DANGER! There are Suffocation Hazards in Flowing Grain!Never enter a Grain Bin of flowing feed, grain, or other material. Failure to follow these instructions will result in death or serious injury.

SAFETY

From the time the auger starts, you have 2-3 seconds to react.

In 4-5 seconds, you are trapped.

After 22 seconds, you are completelycovered.

Figure 5. Suffocation Hazards in Flowing Grain


10 MGB1945B

Safety Hazards and Recommendations1. Never enter a Grain Bin of flowing grain.

2. Never enter a Grain Bin when unloading equipment is running, whether or not grain is flowing.

3. Never enter a Grain Bin that has automatic unloading equipment without locking out the control circuit.

4. Never enter a Grain Bin that you do not know the nature of previous grain removal, especially if there is any crusting evident.

5. Always be cautious before walking on any surface crust.

6. It is always advisable to have three people involved, two on the outside and one inside, when entering a questionable Grain Bin/storage circumstance. The person in the Grain Bin should be secured or fastened to a safety rope with the two persons outside capable of lifting that person out without entering the Grain Bin. One person outside cannot do this, and cannot go for help and maintain preliminary aid.

7. Never work in obviously dusty-moldy grain without a respirator. Never work in such conditions, no matter what the protection, without a second person on safety standby. Use a respirator capable of filtering fine dust.

8. Be aware that your tolerance to a given material may be limited, and that you should not deliberately and knowingly expose yourself on the idea that “it won’t hurt me.” Later in life, you may have used up all of your tolerance.

9. Always be cautious when you are working with grain that is not in good condition. You can have molds, blocked flow, cavities, cave offs, crusting–it is time to be alert.

10. Never depend on a second person, either on the Grain Bin roof, on the ground, or any other remote point to whom you shout instructions to start or stop equipment.

a.Equipment noise can block out commands or cries for help.

b.The second person may fall or over-exert in the panic and haste of getting off the Grain Bin or running to the control point.

Possible Corrective Measures1. Install Ladders inside all Grain Bins.

2. If you must enter a Grain Bin with evident danger, use a rope and safety harness to support and lift you in the event of trouble.

Before it is too late . . . Talk to your children, your co-workers, and your neighbors about the above safety information. Their lives, your life, may depend on it.

Considerations that may result in a hazard, damage your Grain Bin and/or void your Warranty BROCK® Grain Bins are offered in several models for specific uses. In order to maintain your Grain Bin and its Warranty, the appropriate type Grain Bin must be used. Consult BROCK Grain Systems/CTB Grain Systems or your BROCK® Dealer.

Read and understand the Owner/Operators Manual and all SAFETY Decals.

Grain Bin damage can occur due to improper construction of the Grain Bin:

1. Use all hardware specified in the instructions and make no substitutions.

2. Refer to the Foundation Manual for proper Foundation specifications.

Radial cracks in the Foundation are a danger signal. The Foundation is growing outwardly, and is also pulling the Grain Bin with it. These forces can be large enough to cause Bolt damage in the vertical seams of the bin wall. It is suggested that if cracks are present they be monitored for any changes, and remedial action taken.

3. Stiffened Grain Bins must be leveled so a vertical dimension between adjacent Stiffeners does not exceed 1/8" [3.2]. If Stiffeners are not level, Bolts attaching the Stiffener to the Body Sheet—as well as the vertical and horizontal seam Bolts—may become overstressed and shear, causing total failure.

4. If the Grain Bin has a perforated Floor on columns/Floor Supports, and those columns fail due to improper installation, the Grain Bin can shift sideways, causing both sidewall and roof damage.

CAUTION! Cables to support conveying equipment such as bucket elevators or conveyor legs must not be attached to the Grain Bin roof or sidewalls. To do so would cause damage to the Grain Bin. Refer to your Roof Manual for construction of proper supports for such equipment.

WARNING! Additional loads on Grain Bin sidewalls, roofs and floors can be created by improper drying methods.

Grain Bin damage can also occur due to improper ventilation, loading and unloading of the Grain Bin:

1. When the Grain Bin is filled off-center;

2. When unloading is done from the Door or an off-center floor port, uneven wall pressures may occur, allowing the wall to flatten directly nearest the unloading point; damage can be seen above and several feet to either side of this area. In stiffened Grain Bins this failure may be seen in wall sheets nearest the unloading point. Severe Sheet seam and Stiffener damage can occur, causing complete Grain Bin damage. Internal grain pressures change when only a few bushels of grain have been removed. Grain Bin damage can be caused by incorrectly unloading even small amounts of grain.

SAFETY

BROCK® 12'-54' Dia. Farm Grain Bin Construction Manual (Narrow 2.67” Corr.) Planning Before Your Grain Bin Arrives

MGB1945B 15

Choose the Grain Bin SiteFor soil and foundation specifications, refer to Pages 18-21 in this Manual.

Select the site of your Grain Bin with care. Planning for future expansion is of prime consideration.

The soil area for your Grain Bin(s) should be firm and well drained with a uniform bearing capacity of at least 3000 pounds per square foot [14 647 kg/m2].

Foundations shall be appropriately designed for local soil and frost depth conditions. Check Delivery

Your Grain Bin is made up of many parts and checked carefully at the time of shipment. However, use the packing slip and check your shipment on arrival to be sure it is complete.

IMPORTANT! How to control “Wet Storage Stain” (RUST!) on galvanized Body Sheets: Do not permit moisture from weather, condensation, or other sources to remain between Body Sheets. If moisture is present, separate the Sheets IMMEDIATELY for good air circulation. Where possible, store all Bin components in a warm, dry place away from contaminants such as fertilizer, chemicals and road salt. If this is not done, white/red rust will appear.

The paper cover on the BROCK® Decal helps prevent damage to the Decal during Grain Bin construction. However, it may be difficult to remove if left in direct sunlight for several hours.

The BROCK® Decal is to be applied in the center of a Body Sheet in the first Ring down from the top.

Adequate Roof SupportThe Approximate Working Height* Chart in your Roof Construction Manual will be essential in planning the support of the Roof and/or Sub-Structure either by crane or center support. Be sure your lifting equipment is adequate for the height and weight of your particular Roof.

Adequate Tank Support During ConstructionRead and follow the information on Jacking on Pages 30-34 of this Manual.

IMPORTANT! The number of lifting jacks and brackets required is determined by factors such as Grain Bin size, soil compaction, wind velocity, design of jacks, etc. Read and follow the information on Jacks on Pages 28-29.A 5/16'' Grade 8.2 Bin Seal Bolt has an approximate safe load of 1,840 pounds [835 kg]. keep this in mind for the number of Bolts you use to lift Grain Bins during assembly.A 3/8'' Grade 8.2 Bin Seal Bolt has an approximate safe load of 2,650 pounds [1 202 kg]. keep this in mind for the number of Bolts you use to lift Grain Bins during assembly.Tighten 5/16'' Nuts to 15-20 ft-lb of torque.Tighten 3/8'' Nuts to 25-30 ft-lb of torque.

Placement of ComponentsMake a sketch and plan component placement of such things as:• Roof Stairs• Manhole Panel• Unloading Equipment• Roof Vents• Inside and Outside Ladders and Platforms• Guardrail access point• Doors• Filling Equipment• Fans• Side Discharge (outlet cannot be at a vertical seam)

Locate Anchor Bolts (not supplied standard with the Bin)Take your time. Accuracy will pay. Refer to Figure 16 and the Anchor Bolt Information Chart on the facing Page for measurements on your particular Grain Bin.

Layout locations and install anchors BEFORE setting the Grain Bin to insure proper location. Failure to do so may cause damage to the Grain Bin.

Use the center pipe and a board or chain again to make the correct diameter to set the Anchor Bolts. The Hilti® Anchor Kwik-Bolt, 1/2'' diameter x 7'', or an equivalent may be used.

The anchor must be at least 1/2'' [12.7] diameter with a minimum embedment of 5 1/2'' [139.7].

When Hilti®, or an equivalent type anchor is used, concrete must have 28-day strength to prevent pullout before setting the Grain Bin and tightening Anchors.

Construction Begins with the Top Ring of the Tank:IMPORTANT: No Caulking is used where the Roof sections attach to the Top Ring.

Top Body Sheets, Hardware and Caulking: (see the section “Assemble the Top Ring First” on Page 31 in this Manual)

Build the Roof on the Top RingAfter the Top Ring is built, consult your Roof Manual to build the Roof.

Read carefully the following sections on Jacks and raising the Grain Bin so that proper equipment will be in place to lift the construction.

Lift the Roof and Top Ring to continue construction of the Tank walls When the Roof is complete and the Roof/Top Ring are raised, return to this Manual and repeat the Body Sheet bolting/caulking instructions for the second Ring down. Repeat throughout the remainder of the Tank.

Further information as gauges change, see the BODY SHEET PART NUMBER Listing and Layout Diagrams in this Manual, Pages 36-39.

Accessories such as Ladders and Cages are installed every one or two Rings as the Tankis built and depending the length of the Ladder section. Refer to your BROCK® OutsideLadder Manual (MGB1538) or BROCK® Platform Manual (MCB1352) for properinstructions. Instructions are shipped separately with optional Accessory items.

Set, seal and ground the TankAfter completing the bottom Ring, level the Tank, shim the Stiffeners (if applicable), seal the base of the Tank and securely anchor the Tank to the foundation. See the section “Setting and Sealing the Grain Bin.”

28 MGB1945B

Choosing the Proper Jacks to Lift the Grain BinJacks are used to lift the Grain Bin slowly and evenly during assembly of the Body Sheets. The Jack shown in Figure 18 is only a representation. Jacks should be designed using accepted engineering practices, taking into account the dead and live loads associated with construction.

Jacks must be used on every Sheet on 42' - 48' [12 802 - 14 630] diameter Grain Bins. At least one jack for every other Sheet (every Sheet is best) for 15' [4 572] through 36' [10 973] is recommended.

Determine the number of jacks required for the weight of the Grain Bin. Jacks must be able to hold twice the weight of the Grain Bin. Bolts must be adequate for lifting the load. (Lift Brackets Bolts are not included in the Bolt count.)

IMPORTANT! The jack represented in Figure 18 is not adequate for all sizes of Grain Bins. On larger Grain Bins, electric or hydraulic jacks are recommended. Consult the jack manufacturer for instructions.

CAUTION! Do not jack the Grain Bin under windy conditions! This could result in Tank damage. Read “SAFETY Procedures During Jacking” on the facing page.

SAFETY Procedures During Jacking 1. Be sure Jacks and cables are anchored securely.

2. Position vertical seams at Anchor Bolts. Also verify locations of Roof Manhole, Ladders, Access Door and Side Discharge system before starting to raise the Tank.

3. When jacking, raise the Tank just enough to add one new Ring of Body Sheets. (Caulk horizontal and vertical seams.)

4. Start assembly of each new Ring of Body Sheets on the windward side of the Tank. See Figure 19.

5. Leave all Bolts loose in the new Ring until all Sheets have been attached.

6. Attach Ladders Cages, and Platforms.

7. Repeat Steps 3 - 4 as new Rings are being added.

8. Install the Door Access Sheets in the bottom two Rings. Install the Door.

9. Lower the Tank and secure to the foundation before the leaving the job site.

10. Follow the jack manufacturer’s recommendations for capacity and operations.

Body Sheet IdentificationEach Ring or layer of Body Sheets is identified by a color. Each Sheet in the Ring is identified by a number. A strip of colored tape with a number is located on the inside of each Body Sheet. This helps locate each Body Sheet on the chart.

Heavier gauge material is sometimes substituted for the Door Short Sheets.

Caulking Body Sheets

Wipe the Body Sheets clean where the Caulking is to be applied. No Caulking is used where the Roof sections attach.

Place a bead of Caulking along both sides of vertical and top side of horizontal holes before the next Body Sheet is attached. See Figure 20.

Caulk as close to holes as possible. Use plenty of Caulking. Overlap Top Body Sheets outside of Bottom Sheets.
