we are trying to do a 30' Revolve for our fall show at my university. I am starting to work on automation for this show. We want to use an existing motor we have to drive our revolve. we have been using the mechanical design for the stage book but we are having trouble figuring out horsepower and torque needed to turn it. We would like to to do a direct drive if at all possible if not we are looking for a way to use chain as to prevent slipping and a way to attach facing. We plan on building with casters wheels up on the deck to support the revolve and to level our casters on an non level stage. Our specs are as follows Winsmith 924 speed Reducer 1750 RPM 960 Torque in.-lbs. The HP says 2.08??? not sure if this is correct We need to do a 120 degree turn only one way but if possible 360. We are estimating having about 4000 lbs for the revolve (structure, set, and actors). Any advice would be very helpful.
