Prusik knot

Nudo PrusikThis knot was discovered by Dr. Karl Prusik in 1931. The Prusik knot is used by climbers and climbers to hold the rope slings to slide freely so that when the knot is loose, but stands firm with any lateral load.

It is used as a safety device in the declines in "rappel" (down a vertical wall using a double rope attached to a high point). The "prusik" ​​is useful for anyone who wants to scale heights complicated-for example, studying botanical trees, or climbers and cavers.

The "prusik" ​​knot always slides easily, and once the load is in place, holding the load may loosen and release the turns of rope. The knot should be done with a rope much thinner than that on which it is, and it is important to remember that the rope may slip if wet or icy.

This grip knot is symmetrical so it is very useful for loads that have to be applied in any direction. For loads are always applied in the same direction is preferable to use other knots, how Klemheist or Bachmann.

Uses: Its main use is to climb a rope. It uses two Prusik knots alternately to slide down a rope static long Prusik loop allows the climber to climb through the strength of his leg and a shorter second loop Prusik is tied into the harness. In rescue, if a climber has to be uploaded, you can use a Prusik loop to attach a locking system to the climbing rope.
