mrmattandmrchay, i used to work for express, and they installed a duplex in 1964, the top speed was 1000 ft per min but were governed down, that was fast for 60s.
This is a geared machine, the motor turns many many more times than the sheave that the ropes are attached to - so when you are turning the motor it is vastly geared down. Also, he is winding the lift in the upwards direction. This is easier as the counter weighs the same as the lift car plus about 40% load, which means if you were to remove the brake it would travel upwards naturally (with noone in it)
Why did someone dislike this?

I like how he was demonstrating the Otis safety system on a Kone lift!

there are no vids of the lifts in p.o. tower, after bombing in 1970, no public allowed in.

express made the best lifts in 60s and 70s, check out post office tower.

@express777100 Yes, those were Express as well. I did a search on YT but didn't find a vid.
