A coworker of mine made a skating ramp with a few of those for the kids. He was so proud he even made another one for his town park.
Last summer while leveling my backyard I had to move the kid's playhouse, you know, the one at Costco that comes in 6 or 7 boxes, weights a ton and takes a week part-time for an average joe like me to build, even though they wrote 8 to 10 hours on the box?? Yeah, I had to move it to the front yard so I took off the slide, then the 10" pole for the swings, then I made SKATES out of pallet wood and small wheels to roll it to the front. It rolled on plywood pretty easily

However because it was only in temporarily in the front one day the wind blew so hard it knocked it on its side but nothing broke because my garbage bin was under and slowed down the fall.
Other than that, maybe buy two forklifts: one to put on it, then another to lift it and move it around?
Just DONT do what of my towns residents did last month: jack up his house with a car jack and secure it down with pallets... The house torn in the middle and fell on him and his neighbor.
