Mountaineering equipment. Points between the main rope and auxiliary rope two. The main rope length of 60 - 100 meters, about 10 mm in diameter, the weight per meter required in the 0.08 kg, tensile strength requirements of not less than 1800 kg. In the past more use of jute production, has recently been converted to nylon fiber as raw materials. Another diameter of 8 - 9 mm main rope, 0.06 kg per meter weight, tensile strength is not less than 1600 kg, for climbing steep rock.
Auxiliary rope length according to the activities of the region requirements, no uniform specifications, rope diameter of 6 - 7 mm, weight per meter does not exceed 0.04 kg, tensile strength of not less than 1,200 kg, the same raw materials with the main rope, For self-protection and the use of a variety of auxiliary knots on the main rope for protection, as well as rope bridge crossing the river, with traction rope bridge transport materials.
As we all know, UIAA certification DYNAMIC power cord has two main indicators, the first impact force (IMPACT FORCE) and UIAA drop number (UIAA FALLS), but most of the domestic climbers do not understand there are three indicators is the key to choose mountaineering power rope. These three indicators are: anti-cutting index, wear index, water resistance. According to the statistics of the domestic climbers, more than 90% of the climbing power rope is still far from the target requirements UIAA FALLS life has been worn epidermis. Therefore, the choice of climbing rope wear resistance and water resistance must be considered factors.
