Thanks Doppelmayr! It's great to see you guys here. We appreciate the kind words very much.

Doppelmayr Seilbahnen It's much more unique than anything you guys build nowadays will ever be. (Cough) Old ropeways have character. (Cough) So do model ropeways.

@@TheTimmy376 It's never great to have Doppelmayr existing any more unless if they go back to building their 1960's/70's/80's/90's systems again. D-Lines are fucking ugly, mainstream, digitalized, invasive and un-alpine lifts and Uni-G's are fucking boring. I do agree that some Uni-G's integrate well into the mountain, but a D-Line? PAH!!!!

I can respect your admiration of classic lifts. Beauty, of course, is in the eye of the beholder - nevertheless I don't think it's fair to categorically dismiss modern Doppelmayr lifts in the way that you describe. Many such lifts demonstrate very impressive specifications and features, even if you don't agree with some engineering and technology decisions. This indeed affords Doppelmayr a definite raison d'etre in today's market. Also, let's please keep this comment section civil.

@@TheTimmy376 Maybe I am being a bit angry yes but after how many beautiful and mechanically different ropeways have been destroyed, all for ropeways that are mechanically the same? Grrrrrrrrrr... but in all seriousness Modern D-Lines ARE rammed with tech and are digitalized and they are too city-like, and in my opinion, don't integrate well into the mountain at all. Some D-Lines have stuff like speakers in the cabins, occupancy sensors, AURO(Autonomous Ropeway Operation), heated seats(which have now become a requirement), and other un-alpine tech rammed into them which makes them much more city-like and less alpine, along with their ugly city-like appearance. And their huge capacity does nothing more than bring on economic wars as ski resorts are often economically forced to replace their wonderful old lifts with horrible modern D-Line or 10-passenger gondola lifts/6-8 passenger detachable chairlifts as they make more money more quickly than do the jewellry from the 20th century. Capacity expansion causes nothing but suffering and chaos. It's excessive redevelopment, it gives people stupid reasons to complain just because the older lifts don't have the useless things that a modern one does, it makes the nostalgic people and enthusiasts unhappy and the way the modern lifts are architectured is disgraceful. And all the digital tech put in the modern lifts totally takes away the feeling of being in an alpine as well. And then there's obviously mechanical variety which modern lifts have none of and old lifts do and that in my belief is infinitely more important than modern advantage and higher capacity. The modernization is excessive enough that the mountains have become some sort of playground for Doppelmayr and the ropeway authorities, destroying these, destroying those, replacing them all with boring identical ugly mainstream lifts... Pfft. Ropeways will literally never be interesting if they are all the same and that's how Doppelmayr wants it to be. I intend to take action against the modernization in the future as mechanical variety and alpine appearance matters. Not mainstream crap that isn't even special any more and is just hideous in my opinion. Edit: With regards to Uni-G lifts, they are boring, REALLY boring and quite hateable to be honest. But unlike the D-Line they have no tech or modern standards in them and they integrate more nicely into the mountain than will ever a D-Line or some digital city-like scrap heap such as that built in the D-Line Era...

Thanks, glad you like it!

Thanks!

Thanks a lot!

Thanks!

Thanks!

Danke vielmals!

Danke schön!

Thanks very much!

Danke!

Danke für dein Kompliment. Bestimmt wurde viel Arbeit in iterative Design- und 3D-Druckzyklen gesteckt. Ich bin auch sehr gespannt auf dein Projekt. Videos zum Design von Komponenten sind derzeit nicht in Planung, wir werden aber eventuell später ein Video hochladen, das die Technik genauer zeigt. Wenn Sie spezifische Fragen haben, können Sie mich per PM auf der Tab "About" auf unserer Kanalseite kontaktieren, und kann ich einige Detailbilder senden.

Thanks! The spacer system is kind of a necessity. Slippage under the conveyors is very small, but even a fraction of a second adds up to misaligned cars, and eventually collisions in the terminals. This happens sooner than you might think, because as you may have noticed, the cabins are already packed very close together in the terminal. To answer your question: the conveyor motors (of which there are 3 in each terminal) are stepper motors of type NEMA 17 with 4 kg*cm torque, the main drive motor is a stepper of type NEMA 23 with 19 kg*cm torque. You can find these on ebay, or in stores that sell parts for 3D printers and CNC machines.

That's right, there's certainly a world of difference between the two in terms of sturdiness. However, structural rigidity is provided largely by aluminum T-slot extrusions and round bars, rather than 3d-printed components.

Thanks! Of course, nothing is ever 100% reliable. I'd say this system has a mean time between failures (MTBF) of 3 to 4 hours, by far the most common failure mode being haul rope derailment at the attach/detach bullwheels. If the operator notices this right away and hits the emergency stop, it is not a problem - if not, it usually results in a pile-up of cabins at the entry or exit of the terminal. This in turn causes other problems: very rapid conveyor tire wear (gone in a few minutes) as the tires' surface grinds on the carriages which are jammed, the rubber lining in the grip jaws wearing out equally quickly, and even haul rope slippage. You shouldn't walk away from the system and just expect it to keep running fine, but its failure modes are consistent and somewhat predictable.

@@TheTimmy376 thanks for your answer. 3-4 hours of running before failure is great ! Again, your work is amazing !

Who would've thought someone would one day find an actual purpose for such a system :) In terms of towers and terminal design: I'm convinced that if aluminum is used in the right places (or perhaps steel, but of course it'll be harder to work) to provide structural rigidity, then 3D-printed parts would certainly serve your purpose well. Keep in mind that as the specs of your system increase (length, tension, capacity, etc.), you must rely less and less on the 3d-printed parts as structural members. Using ~8mm dia 6082 aluminum (which we used to form the four legs of this lift's tower), you will be able to build a system of similar length which will be able to carry loads quite a bit higher than 0.5 lbs. Based on experience, I would advise strongly against PLA if you want your construction to last through a hot summer's day... Out of curiosity, are you designing a circulating or shuttling aerial tram? In any case, keep me updated, I'm very interested.

@@TheTimmy376 circulating v shuttling? Circulating being jig-back? That would be the ideal mechanism to use for balance. Also, small diameter metal aircraft wire would likely be used as the main cable material, anchored into the ground directly at the base of the mechanism, In order to keep tension. Also, I would like the cabins to be able to detach from the support cables, and eventually print a mod to make the high tension cables work with the gondola style station, and a nylon haul rope

@@charliesrandomthings5457 Right, so you are designing a detachable system?

@@TheTimmy376 No, a 2s 'Pulse' gondola.

@@charliesrandomthings5457 ah, now I understand. it makes sense!

Thanks! Unfortunately, we don't sell the CAD files.

Danke vielmals. Traditionelle baupläne haben wir eigentlich nicht, aber alle 3D-gedruckten Teile werden in CAD Assembly-dateien zusammengesetzt, die es sehr einfach machen, alle Maße und Toleranzen zu überprüfen, und als Referenz beim Bauen dienen.

Impressive attentiveness! To answer your question... well... It's complicated. This whole system is designed as a hobby project. There's just this one, and to be frank, it's not presently in a shape that we can stand behind selling it, in terms of confidence about its durability. To get the design in such shape and produce an additional copy would require quite a few more man-hours, which would have to be funded. If you want to follow through with your inquiry, please do feel free to send a private message (using the email address at the About page of our channel). In any case, thanks for taking interest!

We're on it ;)

Hahaha, make an offer ;)

Leitner, Poma....

@@GianniBarberi They're all going to be nuked before TheTimmy376 ever gets hired to work for any of those shitty companies... (that includes Doppelfucker)

The grip is what I call a "pincer grip". In the center of the carriage (Laufwerk) is a haul rope grip (Klemme), consisting of three longitudinally arranged hinged jaws (Klemmbacken), of which the middle one is opposed. All three are loaded by rubber bands to keep them closed, pressing against each other, and pinching the haul rope between them. For attaching and detaching, these jaws are opened by integrated levers (Kuppelhebel) visibly protruding from the bottom of the carriage, which are actuated by pressing inward. This is in turn accomplished by dedicated detachment rails (Kuppelstellen) mounted far forward in the terminals, shaped to gently but completely force open the jaws and release them as the carriage moves through. Once the carriage reaches the halfway point of such detachment rail, the jaws are fully open, at which point the large vertical attach/detach bullwheels (Kuppelscheiben) deflect the haul rope right into the jaws, or out of the way respectively. This process is perhaps most clearly seen at 00:43.

@@TheTimmy376 We have a topic on our forum, you are welcome!

Sorry, I don't think such a manufacturer exists. Presumably, the volumes are too low. However, if demand for this system grows, I may choose to further develop this design to bring it to a "sellable" condition. Or, of course, if a bidder is willing to cover the costs :)

@@TheTimmy376 This would be great! I would instantly buy one!

Yes it can carry some weight, as a matter of fact. Tension on the track ropes is provided by two 7-kg (15-lb) counterweights at the top terminal, which is enough to allow a few cabins to be loaded to roughly 500 grams (18 oz). Any more, and the cable sag would cause a deflection of more than a few degrees at the support tower, which would be unsafe as the cabins would have to negotiate a "bump". The cabins themselves weigh 92 grams each.

@@TheTimmy376 that is awesome. Definitely like hearing that model ropeways can carry weight. I build model Von Roll Skyway system here in the USA. Each cabin of mine can carry 1/2 lbs of weight . Been building them since 1992. Built 4 others with 2 more in the future. All CNC machined..

I've seen your build, it is very impressive. My compliments on the excellent workmanship, it clearly shows.

@@TheTimmy376 All of his ropeways are solid, solidly cast from actual steel. Not really much if any plastic machinery in his ropeways. Perhaps Robbie(Vonrollskyway1) makes THE MOST SOLID model ropeways of all time, with Claude Gentil's model VR101!

Stimmt. Deshalb sind Seilbahnen bei uns immer nur Sommerbetrieb :) Diese Bahn war August-September 2021.

Very well spotted. You are right, but some compromise had to be made, otherwise the terminals would've had to be impractically large. Including the depression tower in front both terminals, they are already 76 cm (30 in) long as it is.

@@TheTimmy376 ah oke i get it! It needs to be nice fot he eye but also a bit convenient in space. But to be honest it isnt that bad. The reason why i noticed is the part out of the station the gondels kind of gets an extra push to get to the corresponding rope speed. I also want to say geep up the good filming work! It is so nicely done. And may i ask where you live? I kind of get the feeling you are dutch (ben ik zelf)

What you're seeing there is the fact that the Lego gears we use have a ratio of 1.667:1. That means that the final speed increment is from 15 cm/s to 25 cm/s in a single tire transition, which is the cause of that last jerk you notice. And yes, in the east of the Netherlands. Thanks for your kind words!

Thanks! Unfortunately, this project is not for sale. If you're building your own and would like some help, we're happy to answer any questions.

Mi piacerebbe costruirne una mia si, però vedo la quantità dei pezzi usata, e mi piacerebbe avere una linea guida da seguire. Peccato che non possa vendermi il progetto :(

Danke vielmals!

No, the lift was taken down late 2021, then partially disassembled to allow some parts to be re-used in our 2022 detachable gondola. All parts remain intact though, and the gondolas are still assembled, some of which are serving as decorative pieces throughout the house. Reassembly could in principle be done in a few days with a bit of elbow grease.

@@TheTimmy376 it's a pity, you should think about selling it in a little series

@@Funivie_org We've considered it before, but decided it'd be too high-maintenance and would require too much support to keep running. Turning something this mechanically complex into a product I can stand behind is not trivial, and probably requires many hundreds of hours in additional investment, which we cannot justify currently. If a paying customer would be willing to cover such an investment, we would certainly consider it.

All in all, a little under half a year.

Ja sicher, die Laufwerkrollen sind die Nummer 42610. Sie dienen auch als Zugseilrollen an den Stützen und an verschiedenen anderen Stellen.

@@TheTimmy376 Danke! Bin grad dabei ein Funitel kuppalbar aus Lego umzusetzen und da fehlen mir eine Menge an solchen Rollen. Ein kuppelbares Funitel wäre doch auch ein tolles Projekt für dich!

Thanks! Unfortunately, we will not share any 3D files for this design. This has two reasons: the first is protection of intellectual property, the second is about protecting people from disappointment: having the drawings is one thing, but getting the system running and keeping it working requires constant attention and deep knowledge of the design and the engineering decisions underlying it. By simply sharing the STL files with a "good luck", we would be setting people up for disappointment. Sorry, I can imagine this isn't the answer you were hoping for. However, we encourage you to design and build your own system. Keep in mind that it doesn't need to be a complicated detachable. You will learn a great deal and experience much less frustration building something simpler :) . If you need help with any part of your own design, we will be happy to assist.

@@TheTimmy376 Ok thanks for the explanation. I can understand your concerns. However, if I need help i‘ll come back to you

No sorry, this model is unfortunately not for sale.

This is a hobby project designed from the ground up by yours truly. It also has gone obscenely over budget, so be warned before you make inquiries :)

Hi there. I would be really intersted in this project. do you have any documentation, STLS or plans? I'd be happy to purchase/donate for any guidance@@TheTimmy376
