Trailer jacks is not a bad idea, and I have seen this sort of thing done
on other equipment. They are also available (at a substantial cost) at
much higher ratings. Having seen a few failures generally the
limitation of most lighter ones is the plastic wheel. I've seen them
break.

I found tongue jack replacement wheels in a discount store to add on with a longer axle.
Steel wheels aren't that hard to make. I welded crossed plates for spokes into a slice of 6" stainless pipe, bored the center a snug fit for pipe and welded it, then bored the pipe to accept needle bearings cut from stainless welding rod. These are the oversized all-terrain replacement wheels for my platform lift which is stored on sometimes wet ground.
The HF 1300 Lb electric winch starts with a considerable jolt and is meant to mount on horizontal pipe with the included straps. The cable would bunch up at an end instead of winding evenly if the winch was somehow hooked to a trolley hoist and could tilt.
I scratch-built a trolley with a flat bottom the winch bolts to. That was the project behind my posting of a few years ago about boring a recess to press in a bearing. Mostly I use this trolley with a chain or lever hoist hung from a central eye bolt because the electric winch is too hard to control precisely. When positioning a log or partly cut cant on the sawmill I lift it only enough that it can be slid into position and will stay there.
The electric winch was good for stacking logs because I could stand clear in case the pile shifted. Stacking cut timbers with it was a nuisance because it wouldn't partially support them while I aligned the stack.
