Wow, much more to consider then I had expected.

The plan had been to move the equipment into the workshop with a single pallet jack +/- an overhead bridge crane. Once in place, I don't imagine them moving.

Are their systems/materials that can handle larger masses? Are smaller tiles with more supports a sufficient solution?

Really only 4-5 heavy pieces of equipment. Only two above 1000 lbs. I think 1150 lbs max, but unclear how many points of support under those. I had thought of placing them on 4x4's so that they could be moved, if needed, in the future easily with a pallet jack. That would clearly spread out the loads over large contact area.
