Application Status of Nondestructive Testing Technology for Elevator Wire Rope

Release time:

2021-05-17

The structural characteristics of the elevator wire rope determines the particularity of the failure. With the increase of the use time of the elevator wire rope, various forms of damage will occur during the use of the elevator wire rope, such as: the reduction of the cross-sectional area due to wear and corrosion. When a certain position of the elevator wire rope fails, the whole wire rope will be scrapped after reaching the scrapping standard. All in all, in the process of use, the elevator wire rope often has the following problems, namely: broken wire, wear, corrosion, deformation, and different forms of damage will also affect each other.

Application Status of Nondestructive Testing Technology for Elevator Wire Rope

　　NDT of Elevator Wire RopeApplication status of technology:

1. Frequent failures of elevator wire ropes

2. Application of foreign elevator wire rope nondestructive testing technology

At present, foreign elevator wire rope detection technology is from the early wire rope broken wire, wear, corrosion and other defects detection to the wire rope LMA, wire rope strength evaluation and wire rope life prediction estimation direction. Some developed countries have adopted guidelines for using non-destructive testing techniques to determine wire ropes, and in the newer international standards, it is clear that the combination of manual inspection and wire rope non-destructive testing can determine the degree of deterioration and LMA of wire ropes.

3. Application of domestic elevator wire rope nondestructive testing technology

In recent years, with the development of science and technology, the domestic research and development of non-destructive testing equipment, has been used in the market. But the use effect is not satisfactory, LMA signal processing is still difficult.

Many years of research and practice make the wire rope nondestructive testing technology has made great development, but this situation and the purpose of wire rope nondestructive testing is still far away. The qualitative detection of some domestic detection companies has been relatively reliable, but due to the diversity and complexity of wire rope damage and the influence of external interference, it is still difficult to quantitatively determine the relationship between the detection signal and wire rope damage.
