5:40 wow, massive holes into the shaft

[@TheLiftDragon]

Indeed, these are huge. Great for filming but not really up to modern work safety standards. ^^

Besten Dank!

[@ElevatorExploration]

Here is a nice installation of four elevators. I notice that the motors have the particularity of having the rotor rotating around the stator which is not very common for high speed motors.

[@TheLiftDragon]

Indeed, these machines here are outrunners, where the rotor is built around the stator. Not very common but I really like that design.

[@REALABROOGAMING]

i love your video bro 😍😍

[@TheLiftDragon]

Thx!

[@Aufzug25]

du bist der erste der deutscher aufzug filmt und hast mehr abonnent als elevatorfan ich bin stolz auf dich

[@TheLiftDragon]

Ich filme zwar hauptsächlich Anlagen aus der Schweiz, aber ja, ich bin auch immer mal wieder in Deutschland unterwegs. Stimmt, jetzt wo dus sagst, ich hab ihn offenbar überholt. Es steckt ja auch ne Menge Arbeit in den Videos, das braucht viel Zeit und ist ein riesen Aufwand. Ich meinte, ich habe nach wie vor den einzige Kanal im deutschsprachigen Raum, der alle präsentierten Anlagen so detailliert zeigt. Da sieht man natürlich gerne, wenn sich die Leute dafür auch interessieren.

Double wrapped traction cables, I like that as it gives more grip.

[@TheLiftDragon]

Indeed, I like that too. Though one must also take into account that the traction sheaves here have circular grooves instead of trapezoidal ones like on most geared machines. Circular groves produce less traction than trapezoidal ones.

[@TheAeroflyGuy]

What are the big yellow things in the cages? And also, how does the double roping work?

[@TheLiftDragon]

You mean in the motors? The rotating part with the fins is the rotor of the motor. These motors are so-called outrunners, where the rotor sits around the stator. On most motors it's the other way round, where the rotating part is inside and only visible through a shaft sticking out of the casing. Double roping means that the ropes travel over the traction sheave twice. This increases the wrap angle around the traction sheave and therefore prevents rope slip. At 4:43 you can somewhat see how it works. There are 6 ropes on these lifts. The ropes come up from the lift car, go over the traction sheave, which is basically the motor, down to the diverting sheave behind the machine, come up from the diverting sheave again, go around the traction sheave once again, to the diverting sheave one last time and then down to the counterweight. Because of that, you can count 12 ropes on the traction sheave, because every rope goes over twice. When you look at it from the front, you can see the 6 ropes coming up from the lift car and you can see the same 6 ropes coming from the diverting sheave at the back to make the second wrap. Hope that explains how it works.

@@TheLiftDragon Thank you for such a detailed explanation! I'm very interested in lifts as I work at the Auckland Sky Tower, New Zealand. I'm NOT a lift technician there, but, while being a Host for all the visitors to the observation decks, my passion has lead me to see/learn about all the lift machinery there from the technicians. We have three KONE MX100 lifts (A,B,C) with glass floor panels for the public to see down, and glass doors to see the view going up. We also have a KONE Dual Motor MX100 (Lift D) with UltraRope for our service lift. The technical specifications in my understanding are: Lifts A, B, C / Lift D KONE Re-Generate™800 / KONE Long travel ReGenerate™800 Manufacturer: Schindler, 1997 Modernised: KONE, 2015 Type: Traction, 1:1 Roping with Compensation Cables Capacity: 28 pax / 32 pax Travel Height: 200m / 225m Floors Traveled: 53 / 60 Floors Served: 1, 7, 45, 50, 51, 52, 53 / 1, 4, 7, 10, 14, 18, 22, 26, 30, 34, 38, 42, 44-60 Speed: 5.0 m/s - with reductions during building sway/high wind.

[@jbsimmons54]

First time I have _not_ seen floor buttons _inside_ an elevator!

[@TheLiftDragon]

This is actually more common than you might think. Nowadays, it is very common in big office buildings. On larger groups of lifts with many floors, this system can dispatch the lifts much more efficiently than a conventional up/down call system. It also has benefits if not all lifts of the group serve all floors. If you want to go to the basement for example, but only one lift of the group goes there, it will send you this very lift. With a conventional system you would just have to hope to get the right one.

[@mushroomcraft]

Touch screen destination dispatch in 2006??? Ok looking at it again, the refresh rate of the screens is quite bad, so it makes sense. Very futuristic for the time though! Really weird that there is a room that the cables pass through and that the governor is kept in. Would make more sense to make the shaft higher instead. Also that counter weight is very thicc!

[@TheLiftDragon]

Yes indeed, they are original from 2006. The lifts were built with destination dispatch from the beginning and the displays run on some super old embedded Windows.

[@folk.]

from where does the elevator car gets power and send signal? From a rail on the walls?

[@folk.]

Oh I found out. kzbin.info/www/bejne/bJyWpatqosuCn9Usi=ale9Szonyn864bFn&t=246 Flat cables

[@TheLiftDragon]

Exactly, there's always a travelling cable hanging below that connects to the shaft wall.

[@user-3580-t6w]

Very nice elevator, i have finded maybe the tallest ones with twin cabin, those are goes up to 6 - 8 m/s and they are located in federation tower, there are like 50 elevators there, in mine apartment complex i having 16 2008 kone minispace with speed around between 2 m/s up to 4 m/s and they going up to 47 floors those are equipped with mx 18

[@TheLiftDragon]

Those are some really impressive numbers! One does usually not see such fast things everyday. Though it also has to be said that especially super tall residential towers aren't really a thing around here.

[@Swiss_Vator]

Die Aufzügen sind ja echt schnell!!!

[@TheLiftDragon]

Jap, die Anlagen hier sind wirklich schnell unterwegs. Findet man in der Schweiz leider nicht zu oft.

[@Swiss_Vator]

@@TheLiftDragon Ja die schnellsten sind glaube ich die im CityWest Hotel in Chur. Bis jetzt hab ich noch keine schnellere gesehen.

[@TheLiftDragon]

@@Swiss_Vator Wir haben in der Schweiz viele schnellere Anlagen, man muss nur wissen wo. 2.5m/s habe ich jetzt schon zig mal gesehen,d as ist für mich auch nicht mehr so besonders. Wir haben einige Installationen mit 3.5m/s in der Schweiz. Der Prime Tower müsste ausm Hinterkopf iwie 4 oder 5 m/s haben, Die Anlagen aufm Jungfraujoch haben 6.3 und in den Roche Türmen gibt es 7. Aber letzter kann man natürlich nicht filmen. Das schnellste, was ich bisher dokumentieren konnte, ist 6.3m/s, aber nicht in der Schweiz. Hierzulande hab ich bisher 3.5m/s gefilmt, zwei komplett verschiedene Anlagen sogar. Im Gegensatz zu Deutschland haben wir halt viel später angefangen, hohe Bürogebäude zu bauen, deswegen ist es bei uns auch schwieriger mit hohen, schnellen Anlagen. Wohngebäude haben generell halt langsamere Sachen drin. Schindler 5500 mit 2.5m/s z.B. gibts aber echt überall, sogar einige mit 3m/s. Aber das ist halt alles dasselbe. Es ist zwar schnell, aber irgendwie doch langweilig.

[@Avidiy]

Those are some BIG motors, yes Otis made bigger motors, but these are still big nonetheless, the brakes are quiet too. also what technology do these motors use Permanent Magnet VVVF etc. It would be cool if they had intelligent leveling, as I see they take rather long to level for such a fast lift

[@Avidiy]

Great to see some gearless with 1:1, guess that's why they are big…

[@Avidiy]

Also what amazes me about these are there is SO much tourqe, they are gearless, and they can spin rather fast and SUPER slow, for the leveling!

[@TheLiftDragon]

These are big machines but they're not the biggest by TKE. It's not only Otis who made bigger things, TKE themselves have too. So has Schindler as well and don't forget the Kone MX100. The DAB450L machines are AC gearless but unlike most machines, they're not synchronous. Asynchronous gearless machiens like this are a bit of a rarity. Leveling on these is completely fine. It's not fully direct but due to advanced door opening the doors start to open as soon as the leveling speed is reached, so this doesn't have a significant impact on transport efficiency.

[@TheLiftDragon]

These are 60s lifts after all and back then high speed was basically always 1:1 except for maybe really high capacity beds lifts in hospitals.

[@Avidiy]

@@TheLiftDragon yes Schindler 7000, and Kond MX100 all are big machines and TKE themselves make huge machines too, but these are still bigger than usual nowadays, I love to see Classic Levling/Pre Doors, missed that in the video. I didn't know that which type they used, so knowing that Asynchronous is rare is great too

[@drphipshiolidge]

Do you get permission from the buildings owners to make these videos and access the motor rooms??

[@Aufzug25]

kannst du extra nach mannheim fahren und den aufzug bei collini center filmen mit steuerung und schacht? es hat 30 stockwerken TKE Aufzug

[@TheLiftDragon]

Mannheim wäre am Weg, wenn ich wieder weiter nördlich nach Deutschland fahre. Extra nur nach Mannheim fahre ich sicher nicht. Vielleicht ergibt sich mal was, wenn ich auf Durchreise bin, aber das kann ich nicht garantieren. Die Anlagen voll zu dokumentieren ist nämlich immer ein riesen Aufwand.

[@igorangelkovski3760]

I'd love to have been able to see these lifts/motor room in their original form do you know more details about them before they got modernized? Were they also running as a set of 4?

[@TheLiftDragon]

Me too, an original set of high-speed lifts from 1960 would be an insane relic of the time. I know of some such installs from Otis that still exist in the US, but all the European companies like Kone, Schindler and TKE (back then Rheinstahl, as mentioned in the video) also had their own high-speed drive systems. But due to the rarity of older tall buildings in Europe in general, these installs are now super rare and mostly modernised. What can be said is that the lifts here must have originally been DC gearless. That's the only way to reach the speed they have, assuming they were this fast (or at least >=2.5m/s) from the beginning. It is very likely that the MG sets for the DC voltage were placed on the low floor below the the motors, where the governors are. Controllers must have been relay, cause to my knowledge, Schindler and Schlieren were the only ones installing advanced transistor technology at that time. A group of 4 lifts is probably the most likely scenario here, but that I can't tell. Could also have been 2 groups of 2 but that's just a guess. 2006 is almost 20 years ago now and trying to figure out what was before then is really hard. In hindsight I should have had a closer look into all the documentation on site, maybe there would have been some more information. But especially in Germany this is always a gamble. Sometimes there's a huge amount of paperwork containing everything one could wish for, including drawings of the shaft and motor room. And on other occasions there is, well, nothing but a few schematics.

[@igorangelkovski3760]

I fully understand, thanks a lot for your time trying to address my question In my country (Macedonia, part of former Yugoslavia) there were mid to high-rise lifts made under license from Schindler and Rheinshtall with various types of drives, but they have been all modernised since many have been beyond repair, mostly due to poor maintenance. I'm refering to lifts made up until the early 1990s. Some simpler 2 speed drives still live on in apartment buildings to this day. I can't wrap my head around the fact that 2006 is almost 20 years ago😅 Time flies so fast

[@TheLiftDragon]

@@igorangelkovski3760 You're welcome! That's interesting to here. I know of Daka-Schindler, so lifts built by Daka under license of Schindler. But it's the same story there with only very few remaining that have the faster, more advanced thyristor drives. Also yes, time is just flying by like crazy. And then I'm trying to somehow capture the old relics of lift engineering that are still around before they're gone, which is getting more and more difficult over time.

5 min 30 ils sont bizarre les câbles de traction, déjà ils vibrent beaucoup comme si il y avait une différence de tension et en plus ils sont recouvert d'un floconage blanc comme de l'amiante ??? en plus il y a un bruit toc toc toc comme un corbeau de régulateur de vitesse qui frotte. Les machines sont sales, idem pour le toit de cabine pas fier de montrer des équipements dans cet état En plus tu filmes sur le toit de la cabine en grande vitesse en montée, comme si les ascenseurs ne se retrouvent jamais en fin de course haut dans le plafond, pas très clean au niveau sécurité.
