Faunsdale, AL | When we moved the 24' bins I mentioned above, we used two old power co boom trucks, one on each side, lifting with a spreader between the lift points so they didn't deform the bin any more than we could help it. We used 16' 6x6 timbers with a plate bolted to each end that had a notch for the chain so the timber would stay in place and we could go up a ladder and attach a bracket with half a dozen bolts to a vertical seam between two sheets and then hook the lifting chain in the bracket. The lifts ended up being spaced equally around the circumference of the bin. If we had had a crane with enough reach, we would have used a wheel in the center of the roof to lift , but we had the trucks for free, so we made that work.
We sat each section down on a flatbed trailer with 16' 6x6's bolted to each side and swung across the 8' trailer to hang out 8' on the opposite side. This put the two beams just a bit smaller than the diameter of the bin if you measured tip to tip. We bolted a short section of 4x4 or 6x6 cross ways underneath the ends of the outriggers with all-thread rod, so the bearing surface for the bottom of the bin sheet was the same height as the deck of the trailer. The short piece being cross ways spreads out the bearing surface so you don't bend the bottom of the upper section of the bin as badly. It helps to shim up the main beams where the middle of the beam bears on the edge of the trailer with something like a 2x board. This puts the free end of the outrigger higher than the deck of the trailer, but the beam will flex down as the weight comes on it and the bin will bear more evenly on the trailer deck and the outrigger beams.
The bottom section of each of our bins had full aeration floors, so we ran a couple pieces of 3x3 tubing across the floor, bolted brackets welded on the ends into the wall of the bin and then screwed through some tabs welded on the tubing and into the floor "planks" in 8 or 10 spots across the bin on each piece of tubing. This held the floor, sump and unloading auger tube in place during the move as well as helping to keep the bin round. The hardest thing we had to do was remove, load, haul, unload, and rearrange the cinder blocks that were used as floor supports. If you have to deal with that, make a picture or two to refer to! We were able to arrange them on the new foundation and set the bottom half of the bin down on them, but we should have had a diagram or picture to speed it up.
