Ja sind echt hübsche Anlagen. War echt n guter Moment als ich da war, nicht viel los, da konnte ich schön alles dokumentieren. Der Dynatron S Sound ist toll, nur nerven halt einfach die Lüfter. Die würde ich heute auch abklemmen für die Aufnahme.
Oh great, you also filmed these elevators, the layout of the machinery is similar to that in the Bienne tower with only one of the elevators not being able to access the very last floor. I remember having also seen such an installation in Lausanne with only one elevator accessing the very top where the machinery is located. Nice video :D
Cool machine room! Someone forgot to remome the yellow hand wheel from the middle lift. It is only needed by moving the lift by hand and than to be removed from the motor. But looks nice though :-)
Thx! Indeed the hand wheel was left on here, probably forgot. If I remember correctly (these video sat around for some years) I tried putting it back on the wall where it belongs but it was stuck on pretty firmly, haha.
Cool smart leveling (I think) 5:22 that stopped a bit hard, but I bet that is because the lift car was empty and the counter wight was heavier than the lift car. 6:51 That was VERY cool to see! Also the Otis “Re-Gen” elevators that i have in my apartment work 24/7 with almost never stopping (except for when the doors cycle open and close) 7:06 This is my favorite lift in this motor room! I don’t know why manufacturers don’t make such cool things nower days, but why did they choose this kind of motor sticking out and warping to the top of the shaft and back down? 8:29
The Dynatron S drive system is pretty good at levelling. It could be called kind of intelligent, though in German we would just call this "direct levelling" (Direkteinfahrt). I actually would like to see this term adapted into English because it describes a lot better what's happening. The lift stops at the floor directly, with no creep travel. Dynatron S however is not "intelligent", it is a static system. The breaking distances are fixed and always the same and the closed loop control is responsible for stopping. Other old systems like Dynatron 2 or Kone TMS for example work the same. They just need a set distance to stop and it can't be changed. Now if some of the controller parameters, which are set through potentiometers, are not quite right, this harsh stop might occur, most likely through not enough gain. I also really like the setup with the rightmost lift travelling past the motor room, where you can see into the shaft from the motor room and vice versa. Nowadays you wouldn't find something like that indeed because everything is now standardized and cheap. These custom constructions are a lot nicer than your standard MRL but they'd also cost a lot more.
@@TheLiftDragon thanks for me to know this is great. I totally agree that you wouldn't find these nice and cool motors on the left. I meant to say that I LOVE this thing but is there a speaific reason that this is there. If not still I love it. Also aren't potentiometer which spin like 270° too in acurate, or they use trimmers
@@Avidiy Yes, it's these potentiometers that only rotate a bit less than a full revolution. There also are multiple dip switches which are used to set the nominal speed of the lift. These values are fixed and can be 1, 1.6 or 1.75m/s. There is another setting though for special velocities like 1.2m/s (common on mods from older lifts) but then the Dyn S needs special factory setup first for that. Anyways, the 7 potentiometers are for different parameters like traction, load compensation, holding amplification, braking amplifiaction and also intermediary speed amplification. The braking distance can not be changed with the potis because this is a closed ecosystem and the braking distances are always predetermined, depending on the nominal speed. For the 1m/s we have here it's 1.26m and for 1.6m/s it would be 2.36m. Nominal acceleration therefore is also fixed at 0.5m/s² for 1m/s and 0.68m/s² for 1.6.
Yeah there's some extra rope stuff and diverting going on in order to make this work. But a bottom drive is basically the same principle and we have a lot of those around here.
All these nice lifts you work on, and they all look so well maintained as well, and all in near perfect order.
We like to have things nice and clean in Switzerland. ^^
Top Service, sehr saubere Anlagen.
Dankesehr!
Die werde ich vielleicht auch mal filmen. Sehr schönen Motorsound!!!

Nice video :D
Yes indeed, the 2 old 2-speed Schindlers in Biel have a similar setup. I really like that because it's so unique and really rare. Thank you!
Sehr schöne Aufnahmen 👍
Dankesehr!
Very nice presentation! Subscribed!
Thank you, I really appreciate it!

Gut gemachte Aufnahmen! Video gefällt mir!

this is pretty epic
Yeah the arrangement here is pretty unique.

@@TheLiftDragon thanks that's a GREAT in-depth explanation!
thats a whole lot of ropes for the lift with the drive on the side
