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
in Figure 8D and Figure 8G
on Page 48 . Use two (2) strips of caulking on all seams at sidewall to hopper and hopper sheet to hopper
sheet. Use 5/16" x 1-1/4" bin bolts (head to outside of tank) for attaching hopper sheets to bottom sidewall
sheet. Use truss head bolts to attach hopper sheet to hopper sheet. Be sure to place the head of the truss
head bolt on the inside of the hopper. Leave one hopper sheet out to allow room to install the hopper collar.
Be sure to use two (2) strips of caulking between hopper collar and hopper sheets, then put last hopper
sheet in place. After the collar is in place, attach the hopper braces and tighten all bolts.

Install hopper sections. When starting to attach hopper sheets to sidewall it is recommended that the
first hopper sheet seam be positioned halfway between leg positions. Lap the hopper sheets as shown
in Figure 8B and Figure 8C on Page 47 . Use 5/16" x 1-1/4" bin bolts (head to outside of tank) for attaching
hopper sheets to bottom sidewall sheet. Use truss head bolts to attach hopper sheet to hopper sheet.
Be sure to place the head of the truss head bolt on the inside of the hopper. Caulk all seams (double bead).
