11 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS 3.1. PRE-ASSEMBLY 3. Assembly WARNING Before continuing, ensure you have read and understand the relevant information in the safety section. Safety information is provided to help prevent serious injury, death, or property damage PRE-ASSEMBLY SITE SELECTION Selection of an appropriate site is a very important step prior to assembling a grain bin. The following must be adhered to when choosing a bin site: Choose a firm, level, well-drained site, preferably at the top of a small hill or incline so that snow/water cannot collect near the grain bin. The soil needs a bearing capacity of at least 3,000 lb/ft 2 (143 kpa) when using an AGI-designed foundation. Check bearing capacity if there is any doubt about its adequacy. If building a hopper bottom bin, refer to that manual for further information on concrete foundation requirements. Top soil is not adequate for the support of a grain bin and must be removed prior to assembly and replaced with packed gravel fill. The foundation may be subject to frost movement. If in doubt about the site, hire a professional engineer who is familiar with local conditions. Some materials that seem adequate at one time of year may become unstable later. Dry clay, for example, may lose practically all its strength if it becomes saturated with water. Grain bins should never be located near high buildings that may cause uneven snow build up on the bin roof or uneven wind pressure on the structure; both may result in bin damage. Bins should be positioned a safe distance from power lines or electrical transmission equipment. Contact your local power company to obtain recommended equipment clearance information. Electrical control equipment in contact with the bin must be grounded and installed in accordance with local codes. Determine your electrical needs for assembly and ensure that there is the correct type and a sufficient amount of power to operate tools, air compressors, lighting, etc. Ensure that there is sufficient power to operate any aeration or unload equipment that is to be installed. Orientation: Consider door (if equipped) and vent placement, loading auger direction, and unloading auger direction when choosing a site. BNH R8 11

12 3. ASSEMBLY AGI - HOPPER BINS - BOTTOM 3.2. HOPPER LADDER PACKAGING MODELS SITE CONDITIONS Access routes to the site and within the site should be given on a site plan showing dimensions and level of access routes, level of the prepared working area for site traffic and plant, and areas available for storage. Construction of the bin shall not start until the following site conditions have planned for and evaluated for safety: provision and maintenance of hard standing surfaces for cranes and access equipment; access routes to and within the site should be included on the site plan; soil conditions affecting the safe operation of the structure; possible settlement of erection supports for the structure; details of underground services, overhead cables or site obstructions; limitations on dimensions or weights of components that can be delivered onto the site; special environmental and climatic conditions on and around the site; particulars of adjacent structures affecting or affected by the works CHECK SHIPMENT Unload the bin parts at the assembly site and compare the bill of materials to the shipment. Ensure that all items have arrived and that none are damaged. It is important to report missing or damaged parts immediately to ensure that proper credit is received from either AGI or from your AGI distributor/dealer, and to ensure that any missing parts can be shipped quickly to avoid holding up the assembly process HOPPER LADDER PACKAGING 14 HOPPER LADDER PACKAGING For all 14 hopper bottom orders for European Union countries, the hopper bottom section ladder parts (braces, stringers, standoffs, and rungs) are packaged with the bin that will be paired to the hopper bottom. 19 AND 22 HOPPER LADDER PACKAGING For all 19 and 22 hopper bottom orders for European Union countries, the hopper bottom section main ladder parts (stringers, standoffs, and rungs) are packaged with the bin that will be paired to the hopper bottom.

13 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS 3.2. HOPPER LADDER PACKAGING BOLT TIGHTENING All the bolts that are required to assemble the hopper bottom are supplied. When tightening bolts, tighten the nut on the bolt until a snug -tightened condition has been achieved, as defined in Specification for Structural Joints Using ASTM A325 or A490 Bolts (Research Council on Structural Connections: June 30, 2004), which states: The snug-tightened condition is the tightness that is attained with a few impacts of an impact wrench or the full effort of an ironworker using an ordinary spud wrench to bring the connected plies into firm contact. All bolted connections must be tightened to a snug-tightened condition, and any mention in this manual of tightening bolts indicates tightening to a snug-tightened condition. All assembly crew members must be made aware of this requirement, and must know how to achieve a snug-tightened condition using common bin-building tools SEALING INSTRUCTIONS FOR ALL BOLTED HOPPER BOTTOMS Follow the instructions below to protect the hopper against water entry and grain leakage. Use the 3/16 butyl caulking roll and the grey MultiFlex caulking tubes provided. If additional sealing is desired, additional tubes of MultiFlex are available from your dealer or you may purchase another thermoplastic sealent. It is important to use a thermoplastic sealant for a proper seal. Do not use silicone. 1. Apply 2 rows of 3/16 butyl caulking to the throat (one row on each side of the bolt holes) before fastening the throat to the cone, as shown in Figure 3.1. See Hopper Throat and Slide Gate on page 34 for assembly instructions. CONE CAULKING ROWS (3/16 BUTYL) THROAT Figure 3.1 Hopper Throat BNH R8 13

Hopper bin support legs must be laid out on a common circle, bolted in place on the common radius within ±10 mm (3/8 ). Adjacent support legs must be equally spaced within ±10 mm (3/8 ) measured between column centers. A concrete pad used to support a hopper bin must be flat, smooth, and level within ±5 mm (3/16 ) as measured across opposite sides of the pad. Piles must be collectively level within ±5 mm (3/16 ) as measured across pile pairs that are furthest apart. BNH R8 15

16 3. ASSEMBLY AGI - HOPPER BINS - BOTTOM , 19, & 22 HOPPER FOUNDATION MODELS Note: For steel skid foundations, the compacted gravel base under the foundation must be flat, smooth, and level within +5 mm (3/16 ) to -15 mm (9/16 ) as measured from any base point of measurement on the gravel base that supports the steel skid. For both concrete pads and piles, differences in level between adjacent support legs can be addressed with metal shims as long as the overall tolerance is not exceeded.

Center-to-center. b. Center-to-center STEEL FOUNDATION All hopper bottoms may be supported using our bolt-together steel foundations. However, it is very important that these foundations be supported with an adequate, compacted, gravel base to ensure that they will not shift and cause the structure to fail. Steel foundations are for use with hopper bottoms manufactured by AGI and are not warranted for use with any other make of hopper. The following precautions must be taken: Proper site preparation is critical! Topsoil will not provide adequate support for the foundation. Remove all loose, organic, or wet soil from the area around the foundation as shown in Figure BNH R8

17 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS , 19, & 22 HOPPER FOUNDATION NOTICE Compacted gravel base must remain level. Any out-of-level condition on the foundation will cause deformation or failure of the bin sidewalls and hopper components. Steel foundations must be placed on a layer of gravel of sufficient depth and compaction, and must remain level to within ± 3/8 after loading. See Figure 3.6 and Tables 3.2 and 3.3 for the appropriate base for your hopper. The foundation must make contact with the gravel base all around the perimeter of the foundation. Gaps between the gravel and the foundation are not permissible. The foundation and hopper must be anchored to prevent the structure from overturning in the wind when empty. The hopper should be placed on high ground in a well-drained location. Center the assembled skid over the desired location of the hopper.

21 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS , 19, & 22 HOPPER FOUNDATION CONCRETE FOUNDATION Important: Concrete foundations will provide the safest support for any hopper bin. It is highly recommended that hopper bins greater than 5 tiers high (Models 14-5, 16-5, 19-5, 22-5) and all hoppers in permanent locations be supported with concrete foundations. When placing a concrete foundation, the following precautions must be taken: Choose a well drained location with a minimum soil bearing capacity of 3,000 lb/ft 2. If soil bearing capacity is not known, consult a local engineering professional. Remove all topsoil and construct a concrete pad for the appropriate hopper size (Figure ). The perimeter beam and slab must rest on coarse gravel compacted to 3700 lb/ft 2 and should rise above the surrounding soil. Use 3,000 lb/ft 2 in concrete and reinforcement as shown. The hopper bin must be anchored to the foundation to prevent the structure from overturning in the wind when empty. If you have purchased a concrete form from AGI and will reuse the form, install the leveling brackets on the exterior of the form. Install the bolts on the inside and the nuts on the outside of the form for easy removal. BNH R8 21

This will include bins manufactured by AGI as well as some other manufacturers bins commonly referred to as 14 bins. This hopper is designed for use on a new AGI bin. If using the hopper on an older AGI flat bottom bin, call AGI for advice concerning additional stiffening that may be required. 24 BNH R8

25 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS HOPPER BOTTOM ASSEMBLY Ensure that the hopper will fit on another manufacturer s bin before beginning any assembly work. Call manufacturer if you are unsure. AGI has no control over the manufacture and design of bins made by other companies and does not accept liability for any property loss, injury, or death that may result form the use of such bins. NOTICE Many bins used in flat bottom applications are not adequately stiffened for use on hoppers. Failure to ensure that the design is sound and safe may result in damage to bin and/or personal injury.

27 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS HOPPER BOTTOM ASSEMBLY ASSEMBLY METHODS (14 ) There are two common methods used to assemble 14 hopper bottoms. The first method is to build the hopper bottom onto a hopper top that is supported by a bin crane, beginning by adding segments of the ring beam and working with the sequence presented in this manual until the full hopper bin is complete. The second method is to build the hopper bottom fully, using whatever sequence is preferred by the assembler as long as it follows the principles set out in this manual. To assemble the full hopper bin, use a bin crane to lift a hopper top onto the hopper bottom. For both methods, it is important to ensure that specific bolts on the hopper top are loose before the ring beam and the hopper top are joined together. Before joining hopper top to the hopper bottom ring beam, it is important to ensure that: All bottom-tier hopper-top stiffener bolts are sufficiently loose (nuts placed fully on bolts, but not tightened). All bottom-tier hopper-top vertical seam bolts are sufficiently loose (nuts placed fully on bolts, but not tightened). These stiffener and vertical seam bolts can be fully tightened only after the hopper top is fully connected to the ring beam of the hopper bottom with 3/8 x 1-1/8 bin bolts inserted from outside the hopper top. WARNING When lifting or supporting a hopper top with a crane, always ensure that the crane is rated for the load (including weight of hopper bottom if required) and has sufficient reach height and reach angle to lift, support, and place the hopper top BIN PREPARATION Before placing the bin on the hopper, the bin sidewall ladder must be positioned on the ring beam for the hopper ladder to fit properly. NOTICE Stiffeners vary in thickness (gauge). If the stiffeners are improperly installed, the bin could collapse once filled with grain. BNH R8 27

28 3. ASSEMBLY AGI - HOPPER BINS - BOTTOM HOPPER BOTTOM ASSEMBLY MODELS HOPPER BOTTOM RING BEAM Note: 1. Raise the bin to a comfortable height and bolt the ring beams to the bin wall. Make sure the name sheet is centered over the center of a ring beam; this will allow the hopper ladder to line up between the two A-frame columns. 2. Bolt the top leg brackets to the splice brackets as shown in Figure The top leg brackets come in right and left parts. Plan ahead to get the name sheet centered between two columns as shown in the Sheet and Stiffener Layout in the Hopper Top manual. Figure 3.14 shows how the left and right top leg bracket pairs must be oriented in relation to each other. 7 LEFT BRACKET Figure 3.14 Left and Right Leg Bracket Orientation RIGHT BRACKET 3. Apply a strip of 3/16 caulking to the back of the splice brackets as shown in Figure Bolt the splice brackets to the ring beams as shown. 4. Double check the orientation of the top leg brackets /16 CAULKING Figure 3.15 Splice Bracket Assembly 5. When all the ring beams are fitted to the bin wall and the splice brackets are fitted to the ring beams, tighten the bolts in the bin wall. When this is done, tighten the bolts in the ring. 28 BNH R8

Relative locations of the manhole, Rocket and Round Tube aeration inlet cone sections are dependent on your site plan no matter what type of aeration system you are planning to use. Figure 3.18 shows an example layout of the hopper cone sections. MANHOLE CONE ROCKET AERATION INLET CONE ROUND TUBE AERATION INLET CONE Figure 3.18 Example Layout of Hopper Cone Sections 30 BNH R8

31 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS HOPPER BOTTOM ASSEMBLY Note: Note: To assemble the hopper cone: 1. Based on your site plan and your preferred locations of the fan and unload system, determine the position of the Rocket or Round Tube aeration inlet and manhole cone sections; and then, plan the cone assembly accordingly. See Sealing Instructions for all Bolted Hopper Bottoms on page 13 for cone sealing instructions. Leave the manhole or Rocket/Round Tube aeration inlet cone section for last. This will make inserting the last bolts much easier. 2. Offset the cone sections 1 bolthole clockwise relative to the ring beams (Figure 3.19). One side of the cone sections is bent in towards the center of the cone. This side should be to the right, as viewed from the center of the cone, and under the next section Note: Figure 3.19 Cone Section Assembly 3. Install the remaining cone sections, including Rocket and Round Tube cone sections, following step 2. If you are going to use Rocket aeration system, install the Round Tube inlet cover plate to block-off Round Tube inlet (Figure 3.20). If you are going to use Round Tube aeration system, install the Rocket inlet cover plate to block-off Rocket aeration inlet (Figure 3.21). If aeration system is not desired, cover both aeration inlets with their respective plates. The bin that is to be assembled on the top can be clocked in any orientation independent of the bottom cone. BNH R8 31

38 3. ASSEMBLY AGI - HOPPER BINS - BOTTOM 3.5. INSPECTION HATCH ASSEMBLY DETAIL MODELS & 22 HOPPER BOTTOM ASSEMBLY The 19 hopper bottom is meant to be used under galvanized steel AGI bins that are 720 in circumference or 19 in diameter, and the 22 hopper bottom is meant to be used under galvanized steel bins that are 838 in circumference or 22 3 in diameter. (Diameter is measured to the inside corrugation of the bin wall.) This will include bins manufactured by AGI as well as some other manufacturer s bins commonly referred to as 19 or 22 bins. This hopper is designed for use on a new AGI bin. If using the hopper on an older AGI flat bottom bin, call AGI for advice concerning additional stiffening that may be required. Ensure that the hopper will fit on another manufacturer s bin before beginning any assembly work. Call the manufacturer if you are unsure. Important: Stiffeners should be placed no further than 5 apart if the bin is to be used on a hopper. NOTICE Many bins used in flat bottom applications are not adequately stiffened for use on hoppers. Twister does not assume responsibility for any failure or damage caused by the use of products built by other manufacturers.

41 AGI - HOPPER BINS - BOTTOM 3. ASSEMBLY MODELS 3.5. INSPECTION HATCH ASSEMBLY DETAIL ASSEMBLY METHODS (19-22 ) The standard method used to assemble 19 and 22 hopper bottoms is to build the hopper bottom fully, according to the sequence outlined in this manual. To assemble the full hopper bin, use a bin crane to lift the hopper top onto the hopper bottom. Other methods or variations are acceptable as long as they follow the general principles of assembly outlined in this manual. Regardless of what method is used, it is important to ensure that specific bolts on the hopper top are loose before the hopper bottom ring beam and the hopper top are joined together. Before joining hopper top to the hopper bottom ring beam, it is important to ensure that: All bottom-tier hopper-top stiffener bolts are sufficiently loose (nuts placed fully on bolts, but not tightened). All bottom-tier hopper-top vertical seam bolts are sufficiently loose (nuts placed fully on bolts, but not tightened). These stiffener and vertical seam bolts can be fully tightened only after the hopper top is fully connected to the ring beam of the hopper bottom with 3/8 x 1-1/8 bin bolts inserted from outside the hopper top. WARNING When lifting or supporting a hopper top with a crane, always ensure that the crane is rated for the load (including weight of hopper bottom if required) and has sufficient reach height and reach angle to lift, support, and place the hopper top HOPPER COLUMNS Note: 1. Steel Foundations Only: Secure the square columns to the skid in the locations provided with two 1/2 x 1-1/2 hexagon head bolts through the base plate. Washers will be required as the holes are oversized. Refer to Table 3.5 for quantities. Ensure the brackets on the columns are facing the centre of the skid. 2. Concrete Foundations Only: To ensure columns are positioned correctly, construct the jig shown in Figure The single hole is placed in the center of the foundation and the first pair of holes on the outside will be the location of the column holes. 3. Concrete Foundations Only: Rotate the jig about the center to get the spacing shown in the column locations figure. BNH R8 41

Fasten the top cone sections to the ring and to each other using just enough 1/2 x 3/4 flat head bolts to hold them in place. 2. Bolt the bottom cone sections to the inside of the top cone sections using just enough bolts to hold them in place. 3. Use the wind brace to keep the cone sections from bending. The wind brace is bolted to the leg above the stop provided using u-bolts, to the seam of the cone at the sixth and seventh hole from the bottom for the 19 bin, and where the spacing between holes is 4 for the 22 bin. 4. Once the entire cone is assembled, the rest of the bolts can be placed. Often simply pushing up on the seam will bring the bolt holes into alignment. 5. When the cone is completed, the throat (item #10) can be bolted to the outside of the cone with 1/2 x 1 hexagon head bolts LEG BRACES For Size See Figure: See Tables: 19 Hopper Bottom Figure 3.28 Table 3.5, Hopper Bottom Figure 3.29 Table 3.6, Fasten leg braces to the inside of the ring beam with two 3/8 x 1-1/8 bin bolts and to the outside of the column with one 1/2 x 1 bolt supplied in the leg. 2.
