An unrecognized issue isn't being addressed. Height is a no-no when rigging, every inch costs something, including tiedowns and center of gravity 'COG'. A drop [best] or tilt deck [usable] is a good start. Forklifts aggravate COG, when every machine has high COG anyway. Add the slippery surface of the forks, unless you have a sheet of interlock [rubber bonded plywood] that is trouble from word go. I toe jack for rollers or skates, and winch or pinch bar where I want to be. BTW; purchase two 60" pinch bars, and 2-3 30" prybars. Not a HF fan, but theirs are working well, even for a critical user. Jokingly, I call them chopsticks; because one is kind of useless. About rollers; more jacking needed but wood peeler cores work incredibly well over less than perfect surfaces, right over and absorbing little stones. 5 is a good minimum. They rarely are perfectly straight, no issue.
This brake weighs 2400+ lbs [calculated] heavy parts 5 feet high; did it on peelers into my 5' x 10' 3500 tiltbed. A boat winch on receiver tube is uber-useful. Note 'joists' tying pedestals together, and narrow footprint. No good locations for tiedown hooks, so looped slip-hooked chains with carpeting dunnage. Drove a rough 25 miles, rechecked bindings and completed 600 mile trip.
Seeing the move is completed, good on you for investigating and selecting the most reasonable combination of solutions. DO NOT let that induce confidence in the next move, only the process. We are not pros, not pro equipped, not pro manned, not pro experienced, not pro insured . . .Unless buying multiple identical items, picked up same location, equal weather, driving same route etc,
every time is different.
