Clip from Understanding Skyscrapers - some old Otis lifts with relays/selectors

Here is a clip from a series called "understanding...." that was on the Discovery channel.
The clips are from the program, focusing on the John Hancock Tower in the US. It shows the motor room with the classic otis floor selector and relays.

Would be great to walk around that relay motor room with Dave (see 2:52 onwards). He commented to the camera crew..."I don't know how engrossed you want to get with this...". I would travel all the way from the UK to have an engrossed tour with him! Very interesting to see how the logic of 'which lift responds to which calls' worked without using computers and micro processors.

This was filmed in 1999. The narrator comments on a building being designed as the "newest, tallest building in the world at 110 floors". This was obviously before the Burj Dubai was in existance! Bet those relay motor rooms have been updated now as well!

[mrmattandmrchay]

Yes I know, it's a shame that he closed his second account. Not many people posting stuff on motor rooms now.

@jorologo kind of reminds me of simpler times - all those wires and relays, if one day someone found a disused elevator with everything intact and made it work again...

Great video, very interesting

@jorologo yeah, I miss the old relay and generator jobs - maybe it's just nostalgia, a bit like vinyl LPs - more hassle, but more character as well

[mas90009]

@mrmattandmrchay you do :-)

That Old Lift Mechanic is right when he say that relay logic and processor logic are a different ball game. I,ve been exposed to both types of systems. Nowadays I deal more with Microprocessors but it is always good to go back to the old relay jobs. I just love watching young apprentices jaws dropping when they see older jobs. Its Like comparing Logarithum tables with an electronic calculator.
