- Performing 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. Other techniques not described here may also exist.
While moving around in the tree, the free rope must have been managed so that it stays hanging in the area to which the arborist wants to return.
The excellent efficiency of the ZIGZAG allows work in the second area, even if the path of the free rope is complex.
The arborist must disconnect himself from his ZIGZAG to effect the deviation. He must take precautions to avoid "losing" it high in the tree as the ZIGZAG tends to slide on the rope, pulled by the weight of the free end.
- Always tie the ZIGZAG off on the rope, before disconnecting from it.
- Always reconnect to the ZIGZAG before undoing the tie-off.
