How often does the elevator wire rope need to be replaced?
2024-01-09
Now we live in most of the buildings are high-rise, every day to take the elevator up and down, then we all know that electricity must be regular maintenance to ensure safety, that we know exactly how long the elevator wire rope for a change?
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. The Housing Reform Commission once suggested that the elevator should be repaired in three years and overhauled in five years. But it didn't say it had to be carried out, just a suggestion.
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 are scrapping standards, GB7588 and TSG T7001, which stipulate that the traction compensation wire rope shall be scrapped when one of the following situations occurs:
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 professional 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. If you use the Tester elevator wire rope flaw detector, it will be safer. You don't have to worry about the degree of wear and the safety factor of the wire rope. You can grasp the situation of the elevator wire rope at any time through the detection to ensure the safety of the occupants.
