There are an infinite number of strings for sports like rock climbing, mountaineering, canyoning. Today I will try to give some light to those who know very well what kind of rope should be purchased for your sport.
Shirt: The outward and visible part of the rope. Its main function is to protect the soul from dust, UV and abrasion, also provides, depending on the type of rope, between 15 and 35% of total resistance thereof.
Static ropes: They are composed of inelastic and manufacturing polyamides, the fibers are arranged in parallel to avoid the "yo-yo". They are used for lifting or moving loads and to climb them with blockers.
String dynamics: This type of rope can absorb the energy generated by the impact of a fall due to its ability to stretch. The large capacity of the achieved elongation manufacturers using elastic and polyamide braided spiral (I spring effect) yarns and threads of the soul. Intended for all those activities where there is a risk of falling from a point that is above the place of insurance. However, the ascent of these blockers is uncomfortable due to the effect samuel j of shrinkage-producing stretch. Furthermore, shirts spoil quickly with blockers.
The strings are usually made with different diameters, but each range has its use. The diameters of less than 8 mm are called slings and are used only for use as auxiliary ropes or rings. Double or twin ropes typically have diameters between 7.8 and 9.8 millimeters. While simple strings Estane between 9.9 and 11.2 mm, being more usual 10.2 and 10.5.
The Randone strings are just strings to be strung (attached to each other) in trekings or climbs, both glaciers and climbs, do not climb with them, typically measure 30 or 48 meters.
The elongation or stretching ability of a rope (and therefore to absorb the energy produced in a crash) is the ability to stretch the ropes and to extend its size when subjected to a crash.
The fall factor is the ratio obtained by dividing the number of meters of fall between the number of meters of active rope between the climber and the belay point, ie f = (height of free fall) / (active length of a string). The biggest factor that can result samuel j in a fall factor samuel j is 2, this is when the climber falls twice the length of the current string.
The higher the number on the label of the string, the greater the safety and reliability over time. There are three key factors that make a more or less durable samuel j rope: First, the abrasion resistance of the shirt. The second elongation is, as a rule, the greater the capacity of elongation of a rope, the lower its durability. And a third factor is the accumulation of small impacts suffering, they are slowly subtracting elongation capacity of the cord.
No stretch for pleasure samuel j (when scaled, and the former does not reach a point on the wall, their friends often help pulling the rope to raise, this strongly samuel j discouraged)
Then, pull the rope and pull the water refilling water and neutral soap put, the dentro.Despues hechar remober and passing the rope rope cloth or soft cloth or a special brush to clean ropes.
Once past the string about twice a brush, cloth or rag, will be clean, we only dry. To do this we hang the rope on a stick or similar and let it dry for about 6 days in a shaded place, you can not take the sun and neither should touch the string loops together.
