My pleasure. When I upload something, if "I" know what something does, I love explaining it simply so that my audience also learns something interesting and new!
A great find and a fascinating video. There’s lots of interesting parts in there that I’d love to have a more in depth study of. I find it surprising that chain drive isn’t used more. I have installed and maintained chain drive in London but they are certainly rare. An old goods/passenger lift had a car that was carried on a chain at each corner. The machinery occupied three sides of the motor room with bevel gearboxes in the corners and driving/carrying sprockets in all four corners. A small dumb waiter that I installed was pretty much standard except for a pair of chains instead of ropes. Ropes are just considered standard these days and are probably cheapest and easiest for the higher rises.
I've come across a more recent chain driven elevator, installed relatively recently, which is actually used to lift the carriages for an amusement ride. I found that quite interesting by itself, so this is really good.
Im so glad that some of them still work. Its a shame some are derilict. Im kind of sad they modded the controller. Hopefully they dont mod the motor. :(. Thse are very unique lifts. Keep up the "Quality not Quantity" slogan! This is my go-to channel when im in an elevafor mood, lol. Old lifts tend to work better than modded ones. If they mod these, they just made a 9999 billion mistake. The ones that work run perfectly fine.
Looks like that building originally had a good number of incinerators in the basement area, at least 20 of them, and with those doors looks like it was at one point a crematorium, using town gas, and later on natural gas, to cremate things. With the age of the building, those ceramic tiles will not come off the walls, they were most likely placed there direct onto wet plaster, after getting a bagwash of cement powder on them, so they are essentially one with the wall.
After all, for such a relict mechanism I'm kinda happy that they modernized the control board. Not only currents are reduced (any spike of current causes rubbing of wires in the coil, so smaller spike - longer insulation life) and also mechanical stress is reduced. I don't see the value of having old relay-based controller on 80yo working(!) lift. The main value is the drivetrain, how it's connected to each other. And they did preserve it with a great care. And yep, I love to see old DC lifts with the original control hardware... but they're passenger lifts, with a low throughput. Such an amazing experience of being able to see them in work. For freight lift I personally would also change the old control board to VFD, but probably leave old board just sitting next to it, as a piece of memory
As an ex lift engineer for both A MARSHAL HUNT now no more and OTIS I have never seen such a lift a great find and very interesting to me thanks alot .
Well what do you know, I never knew they ever build them like that, simple yet very sturdy and basicly nothing that really wears out if you keep it all lubricated.
Interesting. The only elevator I've ever seen like this in the U.S. was a large dumbwaiter in a Chinese restaurant in San Luis Obispo, CA. I remember it was really noisy when it operated. Also, the Tower Bridge in Sacramento has a giant-sized version of this to lift its center span.
excellent video covering some very unusual lifts (Elevators) as we call them. I wonder if parts were taken from the one lift to keep the other one going due to parts no longer available?
From looks of this lift, chain had some advantage over steel cable: its drive cog may be much smaller diameter than sheave, so it may have higher rpm for the same speed and that means simpler drivetrain. Though here it is still 2-stage: first worm gear then good ol straight gears. But with cables i presume it would be even bigger. In passenger lift (low weight, high speed) it could be even direct drive! In some sense, it is modern belt lifts' grandad. They are pretty popular today as belt sheave also may be very small diameter, hence direct drive and no motor room whatsoever. About working lift in this video: I'm afraid not only control was retrofitted with VFD but motor as well. Old motors were cylindrical in shape while rectangular ones are usually much newer, like 1980s. At least that's when standart industrial series of rectangular motors came around.
Just as i thought the Day coudnt get any better, you uploaded a new Video. Anyways great Video but why do these Lifts use Chains instead of Ropes ? Is there any particular reason why ?
I am not an elevator mechanic, however, I would think that a contributing factor is that chains are generally considered immune to slippage which gives them a considerable advantage when you need to repeatedly place something precisely in the right spot. Over time, and with large enough loads, ropes and belts can slip, which might throw off the position sensors, leading to doors opening at incorrect levels.
The surroundings felt familiar. You can't hide the large blue furniture store! The airport, the French language, the Swiss sockets. This can only be.... Actually... I have passed that Ikea store multiple times.
Im very sorry but im going to have to remove your comment. I tried hard to hide the location to protect the maintenance guy who allowed us to film. If you would like to repost but pls dont mention the location. Thanks
Some ,hopefully constructive, criticism: When trying to keep locations a secret. Try to keep anything unique, and especially very recognizable, out of the picture. Or don't show any surroundings at all if that is not possible. Very tiny clue's not blacked out can give a huge amount of information. Thing also with blurring is that can be reversed when knowing the exact algorithm used to blur things out. Sometimes pixelating or even blacking out is required such as when typing in a code on a keypad. Second maybe put a (pinned) comment notifying that you want to keep a location a secret and that any moron, like me, who does spoil it gets instantly deleted. Saying it in the video itself means it can be skipped over. Want to let something be known broadly? Advertise it over and over.
Genuine question, was there any sign of a manufacturer name? Don't think one was mentioned in the video, and it's such a unique mechanism I'm assuming it's not a major manufacturer 😅 (Edit - Never mind, Schlieren brakes, so Schlieren)
Continuously publishing some of the best elevator content in the world.
MrMattandMrChay do a totally excellent job with their elevator videos.
Thanks so much for the explanation of the floor selector at 11:00!
My pleasure. When I upload something, if "I" know what something does, I love explaining it simply so that my audience also learns something interesting and new!
Thanks for another brilliant video. Never seen chain driven lifts before. (That pit has to be what nightmares are made of)
Wow! Awesome of them to let you film that antique equipment!
Thanks so much for this video!

NICE TO SEE OLD LIFTS THAT DO WORK BUT WITH NEWER DRIVES

I don't agree. What interests me is the relay logic.
This was really something new. Never seen those chains before! Thank you for finding all these old lifts.
Love these! Anything scary and mechanical, I'm in, Thanks!
As an ex lift engineer for both A MARSHAL HUNT now no more and OTIS I have never seen such a lift a great find and very interesting to me thanks alot .
Cool, glad you liked it and thanks for the comment. BTW, what's a marshal hunt?
Lovely lifts , thank you for bringing them to us to enjoy.
transition from a part of something to a intro is perfet
These lifts are somewhere in France as Passage interdit and march, arrêt are French words. Awesome machines.
Great video and intro is best
Well what do you know, I never knew they ever build them like that, simple yet very sturdy and basicly nothing that really wears out if you keep it all lubricated.
Awesome videos as always. Thank you !
Another fascinating and educational video, thank you!

12:41 that would be called a dashpot and normally there filled with oil, they work a little like a shock absorber.
Yoooo that so cool

awesome video
Lift pit with groundwater - standard for any pits. All is OK. 😊
That lift pit…. Imagine having to clean that up, I’d be a nightmare! The mechanisms look like bicycle chains on steroids.
Those hoisting chains were hand made, from the hammer blows used to fix the links together.
A Marshal Hunt was a lift company in Bristol installing lifts into mental hospitals and the like.
How are those chains lubricated? I saw no oilbath or something.😮
🖤🖤🖤🖤🖤🖤🖤
what were the numbered rooms with the arched openings?
I have never seen a chain one. Like a big bicycle chain. Wonder if it's ever come off...
The chain the size of your hand - it's massive :)

@@mrmattandmrchay I Have edited the location out of my comment.

Very very cool, albeit very slow! I'm not sure I'd trust chains, even though those ones are massive and heavy duty haha
that good lift looks like it should have another floor above.
It’s quite interesting to see how these work.
Suggestion: avoid red text on screen due to many people having red/green colorblindness.
Thanks for your comment and suggestion. Ive changed the text in my next video to light blue and will remember this going forwards.
Looks like the sprockets are worn, don't think the chain suppose to ride on the outside edge of the sproket.
Shouldn't the derelict motor rooms have a lock out tag out?
Even if the rooms are unpowered, you never know what could happen.
The guy talking about the resistors sounds very Dutch 😂
Yep, he's dutch! :)
i saw a lot of french stuff, is this in france ?
May be Switzerland, because also a lot of German
At 7:02 he asked what „Baujahr“ the building is that is German for year of construction so pretty sure Switzerland
Also at 12:09 it say Geneva on the sign
Is in vernier
Genuine question, was there any sign of a manufacturer name? Don't think one was mentioned in the video, and it's such a unique mechanism I'm assuming it's not a major manufacturer 😅
(Edit - Never mind, Schlieren brakes, so Schlieren)
Hi mate
ｕｈｍｍ， ｔｈｅｒｅ＇ｓ ａ ｂｉｔ ｏｆ ａｎ ｅｃｈｏ！
you could say that :-)
Brunner, Schlierer
Hahahaha that lift pit was disgusting
It's chains all the way down.
Nothing new with that pit.I have one Kleemann (14 years old building) with same pit,oil and underground water.
Mais c'est interdit, ça.
