Sehr schöne Anlagen, ich hätte gestern einen 1989 janzhoff Aufzug in der Wartung mit Drehstrom Motor, der Sound war schon was besonderes, das hat man nicht oft. Einen guten Rutsch ins neue Jahr, ein Kollege aus dem schönen Ruhrgebiet
Mit Phasenanschnittregler nehme ich an? Ich mag diesen Sound auch sehr, immer wieder schön zu hören. Die Anlagen hier hatten schon von Beginn an Frequenzumrichter, diese klingen aber recht ungewohnt. Auch von meiner Seite ein Frohes Neues aus der Schweiz!
Dankesehr! So einem Klappsitz bin ich bisher gerade zwei Mal begegnet, beides in Deutschland. Ist extrem selten aber wenn der Kunde sowas wünscht, kann man das natürlich machen.
Old cars, showing wear, but well maintained. I would assume the bar above the hoist drum is there to keep the cables on, because some lift somewhere in the country had a cable jump off a sheave during an emergency stop, so the bar was added. Cables by the car top all fuzzy with dust, because nobody cleans that, nor the top of car either.
Indeed, these lifts still run very well for their age. They're true quality products. The bar above the sheave is a protection against the cables falling off, exactly. They are common on most lifts. And yes, that lift shafts here are very dusty. Maybe they haven't been cleaned after some renovations in the building or they just haven't really been cleaned at all. I'm used to more clean shafts / car tops overe here in Switzerland.
They are very smooth too, i do like the sound of the motors, it ain too loud either, also, the fact that they are 1 to 1 roped is quit simple, you just have the lift, and the counter wieght, no extra pulleys in/on the cab, they arent supper fast, but holding 1000 kg on a 1 to 1 roped setup is not easy, great video as always, love your channel
Indeed, these lifts run very smoothly and the sound from the motors is kinda calming. 1.6m/s is not very fast but it's adequate for the application here. 1:1 is the easiest solution for such a set of lifts here. There are even bigger ones, 1200kg, even 1600kg in 1:1. The highest capacity in 1:1 I have ever documented is 2800kg, but that lift is a another league. It can't be compared to anything ordinary, this lift is a unit. It will be presented here as well but that will take a while. I'm glad you like my content!
Mein opa hat für thyssen krupp aufzüge installiert, ich hab sogar noch ein paar anzeigen und knöpfe aus den aufzügen und auch noch netzteile für die steuerung und die wire wrapping werkzeuge die damals benutzt wurden, aber in dem system kam mir leider nichts bekannt vor.
Das klingt höchst interessant. Ich denke mal das Wrapping war für die ältere Generation der TCI, die ja auch dieses Steckkartensystem benutzt. Hinten an den Steckplätzen der Karten befinden sich Wrapping-Terminals für die Verbindungen zum Schrank und zu den anderen Karten, wenn ich das denn auf meinen Fotos richtig erkennen kann. Leider gibt es von diesen noch älteren Anlagen aus den 80ern nicht mehr viele, erst kürzlich wurde in Düsseldorf eine schöne Zweiergruppe ersetzt.
@@TheLiftDragon das stimmt denke ich, 80er kommt auch schon eher hin. Ich denke allerdings in ausland wird es noch welche geben, da mein opa früher auch auf montage im osten war.
Lift people... a question for you... Lift/elevator design companies are stuck in the old technology past. Why do even the most modern elevators still put a massive motor at the top of a building and dangle hundreds of meters of cable to pull a car up and down? Why not put the motor *on the car*? Then you could have options like variable speed, multiple cars per shaft, even the possibility for non-vertical travel. Also, bonus question... you've heard of passive magnetic induction yes? This is the technology used on those free-fall fairground rides that drop you from a height... they work because they have permanent magnets which interact with copper strips which are absolutely guaranteed to work to slow the riders down before impacting the ground. Why the heck isn't this technology used in elevators? Retrofitting is entirely possible; the result would be anxiety-free elevator rides - even in old elevators.
So many things wrong with this... the motor cant be on the cabin since it wpuld add massive weight meaning a bigger motpr in rezurn, higher operating speeds etc. The motors up top are speed controlled via pid, otherwise the elevator would overshoot its stops. Several cabins in one shaft wouldnt make the elevator faster, but rather slower, because the elevators cant pass eachother in the shaft basically creating traffic. The elevators going horizontal dont make sense since walking is very easy, the often isnt a lot of space to go horizontally in most buildings, it would make the design and maintenance a nightmare etc. There is a horizontal elevator in germany and its horrible. The last point... Every elevator in the world has emergency brakes. They arent inductive, but mechanical, they are braking with pads. Inductive brakes are heavier and would, again, add to motor size. In free fall towers they are only used because of repeatibility which isnt needed for emergency brakes. All in all nice ideas in theory but actually tested and turned out horrible.
@@indian.techsupport Your reply rather proves my point. A 450hp axial flux motor weigh in at less that 40kg. Hardly a 'massive weight'. Who said anything about horizontal travel? Elevators are nothing more than vertical tracked vehicles (like trains). Long gone are the days when train cars used to be pulled by cables and static engines. Like horizontal trains, tracks can have points (switches) and passing places. As for the use of friction brakes - I suspect all those who have died in falling elevators because the brakes failed would have welcomed by fail-safe idea - which only requires strips of light-weight copper or aluminium to be attached to the car while the permanent magnets are in the shaft.
@@mb-3faze well, since there would be no counterweight without cables the motor would need much more power. Also switches in an elevator shaft would use up as much space as several elevators and would still create traffic. And a 13 storie elevator shaft filled with magnets would cost immense amounts of money and would also degrade over time. As i said, if these things were practical elevator companies would build them because thats just how economy works. If an elevator company had better elevators than the "outdated" ones used today they would make huge amounts of money.
@@mb-3faze of course! Try spreading a bunch of bulky permanent magnets vertically along the guide rails and see how that works out for you. Not economical in the slightest. Not to mention the added weight on the rails that more than negates the supposed benefits of doing away with the "more traditional" steel ropes... In sum, huge machines, counterweights and thick steel ropes are used because they are a tested-and-true way of hoisting a platform full of people on top up and down a shaft.

I bet if he came back now he would say "what? no improvement over my basic design in over 100 years?".

nou deze installatie verdient een 10 , wat mooi zeg 👍
verder wens ik u en alle fans een goed en gezond 2024 .
Thank you very much, happy 2024 to you as well!
Tolle Lifte! Einen Klappsitz in der Kabine habe ich noch ie gesehen! Gutes Video

Can you give me the link for that video, I would sure want to see it, thanks!

Great motors there! It appears to have pre-doors (classic leveling)?
Yes, advanced door opening is enabled on these lifts.
Oh, I get it!

The motor(s) are so quiet
They indeed are.
