Our first shipment of grain bin "pieces and parts" was delivered:
and off-loaded to be stored until time to build:
The long strips on the trailer are floor slats. The curved bars on the forklift are roof supports. We also received roof sheets:
Each stack of pie-shaped wedges will make one roof. The variety of lengths corresponds with the diameter of the bin. That oval cut-out will become a man-hole for access to the grain stored inside.
And of course a bin has to have walls:
These stacks of curved sheets will form the "rings" of the bins. Bins are measured by diameter and height (number of rings). The stack in the center will build bins with a 36' diameter. The stack on the left will build 24' bins, so they are curved a little tighter. There's a lot of detail about farm bins vs. commercial bins, the width of the rings, etc., but you get the idea. The crates above the center stack hold the nuts and bolts of the business - literally. There are more than 1000 bolts in an average grain bin. Each one is inserted by hand by a crew member on the outside of the bin and tightened by a crew member on the inside, using an impact wrench.
When the weather warms up, we will start pouring concrete pads and erecting bins. (And by "we" I mean Dave and a crew of 6 guys.) Bins are built from the top down. First the roof is constructed then jacks are used to raise it far enough to insert the first ring underneath.
Then two rings . . .
Four rings . . .
Six rings . . .
And the 9th and, in this case, final ring is in place. Time to start raising the second bin.
Next comes floors, spiral staircases, doors and installation of an auger. This process takes 1 or 2 weeks - depending on bin size - including time to pour concrete, let it cure for several days, erect the bin and add finishing touches.
