Elevator wire rope to be replaced once a few years

At present, most of the buildings we live in are high-rise buildings, and we have to take elevators up and down every day. then we all know that elevators must be maintained frequently to ensure safety. then we all know that elevatorswire ropeHow often do you change it? Is there any standard regulation? Luoyang Baikte Technology Development Co., Ltd. to tell you!
In fact, the time standard for the use and replacement of elevator wire ropes is not clearly defined. It mainly depends on the use and wear of wire ropes. When there are broken wires or other abnormalities that affect normal use, it is recommended to replace them. In addition, it also depends on how the elevator maintenance contract is signed. Also consider that the amount of elevator operation is not large, which will affect the wear of the wire rope. Generally speaking, affected by factors such as frequent use, load status and whether maintenance is in place, there is no time limit for the elevator traction wire rope to be scrapped. However, there is a scrap standard, GB7588,TSGT7001 stipulates that when one of the following situations occurs, the traction compensation wire rope shall be scrapped:
1. Cage distortion, rope core extrusion, kinking, partial flattening and bending;
2. Broken wires are scattered in the whole wire rope, and the number of broken wires of a single strand in any lay length is greater than 4; Or the broken wires are concentrated in a certain part or one strand of the wire rope, and the total number of broken wires in one lay length is greater than 12 (for the wire rope with 6 strands) or greater than 16 (for the wire rope with 8 strands);
3. The diameter of the worn wire rope is less than 90% of the nominal diameter of the wire rope.
In addition, it is also required that the rope end of the steel wire rope should be fixed reliably, and the connecting parts such as springs, nuts and split pins should not be defective.
In short, the replacement time of the elevator wire rope is not clearly defined, mainly depends on the damaged condition of the rope, which requires a regular maintenance company to be responsible for reasonable use and maintenance, in order to ensure the safe and reliable operation of the elevator and avoid serious accidents.
