Use a transit and surveyor’s rod to locate high and low areas in the concrete, before placing the support
columns on the anchor bolts. To assure level alignment, use the proper supplied shim or shims between
the concrete and base plate. After leveling, place the support columns over the anchor bolts, on the shims
and loosely fasten with nuts and washers (not supplied). Refer to
Figure 6A on Page 39 .
NOTE: 27' (8.23 m) Diameter hopper tanks have 18 columns.
30' (9.14 m) Diameter hopper tanks have 20 columns.
Figure 6B Compression Angle Erection
Using 5/8"-11 x 2" hardware (S-4329), fasten the inside and outside vertical compression angle segments
and splice plates to the support columns,
See Figure 6A on Page 39 and Detail G in Figure 6C . Next,
attach the horizontal channels with 5/8"-11 x 1-1/2" hardware (S-4109) to the inside and outside
vertical compression angle segments and the support clips on the support columns, as shown in
