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.
...mrmattandmrchay is me (Matt) and my son Chay.

Note: Please do not contact the organisation here, this visit was pre-arranged as we're an internal contractor working on a different system.

Being an old building, the lifts are in great condition and very happily unmodernised. The buildings architecture is great. A really good, well detailed and documented video.
Modernised a bit, with the inductive sensors taking over from the shaft switches. The original Express used a big shaped guide on the side of the car, that was large enough to catch the switches, irrespective of position, and then, using a middle of chute channel, would set them into one of 2 states. Above car for those above it, and below car, for those below it. this set of switches drove the logic, and also drove the indicator panel, as the one set of contacts on the large cam on the switch would operate during the change over to open the short across the series connected floor lamps, and thus the corresponding floor lamp would light, till it went past the next, which would, as it changed state, flip to indicate the next, with a large power resistor there to limit current flow in the lamp circuit. 24VAC lamps, running off a 48VAC tapping on the power transformer, and the resistor was high enough power to withstand the lamps shorting to ground. Lamps only needed one wire per landing, plus one extra, to operate them, and typically you had a ground floor one, and one in the car.
The other function of the switch was to stop the car on the landing, using a second set of change over contacts that would cancel the floor call when at the floor, and also stop the lift, as it no longer had any call, till the door relay timed out, and allowed the logic to look at the floor status relays again. This was single speed, made in 1939, and was still running till around 2000, when the controller got modenised with a digital one, using still the same lamps, switches on landings, but with a new trailing cable (not enough non leaky cores in it, though the new cable got eaten twice by the car, blowing 2 controllers up properly, as they got 230VAC fed into the 24VDC power rail) and car call panel. The 2 speed one just had a second switch that would operate the half speed function, holding till the main switch operated and stop the car.
Was an art to get this to stop perfectly level both up and down, not helped by the shaft being slightly out of true, so you could have the car at some floors float out of the switch chute, but not out of the guides, and skip floors, till it would stop at the next floor. Only affected the middle, old shaft guide rails that had relaxed, and moved about 2cm from true, and if you adjusted the guide shoes (cut down Otis shoes) to not float, you would run at other spots.
The production value of these videos is incredibly polished. It’s like I’m watching a PBS show
Wow massive compliment. Thanks very much 😀
1958? Same age as me. They are in top shape... wonderful to see... very glad you were given access and guidance by the kind lift engineer.
Absolutely! Thanks for the comment. More parts coming soon on this.
I recently found a 1930s Express lift in a shop in Skegness, all original & still working!
The brickwork in the shafts is beautiful, a far cry from the ragged work seen in other buildings. Great video, rather sophisticated for a 1968 system. Now, onto Part 2!
minus the lamps that aren't working these lifts look like nearly mint condition - it's clear they're taking excellent care of them and hopefully that continues to be the case for a long time yet. Very strange external indicator behaviour only lighting up when there's a destination pressed inside, kinda defeats the purpose of the indicator's existence...indicating the lift's arrival! Looking forward to the next part :D
I wonder if the are struggling to get the bulbs now because the rest seems in superb condition and no corners cut, incandescent lamp production has been winding down for the last 20 years.
The coolest lift system I’ve ever seen was an original mid 50’s 14 floor Otis Autotronic. They still ran like brand new.
This is by far the most uplifting video that I've seen all day.
What beautifully maintained old lifts. Found this really interesting. As always, another excellent quality video from MrMatt And Mr Chay. Thank you!
It's amazing how a series of contactors can control an elevator. With solid state computers, you can probably duplicate that function with a $20 raspberry pi. Great content!
You could probably duplicate it with a $1 microcontroller and some sturdy IO chips.
@@user2C47 LOL, so true ... still you need to put up a decent board that can stand the time, discharges, EMC events (so much wiring exposed) and keep working unatended for years. But yes, any PIC18F would be enough for the logic and even handling a 4G modem for alarms. Well, they need to comunicate with the numerical displays that can also put (scroll) messages (probably a 485 arrangement).
@@38911bytefree Floor displays are an array of relays, powering lightbulbs, no RS485 here.
Dude, you seriously deserve so many more subscribers then you have, the amount of effort you put into your videos is outstanding
Thanks for the massive compliment Lachie :)
@@mrmattandmrchayyeah you deserve like 10M subs best effort quality details and graphics
Hey. I've used these lifts before. I recognise the call buttons. I never knew they were from the 60's. Now I feel like I was privileged.
Yess more vids. Keep it up.
Hi Matt how are you doing mate? Great to see another rare lift video these Express Lifts are awesome they certainly have lots of character crazy that they was manufactured in 1968 but has added bits years after it was installed e.g. the alarm with the backup power supply, how's Chay doing is he all good? and hope your having a good evening so far Matt and keep up the great content on the channel as its so interesting and entertaining to watch 👍
Exciting stuff, amazing you are getting this level of access for filming. Can't wait for the next parts.
Great job. Express DMR is fascinating. Looking forward to part 2.
What an awesome episode, can't wait to see part two! And a snippet of the video that started my fascination with your channel many years ago :D
thats amazing I think the management wanted to keep the old elevators working as far as they could without mod
Your videos are always superb and top quality. excellent video.
Thank you very much!
Sadly since Express were taken over by Otis for their service contracts and shut down you can see the level of maintenance has gone down. Usually during the monthly maintenance visit the Express engineer would have a bag full of bulbs and replace all that were dud. Still lovely lifts that most modern manufactures can't get close to for quality.
In our four story office building we have two lifts one for passengers the other for goods. Both have been working trouble free since 1929
That building and its lifts are in amazing condition. Love those bricks! Awesome architecture👍
Express were a big fan of Bottom Drive machines. The only issue with them is the amount of barings that will end up requiring replacement and the struggle to replace them and even re-rope them. Other than that they are a delight to work on.
Amazing Lifts, never seen them arrow lanterns before.
Me neither, that was the first time I’d seen them!
I would love to have a look at those really old fashioned ones with the long flattened arrows.
Very interesting arrows - they almost remind me of Fujitec ones! Shame none of the bulbs in the car indicators work - at least the bulbs in the buttons work!
very nice and amazing content and graphics keep it up mrmattandmrchay great work
Thanks for the nice comment :)
Pure excellence once again. Thank you
i watched you since 2014
nice one! Thanks
Interesting how the engineer’s safety stop roller switch looks like a retrospective addition.
Another amazing video! I have always enjoyed your productions.
Great explanations. Looking forward to the next episode. Thanks.
I find elevator logic systems somewhat akin to automatic telephone exchanges of the same era and their use of seemingly exact same logical relays
I hope you bring me Hilton park part 5 because I'm really interested to see Hilton Park part 5 it's about a direction switch
when the doors stay open on a elevator with no calls in place is called peek up in US not sure what they call it in UK
That’s amazing…how rare! Kinda crazy how there’s no computers involved!
The quality of your channel is very very high! I’ve subscribed :D
Btw I can’t find answers on the internet so can someone pls tell me how to tell the difference between hydraulic elevators and the regular ones? Thanks!
I am having one in maintenance... But in poor mechanical condition (about 1-3 years left)
2nd one is dead because of gearbox failure (previous maintenance company just dropped counterweight and disassembled whole lift
Very nice classic quality shame they not to this quality today
Wow look at those relays 🥰
The relay controls look a lot like a mechanical telephone switch of the same era; likely no coincidence.
Great video as always great work sir
I film lifts for instagram. Your content is amazing
Thank you very much :)
Question. Can you tell me please what type of lamps are used in Car Position indicators, and what voltage they run on ?
You can see them much clearer here: th-cam.com/video/C3QFo7wyPKc/w-d-xo.html The lamps are between 100-110volts and have a bayonet fitting (push and turn).
Build to last👍
Where is it?
I love these videos, despite having a irrational phobia of all things lift shafty and plant roomy. I have to look away sometimes when you tip the camera down the shaft. It's bloody stupid I know but I can't explain it.
Were there ever duplex lifts where one lift is the "counterweight" of the other, having only one motor?
th-cam.com/video/wDvtrWtP-1c/w-d-xo.html see 6:30 onwards. Can't think of any other lift for these reasons... car 1 can't move because car 2 not ready. Weight differences between car1 and car2 will vary and not efficient. If car2 empty and car1 full, not efficient and motor would struggle. Having a counterweight is probably easier to install then having car 1 linked with car 2. With 2 lifts linked, need a bigger motor and if only one car has passengers then a waste.
They are in really good shape, made TO LAST.
These are mint for being more than 50 years old.
Call that old should have seen some of the stuff I worked on on Otis it was called a vip 260 high-rise group lifts now that what you call a Elevator
Wow belt drive.
never understood that style brick on interior spaces, my school had them and so do many other public buildings around me, used to straight up destroy jackets and schoolbags as you hustled along the narrow corridors.
It’s extremely hard-wearing, virtually maintenance-free, cheaper to construct and often has an attractive, uniform appearance.
I have an irrational fear of scissor doors.
Nice video, keep it up
Thanks
Cool
Awesome
Why is the shaft lit up? It's not usually like that.
Pretty much all lift shafts will have lights in them to help with maintenance. The engineer switched them on so we could get a better view :-)
I want to buy these
The first real, working elevator was installed in 1857, how do you think elevators from 1960s "early" elevators?
What is meant is that it’s the first technology which allowed multiple lifts to run automatically in an advanced fashion rather than a single lift with a manual operator.
:-)
U.O.B. - Universty of Bradford?
Those look like the ones u guys got stuck in
what does the word duplex describe there?
It describes the fact that there are two elevators which work together.

Down-voted for offences to English grammar.
More like spelling issues to me, but that's ok because English has a vrey borken spellig sysem.
Video would be better if you spent less time telling us over and over, what is either coming up next, or what is in part 2. Also, it's all over the place. No logical flow of what you're trying to tell or show us.
Well, there’s a lot more to learn and know than can be put into a 14, or even 30 minute video.
If you’re actually interested, the whole channel is full of this content, with videos dedicated to specific parts.
This video is more of a general overview.
@@Lift.Tracker Being able to compress a video into 14 minutes and being able to structure a video are two very seperate skills.
Actually, the bad and confusing quality of this video made me stop watching it.
This wasn't a time to say to the other guys, "hang on a minute, can I retake this footage?". I'm not making a blockbuster film here, I'm following a lift engineer, then spending a lot of time editing it to make it as informative as possible. If you don't like the "bad and confusing quality" (??) of this video, then you're in the minority.
