I had a spiral staircase installed. The stairs were attached to a single round iron column. I installed a lally column underneath for support. However, I think for such temporary use you could probably use a beam standing upright. You could knock it into position or possibly support it with a floor jack.
I've lifted a couple of machines into position using lifting straps, a chain fall, and a heavy duty I screw in the joist above where it was going. I just left the I screws installed in case I need to move them again. I'm not too sure about using rope as it has a tendency to stretch and old rope decays over time. I don't know if 2x4s will be strong enough either. And the machines might tend to slide on them. I got lifting straps from HF. They did the job and were cheap enough:
