The RIG may be used as a progress capture device to tension a rope.

It allows tensioning of the rope without damaging it in case of overloading, and releases easily.

The system is designed for light loads: one or two people depending on the application and the situation.

Warning: the installation presented here is only part of a system. A complete system must include (depending on the terrain) at least one supplementary rescue or backup rope.

Tensioning the tyrolean:

RIG handle in "belay" mode.

Simple haul: two people pulling.

Tensioning the tyrolean.

Using the tyrolean:

RIG handle in "work positioning" mode.

Mule knot in the free end of the rope at least 1 m from the RIG.

An occasional overload can cause the rope in the RIG to slip (up to 80 cm). This slippage helps dissipate the shock load and must not be hindered by the knot.

The knot limits rope slippage through the RIG in case of a prolonged overload.

Using the tyrolean.


Releasing the system:

Releasing the system.


To lower the user during a traverse, add a braking carabiner to the RIG's anchor point. Use the handle in "descent" mode while holding the brake side of the rope to control the rate of descent.

Dismantling the system:

If the tension is too high, using the handle can be difficult; reinstallation of the haul system may be required.

Loads on the anchors:

Manual hauling on a 10.5 mm rope can produce a tension of 3.5 kN before the system is loaded. An initial tension that is too high reduces sag, but increases strain on the anchors.

Rope slippage in the RIG also reduces the risk of overloading the anchors: see the tests for static slippage values.


A rope tyrolean will sag once it is loaded. Make sure there is enough clearance under the rope to allow the load to move without striking the ground, or an obstacle.

WARNING: never tension a rope with a winch or a car: an over-tensioned tyrolean can damage the RIG and generate significant forces on the anchors and on the rope. If you need high tension, use a cable with an appropriate tensioning system.
