Tensioning a tyrolean with the GRIGRI or the NEOX
Warnings
- Carefully read the Instructions for Use used in this technical advice before consulting the advice itself. You must have already read and understood the information in the Instructions for Use to be able to understand this supplementary information.
- Mastering these techniques requires specific training. Work with a professional to confirm your ability to perform these techniques safely and independently before attempting them unsupervised.
- We provide examples of techniques related to your activity. There may be others that we do not describe here.
Fix one end of the rope to an anchor point. Install the other end of the rope in the GRIGRI or NEOX, making sure to put it into the device in the right direction. Connect the device to a second anchor point with a locking carabiner. Lock the carabiner.
Tension the rope by removing all slack. The tyrolean must be hand-tensioned by one person, using a 3:1 pulley system if necessary, or hand-tensioned by two people.
Once the rope is taut between the two anchors, secure the GRIGRI or NEOX by making a tie-off against the device.
WARNING: a tyrolean creates a very high load on the anchor points.
Make sure the anchor points are sufficiently strong.
Falls are prohibited on tyroleans.
WARNING: unblocking an over-tensioned or overloaded tyrolean can be difficult. GRIGRI and NEOX are not covered under warranty if you break the handle because your tyrolean is too tight.
Tip for unblocking: make a 3:1 haul system as indicated in the diagram. Pull on the free end of the rope to release the tension in the device and make the handle easier to use.
