ASWP06 Rigging Trees
4.2 Rigging Tree for Felling
Step Action
Determine appropriate attachment
point(s) in the tree being rigged
Note: All trees should have a pull
rope installed into the tree, if the
tree could fall in another direction
then the intended direction of fall.
Place rope(s) at least 2/3 the distance up the tree
(Figure 2) from the point intended for the cut
location
Consider when roping a tree:
o Multi-stemmed trees
o Split trees
o Diseases, tree defects, etc.
Note: Ropes must be of sufficient length to keep all
workers and equipment out of the Drop Zone during
felling operations.
Install Split Prevention system (if
required)
Ensure split prevention system is in place if
required
Note: Split prevention system must be able to
withstand the loads applied to the tree being removed.
Install a guide rope (if required)
Note: All trees shall have a guide
rope installed if they could fall in a
direction other than intended.
• Guide rope (Figure 2) should be placed at least
2/3 the distance up the tree from the point
intended for cutting
A guy rope:
Helps keep the tree directed in the intended
direction of fall
Prevents the tree from felling in an unintended
direction of fall (e.g. overhead utilities, building, etc.)
Install additional rigging equipment
to be used (if required) for a re-
direct or mechanical advantage
Install:
Slings
Blocks
Pulleys
Connecting Devices
Ensure rigging system and equipment are in
appropriate locations and ready to use
Determine method required to pull
tree over
Use of ground persons (Figure 2)
Mechanical pulling devices
Mechanized pulling devices
Begin procedure for cutting tree
Follow ASWP05 Tree Removal
Prior to cutting, operation must be stopped
and all personnel must receive and confirm
that everyone is ready for the "Back Cut"
