Advanced equipment techniques

TGV assembly:

The "TGV" assembly is a technique for equipping large verticals and / or verticals of the "adventure field" type.

A person descends on two blocked strands: Indeed, in large verticals or in "adventure playground" the risks of rope breakage are greater due to:

- The presence of possible friction: accentuated by the height.

- And / or risk of falling rocks.

This equipment technique makes it possible to individualize each strand of rope (safety in the event of a strand breaking and possibility of climbing up on a single strand). It also allows the friction points to be moved between each crew pass. Finally, the weight of the person descending is distributed over the two strands, reducing the "yoyo" effect which can damage the rope by friction.

The most of the "TGV" technique: Keep a disengageable option.

Note: It goes without saying that the declutching option can only be implemented if the group has a third length of rope as provided in the safety rules.

Double disengageable:

The Double Clutch allows the installation of a disengageable assembly on two strands (that is to say that two people can descend simultaneously on each one strand of rope).

Unlike the "Alternative Joker", this assembly allows you to free one or the other person (or both) at any time, which makes it usable when going down water.

This assembly allows an adjustment of the two strands "above the water", also it is suitable for an arrival in basin and / or with water movements.

This technique makes it possible to significantly optimize the group's progression time.

The implementation of the declutchable double remains reserved for experienced people.

Note: This assembly can of course allow the descent of 1 person on double rope

With strands blocked:

A simple and original solution ... On classic ammarage or on AN (Ammarage Naturel)

Relay shifted:

The implementation of an offset relay is suitable for waterfalls with a "broken". This technique allows the positioning of the leader at the break in order to:

- bring team members to hand on handrail

- remove the friction point due to breakage

- visually check the descent of team members

- keep disengageable equipment.

Disengageable "in stop":

ATTENTION: this technique is still taught as a basic technique by some schools !!!

This technique is responsible for too many) accidents.

The "Joker" type equipment being so simple, but much safer, we have relayed the "stops" in the rank of advanced techniques, to be used only in specific cases and requiring absolute vigilance.
