If you want to raise and lower a 16x4 platform about 8 feet, with an actor standing still in the middle of it, and if the circumstances would probably allow you to use either winches or hydraulic lifts, which would be better, from both a safety and a cost perspective?
With winches & cables it'd take either getting heavy stuff up on the grid (not very realistic) or running wire rope up the upstage wall, across the grid, and back down to the platform. I don't like that because it creates too many potential failure points.
So I'm thinlkng hydraulic lifts, mechanisms hidden in the stairways, platform brought in from above using the fly system. But I don't see a quick and safe way to attach the platform to (and afterwards detach it from) the lifts hidden in the stairs. Anybody know how to do that?
I'm attaching a NOT to scale sketch. The stairs on either end come in from the wings. The platform would be built on a steel frame, and could incorporate whatever might be needed to allow a quick connection to the lifts.
