The first Chinese technology that wins the OTC award in the past 50 years

TCK.W Wire rope inspection technology has won 2018 American offshore technology conference Spotlight Award on New Technology . TCK.W inspection technology is safe and beneficial. It not only helps to provide the safety monitoring of wire rope in its entire service life but also reduces 90% of the dedicate inspection time by conducting the inspection during production. The reduced inspection time can be used for production, which will highly improve productivity and reduce equipment energy consumption with obvious energy-saving effect. Besides, this system can scientifically prolong the service life of wire rope and reduce the cost of wire rope at the same time. Furthermore, this system can accurately evaluate the defect development trend of wire rope and provide big data quantified evidence for maintenance.

TCK.W Automatic Real-timeOnline Wire Rope Inspection System will revolutionize periodic human visual inspection andbringin-process safety monitoring to its highest statet hrough continuous inspection during operation.

Economic Effect Analysis

Application of TCK.W Wire Rope Online Monitoring System brings considerable economic benefits to Yungang mine. There are four winches in total in Yungang Mine. It saves nearly 1,000,000 kW·h electricity energy and reduces shutdown time for inspection about 973h annually. If all this expensed energy and time are used in production, the mine can additionally produce 304,000 ton raw coal, based on the calculation of 5000 ton/day of raw coal lifting per day of 16 hour.
