PROPER LIFTING WITH SHACKLES
Shackles are fastened to a sling or chain, which is used
to lift and lower the sections in a tiered AHU. Refer to
the following figures for proper lifting:
•
for proper lifting with a
hook and shackle at the corners.
•
for proper lifting with a
hook and shackle at the lifting lugs.

Figure 9 -
Proper Lifting with Shackle with Corner
Connector Corners
An experienced and reliable rigger must handle the un-
loading and final placement of the AHU, and must be
advised of the following:
• AHU contains internal components and should be
handled in an upright position.
• Care must be exercised to avoid twisting the
equipment structure.
• Prevent unnecessary jarring or rough handling.
Proper rigging and handling of the
equipment is mandatory during unload-
ing and setting it into position to prevent
voiding the warranty.
Use the proper spreader bars and hoisting lines when
rigging to prevent damage to the AHU casing.
When lifting long AHUs, a special system must be used
to insure a minimum 60° angle between the lifting lugs
and spreader bar/frame
.

USING FORK LIFT IN SPECIAL
CIRCUMSTANCES
Forklifts should not be used to off-load AHUs except in
special circumstances. If moving an AHU with a fork lift
or similar equipment becomes necessary, make sure
the lifting forks are long enough to reach from the fork
truck to the opposite side and slightly beyond the AHU.
Leave the shipping blocks attached to the bottom of
the AHU until it is moved to its final location. There is
no structural support under the equipment except what
is visible from the perimeter.
