Tree care
When it is not possible or appropriate to use an exterior means (elevating platform, ladder, etc.), 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 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.
D PANTIN: right- or left-foot-mounted rope clamp for increasing efficiency during rope ascents.
E MOBILE: ultra-compact pulley with swinging side plates, ideal for pushing a friction hitch.
F TREESBEE: false crotch with color-coded ends for easier recovery from the ground.
G ECLIPSE: practical storage for throw-cords and bags.

Tree care
Installing a double rope.
The arborist creates his working rappel. He can use this rope to self-evacuate, for example in the case of a hornet attack. A mule knot, or a releasable knot, secures the Prusik.

• Single rope access technique• Double-rope access technique
Installing the rope: system is releasable from the ground in case of a problem during the ascent (e.g. attack by hornets…). Quick and easy installation.
The traditional technique is physically demanding, requiring great skill in locking the rope between the feet.
Ascending on a double rope is more efficient and less demanding.
Efficient technique for long ascents, requiring the SEQUOIA SRT ventral attachment point.Inf
