CN tower elevator machine rooms

I was on a Canadian Elevator Industry Educational Program (CEIEP) instructor training seminar in Toronto, when a friend from Otis asked if I would like to see the machine rooms for the elevators. The first part of the video is looking up from the bottom of the hoistway's The second is inside the machine rooms looking at the hoist machines, which are the second biggest hoist machines otis makes the biggest they make were made for the world trade towers. Otis had just replaced the armature (the turning part of the hoist machine) and it alone weighs 6000lbs. You could say the are the biggest now. The third part of the video is of the sway pendulum which detects building sway. If it makes contact at the bottom twice in 5 minutes it slows the elevators down from 1200 feet per minute to 500 feet per minute.

The CN Tower is a communications and observation tower in Downtown Toronto, Ontario, Canada. Standing 553.33 metres tall, it was completed in 1976, becoming the world's tallest free-standing structure and world's tallest tower at the time.
