Movement on single rope The rope setup does not change between access and work: if the top anchor is reliable and verified, the arborist does not necessarily need to climb to the top and can go directly to the workstation.
The rope does not run during movement; the arborist can thus move anywhere in the tree with no loss of efficiency.
Movement on doubled rope The work rope is set up doubled through a friction saver, on a suitable anchor near the top of the tree.
This technique allows for easy travel in any direction and provides the arborist with good support when limb walking.
To learn more about access and movement techniques, see the technical information available at www.petzl.com
