I have moved heavy equipment by jacking it up an inch, and putting 1" steel rods under it.
I have seen others do this too.
Works well, and you just take the rod as it comes out the back, and move it up front (requires several rods).
They moved an old steam locomotive that was on display in this city by placing one section of track on the ground in front of it, rolling it forward, and them moving the back section of track forward.
They did this for about 200 yards until they got the locomotive over to an active train track.
Its all about leverage and balance.
I watch the videos produced by Barnhart, the hoisting company, and they are the masters of threading some very tight needles with some very large/heavy equipment, such as for nuclear plants, etc.
They have extremely creative solutions, and some custom equipment.
