2 AS Aufzüge Belt Cable Lifts in Basel, Switzerland

[@Biasca1]

Gute Aufnahmen! Die beiden Antriebe gefallen mir!

[@TheLiftDragon]

Dankesehr!

Interesting, unusual system with those flat belts. More maintenance and wear and tear but lighter than steel cables. Those rollers need some lubrication. The herring grate motor belt. I didn't know they existed.

[@TheLiftDragon]

Belt drives are the new way to go for low- to mid rise lifts and MRLs, at least that's what the manufacturers say. Installation is easier then with conventional ropes and it doesn't get your hands dirty as the belts must not be lubricated (else they slip). But in terms of longevity, conventional ropes are still superior and can last up to twice as long. The toothed belts on the motors are pretty clever. The angle makes engaging of the teeth more gradual, resulting in smoother operation. Thanks to the two symmetrical angled sections, the belt cannot slip out to the side.

Very interesting elevator drive system.

[@TheLiftDragon]

It indeed is. It's also something one might not expect at first but these belt drives are actually pretty common.

[@TheTheo58]

It's an interesting traction machine with flat belts. The belt drive does make the machine more compact not having the hoist motor protruding from the gear box. The elevator with the four belts 1:1 roping the hoist way looks more like a 2:1 with the location of the counterweight frame on the corner of the shaft, next to a guide rail. Thought the machine is 90 degrees to the two belt cut outs in the machine room.

[@TheLiftDragon]

The SGB142 belt traction machines are indeed very compact! They're also colloquially referred to as "the accordion" due to their appearance.

Nice cabling there, though there is a knock around floor 7 from something being out of tolerance, and the idlers in that motor room definitely need to either get the bearings lubricated or changed, as one of them is singing nicely. that size bearing normally does have a provision to lubricate it.

[@TheLiftDragon]

Being 15 years in service now, these are some of the older instances of SGB142 machines I know of and also that's about the time they seem to start developing such issues. Already encountered complete bearing damage at that age on another one and the unit had to be replaced. Though that was in a more frequented office building and at a speed of 1.6m/s compared to 1m/s here.

[@SeanBZA]

@@TheLiftDragon Here by me 60 year old lifts are still in use, on original gear. The new ones are the thing with a short life, not the units over 30 years old.

[@TheLiftDragon]

@@SeanBZA It's the same over here. There are still many original 60s and 70s Schindlers in operation but I bet we can't say the same thing about today's lifts in 50 years.

Sehr Interessante modernisierung 👍 vorallem 1:1 Aufgehängte Gurtaufzüge habe ich noch nie gesehen. Hatte letztens das bei einen Otis Gen2 Mod gesehen, der hatte den MR unsprünglich unten im Erdgeschoss und das Tragseil auch wie die Aufzüge ober der Kabine mittig besfestigt, vermutlich nahm man dadurch das ganze Otis Gen2 Mod Gestell (was ja eigendlich für die Insterlation im MR gedacht ist) und befeftigte es einfach oben an der Decke im Liftschacht.

[@TheLiftDragon]

Keine Modernisierung, sondern Ersatz. Das sind Ersatzanlagen, vom Original ist nichts mehr übrig (leider). Otis Gen2 Mod gibt es im Gegensatz zur SGB142 von Schindler nur in 2:1. Auch bei Schindler wird normalerweise die SGB zusammen mit bestehenden Kabinen und GGW eingesetzt, denn dafür wurde das System gemacht. Warum man aber hier alles ersetzt hat, weiss ich nicht. Auch die Möglichkeit, Bottom Drive Anlagen zu modden mit einer SGB im Schachtkopf gibt es bei Schindler. Habe schon mehrere solcher Anlagen gesehen, nur noch nie eine gefilmt.

[@Lifts_in_Austria]

@@TheLiftDragon Alles klar danke Für die Antwort 👍 ja mein Fehler natürlich wurde der Ersetzt 😅. Finde es etwas schade das es bei Schindler und Otis nicht möglich ist den Antrieb im Bottom Drive MR zu Installieren, da ist Kone find ich beim Minispace etwas flexibler.

[@TheLiftDragon]

@@Lifts_in_Austria Das ist so, da hat die EcoDisc mit konventionellen Seilen natürlich einen Vorteil. Aber ich sehe auch immer wieder Installationen, wo Schindler normale Maschinen für Antrieb unten verbaut. Beispielweise eine Ziehl-Abegg ZAtop oder eine Sassi Toro Winde.

[@LEVCKSHK]

Is the controller just the same as the Schindler 3300?

[@TheLiftDragon]

Almost. The Miconic BX is the motor room variant of the Bionic, which is the narrow one that fits into the door frame.

[@LEVCKSHK]

@@TheLiftDragon Thank you

[@ElevatorExploration]

You found two nice replacement facilities. I particularly like the lift on the left which has three leaves, it is the model of doors that I like, but today it has become a rarity, let's say I more often find lifts with 4 irregular doors leaves from the manufacturer Wittur and they are relatively very ugly and especially in a few years What will they become in therme of operation? Finally it is modernity and the choices of the customers who want that.

[@TheLiftDragon]

I'm glad you like it! 3 fold telescopic doors are very rare. Kone sometimes uses them on very small replacement lifts. The best modern day doors though are still manufactured by Meiller. Very solid construction and superior quality, much better than Wittur. But none of them beat the old original doors from 50 years ago - and that's what I'm working on for my next video. ^^

[@ElevatorExploration]

@@TheLiftDragon Ah great, I look forward to seeing your next video :D Yes, it's true that Meiller doors are of better quality than Wittur doors. Moreover, I prefer the Meiller doors, but today the vast majority of manufacturers, both large and small, buy their doors from Wittur because they are cheaper.

[@Migueljuegos]

Whenever I see one of these, I always wonder what advantage it has over a traditional steel cable system. i.e. I guess the belts have less durability and have to be changed more often, in this case even the motor has a drive belt. The maintenance of these elevators seems more expensive and I do not see any advantages at first sight, maybe a lower energy consumption?

[@TheLiftDragon]

Easier and faster to install because less belts are required than one would need conventional ropes, convenient for the technicians because no greasy fingers. Also the system is much more compact which makes it suitable for MRL. Energy wise I don't think they're more efficient than conventional cables because the rubber of the belts gets slightly deformed while travelling over the sheaves and that generates heat, though I think this effect is very minor. I personally prefer conventional ropes over belts but it's just the way the industry is going nowadays. The only belt system that sets itself apart from others is Kone UltraRope, but that is a special system with carbon fibre cores and is for ultra high-rise only.

[@Migueljuegos]

@@TheLiftDragon Oh, I see, I hadn't thought about the ease of installation.
