Crane Bracket Placement
Install the Crane Brackets onto the modules if not already installed.
Crane Bracket Location
Base Modules and Middle
Modules utilize four crane
brackets. Brackets mount to
stack module support pads.
Lifting usually occurs between
the 2nd column from fan end to
the 6th column from fan end.
This will vary with model
number.
The module should remain
parallel to the earth as it is
lifted.
Base Module crane brackets
Top Modules utilize 2 crane
brackets with 4 lifting points
and a spreader bar between.
These mount to column seams
on the roof screen.
Lifting usually occurs between
the 2nd column from fan end to
the 6th column from fan end.
The module should remain
parallel to the earth as it is
lifted.
A crane of sufficient lifting
capability should be used.
Loads of 5,000 to 15,000
pounds should be expected.

Setting Lower Module on Pedestals
Personnel working around this equipment while it is lifted into position must use extreme caution. Lifting equipment (crane and rigging) must be of proper lifting capability
for the unit size and weight. All local safety precautions and procedures must be followed.
1. Install stiffeners and service platform in accordance with PNEG-349REV. At each stiffener/
pedestal location remove the 1/2” bolts and nuts
that attach the dryer frame leg to the frame rail.
Use that hardware to attach a stiffener base connector clip (D01-1045).
BE ALERT!
D01-1045
2. Lift base module and position it in the location
the dryer is to occupy. NOTE: Crane brackets
may need to be adjusted to ensure that the
module will be parallel to the ground when
lifted. With the base module in position bolt a
pedestal to each stiffener base connector clip using 3/8”-16 x 1 1/2” bolts (S-7928).

3. With a stiffener splice (SS-7053), splice the
pedestal to stiffener at each pedestal location. Now
make sure any nuts and bolt used so far have all
been tightened.

When splicing pedestal to
stiffener use 3/8”-16 X 1 1/2”
bolts (S-7928) where circled,
use 3/8”-16 x 1” (S-7927) in all
other holes.

Anchoring Lower Module to Foundation
4. Set the lower module into final position and
check level. Use shims (SS-6953) to level lower
module if needed.
Shims
5. Anchor lower module to foundation. If anchor
bolts were not set when the concrete was poured,
then drill holes in the foundation to accept anchor
bolts (use 3/4” x 9 5/8” minimum anchors with
epoxy resin).
GSI has 1” x 12” anchor bolts (Part no. S-8957),
tubes of epoxy (GTC-0004), and mixing nozzles
for epoxy tubes (GTC-0005). An epoxy gun will
be needed.

7. NOTE: If the dryer is a twenty foot dryer
then this step is not required. Use 1/2”-13 x 1
3/4” bolts (S-3883), and 1/2”-13 lock nut (S-6493)
to attach support leg assemblies to rear corners of
the dryer frame. Use the grey shim (D01-1221) to
fill the gap between the support leg and dryer
frame. On the right side it may be necessary to
remove the cotter pin and slide the clean out door
pivot rod forward enough to insert the top bolt.

9. Attach a frame tie down (D61-0011) at each of
the corners of the upper module frame using existing and supplied 1/2” bolt (S-3728), washer (S-
2120), and nut (S-6493) as shown in photos above.
10. Lift upper module and move into place over
lower module. Use a guide line to keep module
steady while it is being moved.

11. Once upper module is in place over lower
module slowly start to lower upper module while
making sure that the frame tie downs (D61-0011)
come down to the outside of the module support
pads they will later be bolted to. Also you will
notice that the connecting section end (factory installed) has a tab that extends below module frame,
this tab will slide into the lower module just behind the plenum end panel.
12. When the upper module is set in place and
the crane is bearing none of the weight check the
upper module for level. It may be necessary to
shim the upper module to level it. If the upper
module is not level then place module support
shims (D61-0089) on the module support pads (it
may be necessary to raise the upper module a little
to place these shims).

13. Once the upper module is set and level use
1/2”-13 x 1 1/2” bolts (S-3728), 1/2” washers (S-
2120), 1/2”-13 lock nut (S-6493) and bolt the
frame tie down (D61-0011) on the upper module
to the module support pad of the lower module.
14. Use 3/8”-16 x 1” (S-7927), 3/8”-16 nut (S-
968), and a stiffener splice (SS-7053) to splice the
stiffeners of the lower module to the upper module.
15. Use 3/8”-16 x 1” (S-7927), 3/8”-16 nut (S-
968) to connect the top angle bracket of the lower
module to the frame tie channel of the upper module. There may be a small gap between these two
parts, if so, the 5/16” bolts connecting the top angle
bracket to the lower module can be loosened just
enough to adjust the height of this bracket (the
holes are slotted). Be careful not to loosen the
bolts too much because as you will see there is no
convenient way to get to the nuts on these bolts.
If the bolts are loosened just enough to adjust this
bracket they can be retightened without having to
hold the nut on the other side.

Appendix B - Ladder Cage Installation
1. To install the safety cage for the rear ladder of the bottom
module first connect two large bell hoop halves together
(LS-4352) together , and connect two small bell hoop halves
(LS-4351) together. Then attach a safety cage bracket (LS-
4349) to each end of those assemblies. Use 5/16”-18 X 3/4”
bin bolts (S-275), and 5/16”-18 nuts (S-3611), see photos at
the bottom.
2. Use five 44” safety cage vertical supports (LS-4353) and
connect the small and large bell hoops assembled in the previous step using 5/16”-18 X 3/4” bin bolts (S-275), and 5/
16”-18 nuts (S-3611). NOTE: Leave one side of this as-
sembly open so the rear access door on the dryer will
not be obstructed.
3. Now locate the safety cage bolt holes on the ladder (see
photo right). Use 5/16”-18 X 3/4” bin bolts (S-275), and 5/
16”-18 nuts (S-3611) to install safety cage onto the ladder.
