IMPORTANT NOTES

1. In order to maintain your wall sheets in good condition separate sheets and allow air circulation between them. Store sheets in a dry place. Do not store sheets with sheet ends pointing upwards.

2. To keep an even pressure on walls, the bin must always be unloaded from the centre. 3. Contact local power officials for minimum power line clearance. 4. See "Disclaimers - Design" for materials which can be stored. 5. Tighten all bolts to the recommended torque setting (see Recommended Bolt Torques

table in Appendix). 6. Do not locate grain bin close to high buildings, which might cause snow to fall onto or

build up on the roof of the grain bin. Consider future expansion and allow space for loading and unloading of the bin. Your dealer and local government agricultural consultants can help you plan your storage system for maximum efficiency.

Shortages and Damaged Parts; Report damaged parts or shortages immediately to the delivering carrier, followed by a confirming letter requesting inspection by the carrier, if required. Order any replacement parts immediately to ensure that assembly will not be held up by missing parts. All parts will be charged for and credit will be issued by party at fault - no credit will be issued if freight bill are signed as received in good condition.

Order Optional Equipment; Optional equipment such as unloading augers, aeration equipment, anchor bolts, foundation sealant, external ladders, safety cage and platforms, etc., should all be on site and checked before assembly starts. Plan your installation in advance. For details, see assembly instructions supplied with optional equipment.

3. Before You Begin3.1. Bin Design and CapacityStandard Twister Grain Bins are designed for:

1. Non-corrosive free-flowing materials up to 55 lbs/ft3 (880 kg/m3) average compacted bulk density.

2. Maximum horizontal gusted wind speed of 94 mph (151 km/h)

3. Zero seismic activity

NoteSeismic resistance in grain bins varies with height and diameter. Many standard designs havesignificant seismic capabilities. Designs can be reviewed and/or modified to reflect local seismicrequirements.

4. Roof loading capabilities vary with diameter, peak load and snow load.

a. Peak Loads – standard peak loads follow. Upgrades are available.

Table 1. Peak Loads for Various RoofsSize Type of Roof Load (lbs) Load (kg)

18’ - 24’ non-structural 4000 lbs 1814 kg

b. Roof Snow Loads (RSL) – at the above stated standard peak loads, standard RSLs vary with diameter andrange from 16 psf (78 kg/m2) to 45 psf (219.7 kg/m2). Upgrades are available.

NoteThe correlation between ground snow load (GSL) and roof snow load (RSL) for grain bin designsvary with jurisdictions. In the US GSL = 2 x RSL. In Europe GSL = 1.25 x RSL. In Canada thecorrelation between GSL and RSL varies and is site specific.

c. For maximum roof snow load capacities for various sizes and types of roofs, refer to the Roof DesignCapacities sections that follow.

Note

1. Standard roofs are adequate for many applications but additional capacity is available when optional upgrade packages are used.

2. Upgrade packages include roof stiffening rings and/or rib supports.

3. For peak load between standard and upgrade limits, a straight line interpolation can be used to determine maximum roof snow load.

4. Higher level upgrade kits include all components from lower level kit; only one upgrade kit needs to be ordered for any given bin.

3.1.2 Roof Snow Load vs. Ground Snow LoadThe Roof Design Capacity tables reflect roof snow load (RSL) values. These are design values. Often,comparisons are made to ground snow values (GSL). These are not the same. The conversion from GSL to RSLvaries between jurisdictions and is governed by building codes:

• In the United States, for grain bins, GSL = RSL x 2

• In Europe, for grain bins, GSL = RSL x 1.25

• In Canada, for grain bins, the GSL/RSL conversion varies with every location across the country. However, forcomparison purposes, the US conversion can be used as an approximation.

Therefore, when comparing against competitive GSL values in the US, double the above values. Whencomparing against competitive GSL values in Canada, double the above values for a reasonably closeapproximation.

3.2. Guidelines for Supporting Catwalks and other External Loadson TwisterFrequently catwalk and related equipment loads are supported on grain bins. Such connections are commonlymade into the grain bin stiffeners and across the peak. A grain bin is a thin shell structure primarily designed towithstand the internal uniformly distributed loads inherent with the stored bulk material inside of the bin.Special considerations must be given to the manner in which external loads are supported. Twister hasdeveloped products which are compatible with these requirements and considerations. If a third party solutionis provided, the provider assumes full responsibility of the structure, its load distribution, and the manner inwhich it is connected to the grain bin. The following guidelines must form part of the third party designconsiderations.

3. BEFORE YOU BEGIN FARM SERIES GRAIN BIN–ON HOPPERS(TWISTER DOMESTIC) – WIDE-CORR® GRAIN BIN

198863 R3 11

Connection to Stiffeners1. The available catwalk support stiffeners in Twister stiffened bins are for 10,000 lb incremental catwalk loads

and 20,000 lb incremental catwalk loads per upgraded stiffener. The actual loads subjected to a singlestiffener by the mating catwalk support shall not exceed these maximum capacities.

2. Twister recommends that the vertical load transfer between the catwalk supports and the stiffener occurover a minimum distance of 66” for 10,000 lb loads and 120” for 20,000 lb loads. Adequate connectionstrength must be provided.

3. The catwalk support stiffener in Twister bins are designed to provide vertical load support only. Any lateralloads subjected to the grain bin must be negligible.

4. There is a restriction of 2 upgraded catwalk support stiffeners per bin location. Therefore, the maximumsupported load at the grain bin eave is 20,000 lbs (for two 10,000 lb upgrades) and 40,000 lbs (for two20,000 lb upgrades). This can be repeated on the opposing side of the bin at a second location. Deviationfrom this must be approved by Twister Engineering.

Connection to Peak Rings1. The allowable vertical peak load to any Twister bin roof is restricted to its published rated capacity. The load

must be centered and evenly distributed into the peak ring. Any off-centre load and/or improper loaddistribution may cause roof failure.

2. A Twister structural roof requires the peak support loads to be transferred directly into the compressionring/roof rafter system. This is accomplished with peak load support brackets that are included with thestructural roof. They must be installed as shown in the structural roof manual, connecting the peak supportstructure to the compression ring. They are required even if a non-Twister peak support structure is used. Anon-Twister peak support structure needs to be designed to be able to connect with the brackets. Therequired bolt pattern is shown in the structured roof manual.

3. A Twister non-structural roof that is supporting a catwalk requires six clips to be installed in order to attachthe flat cap to the peak ring. These clips are available from Twister.

3.3. Foundation Design and LoadsThe foundations for the stiffened bin models are based on 4000 lbs. per sq. ft. (192 kPa) soil bearing capacity.All foundation designs use 3000 lbs. per sq. in. (21 MPa) ultimate compressive strength (after 28 days) forconcrete and 43,500 lbs. per sq. in. (300 MPa) re-bar. The foundation designs included in this manual aresuggestions only, and will vary according to local soil conditions. Twister will not assume any liability for resultsarising from their use.

ImportantFoundation should be uniform and level. Level should not vary by more than ¼" over a span of four feetunder the bottom ring angle. Any variance from level must be shimmed under upright base assembly. Ifbeing utilized to support a full floor aeration system, this levelness requirement should extend acrossthe complete floor area.

3.4. Site and AssemblyUnless otherwise specifically provided in writing, Twister does not take responsibility for any defects or damagesto any property, or injury to any persons, arising from or related to any site or assembly considerations,including but not limited to:

• Bin location and bin siting


12 198863 R3

• Soil conditions and corresponding foundation requirements (note that the examples provided in manualsare for specifically stated soil conditions)

• Bin assembly (Twister recommends the use of qualified bin installers; contact Twister for information oninstallers in your area)

• Field modifications or equipment additions that affect the bin structure

• Interconnections with neighboring structures

• Compliance with all applicable safety standards, including but not limited to fall restraint systems (ladders orother systems). Local safety authorities should be contacted as standards vary between jurisdictions.

3.5. Methods of InstallationThe recommendations for assembling and installing Twister grain bins must be closely followed to achieve thefull strength of the bin and to achieve adequate weather sealing. The product warranty is void if:

1. Wall sheets and/or uprights not specified for a given tier are used.

2. Foundations are found to be inadequate or out-of-level.

3. Anchor bolts (cast-in-place, drill-in, chemical type or other) are found to be inadequate.

4. Off-center loading or unloading is used. (This does not apply to the use of approved side unloading systems.)

5. Materials stored are not free-flowing or have a compacted bulk density greater than 55 lbs/ft3 (880 kg/m3).

If using bin jacks during assembly, always lift on an upright. Choose a hoist with a adequate capacity for theexpected empty bin deadload. Make sure the rated capacity of the hoist is not exceeded.

3.6. Cutting Openings in Wide-Corr® Grain BinsThis section provides instructions for cutting openings to accommodate fan transitions, unloading augers androof vents.

General Rules for Cutting openings1. Never cut any uprights, roof ribs, or wall sheet bolted vertical seams to create an opening.

2. Openings shall be located so equipment being installed won't interfere with any bin components/accessories.

3. Openings shall be minimized as much as possible for structural integrity of grain bins.

4. Corners in openings shall be cut with minimum radius of 1/8" to reduce stress concentration.

5. Openings shall be sealed all the way around for all weather conditions.

6. Instructions shall be followed closely to avoid damage to bin structure.

7. Except cutting openings described below, any other modification to Twister bins shall be approved by aprofessional engineer.

Openings for Fan Transitions of Aeration Floors1. Consult aeration floor installation instructions for information on Planning floor layout.

2. Openings shall be centered to a wall sheet in horizontal direction.


198863 R3 13

3. Opening shall be cut as tight as it can be for the transition to go through and shall have no more than 1/4"gap on any side to the section of a fan transition going through a bin wall.

4. Opening height for fan transition shall be limited to 12.5" inches from bottom edge of a bottom wall sheet.

5. Opening width shall not exceed 46.5" for stiffened bins and 72.5" for unstiffened bins.

6. Vertical support shall be required to support load above opening.

7. Bottom angles may be cut flush to the sides of an opening to form part of opening.

Openings for Unloading Augers of Wide-Corr® Bins with Full Floor Aeration1. Consult aeration floor installation instructions for information on Planning floor layout.

2. Openings shall be centered to a wall sheet in horizontal direction.

3. Openings shall be cut as tight as it can be for unloading auger to go through and shall have no more than 1/4" gap to auger flange section on any side.

4. Opening height for any auger shall be limited to 12.5" from the bottom edge of a bottom wall sheet.

5. Vertical flange of a bottom angle may be cut flush to sides of an opening to form part of opening.

Openings for Roof Vents in Roof Sheets1. Openings shall be centered between roof ribs and have 2.5" minimum distance between edge of opening

and base of a roof rib.

2. Openings can be square, rectangular, or round.

3. Openings shall be the same size as the inlet opening of a vent being installed.

4. Any side of a square/rectangular opening shall have a maximum length of 18" and a circular opening shallhave a maximum diameter of 24".

3.7. Critical Assembly RequirementsTo ensure a successful, safe and reliable outcome you must comply with the following assembly techniques andpractices:

1. Comply with all local code and jurisdictional requirements applicable to your grain bin installation.

2. Design and build foundations with the necessary strength for the loads they must support, and for local soilconditions. Twister foundation guidelines are based on specific stated conditions and may not be applicableto local conditions.

3. Your foundation must provide uniform and level support to the structure being supported. Surfaceimperfections causing gapping must be remedied. This may involve, but not be limited to a) grouting underthe bottom ring of a non-stiffened bin or tank, and b) shimming under the uprights of a stiffened bin ortank, or under the legs of a hopper.

4. Make sure that the proper hardware is utilized for all bolted connections. If a shortage occurs, do notsubstitute. Take the necessary steps to obtain the proper hardware. Make sure nuts are tightened to therequired torque values as specified in the appropriate assembly manual.

5. Comply with all assembly instructions provided in the appropriate assembly manual to make sure yourwhole grain bin is constructed safely. Important: Do not deviate from the wall sheet and upright layoutsprovided.


14 198863 R3

6. Before anchoring your structure to its foundation, make sure the structure is round. The maximum variationfrom perfect roundness is 3/4" on the radius. Locate anchor bolts toward the outside of the anchor boltholes (away from the circle) to permit the incremental expansion that can occur with the initial filling.

7. When installing roof stiffening rings, if it is necessary to shorten the stiffening ring tubes, shorten them aslittle as possible. Initially the nuts on the expanders should be centered and as close together as possible.When tightening, share the amount of take-up between expanders such that the nuts remain centered, andthe amount of engagement between all expanders on the same ring is equalized.

8. If extending an existing bin or tank, ensure that the foundation is adequate for the increased loads it mustsupport.

9. If installing an existing bin on a hopper, make sure the bin is designed for a hopper application, and that thefoundation is capable of withstanding the substantial point loads that the hopper legs apply. If uprights arepresent, make sure that they are supported.

10. Make sure that an integral end-to-end connection exists between all mating uprights. Successive uprightsmust not overlap.

11. Vertical tolerances between uprights and wall sheets are tight. This can be affected by “jacking” techniques,which can allow the tolerance to grow or shrink depending on the technique used. The gapping betweensuccessive uprights must be monitored to ensure that upright holes align with wall sheet holes.

12. If catwalks are being installed on the structure, upright catwalk upgrades are likely required. The upgradedstiffeners must be installed in the correct locations to support the intended catwalk loads. Also, thestructure must be properly oriented to ensure the eventual correct alignment between the catwalks and thesupporting uprights. Finally, the connectors that tie into the uprights and support the catwalks are bestinstalled during assembly of the structure. See the catwalk assembly manual for additional details.

3.8. Product Storage

Rust on Galvanized Parts1. White rust forms when moisture is allowed to collect on galvanized surfaces that have yet to develop the

durable zinc oxide layer. This zinc oxide layer naturally occurs as the surface interacts with carbon dioxide,and is characterized over time by the dull grey appearance that weathered galvanized surfaces get.

2. Parts that are not well ventilated or well drained can collect water between surfaces and develop white rust.

3. White rust is not a structural concern if its development is stopped in the early stages. A light film orpowdery residue can occur after a period of heavy rainfall or a short time of improper storage. If white rusthas started to develop, separate parts and wipe off any moisture. Next, using a clean cloth, apply a thinlayer of petroleum jelly or food-grade oil to the entire part.

4. If moisture is left on parts, this white rust can become more aggressive and turn into red rust. Red rust cancause degradation in the material and become a structural concern. Any parts that have red rust should bereplaced immediately.

Storage Guidelines• Keep all bundles dry before assembly of the bin.

• Start assembly as soon as possible.

• Do not lay bundles on the bare ground. Raise all bundles 6" to 8" off the ground on wood blocks or timbers.(See Detail A in Figure 2 on page 15.)

• Store curved wall sheets ‘hump-up’. (See Detail A in Figure 2 on page 15.)


198863 R3 15

• All other bundles material should be placed so that they are well sloped to promote good drainage. (SeeDetail B in Figure 2 on page 15.)

• Roof sheets must be elevated at least 12" at the small end of the sheets. (See Detail B in Figure 2 on page15.)

• Temporary storage can be provided by erecting a simple framework supporting a waterproof tarp. (SeeDetail C in Figure 2 on page 15.)

• All bin boxes, ladder boxes and hardware boxes should be stored inside. These are not waterproof, and willdeteriorate in normal weather conditions, allowing moisture to contact the parts inside.

3. White rust is not a structural concern if its development is stopped in the early stages. A light film or powdery residue can occur after a period of heavy rainfall or a short time of improper storage. If white rust has started to develop, separate parts and wipe off any moisture. Next, using a clean cloth, apply a thin layer of petroleum jelly or food-grade oil to the entire part.

4. If moisture is left on parts, this white rust can become more aggressive and turn into red rust. Red rust can cause degradation in the material and become a structural concern. Any parts that have red rust should be replaced immediately.

Storage Guidelines

1. Keep all bundles dry before assembly of the bin. Start assembly as soon as possible. Do not lay bundles on the bare ground, raise all bundles 6” – 8” off the ground on wood blocks or timbers. Store curved wall sheets ‘hump-up’. All other bundles material should be placed so that they are well sloped to promote good drainage.

2. Roof sheets must be elevated at least 12” at the small end of the sheets.

3. Temporary storage can be provided by erecting a simple framework supporting a waterproof tarp.

4. All bin boxes, ladder boxes and hardware boxes should be stored inside. These are not waterproof, and will deteriorate in normal weather conditions, allowing moisture to contact the parts inside.

If Parts Become Wet

1. If goods become submerged or wet, the bundles should be opened as soon as possible, sheets or material separated and dried. Keep separated until assembly. Brace goods properly so as to avoid damage or injury from material falling when in storage.

2. Any boxed goods that become wet should be dried and stored in a new box that is free of moisture.

3. In addition to wiping down wallsheets, a food-grade oil can also be applied with a clean, lint-free cloth. This will assist in preventing any further moisture from contacting the galvanizing on the steel. Due to safety concerns with installation and use, Westeel does not recommend the use of oil on other parts such as roof sheets and safety ladders.

3.9. Grain Bin Use• Do not off-center unload a grain bin. It is imperative to unload from the center of the bin first, until as much

grain as possible has been removed, and only then proceed to unload from the next closest unload gate tothe center. Continue utilizing the unload gates in succession from the center towards the outside. Gatecontrol mechanisms should be clearly marked and interconnected to prevent an external gate from beingopened first.

• The only exception to center unloading is when a properly designed and installed side draw system isutilized. However, as bins tend to go out of round when employing side draws, the bin must be completelyemptied before refilling.

• When unloading a bin with a mobile auger through a properly designed auger chute, the entry end of theauger should be pushed into the center of the bin before the auger is engaged. Slower rates of flow arepreferable and should not exceed the capacity of an 8” auger.

• Ensure that the inner door panels of grain bin doors are completely closed and latched before filling thegrain bin.

• Never enter a loaded grain bin for any reason. Grain can be a killer.

5. AssemblyBefore continuing, ensure you have completely read and understood this manual’sSafety section, in addition to the safety information in the section(s) below.

5.1. Assembly Safety

• Do not take chances with safety. The components can be large, heavy, and hard to handle.Always use the proper tools, rated lifting equipment, and lifting points for the job.

• Carry out assembly in a large open area with a level surface.

• Always have two or more people assembling the grain bin.

• Make sure you have sufficient lighting for the work area.

• Tighten all fasteners according to their specifications. Do not replace or substitute bolts,nuts, or other hardware that is of lesser quality than the hardware supplied by themanufacturer.

• Stay away from overhead power lines and other obstructions during assembly. Contact withpower lines can cause electrocution.

• Do not work in high winds.

5.2. Typical Non-Structural Roof InstallationThe following is a step-by-step procedure for assembling a non-structural roof system.

5.2.1 Prepare to Install the Roof1. Inspect the concrete foundation to insure that the foundation meets all the requirements of the installation.

2. Plan the assembly:

a. Determine the desired bin orientation.

b. Determine the locations of bin features and accessories (Twister logo, fall restraint brackets, GrainGauge, unloading devices, outside ladder, spiral stairs).

These considerations affect the location of the inspection hatch roof panel and the placement of the roofladder or roof stairs.

3. Prepare the peak ring:

a. Install the supplied bulb gasket around the top of the peak ring.

b. Install the foam closure gasket around the center section of the peak ring.

Refer to Figure 3 on page 19.

Step #3: Add the supplied bulb gasketaround the top of the peak ring andfoam-closure-gasket around the center section as shown (Detail 1).

Step #4: A tier of wall sheets (or possiblyto support the roof. Start assemblingUsage” section in this manual forWhen one tier is complete attach thewall sheets. Do not allow a joint between two adjacent top-ring-angles to be positioned directly over the Grain-gauge cutout in one of the top wall sheets. Ensure that the joint between top-ring -angle sections is at least 2 or 3 wall sheet holes away from the Grain-gauge cutout. Follow guidelines concerningtank roundness tolerances as laid outon the Bin Roundness page in thismanual.

Step #5: Suspend the peak-ring assembly to the top of the center post. Refer to the "bin-roundness-table" for correct heights and peak-ring sizes (Detail 2).

Step #6: Begin laying out roof-panels by attachingthe narrow end to the peak-ring and the wide end to the top of the top-ring-angle. It is recommended that you first attach four roof-panels at the quarter points of the bin; this willstabilize and support the peak-ring for the rest ofthe install (Detail 3). Ensure that the gap between the roof-panel and the peak-ring issealed by foam closure. (Detail 1). Note that the center hole in the roof panels aligns with roundholes in the top ring angle.

TIP: The narrow end of the roof panels gets pushed into the foam closure. Once this occurs there is

little room for adjustment at the top end as the roof panel is embedded in the foam. Sometimes the roof panels get “flattened” slightly from bundling, shipping and handling. It is relatively easy to push the ribs together slightly but this should occur before the panel is seated in the foam. Monitor the alignment of mating roof panels with the underlying holes in the peak ring and make adjustments, if necessary, before anchoring the roof panel into the foam.

IMPORTANT: Avoid shortages. Consult “Hardware Usage” table for proper hardwareusage for all bin connections.

Page C2

4. Install the center post making sure the post is vertical, braced and anchored properly for safe installation.

5. Lay out the bin circumference (for the bottom tier of wall sheets) on the foundation:

a. Anchor a string to the exact center of the concrete foundation.

b. Determine the required string length using the Scribe Radius and Peak Ring Height table at the end ofthis section.

NoteThe radius ’values given in the chart are 3/4” smaller than the wall sheet radius at the bottom.This ensures that the scribed circle can be seen during assembly. A perfectly placed ring ofsheets should be 3/4”on the outside of this scribed circle.

c. Scribe the bin circumference onto the foundation.

ImportantFollow these steps carefully. It is imperative that the bin be as round as possible.

3. Refer to the Appendix for information on proper hardware usage.

4. After the first ring of wall sheets has been assembled, check the position and roundness of the ring:

a. Verify that the bin is round, with no more than 0.75" variation on the radius, when measured from thecenter of the bin.

b. Verify that the wall sheets form a smooth circle with no flat spots or cauliflower shaped curves.

NoteCorrecting for roundness becomes much more difficult the longer you wait.

5. When setting jacks, make sure they are also set round and that they are anchored to the concrete.

6. Attach the top ring angle to the inside top of the wall sheets.

• Do not align the top ring angle joints with wall sheet joints.

• Make sure that top ring angle joints are at least two or three wall sheet holes away from the GrainGauge cutout.

• If building a stiffened bin, do not install the top angle bolt that lines up with the stiffener holes at thistime. It needs to be installed with the stiffeners.

5.2.3 Install the Peak Ring1. Determine the correct peak ring height (H) for the bin size from the Scribe Radius and Peak Ring Height

table in Section 5.2.1 – Prepare to Install the Roof on page 18.

2. Attach the peak ring assembly to the top of the center post at the correct height for the bin beingassembled.

TipThe narrow end of the roof panels gets pushed into the foam closure. Once this occurs there is littleroom for adjustment at the top end as the roof panel is embedded in the foam. Sometimes the roofpanels get “flattened” slightly from bundling, shipping and handling. It is relatively easy to push therigs together slightly but this should occur before the panel is seated in the foam. Monitor thealignment of mating roof panels with the underlying holes in the peak ring and make adjustments, ifnecessary, before anchoring the roof panel into the foam.

ImportantBe careful when attaching the bottom of the roof panels to the top ring angle. The center roundholes at the bottom of the roof panels must align with round holes in the top ring angle. This locksin the correct centering location for the roof sheet. The other holes in the bottom of the roof sheetalign with the round holes in the top ring angle.

3. Make sure that the gap between the roof panel and the peak-ring is sealed by the foam closure.

4. Make sure the center hole in the roof panels aligns with round holes in the top ring angle.

5. Install the remaining roof panels, working in a counter clockwise direction:

a. Attach the center roof panel hole first.

b. Use two bolts at each roof panel to peak ring connection.

c. Fill in every bolt hole in roof panel ribs with rubber washered bolts to the outside and nuts on theunderside.

d. Make sure the left roof rib overlaps the right rib of the preceding panel. (See Detail 2 in Figure 6 on page22.)

ImportantAs assembly proceeds, additional support is advised to keep the peak ring level. Alternativelysequentially add roof panels in the different quadrants such that the weight of the panels on thepeak ring remains uniformly distributed. Leave all roof bolts loose until the roof is completelyassembled, especially those at the peak ring and top ring angle locations.

e. If the number and diameter of optional roof stiffening rings is known, install the roof ring brackets (witha neoprene gasket under each) in the double rib hole locations as you add roof panels. (See Detail 1Figure 6 on page 22.)

6. Install vent roof panels where required, as the roof is being assembled.

Distribute vent roof panels evenly around the roof. Ensure that they do not interfere with other roofelements such as roof stairs or rungs, temperature cables, etc.

NoteTwister supplied roof vents come in two styles: Gooseneck and Round. Both have pre-formed boltholes for mounting to the roof panel. The vent roof panels have a raised mount section, mountingholes and a pre-cut ventilation opening. No on-site cutting is required. A recommended practice isto assemble the vents to the roof panels at ground level before installing. Place a strip of caulking allthe way around the weather side of the connection, position the vent, and bolt into place.

Figure 7. Roof Vent Assembly

Step #7: Begin filling in the remaining roof-panels, in a counter-clockwise direction, with the left roof rib overlapping the right rib of proceeding panel (Detail 5). Attach center roof panel hole first, as described above. Use 2 bolts at each roof panel to peak-ring connection. Fill in every bolt hole in roof-panel ribs with rubber washered bolts to the outside and nuts on the underside. If number and diameter of optional roof stiffening rings is known, install the roof-ring-brackets (with a neoprene gasket under each) in the double rib hole locations as you add roof-panels. (Detail 4)

Remember to install vent roof panels where required and as the roof is being assembled. Theyshould be evenly distributed around the roof such that they do not interfere with other roofelements such as roof stairs or rungs, temperature cables, etc. Westeel supplied roof vents come in two styles…Gooseneck and Round.

The inspection hatch can be pre-assembled if desired. (See Section 5.7. – Inspection Hatch Details (15’ – 54’)on page 35.)


198863 R3 23

8. Install the roof ladder on the roof sheet to the left of the inspection hatch. (See Section 5.3. – Roof LadderDetails on page 28.)

Enough roof ladder rungs are supplied to bridge across every pair of holes on a single roof panel. Whereroof stiffening ring brackets are placed, the ladder rung can be skipped. The roof ring will serve as a rung inthis location. Roof ladder rungs are installed with the higher vertical flange facing the peak ring.

5.2.5 Install Roof Stiffening Rings1. Add roof stiffening rings (if required):

a. For standard roof stiffening ring locations see Section 5.2.6 – Roof Reinforcing Matrix on page 26.

b. On roofs with multiple stiffening rings, stagger the ring joints to avoid having more than one joint onsame roof sheet. (See Figure 8 on page 23.)

Step #8: Remember to install inspection-hatch roof panel where required. The inspection-hatch can be pre-assembled if desired. (See installation of "Inspection Hatch" detail page) Installthe roof ladder on the adjacent roof sheet. (see "Roof Ladder and Sheet" detail page). Enough roof-ladder-rungs are supplied to bridge across every pair of holes on a single roof-panel. Where roof stiffening-ring-brackets are placed, the ladder-rung can be skipped. The roof-ring will serve as a rung in this location. Roof-ladder-rungs are installed with the highervertical flange facing the peak-ring.

Step #9: Add roof-rings (if required). See“Roof Reinforcing Matrix” table belowfor standard locations. Roof Rings are joined together by inserting a Ring Splice into the facing ends and pushing everything together tightly. Secure the splice to the roof ring with a self drilling screw (see Detail 8). The final connection uses a Ring Expander inserted between the final ring sections, and threading the expansion bolts until everything istight. Slide stiffening ring tubes intobrackets as required. Use an expander to make the last connection. On rings with multiple expanders, the expanders should be evenly spaced around the roof.On roofs with multiple stiffening rings, stagger the ring joints to avoid having more than one joint on same roof sheet. (Detail 7)

The last stiffening ring segmentmust be field cut such that there is a 2½" gap between the matingtubes. With nuts close to one end, insert long end of Ring Expander into one tube and, by flexing both tubes, make the connection to the mating tube. Then thread both nuts towards the center. The green paint on the threaded portionindicates the center (Detail 9)

Install the remaining stiffeningring clips. Tighten roof hardware. (see ‘Recommended Bolt Torque Table’) Expand nuts on stiffeningring expanders until slack has been taken up and roof is snug. Do not overtighten and crown the roof. Nuts must be centered on the threaded rod. Use the painted marking as a guide. On rings with multiple expanders, the distance between the nuts on all of themshould be equal. (Detail 9)

5.2.9 Install Associated Components1. Assemble bin entry anchor system, roof cap, roof cap opener, ladders and associated components (if

applicable).

• See Section 5.3. – Roof Ladder Details on page 28

• See Section 5.4. – Remote Roof Cap Opener Installation on page 30

• See Section 5.5. – Bin Entry Anchor System: Non-Structured Roof on page 33

5.3. Roof Ladder Details1. Locate the roof panel containing the roof ladder components to the left or right of the inspection hatch, and

in line with the outside ladder.

2. Recommended (for convenience): Attach the ladder and a section of the outside ladder early, when the roofsection is at ground level.

3. Start at the bottom with the longest ladder rung supplied and move up the roof using progressively shorterladder sections.

4. Bolt ladder rungs to the roof panel ribs using the pre-drilled holes in the ribs.

5. Use 5/16" x 1-1/4" hex bolts and hex nuts (bolts above and nuts underneath).

NoteMake sure that a STL/NEO sealing washer is installed between the last part and the roof sheet.


198863 R3 29

NoteThe ladder rung is oriented with the vertical portion facing up towards the peak ring. When a ladderrung is located at a double hole pattern designed for a roof-ring element, bolt through the upperholes and fill the other hole with a 1" hex bolt. No ladder rung is used at a roof-ring location. Thering itself will serve as a step. This ladder rung can be discarded or saved for another job.

15'-48' REMOTE CAP OPENER PIVOT ARM INSTALLATION

Once the eyebolts and the LH/RH springs are on the pivot arm, the best way to hook the 'legs' of the pivot arm into the bracket is to let the arm hang towards the ground to keep the springs 'loose' as the illustration shows. Caution must be used when bringing the pivot arm up when attaching it to the roof cap due to the force on the springs.

5.6. Lifting Wide-Corr® Bins with CranesThe table below lists the maximum height and weight limits for each diameter of bin which Twister approves forlifting by the roof using a crane. These limits assume that the total lifted load is evenly distributed around thepeak ring, through the use of a lifting tripod or similar device of adequate strength. Any bin exceeding EITHERthe height or weight limit MUST be lifted using jacks or similar method which supports the wall sheets directly.

These limits are critical. Failure during lifting carries the risk of serious injury or death.

Table 7. Lifting Weights for Various Bin Sizes

Bin Diameter Scribe Radius Maximum Tier Height Approximate Weight18’ 8’ 10-11/16” (2.710 m) 7 5,200 lbs21’ 10’ 4-9/16” (3.164 m)

8 9,000 lbs24’ 11’ 10-1/2” (3.619 m)

Important Safety Notes• Limits above are based on safe lifting of the bin only. They are not based on design factors for lifting people

or objects over people. Adequate safety blocks or supports must be used when working under or near thebin wall.

• Extreme caution must be used when lifting bins more than a few inches, as occurs when mounting bins onhoppers. “Bouncing” of the load and/or wind gusts can add significantly to the loads on the roof and couldcause overloading and/or failure.

• Please refer to any additional capacity information, lifting instructions, and safety information provided bythe crane manufacturer.

5.7. Inspection Hatch Details (15’ – 54’)Installation of inspection hatch (15’ to 54’)

1. Place the inspection hatch gasket (235882) around the lip of the inspection hatch opening. Trim the gasketto fit if necessary.

2. Bolt on the hatch lid assembly (235890) with 5/16” x 1” bolts provided for the roof. For best sealing results,the bolt heads should be on the underside of the roof panel, with the sealing washers pressed against theroof panel.

3. Bolt on the latch assembly (235891) as shown below. The latch is positioned on the center hole of the roofpanel and bolts through the top ring angle as shown.

The Grain Gauge™ and reflective strip comes packaged in the parts box.

The cut-out for the Grain Gauge is located in a separate top tier wall sheet. Position this sheet for maximum benefit (usually facing the direction of the auger that will be loading the bin). The Grain Gage wall sheet can also be rotated to position the Grain Gauge at two possible positions…an upper position for smaller augers and/or larger bins and a lower position for larger augers and/or smaller Install the reflective strip on the center web of the cut-out as shown. Caulk around the outside of the boltholes on the Grain Gauge™ flange with the 1/16” x 3/8” tape caulking supplied. Fasten the GrainGauge™ to the decal sheet using grain bin bolts with the indented upside down “V”

INSTALLATION IF GRAIN GAUGE CUT-OUT NOT PRESENT

1. Using the grain gauge, position the grain gauge

at a desirable location on the bin. The normal location is such that the top holes in the grain gauge are centered in the second corrugation valley below the top horizontal row of bin bolts at the eave (see diagram).

2. Mark and drill out holes using a 3/8” drill. 3. Next mark and cut-out the two slots, using the holes as a reference, according

to the diagram. 4. Install the reflective strip on the center web. 5. Install the grain gauge using bin bolts with

the indented upside down “V” at the bottom.

Note: Do not position the joint between two adjacent top ring angles directly over the Grain Gauge™ cutout. Insure that the top angle “bridges” the cutout and that the closest joint is at least 2 or 3 holes away. On bin diameters 27' and larger, it will be necessary to field drill the top two Grain Gauge holes through the top ring angle.

BIN ROUNDNESS It is imperative that the bin be as perfectly round as possible. The use of a string anchored and centered on the concrete foundation to scribe a circle is required (see chart below for calculated radii. These radiuses are 3/4" smaller than the wall sheet radius at the bottom, so that the scribed circle can be seen during assembly). A perfectly placed ring of sheets should be 3/4" on the outside of this line all the way around. This should be the first step in assembling a bin. The maximum amount that a bin can be out of round is 3/4" on the radius, when measured from the center of the bin. In addition the wall sheets must form a smooth circle with no flat or elongated portions. Before anchoring the bin to the foundation, ensure again that the bin is round, within tolerance. Locate anchor bolts towards the outside of the anchor bolt holes (away from bin) to permit the incremental expansion that can occur with the initial filling.

BIN JACK TECHNIQUES

We recommend:

1. Ensure jacks are sized for the job. Do not exceed rated capacity.

Have jacks evenly spaced around the bin.Each times

AnchorUse guynecessarystability.

Bin may also be erected using an internal jacking system.

(not available from Westeel)

Page E13

1. Choose a hoist with a suitable capacity for expected load. Make sure the rated capacity of the hoist is notexceeded.

2. Fabricate custom lifting lugs to suit assembly equipment. Each lug should have a capacity 5 times theexpected load.

3. Have jacks evenly spaced around the bin. Use one jack per wall sheet. Each jack should have a capacity 5times the expected load.

4. Anchor jack securely. Use guy wire if necessary to ensure stability.

5. Use a minimum of 4 – 3/8” x 1¼” bolt (Grade 8) not supplied to fasten lug, if one jack per wall sheet is used

NoteBin may also be erected using an internal jacking system.(not available from Westeel)

5.14. Hopper Cone to Bin InstallationNew Bin Application

Use only Westeel Hopper Cones which are specifically designed to suit Westeel Wide-Corr Bins. When installinga hopper cone to a new bin installation refer to the following instructions:

1. Pour the foundation as per instructions provided with your hopper.

• Ensure the foundation has fully cured before continuing the assembly of your bin.

• If a Westeel skid base is used, a compacted gravel base can be used instead of a concrete foundation.

• Follow the soil bearing information and site preparation instructions in Section 3. – Before You Begin onpage 9.


198863 R3 43

2. Assemble the bin as per the instructions in Section 5. – Assembly on page 18.

• For wall sheet layouts for the 15’ – 24’ bin for hopper, refer to Section 5.15. – Wall Sheet Layouts - EFSSeries on page 45.

• The bottom ring angle and door installation instructions may be disregarded when your WC bin isinstalled on a hopper cone.

3. Position hopper cone on foundation and align hopper with bin as shown in Figure 28 on page 44.

• Ensure all bottom holes on the bottom wall sheets are clear of bolts.

4. Use of a bin crane to lift your bin is recommended.

• Ensure the crane and all other lifting devices have adequate capacity to handle the maximum bin weightsafely.

• Lift the bin by placing a round support or 'tripod' inside the bin, directly under the vent collar.

5. Leave the vertical seam bolts loose on the bottom tier only for easy assembly.

6. Align the bin with the cone as shown in Figure 28 on page 44.

7. Fasten the bin to hopper cone with 3/8” x 1¼” bolts, nuts and washers.

8. Insert one bolt on one side, the next bolt on the opposite side of bin, then the next two bolts at right anglesto the first two.

This will position the bin on the hopper properly.

9. Once the bin is in place, insert all other bolts and tighten the loose bolts.

Important

• Use only lifting devices of adequate rated capacity.

• Make sure the hopper cone is level and all load points contact the foundation.

• Make sure all fasteners are tightened as per torque instructions in Section 7.5. – Recommended BoltAssembly on page 57.

7.5. Recommended Bolt AssemblyWhen tightening bolts, tighten the nut on the bolt until a “snug-tightened condition” has been achieved. A“snug-tightened condition” is defined in Specification for Structural Joints Using ASTM A325 or A490 Bolts(Research Council on Structural Connections: June 2004), which states:

“The snug-tightened condition is the tightness that is attained with a few impacts of an impact wrench or thefull effort of an ironworker using an ordinary spud wrench to bring the connected plies into firm contact.”

A properly tightened bolt will compress the sealing washer noticeably. All assembly crew members must bemade aware of this requirement, and must know how to achieve a snug-tightened condition using common bin-building tools.

It is important that the bolts in the vertical wall sheet seams are tightened enough to squeeze the caulking andbring the wall sheet surfaces into firm contact with each other. This is especially important to monitor wheninstalling bolts in temperatures approaching -10°C (14°F).

The following table shows the minimum impact gun torque capacity necessary to achieve a snug-tightenedcondition for bolts used in the assembly process.

Table 14. Recommended Impact Gun Torque Values Capacity to Achieve Snug-Tightened Bolts

5/8” Grade 8.2 1800 150 2033/4” Grade 5 3230 269 365

For proper sealing, do not overtighten the wall seam connections. Sealing is not critical on upright spliceconnections; these connections should be tightened securely to prevent loosening.

Hold the bolt head securely when tightening the nut to prevent damage to the sealing washer.

ImportantALWAYS TIGHTEN THE NUT, NOT THE BOLT!

Avoid bin assembly at temperatures below -10°C (14°F) if possible. Erection in low temperatures does notensure strong, well sealed connections. Do not substitute bolts in place of those supplied by Twister.
