Unit Lifting Points
Preferred Lifting Method
The preferred method for lifting an AFDH drive unit to
position it for installation, is to use an identical individual
hoisting device at each lift point.
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only damage.
Ensure that all the lifting equipment used is properly
rated for the weight of the unit being lifted. Each of the
cables (chains or slings), hooks, and shackles used to
lift the unit must be capable of supporting the entire
weight of the unit. Lifting cables (chains or slings) may
not be of the same length. Adjust as necessary for even
unit lift.
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. An AFDH
cabinet assembly is top heavy. 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.
Do not lift such that any angle is placed on the lifting
tabs. They must only be lifted vertically.
