A climbing rope, is composed of two basic parts; the soul and the shirt.
The shirt includes the outer part of this and the soul includes the inner braid.
When we suffer a fall the rope lengthens, absorbing the energy of the fall and transforming it into heat. The elasticity depends mostly on your shirt. The more elasticity the shirt has, the more energy it will absorb, but the shorter the life span it will have.
Elasticity is always measured with the same parameters; a weight of 80 kg is hung and how much has been stretched is measured. The maximum elasticity is limited to 8% in single climbing ropes and 10% in twin and double ropes.
Static should not be used for climbing and are not approved by the UIAA. Ideally, they can be used to climb a rope or for other activities such as canyoning.
TYPES OF CLIMBED ROPE ACCORDING TO ITS DIAMETER
SIMPLE FAT ROPES
The diameter goes between 10 and 11mm. The advantage they present is that they resist more uses, this is especially noticeable in hard rocks or with sharp edges. They go well to make top rope or for large walls. The biggest disadvantage they present is that they are very heavy and take up a lot. The UIAA establishes its number of falls from 10 to 17.
SIMPLE COMMON ROPES
Its diameter varies between 9.5 and 10mm. They are the most common because they are not excessively heavy or excessively light. They are used both in sport climbing and in long way. The UIAA establishes its number of falls from 7 to 9.
STRAIGHT THICK ROPES
Its diameter varies between 8.9 and 9.4mm. Your weight is considerably low which can be favorable on alpine routes or if you need to charge for a long time with it. Their main disadvantage is that they need a special insuring device for thinner diameters. The UIAA establishes its number of falls from 5 to 6.
Its diameter varies between 8 and 9mm. Whether on ice or rock, these are always useful on long climbs where you probably have to rappel. In addition, they are very useful because they allow us to share the weight with our rope partner. The UIAA establishes its number of falls from 6 to 16.
Its diameter varies between 7 and 8mm. They are lighter and less bulky than the doubles and you can join them in the same way to rappel. The only difference is that they always have to be plated together, as if it were a single rope. The UIAA establishes its number of falls from 12 to 19.
TREATMENTS ON CLIMBING ROPES
This treatment helps the climbing ropes are not damaged so easily when rubbing with sharp edges. It is recommended in long way and in classic climbing, but it is also good for sport climbing. Thanks to this treatment is less likely to be damaged and, consequently, lasts longer.
When the rope gets wet, it loses energy absorption capacity. If the temperature is low enough, the water can freeze inside the jacket and damage the wires inside. The dry treatment helps to absorb less water when it gets wet (although it always absorbs some water). In ice climbing, this treatment is essential.
It is the force that a climber receives during a fall. It is measured by subtracting the energy produced by the fall and the energy absorbed by the string.
NUMBER OF FALLS
This number does not have to alarm the consumer. It does not mean that if you fall more than the indicated number the string will break.
All the climbing ropes are tested in a laboratory with a weight of 80 kg and with a fall factor of 1.8. It is considered that the number of falls has been reached when we exceed 1200 kg of impact force. That is to say that it would not break when exceeding this number of falls established, but it would no longer be as efficient.
It is the process by which the shirt and soul of the climbing rope is joined. In this way, if the shirt is scratched or frayed a little, the soul will not run inside.
A great advance in security has been made thanks to this treatment.
HOW TO TAKE CARE OF YOUR CLIMBING ROPE
It is important to keep it clean. It is common to get dirty with sand or pebbles that are especially abrasive. To wash it, you can use a special soap (easily replaceable by neutral soap). Aclárala conscientiously and tend it in the shade. Never wash it in the washing machine and never let it dry in the sun.
It must be inspected after each use, to confirm that the shirt has not been damaged. In case this happened you can cut the affected part, leaving two ropes or (if the affected part is near one end) pulling the affected piece.
Keep in mind that if you are climbing on hard rock or on a path where it rubs excessively, it would be ideal to have a rope with a thick diameter.
Finally, falling is very aggressive for the rope; Do not forget to tie yourself each time for a different end, to share this tension that is occurring.
WHEN TO REMOVE YOUR CLIMBING ROPE
Even without giving much use, the passage of time causes the loss of its properties. After 4 years, it is highly recommended that it be replaced by a new one. If the use is once a week, it is recommended to change after two years.
If you have suffered a hard fall recently or if you have any other doubt, it is preferable to change it and buy a new one.
