                   SAMSON:
                   Working with arborists on solutions
                   to real-world problems.
                   climbing lines have come a long way from the
                   three-strand manila that was prevalent in the early
                   seventies. it was during that time that samson was
                   asked to develop a new synthetic line to replace
                   the manila climbing lines in use by arborists. We
                   consulted with professional arborists, universities,
                   and distributors. After fourteen months and seven
                   design evaluations, Arbor-Plex emerged as the first
                   synthetic braided rope designed specifically as a
                   climbing line for the arborist. With industry acceptance
                   of Arbor-Plex, samson saw the demand for a higher
                   strength, lower stretch climbing line that would allow
                   good visual recognition. True-blue was developed
                   in response to that demand. Tree-master followed for
                   those traditionalists who preferred a three strand, but    tHe saMson aDVantage

                   wanted the increased strength and lower stretch of         Samson is committed to meeting the

     AND POLYOLEfIN fIBERS
      The unique construction of Arbor-Plex wraps tough polyester jacket fibers around polyolefin
      center fibers creating a lightweight, high-strength rope with maximum resistance to wear
      and fiber fusing. Arbor-Plex uses a proprietary construction to tighten the braid and keep the
      rope round and firm for knot control and snag resistance. The outer polyester fibers utilize
      Samson’s Parallay fiber orientation to prolong rope life by minimizing the sawing action of
      fibers over rough surfaces. The signature green stripe assures that any twist in the line is
      easily detectable.
      Arbor-Plex was the first synthetic rope designed specifically for the arborist industry and
      remains one of the best values in climbing lines today.

     Two commonly used climbing systems are the traditional and the modern split-tail system. The differences
     between these two systems are illustrated below.




                                                           TRADITIONAL SYSTEM
                                                           The traditional climbing system
                                                           utilizes a climbing line dead-ended
                                                           to the saddle with a bowline leaving
                                                           a long tail. The tail is then attached
                                                           to the other part of the climbing line
                                                           by tying a climbing hitch. This
                                                           system is limited to a one eye tail
                                                           and the tail is the same rope as
                                                           the climbing line.

                                                           Advances in technology have led to
                                                           new techniques that offer additional
                                                           benefits to the traditional system.

            Rigging

                 Rigging for tree removal is more complicated
                 than climbing and demands more experience                        Running Bowline
                 as well as an understanding of the effects on
                 the rope of the various knots and hitches used.
                 It is widely known that knots can significantly
                 reduce rope strength with a corresponding
                 reduction in the work load limit recommended
                 by a manufacturer. The rigging techniques
                                                                                        Half Hitch
                 and knots presented here are meant to give
                 a general overview of the basic principles of
                 rigging. Prior to beginning any tree work, it is
                 important to thoroughly examine the tree for
                 structural imperfection, faults or weaknesses
                 that could compromise safety. This text is not
                 a substitute for proper training.
                 One of the most potentially dangerous aspects
                 of rigging is “chunking out” large trunk
                 sections of wood that are rigged vertically                          Loopie Sling
                 upon themselves.
                 Safety, as always, is the primary concern. It
                 is important when rigging to minimize shock-                       Rigging Block
                 loads and manage friction efficiently. This is
                 easiest to achieve when using arborist grade
                                                                                    Lowering Line
                 rigging blocks in conjunction with appropriate
                 friction/lowering devices both of which have
                 been tested and rated.
                 Excessive shock loading must always be
                 considered when rigging. The rigging system
                 should be constructed to withstand the
                 maximum shock-load potential. Generally,
                 maximum shock loads are experienced in a
                 rigging system when the rigged piece is
                 “snubbed off” and not gradually decelerated.
                 Testing and research has shown that the block
                 and sling experience more than double the
                 shock load force than any other part of the
                 rigging system if the piece is “snubbed off,”
                 a situation to be avoided whenever possible.

            and provides stability and holding power.

              adjustable slings
            Loopies or Whoopie Slings are an excellent alternative to the
            traditional Timber Hitch as they can not come untied. The Timber
            Hitch can be used to attach a rigging block or a friction device to
            a tree as a lowering devise to lower or hoist limbs. This tendency
            for the hitch to come untied can be minimized by tucking for a
            minimum of 5 wraps, spreading out the tucks over as much of the
            circumference of the trunk as possible, and ensuring that the hitch
            is loaded “against the bight” whenever possible.

        Adjustable, load rated two eye lifting slings. The sling has a permanent eye splice
        at one end, and an adjustable eye at the other end that allows it to adapt to loads
        of various sizes. The adjustment allows snug lifting control and minimizes the
        number of fixed length slings required. With three sizes to choose from, there is
        a Samson Whoopie Sling for any lifting job. Each is permanently tagged with its
        capacity, polybagged and shipped in a carton.

3 RetiRement: RetiRe Rope fRom use when it has Reached its discaRd point
One of the most frequently asked questions is “When should I retire my rope?” The most obvious answer is before it breaks. But,
without a thorough understanding of how to inspect it and without knowing the load history, you are left making an educated guess.
Unfortunately, there are no definitive rules nor industry guidelines to establish when a rope should be retired because there are so many
variables that affect rope strength. Factors like load history, bending radius, abrasion, chemical exposure or some combination of those
factors, make retirement decisions difficult. Inspecting your rope should be a continuous process of observation before, during and after
each use. In synthetic fiber ropes the amount of strength loss due to abrasion and/or flexing is directly related to the amount of broken
fiber in the rope’s cross section. After each use, look and feel along every inch of the rope length inspecting for damage as listed below.

abRasion
When the rope is first put into service, the outer filaments of the rope will quickly fuzz up. This is the result of these filaments breaking
and this roughened surface actually forms a protective cushion and shield for the fibers underneath. This condition should stabilize,
not progress. If the surface roughness increases, excessive abrasion is taking place and strength is being lost. As a general rule for
braided ropes, when there is 25% or more wear from abrasion the rope should be retired from service. In other words, if 25% or more
of the fiber is broken or worn away the rope should be removed from service. With three-strand ropes, 10% or more wear is accepted
as the retirement point.
Look closely at both the inner and outer fibers. When either is worn the rope is obviously weakened. Open the strands and look for
powdered fiber, which is one sign of internal wear. Estimate the internal wear to estimate total fiber abrasion. If total fiber loss is 20%,
then it is safe to assume that the rope has lost 20% of its strength as a result of abrasion.

Synthetic fiber ropes are normally shipped on reels for maximum protection while in transit. The rope should
be removed from the reel by pulling it off the top while the reel is free to rotate. This can be accomplished by
passing a pipe through the center of the reel and jacking it up until the reel is free from the ground. Rope should
never be taken from a reel lying on its side. If the rope is supplied on a coil, it should always be uncoiled from
the inside so that the first turn comes off the bottom in a counter-clockwise direction.

                      The best method for making up braided rope is in
