The steel wire rope of mine winch is an important part of connecting lifting container and lifting device to transfer power. Its reliable use is the guarantee of lifting personnel and materials. The steel wire rope is easy to be damaged and is the weak link in the hoisting, so special attention should be paid to it.

The steel wire rope of winch used in coal mine is twisted into rope strands by the number of steel wires, and the bucket elevator is twisted by several strands (generally six strands) along an oil-bearing fiber rope core. In order to control the bending fatigue stress of steel wire rope, the ratio of drum diameter to wire rope diameter specified in regulations should be met. The steel wire rope shall be arranged in order on the drum, and shall be kept stable during operation without jumping or biting.

Attention should be paid to the lubrication of steel wire rope in the process of using. Good lubrication has great influence on prolonging the service life of steel wire rope. Therefore, it is necessary to oil the steel wire rope regularly. Before oiling, the dust and oil on the steel wire rope shall be removed first, and then the oil shall be applied by manual method or oiler method (the steel wire rope passes through the oil cylinder composed of two halves, and hot oil shall be added to the oil cylinder in time with the movement of steel rope).

Because the head of the wire rope is damaged quickly, the head of the wire rope should be cut off regularly. At the same time, it is also necessary to regularly turn around and replace the end connected with the drum and the other end connected with the connecting device, so as to increase the service life of the wire rope. The time limit of cutting and turning should be determined according to the different service conditions of each unit and the damage of wire rope.

The requirements of winch wire rope for coal mine are introduced here. If you have any other questions, please come to consult.
