      12MM static rope
      Static Rope technique (SRT), which has been used in tunnel excavation and rescue, is often used in high-speed downhill, and can be used as top rope protection in rock climbing.
            The static rope is designed to have as little elasticity as possible so that it can hardly absorb the impact; the ductility is much lower than that of the power cord, which is usually only about 3% ductility.
      In the event of a fall, the static rope like a cable, like all the impact directly to the protection system and off, in which case even a very short rush will have a very big impact on the system.
            In addition to low extension rate, the advantages of static rope is also reflected in the rough wear-resistant rope Shengpi and strong resistance. Put aside the power of the buffer capacity of the fall of the fall, the same diameter of the static rope than the power cord to be durable and a lot, and the price is more low, so the more widely used daily.
            The diameter of the static rope carried during rock climbing is usually between 9 mm and 11 mm, and is usually suitable for raising, lowering and using pulleys. The smaller rope is the best choice for climbing mountains, because the main consideration is the problem of mountain climbing weight.
            CEN certification of the static rope: static rope must have a main color coverage of 80%, and the entire rope can not exceed two kinds of secondary color. The power cord is colorful, with a variety of colors are intertwined with each other.
