6. Sidewall Assembly How to use charts on this page: The chart titled “body sheet chart” is for the reference when building the tank. This chart tells you how many rings the specific tank must have. To read the chart you look up the tank size you wish to build (an 18' diameter tank with 4 rings will look like BFT18' 4 rings).
6. Sidewall Assembly Sidewall Erection 12'-21' Bulk Feed Tank 12'-21' Diameter Bulk Feed Tanks are designed to be built vertically utilizing bin jacks or a crane of adequate capacity. Before bolting the sidewall sheets together, check that you have the proper gauge steel for the first ring.
Page 29
6. Sidewall Assembly Figure 6F Figure 6E IMPORTANT: BOLTING PATTERN BEGINS IN THE CENTER OF THE SHEET. When starting to assemble the sidewall rings to one another. Be sure to start in the center of the sheets and work to the outside edges (horizontal seams). This allows the sidewall sheets to draw up evenly.
7. Roof Sealed Roof Panel Installation (12'-18' BFT) Roof to Sidewall Note that the roof and sidewall ladders are centered on a roof seam. Take notice when placing roof panel, that one edge is bent down. This edge is to be placed on the outside of other roof panel to form a tight seal.

7. Roof 12' 60° Roof Cap Ground Control Ground control comes standard on 12' 60° Bulk Feed Tanks. Ground control is optional on all 45° Bulk Feed Tanks. Ground control components come fully assembled for the convenience. The ground control is shipped with the arm secured for safety and shipping purposes.

7. Roof Roof eave bracket (BLK-11950) Figure 7P After removing the slack from the ground control chain while in the fully closed and latched position. Install the key ring clip 2" below chain holder bracket. (See Figure 7Q.) Ensure that the key ring allows the cap to fully latch when the cap is in the closed position, yet will not allow the chain enough slack on top of the cap to become wrapped around the pivot arm in a high wind condition.
Page 39
7. Roof Make sure the loop of the main cap spring (BLK-11623) is held securely in the pre-loaded position by the head of the 5/16" bolt beneath. Figure 7R If necessary, place one or more 5/16" flat washers under the bolt head to ensure that the bolt catches the loop.

7. Roof Roof Cap Bulb Seal Kit (Optional) Bulb seal (BLK-10472) Figure 7U Cap Hold-Down Package Figure 7V Bulb Seal is pressed into place around the lip of the peak ring. NOTE: Bulb seal kit is included with all pneumatic fill kits. When ordered as a separate option, specify part# BLK-10472.
7. Roof 15' and 18' Roof Assembly Instructions After completing first ring assembly, you are ready to begin roof construction. First, build a roof center support to hold the peak ring in place at the proper height. A simple structure consisting of a sturdy cross arm attached to a pole and supported by a platform or scaffolding will do.
7. Roof Raising the Roof NOTE: See 30° roof manual (PNEG-1092) in roof hardware box for instructions on 12',15',18' & 21' grain bin roof. Figure 7AB Anchor Tank Before 2 Ring Assembly Anchor all jacks securely with metal stakes and cables (use one jack per sidewall sheet). Now raise the tank just enough to assemble the next ring.
Page 45
7. Roof Figure 7AC A crane of adequate capacity attached to a spider assembly with cables connecting at each vertical sidewall seam just above the legs can also be used to lift the tank. Make sure the tank is being lifted smoothly and evenly.
8. Hopper Assembly Hopper Sheets When starting to attach hopper sheets to sidewall it is recommened that the first hopper sheet seam be positioned halfway between leg positions. Lap the hopper sheets as shown. Use two (2) strips of caulking on all seams at sidewall to hopper and hopper sheet to hopper sheet.

8. Hopper Assembly Hopper Collar Assembly 45 Degree 22" Hopper Collar BLK10854 60 Degree 22" Hopper Collar BLK10342 Install hopper collar before all hopper panels are assembled. Use 5/16" truss head bolts, as shown in the illustration, on all hopper seams. Be sure to caulk between the hopper collar and hopper panels. Refer to drawings.
9. Legs and Leg Bracing Installation of Leg to Sidewall Figure 9D Use 5/16" x 3/4" bin bolts and nuts when attaching the leg to base. Make sure the washer is used on the slot side of the leg. When installing legs to sidewall, reverse normal insertion procedure on bolts. Place hex head and neoprene washer to inside of sidewall, leaving threaded portion of bolt protruding outward.
9. Legs and Leg Bracing Installation of Leg to Sidewall for 15', 18' and 21' BFT When installing legs to sidewall, reverse normal insertion procedure on bolts. Place hex head and neoprene washer to inside of sidewall, leaving threaded portion of bolt protruding outward. This provides for a weather tight seal at the leg attachment location.

9. Legs and Leg Bracing Hopper to Leg Bracing Hopper braces are to be spaced equally around tank. Hopper braces are required on all hopper tanks. Refer to the chart below for the quantities required. NOTE: Hopper braces attach between the legs and the collar/hopper horizontal seam. Never bolt the braces directly to the hopper seam above the collar.
10. Ladder Optional Sidewall Ladder To start sidewall ladder, places two (2) outside standoffs spaces 18-3/4" apart. At the roof eave, the ladder should be located on the standoffs. (Refer to drawing). Continue with standoff located on every horizontal seam. Ladder support ring should be located between two legs as shown. This will standoff the ladder at the bottom of bulk feed tank.
Page 62
10. Ladder Start attaching ladder at the eave (top) of the Bulk Feed Tank. After the first ladder has been attached to the sidewall of tank, attach ladder extension rails to the ladder as shown in Figure 10F. Refer to Page 61 for proper ladder placement in relation to the eave of the tank.
11. Raising Bin Raising Bin to Set on Foundation Be sure that all bolts are tightened properly. The bulk feed tank can now be set up on foundation. A crane of adequate capacity attached to a spider assembly with cables connecting at each vertical sidewall seam just above the legs will usually do the job.

12. Grounding NOTE: Parts not supplied by manufacturer, they should be purchased locally. All bins shall have two (2) ground connections. Ground clamps must be placed at equal distances around the bin. Alternate installation: Cables may be placed in the foundation or through PVC sleeve inserted in the slab during construction.
Figure 13A Roof Panel Identical pre-punched roof panels are available from GSI for inlet and outlet sections of pneumatic fill systems. Extruded lip of the panels provide for weather tight installation. Caulking placed between angle rings virtually eliminates all leakage problems.
