PNEG-1092 30° Bin Roof Construction 27
For best results in erecting the roof, install two (2) roof panels in four (4) places as shown in Figure 7C.
When these eight (8) panels are in place, the peak assembly should be centered. Next add two (2) or
three (3) panels at a time to each section making certain to lap them the same way, until all panels are in
place. Be sure the panels are bolted loosely. DO NOT TIGHTEN BOLTS UNTIL THE ROOF IS
COMPLETELY ASSEMBLED. When installing the roof panels, take into consideration placing the
manway for ease of access to and from the sidewall and roof ladders. On Stiffened tanks, particularly
on NCHT and FCHT series hopper tanks, location of the manway panel and roof ladder in relation
to the stiffeners is crucial for proper installation of the ladder system. Refer to PNEG-1451
for detailed instructions on NCHT and FCHT manuals and PNEG-1420 for flat bottomed
stiffened tanks (FCDL, NCL, WCL Series). These manuals are packaged with the ladder and
safety cage packages.
Fasten roof sheets to eave clips and sidewall sheets as you assemble.
