Electrical SAFETYImportant consideration should be given to some or all of the following devices and to others which may be appropriate:

1. Overload protection devices such as shear pins, torque limiters, zero speed switches, etc., to shut off and lock out power whenever operation of equipment is stopped as a result of excessive material, foreign objects, excessively large lumps, etc.

2. Safety shut-off switch with power lockout provisions at auger drive

3. Emergency stop switches readily accessible wherever required

4. Electrical interlocking to shut down the feeding auger whenever a receiving auger stops

5. Signal devices to warn personnel of possible startup of auger, especially if started from another location

6. Special enclosures for motors and controls for hazardous atmospheric conditions

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


MGB1948B 11

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 MeasuresIf 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 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 Grain 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, and 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

Planning Before Your Bin Arrives BROCK® 15' - 48' Dia. Farm Grain Bin Construction Manual (Wide Corr.)

16 MGB1948B

Choose The 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 3,000 pounds per square foot [143.6 kPa].Foundations shall be appropriately designed for local soil and frost depth conditions.

Check DeliveryYour 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.

Body Sheet IdentificationEach Body Sheet is identified by Part Number, gauge and diameter. For further information, see the Body Sheet Part Number Listing and Layout Diagrams in this Manual, Pages 38-47.Tools and Equipment Needed• 7/16" - 1'' Box End Wrenches • Adjustable Wrenches up to 1-1/2'' [38] for adjustable expanders• 12'' [305] Long Drift Punches • Hammer• Screwdriver• Speed Wrench and Sockets• Impact Wrench and Sockets• Lifting Jacks• Lifting Brackets • Bolts for Lifting Brackets• Protective gloves, eyewear, earplugs, and steel-toed shoes• Nail aprons to hold a supply of Bolts and Nuts during assembly

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.

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 ConstructionIMPORTANT! 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 25-26.A 3/8'' Grade 8.2 Bin Seal Bolt has an approximate safe load of 2,650 pounds [1 202 kg].Tighten 5/16'' Nuts to 15-20 ft-lb of torque.Tighten 3/8'' Nuts to 25-30 ft-lb of torque.

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.

Choose the Proper Jacks to Lift the TankJacks are used to lift the Grain Bin slowly and evenly during assembly of the wall 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 Tank. 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 Tank under windy conditions! This could result in Tank damage. Read “SAFETY Procedures During Jacking” on the next 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 Tier of Body Sheets.

(Caulk horizontal and vertical seams.)4. Start assembly of each new Tier of Body Sheets on the windward side of the

Tank. See Figure 19.5. Leave all Bolts loose in the new Tier until all sheets have been attached.6. Attach Ladders Cages, and Platforms. 7. Repeat Steps 3 - 4 as new Tiers are being added. 8. Install the Door Access Sheets in the bottom two Tiers. 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 IdentificationOn an inside upper corner of each Body Sheet is a Sticker with the Part Number, gauge and Grain Bin diameter printed on it. See Detail A, Figure 20. This is helpful in locating each Sheet in the BODY SHEET PART NUMBER Listing and Layout Diagrams in this Manual, Pages 38-47.

IMPORTANT!

Caulking Is Critical!Wipe the Body Sheets clean where the Caulking is to be applied. All Body Sheet seams are caulked with a bead of Caulking inside the line of holes. Be sure to follow caulking instructions carefully. Use these guidelines:

Where 20- through 13-gauge Body Sheets will lap: use one 6'' [152] strip.

Where 12- through 9-gauge Body Sheets will lap: use two 10'' [254] strips.

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

Adding Tiers: Intermediate Body SheetsWhen the Roof is complete and lifted, proceed to adding lower Body Sheet Tiers below the top Tier of Body Sheets.

Body Sheets on a completed Tier are caulked on the inside, below the row of horizontal Bolt holes on drying Grain Bins.

The bottom edge of the upper Tier always overlaps outside the Tier of new Body Sheets being installed below. Vertical seams are staggered.

IMPORTANT: Stagger the vertical seams.Order of Assembly:1.Along the bottom of each Sheet (A in Figure 24) on the Tier above, place Sealant

as shown where the two lower Tier Sheets will lap.

2.As each new Tier is added, assemble lower Sheet B to the upper Sheet A and follow with Sheet C.

3.Assemble Sheet C to Sheet B.

4.Repeat this method throughout the Tank.

IMPORTANT! Horizontal Seams are fastened with Bin Seal Bolts and Hex Nuts. All Bolts must be tightened from the Nut side. Use a drift punch to align horizontal holes and insert Bolts, heads on the outside.

1. Assemble each Body Sheet in a Tier using the Sealant method shown on Sheet B in Figure 24.

2. Along the top and bottom of each Body Sheet, place a strip of Sealant below the horizontal seam as shown on Body Sheet B where the Tier laps. Use the following amount of Sealant as a guideline:

Where 20 through 13-gauge Body Sheets will lap: use (1) 6'' [152] stripWhere 12 through 9-gauge Body Sheets will lap: use (2) 10'' [254] strips.Caulk as close to holes as possible. Use plenty of caulking. Overlap Top Body Sheets outside of Bottom Body Sheets.3. As each new Tier is added, assemble Sheet B to Sheet A and place the Sealant on

the end per Body Sheet B.

Anchoring AssemblyConcrete must be level to within 1/4" [6.4] in 10 feet [3 048] and 1/2" [12.7] total. Any high spots or debris must be removed before setting the Tank. See Page 22 for the number of Anchor Bolts required.Install adequate Anchor Bolts in the Concrete.Refer to the Foundation Manuals for your Grain Bin.The Tank must be anchored securely to the Foundation. Shims or grout must be used to fill any gap. Sweep concrete to remove excess dust. Wipe underneath the side of the return flange/Base Angle to remove excess oil.The bottom of the Tank must be sealed using one of these methods:With the Grain Bin slightly suspended, apply a heavy layer of black mastic (or Saturated Foam Sealant, Part No. 9-44600 or Butyl Rubber Foundation Sealant, 475836) to the underside of the Bottom Body Sheet flange/Base Angle.Saturated Foam Sealant must be compressed to one-fourth of its original thickness to provide a weathertight seal. Any additional Sealant should be placed only on the inside of the Grain Bin.Splice the Strips and seal low spots:Cut the Sealant at a 30-degree angle with wet scissors and pinch together. The Sealant will expand back to the original cross-section.After all Sealant is in place, slowly lower the Tank down onto the Foundation. Tighten all Anchor Bolts to help compress the Seal Strips.Properly installed Sealant does not require tar or other additional sealers.

Special In-Bin Drying InstructionsBROCK® Grain Bins are offered in both a Standard and heavy series (C) for specific uses. In order to maintain the BROCK® Warranty, the appropriate “series” Grain Bin must be used. See the BROCK® sales catalog or contact the Manufacturer for recommendations.

CAUTION! Additional loads on the Grain Bin sidewalls, Roofs and Floors can be created by improper drying methods. If high-moisture grain is loaded too deep and too fast, any unstiffened Grain Bin wall can be overloaded and damaged. It is suggested that you observe the following instructions to avoid Grain Bin damage.

1. Level the load to 3-4 ft. [914 - 1 219] of wet grain into the Grain Bin and dry-down to a 16% moisture before adding additional wet grain. This procedure must be followed until the Grain Bin is full. If the Grain Bin is equipped with a stirring device, it is suggested that it be run continuously while filling, and the initial grain filling depth not exceed 6 ft. [1 829]. This grain must be dried to 16% moisture content before adding additional grain. If these procedures are not followed, and the filling rate exceeds the drying rate, wall sheet roll-down will occur. The reason for this damage is: the bottom grain dries and shrinkage develops, allowing the above wet grain to be supported only by the Grain Bin wall. Damage generally develops in the area of the drying front.

2. If the stirring device is to be stopped, stop it with the down-augers near the center of the Grain Bin.

If the device stops or stalls for any length of time, the auger carriage must be supported by the grain surface before restarting. Turn off all power and rotate the vertical augers by hand (use a pipe wrench) to free them up before restarting.

Care should be taken not to load grain into the Grain Bin above the level of the stirring device; otherwise, Grain Bin wall and/or Roof damage could occur during unloading.

3. The preceding notes are general operating instructions.

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