Recommended Rigging and
Lifting Procedures for AFDR Drive
Units
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 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 AFDR cabinet assembly is
top heavy. Test lift unit approximately 24 inches to
verify proper center of gravity lift point. To avoid
dropping of unit, reposition lifting point if unit is not
level.
Unit Lifting Points—Preferred Lifting
Method
•
The preferred method for lifting an AFDR drive unit to
position it for installation is to use an identical
individual hoisting device at each lift point.

individual hoists
Unit Lifting Points—Alternative Lifting
Method
•
If it is only possible to use a single hoisting device to lift
an AFDR drive unit to position it for installation, a
spreader bar should be used to allow adjusting the
rigging as necessary to balance the unit around its
center-of-gravity to ensure full control of the unit
during lifting.
