EJECT and NAJA can be used on a single rope
(SRT/SRS) with a stopper knot.
Moving within the tree with two anchors
Using two systems simultaneously on two separate
anchors provides optimal balance while cutting and
facilitates movement.
Movement Within the Tree
EJECT and NAJA are used here
on doubled rope (DdRT/MRS),
but may also be used on single rope
(SRT/SRS) with a stopper knot.
Single rope
ascent technique
The access rope is attached
to the base of the tree and runs
through an appropriate anchor
in the tree. It will also be used
for work. On a single rope,
the ZIGZAG must only be
used with the CHICANE.
This technique allows for rapid
rescue and efficient climbing
with the KNEE ASCENT knee
ascender.
Tree Access
Doubled rope
ascent technique
The arborist ascends
the access rope (purple).
In the event of a problem,
such as a hornet attack,
they can self-evacuate with
the work rope (blue). A mule
knot or releasable knot secures
the ZIGZAG.
This versatile ascent technique
is adaptable to many situations
and allows an access rope
to be available during work.
