It like a walk through time watching your videos 😂😂 I’ve never seen such old equipment since I started in the 80s I remember when Otis bought express we the Otis engineers didn’t like it and be honest the company was never the same again
It's a well maintained basement traction machine, an interesting design of the floor relays/and floor selector. 400 VAC 3P is good less current draw on each phase than on lower voltage. Probably has four guide sheaves, offset from the cab and counterweight frame.
