Mountain climbing rope strength is one of the critical variables in any climb, but how can you choose which strength you will need? Ropes are an essential part of mountain climbing equipment, and can be used in a variety of ways. For climbing purposes rope strength refers to two different factors, the maximum impact force and the static elongation. The maximum force impact of mountain climbing rope rates the amount of force from the fall that will be transmitted to you, the climber. The static elongation of the rope refers to how much stretch the rope provides when a standard weight is used.
Mountain climbing training is important, but even the best training can not help if you find yourself in a tough position with the wrong rope strength and abilities. If you choose a maximum impact force rating which is low then any force from a fall will be cushioned better but the increased stretch of the rope will allow you to fall longer, which could result in landing on ledges or the ground. The right mountain climbing rope will depend on where you will be climbing, as well as other factors like the type of rocks being climbed. Even your type of climbing webbing can affect which rope strength is best.
Each mountain may have different ideal mountain climbing rope strength and climbing techniques, but if you do not have the money to buy fifteen or twenty types of ropes you can choose a general all purpose type which works well in most conditions. Consider the heights that you will be ascending to, and the distance of any possible falls before a rock ledge or the ground can become a hazard. You will want to choose a rope which offers the best possible maximum impact force and static elongation so that there is no risk of hitting bottom but that you are also not injured by the force of the fall at the same time. Proper rope car is also important, and just like your climbing shoes your ropes should be inspected before any use.
