4.3 Rigging Sections of Trees Aloft
In some situations a tree will have to be rigged and sections of the tree cut and lowered to the
ground because the tree cannot be removed in one piece. The following work practice outlines
the process to sectionalize a tree for removal.
4.3.1 Establish Rigging Points
Step Action
Choose limbs or branch unions to
run lines over/through or attach
rigging blocks
Points for rigging must be in suitable locations
that are of sufficient size and strength to carry
loads applied
Rigging locations must be wide enough to
allow free movement of rigging lines
Identify the path of travel for lowering limbs or
sections of tree
Install lines, slings and or rigging
blocks (Figure 3)
Ensure rope size, strength; material and construction
are appropriate for rigging line application
Ensure that anchor points are of sufficient size and
strength, incorporating an applicable safety factor
Ensure ropes are compatible with other rigging
devices such as friction devices, blocks or pulleys
Ensure rigging lines are attached using suitable
knots and are at appropriate locations on the limb to
be removed
