ISA Arborist's Certification Exam
Chapter 16 Climbing and Working in
Trees Solved Correctly To Score A+!!!
3 strand CORRECT ANSWERS Three strands twisted together in a spiral pattern
12 strand CORRECT ANSWERS For arborists rope- a braided rope consisting of
strands, most are coreless; a tight braid that is not easily spliced. - used for rigging and
climbing, and a loose easily spliceable braid, commonly used for slings
7 Strand CORRECT ANSWERS Common grade, steel cable construction, Used to add
supplemental structural support to trees. Terminated by wrapping onto itself
16 strand CORRECT ANSWERS For arborists rope-, load bearing cover and a filler
core that is not significant in load carrying
24 strand CORRECT ANSWERS For arborist ropes, available in double-braid or
kernmantle construction
access line CORRECT ANSWERS Second climbing line in a tree in case it is needed to
reach a victim in an emergency.
and or a climbing line installed in a tree to gain access to, but not used to work in the
tree
arborist block CORRECT ANSWERS Heavy duty pulley with an integrated connection
point, a rotating sheave for the rope and extended cheek plates. Used in tree rigging
operations
ascender CORRECT ANSWERS Piece of gear that enables a climber to ascend a rope.
attached to the rope, it will grip in one direction(down) and slide in the other (up)
back cut CORRECT ANSWERS Cut made on a trunk or branch, opposite from and
toward the notch, face cut, or undercut, to compete felling or branch removal
balance CORRECT ANSWERS in rigging, a technique for lowering a limb without
allowing end to drop
bend CORRECT ANSWERS Type of a knot used to join two rope ends together
bend ratio CORRECT ANSWERS Ratio of the diameter of a branch, sheave, or other
object to the diameter of the rope that is wrapped around
, bight CORRECT ANSWERS Curve or arc in a rope between the working end and the
standing part
blake's hitch CORRECT ANSWERS Friction knot climbers use, sometimes in place of
the tautline hitch or prusik knot
block CORRECT ANSWERS 1.Heavy duty pulley used in rigging, designed for dynamic
loading. 2. casing enclosing one or more parallel pulleys
body thrust CORRECT ANSWERS method of ascending a tree using a climbing rope
bollard CORRECT ANSWERS post to tie off with to provide friction
butt-hitching CORRECT ANSWERS Lowering pieces when the rigging point is below
the work, traditionally without the use of a block
butt-tying CORRECT ANSWERS tying off a limb at the butt (larger) end of rigging
carabiner CORRECT ANSWERS Connecting device. Oblong metal ring used in
climbing and static rigging that is open and close spring loaded gate.
climbing hitch CORRECT ANSWERS Used to secure a tree climber to the climbing line,
which permits controlled ascent, descent, and work positioning
climbing line CORRECT ANSWERS rope that meets specs for use in tree climbing
climbing saddle CORRECT ANSWERS work positioning harness designed for climbing
trees
clove hitch CORRECT ANSWERS Knot used to secure a rope to an object
cycles to failure CORRECT ANSWERS Number of times a rope or other piece of equip .
can be used with a given load before mechanical failure
design factor CORRECT ANSWERS factor by which the rated or minim. breaking
strength of a rope or piece of equipment is divided by in determining its working load
limit.
drop cut CORRECT ANSWERS branch removing technique consisting of an undercut
and then a top cut, usually made a farther out on the branch, or with a chainsaw,
directly over the undercut
dynamic loading CORRECT ANSWERS Forces created by a moving load. Load that
changes with time and motion
figure 8 knot CORRECT ANSWERS Safety knot or stopper at the end of a line
