The average climber always thinks that the pulling force of the climbing rope is an important technical parameter. In fact, for climbing ropes, the maximum pulling force is generally not marked, but the impact force, ductility and the number of drops of the International Board parameter. Here we must first explain the requirements of climbing ropes. We know that the pulling force when the falling object stops falling is far greater than its own weight, and the climber will eventually rely on the pulling force of the climbing rope to stop the falling when falling, so the climbing rope Give the human body a great pulling force, which is an important parameter related to the safety of the climber. UIAA requires that the impact force must not be greater than 12 kN, and the safety belt may break the climber’s waist if it exceeds this tension. The impact force is largely determined by the ductility of climbing ropes. Climbing ropes are widely called power ropes abroad. Only this type of rope can cope with climbing with the possibility of falling. The ductility of this type of rope is generally 6 ~8%.
As we all know, UIAA certified DYNAMIC power rope mainly has two indicators, the first impact and the number of UIAA drops, but most domestic climbers do not understand that there are three indicators that are also the key to choosing a climbing power rope. The three indicators are: anti-cutting index, abrasion resistance index, and water resistance. According to the statistics of domestic climbers, more than 90% of climbing power ropes have been worn out before the UIAA FALLS life span is far from reaching the index requirements. Therefore, wear resistance and water resistance are factors that must be considered when choosing a climbing rope.
