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.
• Equipment is top heavy. Use caution when lifting/
moving equipment to prevent unit from tipping.
• 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.
• The high center of gravity on this unit requires the
use of an anti-rolling cable (chain or sling). To prevent
unit from rolling, attach cable (chain or sling) with no
tension and minimal slack around compressor
suction pipe as shown.
• Do not use forklift to move or lift unit unless unit has
lifting base with.
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.
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.
