Tip for the mechanical code locks. The order that you enter the correct numbers / letters does not matter, so long as the correct ones are depressed. The "C" button clears any previously depressed buttons. Look for fingerprints on the buttons. Press "C" followed by all those with prints or worn surfaces. That's it, lock open. If prints are not obvious, polish the buttons up with cloth, sleeve etc and return after a few people have unlocked it. Prints can now be seen.
I share your phobia. Without someone else holding my hand I couldn't have gotten past those tanks and pipes, although I knew full well that they couldn't hurt me!
+N.E.A. Elevators It was originally one video, but when it went into 20 minutes I decided to split it, get the first part uploaded asap and complete part 2 for next time :)
I would have thought that you would encounter water tanks quite often in that kind of work with Tanks often being situated on roofs. The college I was at in the early 90s had a couple of Otis lifts from the late 60s on two sides of the building. The roof on one side was visibly strengthened and you knew there would be a large tank above!
Ah you mean the music in the back ground when the warning appears? Yeah, it's quite cool - actually I forgot about this music and might replace my music on my latest videos which are coming up very soon!
aha! I am very excited for these new videos you speak of, i can't help but watch the DMR lift, this lift, the massively informative lift and the express lift videos over and over! I think I've found a channel that makes me feel welcome and also makes it hard for me to resist watching everything over and over!
Cool! I'm generally really glad that you like the videos. As you'll see at the end of my next video, I've added "MR PERFECTIONIST" to my video filming criteria!! I spend a lot of time perfecting videos. Sometimes when one of my videos takes months to edit and it's not very popular, I think "why did I spend so much time on it". The reason I do it is this is "me" - I love going into detail about how things work and what I've found. "QUALITY NOT QUANTITY" is what the mrmattandmrchay channel is all about. And it makes me really happy when I get good feedback from people, which I have to say is 95% of the time. :) Also, I like engaging with my viewers. I'm always listening and I try to respond to most people, but sometimes the sheer volume of comments and messages is difficult to manage!
The community here is few and far between, no other RUclipsr has communicated directly to me as often or as thorough as you do, and it does really make me feel happy to know that watching a video on what I love, leaving feedback and getting a reply from the man behind it all really makes my day :)
I don't know what that big wheel is called (the one being peered into at the 10:00 mark), but I absolutely LOVE the "power down/power off" noise that it makes (if that IS the source). :D I have a deep-seated love of mechanical-electric sounds, and something about that one is downright satisfying. :)) I can't explain why; it is what it is.
i am 11 years old and i like to play with relays and electrical stuff too. i wired up a relay to a fan and a thermostat when the thermostat clicked on the rely would contact and fan would turn on but lots of wires exposed but only 120 volt not 415. whats the worse elevator /lift you have worked on?
I think Schindler is my favourite as well, but followed very closely by Otis and Express. Bennie is the least interesting to watch as all the relays are encapsulate so you can't see anything moving unless you look closely. Even their floor selector system is relays, which I'm covering in a video coming soon.
+Michael “Mike i386” Roll It's like they are in no rush to modernise it. Might be there for next time, as I want to examine that selector in more detail.
I would definitely be wearing insulated gloves and using an insulated screwdriver to be pushing in relays. 24 volt relays or 24 volt coils did not go into effect across the industrial field till about the late 90s. Majority of time going back to relay logic systems like this the coils would be 110. Which definitely I have to say is a little sketchy watching you push it with a little precision screwdriver. Anyhow pretty cool video by the way
Hi I find the concrete platforms where the lifts motor+gear assembly sits on (with the holes for the cables) often look as if they could crumble/break. Could that happen and wouldn't the lift fall down ?
Pressing the button places voltage to make the relay switch on. When the relay is on, this places a by-pass across the button, so effectively the button can be released whilst the relay puts a short circuit across it - this is a what a latching relay does. So whether the button is pushed in the lift car, or I press the relay in manually, same effect. The call button will illuminate when-ever the relay is latched. The buttons inside the lift would also light up.
Also see this - ruclips.net/video/USmuJCOXbgk/видео.html This is me in the motor room pushing in the relays, then pulling them back out again to unlatch them. As you can see, the floor indicators light up and go out.
+mrmattandmrchay Our switches have three positions. When the cab is below, the switch is latched right (and vice-versa), when the cab is at the floor, the switch is held in the neutral position. This system is used only on relay controllers without memory.
When the lift is approaching a floor, how does the motor speed control work on a lift that is all relay logic. I didn't see any variable frequency drive (VFD) controller. Does a relay switch in a big power resistor to slow down the motor just before a floor?
The motor has two windings, so the motor has two built in speeds. With a VFD you can generate any speed, but before the invention of VFD drives the only way to do it was with a DC motor and an AC to DC generator to run the motor. The resistors prevent full current getting to things like motors so that if the motor was jammed then the resistor would heat up rather than the motor. It also has something to do with residual current from the motor being arrested by the resistor if I remember correctly!
Yes, glad you mentioned that. Recently I've looked at this video featuring a mine shaft elevator... Also interesting! ruclips.net/video/9eadj3kL_fM/видео.html
I think you would like the water incline lift at the centre for alternative technology near machynleth in Wales. It has a huge drum that the cable winds on to.
+MiLAN Certainly is, as far as I know two relays should do it - the Main Contactor relay delivers power to the direction relays and should only switch on when the lift is ready to move and the safety circuit is made (i.e. all the doors are shut/locked). This must be on and then the direction of travel relay (up or down). Press both relays in by hand and it should take off, until you let go. I'm not going to try it though! I the controller WERE to request movement (up/down relay) then unless the main contactor relay is on, lift won't move.
you can press them with your finger if you know what ya doin or use a short from pf to ca1 ca2 etc the car top control is an upgrade scindlers didn't meet uk standerds the big grey wheel is the floor selector ther a nightmare i am a lift engineer ask me a question
Yes, it's the thing in the middle. Take a look at this video and I tell you in detail how it works - ruclips.net/video/YX7lqT3oNl0/видео.html Very interesting stuff. This is the thing with old technology - you can study it and work out how it works. New lifts - a circuit board. Not anywhere near as interesting!
+David Irwin (passacaglia28) I'm going to have to point you towards my Q&A, see 3:17 as I answer this in perfect detail, but in summary, yes, it was when I was about 6 years old I removed the lid from my Nan's toilet cistern and didn't expect to see a large green limescaley hissing ballcock!!! .. ruclips.net/video/LBzik-XthE4/видео.html
6:36 I was wondering how many cables this lift has, 3? 4? 6? 8? [Motor stops] Motor or flywheel: TWOHHHH Okay the flywheel or motor said that it has two cables but i think it has 6
Good question, but if you look here then the answer is 5: ruclips.net/video/R5BHZe8gbcs/видео.htmlm10s See the ropes coming off the big sheave, down to the smaller wheel.
This is not normally required. But let's change the conditions: What if, it's summer time, it's really hot in the motor room, there is no air conditioning (there isn't in this room) and the lift is being used constantly. This is a condition where the motor might get too hot and then needs a fan to cool it down. So in summary, the fan is not required 99% of the time, but during hot conditions the fan is available for the 1% of the time when the motor gets hot.
+ShadowGuidR yep its a popular one. But the most popular is the year someone was born! I was always figuring out people's codes by looking at finger prints around the most commonly used keys.
Yeah I guess so. It also depends on which part of the relay you are touching. If its the armature (the bit the pushes the contacts) then this should be fine to press on any relay, but it's all about being careful, and best practice is to wear gloves or press the relay with something that doesn't conduct electricity.
Urgh, I know what you mean, I HATE water tanks too :( our plant room had 2 massive blue tanks I had to walk past when I had to check roof access hatch security, going up the roof access ladder if you were unfortunate to look behind you, you were staring straight into the belly of them. For this reason, I refuse to enter our car wash plant room as its all water tanks, filters and a noisy compressor that makes you drop the kids off when it kicks in .. urgh...
+JohnnyX50 OMG that gives me the frighteners - "if you were unfortunate to look behind you, you were staring straight into the belly of them" - so there was no lid? It's actually the ball valve part that I'm afraid of, did this tank have this?
Here is a copy/paste from my "water tank phobia" video... ruclips.net/video/KD3IR3UyKWY/видео.html ...SO WHY??? It's not actually the tank of water I'm afraid of, it's the automatics (especially ball values) - it's a bit like a spider that's completely visible and STILL, but when you disturb the "web" (water) it starts moving and hissing as water enters the tank. Ok, so a urinal is different, but in a way it's worse! You can hear it, water dripping into a tank which you know will 'erupt' without warning - it's just when? Is the tank full or empty? The dripping varies in pitch and volume. In fact, the fuller the tank, less distance for the drips to fall and the volume reduces. This gives you a false sense of security, as you take your mind away from it. But then, when you least expect it... The water starts falling down the pipe and you realise the flush has already started - too late to escape. From a quiet room the noise is too loud and you can hear the whoosing and gurgling of what's going on in the tank, as if the tank wants to let you know. Panic sets in, but I cannot bear the situation and it's too late to escape so I try and create a "mask". Eyes tightly shut, hands pressed hard against my ears, keep moving them to create a rustling noise to prevent me hearing the room at all. When I'm sure, I release my ears and the situation has ended. But the dripping is now louder than before as the drips travel further into the tank - a warning from the tank to 'GET OUT'. I run out trying to plan every step, including pulling the door handle down and opening the door at the same time as I'm moving towards it. Outside the room I casually walk away, but with my heart beating out of my chest! YES, I HAVE A FEAR OF WATER TANKS!
A STALLION?? REALLY??? Hmmm. I'll have to think about that one. So will Mr. Chay if he ever gets a whiff of it. Waiting on the next one and you can branch out in to safe cracking any time!
+Rossis Eisenbahn Videos Hi thanks for your comment. Sorry I'm not sure if I understand your question? I've been in lots of motor rooms... is this the same as what you mean by engine compartment?
As described in the follow up video.... ruclips.net/video/R5BHZe8gbcs/видео.html Yep, used to love trying to work out codes! People picked the same ones, or they were very similar. I'd like to add a few more people used to use... 2468, 19XX (someone's date of birth, look at the finger prints to work out the last two numbers haha), 1066 for the battle of hastings, and a whole load more!
What type of elevator is this? It's not a true "single-speed" traction elevator because you can see (and hear) the motor change into what sounds like a lower mode a second or two before the lift stops. is there a more proper name for this? "Two-speed"? haha
Sorry for jumping into a conversation that is not mine but. that lock is mechanical, so if you know the digits of the code and put them in, in any order it will unlock.
Perhaps you should think of joining the elevator union here in Canada 🇨🇦 I am elevator mechanic from new generation I work on I O PCB boards anyhow I am surprised there was no machine guarding here it is law in case such people like you and general public make their way in the machine room also it is law to have car top railing anyhow nice video but be careful shock electrical can kill you
Thanks for the message. I did go for a job with Express Lifts straight out of school (1988!) but decided to follow a different industry. I'm an engineer myself (not with lifts) and well aware of what I can and cannot touch. All my videos containing motor rooms have that exact warning at the start. Yes, this motor has escaped the guards - very surprised to see it like this!
+David Irwin (passacaglia28) By the way, thanks for the comments! Well, it was kind of a "reminder" to everyone that lift surfing could cost you your life. It would seem that some people are treating lift rooftops as playgrounds - I'm telling you - IT'S ONLY A MATTER OF TIME
Trust me, I totally believe you. I would never dream of attempting to surf atop any elevator. However, because of yours and others' You Tube channels devoted to vintage "lifts", I am now very interested in learning more about them. Last week, I wandered into a parking garage near my house in search of the elevators, just because I was curious about the manufacturer, and what kind they were. Thank you, Mr. Matt, and thank you Beno! It turns out they are both Otis, gen... I have no idea, and probably modernized a bit, but there was nothing very special about them. And there were HYDRAULIC!!!! Bummer! The good new is, I rode one to the roof parking level to discover one of the city's disaster sirens atop a stairwell tower, vestibule... thing. That was awesome! I even took a photo with my phone. ANYWAY!!! Thanks for your replies. Cheers from across the pond.
+Roger Hammond Thanks! haha. Well I knew exactly what those relays did since my visit to that hotel in Saudi Arabia (I used a cigarette butt then!!) ruclips.net/video/nuAb2rTmJoE/видео.html see 8:06 lol
+Angel Monica Yep, but when you are actually in these situations sometimes when you leave you get these bright ideas, but tooooo laaaate! I've been in this situation a few times and had to revisit the place. This place is far from me, but maybe next time I'll go back for another visit
I cannot get over the cleanliness of that equipment. Even the relays and contactors look squeaky clean!
2:28 - pro tip: with these mechanical locks that require a code, it typically doesn't matter which order the numbers are entered, so if you see 4 buttons that stand out then there are 24 possible combinations of those 4 digits, plus the fact each number can only be used in a code once... you get the idea, these things are super easy to defeat.

There are actually 10,626 combinations of four numbers from twenty four without any repetitions. Might take a bit longer then.

Hi I find the concrete platforms where the lifts motor+gear assembly sits on (with the holes for the cables) often look as if they could crumble/break. Could that happen and wouldn't the lift fall down ?
They are pressed on it and have a tooth. They won't come off easy and don't roll uncontrolled.
I hate boilers and water tanks too, what was the piano music that played at the start?
It’s just you 😂 Great vid btw 😊
Thanks Neil :)
Water tanks and high voltage terminals only 5 feet apart, what could go wrong !
When you press the relays to select different floors, does the light inside the button light up to? Or does it just go there without that?
Pressing the button places voltage to make the relay switch on. When the relay is on, this places a by-pass across the button, so effectively the button can be released whilst the relay puts a short circuit across it - this is a what a latching relay does.

+mrmattandmrchay No, it's a video from a famous lift mechanic in Kiev, I found it in my subscriptions.
I love the EEEEEOOOWWW sound the motor makes when it slows down then the sound of the clunking relays and motor contactor(s).
When the lift is approaching a floor, how does the motor speed control work on a lift that is all relay logic. I didn't see any variable frequency drive (VFD) controller.

6:36 I was wondering how many cables this lift has, 3? 4? 6? 8? [Motor stops] Motor or flywheel: TWOHHHH Okay the flywheel or motor said that it has two cables but i think it has 6
Good question, but if you look here then the answer is 5: ruclips.net/video/R5BHZe8gbcs/видео.htmlm10s See the ropes coming off the big sheave, down to the smaller wheel.
why is the moter fan cooled ?
This is not normally required. But let's change the conditions: What if, it's summer time, it's really hot in the motor room, there is no air conditioning (there isn't in this room) and the lift is being used constantly. This is a condition where the motor might get too hot and then needs a fan to cool it down.
So in summary, the fan is not required 99% of the time, but during hot conditions the fan is available for the 1% of the time when the motor gets hot.
I have seen 1066 as entrance to blocks of flats a few times. :/
+ShadowGuidR yep its a popular one. But the most popular is the year someone was born! I was always figuring out people's codes by looking at finger prints around the most commonly used keys.
what is the code to motor room? or you safety rule KEEP OUT?
HAHA IT'S CODE C098765!!!
Well C567890

This lock is a Zone brand
Can you wear leather or rubber gloves to press the relays?
Yeah I guess so. It also depends on which part of the relay you are touching. If its the armature (the bit the pushes the contacts) then this should be fine to press on any relay, but it's all about being careful, and best practice is to wear gloves or press the relay with something that doesn't conduct electricity.
0:34 What The??
Urgh, I know what you mean, I HATE water tanks too :( our plant room had 2 massive blue tanks I had to walk past when I had to check roof access hatch security, going up the roof access ladder if you were unfortunate to look behind you, you were staring straight into the belly of them. For this reason, I refuse to enter our car wash plant room as its all water tanks, filters and a noisy compressor that makes you drop the kids off when it kicks in .. urgh...
+JohnnyX50 OMG that gives me the frighteners - "if you were unfortunate to look behind you, you were staring straight into the belly of them" - so there was no lid? It's actually the ball valve part that I'm afraid of, did this tank have this?
What is it that scares you about the water tanks?
Here is a copy/paste from my "water tank phobia" video... ruclips.net/video/KD3IR3UyKWY/видео.html ...SO WHY??? It's not actually the tank of water I'm afraid of, it's the automatics (especially ball values) - it's a bit like a spider that's completely visible and STILL, but when you disturb the "web" (water) it starts moving and hissing as water enters the tank.
Ok, so a urinal is different, but in a way it's worse! You can hear it, water dripping into a tank which you know will 'erupt' without warning - it's just when? Is the tank full or empty?
The dripping varies in pitch and volume. In fact, the fuller the tank, less distance for the drips to fall and the volume reduces. This gives you a false sense of security, as you take your mind away from it. But then, when you least expect it...
The water starts falling down the pipe and you realise the flush has already started - too late to escape. From a quiet room the noise is too loud and you can hear the whoosing and gurgling of what's going on in the tank, as if the tank wants to let you know.
Panic sets in, but I cannot bear the situation and it's too late to escape so I try and create a "mask". Eyes tightly shut, hands pressed hard against my ears, keep moving them to create a rustling noise to prevent me hearing the room at all.
When I'm sure, I release my ears and the situation has ended. But the dripping is now louder than before as the drips travel further into the tank - a warning from the tank to 'GET OUT'.
I run out trying to plan every step, including pulling the door handle down and opening the door at the same time as I'm moving towards it.
Outside the room I casually walk away, but with my heart beating out of my chest!
YES, I HAVE A FEAR OF WATER TANKS!
A STALLION?? REALLY??? Hmmm. I'll have to think about that one. So will Mr. Chay if he ever gets a whiff of it. Waiting on the next one and you can branch out in to safe cracking any time!
+Lewie McNeely It was the best analogy (and the funniest one) that I could think of lol
Too many relay fumes for you, Pal.
Were you actually ever gets when you went purely in an engine compartment? (Sorry for my English)
+Rossis Eisenbahn Videos Hi thanks for your comment. Sorry I'm not sure if I understand your question? I've been in lots of motor rooms... is this the same as what you mean by engine compartment?
He probably meant: Have you ever been caught in a motor room?
You can touch the relais with your fingers😉
It would be the last thing you touch. Some of those relay contacts have 415V on them.
most commonly used codes:
1234
4321
the same number four times
2580
1397
0582
many more
Why? Because they are the easiest to remember!
As described in the follow up video....
ruclips.net/video/R5BHZe8gbcs/видео.html
Yep, used to love trying to work out codes! People picked the same ones, or they were very similar. I'd like to add a few more people used to use... 2468, 19XX (someone's date of birth, look at the finger prints to work out the last two numbers haha), 1066 for the battle of hastings, and a whole load more!
What is the code?!
Nice vid :D
Motor sound great
Yeah I agree... first time it started was a nice sound!
What type of elevator is this? It's not a true "single-speed" traction elevator because you can see (and hear) the motor change into what sounds like a lower mode a second or two before the lift stops. is there a more proper name for this? "Two-speed"? haha
4:12 no its not just you such big as things scare the shit out off me
whats the song you used for the warning in the beginning?
The Videosmith Otis MacDonald not for noting
Sorry, missed this message! Eureka by Huma-Huma - find it in the youtube audio library.
Kristofs Haus this is not a video of song this is a video of lift motor room
mrmattandmrchay,i like this motor room,it is putafole and,i like that sounds of the motor! B-D
today's elevator controllers have low-voltage computer circuits.. but high voltage AC motors
The controller controls contactor's that energise the motor.
Press some more relays!
+diamondcraftia Only the call button relays. I really don't want to take this out of service, else I have to walk down 7 flights of stairs :D
Sorry for jumping into a conversation that is not mine but. that lock is mechanical, so if you know the digits of the code and put them in, in any order it will unlock.
Critter You have a point
+1
did you "ask" before going up there?
+Sam's Lab what do you think the answer would be? :)
Perhaps you should think of joining the elevator union here in Canada 🇨🇦 I am elevator mechanic from new generation I work on I O PCB boards anyhow I am surprised there was no machine guarding here it is law in case such people like you and general public make their way in the machine room also it is law to have car top railing anyhow nice video but be careful shock electrical can kill you
Thanks for the message. I did go for a job with Express Lifts straight out of school (1988!) but decided to follow a different industry. I'm an engineer myself (not with lifts) and well aware of what I can and cannot touch. All my videos containing motor rooms have that exact warning at the start. Yes, this motor has escaped the guards - very surprised to see it like this!
This motor uses rheostats to slow down dynamically
INVERTED LIFT MOTOR ROOM SO AMAZING AND INVENETER 99,99,99 MILES PER HOUR!!!!!
You've got a beautiful British accent * . *
+IDlevels thanks :)
Nice vid XD
+Adam Sang Thanks Adam :)
+mrmattandmrchay
nnnnnnnnn
Thirdly: did I detect a warning to Beno to not surf this lift? Lol!
+David Irwin (passacaglia28) By the way, thanks for the comments! Well, it was kind of a "reminder" to everyone that lift surfing could cost you your life. It would seem that some people are treating lift rooftops as playgrounds - I'm telling you - IT'S ONLY A MATTER OF TIME
Trust me, I totally believe you. I would never dream of attempting to surf atop any elevator. However, because of yours and others' You Tube channels devoted to vintage "lifts", I am now very interested in learning more about them.
Last week, I wandered into a parking garage near my house in search of the elevators, just because I was curious about the manufacturer, and what kind they were. Thank you, Mr. Matt, and thank you Beno! It turns out they are both Otis, gen... I have no idea, and probably modernized a bit, but there was nothing very special about them. And there were HYDRAULIC!!!! Bummer! The good new is, I rode one to the roof parking level to discover one of the city's disaster sirens atop a stairwell tower, vestibule... thing. That was awesome! I even took a photo with my phone.
ANYWAY!!! Thanks for your replies. Cheers from across the pond.
4:30 Ohhh german!
Jan Hendrik Franke oh I see
I found that part scary
What happens if you're caught trespassing? Jail?
+Alex Danco Depends who catches you. No not jail but booted out of the building for sure!
And never allowed back in.
I want you upload, 1 video for logic elevator 4 floor, please my wait your video, tanks
Ha Ha nice bro .. 😅 👍 Liked the don't do what I do do what I say thing u did before manually hitting those relays ..
+Roger Hammond Thanks! haha. Well I knew exactly what those relays did since my visit to that hotel in Saudi Arabia (I used a cigarette butt then!!) ruclips.net/video/nuAb2rTmJoE/видео.html see 8:06 lol
Whats with the fear of water tanks?
+npadul30 ruclips.net/video/LBzik-XthE4/видео.html see 3:18
u could of turned the shaft lights on
+Angel Monica Yep, but when you are actually in these situations sometimes when you leave you get these bright ideas, but tooooo laaaate! I've been in this situation a few times and had to revisit the place. This place is far from me, but maybe next time I'll go back for another visit
i know it just thorght to say it so next time u go back to a shaft engen room u'll no :0
