Ich finde diese versenkten Türgriffe wunderschön. Ich habe einen 50er Jahre Werkzeugschrank in meiner Werkstatt mit den gleichen Griffen. Freue mich jedes Mal über dieses unvergleichliche *Klongk* beim Auf- und Zumachen.
Das stimmt, diese alten Türriegel machen wirklich Freude beim Bedienen. Und die Türen sind auch ordentlich stabil, die halten einiges aus. Ist heute leider auch nicht mehr so...
WOW But what an absolutely fantastic machine, I have never seen one with a dual engine with this model presented here, moreover a 3000 kg freight elevator with a speed of 1 m/s is not common at the time. The sound of the motor when starting is just AMAZING, it is identical to elevators with Aconic controllers (probably because there are the same start contactors). You have found a magnificent, truly awesome freight elevator :D
Indeed, this lift is kind of a league of it's own. The motor room is completely filled with this massive machine. The W60 gearbox is huge and the motors are too! Also this thing is really fast for a freight lift of that size and the motor sound is just epic.
@@TheLiftDragon Ob es auch eine W60 ist kann ich nicht mehr sagen aber in Hamburg gibt es einen Schindler Lastenaufzug mit über 14to Traglast 25m Förderhöhe bei 4:1 und die alten Haushahn SW3 sind min. genauso groß, bringen ohne Öl, Motor und Rahmen ca 1,5to auf die Waage
14 Tonnen bei 4:1 ist eine steile Ansage! Das muss eine rechte Maschine sein, ja. Wäre sicherlich auch höchst spannend, wenn man sich das mal anschauen könnte. In der Nähe von Bern kenne ich eine Anlage von Emch mit 9 Tonnen, die ist aber in 6:1. Auch etwas, was man nicht alle Tage sieht. Gebaut Anfang 90er, jedoch jetzt mit einer neuen MB95 Winde von Sassi.
Both sides of the cables are terminated on the one support framework in the shaft head that is exactly in the center of the shaft. The other framework carries two sheaves that guide the ropes coming up from the traction sheave along the shaft ceiling to the counterweight on the opposite side of the shaft.
Probably that elevator is so good and reliable to the point that it’s too good to replace with anything newer and anything that’s newer may also be more expensive to maintain and not as reliable! :)
This thing sure is still running like a charm and I hope it will stay like that. One has to keep in mind though that all the other lifts in this complex (2x group of 3, 2 single passenger, another freight but hydro) have all been modded already. However, I think that chance of this one still staying is pretty high because of the giant hoist machine - that would cost a fortune to replace.
@@TheLiftDragon Yup while a new lift that has the same speed and weight specs would be insanely expensive and cost a fortune to maintain because of it being under engineered and designed with a limited lifespan of only 5-20 years! However a company like Schindler could currently do something that could last up to 30 years! We also now luckily have better technologies for manufacturing so if any custom parts fail then they could be custom reproduced using 3D printing or laser machining for a reasonable price as long as they have the original design diagrams and schematics for those parts! :)
@@Techno-Universal If something would be done to this lift here, it would most likely be a mod with new controller, added inner doors and maybe an engine replacement. Yet I hope it doesn't happen. Maintenance here is done by Schindler, as is for most Schindler lifts in Switzerland. Also 3D printing is not a solution to all problems. Many of the parts needed for a lift have very specific structural requirements as they are load-bearing. 3D printing, depending on the method used, may produce parts that cannot handle stress equally well in each axis, this is a very complicated topic. The surface quality of 3D printed parts is a lot worse than that of machined parts. Forging can increase the strength of parts a lot, hence crucial parts like this drive shaft are best forged first, then turned on a lathe. It even must be periodically checked for micro cracks in oder for the lift to stay safe to operate. I have worked in CNC machining for years and there are reasons as to why all that is used on a lift is still made that way.
@@TheLiftDragon Yeah if the logic fails in that case they could probably just replace it with something like a 7700 series logic which is Schindler’s modern equivalent of their Miconic logic and that would probably also include a VF drive being installed though in that configuration it could still keep the lift running just as well or better than what it originally was! :)
@@Techno-Universal There is no the "7700 logic". That sounds like another term invented by a certain individual who has no clue about what Schindler really does. There are different types of Schindler Miconic controllers, high-rise applications would use a CO-TX. The controller for standard applications would be the CO-MX. CO-BX would be the motor room equivalent of the Bionic but we don't want that because it's the worst controller Schindler has ever made. Anyways, we wouldn't have any of that today as the new scalable controller SC1 can be used for everything. But I digress, none of that matters. If this lift were to be modded by Schindler, a generic BP408 controller in combination with a ZAdyn drive would most likely be the combination of choice. It is in general one of the best controllers out there and has all the features you would ever want. In case you don't know what controller I'm talking about - here's a good example of what it can do if set up properly: ua-cam.com/video/QVQ5EYR5J4I/v-deo.html
Really long drive shaft on that gearbox, how often do you have to do NDT on it to check for cracking, as i know that is an issue with the long shafts and the external plumb bearings.
Indeed, ultrasonic testing is carried out on these long shafts in regular intervals. If I remember correctly, this is done every five years. I'll check the maintenance log when I'm at this one or a similar lift again, then I can say for sure.
This lift is Huge! And the fact they are relay controlled add to the “Wow” of the lifts, also, why is the motor on the bottom, couldn’t they place it on the top and save some money on sheaves and extra ropes?
Indeed, this lift is a chonker and the machine is massive. Putting the motor room to the top would have required building an additional structure on top of the building, which was not needed with this solution. There is only the shaft head wich protruded a little bit out of the roof.
@@Avidiy Yes, it does. Every traction lift must have an overspeed governor. It is located in the shaft head and I've included a photo of it at 7:48. Also you can see it in motion at 8:47.
Starting from the lift car side: Look at 8:36. The cables are suspended from the framework aligned with the center of the shaft. They go down on the lift car, are deflected on the top (see photo at 7:41) and then go up to the framework again (continue watching at 8:36). There is 2 sheaves on the left side that deflect the cable down to the traction sheave at the motor room (see 9:10). Then the cables go up the whole length again in the very corner of the shaft (9:33 on the right side, camera is pointing the other way and the counterweight is now on the left), across to the other side over the framework that is slightly angled and down into the cage of the counterweight. They're deflected on the counterweight (photo t 7:46) and are then fixed on the very side of the central framework again (9:42).
Got it. From the top, to the car, to the top, to the motor at the bottom, to the top, to the counterweight, to the top. It's as though the motor had to be at the bottom because there wasn't room for it at the top.
This is exactly why one only performs such actions when it is certain that the lift is empty. Also these are not contactors, these are relays. They correspond to the call buttons in the lift and moving the lift through them is only possible if safety is present, therefore all doors must be closed. If anyone were to open a door I would instantly be notified through the occupied lamp in the relay rack. Furthermore it should go without saying that such actions may only be performed by trained personnel and after studying the diagrams.
Hab ich schon oft gesehen, Relaisanlagen mit MG5. Bei den ganz alten Anlagen wird die grosse Last ja durch die Umschaltapparate an den Bremsen geschaltet, das ist eigentlich sehr clever und man spart sich die grossen Schütze. Die Anlage hier ist aber schon neuer und hatte von Beginn an MG8 als Fahrschütze.
1m/s ist per se schon lange die Standardgeschiwndigkeit für die meisten Standardanlagen. Aber für einen Warenlift aus den 70ern ist das in der Tat recht schnell, denn die meisten ähnlichen Anlagen wurden damals nur mit 0.63m/s gebaut, teilweise sogar nur 0.5m/s. Gerade für eine Anlage mit dieser hohen Kapazität ist das eindrücklich, daher auch die riesige Antriebsmaschine.
hi sir how are you sir i am lift technician i have 15 years working experience in duha qatar i have worked for 13 years i want to apply a visa in your company
Etwas in die Jahre gekommener Aufzug! Gute Aufnahmen!
Danke. Die Anlage ist alt aber dafür auch standhaft. Ein heutiger Lift würde wohl kaum 50 Jahre halten...

I can watch the relays, motor, and specially the Schindler wheel for hours!
Does this loft have a safety governer?

Manually engaging contactors. What if a person was in the lift. He has no control if not informed.

Relativ schnell für einen Warenlift und das Baujahr.. nicht? 😂

hi sir how are you sir i am lift technician i have 15 years working experience in duha qatar i have worked for 13 years i want to apply a visa in your company
You best ask one of the big lift companies directly through their website.
