In order to meet the needs of customers from all over the world, our factory has introduced a number of four stock rope machines from Germany. it is welcome by the customers inland and overseas. Our factory is just 500 miles to Shanghai sea port .fast delivery can be made. We offer timely custom declare and clear.
Power cord: main rope (power cord) is the core of the whole rock climbing protection system, the design criterion of dynamic rope UIAA standards: is a 80 kg of climber off when falling coefficient of 2, the impact of the on its own no more than 12 kn (force limits of the human body, and the experiment on the surface of the human body can withstand the impact of the 12 kn) in a short time, and to realize this purpose is done by the elasticity of the main line, power cord like a bungee cord to absorb a sudden impulse. All other equipment is designed around this premise. Long rope can extend more, absorb more energy, which is why falling coefficient of the same four meters off and 20 meters loss produced by the wallop is as big as.
Static rope: traditional use in the hole, rescue, but now in the high speed drop is often used, even in the climbing museum can be used as the top rope protection; The static rope is designed to be as small as possible, so it absorbs little impact. Still, static rope is not as perfect as the power line, so the elasticity of static rope produced by different manufacturers, different countries and regions may vary greatly. The static rope, like a steel cable, passes all of the impact directly to the protective system and the detached, in which case even a very short crash can have a very large impact on the system. Rope and sling as static rope, they also have no ductility, can be seen in the falling coefficient section when using a static line protection off the impact can be made by sling, seat belts, chains, such as equipment failure, the impact of the more dangerous is such a big waist fractures can directly make off. Under the protection of static ropes, a loss of 1.2 m may cause serious damage to the shed and even endanger the safety of life.
