As a high-risk and key component of cableway equipment, wire rope is regarded as the “lifeline” for the cableway transportation. However, for a long time the rope failure accidents always lurk during the operation of wire ropes due to the lack of scientific and reliable inspection instrumentation. Management departments mostly adopt the methods of visual inspection and periodic replacement of wire ropes to ensure the safety of in-service wire ropes

However Visual inspection only detects external flaws, but cannot detect “major hidden dangers” such as internal broken wires, abrasion, corrosion, fatigue and so on.

Periodic replacement of wire ropes results in huge waste which cannot radically prevent wire rope failure accidents.

Traditional wire rope inspection technology cannot accurately detect the flaws of wire ropes due to its various limitations such as low sensitivity, low repetition rate, influence by speed, “zero drift” and big weight. Therefore the safety of in-service wire ropes has always been the “blind spot” in cableway safety management.

TCK weak magnetism inspection technology successfully solves the difficult problems in the safety inspection of cableway wire rope and provides cableway management departments with reliable method to monitor the safety status of wire ropes, avoid rope failure accidents, scientifically reduce the cost of wire rope replacement and enhance the service efficiency of wire ropes.

To further satisfy the demand of cableway users, TCK has developed Cableway Wire Rope Online Real-time Automatic Inspection System based on the successful development of TCK Portable Wire Rope Testers. Compare to portable wire rope tester, the new system is more advanced in performance and more intelligent in testing process.    

TCK Cableway Wire Rope Online Real-time Automatic Inspection System has high detectability on all kinds of Localized Flaws (LF) including broken wire, abrasion, corrosion, fatigue and etc, and also has accurate resolution in the Loss of Metallic Cross-sectional Area (LMA). It can accurately perform quantitative and positioning inspection on all kinds of flaw and also provide reliable inspection reference for evaluating the residual bearing capacity, safety coefficient and service life of the wire rope.

At present, TCK Wire Rope Online Real-time Automatic Inspection System has been widely used to inspect the important wire ropes in the industries of mining, ports, petroleum, steel mills and others. And it’s playing very important role in eliminating wire rope failure accidents radically.
