If I had a garage shop, I would have a pallet jack. I would make my own pallets for the heaviest equip. Not the light duty stuff, or find the heavy pallets. With some welding of tubes, you could make it so you have a removeable fence on the pallet for when you need to stabilize a load. just plug them in when needed and strap the load to the tubes to prevent it from tilting / falling. just like a fork lift. Also the nice thing about a pallet jack is you are not flattening the wheels, since you don't keep weight on them. I have gone through many wheels lately, the polyurethane type fail over time. If you mount any equip on casters, get the solid metal, or the thin tired with a metal hub. Just my opinion.
