2. Safety
Proper Storage of Grain Bin/Silo Materials Prior to Construction
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.

4. General Information
Bulk Feed Tank Assembly Manual General Instructions
First, read the Assembly Manual completely before starting to assemble your Bulk Feed Tank. Check your
shipment with the packing list to be sure there are no shortages.
1. Decal protective mask must be removed when assembling tank. Mask may become difficult to
remove if left exposed to sunlight.
2. Vertical seams must be staggered on all sidewall rings.
3. When legs extend up 2 rings, the leg holes must be in alignment in the bottom 2 rings.
4. All hopper seams and the hopper collar use truss head bolts. The heads of the bolts must be on the
inside of the tank.
5. Hex head bin bolts are used on all sidewall and roof seams with the bolt heads on the outside of
the bin.
6. Hex head bolts are to be used on all leg to sidewall connections with the bolt heads on the inside of
the tank.
7. All bolts are to be tightened from the nut side only. Do not allow bolt heads to spin.
8. 7' Diameter sidewall sheets must be bolted together so there is 65-5/8" between leg holes.
(See Page 80.)
9. Drift punches can be used to align holes.
10. All vertical sidewall sheet seams must be overlapped in the same direction.
11. A hole spacing of 3-1/8" is used at the top of all top sidewall sheets and at the bottom of all bottom
sidewall sheets.
Selecting the Proper Site
The selected site should be level, firm and free from underlying debris. The tank can be installed
satisfactorily on slopes, but as the slope increases, additional labor and materials are required for the
foundation. The concrete foundation surfaces must be level
and tamped thoroughly to prevent uneven settling from the weight of the tank. Good water dra inage should
be provided to prevent water collecting under or aro und the tank. The site must allow convenient access
for loading and unloading and provide additional space for future units. Also, consider the positioning of
handling equipment, availability of electricity, etc.
. If some fill is required, it should be watered
Tools
Tools recommended for assembly of Bulk Feed Tanks.
1. Assorted sizes of combination wrenches
2. Hammer
3. 3-12" Long drift punches
4. 1 Large flathead screwdriver
5. 1 Pair of slip joint pliers

The chart labeled “Sidewall Sheet Gauge Chart” is for the reference when building the tank. This chart tells
you what gauges your rings of the specific tank must have. To read the chart find up the tank size you are
building, for example, a 7' diameter tank with 7 rings is referred to as BFT 7'-7 ring. The side labeled
“Gauge” will indicate which sidewall sheets to use. The sheets are color coded, simply match the gauge
number with the color. (Use “Sheet Gauge Color Code Chart” below.)
NOTE: Sidewall sheets are color coded on edges for gauge identification.

Sidewall Sheet Orientation
IMPORTANT: Ple ase note sheet orientation when assembling the bin sidewall. The upper right corner will
have a slot or identifying sticker. This corner should be on the inside of the tank when
assembled. (See Figure 6C.)
Figure 6C
Sidewall Assembly
Start by assembling the top ring of the Bulk Feed Tank. The top row of bolt holes has 3-1/8" spacing in
the top ring. Before bolting the sidewall sheets together, check that you have the proper gauge steel for
the top ring. The higher gauge number denotes thinner materia l. For example, 20 gauge material is thinner
than 14 gauge. In assembling all Bulk Feed Tanks the thinnest material always go on top. The heaviest
corrugated sidewall sheets will be located on the bottom of the tank. Check the various gauges of the
tank with the “Sheet Gauge Color Code Chart” and “Sidewall Sheet Gauge Chart”, on Page 23. Begin
by putting the rings together on the edge of the sheets. After the first ring is complete, the roof must be
assembled as described on Pages 26-27. After the roof is assembled, the tank can be rolled on its side
for easier sidewall assembly. (See Figure 6F on Page 27.)
Tighten all bolts from the nut side only.

6. Sidewall Assembly
First ring assembly. Tighten
bolts from the nut side only.
Continue to add rings with lighter gauges first, then heavier gauges. Each subsequent row of sidewall
sheets goes to the inside of the previous row of sidewall panels. Remember to place the caulking between
every ring. See Figure 6D for illustration of proper sidewall overlap and caulking detail.
Be sure to stagger all vertical seams between rows.

6. Sidewall Assembly
IMPORTANT: Begin bolting in the center of sheets when connecting sidewall rings to one another.
When bolting sidewall rings to one another, always begin bolting in the center of the sh eet and work toward
the outside edges (horizontal seams). This allows the sidewall to draw up evenly.
Figure 6F Sidewall Assembly
It is easier to add more sidewall sheets with the tank on its side. It can be rolled easily from side-to-side
to allow the bolts and nuts to be put in the proper holes. NOTE: The roof must be assembled on the first ring before rolling it over to its side. This will not be practical on taller tanks where jacks should be used.

7. Roof
Sealed Roof Panels Installation
NOTE: The roof and sidewall ladders are centered on a roof panel. Be sure to apply two (2) strips of
caulking on either side of bolt holes at the seams. Roof panel edges allow for the roof to be assembled in
either the clockwise or counterclockwise manner. (See roof sheet overlap detail on Page 29.) Be sure to
lap sheets in the same manner around the entire tank.
Figure 7A
On bins that will be equipped with a pneumatic fill system (See Page 72), the two (2) roof panels with fill
hole and exhaust hole must be located opposite each other on the Bulk Feed Tank. The peak ring may
now be installed.

Do not raise tank near power lines. Electrocution could occur if the tan k came into
contact with live power lines.
WARNING
Raising Bin to Set on Foundation
Preparing Tank for Lifting Upright
Just before standing the tank upright, peel protective mask off the decal while it is easy to reach. Mask
may become difficult to remove if left exposed to sunlight.
Check for all possible overhead obstructions, power line, etc., BEFORE standing the tank on
the foundation.
To prevent damage to Legs when raising tank, brace them with 2" x 4 " (50mm x 100mm) pieces of wood
as shown in the illustruction. See the chart for the correct length.
Some tanks may be built on the side and raised upward. For some taller tanks (9 rings and taller) it is
recommended the sidewalls be assembled using bin jacks and the final lifting be done with a crane.
(See Pages 68-69.)
In any case, proper precautions with rigging, lifting, or raising procudures should be followed to ensure
that personal safety is not compromised and the tank is not damaged.

Anchor Tank Before Second Ring Assembly
Anchor all jacks securely with metal stakes and cables (use one jack per sidewall sheet). Now raise the
tank just enough to assemble the next ring. When lifting your tank crank all jacks at an equal rate. This will
prevent bowing previously assembled rings and make for easier hole alignment. To the inside of the first
ring bolt the next ring. Be sure to stagger the sheets and select the proper gaug e material. Lower the tank
on the foundation after assembling and tightening bolts on each new ring. Now re-bolt lifting straps t o the
lowest ring in place thus far.
NOTE:Add outside ladders and other accessories to tank walls as you continue to raise the tank.
After body sheets are assembled and bolts are tightened, raise the tank and attach the legs. Do not put a
bolt in the bottom sidewall hole yet, because the hopper must be attached here. When the legs are in place
and tightened, release the jack enough to rest the tank on the legs.

Lifting with Crane
Watch for power lines. The crane and anything associated with building the bin
(due to height) can get in the way of power lines.
WARNING
13. Raising Bin
Figure 13C
A crane of adequate capacity attached to a spider assembly with cables connecting at each vertical
sidewall seam just above the legs can also be used to lift the tank. Make sure the tank is being lifted
smoothly and evenly. Raise it enough to assemble the next ring and/or to attach the legs. Reference a
qualified rigger.

Anchoring Tank
Check all legs to see if shims are necessary to level the tank properly. After bulk feed tank is level and
shimmed properly, anchor the tank down with 5/8" washers and nuts. (See Figure 13D.)
Standa rd Hopper Tank Anchoring
Measure between opposite legs to be sure they are an equal d istance apart before securin g the tank with
anchor bolts.

Roof Panel
Identical pre-punched roof panels are available from the manufacturer for inlet and outlet sections of
pneumatic fill systems. Extruded lip of the panels provide for weather-tight installation. Caulking placed
between angle rings virtually eliminates all leakage problems. Rubber seal must be utilized at roof cap
area to prevent material “blow by” from pressurized systems.
To install fill kits in roof panels not pre-punched, cut 5-5/8" (143 mm) diameter holes in opposing roof
panels as shown. Caulk sufficiently to provide weather-tight seal.
Refer to PNEG-1904, that is included in the pneumatic fill kits for information on installation of the cap latch
and lid sealing components.
