Section 1 Grain Bin Specifications
1. GENERAL DESIGN INFORMATION
a) All Chief Industries grain bins are designed for storage and handling of 49.5 PCF (793 kg/m3) free flowinggrain (52.5 PCF (841 kg/m3) compacted grain @ 6%). Grain fill level shall not exceed 1" (25.4 mm) downfrom eave.
b) Storage of products other than grain (products heavier than 49.5 PCF (793 kg/m3),products having unusual f low characteristics or unusual corrosive properties) must beapproved by Ch ie f Indust ri es ' Engineering Department prior to quoting. Storage of soybean meal ormeat scraps or other non-flowing products in standard tanks will void the warranty.
c) Each individual sidewall ring has been designed to accommodate the vertical and horizontal wall loadsimposed by the stored grain. Sheeting gauge and design strength for each ring is individually analyzedfor all bin sizes. Also, stiffener gauges and design strengths are individually determined for each bin's fullsidewall height range. All steel materials are purchased in accordance with the applicable ASTMStandard.
d) All bolted connections are designed using high strength bolts which meet the specifications of theapplicable ASTM or SAE Standards.
e) All bins must be filled uniformly at the center and unloaded through the center discharge only, until grainno longer flows by gravity. Bins filled or emptied off-center will void the warranty; except approvedsidedraw systems.
f) All Galvanized Steel used for storage and drying bins conform to ASTM specification A653 and theGalvanized coating to A924, TYPE G-115; 1.15 oz/ft.2 (Z350; 350 gm/m2) total for both sides as follows:

The CB Stiffened to Eave Bins may be used for all common drying applications, thesebins are available in sizes CB #5 thru #16. If stirring devices consisting of more than sixdown augers are to be used, contact Chief Industries, Inc., for recommendations. This binmust be used when Stirway II's, Recirculating devices, and stirring devices with four ormore down augers are to be installed.
Note: See detail on using Stirring Devices
4. THE GENERAL CONTRACTOR'S RESPONSIBILITIES
It is the responsibility of the General Contractor to insure that the complete bin system (bin,foundation, grain transport equipment, aeration equipment, and other accessory equipment) isconstructed in a quality workmanship manner and that all equipment is installed per the respectivemanufacturer's instructions.
In addition, the General Contractor is responsible for the fitness of use of any system which heconstructs. All accessory equipment incorporated into the system should be approved for theintended use of each respective equipment manufacturer.
a) Field Modifications and Erection Defects
Chief Industries, Inc., assumes no responsibility for field modifications or erection defectswhich create structural or storage quality problems. If any field modifications arenecessary which are not specifically covered by the contents of our erection manual,contact Chief Industries, Inc., for approval of the field modifications. Any unauthorizedmodification or erection defect which affects the structural integrity of the Chief bin will because for immediate nullification of the Chief Grain Bin Warranty.
b) Concrete Information for Design and Construction
The suggested foundation designs shown in the bin erection manuals are based on theallowable soil bearing capacity of the undisturbed soil and should be checked by alicensed engineering firm. Using soil borings to determine the allowable soil bearingcapacity, a professional engineer will need to be engaged by the contractor to design thefoundation and floor slab accordingly. All suggested foundation designs must beapproved by a licensed engineer in order to meet local governing building codes and localsoil and weather conditions. Wall loads and floor pressure for standard Chief grain binsare available from Chief Industries, Inc., upon request.IMPORTANT: THE FINISHED FLOOR SURFACE MUST BE LEVEL AT THE BIN WALLLOCATION. LOW SPOTS IN PERIMETER WALL ELEVATION WITHOUTADEQUATE SHIMMING CAN CAUSE STRUCTURAL DAMAGE TO THE BINSIDEWALL. FAULTY CONCRETE WORK OR SHIM OMISSION WILL NULLIFY THEBIN'S WARRANTY.
7/28/2019 CB12_-_30_Degree_J-Rib_Manual_-_349001[1]
10/76
Page 9 MANUAL CHIEF42 CB12 TITAN
The suggested concrete foundation designs must not be used in conjunction with unload andaeration tunnels. Concrete and reinforcing bar requirements must be determined by a certifiedprofessional engineer. The design must consider soil bearing capacity, soil consolidation, footingrequirements, tunnel requirements and the interaction of all foundation components under loadedcondition. Non-uniform settlement of the foundation can cause severe structural damage to binand foundation. An improperly designed or constructed foundation will void all aspects of the bin
warranty. It is the responsibility of the General Contractor to insure that an adequate foundation isprovided for the bin.
5. ACCESSORY EQUIPMENT
All accessory equipment should be installed and maintained in accordance with each individualsuppliers installation and operation instructions. However, if any sidewall penetrations or othermodifications to Chief Industries, Inc., standard bin design are required, refer to bin erectionmanual or contact Chief Industries, Inc., for special recommendations. Do Not Modify Bin DesignWithout Chief Approval. It is the responsibility of the General Contractor to insure that allequipment is properly installed and that the equipment is compatible with the intended use. Aqualified electrician should be contracted to complete all electrical wiring and servicing.
Chief Industries, Inc., provides no warranty concerning parts, accessories or equipment notmanufactured by
Chief Industries, Inc.
a) Roof Peak Service Loads
When determining the service loads on the roof peak, the weight of all accessoryequipment suspendedor supported by the peak should be considered. The weights should be calculated usingthe equipment dead load plus the operating load. For example, the weight of an overheadconveyor should include the catwalk, conveyor head assembly, motors, drives,downspouts, discharges and weight of grain when in operation. If conveyor and catwalkdesign is such that snow build up is likely during winter months, snow load must be addedin the peak load calculation. If a temperature cable is suspended from peak add 1000 lbs.(452 kg.) per 40 foot (12.2 m) of cable length to the peak's service load. Interpolate valuefor intermediate cable length; i.e., 60 foot (18.3 m) cable would exert 1500 lbs. (680 kg), ofload.
b) Bin Loading EquipmentCenter filling through the peak opening is required for all bins. Off center loading willcreate unequal pressures on the bin wall and result in structural damage. If downspoutingis to be used, it is recommended that a dead head or cushion box be used to promoteuniform filling. Also, the use of spreaders or splash plates are recommended fordistributing the grain fines, promoting uniform air flow through grain and leveling the grainpeak.
IMPORTANT: FILL CONVEYORS AND THE CATWALK MUST NOT BE SUPPORTEDBY STANDARD GRAIN BIN WALL. USE INDEPENDENT SUPPORT TOWERS TOSUPPORT OVERHEAD CONVEYORS OR CB STIFFENED BINS WITH UPGRADEDSTIFFENERS TO SUPPORT THIS TYPE OF LOAD.

11/76
MANUAL CHIEF42 CB12 TITAN Page 10
c) Bin Unloading Equipment
All bins must be unloaded through center discharge. If intermediate wells areinstalled in the floor, they must not be opened until all gravity flow through thecenter well has ceased. Therefore, center and intermediate wells must haveseparate control rods. The center well's sweep auger pivot should be centered inthe bin to insure unobstructed sweep rotation. If unloading auger exits through bin wall,thoroughly seal around auger tube to prevent moisture and airflowleakage. Reinforcing of sidewall sheets will be necessary if auger exits throughthe bin wall at a point exposed to direct grain pressure. Contact Chief Industries,Inc., for reinforcing recommendations.
IMPORTANT: HIGH UNLOADING RATES CAN CREATE A VACUUM INSIDE BIN. IFUNLOADING RATES EXCEED 5000 BUSHELS (125 MT) PER HOUR, A MINIMUM OFONE FREE INTAKE VENT (GOOSE NECK VENT RECOMMENDED) MUST BEINSTALLED. ONE UNOBSTRUCTED STANDARD CALDWELL BIN VENT WILLPROVIDE ADEQUATE VENTING UP TO AN UNLOADING RATE OF 80,000 BPH (2000MT/HR). IF SUBSTANTIALLY HIGHER RATES ARE NEEDED, PLEASE CONTACTCHIEF INDUSTRIES FOR A RECOMMENDED VENT REQUIREMENT.
Sidedraw baffle systems may be installed in the bin sizes specified in Chief catalog. Also,the Chief Industries, Inc., sidedraw unit is the only approved type of sidedraw system thatcan be installed in a Chief grain bin.
IMPORTANT: ANY SIDEDRAW UNIT IMPROPERLY INSTALLED IN A CHIEF BINWITHOUT CHIEF INDUSTRIES' APPROVAL, OR SIDEDRAW UNITSMANUFACTURED BY OTHER THAN CHIEF INDUSTRIES, INC., COULD RESULT INSTRUCTURAL DAMAGE TO THE BIN AND WILL VOID THE BIN WARRANTY.
d) Temperature Cables
Temperature cables can be installed in all standard Chief bins; the number and location oftemperature cables for each bin size are listed in the temperature cable installation sectionof the erection manual.
Temperature cable support kits supplied by Chief Industries, Inc., are available and mustbe used whenever temperature cables are installed. Be sure to allow adequate clearancefor sweep augers or other internal equipment. Follow temperature cable manufacturer'srecommendations for shortening temperature cables if necessary, provide adequate
sealant where temperature cable lead wire exits the bins.
IMPORTANT: SUPPORT OF TEMPERATURE CABLES BY ANY MEANS OTHERTHAN CHIEF INDUSTRIES' RECOMMENDED SUPPORT KITS MAY CAUSESTRUCTURAL DAMAGE TO THE BIN ROOF AND WILL NULLIFY THE CHIEF GRAINBIN WARRANTY.
IMPORTANT: All TEMPERATURE CABLES SHOULD BE SECURED TO FLOOR TOPREVENT CABLE FROM DRIFTING TOWARD BIN WALL DURING FILLING. THEUSE OF LIGHT TWINE OR MONOFILAMENT LINE SECURED TO A RECESSEDANCHOR IS RECOMMENDED.

e) Fans and Transitions
Aeration fans should be sized in accordance with Chief's specifications for the particularbin being considered.
All fans must be installed per Chief's recommendations and leveled prior to operation. Aqualified electrician should be contracted to complete all electrical wiring and servicing.
The transition through the bin wall must be thoroughly sealed around the outside of thetransition entrance collar to prevent airflow leakage. Use of strip caulking in combinationwith flashing provided by the transition manufacturer is recommended. If the transitioninterrupts a stiffener line, the special transition stiffener available from Chief Industries,Inc., must be installed as described in the erection manual. Also, if the transition entersthrough the bin's bottom sidewall sheet (full floor aeration and tube aeration), adequatereinforcing of the bottom sidewall sheet must be added. Contact Chief Industries, Inc., forrecommendations. Standard drying bins do not require reinforcing of bottom sidewallsheet as long as transition enters below the false floor level.
f) Heaters
The heater unit must be properly matched with the fan size to be used. Heater unit andfan must be compatible, and it is recommended that both units be supplied by the samemanufacturer to insure compatibility and safety. Heater unit installation and servicingshould only be completed by personnel properly trained by the manufacturer of productsbeing used. The fan and heater need to be located on the bin to assure uniform airflow tothe bin. The units should be located at a position 1800 from the outlet of the withdrawaltube.
DANGER: Fuel tanks, lines and all valves must be compatible with the type of fuel to beused. Failure to use certified fuel tanks, lines or valves can result in death or severepersonal injury.
DANGER: Never use anhydrous ammonia tanks or improperly modified fuel tanks forL.P. gas storage.
DANGER: L.P. fuel flow control regulators must be installed as recommended by heaterunit manufacturer.
DANGER: Natural gas flow regulators at the service entrance must be installed by naturalgas supplier and must not be modified.
The drying temperature should be established based on the type of grain to be dried.Contact Chief for optimum drying temperature. Excessive heat can result in graindamage, overdrying and potential grain fires.
CAUTION: When drying sunflower seeds, the drying temperature should not exceed 105o Fahrenheit (410
Celcius). Higher temperatures can result in sunflower oil combustion.
g) Aeration Floors
Chief recommends the use of channellock floors with steel supports for full floorapplications. Commercial applications, (floors loaded and unloaded more than once peryear) and bins with a total grain depth of 60' (18.3 m) or greater require an 18 gauge (1.3mm) floor. The floor layout support spacing must be followed for the particular bin beingconstructed. Floor supports, fan locations and auger tube should be oriented as shown inthe manufacturer's floor plan to insure optimum airflow movement.
Corrugated perforated floors require a concrete block and lumber support system.Concrete block and lumber floor supports are not recommended in bins larger than the#13 or bins taller than eight rings. Airflow restrictions when using concrete block andlumber can significantly reduce the air flow efficiency.
7/28/2019 CB12_-_30_Degree_J-Rib_Manual_-_349001[1]
13/76
MANUAL CHIEF42 CB12 TITAN Page 12
h) Roof Ventilation
Any grain bins using forced air for aeration or drying must be provided with sufficientexhaust or intake vents to prevent excessive internal pressures, either positive ornegative. The vent supplier should be consulted for ventilation requirements on eachproject, with the specific bin size, grain type and depth, fan size and floor type taken intoconsideration. Chief Industries, Inc., does not recommend the use of negative aerationsystems. In the event that negative aeration is to be used, the intake vent requirementshould be sized for the bin in the empty condition.
IMPORTANT: ROOF VENT MUST BE FREE OF DEBRIS OR OTHER OBSTRUCTIONSPRIOR TO OPERATION OF FANS.
POWER FANS SHOULD NOT BE OPERATED WHEN AMBIENT TEMPERATURE ISBELOW 35o FAHRENHEIT (2o Celsius) DUE TO POTENTIAL OF VENT ICING.
OBSTRUCTED OR ICED VENTS CAN SIGNIFICANTLY INCREASE INTERNAL TOEXTERNAL PRESSURE DIFFERENTIAL AND COULD RESULT IN STRUCTURALDAMAGE TO BIN ROOF, WALL OR BOTH.
i) Stirring Device
Stirring devices can be installed in any drying bin, with the limitations discussed in Section3. The bins storage capacity will be reduced when installing a stirring device. Drying binstorage capacities listed in the Chief catalog should be used with the additional capacityreduction for down auger drive unit clearance. Inside ladders may require short bracketsfor wall attachment to provide clearance for the stirring device.
CAUTION: The grain level must not be filled above the stirring device. Grainpressure on the stirring device could cause roof or stirring device damage.
Down augers may require shortening in order to provide minimum floor clearance of 3"-5"(76mm -127 mm) or additional clearance for sweep augers. Manufacturers down augershortening procedure should be followed.
j) Recirculators or Continuous Flow
Recirculators can only be installed in CB bins. These devices should be installed asinstructed by the manufacturer and with the following additional considerations:
a. Consult floor manufacturer for recommended floor reinforcing measures at baseof recirculator.
b. If transfer auger exits through roof panels, provide sealant around auger tube toprevent water leakage.
c. The weight of the transfer auger must not be supported by the roof panels. Thetransfer auger should be supported by the recirculator boot and an adjacent binor independent support.

Section 2 Bin Erection
Chief Industries, Inc. will not assume any responsibility for parts damaged due to faulty or
improper erection procedures.
Chief Industries, Inc. recommends that Bin Jacks be used for all bins taller than 8 rings
and all bins larger than 30 in diameter.
WARNING:
The allowable lifting capacity of the BIN JACKS must never be exceeded. Always check Bin
weight to insure a safe and trouble free erection.
Grain Bin Color Codes
Chief Grain Bins are color coded based on bin diameter. Components such as Roof Rafters,
Wind Rings, and Base Angle will be marked with the following Color Codes to help identifythem.

B. Checking ShipmentCheck your shipment at the time of pickup and delivery against the packing list furnished
with the shipment. If a shortage exists or if any damaged material is evident, note such
shortage or damage on the freight bill before you sign for the shipment.
Claims of shortages will not be honored after thirty days from receipt of shipment.
Parts that are short or damaged are the responsibility of the delivering carrier, not the
manufacturer or dealer.
It is advisable to reorder damaged or missing parts immediately so that there will be nodelay in erecting the bin. After receiving the invoice for the reordered material, file a
claim with the delivering carrier at once.
The galvanized panels leave our plant in prime condition; store off the floor in a heatedroom if possible. If stored outside, place panels down, off the ground. Upon arrival of
shipment if you are not certain whether or not moisture is present, store panels on edge or
on end allowing 1/4 air space between panels until dry. Exposure to trapped moisture
can cause white rust, which will void the warranty.
C.Stop and Study
Before beginning erection of the bin, take the time to thoroughly study the construction
methods in this manual. It will save you both time and money .
Important:The peak load capacities listed underAuxiliary Roof Loads must not be exceeded. If your
application will exceed the listed values, contact Chief Industries for recommendations.
Chief Industries makes no warranty concerning parts, accessories or equipment not
manufactured by Chief Industries.
D. Sight Selection
Choose a site that has good drainage away from the bin so that water will not stand around
the bin. The soil should be firm and preferably without fill. If fill is required, water andcompact the fill material to avoid uneven settlement. A field investigation of the soilbearing conditions is recommended especially for larger grain bins where the foundation
loads and floor pressure become large. A licensed engineering firm should be employed to
take soil borings, determine the maximum allowable soil pressure and design the binfoundations and floor slab accordingly.

E.Bin Jack Erection
Position the structure you provided to hold the Inner Ring at its approximate height,
centering the Inner Ring on the center of the Bin.
Use at least one Bin Jack per Sidewall Sheet. (For example, on the #18 Bin, use 18 BinJacks,etc.)
The application of one bin jack per sidewall sheet will minimizesidewall distortion during
erection. Failure to use the proper quantity of jacks may result in inward-outward lay of the bin
sidewall or even permanent distortion of the bin sidewall sheets.
The recommendation of at least one Bin Jack per sidewall sheet is based on keeping the bin
round, refer to the warning below, and make sure the lifting capacity of the jack is
sufficient for the weight of the bin. Note that all jacks may not shift equally, Therefore
make sure the lifting capacity rating by the jack manufacturing is met.
WARNING:
If it is necessary to leave the construction site for any length of time before the Bin is
completed and anchored to the concrete, the Bin must be securely tied down.

Assembling top ring
Locate the proper gauge of sidewall sheets needed for the top ring from the gauge chart. Lap and
caulk sheets as shown below. Locate top stiffeners and install on top ring.
Note: Top Sheets have special punching on the top of the sheet at the stiffener holes for therafter to attach to. Leave bolts out of top (4) stiffener holes until eave brackets are
attached.
Wipe off the outside ends ofallthe Sidewall Sheets to remove excess oil so that the StripCaulking will adhere to the metal. Place the Strip Caulking as near to the vertical inside edge of
sheet at every vertical seam.
On Bins 12 gauge or heavier a horizontal strip of caulking is needed on the inside at the center
bottom of the Sidewall sheet located on the hill near to the bottom holes. This strip of caulking
should fit where the endlap of the next ring Sidewall Sheets bolts up to this location.

H. Crane and Jack Capacities
Crane Capacity:
The total roof dead load for each of the respective bin roof sizes is shown in the table below.
This weight includes the roof panels and all structural members (roof beams, compression rings,bolts, ect.)
When determining the crane capacity necessary to erect the roof structure, the booming distance
must be considered. If the cane sizes available will not lift the roof structure (using one crane),
two cranes may be used, utilizing a spreader bar. The spreader bar must be adequately designedto carry the entire roof dead weight.
CB12 Total Roof Weight = 5,100 lbs.

Roof Panel Installation
1. Install strip caulking between top end of roof panels and roof panel flashing. Use 5/16 x 3/4
bolts at top end of panel. Bolt roof panels to top angle with 5/16 x 3/4 bolts.
2. Proceed by installing additional roof panels in the following manner: Always working to theright around the bin, place strip caulking on right rib of the previously installed roof panel (top
only). Placing roof panel in a vertical position, lock the left rib of the panel being installed over
the right rib of the previously installed panel. Tip the roof panel down. As each roof panel is setinto place, insert a lining punch through the hole in the rib at the bottom of each roof panel.
Temporarily clamp the two roof panels together with vise grips so that the punch can be removed
and a 5/16 x 3/4 bolt inserted and hand tightened. Continued installation of roof panels asdescribed in preceding steps.
3. All bins are equipped with one manhole and a roof ladder as standard. Extra manholes shouldbe spaced evenly around the bin.
4. When the last roof panel is placed, it will have to be interlocked by using a rubber mallet.Starting at the top and working down, tap the vertical rib until it is sealed to the other panel.
Align roof panel holes and insert 5/16 x 3/4 bolts in the same manner as previously described.

B. Low Profile Roof Vents
1. Install the Screen and clips on the roof vent body using 5/16 x 3/4 bin bolts, nuts and flatwashers as shown below. The bolt heads should be on the outside of the vent with the
washers and nuts on the inside (against the screen).
2. Locate the roof vent assembly on the roof panel (over the manhole) by aligning the holes inthe clips with the corresponding holes in the lower end of the roof panel.
3. Mark the outline of the roof vent with a marking pencil so that the vent can be returned to thesame position after the caulking is applied.
4. Remove the vent from the roof panel, turn upside down, and apply caulking to the mounting
surface of the sides and top.
5. At this time, install and tighten three 5/16 x 3/4 bin bolts and nuts in the holes directlyabove and below the manhole (in the roof panel to prevent leakage).
6. Locate the roof vent on the roof panel in its original position and attach with the #14 x 3/4self-drilling screws provided. If a screw gun is not available, use the holes in the vent as aguide and drill 3/8 holes through the vent and roof panel, and attach with 5/16 x 3/4 bin
bolts and nuts.
7. Install 5/16 x 3/4 bin bolts and nuts in the clips and bottom of screen as shown in detail on
previous page.

Section 5 Temperature Cables
A. General ConsiderationsFollow temperature cable manufacturers recommendations for installation of temperaturecables. Be sure to allow adequate clearance for sweep augers or other internal equipment.
All temperature cables should be stabilized at floor level, to prevent cables from drifting out
towards the sidewall as bin is being filled. The use of light twine or monofilament linedouble wrapped and secured to a recessed anchor, is a common practice.
Provide adequate sealant where temperature cable leads exit the bin.
Support of temperature cables by any means other than Chief Industries recommended
brackets may cause structural damage to the bin roof and will nullify the Chief Grain Bin
Warranty.

H. Light Bin Stiffener Anchor
All bins will have ALL 2 ring bottom stiffeners. Stiffened bins may have two or three Stiffeners
per sidewall sheet depending upon bin size and height.
Bolt anchor brackets to the 2-ring bottom stiffeners and place shim plate on top of anchor
bracket. DO NOT fully tighten
After the bottom ring is attached, lower the bin carefully, placing all anchor brackets over theanchor bolts.
When full weight of the bin is on the concrete, shim the anchors as necessary by sliding shimplates between the concrete and anchor bracket. All anchors must be bearing upon the concrete
or shimmed so that full bearing of the anchor is developed.
Plastic cement or tar sealant should be applied from inside the bin to seal the bottom ring toconcrete. (NOTE: Sealant is not furnished by Chief Industries, INC.)

Bin Stiffener anchors allow up to 3 anchor bolts to be used at each anchor location. There are (2)
1 diameter and (1) 1-1/2 diameter holes in each Bin Stiffener Anchor.
There are several different combinations that Chief Industries Recommends to anchor the bin to
the foundation.
1. One 1-1/4 x 12 anchor bolt may be used in the 1-1/2 diameter hole, if this is done theanchor bolt must be pre set in the concrete
2. Two 3/4 x 12 anchor bolts may be used in the two 1 diameter holes. If this is done, at leastone of the two anchor bolts must be pre set in the concrete the second may be drilled in. (It is
recommended that both anchor bolts are pre-set.)
If anchor bolts are not pre set as stated above, and the anchor bolt radius is not held, the binswarranty may be nullified.
Larger anchor bolts or the use of all three anchor bolts may be required if seismic conditions orhigh wind loads exist. Chief Industries should be consulted for proper anchor bolts to be used.
All anchor bolts must project a minimum of 2 above the concrete floor.
All anchor bolts, nuts and washers shall conform to ASTM A307 (specification for carbon steelthreaded standard fasteners) unless otherwise noted. Anchor bolts, nuts and washers are not
provided by Chief Industries, Inc.
IMPORTANT: If expansion type anchor bolts are used to replace damaged anchor
bolts, the bolt radius circle must be checked at replacement locations so that the bin isround when anchored. Chief Industries recommends using wedge anchors that meet
10,000 LB Pull-Out and 7,500 LB shear criteria.

J. Transition Stiffeners
Aeration Trough Transition Stiffener Installations (for flush-floor aeration systems with two or
more fans)
(1)The formed concrete dimensions and the anchor bolt placement are important for the correctinstallation of the transition stiffeners. When forming the concrete, the aeration troughs
should be located as specified in Chiefs aeration layout. The anchor bolt locations for the binneed to be oriented to make sure that the number of anchors over the aeration trough is
minimized. When installing the anchor bolts, the bolt radius and bolt chord must be correct
and they must also be placed according to the details below.
IMPORTANT NOTE: Do NOT install the anchor bolts inside the aeration trench at this
time.
2 Stiffener/Sheet Bins 3 Stiffener/Sheet Bins
(2)When the bin is erected and located correctly (as illustrated above), insert the transition in theaeration trough. Using the hole in the anchor bracket as a guide, drill a 3/4 hole through the
top of the transition. Slide the transition stiffener inside the transition and line it up with thepreviously drilled hole. Loosely install the 5/8 x 1-1/2 A325 bolt. Rotate the transition
stiffener body so that it is centered under the bin wall anchor. See installation detail that
follows.
(3)The transition stiffener must be attached to the foundation with two (2) 5/8 x 6 expansion-type anchor bolts. The holes for these anchor bolts should now be located. With an acetylenetorch, cut two holes in the bottom of the transition using the holes in the transition stiffenerbase plate as guides. (This would mark the location of the anchor bolts in the concrete as
well.)
(4)Remove the transition stiffener and the transition.

Aeration Trough Transition Stiffener Installation Detail
(5)Locate the two anchor bolt locations (from cutting the holes in the bottom of the transition).Set the transition stiffener over the locations to insure that the holes line up. Also, check toinsure that the transition stiffener is directly under and in line with the anchor. Make
adjustments if necessary. Drill the two holes for the 5/8 x 6 anchor bolts.
IMPORTANT NOTE: Do NOT install anchor bolts at this time.
(6)Enlarge the two holes in the bottom of the transition to 1 diameter.
(7)Reinstall the transition and slide the transition stiffener into position Loosely install the 5/8x 1-1/2 A325 bolt and rectangular washers at the anchor bracket location. The two 5/8 x 6
expansion-type anchor bolts should now be installed and securely tightened the 5/8 bolts at
the anchor bracket. Caulking should be applied to seal the transition.
IMPORTANT NOTE: Transition stiffeners support the bin anchors. The transition must also
be supported inside the bin. See Chiefs aeration layout for supporting the transition.

K. Stiffener Upgrades for Goal Post (Optional)
When a goal post is being attached to bin, an extra layer of stiffeners are laminated over standard
stiffeners at goal post location from eave to base, as been is being erected.
Chief recommends that goal post be uniformly attached to at least the top 2 rings of tank at thestiffeners from bottom of 2
ndring to top of 1
string.
Note: Listed below are the maximum loads that can be applied to upgraded stiffener columns.

Section 8 Wind Rings
A. Wind Rings
Consult the Chief catalog for the quantity of wind rings required for your bin. The quantity ofwind rings depends on the size of the bin and the application of any accessories (such as a
sidedraw system). For quantities and placement of wind rings required when a Sidedraw System
is installed on the bin, refer to the charts in this manual. The wind rings will be attached to thesidewall using one bracket per stiffener spaced 58-5/16 apart (38-7/8 on 3 stiffened bins). The
brackets are specially formed and prepunched to bolt directly to the sidewall stiffener holes. The
wind ring segments will be joined together using a bolted coupler.
NOTE: All wind ring segments are 248 long, and may need field cut to keep couplers in
between brackets. Always cut segments on end opposite end with pre-punched hole.
(1)Working from outside the bin, determine the proper location for installation of the first windring.
(2)Bolt the first wind ring bracket to the sidewall stiffener holes as shown in Detail below using(2) of the stiffener attachment bolts and nuts with bolt heads on the inside. (Note: Wind ring
brackets may be installed below the endcaps if desired to allow for clearance of ladders andplatforms.)
