Just as the geocentric theory substituted helicentric theory, in the field of wire rope inspection TCK gives magnetic field vector synthesis new principle to replace the traditional flux leakage magnetic field principle. Independently, TCK invents the Weak magnetism inspection method to replace the traditional strong magnetism inspection method. And the Dou?s element sensor technology substitutes the Hall element and induction coil sensor technology.

Rooted on TCK inspection technology originality and only, TCK weak inspection technology entirely resolved quantitative detecting wire rope various flaws technology problem which other magnetic technology can?t resolved. Realizing wire rope inspection technologies essentially jump from qualitative detection to quantitative detection. Some importance index of inspection result , such as accuracy, stability and repeat, for the first time, really satisfy the on-site demands under different working conditions. TCK non-destructive and quantitative wire rope inspection system can make quantitative testing on the defect of wire ropes in service and evaluate the remaining load capacity and service life of wire rope in the world. So once it began marketing, it attracts world attention.
