Mechanical Installation of a
Remote Floor-Mounted AFDH
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 AFDH 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.
1. Ensure that the section of floor or concrete pad that has
been prepared as the installation location for the
remote floor-mounted AFDH drive unit is as level as is
possible.

2. Prepare lifting equipment and rigging.
a. Depending upon the model type, a unit-mounted
AFDH can weigh up to 1400 pounds. Confirm the
weight of the AFDH unit to be installed. Refer to
Table 7, p. 20.
b. Verify that the intended lifting device and rigging
has the capacity to safely handle the load before
hooking up to the two factory provided lifting points
on top of the cabinet assembly.
c. Use the appropriate rigging techniques to ensure
that the cabinet assembly will be balanced about its
center of gravity during lifting. Refer to
"Recommended Rigging and Lifting Procedures for
AFDH Drive Units," p.
3. Using safe lifting practices, carefully lift the cabinet
only as high as is necessary to provide enough
clearance to allow attaching the previously assembled
corner brackets to the base of the drive cabinet.
a. Secure the corner brackets to the base of the drive
with the remaining hardware provided in the
bracket kit.
4. Carefully maneuver the drive assembly into position
over the floor section or concrete pad it is to be
installed upon.
5. Slowly lower the cabinet and set it gently onto the pad,
but do not detach the lift rigging at this time.
a. Using the angle bracket foot at each corner bracket
location as a template, mark the hole locations for
the locally supplied concrete anchor bolts that will
be used to secure the entire drive assembly to the
floor.
Note: The slots in the angle bracket feet can
accommodate up to a 0.625 in. diameter
concrete anchor bolt.
b. Lift the cabinet up and temporarily move it out of
the way so the anchor bolt holes can be drilled.
c. Move the AFDH cabinet back into position over the
pad and gently lower it into place with the holes in
the feet lined up with the drilled anchor bolt holes.
Leave the lift rigging in place until the cabinet is
properly secured to the pad using locally supplied
concrete anchor bolts.
d. Confirm that the drive cabinet is firmly anchored to
the pad and is stable before detaching the rigging
from the lifting points.
