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. 3.1. PRE-ASSEMBLY 3.1.1. SITE SELECTION The selection of the site is the most important step in erecting a Twister hopper bin. Choose a firm, level, well-drained site preferably on a small hill or rise so that snow and water cannot collect near the grain bin. The soil should have a bearing capacity of at least 3,000 lb/ft 2 Check for bearing capacity if there is any doubt at all about its adequacy. Top soil is not adequate for the support of a hopper bin and must be removed prior to the construction of the bin. The foundation does not extend below the frost line in some market areas and may be subject to frost movement with some soil conditions. If in doubt about the site location, hire a professional engineer who is familiar with local conditions. Table 3.1 Bearing Capacity Material Capacity Dry consolidated clay 10,000 Compacted coarse to fine sand 8,000 Sandy clay 5,000 6,000 Silt 3,000 4,000 Stiff clay 3,000 Soft clay <2,000 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 is allowed to become saturated with water. In general, a compacted gravel base is the only safe preparation for a foundation. Hopper bins must not be located next to high buildings that may cause snow to build-up unevenly on the bin roof or cause uneven wind pressure. Both can result in bin damage. BNH-10354 R7 11

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 Twister 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 30 for assembly instructions. CONE CAULKING ROWS (3/16 BUTYL) THROAT Figure 3.1 Hopper Throat 2.

STEEL FOUNDATION All Twister hopper combos may be supported using our steel, bolt-together 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. Twister steel foundations are for use with hopper bottoms manufactured by Twister 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 3.5. Steel foundations must be placed on a layer of gravel of sufficient depth and compaction, and must remain level to within ± 1/2 after loading. See Figure 3.5 and Tables 3.2 and 3.3 for the appropriate base for your hopper. 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. 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. H H H Figure 3.5 Steel Foundations Assembly 14 BNH-10354 R7

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: Important: 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 3.9 3.11). 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 Twister 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. 18 BNH-10354 R7

3. ASSEMBLY TWISTER - HOPPER BINS - BOTTOM 3.3. 14 HOPPER BOTTOM ASSEMBLY 14-3 22-8 MODELS 3.3.1. 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. 3.3.2. 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. See Sidewall Ladder on page 45. NOTICE Stiffeners vary in thickness (gauge). If the stiffeners are improperly installed, the bin could collapse once filled with grain. 24 BNH-10354 R7

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 3.14. 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 3.13 shows how the left and right top leg bracket pairs must be oriented in relation to each other. 7 LEFT BRACKET Figure 3.13 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 3.14. Bolt the splice brackets to the ring beams as shown. 4.

3. ASSEMBLY TWISTER - HOPPER BINS - BOTTOM 3.3. 14 HOPPER BOTTOM ASSEMBLY 14-3 22-8 MODELS To assemble the hopper cone: Note: Note: 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 12 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 3.18). 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. 1 3 22 Note: Figure 3.18 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 3.19). If you are going to use Round Tube aeration system, install the Rocket inlet cover plate to block-off Rocket aeration inlet (Figure 3.20). 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. 28 BNH-10354 R7

3. ASSEMBLY TWISTER - HOPPER BINS - BOTTOM 3.3. 14 HOPPER BOTTOM ASSEMBLY 14-3 22-8 MODELS 3.4. 19 & 22 HOPPER BOTTOM ASSEMBLY The 19 hopper bottom is meant to be used under galvanized steel Twister 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 Twister 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 Twister bin. If using the hopper on an older Twister flat bottom bin, call Twister 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.

TWISTER - HOPPER BINS - BOTTOM 3. ASSEMBLY 14-3 22-8 MODELS 3.3. 14 HOPPER BOTTOM ASSEMBLY 3.4.1. 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. 3.4.2. 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 3.28. 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-10354 R7 37

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. 3.4.5. LEG BRACES For Size See Figure: See Tables: 19 Hopper Bottom Figure 3.26 Table 3.5, 3.7 22 Hopper Bottom Figure 3.27 Table 3.6, 3.7 1.
