The safety rope is woven from synthetic fibers and is an auxiliary rope for connecting the seat belt. Its function is double protection to ensure safety. The general length is 2 meters, and there are also 2.5 meters, 3 meters, 5 meters, 10 meters and 15 meters. The safety rope of 5 meters or more is also used as a sling.
1, two braided or twisted buckle, rope buckle 200mm;
2. On the basis of the braided or twisted rope buckle, the metal piece is hooked.
1. The texture is soft;
2, different materials, different degrees of wear resistance, if customers want stronger wear resistance, it is recommended to use polymer materials;
3, the tension can be adjusted, one is to choose materials of different texture; the second is to adjust the thickness of the material; the third is the core safety rope, the inner wire rope, the external synthetic fiber;
4, corrosion resistance, materials are Dyneema, Pasteur;
5, high temperature resistance, the material is Kevlar;
6, more varieties, more grades, can be selective.
Safety ropes are usually evaluated for strength in terms of strength, namely tensile strength and impact strength. The national standard requires that the tensile strength (limit tension) of the seat belt and its string members must be greater than the longitudinal tension caused by the weight of the human body in the direction of the fall.
The impact strength of the safety ropes and accessories is required to withstand the impact strength, and must be able to withstand the impact of the human body falling in the direction of the fall. Generally, the magnitude of the impact force is mainly determined by the weight of the faller and the distance of the fall (ie, the impact distance), and the fall distance is closely related to the length of the safety rope lanyard. The lanyard is long, the impact distance is large, and the impact force is also greater. The theory proves that the human body will be injured by the impact of 900kg. Therefore, the length of the safety rope lanyard should be limited to the shortest range while ensuring operational activities.
