Relais d’alpinisme

As seen in Rope techniques walking corde tendue we use the environment (I.e rocks) has a security when progressing.

If it is safe it is unnecessary to vacher yourself. However if needed, most of the time it is enough to turn the rope around a rock two times; friction will do the rest.

To make a Relais, take a long sling and make a Noeud coulant on it. Pass the knot around the rock and tighten it.

Add a carabiner to the sling, put a Demi-cabestan on it and you can now belay people under.

Otherwise, one can do a Relais sans équipement.
