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.
• Use spreader bars to avoid unit damage.
• Spreader bar must be a minimum of 11 feet for 20 to 85
ton units and 12 feet for 90 to 110 tons. Chains must
not bear on top of unit.
• Run straps through fork pockets to connect to the
spreader bar. See detail in Figure 6, p. 19 and Figure
8, p. 20.
• Lift using overhead crane only. Adjust rigging for unit
center of gravity.
• Unit center of gravity will fall within center of gravity
block at various locations depending on unit options.
• See unit nameplate for unit weights.
• Unit has built-in fork pockets for easy forklift
maneuverability.
• Do not stack units.
