The Sanfilippo Wurlitzer lift coming down into the safety cage on the lower level, as seen from below. The large screw is a good four inches in diameter, and very greasy. Two iron girders stand vertical on the sides supporting the platform and console (and organist) as it descends (or rises). While it does make noise, during concerts you generally don't hear this over the music.
