Can you explain this setup, better.

Are grain bins, rare, in your area?

Is your "concrete contractor" unfamiliar with grain bin forms/design?

Will these bins, have an aeration floor, in them?

Are you trying to explain something, like this? (see photo)

Here's what a lot of guys, like better;  =  higher concrete base = gets a straight unload auger, high enough to get a second auger underneath

Even if your "crop" is dry, that system isn't any type of unload auger setup, that 99.99% of people would like (meaning, the sweep auger couldn't go all the way around, the bin)

I don't know why, they (or you) wouldn't want a flat, straight unload,(parallel with the ground) then add a 45 degree incline to it (If you don't want to pay for the additional concrete to raise the entire bin higher)

Many people, now-a-days, prefer a straight unload = it eliminates a u-joint in the 45 incline, and it can flow/unload faster, too(with a straight, flat unload) I believe it takes less HP to for the electric motor, also.

Old days, with straight unloads, AND with short concrete base, MANY farmers always had to dig a hole, to get their second auger, underneath the bin's unload, just to get the grain out.(nobody like that= that's why taller concrete bases are more common, today)

Does this look like what they want to do?

Edit: If this guy, has done thousands of bins, with this floor design; then someone should reply.

OK, this is a sweep auger, that you must carry inside the bin, every time.

That's helps us understand, better.

Most of us, were thinking of a permanent "power sweep" type of sweep auger setup, with gearbox inside.

WOW ! no wonder it's cheap !  

I doubt the sweep will go 3/4 of the circle.

So the loadout is NOT in the cement ??  A BUNCH more grain that will NOT flow out, MORE for the sweep that doesn't sweep
Isn't the point NOT to shovel ???

Get some references and go look at some, doubt that would fly "here"

Tubes SUCK !!   do full floor and loadout can lay on crete pad under air floor, simple clean FULL air IF you need it and a sweep that is a sweep!

This guy is selling him a BIG LOAD !!  It don't sound right at ALL!!

I think the point we were trying to get across is people have found a better system that works better for them.

I know drying is not an issue just trying to get a sweep that makes a full circle and empties the bin with least effort, which is important to a lot of shovel-aged backs

perhaps this is an alternative

Get a SPRINGLAND Sweep & unload U trough.  Maybe a   few more $$, But  you'll never regret it.   For the $$$ your spending it's peanuts.

 I'd show you mine,,,, but they are under 70,000 bu of Barley.

So how much grain do you scoop to empty the bin?  

Most bin jacks work off the floor, do you pour a footing, then come back and finish floor when bin done ?

I guess in this part of the world or what I'm most familiar with is pour floor, build bin, put in air floor and loadout, bin done.

On a lot of jobs nobody does all the steps so doing one and moving on to next works best

I know there is no air floor and I think that's a foolish thing, weather it's "needed" or not the one time there is a need it would pay

Putting a sweep in an old bin saves labor, putting it in the way that is being talked about creates labor, seems odd.

Beings you already have on and really like it, why did you bother to ask?

Must be a location thing.

 Seems like that works for you guys, in a drier environment, with a dry product.

I know, my brother, has done some repair work, for a guy, that had a concrete cones, poured inside bins walls, with auger sticking out at an angle = what a mess; ground moisture, seeps up thru concrete and spoils grain (in this environment)
