Tying-off the PIRANA
When rappelling, it is sometimes useful to stop the descent in order to perform various tasks (install a deviation, untangle the rope...). To do this, the descender is tied off to immobilize it.
- 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.
There are several kinds of tie-off, which is selected depending on the context (rappelling with feet supported, or free-hanging) and/or according to the maneuvers to be performed:
1. Temporary stop.
You must keep a hand on the brake side of the rope.
2. Long duration tie-off
Here are two tie-offs that allow both hands to be free, with maximum security.
The second tie-off is not recommended for free-hanging rappels because it can be difficult to undo, which is problematic on a waterfall rappel.
