Maintenance and maintenance of wire rope
2024-12-23
Daily inspection:
Because the wire rope not only bears load, fatigue, wear, and the working environment is harsh, so the daily maintenance and inspection in use is very important. The main contents of maintenance and inspection are as follows: 1. Regularly fill the steel wire rope with anti-rust and lubricating grease. 2, regularly remove the surface of the wire rope with dust and other impurities. 3, daily check and record the wear, broken wire, rust, grease, deformation, diameter and other abnormal conditions of the wire rope. 4, the wire rope should be checked before use. When the wear of the wire rope, broken wire, broken strand, rust, stretching, bending, deformation, fatigue, diameter, the degree of rope core exposure, etc. meet the replacement standards stipulated in the relevant regulations, replace the new rope in time. Maintenance precautions: The service life of the wire rope has a great relationship with the use of the method, so it should be used according to the regulations, prohibit dragging, throwing, use is not allowed to overload, is not allowed to make the wire rope acute Angle bending, is not allowed to dramatically change the lifting speed, to avoid impact load; When the steel wire rope has rust and ash scale, brush it with a wire brush and apply oil; | The wire rope is oiled once every 4 months, and the core of the rope is soaked with hot oil (about 50 ° C) when oiled, and then the excess grease is wiped away; The wire rope should be placed in a clean and dry place after being coiled, and should not be stacked overlapping to prevent sprain; The end of the wire rope is fastened with steel wire or welded with low melting point alloy, and it can also be tightened with iron hoop to avoid loose rope head; In use, if there is oil drop extrusion on the surface of the wire rope, it means that the wire rope has been subjected to considerable force, then the load should be stopped, and the inspection should be carried out, and the new wire rope should be replaced if necessary. |
