This group of lifts is installed in a tall residential building. They were installed by Flohr-Otis in 1971 when the building was constructed. They were very well specced for the height with a speed of 2.5m/s and a DC drive. In the late 1990s they were modernised with new Otis MCS321M controllers and 18ATF geared traction machines. The lifts run very efficiently with good acceleration/deceleration and advanced door opening. The lift cars themselves including the door drives as well as the counterweight and other mechanical installations in the shaft remain original. Even the iconic Otis flyball governors have been kept.
Also found in this building is a service lift, which is still in the original state from 1971! A video can be found here: • EPIC 70s High-Rise DC ...

Hi! I visited my first real elevator machine
A room of Otis Pre Lexan elevators modernized by Otis in 2003 with extremely rare gearless motors from the 70’s
That sounds interesting!
That is some fine photography work, my friend......with out all the "amazing exclamations"
Thank you!
unpopular opinion: your videos are nothing short of ASMR :D
Hahaha Thx! XD
Gute Aufnahmen! Die Motoren haben mich beeindruckt.
Dankesehr!
Nice modernization of these elevators, the motors run really fast for geared winches, this is not common.
thanks for this video upload :D
Indeed, this mod is really well done and I'd say the MCS321 (RCB 2) is the best modern control system Otis has ever built. Much better than the newer TCBC or GECB for the Gen2s.
Nice door operator!🤩
Indeed, I'm glad they're still original.
Very quiet running in that shaft.
Indeed, they run very smoothly.
Hi ich bins Swiss Vator das hier ist mein 2ten YT Kanal
cok makasih ilmunya
Wieder mal ein sehr gutes und Interresantes Video👍.
Für Getriebemotoren laufen die ja sehr schnell, hatten diese Aufzüge davor die Otis Black Buttons?
Dankesehr! Ja, die Anlagen hier sind wirklich die Obergrenze für Getriebemaschinen. Habe bisher nichts schnelleres gesehen als 2.5m/s.
Den Originalzustand der Anlagen hier kann man noch am Servicelift sehen, Link zum Video davon ist in der Videobeschreibung. Das Interieur wird bei der Gruppe hier natürlich auch damals schon schöner gewesen sein als beim Servicelift, die Knöpfe müssten aber dieselben gewesen sein.
a question, how do you get acces to all these motor rooms in switzerland? are you a elevator technician?
What is that stain on the wall behind machine #1? It looks as though something went wrong which caused dirty oil to get flung out and sprayed onto the wall. Somebody probably had a bad day dealing with the aftermath, but I imagine it being an interesting story.
Indeed that is possible, looks like oil stains from the gearbox oil. However, I don't know anything about how or when that happened. By the looks of it the stains are very old, they could have happened years or even decades ago.
Any one of those driven pulleys is holding up the weight of the car, the load, the counterweight, and the cables, I think.
Half of it exactly, as the lifts are in 2:1. The other half rests on the motor frame.
@@TheLiftDragon Good point, only half. So, approximately the weight of the car. Anyway, that requires some pretty good bearings. And of course, the diameter and material of the axle have to be chosen properly to meet the requirements.
Helló! Where are the New videos?
Hello!
I've been on a break from RUclips for several months now, but within the next weeks I will try to get back to my usual schedule of uploading. I've still filmed a lot during this time, so there sure will be videos.
Balls
But why are they spinning?
