The ones I've been on you can feel the roof flex when you walk around. That said, I don't think they'll spontaneously fall over or anything....Most grain bins felt similar.

The railings literally move about 4 inches under about 20lbs of pressure. The railings meet the absolute minimum required to comply with OSHA, and even that is a bit doubtful.

That doesnt look all that stable so you might need to run a stabilizer bar off. thats what we have done, no pics though. 34db im guessing is 3' or more, so I dont know that this would have enough beef for that On Wed, Apr 22, 2015 at 9:37 AM, Mark Radabaugh <[email protected]<mailto:[email protected]>> wrote: This is probably the best picture I have of what we did with one of those silos. Your silo looks identical to the one we are on: [X] The railing, as you noticed, is very wobbly. At the base of the vertical unistrut are L brackets. We took one nut off the top of the tank and secured the bottom of the L to the stud. The two unistrut cross bars were mostly to give us a mount for the 900 omni, but they also serve to stiffen the structure side to side. You may want to run more of those on diagonals to further stiffen it. Front to back stiffness is provided by the threaded rods that you can just make out in the foreground on the right side of the picture. The threaded rods pull in on the railings while the unistrut keeps the 'circle' of the handrail from collapsing inward. The overall assembly is reasonably stiff for the load we have on it. For a bigger dish you may want to substitute something stiffer than the threaded rod front/back. Adding a cross brace between the walkway rails would help stiffen the entire assembly but would block the walkway and might be politically unacceptable.

We should be able to remove two bolts from the seams and install a metal plate for a U-bolt to solidify the bottom, and U-bolt to the rail at the top. That would be plenty solid for sectors, but debating bringing back some sort of bracing arms for the BH mount. I know many of you have sites on top of silos. Anyone willing to share mounting methods and techniques and/or pictures? -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
