Since 2009, after more than half a year's research and development, we have developed a guide rail type fall arrest device with high strength, simple installation, convenient operation, reliable locking and small impact force . The product is composed of tower guide rail, anti falling device, steering gear, connector, connecting rope and safety belt, which can effectively guarantee the personal safety of tower working at heights.

After many trials, explorations and practical applications, the fall arrest device is reasonable in design, has its own characteristics and innovation, and has obtained seven patents. The product has also passed the new product technology appraisal of Zhejiang Electric Power Industry Bureau and has obtained the registration of scientific and technological achievements in Zhejiang Province. At present, it has been included in the bidding project of State Grid.
