those flashing door open / close signals are irritating as fuck
but the rest of it (especially the motor room) is MIND BLOWING
They are for the visually impaired
A light bulb in a panel can act a small heater to keep the inside dry.
Love the bell @ 0:22! 😁
They could have modernized those 4 times over in the last 60 years and they would be no better off. That open contact relay stuff can last a really long time, instead of a computer with the correct software version to scan and bi-directionally control stuff all you need is your eyes and a rolled up newspaper.
love this, rare find and is DC . never usually get any old dc lifts anymore.
Wow, those are absolutely perfect. Nothing beats a well running DC gen-set lift, even getting rare in the states now they used to be everywhere.
In America most old lifts are DC. DC lifts always have a smooth and quick ride if cared well and last a long time! I hope this lift does not get modded!
DC lifts don't last as long as AC. Too many moving parts. And a lack of spare parts
Fantastic
Noice
You just gotta love old express lifts!
Ultra rare indeed. I like how smooth these are
DC lifts are known for being smooth
That lift is so posh and very quaint. No wonder it’s been maintained perfectly.
Wood innit
Why use a DC motor on it
Cause days before VFD this was the only way to have a perfect smooth leveling.
Before VVVF drives AC would only be capable of 2 (or if you're lucky, 3) speeds, which would cause quite the huge jerk on slowdown. That's already bad enough in a 1 m/s lift, but imagine going from 2.5 m/s to 0.3 m/s in just a few hundred milliseconds! DC motors can control speed much more finely, so that's what they used for high speeds.
