As a high risk component of hoisting, lifting and conveying equipments, wire rope is regarded as the “lifeline” in many industries. However, the safety of in-service wire ropes has always been the “blind spot ”or “source of danger” in equipment management, because of the lack of reliable testing instrumentation. How to detect the deterioration of in-service wire ropes and ensure their safety is an urgent demand for wire rope users. Invention of tck•w® wire rope on-line real-time safety monitoring system has fundamentally changed the backward situation of wire rope inspection management? The delectability of the tck•w® on-line system is much higher for localized flaws (lf) and its precision is much accurate for the loss of metallic cross-sectional area (lma) and rope diameter reduction. It has solved the three problems of wire rope application –“hidden dangers, waste and low efficiency” for oil drilling (repairing) customers and helped wire rope users achieve “safety, economy and efficiency.”it has been recognized as the most advanced wire rope ndt inspection system in the world. Features *making the steel wire rope under a fully controlled and safe condition in operation process. *combining the production process and inspection process into one, which will reduce one process, increase effective operation time and enhance the productivity. *reducing the idling energy consumption of equipment specifically for testing wire rope, and effect of energy saving is obvious. *making the service life of wire rope more effective and proper, saving wire rope replacing time and reduce the cost of wire rope.
