(2) Manganese phosphating wear-resistant coated wire rope is an upgraded product of various smooth wire ropes. The thickness of manganese phosphating wear-resistant protective coating on steel wire surface must reach 15-30g/m2, and the steel wire rope with phosphating film weight less than 3g/m2 is not manganese phosphating wear-resistant coating. After arrival, the weight of phosphating film should be tested to determine the quality.

(3) The stronger the steel wire rope core, the heavier the specific gravity, the better the supporting force for the outer strands of the steel wire rope, and the better the quality of the steel wire rope.

(4) The material is the grade and strength of steel. The higher the steel grade, the better the quality of wire rope with higher strength.

(5) After the rope is broken, it is slightly loose and the quality is good. The relatively long wire rope in lay length is better than the short wire rope in lay length.

Extended data

The service life of steel wire rope has a great relationship with the method of use, so it should be used according to the regulations, and it is forbidden to drag and throw. It is not allowed to overload, bend the wire rope sharply and change the vertical speed sharply during use, so as to avoid impact.

Wire ropes should be oiled every four months. When refueling, it is best to soak the iron core with hot oil (about 50℃) and then wipe off the excess grease. In use, if there are oil drops on the surface of the steel wire rope, it means that the steel wire rope has been subjected to considerable force. At this point, the load should be stopped, checked, and a new wire rope should be replaced if necessary.

The elevator with compensation chain (rope) in Guiyang, Guizhou Province, with the natural elongation of the traction wire rope, may cause the compensation chain (rope) to mop the floor, bring unnecessary noise, and even damage the support of the compensation chain (rope) in the hoistway in serious cases.
