It has close relationship with the safety of these fields. However, do you know how to guarantee the safe operation of the rope? Now follow me. Ill show you everything you need to know and want to know about the rope safety.


For a long time, due to the lack of scientific rope test method, all kinds of rope accidents are taking place everyday all over the world, causing heavy loss of property and human lives. 


On May 25, 1995, the No. 9 cable on the Haiyin Bridge of Guangzhou City suddenly broke, causing a great loss of millions of dollars.


On Oct. 3, 1999, in the Maling Scenic Area in Guizhou Province, a broken cable on the ropeway caused a disastrous accident, in which 22 tourists lost their lives, the only survivor being a 2-year-old boy.    


On March 18, 2004, in an accident caused by broken hoist ropesin Tengzhou Dongda Coal Mine, Shandong Province, seven died and 4 seriously wounded.    


On July 17, 2001, an even more catastrophic rope accident took place in a shipbuilding yard in Shanghai, causing 36 people dead, 3 wounded, including well-known professors and experts in shipbuilding. The loss is immeasurable.


According to the statistics of the State Administration of Quality and Technical Supervision, from January to May 2003, the accidents caused by rope break in the coal industry amounted to 215, in which 223 people died.


According to a survey made by a mining bureau of Sichuan Province on the freight ropeway accidents in a period of 15 years, the accidents caused by rope break take 16%, totaling 90 in all, causing 734 hours of outage, which is 24% of the total outage time.
