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 must stay balanced and comfortable (harness with attachment bridge and adjustable lanyards). The work positioning system should always be backed up during a cutting operation. A ALVEO VENT / VIZIR: lightweight and ventilated helmet for work at height with system for mounting hearing protection and a face shield. B SEQUOIA SRT: arborist seat harness with ventral attachment point, allowing great mobility and comfort. C ASCENTREE: double-handled ergonomic rope clamp for tree access.
