This lift is situated in a 70s residential Tower in Berne. The building was constructed in the late 1960s and has three staircases, each containing an identical lift. The lifts only serve every second floor and the stops are located between two floors. In order to access the apartments, one has to walk either up or down the stairs by half a floor. The original lifts in this building were innerdoorless which can be recognised by the original door frames that are still visible from inside the shaft. also the front wall of the shaft was tiled as flat walls are a requirement for innerdoorless lifts. The tiles have been removed from the shaft walls upon replacement of the lift. Only a very small portion of tiles has been left at the very top of the shaft.
The shaft has a very unusual form factor. It is wide and shallow, forcing the new replacement lift to have a special chassis construction in order to fit in. The arrangement of counterweight and lift car in the shaft is original, the rails still use the original mounting brackets.
The lifts in this building had to be replaced as due to fire regulations in Berne, a fireman's lift is required for buildings taller than 35 meters. Therefore this lift was constructed for use as a fireman's lift, featuring an emergency escape hatch and a ladder inside the car. A second ladder is attached outside the car, allowing the firemen to climb up to the next shaft door and exit in case the lift breaks down. The lift is also equipped with an intercom between motor room, lift car and ground floor, enabling communication in case of an event.

Danke. Genau, diese Anlage ist sehr ähnlich wie der Feuerwehrlift bei euch, einfach halt im "Querformat" anstatt längs, bedingt duch die ungewöhnliche Form des Schachts.
That is a nice looking compact geared drive machine.

Sassi machines are not bad but I'm uncertain about how long they last. They also claim to be filled with lifetime lubrication, which is something that does simply not exist in the world of heavy machinery unless you don't expect the product to last very long.

@@TheLiftDragon Yes, I watched this video and I liked it but it's a bit strange for me to see 1:1 gearless because I only dealt with 2:1 gearless! Are they designed to be 1:1 or you can convert the 2:1 to 1:1? (maybe it's a naïve question but I don't know😅)

@@Moiraqi817 Gearless machines in general can be used with any roping factor. I have seen 1:1, 2:1 and 4:1 as well. There are also various older Schindlers in 1:1 configuration and top drive that have been modded with ZATop. I will publish a KZread Short on such lifts soon. In general the roping factor will stay the same as original because else the lift car, sheaves and holes would have to be modified.
Simple but it does the job. I had seen an elevator replaced by EMCH also with a metal cabin and a hatch above in a tower near Bienne. I did not understand why a replacement because the old one had already been modernized. In fact, I did not know that in Bern the standards had changed for lifts over 35 meters.

Indeed, it is not really special but it works well for what it's supposed to do. I don't know what the regulations in Biel are like. Now after you've mentioned it: The Emch MRL lifts you and I filmed in the very tall tower block have no fireman's lift and they were installed in 2017. Really strange.
Do you know the official year of discontinuation of the OTIS 2000 series, as the 2000 h and E brochures were still up on the Finnish website until around 2015 if I remember correctly.

The Elevator Wiki states 2007 as year of discontinuation, which I say seems realistic. Information from that source should always be handled with extra care as a lot on there is wrong - especially from the technical side. So this should be taken with a grain of salt.

@@veke1069 As I said the information there is not always correct. I imagine the discontinuation date to be different for different countries. Here in Switzerland the change from 2000 to Gen2 happened several years eralier already, with Gen2s from the year 2003 known to me but maybe ther are even older ones.
Do you also write in German or only in English? Question because I would like to say something about the video

@@TheLiftDragon okay hatte ich übersehen. Arbeite seit 1998 im CNC Bereich und kenne solche Drehgeber Kupplungen ebenfalls. Aufzüge finde ich faszinierend nur habe ich Höhenangst und würde nie auf dem Fahrkorb mitfahren. Mich interessiert die Ablaufsteuerung und die verschiedenen Arten. Es gibt hier ein Video vom world Trade Center Aufzug (alte Filmaufnahmen von der Inbetriebnahme) - angeblich sind dieses Otis Motoren die größten gewesen. Scheinen Gleichstrom Motore gewesen zu sein. Für viel Drehmoment nahm man früher große Gleichstrom Motoren mit hohen Ankerströmen. Zumindest weiß ich das so aus meiner Praxis. Danke fürs antworten 👍
