What are the materials of safety ropes

The safety rope is hand woven with man-made fiber. It is an auxiliary rope used to connect the safety belt. Its function is double maintenance to ensure safety. Generally, the length is two meters, including 2.5 meters, 3 meters, 5 meters, 10 meters and 15 meters. The safety rope above 5 meters is also used as rope. The types of safety ropes include general safety ropes, which are made of cotton fiber and other raw materials. The raw materials of live working safety rope are mulberry silk, waterproof mulberry silk, dimale Gobi and American DuPont silk. The high toughness safety rope is made of dimal Gobi, American DuPont silk and high strength silk. The safety rope is woven with synthetic fiber. It is an auxiliary rope used to connect the safety belt. Its function is double protection to ensure safety. The general length is 2 meters, but also 2.5 meters, 3 meters, 5 meters, 10 meters and 15 meters. The safety rope above 5 meters is also used as the lifting rope.

The diameter of safety rope shall not be less than 13mm, and the twist shall be (8.5 ~ 9) / 100 (flower / mm). The diameter of hanging rope and girth rope shall not be less than 161nin, and the twist shall be 7.5/100 (flower / mm). All hanging ropes for welders must be sleeved.
