Arborist techniques allow a tree to be trimmed or completely removed log by log. Dependin on the case, movement and progression take place either around the outside of the tree or on the inside.
To move around freely and efficiently, arborists put up a rope from the ground and then install a device for ascending the rope, chosen based on the shape and heigth of the tree. Once the arborist is in position, he needs to remain balanced and comfortable (adjustable lanyards). The work positioning system should always be backed up while cutting.
