TCK Wire Rope Inspection Technology Co., Ltd is a High–Tech Company in researching, manufacturing, spreading and serving non-destructive inspection instruments for ferromagnetic materials. We have the most advanced "weak magnetic" core technology and all the intellectual property of this independently-developed high-tech innovation. TCK wire rope non-destructive and quantitative inspection system is a successful application of the weak magnetic inspection technology in the area of strip ferromagnetic materials. Since we have discovered and mastered the change and movement rules of the space magnetic field vector around the wire rope, and have achieved three innovations in setting new principles of the Vectorial Resultant of the Spatial Magnetic Field, finding the new method of weak magnetic inspection, and inventing a highly sensitive sensor, TCK sensor’s sensitivity is of 250 thousands of times higher than existing technology (Hall’s sensor or induction coil). Our technology is highly sensitive to internal and external flaws like wire rope breakage, corrosion, abrasion and fatigue.we have successfully solved two difficult problems which have puzzled the entire world for over a century in quantitative detection of the rope flaws and fatigue.
