IMPORTANT NOTICE ABOUT SAFETY AND TH-cam:
My channel does not promote or glamourise dangerous activities like lift surfing.
Featured in THE SUN and THE MIRROR newspapers:
• Teaching KIDS TO SURF ... (see this KID trying to surf a lift)
VERY WORRYING...
• Random lift adventure 13 (12 year old kids surfing lifts)
mrmattandmrchay is a RESPONSIBLE and RESPECTABLE channel.
It goes without saying that TH-cam is a public platform and our channels are popular with kids, and kids are influenced by what they watch. I'd like to think these kids didn't get the idea of surfing lifts from 'my' channel.
A warning in a video DOES NOT exonerate you if harm should come to a kid that was copying something that YOU have portrayed as a fun activity.

THE MRMATTANDMRCHAY CHANNEL, established 2008:
I'm passionate about uploading quality and interesting videos for YOU, my audience.
What is my channel about? "Old lift machinery made interesting", old air-raid sirens, prehistoric alarm equipment. If "I" don't find it interesting ...then IT DOESN'T GET UPLOADED!
I always spend a lot of time editing my videos with animations, video in-sync with music and voice overs to bring you QUALITY videos to watch.
My moto - "Quality NOT Quantity" - spending a month editing a video is not a rarity!
But without you, I'm nothing here. Thank you so much for watching.

As i supposed the motor brake is very similar to the demag brake motors with conical rotor.
If there is no additional winding for the brake it basically has to be a conical rotor since otherwise the pull force won't be very strong.
Of course the design is a bit different but the fundamental principle is the same.
Very interesting comment! Every day is a school day! :)
I know there are some motors that use a spring loaded disc brake arrangement, small enough to fit under the fan end bell. They have a separate coil that is ~2" thick and the wires are routed through the motor housing to the motor junction box.
That Otis passenger lift had the most character of any lift on your channel.
came to youtube after 4 days and saw this video first!😀
Matt, thank you for the quality channel! You take us to interesting places and very well explained!
Somewhat disappointed that these air traffic control shape structures with no public access (Lancaster too) turn out to be abandoned restaurants. Always thought they were the control centres for the UK motorway signage etc. Fascinating how the electronics/mechanisms for the lifts work though.
Matt you make some of the greatest most in depth videos of this, keep going
I work in a 1950’s “new town” chemical plant. The warehouse has its original Otis goods lift and there is tons of old stuff still around the place.
It’s best described as looking like that chemical plant on Batman (minus Mr Keaton and the gunfire….).
The brake mechanism reminds me of a clutch disc in a manual transmission car.
I love this old Otis gear, spent many years looking after UMV's with complete floor setters and selectors.
I'm watching these videos with some trepidation as like you I have terrible phobias for both water tanks, lift shafts and equipment. I have to make a great effort to look when you tip the camera to look down a shaft. It's a totally irrational phobia but debilitating nevertheless. I went to photograph a gas holder that is being demolished in my local park, it has a great gaping hole cut in the side of it exposing the internal structure and it nearly drove me crazy with fear until someone else came walking by with the same curiosity and I was fine as we discussed the task in hand for the demolition company.
This would be very different if it was serving more floors
Now I've learned something new. Excellent video as always! Weird how the stockroom and tower landing doors aren't level with each other. They could've made the landing door on the stockroom level slightly higher.
Awesome explanation! Thank Matt!
Glad you enjoyed it!
@@mrmattandmrchay They are always great! I patiently waiting for the next video is always well worth it!
Thank you very much for doing these videos for us!
Hi Matt,
Again, a very good and detailled video! This type of machines is fornas far as I know only used by dumbwaiters and not for passengerlifts. So that is very surprising to me. As written in an other comment the brake is similar to a hoistbrake. In have a picture somewhere on my laptop were that part has been opened. It works with a magnet inside.
Hi Joris. Ive sent you an email, asking for a bit of help with something. Pls take a look if you have time. Many thanks. Matt
50cm is probably a good world record contender for the smallest distance traveled by a lift.
Nice building, they could just refresh it a little by painting it and putting chairs and tables and turn it into a kind of lounge. For those traveling to relax a little.
I love learning about stuff like this
A lot of worm drives cannot be driven 'backwards' through the drive, depending on the angle the worm is cut and the teeth on the crown gear wheel. A lesser angle (or finer 'thread' on the worm gear) gives a greater reduction in speed and increase in torque and is also much more difficult, if indeed at all possible, for the crown gear wheel to drive the worm gear. In such a scenario, any brake would be a 'belt and braces' approach just to be sure nothing could move.
somehow i never caught on that there was a slight split level setup going on there between tower and stockrooms. Definitely less relays than most other old otis lifts by the looks of it, although with the simplistic nature of it that's all it needs really. excellent video
very good
THAT IS DANGEROUS
Come over to Leamington Spa, Warwickshire and into our town hall. Try to get special access or go on a tour.. we’ve got an old 1920s lift which shakes when you jump inside it
The video is so soothing
This is definitely a minimalist basic lift but, for a simple little goods lift, why have more expensive complications?
The “Shaft Switches” were just one of the many variations of the 6098 switch and did away with the need for a selector.
Floor relays were always designated from 1F, the lowest floor, up to TF, the top floor. This was just standard practice on Otis however basic or complex the system.
No wonder the crown wheel on your demonstration lift is missing. They're made of reeeally nice big heavy hunk of juicy bronze. Learned that while dismantling an old lift. Been questioned then on where it went. The wheel that is. But it was easy to get my teams hands clean since we had someone else deal with the scrap. And brainwise those workers were just one chromosome away from chimps. We just went "Well I'dunnoh. Wasn't moine job to deal with scrap." :D That thing bought us quite a few beers and a pack of cigs for each one of us that night. Had to cut it in half to get it outta there. Almost tore my arm in half. :D
Excellent!
Looks like the lift shaft goes down to the loading dock, just not the lifts guide rails. I think the stopped using it because it was virtually useless for the day to day operations of the building.
hello again Nice Video keep the work up!
Do Lancaster Forton exploration too
That was interesting
Elevator on floor switches, something in the Soviet)
Superb video! I've never seen this arrangement before - where the metal dome at the end of the motor is forced away from the main motor housing, to move the lift.
When the brake is on, does the system rely purely on friction to hold the lift still, or are there other components?
With a normal contactor - the electromagnet, when energised, causes the metal contacts to experience a force, pulling the metal contacts towards the electromagnet. Here, it's the other way round - the electromagnet pushes the metal dome away from the main motor housing.
How has the electromagnet in this motor been designed so that it repels instead of attracts?
Sorry for bombarding you with questions!
It's a worm gear so very little force on the input shaft is needed to keep it from rotating. The rotor of the motor is probably slightly offset from the stator towards the output side by a spring so when the field windings are energized they pull the rotor into the stator which moves the metal dome away from the housing disengaging the brake so no separate electromagnet is needed.
thank you
Why didn’t you call goods lift c when you were in the tower?
awesome
Part 5? Yes or no 🎉
Interesting films indeed. Does anyone know what make the lift was in the sound effect that all the old James Bond movies use? You know the sound, the one with the loud brake slow down noise. Holby City and Thunderbirds used the same sound too. It’s something I’ve been trying to get to the bottom of for years. Thanks.
I know exactly the noise you mean. It was thought of as a "normal sound that a lift makes", but probably from the 1920s!! I don't have it though unfortunately.
@@mrmattandmrchay I couldn’t believe it when Holly City started using that sound before the series ended production. The original 1950s passenger lift at the Tyne Pedestrian Tunnel made this exact noise before it was modernised.
@@scammell23I have never watched Thunderbirds or Holby City and the last Bond movie I've seen is from the 90's. But I instantly remembered that specific "elevator sound" when you mentioned it. Thanks for bringing this up, it would be really interesting to know where the original sample was recorded 😄
I've also sometimes noticed the same "thunder" prop noise being used. Many of these samples propably date back to the reel-to-reel days 😄 (now obviously digitized)
hey matt
the brake is on the backend of the motor.
its the safety gear on the car not a brake, the gear has eccentric dogs egg shaped that bite into the guides, only when the ropes fail.
stannhah are notorious for using brake motors, there a pain in the arse.
in the its called a delay off timer thars 2 to 5 seconds from the car to the landings they also have an AQR timer anti quick reversal timer that stops the motor from reversing quick.
Just curious, are you a lift engineer or are you just really interested in Lifts?
He's both
@@brunoais Trust me if you're a lift engineer the last thing you wanna do in your free time is go look at lifts lmao.
@@DEN8Y On the opposite.
He's an lift engineer and his passion is old lifts. He's completely starved for old lifts. What's boring for him are the modern lifts. He mentions how the lift he used to go down is boring (see part 3).
(I wish I could show him 2 old lifts I know but it's in a completely different country than he lives in and has a floor selector he hasn't shown on his channel yet)
Hey Matt I Got Stuck In A Lift
There's an interesting video by 12voltvids, with him stuck in a lift for three hours. And the absolutely useless OTIS emergency phone.
So the motor on this lift is a single phase 240VAC?
3 phase
@@leewilliams6070 Can't be, the main contactors for up and down are only 2-pole rather than 3-pole! Quite unusual!
you're in backrooms
First
the lift company who's motto is "We hate to Brake it to you"
Stopid elevator
Superb! I think the record for a short travel lift must be at a care home I've visited where the lift has doors on two adjacent corners to facilitate a 2 step (1 actual stairnose) floor level difference between the main building and a newer extension.
Rex’s name and date on the safety rope support girder is two days after I was born.
2:51 I noticed a few segments on the counterweight are missing thats odd
I imagine elevator maintenance has its ups and downs.
