Ice Climbing Ropes - Types
Climbing ropes are made from lengthy twisted fibers and a woven fiber placed as an external sheath. The tensile strength of the rope comes from the core while its protection is provided by the external sheath.
There are different types of ropes used in Ice Climbing. The most common of which are the single ropes which are used for most conditions. Nevertheless, these can only be used when climbing routes that extend to a half rope length high, entailing rappelling and lowering. This rope type is advantageous because of its simple rope handling.
Another climbing rope type is the twin ropes which are suited for alpine climbing. Twin ropes have the highest safety margin and permit full length rappels. As the name implies, twin ropes are used in pairs. They are joined together into each protection piece similar to the single rope technique. The use of two ropes builds up the strength, and reinforces the ropes from getting sliced by sharp edges corollary, increasing safety of the climber.
Lastly, half or double ropes provide standard safety if used as a pair. When using half ropes, you can either use the twin rope technique in which the ropes are placed parallel through the piece of protection or the half rope technique in which the ropes run in two different protection points. The half rope technique minimizes friction and is beneficial when going up traditionally protected routes.
All three climbing rope types have distinct characteristics. Being familiar with their features as well as their specific uses leads one to be able to know what to use in a particular climbing situation.
