I do not want to make little machines for this. My MIL has a shed with the middle and one outer runner on her patio slab. It is about 12'x16'. Insulated and finished inside with electric, AC/heat, etc. It is her artist/she shed/sanctuary. Needles to say the runner on dirt has allowed it to tilt. I only need to move it 12 to 16" to have all three runners on the slab. There is 3.5" between the slab and under side of the shed. My jack will not fit in there. I have thought of drilling anchor points on the slab to use a come-a-long to winch it over. Vehicle access is limited by soggy yard and limited space. Any millwright ideas out there or am I on the right track?
I do have steel dowels and aluminum plates, but I am limited to not having a jack to lift it up so I can place them under it.
I looked at that page and got an idea. nuts bolts and pipe. I'll have to look at my collection. I'm thinking 3" long bolts and nuts in a 2" piece of pipe would give me a simple jack that would fit in the 3.5" space between the shed and slab. Kind of how these jacks work:
can you post up a photo of the shed you are going to move.
I second sunbelt rentals for a jack or come-along
enerpac makes all kinds of lifting pushing gear, I have been busy this afternoon evaluating our stuff for service. can you safely raise it up and place it on pipes to roll it?
Borrow an engine crane. Run a lag bolt into the end of the runners, hook the crane to the lag, and lift. Lift it enough to get a jack underneath. Or, lift enough to put 4 casters under it, at each end of each runner that's on the slab - then dolly it over and drop it down.
Why not just fix the sagging end of the shed? Dig a hole deep enough for a bottle jack, take the sag out, and drop it back down on some new concrete footings, or shim up the ones that are already there. They may have settled all they're going to settle.
Can you get at the studs? when I needed to move my neighbors 14x22 garage he was adding on and I got it for the cost of moving it. I jacked up the building off the slab, backed a car trailer into it, (and here's the part relevant to your job), face nailed a ledger to the studs. I reinforced the ledger with hurricane ties at the top, then laid rafters across the span and over the trailer bed.those were secured to the ledger with upside down joist hangars. that allowed the weight to be borne by the inside "rafters" on the trailer. In your case, the ledger would be along the sole plate and tied to prevent the walls from spreading as you winch and tug the building.

OldDog, Sorry, I haven't been back down there to get a pic of the shed. It is most the way onto the slab and only needs moved about a foot sideways, dragging the runners sideways instead of long ways. I may have figured out how I am moving it.
I picked up a larger lower floor jack for $20 on market place.
It is lower with the cup removed.
If need be, I can lower it another 1/2" by removing wheels.
In fig.1 I have 3.5" between the shed underside and the concrete slab. In fig.2 is my plan to jack it up and place a pipe or plank at an angle then lower the shed so that it takes a step sideways.
This might be old fashioned however how about 2X4's and hammer in wedges to lift it up to get more wood under it?? This way you can crib it up to the height you need. It's a slow process however it is less expensive.
