This epic group of three lifts is located in a residential building in Berne. The building is very interesting from an architectural point of view as it contains maisonette apartments. The layout though is rather uncommon. The maisonettes consist of a smaller floor that is located on the same floor as the access corridor going through the long axis of the building. the entrances to the maisonettes are on the left and right of the said corridor. Now comes the twisting part: The maisonettes on one side of the corridor occupy the floor above, the ones on the other sides occupy the floor below. This helps in understanding the spacing of the floors served by the lifts: Maisonettes on floor 2 go down to 1 and 3. Maisonettes on floor 5 go to 6 and 4. Floor 7 is a separate floor with storage rooms and no apartments. Maisonettes on floor 9 go to 8 and 10. 12 goes to 10 and 13 and so on. The floor A (= 20, A stands for attika) leads directly to the roof. The smaller back part of the building contains 2 small apartments per floor where the top most ones are located on floor 20. The small apartments that are not located one one of the floors served by the lifts can only be accessed by the stairs.
The Lifts are still original from the construction of the building in the early 1970s. They were built by Schindler with R-series fixtures and must originally have had either a relay controller or an Aconic transistor controller. The controllers were replaced by a triplex Miconic B system in 1993. The motors were kept original since they're compatible with the Dynatron 2 drive system. The whole drive train was replaced on lifts A and B in 2015 with new Schindler W250 winches and a Variodyn mod, so the Mic B controller could still be used. During this time, the W57 of Lift C was the only original Dynatron 2 Machine still in operation. Especially noticeable in the lift car was the loud bang that occurred when switching from SH1 to SH2 when travelling multiple floors.
But everything good must come to an end. In summer of 2021 the winch of lift C was also replaced with a Variodyn mod. Since Schindler no longer produces the W250 winches, a Sassi MF84 was bought and installed. It would have been really nice to find a gearless ZATop SM250 engine here but sadly this was not the chosen option.

Der Dynatron 2, meine absoluter favorit! Sehr schön das in 2022 noch immer etwas excistiert!

Ja in der Tat, ich hatte Glück es noch zu filmen. Jetzt ist es ja leider durch die Sassi MF84 ersetzt worden (siehe Ende vom Video).

[@joris3842]

@@TheLiftDragon Ja, der Sassi habe ich erst Heute gesehen... Gestern nur das wichrigste Teil der Video gesehen, die Dynatron. Schade dass sie weg ist, doch schön dass sie 50 Jahre im Bertieb gewesen ist! Nach der beendiging vom Getriebemaschienenbau von Schindler werder leider nur Sassi Maschienen installiert oder Getriebelos.

@@joris3842 Ja, das ist leider so. Ich hätte eine PMS420 oder Ziel-Abegg interessant gefunden, müsste mit der Variodyn ja möglich sein. Aber Sassi war wohl billiger. Zum Glück kenne ich noch ein paar Mic B+ Dynatron 2 Anlagen, aber die fahren alle leider nur 1.6m/s. Mit 1.75 gibt es aber noch eine Schlieren Monotron, die ich komplett dokumentiert habe.

Thank you so much for this wonderful video :D It's amazing I didn't know that Schindler were making their w250 winches still in 2015 I thought they hadn't been making them since ~2004. The only dynatron was very lucky to have been preserved until then, but its fate quickly caught up with it. What a pity on the one hand especially by what replaces it now, if at least Schindler would still have installed a W250, but no. We notice that the elevators are repaired randomly because in the cabin the buttons are changed whereas on the floors no and moreover, two cabins out of three have new doors as well as new operators without counting the replacement of the last dynatron well after the two others.

Thank you for this comment, I'm glad you like it! Yes there are indeed some sad stories told here with Schindler stopping the manufacturing of their own geared machines. But at least the Mic B were all preserved with this upgrade, so we are really lucky to still have them. The car panels seem to all have been replaced in one go but I don't know when exactly that was. From what I know the D-series fixtures did not yet exist in 1993 so it must have happened some time later. There is a simple story for the door drives. When I first came here in early 2021, only lift B had a new door drive, the other two were still old QKS 8. On the 2nd visit after the Dynatron replacement, all of the other door drives were also replaced. The one from the lift where the drive has been replaced as well as the one in lift A.

@@TheLiftDragon Mhm I see, thank you for these details ;D

So the third lift now has a Sassi motor, but wonder what's your say about them compared to other generic motors such as Sicor, Ziehl-Abegg etc. And I guess over in Europe you don't get American generic motors like Nidec-Imperial Electric or Hollister-Whitney?

OMG this lift is very fast

[@TheLiftDragon]

It indeed is, though I have filmed even faster ones.
