PNEG-1070 15', 18', 21', 24', 27' and 30' CHT’s 41
Begin assembling the two (2) piece hopper bottom by attaching a right and left pair or pairs of the top
hopper panels to the compression angle ring (3/8" x 1" bin bolts (S-455) and 3/8" nut (S-456)), along with
the back side splice plates which use (3/8" x 1-1/2" bin bolts (S-5060) and 3/8" nut (S-456)). Refer to
Figure 6F . All top panel seams use 5/8" x 1" hardware (S-4210) and 5/8" nut (S-4110). Once the top panels
are positioned the bottom hopper panels may be attached to the top panels and discharge collar with
1/2" x 1" hardware (S-4492) and 1/2" nut (S-3729), at four (4) opposing points as shown in
Figure 6D .
A 5/8" x 2" bolt (S-4329) and 5/8" nut (S-4110) is used on all corners of the spliced hopper panels. Refer
to
Figure 6E for bolt usage on hopper panels. Caulking is required on all vertical and horizontal seams of
the hopper bottom, (refer to Figure 6G ). Complete this assembly by laying in alternate right and left panels
moving around in one direction and lapping all sheets the same way. Do not tighten bolts until all hopper
panels are attached to each other, the compression ring, splice plates and discharge collar.
30' Commercial hopper tank has two (2) piece hopper as shown.
27' Commercial hopper tank has two (2) piece hopper as shown.
