Hello,
I am involved in the programming stage of renovating a closed church to re-purpose it as an auditorium/lecture hall. I am trying to find an engineered product that will allow an electric projection screen case to be concealed behind an arch around 30' high and drop the entire case down to a usable height for viewing.
Preferably I'd like a packaged product, UL listed so I can provide cut sheets etc. to the architect and GC. All I've come across so far is a system made by screenite, who seem to be an Italian company. Not sure if they distribute in the US or if their product would be a match for my application.
Thanks!

Jeff,
Have you thought about using a cyclorama or scrim type material kept under some tension? I know it doesn't address the mechanical challenge(s), but it might make it more affordable and repeatable.

Check out the viaWinch and viaLift from iWeiss and similar units from JR Clancy. Probably could be factory-built for a screen and not lighting fixtures as shown. A phone call or email to either should get you more detailed solutions to your need. Both are long-time theatrical rigging manufacturers. Any good theatrical rigging installer like SECOA or Sapsis can probably suggest multiple solutions too. In any case, it won't be cheap. Just Google "theatrical rigging".

If the screen does not have to move during the event, a manual worm-gear winch might work.

Electronic Theater Controls also has a winch product. I happen to think it is better than many things on the market, but ymmv. I like that as long as the vertical load can be supported, it has its own horizontal stabilization built in.

If I were you I would substitute my own Fabric in one of these: http://www.motorizedsolution.com/products/motorized-window-treatments?gclid=CKKZtqSqlboCFVNo7AodFzQA4w

Looks pretty close to what I had in mind. I wasn't thinking recessed case because the ceiling is arched. The idea is hide it all behind the arch. However, this is all made much more complicated by the fact the screen case won't fit within the constraints anyway without extensive work to the ceiling. We have not explored the feasibility of that yet but the Stewart product looks like something the builder could plan around.
Thanks a lot!
