcomed by enterprises. This time, it brings you potential safety hazards in the process of work, hoping to ensure safe production for your enterprise. help.
Mine winch is mainly used for hauling coal mine and other auxiliary processing work on the road with inclination angle less than 30 degrees. The motor provides torque to the drum through the reducer, the wire rope is wound on the drum, and the brake device controls the operation and stop to meet the scheduling and processing purposes.
The accidents that are easy to occur in the inclined roadway transportation of mine winch are wire rope fracture accident, or the personnel, dangerous area, collision or interference damage between vehicle and wire rope on the track of vehicle hauled by steel wire rope.
Unsafe behavior of mine winch transportation;
1. In order to save physical strength, illegal trucks will roll or fall from the mine, drag and friction in skip transportation.
Hook workers should immediately stop such violations and send stop and stop signals to the mine winch driver immediately.
2. Overload mining winch transport overload. The winch must be familiar with the performance of the winch, especially the large static tension of the elevator, and estimate the tension generated by various vehicles entering the wire rope track.
In particular, materials that are not often pulled should not be blindly linked together. They need to make it clear to management and be cautious. Overload, or insufficient torque of the material can cause an accident if the brake rope is overloaded.
3. The mine winch is operated by unauthorized personnel.
Due to the mine winch driver on duty can not work after work or other reasons, the work arranged by the group leader is inconspicuous, and the vehicle driver is not arranged in the transportation operation. Therefore, this kind of illegal behavior may occur in the underground transportation operation, unauthorized personnel start the winch illegally.
Such violations can have serious consequences. Unauthorized personnel are not familiar with winch performance. In an emergency, they can't handle it properly. If the inclined roadway transportation operation site is in the hidden danger state, the accident is likely to occur.
4. When leaving the inclined lane, the plug at the top of the slope is not closed.
After the first shift of tilting workers, the crane was asked to close the top of the road. Some careless workers often don't pay attention to the details of their work and do not create reliable hardware transfers for the next shift. In the whole working environment, there is no closed car parking.
