Installing Wind Rings (Continued)
1. Install a wind ring bracket (B) to each stiffener (C) using flange bolts (A) and flange nuts (D).
Figure 13C Wind Ring Bracket
2. Tighten hardware to the recommended torque specifications. See bolt torque specifications
on Page 25 .
3. Place a wind ring section (E) into the channel of the wind ring bracket (B) and install a C-clamp (I),
securing with flange bolts (H) and flange nuts (J). Do not tighten until all wind ring sections
are installed.
4. Repeat this procedure, inserting each wind ring section (E), over the previously installed wind ring
section, securing the wind ring sections together with flange bolts (F) and hex nuts (G).
5. Before installing the last wind ring section (E), slide a wind ring coupling collar (K) over the wind ring
section (E).
6. Install the last wind ring section (E) and cut the wind ring section to the proper length.
NOTE: The cut needs to be made in a location that allows minimal space between the pipes.
7. Slide the wind ring coupling collar (K), aligning the three (3) pre-drilled holes and install flange
bolts (F) and hex nuts (G). Field drill the remaining three (3) holes (L) using the wind ring coupling
collar (K) as a guide or template.
(See Figure 13D on Page 93.)
8. Install the remaining flange bolts (F) and hex nuts (G) and tighten all hardware to the recommended
torque specifications. See bolt torque specifications on Page 25 .
NOTE: When installing the wind ring bracket to a 2.66" close
punched stiffener, use the bolt holes marked 1, 2, 4 and 5 as
shown. When installing the wind ring bracket to a 2.66" far
punched stiffener, use the bolt holes marked 1 and 5 only.
Hole marked 3 will not be used on all 2.66" bins. Flange bolt
hardware length may vary with sidewall gauge thickness.
