  • Climbing Ropes

    The ropes used in climbing are dynamic type, their elasticity absorbs shock and reduces impact forces on the anchor points. The soul is either braided rope or cable. A rope with a braided core reduces the effect of slippage between the core and cladding.

    There are three distinct types of rope, single ropes, double ropes and twin ropes.

    Single ropes

    They are generally used on long routes. They are also used on multi-pitch routes that do not require a rappel descent. Be careful , this choice can cause problems if survives (read the topo).

    The strings have a single mark - 1 - on white ribbons located at the end of rope.

    The diameters used are between 9.8 and 11 mm and a weight of about 70 grams per meter. The lengths vary between 50 and 80 meters and the choice depends on the use.

    To know that the manufacturers materialize the middle of some single ropes with a black marker, very useful when using the rope for a reminder. There are even single ropes bicolor, another method for identifying the middle.

    The double ropes

    Also called string of rappel, they are used in high mountain and cliff paths. On this type of rope is not clipped generally a bit during the ascent especially if the belay points are random and require very low impact force during a fall, so the ice fall ice for example.

    The strings have a double marker - 1/2 - on the white ribbons located at the end of rope.

    The diameters used are between 8.1 and 8.6 mm for a weight of about 45 grams per meter. The lengths vary between 60 and 100 meters. Usually choosing a reminder door to 90 or 100 meters. If you are unsure, choose 100 meters, you will everywhere.

    Twin ropes

    This type of rope is lighter than the double ropes, used only in high mountain routes. Just like the double ropes are used in two strands, but always carabiner attaches both during the ascent.

    Twin ropes are a landmark - OO - on white ribbons located at the end of rope.

    Note that this type of rope is less manufactured.

    Specific treatment

    The strings can undergo treatment for the waterproofing, the "dry treatment". They are essential for climbing ice climbing. Disadvantage, they cost more but seem more resistant to abrasion.

    Maintenance and storage

    If your rope is dirty, you can wash it with clean and cold water and bosser with a synthetic brush. Drying takes place away from any heat source.

    The strings must be stored away from light, UV, moisture and dust.

    Life

    Life depends on the frequency and mode of use. The rope may suffer irreparable damage from its first use. Generally, this life is between three and five years. But in case of intensive use this time can be much smaller, on the order of a few months!

    Storage time and cumulative use shall not exceed ten years and know that in use a rope grows and can lose up to 5% of its length.

    The vintage

    To know year of manufacture of a rope, simply identify the color of the central core of the rope (the section), watch the color depends on the manufacturer.

    Some tips

    When you buy a rope, read the leaflet that accompanies it. The impact force is indicated either books or in daN (deca Newton). Remember that the higher the number, the greater the impact is significant on the anchor points and the body of the climber in case of a fall. A equivalent diameter, take the rope that has the smallest number. Static elongation is closely related to the impact force. An important extension means good elasticity of the rope. It is better to rely on the force of impact and static rather than the number of falls elongation.

    Always take good care of your rope, do not walk on and leave it lying at the foot tracks in the dust. It is better to put it in a rope bag, it will protect you and also avoid having knots and twisting problems, which is always very unpleasant.

    After each use, inspect the rope along its entire length to ensure that the sheath did not suffer damage.

    Avoid descents lowering or too fast reminder that accelerate sheath wear.

    In conclusion

    Rope climbing is an essential element in the safety of the climber chain. This is a personal item, you should take the most care and to know your experience. It is also necessary to know how to separate when the time came.

    Static ropes

    They are used in caving, for rescue, but also for long rappel. Elasticity is much lower. They reduce the effect of "yoyo" in big descent. However, they absorb very little kinetic especially for small lengths of rope energy. Their elasticity coefficient varies by manufacturer. Using static strings can be very dangerous , the shock strength quickly becomes critical even for a very small amount of fall.

    Good write up Dom! I used to do arborist work, somewhat down the same line.
