12 TREE CARE For moving and working in trees, when it is not possible or appropriate to use an exterior means (elevating platform, ladder...), the arborist uses a rope progression technique. To do this, he sets up a rope from the ground and installs an ascending system which is determined by the configuration and height of the tree. Once the arborist is in position, he should be comfortably and correctly positioned (harness with attachment bridge and adjustable lanyards). The work positioning system should always be backed up during a cutting operation. NEW 2015 SEQUOIA and adjustable attachment bridge The SEQUOIA is a tree care seat harness for ascents on a doubled rope. It is designed for the arborist's comfort. The extra-wide, semi-rigid waistbelt and leg loops give excellent support. The adjustable attachment bridge allows quick and precise adjustment of the position of progression tools installed on the bridge.
