Tree care
    18


           Not all tree work can be done
           using exterior means such as
           elevated platforms or ladders.
           In this case, to move and
           work, the arborist uses rope
           progression techniques.

           Examples of operations:
           • ornamental tree trimming,
           to adapt the tree to its
           environment or to change
           its overall aesthetic
           • maintenance trimming to
           remove dead wood and dying
           branches
           • tree removal (progressive
           cutting of the trunk from the
           top) if diseased or presenting a
           hazard...

           Technical specifics:
           • access from the base of
           the tree generally starts by
           throwing a weighted bag with
           line attached. This line is used
           to install the access rope on an
           anchor up in the tree
           • while moving about on the
           branches, the arborist keeps
           his/her weight on the work
           rope, for greater stability and to
           reduce the potential fall distance
           • when using any cutting
           tool (hand saw, chainsaw),
           the arborist must use two
           independent belay systems

                                                                  The ROLLCLIP Z pulley-carabiner (TRIACT-LOCK version)
                                                                  has the gate opening on the non-pulley end, to facilitate
                                                                  installation on devices. It can be used to attach the ZIGZAG to
                                                                  the attachment bridge on the SEQUOIA harness, for improved
                                                                  lateral mobility.
