Dismantling: second belay point and evacuation system on the ZIGZAG in single mode with CHICANE
The ZIGZAG rope can be choked around the trunk, or be choked with a friction hitch. So the ZIGZAG is in single mode and must be used with the CHICANE auxiliary brake.
- 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.
Note: in this document the name ZIGZAG means either the ZIGZAG or ZIGZAG PLUS models.
During cutting operations, the arborist must use two belay systems.
The positioning lanyard is the first system.
The ZIGZAG, installed on a choked anchor, serves as the belay system as well as the evacuation system.
The ZIGZAG is not designed for working in single mode without an auxiliary brake.
To recover your equipment, connect the other end of the rope to the "choke" carabiner.
