    Congrats on learning to fly the 140. You made me smile. I had one, sold it in the mid 90’s. It remains a great memory.

    I'm glad your operator caught the fire early.
    Any landing you can walk away from, right?

    This is a project we did in 2016-2017 and maybe into 2018. The storage tank that is already erected was built in 2016. The new foundation is for a tank we built in 2017. The tanks are 135' in diameter Eave height is 91'. Each tank holds 1.25 Million bushels of corn. Total weight of the tank is 900,000 pounds. the foundation is elevated about 10' above grade. There is a walk through tunnel 6' wide beneath it with 6' 6" of head clearance. The tunnel house a conveyor that moves grain at 20,000 BPH back to the elevator and onto trucks or pumped into the feed mill to make hog feed. The conveyor system on top is also 20,000 BPH. 098.jpg

    Don't blame me for the cluster of tank and equipment. I didn't design it. LOL. They had a 600,000 storage tank collapse and demolished a lot of equipment. We installed four elevators in one steel structure. One is for receiving grain. One is for reclaiming grain. One is to move dry grain from the grain dryer. One is to put wet grain into the dryer. All 4 can operate at one time moving grain in different directions at the same time. 090.jpg

    The crane in these pictures is a Grove 165 ton. It has 197' main and a luffing jib. I forget the length of the jib but should be 70' or so.

    Seen this. Made me think of you and the projects you work on. Are grain bin sizes growing faster then the technology or engineering to keep them together. Kinda leads me to another question. How thick are the walls on a bin that size. 850,000 bushel is a good size. I can’t imagine how much pressure is on those walls at the bottom.

    There are several Bunge locations not far from where I’m at and it seems they’re always adding on and building even bigger bins.

    I just read about that failure this morning. Being in the business first thing I wanted to know is what brand is it? That site is owned by Bunge. That wasn’t a typical corrugated tank. It was a welded tank originally designed for oil stoarge. It had smooth sidewalls. From what I have heard these tanks have steel welded floors also and no foundation. Compacted rock base. Or at least that is what I was told. Bunge used a lot of this style tanks years ago. Typically painted white

    I have to wonder if the failure could have been a dust explosion? I know that things like flour can explode from just a spark. But would expect to see a little black soot if that was the cause.

    There are many reasons a grain tank like that can fail. If it is unloaded off center is one way. They could fill it, partially unload it, refill numerous times and cause it to fail. Differential settlement could cause it. Dust explosion.

    I have seen several fail and 100% have been in winter. Expansion/contraction?

    The big tank I built a few years ago busted. There must have been 50 engineers investigate it. No conclusions. But every local farmer that has aivkup truck knows why it failed.

    I heard some speculation that the reason the tank at Bunge failed was because they had put a skid loader door in the side just last year.
