5. Locate a threaded stud (F) and install stud nuts (G) evenly and to the center of the threaded
stud (F).
6. Install the threaded stud (F) with stud nuts (G) to the end of the roof ring section (B).
NOTE:
Install the threaded stud (F) to the side where the next roof ring section (B) will be installed.
7. Repeat this process, installing each new roof ring section (B) end onto the preceding threaded stud
just installed.
8. When all roof ring sections (B) are installed, tighten each roof ring clip (C) to the recommended
torque specifications. Refer to
Bolt Torque Specifications, page 26
.
9. Adjust each stud nut (G) outward, expanding each roof ring section (B). Continue this procedure
evenly until the roof ring raises the roof, showing a slight crown.
NOTE:
Expansion bolts should be fully contracted when assembling support rings. When you have
completely assembled both rings, (but prior to expanding the bolts) tighten all roof bolts
including eave clip bolts. Now extend expansion bolts by running the nut out on the threads.
This procedure should be continued evenly around the roof until the ring raises the roof to
show a slight crown.
NOTE:
Roof ring expansion bolts may become dislodged from the roof ring during the life of the bin
due to the influence of wind or other factors. If one expansion bolt is dislodged, the entire
ring will become ineffective. After expansion to the jam nuts final position, the nuts on the
expansion bolt should be secured to prevent this. This may be done by staking the
expansion bolt threads at the jam nut location, use of suitable thread locking compounds or
other effective methods.
In addition, drilling holes through the support pipe and expansion bolt and connecting
together with a 1/4 in. diameter bolt is an effective way to prevent the bolt from dislodging
during certain wind and pressure conditions.
