Overfill Warning

WARNING

DO NOT OVERFILL BIN. Stored grain, although heaped in the center, should
be no higher than the roof eaves at the outer edge. (See Figure 2A.) Filling the bin
above this point creates excessive internal pressure and may cause swelling and
eventual roof failure. The overfilling of a bin may also cause the blockage of roof
vents and eaves, which will lead to a build-up of air pressure causing roof damage.

Guidelines for Proper Storage of Grain Bin Materials Prior
to Construction

Storage of the build materials prior to construction is important. Do not to allow moisture to remain
between sheets or panels.

Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If
moisture is present, it must not be allowed to remain between the sheets. Separate the sheets or panels
immediately and wipe them down. Spray with a light oil or diesel fuel.

If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so
that they are raised above the ground and vegetation. Any stacking and spacing materials should not be
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the
bundles if possible.

Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they
do not fall over and cause injury.

If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize
the adverse effect upon the galvanized coating.

3. General Overview

Guidelines for Construction Procedures and Lifting Jack Usage

The following procedure is a guideline when using the required lifting jack. Follow this general guideline
when lifting the bin as sidewalls are being installed.

NOTE: The roof and the top ring for odd ringed bins or the roof and 2 rings for even ringed bins, will be

installed prior to the beginning of bin lifting procedures. Refer to all other procedures on sidewall
and stiffener installation prior to the start of construction.

IMPORTANT: Begin building with the bin oriented for doors and material handling equipmen t to be in the

correct position when bin construction is complete.

1. Consider the starting location of the bin, relative to the location of doors and other accessories.
Proper placement of lifting jacks in relationship to anchor bolts could make a difference in final
locations. Note that the sidewall sheets will be staggered.

2. The bin is lifted by the use of lifting jacks. Lifting jacks are used to slowly and evenly lift the bin during
construction. Lifting jacks must be properly sized and designed to carry all loads and job site
conditions associated with the construction of the bin.

The number of lifting jacks required is best determined by personal experience and expertise.
Factors such as bin size, jack design, construction conditions, support surface, etc., are all to be
considered when deciding how many to use. If in doubt, use one jack on every sheet. The lifting jack
must be adequate to carry all loads. Heavy duty jacks, generally hydraulic or electric powered in the
case of large bins, should be used for commercial installation. All jacks should be secured with
braces or otherwise maintained in a stable condition.

Lifting of the bins should not be done under windy conditions.
Follow the jack manufacturers recommendations on capacity and operations.

3. Lifting brackets should be attached through the stiffener bolt holes. Normally you will need to attach
to at least four (4) bolts per stiffener.

4. Raise the bin just high enough to assemble the next ring. When lifting the bin, all jacks must lift at
an equal rate. Monitor the lift to ensure even lifting is occurring.

5. To the inside of the first ring, bolt the next ring. Be sure to stagger the sheets and select the proper
gauge material.

6. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.

7. Attach stiffeners to the body sheets every two (2) tiers (on the external surface of the bin). You may
want to leave sheets loose to make the attachment of the stiffeners easier.

8. Now re-bolt the lifting brackets to the lowest ring in place thus far. Continue ring additions by
repeating Step 5 and Step 6.

9. Add inside and outside ladders as you continue to raise the bin. (Refer to the manual supplied with
the ladder).

10. Lower the tank and secure to the foundation before leaving the job site.

11. At the completion of the tank, set stiffeners over the anchor bolts and measure the tank to ensure it
is in a round condition. Consult with GSI for questions on tolerances.

NOTE: For 2 ring doors or vehicle traffic doors, special placement issues may apply. Consult the special

instructions provided with 2 ring doors or vehicle traffic doors for these options.

3. General Overview

Guidelines for Placement of the Decal Sidewall Sheet

Use the following as a general guideline the proper decal sheet placement.

NOTE: Refer to the stiffener to sidewall attachment detail and specif ic gauge sheet for the bin. The decal

sheets are located in the third ring from the top. They are to be spaced evenly around the diameter
of the bin.

Caulking Detail for Standard (Non-Laminated) Sheets

To keep out moisture from overlapping the sheets, it is necessary to apply caulk to each sheet prior
to installing.

NOTE: Always assemble the sidewall sheets with the overlap in the same direction.

1. Apply a strip of caulk near the outside edge of the outer sheet and between the outer two (2) rows
of bolts (A), then apply a strip of caulk 10" (25.4 cm) long along the horizontal se ams (B), as shown
in Figure 5A.

1. When assembling two (2) assembled laminated sheets to each other, apply a strip of caulk (A) near
the outside edge of the outer sheet, between the outer two (2) rows o f bolts and outside the last ro w
of bolts. (See Figure 5C on Page 34 and Figure 5D on Page 35.)

2. Place a strip of caulk (B) 12" (30.4 cm) long to each the horizontal seams. (See Figure 5F.)

NOTE: Before bolting the next ring into place, apply a strip of caulk 12" (30.4 cm) long on the front

of the under lapped sheet at each joint.

3. Also, a 12" (30.4 cm) strip of caulk is to be placed along the lower horizontal edge of the lapping
sheet at the vertical seam. This will fill the space that occurs between the holes caused by the
overlapping sheets.

When assembling two (2) sheets to make a laminated sheet assembly (C), apply a row of caulk all around
the vertical seam. (See Figure 5F.)

Use the supplied tube caulk to fill the larger gaps that occur with heavier gauges and laminated sheets.

Ref # Part # Description Length Available Gauges

A CTS–2091XX Stiffener Splice 10" (25.4 cm) 8, 10, 12, 14

Use the following chart to determine the gauge of the splice, which is determined by the gauge of the
stiffeners that are being connected. If connecting a heavier gauge to a lighter gauge stiffener, always use
the heavier gauge splice for the 13 to 12, 8 to 6 and 2 to 0 gauge connections.

For example: If connecting a 13 gauge stiffener to a 12 gauge stiffener, use the 12 gauge splice. If
connecting an 8 gauge stiffener to a 6 gauge stiffener, use the 10 gauge splice. If connecting a 2 gauge
stiffener to a 0 gauge stiffener, use the 8 gauge splice.

7. Base Angle Installation

Installing the Base Angle

Installing the base angle ring will help reinforce and seal the final ring.

What You Should Know

The base angle overlap should be offset two (2) holes from the stiffener. Do not place overlap in line with
the stiffener.

1. Place a section of the base angle (B) to the bottom portion of the final ring (A).

NOTE: The sidewall sheet will sit on top of the base ang le with the vertical po rtion of the base angle

on the inside of the bin. And each end of the base angle will connect to the next base
angle section.

2. Install bolts (C) and nuts (D) as shown, but leaving the end holes of each section unfilled until the
next section is to be installed.

3. Attach the next base angle section overlapping the end holes (E) and install bolts (C) and nuts (D).

4. Repeat this procedure for the remaining base angle sections (B) over lapping the previously installed
base angle section.

5. Before the bolts (C) are tightened, push the base angle tight against the bottom edge of each sheet.

6. Tighten the hardware to the recommended torque specifications, see bolt torque specifications

on Page 24.

7. Before lowering the bin, apply the optional mastic sealer strip (F) to the entire underneath side of the
base angle.

NOTE: If optional mastic sealer strip is not used, it is recommended that some other met hod should

be utilized to seal the base ring to the concrete.

8. Lower the bin onto the foundation and check for an adequate seal. (See Figure 7A.)

7. Base Angle Installation

Installing the Base Angle Shims

A section of the base boot plate will rest on top of the base angle, therefore causing the base boot to rest
unevenly on the foundation. To offset this, base angle shims are required to ensure the base boot sets
evenly on the foundation.

What You Should Know

1. Place the required base angle shim around the anchor bolt next to the base angle.

2. Place the base stiffener over the anchor bolt onto the required shim.

3. If needed, add standard shims under the required base angle shim. (See Figure 7C.)

NOTE: If more than one additional shim is required, then the shims must be welded together to the

base plate or the base plate must be grouted to provide the proper elevation.

8. Instructions

Stirring devices may create additional loads on grain bin sidewalls, roofs and
floors. If high-moisture grain is loaded too deep and too fast, unstiffened bin
walls can become overloaded. Observe the following installation and operation
procedures if the bin is to be equipped with the stirring device.

WARNING

Instructions for Stirring Devices

Bins are offered in more than one structural series for specific uses. To maintain the warranty, the
appropriate “series” grain bin must be used. Consult the sales catalog or contact the Engineering
Department for current recommendations. Note that the use of any stirring device with three (3) or more
vertical screws may require a heavier than “standard” series bin. Any re-circulating device or system
should be used in the “re-circulating” series bins. NOTE: For GSI bins larger than 36' diameter an

alternate method of mounting is to attach suspension chain to intermediate center collar.

1. Read owner’s manual for the stirring device and follow all instructio ns set forth by the manufacturer.
IMPORTANT: Install the switch for the stirring device near the roof manway opening so that the

unit can be observed while stirring.

2. Make sure there are no obstructions, such as protruding ladders.

3. After loading approximately 3' of grain, run the unit one complete revolution to determine if it is

working properly.

4. If the unit is functioning properly, operate the stirring device continuously while filling and drying to

avoid compacted grain around the vertical screws.

5. If it becomes necessary to stop a stirring device using laterally moving screws, try to stop it with the

vertical screws nearest to the center of the bin, away from the sidewall. Should a device stop or stall
for any reason and remain inoperable for any length of time, the auger carriage should be supported
to the grain surface before restarting. The vertical auger should be turned by hand, with a pipe
wrench, before power is applied.

6. For best results, fill the bin to one-half of the final intended depth. Dry grain to 16% and continue

filling. Use filling rates specified by stirring device manufacturer. If necessary to fill to the top without
stopping, reduce the filling rate and drying air temperature so that the stirring rate can kee p up with
the drying rate.

7. Do not overfill bin. Filling should be stopped at bottom of top ring or 30" below the track.

8. The preceding steps are only general instructions which apply to the majority of stirring devices.

Since there are different manufacturers of these devices, it is important to read the operator’s manual
thoroughly for specific instructions applicable to the machine.

11. Roof Assembly

Roof Assembly

After completing the first sidewall ring, you are ready to begin construction. Begin with the center collar
sections. For convenience in opening and closing the center cover, the roof ladder and manhole sheet
should be placed directly opposite the two (2) slide rod holes in the center collar. Next build a roof center
support to hold the peak in place at the proper height. A simple structure composed of a sturdy cross
arm attached to a pole and supported by a platform or scaffolding will do. Stand the center support directly
in the center of the bin. The following dimensions are approximate distances used in bin roof construction.
Adjusting the center support height will ease roof erection. Place eave clips inside the bin wall to maintain
an opening around the top of the sidewall. This allows condensation, which normally collects on the
underneath side of the roof panels, to flow freely to the outside of the bin, thus avoiding possible
grain spoilage. (See Figure 11A.)

NOTE: Use the same overlay procedure on all roof sheets.

For best results in erecting the roof, install two (2) roof panels in four (4) places as shown in Figure 11C.
When these eight (8) panels are in place, the peak assembly should be centered. Next add two (2) or
three (3) panels at a time to each section making certain to la p them the same way, until all panels are in
place. Be sure the panels are bolted loosely. DO NOT TIGHTEN BOLTS UNTIL THE ROOF IS
COMPLETELY ASSEMBLED. When installing the roof panels, take into consideration placing the
manway for ease of access to and from the sidewall and roof ladders. On Stiffened tanks, particularly

location of the manway panel and roof ladder in relation to the stiffeners is crucial for proper
installation of the ladder system. PNEG-1420 and PNEG-1738 for flat bottomed stiffened tanks.
These manuals are packaged with the ladder and safety cage packages.

Fasten roof sheets to eave clips and sidewall sheets as you assemble.

12. Support Ring Instructions

WARNING

DO NOT OVERFILL BIN. Stored grain, although heaped in the center, should
be no higher than the roof eaves at the outer edge. Filling the bin above this
point creates excessive internal pressure and may cause swelling and eventual
failure of the roof.

Ring Instructions

Be sure to install ladder rungs and safety steps as you assemble roof panels. (See Figure 12A.) At this
point you will have completed assembly of the roof. Do not tighten bolts yet. Optional equipment and
accessories should now be installed.

NOTE: When assembling such pieces as roof ladder rungs, use 5/16" x 1" bolts with a flat washer on

top of the slot and extra neoprene washer between the roof and the piece being added. This will
ensure a more protective seal against moisture.

IMPORTANT: Maximum weight to be supported and/or suspended from the roof is to be 6000 pounds

for 18' through 36' (non-trussed) ONLY.

IMPORTANT: Maximum weight to be supported and/or suspended from the roof is 10000 lbs. for

commercial (trussed roof) 36'-60' flattop roof bins. Roof loads should be supported from
the flattop or at the second lower “Z” collar.

Roof Support Ring Instructions

Roof support rings are standard on all bins up to 48' diameter. Two (2) support rings are standard for 42'
and 48' diameter bins. All support rings will be placed on the outside of the roof panels.

To determine the location of the support rings, start at the narrow or peak of the roof panel and count
each hole. Having counted down the required distance, as described in the Chart below, install the
appropriate brackets. (T=Top, B=Bottom)

Expansion bolts should be fully contracted when assembling support rings. When you have completely
assembled both rings, (but prior to expanding the bolts) tighten all roof bolts including eave clip bolts.
Now extend expansion bolts by running the nut out on the threads. This procedure should be continued
evenly around the roof until the ring raises the roof to show a slight crown.

Support ring expansion bolts may become dislodged from the ring during high winds or when the inside
pressure of the bin is too great. If one expansion bolt is dislodged, the entire ring will become useless.
To prevent this, drill holes through the support ring and expansion bolt (after the rings have been installed
and expanded to the correct size) and insert a cotter pin or bolt through each hole.

NOTE: Welding of the expansion nuts to the pipe and expansion bolts or staking the expansion bolt

threads to prevent the movement of the jamb nut may be done as a n option to drilling and pinning.

Support rings as shown on Page 85, are optional equipment. Support rings are optional for 54' diameter
tanks and 42'-48' tanks with a roof.

To determine the location of the safety rings, start at the narrow or peak of the roof panel and count each
hole separately. Count down the required distance and install the appropriate brackets. See Table on

Page 85 for proper location.

Expansion bolts should be fully contracted when assembling safety rings. When both rings are completely
assembled, but are not yet expanded, tighten all roof bolts including eave clip bolts. Now extend expansion
bolts by running nut out on threads. This procedure should be continued evenly around the roof until the
ring raises the roof to show a slight crown.

Safety Suggestion: Support ring expansion bolts may become dislodged from the ring d uring high winds
or when the inside pressure of the bin is too great. If one expansion bolt is dislodged, the entire ring will
become useless. To prevent this, drill holes through the support ring and expansion bolt (after the rings

3. Install the eave clips as shown on Page 91. Every third clip should be located at a roof stiffener.

NOTE: The eave clip bolt and nut must be reversed (bolt head on the inside) at the top stiffener
for clearance.

4. Roof trusses should be assembled into complete rafters for installation. This should include the roof
truss sections, roof splices, truss channel brackets and roof stiffener clips. Tighten all splice bolts with
trusses positioned to create a straight truss. (Straight truss assemblies with tight connections will
prevent possible problems in later construction.)

5. After placing the “Z” collar at the correct center height, begin installation of the truss assemblies.
Attach a roof truss assembly to a roof stiffener bracket with a partially tightened bolt. Raise the top
of the truss assembly and bolt to the “Z” collar using 5/16" x 1" bolts (do not tighten the bolts at this
time). Be sure to use 5/16" washers on the slots in the truss clip. Complete bolting to the roof stiffene r
bracket. The truss assembly must be stabilized at this point.

6. Place two (2) roof sheets on the truss assembly, one on each side of the rafter. The 5/16" x 1" bolts
in the “Z” collar must be removed and replaced through each roof sheet as they are positioned.
Use 5/16" x 1" bolts to connect the roof sheet ribs to the truss assembly. Be sure at least two (2)
5/16" x 1" bolts are placed in each roof sheet at the eave clip connections. These roof sheets will
stabilize the roof truss and center “Z” collar assembly.

7. Repeat Step 5 and Step 6 on the opposite side of the bin and then at the one quarter position
around the bin until four (4) rafter assemblies are erected with two (2) roof sheets each at four (4)
equally spaced positions.

8. Connect the remaining rafter assemblies. Truss channels should be installed with each additional
rafter assembly. Tighten the bolts on one end of the channel with the channel positioned as close as
possible to the roof rafter splice. This will stabilize the truss assembly and hold it in a vertical position.
Install the tension rods as shown in Page 91.

9. After completing the rafter system with all truss channels installed, the remaining roof sheets may be
bolted on the trusses. Be sure to install all roof ladder steps, intermediate eave clips and any other
necessary accessories.

10. Install the flattop as shown in Page 92. For bins with a dome cap option, the small center collar, roof
flashing and roof cap assembly can be installed as a complete unit. Be sure to tighten all connections
in the roof rafter system and related parts.

nd

11. Apply the peak load on the flattop on the second (2

), lower “Z” collar.

Temperature Cable Support (CRP-5286) (42' and 48' (12.80 m and

14.63 m) Support System)

1. All packages (42' and 48' (12.80 m and 14.63 m)) shall span three (3) roof panel as shown in

Figure 15A on Page 94.

2. One package should be provided for each cable in the tank with the exception of the center cable.

3. The 42' and 48' package includes bracing angle for the roof rafters, hanging angle and a cable
support channel.

4. Each set of rafters should carry only one temperature cable.

5. Once the roof system has been installed, installation of the cable support packages may proceed as
follows.

6. For 42'-48' bins, center the support angle and drill the holes to bolt the support angle (CRP-5185
(42' and 48') (12.80 m and 14.63 m)) into the roof rafter (See Figure 15B on Page 94 (42' and 48')
(12.80 m and 14.63 m) to locate which holes to drill.) and attach with 3/8" diameter bolts. Support
angles may be installed on the outer surface as indicated in Figure 15B on Page 94.

7. Should the angle location be such that the rafter splices coincide with angle placement, the angle
(CRP-5185) should be slid one way enough to align the angle holes with the splice bolts or miss the
splice bolts.

8. Slight adjustments of the radius may be necessary to ensure that the channel support angle holes
and cable support channel holes will correspond. Field drill the holes in the ro of rafter for the hanging
of the channel, as illustrated in Figure 15C on Page 95.

9. Once the rafters are in place, field drill the holes to bolt the su pport an gle (CRP-5786 or CRP-5787)
into the roof rafter and fasten with 3/8" bolt. (See Figure 15C on Page 95.)

10. Attach the cable attachment bracket (CRP-5213) in the center of the support channel (CRP-5285) as
illustrated in Figure 15C on Page 95 and hang the cable.

11. If it is desired to support the cable from the flange of the support channel (CRP-5285), it will be
necessary to reinforce the flange with a 12" section of 3" x 3" x 3/16" angle.

12. No more than one cable should be supported from a pair of roof rafters.

13. This package will allow a maximum radius of: (42' equals 16.86') (12.80 m equals 5.14 m), (48' equals

19.22') (14.63 m equals 5.86 m). These radii represent the maximum radius that the cross members
will span. These are not recommended installation locations. Install according to the temperature
cable manufacturer’s recommendations. For a greater radius, the recommendation shown in this
manual for temperature cable installation must be used (using field cut, hot rolled sections), however
a rafter support package must be used.

Installing Wind Rings

Installation of wind rings is similar for a 2 and a 3 post bin design, although hardware quantities may vary.

What You Should Know

Before installing, determine the bin size, sidewall gauge thickness and height. Use the hardware chart to
match the correct bolt length with the correct sidewall gauge thickness when installing the wind ring
brackets to the stiffeners. (Refer to hardware requirements chapter on Page 22.) To determine the
location of the wind rings or if additional wind rings will be needed for sidedraw systems, see wind ring
requirements for sidedraw systems.

PNEG-4042 40 Series 42' and 48' Diameter Bins 99

17. Accessories

NOTE: When installing the wind ring bracket to a 2.66" close

punched stiffener, use the bolt holes marked 1, 2, 4 and 5 as
shown. When installing the wind ring bracket to a 2.66" far
punched stiffener, use the bolt holes marked 1 and 5 only.
Hole marked 3 will not be used on all 2.66" bins. Flange bolt
hardware length may vary with sidewall gauge thickness.

Installing Wind Rings (Continued)

1. Install a wind ring bracket (B) to each stiffener (C) using flange bolts (A) and flange nuts (D).

Figure 17C Wind Ring Bracket

2. Tighten hardware to the recommended torque specifications. See bolt torque specifications

on Page 24.

3. Place a wind ring section (E) into the channel of the wind ring bracket (B) and install a C-clamp (I),
securing with flange bolts (H) and flange nuts (J). Do not tighten until all wind ring sections
are installed.

4. Repeat this procedure, inserting each wind ring section (E), over the previously installed wind ring
section, securing the wind ring sections together with flange bolts (F) and hex nuts (G).

5. Before installing the last wind ring section (E), slide a wind ring couplin g collar (K) over the wind ring
section (E).

6. Install the last wind ring section (E) and cut the wind ring section to the proper length.
NOTE: The cut needs to be made in a location that allows minimal space between the pipes.

7. Slide the wind ring coupling collar (K), aligning the three (3) pre-drilled holes and install flange
bolts (F) and hex nuts (G). Field drill the remaining three (3) holes (L) using the wind ring coupling
collar (K) as a guide or template. (See Figure 17D on Page 101.)

8. Install the remaining flange bolts (F) and hex nuts (G) and tighten all hardware to the recommended

100 PNEG-4042 40 Series 42' and 48' Diameter Bins

torque specifications. See bolt torque specifications on Page 24.
