Problems noted in daily inspection, maintenance and use of steel wire rope for tower lifting
The strength of the wire rope must be regularly checked during use. Generally, a full inspection or strength test must be performed at least six months.

Second, steel wire ropes are strictly forbidden to be overloaded during use, and should not be subjected to impact. When tying or lifting requirements, care must be taken not to make the wire ropes directly in contact with the sharp corners of the fast mouth of the object, and they should be laid at their contact points. Canvas, Sacks, or other linings to prevent damage to the wire rope by the sharp corners of the object, resulting in equipment and life accidents.
Third, during the use of wire ropes, if the length is not enough, the buckle connection must be used, and it is strictly forbidden to use the wire rope head to wear the fine wire rope method to connect the long hanging objects, so as to avoid the resulting shear force.
Fourth, the edge of the roller used for wire rope wear shall not be broken or cut.
Fifth, during the use of steel wire rope, especially steel wire rope in the movement should not be rubbed with other objects, and should not be dragged diagonally with the edge of the steel edge, so as not to cut the steel wire rope, directly affect the service life of steel wire rope.
When using a wire rope on a high-temperature object, insulation measures must be used because the wire rope will be greatly reduced in strength after being subjected to high temperature.
After the wire rope is used for a period of time, it must be lubricated. On the one hand, it can prevent the wire rope from rusting. On the other hand, the wire rope is used during the use process. Sliding friction occurs between the steel wire and the steel wire in the same strand of its sub-rope per share, especially when the wire rope is subjected to bending force. This friction is more stimulated and can be reduced by adding lubricant
