Types of Ropes used in Rock climbing

There are basically two "types" of ropes, Dynamic and Static. These can be used in a number of applications, depending on their width, length and options. The following will give you an understanding of the different types and options used in most climbing ropes today.

Two Types


Dynamic:

The rope is designed to stretch at a designated percentage given a static load of a designated weight (i.e. 6.5% stretch on static load of 80Kg). The reason these ropes are designed to stretch is to minimize and absorb some of the impact of a fall - imagine taking a 20' fall w/ no stretch, you could snap your back in two! These ropes are used in any/all lead climbing to protect the climber by absorbing the impact of a large fall. This is the standard in rock climbing. These ropes can be used for rappelling, top-roping and hauling gear like it’s cousin, the static rope, but understand that these practices will put more wear and tear on the ropes and cause them to wear out faster.

Static:

Static lines are the opposite of dynamic ropes and market their ability to NOT stretch under load. These are primarily used for rappelling, top-roping and hauling gear, however should NEVER be used for lead climbing
