1. Confirm unit does not need additional moves by fork lift.
2. Prepare unit for rigging as follows:
• 6 to 12.5 ton units: Remove all drill screws
fastening wood protection to metal base rail.
Remove all screws securing wooden protection to
wooden top crate.
• 15 to 25 ton units: Remove the front base rail
bumper protection.
Note: For unit protection, the top crate should remain in
place during lifting. If it must be removed prior to
lifting, protect unit from damage. Top crate must
be removed prior to operation.
WARNING
Improper Unit Lift!
Failure to properly lift unit in a LEVEL position could
result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only
damage.
Test lift unit approximately 24 inches (61 cm) to verify
proper center of gravity lift point. To avoid dropping of
unit, reposition lifting point if unit is not level.
3. Rig the unit as shown in the weights section. Attach
adequate strength lifting slings to all four lifting brackets
in the unit base rail. Do not use cables, chains, or slings
except as shown.
4. Install a lifting bar, as shown in the Dimensions and
Weights chapter, to protect the unit and to facilitate a
uniform lift. The minimum distance between the lifting
hook and the top of the unit should be 7 feet.
5. Test-lift the unit to ensure it is properly rigged and
balanced, make any necessary rigging adjustments.
