Doubled rope progression device
The ZIGZAG is essentially designed for movement within the tree during the work phase: movement on branches, ascents and descents.
Single rope progression device
The ZIGZAG may be used on single rope only when combined with the CHICANE auxiliary brake.
Securing oneself at the workstation
When cutting, the ZIGZAG can be used to secure and stabilize the arborist, without changing the setup that is used for movement within the tree. A second independent system must be used.
Emergency evacuation system
Installed on a rope of sufficient length, the ZIGZAG can function as an emergency evacuation system, e.g. during access phases or when dismantling on the trunk.
