Old Otis Traction passenger elevator @ the Science A building at the University of Calgary

This old Otis Traction Elevator has manual operated exterior sliding doors, but the inside doors are partially assisted with power. Watch how they work and yes I am aware that these are common. This building was locked up a couple of days ago when I had hoped to see this elevator and to see if it was still original. Sure enough, it was still original. Older University's often hold lots of old treasures of elevators.

Before the advent of microprocessor, computer control/programming, elevators

were controlled by banks of relays in the machine room. If the hoist motor was

DC there would be an M-G (motor generator) with start run control relays,

changes AC-DC to power the controller board, and hoist motor.

i rode on one similar one day, and I saw something like this on mythbusters 'elevator of death'. How do those old elevators stop at the right floor with no computer?

There is, or was, something kinda' like this at Burbank Hospital next town over. Hopefully, they never tore down the old part of the building like they planned. Ultimatley, I don't think they did. Don't remember if it's public use or not. I don't remember stipulations on it.
