ITCC Climbers' Workshop
These
2015 MASTERS' CHALLENGE CHAMPIONS will demonstrate and discuss double-rope technique (
DdRT), single-rope technique (SRT), and redirect techniques to improve
efficiency, work-positioning, and safety.
Redirect Workshop Outline
1.
Introduction
a.
Redirects allow climbers to fine-tune their
position in the tree by providing an improved working angle without having to
change their main tie-in-point.
Redirects also reduce the chance of an uncontrolled swing as a climber
performs a limb walk or works further away from the original tie-in-point. If you climb DdRT or SRT, there are two major
techniques for redirecting the climbing line: mechanical (false) redirect and
natural redirect. (Tree climbers companion- Jeff Jepson)
b.
ANSI Z133
i. 8.1.24
: A false crotch and/or false crotch redirect may be used at the discretion of
the arborist in lieu of a natural crotch.
ii. 8.1.25:
The tie-in position should be well above the work area so that the arborist
will not be subjected to an uncontrolled pendulum swing in the event of a slip.
c.
Dynamic vs. static redirects
i. Briefly
go over angles of deflection and how redirects can increase or decrease
load. In some cases dynamic redirects
can cause the branch to be loaded in a fashion that is unnatural, pulling the
redirected branch towards the main tie in point.
