- Specific machine knowledge and training how
to properly rig the load.
- Full responsibility for all aspects of the lift.
Interrupt the lift if not fully confident of a safe lift.
Select machine with sufficient capacity for the
total expected load, reach and swing. Ideally, load
should be less than the load listed on the load
chart at maximum reach across the
undercarriage.
- Know the mass (weight) of the item to be lifted.
- Know the start and finish positions, load lifting
position and setting position.
- Know the machine configuration, especially the
dipper arm and boom lengths and track size.
- Choose the correct lifting chart taking into
account all attachments and rigging materials
that will be used during the lift. The weight of
the rigging materials and attachments, should
be deducted from the load capacity.
Warm up the machine to normal working
temperatures.
Position the machine on firm level ground.
Properly set outriggers and blade when
applicable.
Once the load is properly rigged, ensure all
ground workers are clear of the load and the
machine. If guiding of the load is necessary, use
ropes or other type of slings tied to the load to
keep ground workers at a safe distance.
Use a trained signalman to direct all aspects of
the move.
Do not use the swing or arm-in operation to drag
a load.
