Now as I turn my attention to a coal bin I need to make it mobile. The reason is where the chute will be is not where I want the bin to be. So I was thinking of making a 4'x4'x8' bin mounted on a 4x4 grid and have casters. I may need a small Comalong to move it straight across the basement.
Thoughts?? Ideas??
Thanks,
Tom

Base frame made of 3" I beam with crossmember at 4 ft mark and steel wheel casters for weight. might be cost prohibitive? 3/4" PT plywood floor ? maybe SS diamondplate? actually 2 separate 4x4x4 might be easier handling.

small guage railroad track..... 8-)

The casters for the 4x4x8 will be expensive.
4x4x5 will hold 2 ton. add 9"for the wheels and 6" for floor structure and will fit under most overhead obstructions.
There are roller and rail systems for moving the bigger bin if you are just moving in a straight line.

One of the guys local to me has a unique system in his basement that you may be interested in. He went to a local scrap yard and picked up five or six sheetmetal shipping crates. He reinforced them as needed and uses a pallet jack to move them around his basement.
When receiving a load of bulk coal he brings each of them to the chute, loads in a ton and wheels it away and brings in another.
He keeps the crate he's using next to his hopper and feeds out of it until it's empty.
His next project was going to be a vacuum system to move the rice coal from the crate to the hopper.

On Craigslist or EBay I recently saw a used supermarket conveyor set-up like in use at the register. It would probably would great if you put it under your chute and then directed it where ever you wanted the coal to go. It might still be around - it might have been the Lehigh Valley CL.

If the basement floor is really smooth and level you may be able to push it by hand. Got to have good casters though.

I am thinking 10-12 casters. Found some on Grizzly tool. Rated @550 lbs. each for about $8.75.

An old treadmill works good for a short run

You need 10 casters for each 4x4 section, 20 for the 4x8.

A friend of mine is a body man and he keeps everything on casters so he can move projects around his shop. He has a 3/4ton on casters right now. He has them on two sets of 6" casters. The 4x4x8 should be of similar weight full or even less.

40 cu. ft is about 2000 lbs.
So if you do not mound the top, but everybody packs a few more on, you get 3.2 tons.
Add the weight of the structure; add another ton for mounding and another ton, at least, for safety margin.
The 4x4x8 bin on wheels needs to be able to carry 6 ton minimum 8 ton if you never want it to break.
The 4x4x4 starts looking good from a design standpoint. Make it 5 foot high and a bit of mounding will make it 2 tons, 6000 lbs for the casters to carry.

Everything built of steel to "never break" is built to five times breaking strength. If you are going to put a 2,000 pound load on a cable, it needs to have a breaking strength of 10,000 pounds. It's called "working load" and "nominal strength". That being said, most casters are rated in working load.

Cape Coaler,

My bin at my work place is 4 x 4 x 4. It holds 1 1/2 tons - I think I wrote on the outside max capacity 3270 lbs.
