Need to move an 800+ pound concrete slab.

Too bad you can't ask the Egyptians who built the pyramids. Their slabs were a whole lot bigger and they didn't even have tractors!

Or TBN to consult.

Why is it used in concrete bridge construction? Is it just to make cleanup easier after the bridge collapses?

If rebar doesn't add structural strength, why is it used at all?

CalG explained that simply and accurately. All concrete cracks.

I don't know how the Egyptians managed without TBN.

I've found there is a ratio that moves toward success or prohibits it. This ratio is the amount of time spent doing the task versus the amount of time spent thinking/talking about it. The project will move that ratio a bit. But in the end the doing part completes the task.

I poured a 32' x 60' for one of my barns and used fiber and steel , kept a sprinkler on it for about 12 hours a day after the first 48 hours for about a week and cut an expansion joint at the center length ways and cross ways and it hasn't cracked yet, but it may anytime, but it's made 16 years.

Have you looked closely inside your cuts?

I cut my shop into 10ft squares. Filled the cuts with expansion caulk so it would be easier to clean. No cracks anywhere on the surface. But I can't see in my cuts. If/when it cracks it will be in the cuts.

Maybe I should re-phrase, there are no visible cracks on the surface or sides of the slab , there easily could be cracks inside of my expansion joint cuts, I anticipated that on the very end and side of my slab where my cuts ended that it would crack all the way to the bottom of the slab but it hasn't as of yet.

I'd use chain, not cable. Edges of concrete slab may cut individual cable strands.
On this old farm, which used to use horse power, I found a number of 4" diameter dowels about 4 feet long, which I believe were placed under heavy objects. As the heavy object was moved off of one dowel, it was place in front of the heavy object, to be used again in the move. Probably 3 or 4 dowels at any one time under the heavy object.
If you have a centered hook on your FEL, I think you'd not have a worry about torqueing something. Chain that slab. You may not be able to lift it, but you can diminish the weight on the ground as you drag it to the new location.

My great grandpa moved a big house 1/2 mile using mules and logs. Then they lived in it. It was big one.

No argument there. Perhaps I should have said "break it in half" instead of just "break it" in my original post. A cracked slab held together with rebar may still be useful whereas one that is broken completely in half may not.

We are using those things to move heavy metal

This one is 6 tones

That will not help OP, as those rollers work only on hard surface.

To equalize weight long round bars has to be used. Like fence posts



Another "lazy option" worth to try is would be to put that thing on some sheet, try to lift one end with 3p and then try to pull it then as sleigh.

To not spoil cables and that slab, put between cables and concrete old thick textile. Like old jeans, towel, anything like that
