You're still losing way less height than the same capacity jib because the beams are lighter for a given capacity/area.That’s the issue with bridge cranes you need so much ceiling height to make them useful. The bridge crane next door needed 24’ sidewalls to get 22’ under the hook.
My beams came in yesterday so maybe once Christmas is over I’ll start burning that bitch together.
If your fixed beams are in the same direction as the next floor's joists then you only lose the height of the traveler, trolley and hoist.
