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/m 3) free flowinggrain (52.5 PCF (841 kg/m 3) 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/m 3 ),products having unusual flow characteristics or unusual corrosive properties) must beap pr ov ed by Ch ie f In du st ri es ' Engineering Department prior to quoting. Storage of soybean meal or meat 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/m 2) 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 or more 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.


10/83


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 binwarranty. It is the responsibility of the General Contractor to insure that an adequate foundation is

provided 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 other modifications 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 byChief 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), of load.

b) Bin Loading Equipment Center 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 for distributing 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.


11/83


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 of temperature 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 adequatesealant 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.


12/83


e) Fans and Transitions

Aeration fans should be sized in accordance with Chief's specifications for the particular bin 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., for recommendations. 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 180 0 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 for L.P. gas storage.

DANGER: L.P. fuel flow control regulators must be installed as recommended by heater unit 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 105 o Fahrenheit (41 0Celcius). Higher temperatures can result in sunflower oil combustion.

g) Aeration Floors

Chief recommends the use of channellock floors with steel supports for full floor applications. Commercial applications, (floors loaded and unloaded more than once per year) 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.


13/83


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 or negative. 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 35 o FAHRENHEIT (2 o 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 auger shortening 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.


14/83


Section 2 Bin Erection

Chief Industries, Inc. will not assume any responsibility for parts damaged due to faulty orimproper erection procedures.

Chief Industries, Inc. recommends that Bin Jacks be used for all bins taller than 8 ringsand all bins larger than 30 in diameter.

WARNING:The allowable lifting capacity of the BIN JACKS must never be exceeded. Always check Binweight 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 Shipment

Check your shipment at the time of pickup and delivery against the packing list furnishedwith the shipment. If a shortage exists or if any damaged material is evident, note suchshortage 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 themanufacturer 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 aclaim 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 moisturecan 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 constructionmethods in this manual. It will save you both time and money .

Important: The peak load capacities listed under Auxiliary 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 notmanufactured 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 soil

bearing conditions is recommended especially for larger grain bins where the foundationloads and floor pressure become large. A licensed engineering firm should be employed totake soil borings, determine the maximum allowable soil pressure and design the binfoundations and floor slab accordingly.


16/83


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 minimize sidewall distortion duringerection. Failure to use the proper quantity of jacks may result in inward-outward lay of the binsidewall 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 binround, refer to the warning below, and make sure the lifting capacity of the jack issufficient for the weight of the bin. Note that all jacks may not shift equally, Thereforemake sure the lifting capacity rating by the jack manufacturing is met.


17/83


F. Assembling Sidewall Sheets

All bolts are washer head bolts with sealing washers S.A.E. Grade 8, with whiz flangenuts. Grade 8 bolts are marked with six radial lines on the bolt head as shown. If these

descriptions do not correspond with the bolts shipped with the bin, please contact thecustomer service department immediately. Do not substitute any other Bolts.

Bin bolts must be TIGHT . The following table contains recommended minimum andmaximum torque values.

BOLT DIA. TORQUE FT. LBS(INCHES) MINIMUM MAXIMUM

5/16" 22 287/16" 60 75

Tighten the bin bolts from the inside of the bin (nut end of the bolt) to eliminate spinoff of the sealing washer.

USE ONLY THOSE BOLTS SUPPLIED BY CHIEF INDUSTRIES.THE SUBSTITUTION OF BOLTS FROM OTHER SOURCES IS NOT PERMITTED.

The top 2 rings of the bin and the roof should be assembled on the concrete bin floor.Attach the lifting brackets to the bolts at the endlaps of the sidewall sheets. The lifting

brackets must be attached to the endlap by at least 8 standard bin bolts.

NOTE: Proper bolting sequence MUST be followed at all times.


18/83


The Titan Sign Sheet must be installed in the second ring as shown in figures below.

(Shown installed on a 2 stiffened bin)

(Shown installed on a 3 stiffened bin)

Install the Titan Sign Sheet by field drilling (6) six holes in the Titan Sign Sheet andstiffeners as shown above. Bolt the Titan Sign Sheet to the stiffeners with (6) six 7/16 bolts.


19/83


Assembling top ring

Locate the proper gauge of sidewall sheets needed for the top ring from the gauge chart. Lap andcaulk 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 areattached.

Wipe off the outside ends of all the 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 caulkingshould fit where the endlap of the next ring Sidewall Sheets bolts up to this location.


20/83


G. Roof Panel Location

The rafters need to be bolted directly behind a top 2 ring stiffener, the roof panel rib will line updirectly above the rafter from the peak to the eave. (There is 1 Rafter and 4 roof panels per sidewall sheet.)


21/83


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 distancemust 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.

Peak Heights

All peak heights listed below are to the bottom of the peak ring from the ground with (2) Titansidewall sheet rings installed. Deduct 42 1/2 from the peak heights when only one ring of sidewall sheets are installed.

Section 5 Temperature Cables

A. General Considerations

Follow 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 outtowards 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.

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 tothe 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 isrecommended 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 or high 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 meet10,000 LB Pull-Out and 7,500 LB shear criteria.

F. 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 troughsshould 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 isminimized. When installing the anchor bolts, the bolt radius and bolt chord must be correctand they must also be placed according to the details below.

IMPORTANT NOTE: Do NOT install the anchor bolts inside the aeration trench at thistime.

(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 thetop of the transition. Slide the transition stiffener inside the transition and line it up with the

previously drilled hole. Loosely install the 5/8 x 1-1/2 A325 bolt. Rotate the transitionstiffener body so that it is centered under the bin wall anchor. See installation detail thatfollows.

(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 stiffener

base plate as guides. (This would mark the location of the anchor bolts in the concrete aswell.)

(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. Makeadjustments 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 6expansion-type anchor bolts should now be installed and securely tightened the 5/8 bolts atthe 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.

G. Stiffener Upgrades for Goal Post (Optional)

When a goal post is being attached to bin, an extra layer of stiffeners are laminated over standardstiffeners 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 nd ring to top of 1 st ring.

Note: Listed below are the maximum loads that can be applied to upgraded stiffener columns.16GA stiffener upgrade = 5,000 lbs. per column14GA stiffener upgrade = 6,000 lbs. per column

Section 8 Wind Rings

A. Wind Rings

Consult the Chief catalog for the quantity of wind rings required for your bin. The quantity of wind rings depends on the size of the bin and the application of any accessories (such as asidedraw system). For quantities and placement of wind rings required when a Sidedraw Systemis 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. Thewind 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 and platforms.)

ASSEMBLYDETAIL OFWIND RINGBRACKET

(3) Move right to the next stiffener and repeat step 2.

(4) When 4 wind ring brackets have been installed, slide the first ring segment through the four brackets leaving approximately 29 inches of the segment projection past the last bracket.Insert coupler over end of wind ring segment, and attach with 5/8 x 4 bolt.

(5) Repeat step 2 through 3 until four more brackets have been installed.

(6) Slide another connector into the end of the previously installed ring segment. Slide the nextring segment through the four brackets and butt it firmly against the previous segment.

(7) Repeat steps 5 and 6 until only one ring segment remains to be installed. Installing thefinal ring segment requires special procedures.

(8) Attach coupler to end of last wind ring segment.


77/83


(9) Slide coupler attach to segment over end of 1 st segment so segments are bolted together.

(10) Field cut other end of segment so segments are flush.

(11) Slide last coupler and brackets over segments.

(12) Hold segments flush and slide coupler over joint and attach with 5/8 x 4 bolts. Attach brackets to stiffeners

(15) Check to see that all bolts in the complete wind ring are tight

(16) Repeat steps 1 through 13 for the remaining wind rings.
