Due to the influence of factors such as the frequency of use, load status and whether the maintenance is in place, there is no time limit for the elevator traction wire rope to be scrapped.
However, there are scrapping standards. GB7588.TSGT7001 stipulates that:
The traction compensation wire rope shall be scrapped in any of the following cases:
(1) Cage distortion occurs, the rope core is extruded and twisted, and some parts are flattened and bent;
(2) Broken wires are scattered in the whole wire rope, and the number of broken wires in a single strand within any lay length is more than 4; Or the total number of broken wires is more than 12 (for 6 strands) or more than 16 (for 8 strands
(3) The diameter of the worn wire rope is less than 90% of the rope diameter.
Therefore, the reasonable steel wire rope product structure can appropriately extend the service life of the elevator
