Yes the london version of Joseph used a 3 ringed turntable, I saw it in canada and they got rid of it and instead, the objects just came out on a conveyar belt from under the steps/choir seating and off the other side, rather than through doors at the back.
Did the one in Woman in WHite on broadway squeak as much as the london one (it was terrible in london)
Lion King also uses a turn table of sorts, espicially in the touring version
