Indeed, list installs in Switzerland are kept very clean. The pits surely are really clean now as these lifts have been fully replaced a few years ago, the footage is from 2020.
Nice lifts, I like the old ones. In the description you said (VFDs in an open loop configuration) you mean the motor without encoders? I didn't see any encoder and maybe I'm wrong but it's interesting performance for the VFD if it's true.
@TheLiftDragon Wow, this is a very interesting performance, I saw many open loop configurations but they creeping long distance before stopping at level like it's an AC2 motor but smoother.
Would also have loved to see that but sadly the original equipment is long gone already. I have other videos in my backlog though that show original Schindler relay equipment - and quite some on my channel already.
Werde schauen, ob ich mal dazu komme, es ist ja keine Eile geboten. Habe aktuell noch viele andere Anlagen, auf denen mein Fokus zum Dokumentieren liegt. Einige grössere und schnellere Sachen.
It's kinda hard to tell, especially since their popularity varies greatly depending on the country. In western Europe, Switzerland really was (and still is) the country where they're most common. Else they can be found a lot in some countries of the eastern block, like Croatia and Serbia. Innerdoorless lifts somehow emerged from the swing door lifts with scissor gates. I guess it was simply deemed more convenient to just have a perfectly flat plastered front shaft wall where nothing could get caught on rather than having a gate you need to manually open and close every time. Simply have a moving room where you open the door, walk in, ride, get out again. As for why they survived so long - I assume they are (or were) cheaper to install than lifts with automatic doors. In Switzerland they were the norm from the 40s till the 60s, with the fastest ones going up to about 1.75m/s. Around 1970, lifts with automatic doors became the norm for office buildings while the innerdoorless were still standard in most residential buildings. From ca 1980 on, passenger lifts were generally built with automatic doors, but innerdoorless freight lifts were still the most common thing until the early 90s, when swing doors were finally phased out. I'll actually post such a video very soon - a freight lift from the year 1990 that is innerdoorless and in original condition.
@ Oh. In the US sliding doors were basically the only type of doors from like the 1950s onwards. Swing doors are mostly found for handicap elevators here.
I can only record at 30 or 60 fps. Anyways, a change of framerate would not solve this problem as these displays run on 24VDC coming from a switching power supply. Their flickering/scrolling is independent from the 50Hz grid frequency.
@@TheLiftDragon Interesting. I always have problems with the frequencies of LEDs flickering colliding and causing that horrible effect on my camera. Usually recording at 50fps with 1/50th exposure is enough
@@mushroomcraft I know, that is a common problem with LEDs that have chap power supplies and run directly off mains voltage. But for lifts (as well as more complex LED setups) where the voltage is properly rectified first, this does not apply, at least not so easily. I have seen this flickering happen on different car position indicators in different speeds. I assume it has to do with the PWM frequency of the brightness control but still it's hard to fully figure.
@@TheLiftDragon it's always the PWM, along with being made worse by the rolling shutter. In the UK, the council estates have these energy saving LED lights in the corridors that all cameras hate. When the brightness changes because you triggered the PIR, it looks horrible on any camera. Manufacturers can't be bothered to use a higher PWM frequency, because most humans can't tell, but sometimes I can see the flickering with my own eyes, and it's so irritating. We live in a world where everything is getting cheaper, and we have to just deal with it.
Don’t know why I ended up watching this but don’t regret it
I've absolutely no idea as to how I got here but, good video none the less
Haha thx
These lift tours are pretty cool
Nice clean shaft and motor room, will bet the pit is almost spotless as well, with minimal dirt and dropped debris as well.

They are awesome!!
Gute Aufnahmen! Video gefällt mir!
Dankesehr!
Very nice!
WOW, really cool Mic SX logic, too bad they are replaced now.
SX is really cool indeed but they're also becoming more and more rare.
Relay logic...interesting!
There is no relay logic in sight here, this is a microprocessor controller.
@@TheLiftDragon Oh
Nice

Exactly, open loop refers to VFD without encoder.
@TheLiftDragon Wow, this is a very interesting performance, I saw many open loop configurations but they creeping long distance before stopping at level like it's an AC2 motor but smoother.
It would been cool to see the original motor and logic.
Would also have loved to see that but sadly the original equipment is long gone already. I have other videos in my backlog though that show original Schindler relay equipment - and quite some on my channel already.
❤😮lift121 la motorul de la❤
Sehr schade dass die 2022 komplett ersetzt wurden. Werdest du nochmals vorbeigehen und die ganz neuen filmen?
Werde schauen, ob ich mal dazu komme, es ist ja keine Eile geboten. Habe aktuell noch viele andere Anlagen, auf denen mein Fokus zum Dokumentieren liegt. Einige grössere und schnellere Sachen.
Sehr schön, nächstes mal mehr Vorzug wa. 😂
LG. German_Guy
Ps: war spaß. 😅
Danke dir!
Nun hier war Reservation ohnehin ein Gebäudezylinder. :P
How did you get in the elevator machine room? How did you get on top of the elevator a cool video?
I do have the necessary keys. However, I will not disclose the access procedure of the car top as these actions shall not be copied.
Why were swing doors and no inner doors so common for a while in continental Europe?

Please record your videos at 50fps, so the indicator doesn't do what it's doing at 0:37 onwards
