📼Video Summary:
The elevator (or lift) has been around for almost 2000 years now. Elisha Otis invented a safety mechanism in the 1850s that allowed for widespread use. After that, elevators because the core of most buildings. Hydraulic Elevators use a cylinder and a piston to push the cab up from underneath. Traction Elevators have a motor that pulls the elevator up using cables. The Door Operator opens both doors - the Cab Door and Hoistway Door. The Interlock is the mechanism that ensures that the Hoistway Door does not open until the cab is right behind it.

I hope you found this video uplifting! Thanks for watching😎 (and putting up with corny jokes)
Cool
Hey jared 7 seconds!!
I love it! You rule Jared!
Did not know that
Sir big fan pls reply.....
I worked for an elevator company for 13 years, an excellent video, thank you for the time and effort you put into it.
Awesome! Glad you enjoyed the video
Let's upvoted this comment, so it can be elevated to the top!
No other job has more ups and downs.
awesome video indeed! btw, i was wondering if the hoistway door could be opened if someone try to do so exactly when the elevator is passing behind heading to another floor
@julianleite
Before opening any door with a key the elevator has to be locked off first.
Absolutely outstanding. No other animations on YT come close to this dude's work.
Animagraffs is pretty good. Mustard too.
Yep it takes months to make these 3D animations
Lesics
Thanks Labrador!
@@_Kona__ love both
I knew elevators had some sort of a safety mechanism to stop the the cabin from falling, in case the cables snapped. But having watched your explanation of how it actually works, I feel a lot safer riding elevators! Thanks for putting all this hard work into educating us, @JaredOwen
I feel a lot safer too
This looks like a dangerous machine if cables snap but it is not what you think
I mean it wasn't what we thought.
@@hercegovac9999 why do I keep seeing people with this weird anti lgbt emoji
oddly i feel less safe, feels like the emergency break wont stop it that fast :d
Retired from the elevator industry about 10 years ago. You paint a thorough picture of how an overhead traction elevator works along with introducing correct terminology for its components. Great job.
As a huge fan of 3D, I can't help but notice the Blender easter eggs on the building. The modelling and animation in this video is stellar!
Thanks Ken!
What easter eggs did you notice?
lol, yeah. I saw that instantly xD
Same
@@MISHBASH 2:30 , blender logo, bottom right of the building
From VCRs to elevators, and to space vehicles. You must have gained such an incredible amount of knowledge doing all the animations that you have done over the years.
I had been a building mechanical equipment consultant for nearly 30 years. Working with different types of elevators like hydraulic and traction type. I’m glad you (@Jared Owen) has shared this enlighthening video. This enhances the elevator riding public to understand how safe and the mechanism envolved in an elevator. ❤
As a kid, I had these "How Things Work" books that will show a diagram of everyday objects and their internal mechanisms. I'd spend hours just imagining them from the static pictures on the books. Jared's videos tickle that same part of my brain as an adult.
Was it the book with all the mammoths? They released an updated version, _The Way Things Work NOW,_ a few years ago. Still as enjoyable a read as I remember it being 👍
Bro I had that book too.
im 14 not a lot of people still read those books where i live there is a elevator and i always wonder how the work
The great thing about these videos is the animations are simple enough that you can see what's going on, but complex enough that you don't miss out on all the details. It's like the perfect middle ground. Great work as always!
Thank you blenderTimer!
Agreed
I work on elevators everyday and this video is spot on with great info! All the essentials to get the basics and some advanced knowledge. We sometimes call the counter weight "THE WIDOW MAKER". Picture working in a unlit hoistway on top of a elevator cab 100ft up and a gigantic block of metal goes zooming by and all you hear is the whoosh of the wind.
Jared, your Gift is your Ability to shed light on things we don't even think about... and you do it in a Pleasent, fun and entertaining way... not to mention your Computer animations are great
Been installing these for almost 20 years, everything explained here is spot on.
I m a elevator service technician but ive never seen a cylinder of hidraulic lift built underneath the cabin, ive seen only the cylinder beside the cabin connected with steel ropes to the floor of the cabin.
@@cpkora422 Well, as a elevator technician you should know this. There's two major types of hydraulic elevators that being "Holed" or conventional, and "hole-less" hydraulic elevators. Within that "hole-less" category there is 3 those being non telescopic/single stage, telescopic, and roped hydraulic elevators. Been a while since I studied them but, 60 feet is the max for "holed", 20feet for non telescopic, 50ft for telescopic, and 60ft for the roped hydraulic. With a "holed" you have to drill a massive hole as apposed to the roped hydraulic not requiring that extra step and still manages the 60ft that a "holed" can do. Id guess that is why you are used to seeing only roped hydraulic as its a pretty long job to redo a "holed" when it claps out. Stay safe.
You must work in an area where the ground cannot be drilled easily
The level of excitement I experienced before starting this video really demonstrates how well Jared does what he does. He does it so well I was genuinley excited to learn about how elevators work
I agree and he explains complex mechanisms in such an easy to understand way, that even when my child was 7 years old, he would watch and understand some of Jared's videos!
Thanks Bradley!
My son (7) is the same way with all of his videos! He is teaching me things now! And is obsessed with the Statue of Liberty and going to New York so thanks for that, too! 😂
@@JarahMikethat’s another thing I love about his videos. He teaches us about things that are in our everyday lives, and makes you appreciate those things. Like after his video on how pianos work, I was a lot more interested in my girlfriend’s dad’s grand piano, and it gave us something to talk about.
There's one additional safety measure in the event that the emergency brake doesn't work: a buffer (basically a large shock absorber) underneath the elevator cab and the counterweight. If the elevator doesn't stop before it reaches either the top or bottom of shaft, it'll impact the buffer and bring the elevator to a rough-but-not-life-threatening stop. So, you won't die from a freefall even if every other safety mechanism fails.
Side note -- you're also much more likely to "freefall" upwards rather than downwards if there aren't very many people on the elevator since the counterweight weighs more than an elevator with a few people. You can see videos on UA-cam of elevators crashing into the ceiling rather than the ground.
this is why safety gear car work on both direction, plus unettanded car move ment...
The effort you put in explaining this to us AND making incredibly clear animations is formidable!
As an experienced elevator mechanic, I’m thoroughly impressed with your examination here, very well done. Your terminology is pretty well spot on, and I also noticed that you modeled some components of off real equipment I work on. The machine is a carbon copy of an Otis gearless machine, the door operator looks exactly like a Montgomery EZ operator, and the door hardware looks like GAL stuff. Well done, 10/10.
Thanks David!
What an amazing teaching technique! You're not just a good motion designer, you're literally storyteller!
I really appreciate all of the animations and information you have shared with us and your 2:43 viewers. They are very well done and the information shared has taught me so much and I thank you much for that!
as a very well known elevator enthusiast, I find this video VERY informative! GREAT job!
I’m also an elevator enthusiast. I have watched your channel since I was 2 years old.
WOAH DIESELDUCY, I FOUND YOU
No Way You Found This Video.
😁
I used to be very scared that there would be a huge failure in an elevator while im in it. After watching this video, it has 99.9% eliminated my fear of elevators and im very happy!
Thank you very very much Jared! 😊
yes but elevators still fail. watch some elevator accidents many here in youtube
@@xaviertumblod8955 Regular stairs are many times more likely to kill you. 1,600 or so, vs maybe 15 worldwide on elevators, including places like China and Russia where they tamper w the shutoffs (many/most wouldn't happen if they were in place).
Yes, same here. After watching this I feel safer too, with the only exception of simply just getting stuck for a period of time due to my claustrophobia
on a per trip basis elevators are one of the safest forms of transpiration. there are MANY redundant safety features in software, electrical and physical hardware. I have been a elevator mechanic for 17 years now and pubic accidents are almost non existent in the USA. more often someone gets stuck in the elevator its from one of the many safety systems failing ( in a failsafe manor) causing the still perfectly safe elevator to stop. the worst part is just having to wait for help to get you out but even while stuck you are completely safe.
@@slappomatthewThank you for that comment. It's very helpful and informative.
I can't believe Jared bought 2 elevators and took them apart just for us! Amazing work!
As an Elevator Fan, this is definitely the coolest simulation I've ever seen! Good job!
Clear and simply straight forward explanation. Didn't know they were this safe.
I've retired from the elevator trade, you must have been talking to someone in the trade as you nailed all the terms and explanations correctly. Great work and thank you for not explaining in detail how the hall doors are opened by a trained tech in an emergency.
i was worried when he was mentioning the interlock and all that 😬
glad he did not elaborate on rescue operations
Why do you not want him explaining it?
@@RafaRadityo7 cause someone might create their own amateur key and try opening elevator doors for no reason and might cause an accident
In my entire life I wondered,"How does an elevator works? " And now this guy came into my life like a GOD to clarify my doubt WITH animation. Thank you so much for your animations and teaching. I learned a lot from you. Please keep uploading this kind of videos.
Thank you Madhav!
same, today youtube suddenly recommend this video just like it read my mind
I’ve been watching elevator videos for about a decade and none have gone into this much detail. I learned things I didn’t know
One of my hobbies used to be to go to the top of the world's tallest buildings (eg., Eiffel Tower, WTC, Funktum in Berlin, CN Tower Toronto, etc), so I've gotten to ride quite a few, and this was very interesting and informative. Thanks, Jared.
Great video. The world of elevators repair is a mysterious thing. I have been "breaking" into elevators for 32 years as a firefighter. I will share this with our Department. Thanks
You have a true gift for both animation AND explanation. Keep up the good work.
Thanks Darryl!
I stumbled upon your channel. I was reading about Mr Otis and wanted to know how exactly he performed the 'stunt" at the fair. I usually dont subscribe to channels unless they are outstanding or are different from what's trending on the social media platforms. Of course i whole heartedly clicked on subscribe. Thanks for the simple animation and the simple words you have used to explain the functioning of an evevator (or a lift, hehe!).
I frequently do social service by using my advanced degree in teaching school students in maths and science. I know how difficult it can get to convey even easy concepts in a simple manner so that everyone understands. Kudos to you for doing that.
You acknowledgment for MQ Elevators also shows that you are a generous human being who doesnt want any undue credit. I respect people like you. Content creators like you should be promoted and supported as i am pretty sure that you will enlighten everyone with similar knowledge which can be difficult to comprehend without the effective animation you did. You have earned a fan in me!!!! I look forward to more videos from you Jared.
4:43 The way you said "are you ready" made me feel so ready and eager to understand how elevators work. 😊 I feel like a little kid learning about new things. 😅
Are ya ready kids?
I work as a Building Manager and meet regularly with lift engineers and office executives. This video has definitely given me a clearer understanding of how an elevator works and will definitely help me in my role moving forward. Brilliant video and well done. Subbed and thumbs up given. Cheers mate 👍😊
I always love these videos. It really shows me how cool these inventions can be! I have always wondered how VCRs worked, and I am so glad you did one on that as it was mind-blowing how they designed it. Keep doing what you're doing!
My Dad worked on elevators for close to 40 years. It was a pretty interesting job fixing these up. He also worked on wheelchair lifts and dumbwaiters. He retired from working on elevators, and now he works as an elevator inspector
Wow, excellent explanation about the functioning of an elevator. Congratulations on this one. Just one small correction: you mention in your video that you need at least 4 traction ropes. With Flexisteel, a polymer-coated steel rope, this can be reduced to 3 ropes.
I'm a career firefighter and we often get called to elevator rescues. I'm familiar with how the drop key works to open the doors, but I've never seen elevators explained like this. Definitely very helpful, awesome job on the video!
And I thought all u did was get cats out of trees
I have been an elevator technician for 15 years. In my country ( Belgium ), traction elevators use 2 types of motors, with a reduction gearbox and gearless. In hydraulic lifts, the piston is positioned next to the lift and the lift cage is set up in a backpack.
In the past especially in the USA hydraulic elevators traditionally have the hydraulic cylinder buried in the ground below the elevator cab. The "side jack" elevators are kind of height restricted even with telescoping jack assemblies. The tallest hydraulic elevator I ever worked on was 8 landings about 30 Meters in height. Had to have coolers for the hydraulic fluid to keep tempratues stable. There are also roped hydraulic lifts in New York that go horizontally and allow a hydraulic method to work for over 10 stories....Most of these are pre-WWII buildings.
你好，我在中国湖南从事电梯技术员工作5年了，想请问一下你们待遇如何？
I knew that elevators had the inner and outer door but had no idea how they worked together with the latch and stuff. All the braking tech seems logical and simple and yet it is so important. Nicely done, Jared.
thank you so much for this video!!! love it!everything explained here is spot on. I am a translator (EN-CH)and I got a interpreting job consultation on elevator business ( didnt get the job for the price reason ). I started learning the mechanism from this video.
That amount of details you put in everything. This channel is a true gift 🥰
This video will help a lot of people to overcome their elevator fears
But only as long as it's an Otis elevator. Stay away from those Chinese made ones - those are guillotines.
@@SnoopyDoofie Kone elevators or Schindler are also among the best in the world
It should. Elevators are built to a high standard and IDK how many people even know this. You walk in and you can be assured you’ll be safe.
Wonderful video Jared and very nicely explained...Covers all the features and the safety mechanism as well in a simple and easy to understand format and is good for something seeking knowledge in operation of elevators
Wow, Jared. What an amazing work you do with those animations. Thank you!!!
This video is great! With your narration and your visuals makes learning easy and fun! Keep up the good work.
yea... i really enjoy watching Jared's new video because it's informative. also the 3D animation makes it even better.
Very well made video! I like the animations.
If you wanna go a bit deeper into hydraulic elevators, there’s three different hydraulic elevators: - inground (which you covered), holeless, and roped. Holeless hydros have their pistons and cylinders on the side somewhere instead of underground, and roped hydros are the same but there are cables holding up the elevator instead of the piston itself. Because of its usage of cables, it needs the overspeed governor like a traction elevator.
Also a small correction although this doesn’t apply to every elevator, some elevators don’t completely stop before the doors open. Some elevators have “pre-doors” (premature door opening) or “classic leveling”. This is a term elevator enthusiasts like I use. On some elevators (like Kone’s elevators), if you look closely the elevator’s still leveling after the doors have begun to open. They’re usually not off-level enough for you to trip over the door track, so that’s not a huge concern, and that actually makes the overall ride slightly quicker.
My apartment elevator does basement to 18 floors and from what I saw there's a piston on the counterweight
Oh, that’s interesting.
I like this video because It's not to complicated and It's not too simple. It's a very short video that goes enough into detail to understand it pretty quickly. Thanks for making this video because I've always been curious on how it works.
It would be cool if you could do a deeper dive into buildings with multiple elevators, like the Empire State Building you've already done, or the Twin towers, going through and explaining how the multiple banks of elevators are laid out, why they did it the way they did, and some of the limitations, (like floors that are close to each other but hard to get between.)
Hi Jared, could you make an animation for the gateway arch? This video reminded me of the elevator/lift that we ride in to go up to the top of the arch when I visited
I like the idea😀
@@JaredOwen Jared I thought you was also going to explain how the elevator stops a specific floor
@@ClickNBuild that’s more to do with the programming of it no?
@@fhdang8978 Yes
@@JaredOwendunno if you're interested, but an explanation of the classic IBM selectric typewriter would be fascinating
you dont upload often, but when you do, its an amazing watch.
Agreed
Thank you!
I just took a one day elevator rescue course (industrial fire brigade) and you sir explained how elevators work much better! 👍
Your videos are AMAZING!!!! I'm a visual learner and there's NO way someone could explain all of this to me!!
You are literally a treasure for making so much good quality content.
Thank you!
i’ve always had a fear of elevators, now that i know the safety mechanism on elevators from this video, i regained some trust on elevators. I mostly like the elevators that are clear with a clear temper glass shaft, those make me feel most safe
Thanks Jared, for the clear explanation with animated video. Also liked the way you have segmented and organised the chapters for easy navigation. Good day. ❤
I never knew how many different components went into an elevator. Great video!
Pretty good! You did mention about the varying factors for sure, especially the door mechanisms are quite unique from one lift to an another
As in, the real concept probably remains the same, but they are implemented differently mechanically more so often. The one showed here at least to my knowledge was common in more older single doorlifts, dual door lifts are different
The video we all need! Thank you
I love this channel so much!!! Thanks for always giving us informative videos about random stuffs!
you are just amazing jared......you give a very simplified explanation and use amazing visuals to explain the inner workings of any machine......thank you so much for your videos and your efforts
Great video Jared. Before all of the safety features were worked out, the early days of elevators were pretty scary and fraught with nasty deaths. Btw, the Blender logo additions are a nice touch.
Please don’t leave any racist remarks. This is an educational channel.
@@GardenGuy1943 what?
Finalmente alguien agregó pistas de audio a los videos para que cada uno pueda escucharlo en su propio idioma sin tener que usar los subtítulos, que distraen bastante del contenido visual 👍
Super excited to see what you’re going to make next. You’ve covered the escalator now you covered the elevator. I’ll bet your video also explains how a dumbwaiter works. Similar to an elevator but smaller. Can wait to see what’s your next video gonna be, super excited.
My first engineering job was for an elevator company. I helped design elevators to customer specifications. I also did a lot of the custom designs. I did design work on hydraulic and traction passenger and freight elevators and also on escalators. This video does an excellent job of covering the basic design of elevators. The coolest thing was being out in the field and riding on top of the cab in a bank of 3 elevators while doing maintenance.
Wow, that would be quite something to ride on top of the elevator. Sit tight, don't move, and keep your hands close to yourself I guess. I also assume that at the top floor, there is plenty of space above the elevator.
Do the hydraulic ones have just as many safety mechanisms? And about the shaft, does the underground part of the shaft move, or is it a telescoping mechanism that emerges from the underground shaft to push the cab up?
@@Lacronh This is when the elevator is in service mode. It runs slower and is out of service to passengers. There is an operators station up there that requires both hands to hold buttons to operate. But you need to be extra careful with the counterweights and other elevator operating in the bank. There is a bit of distance (overhead) so that's not an issue.
With hydraulic elevators the cab basically sits on top of a piston the lifts it. For ascending a pump pumps oil into the bottom of the cylinder raising the elevator cab. The piston assembly is in a drilled and cased well hole that is about the same depth as the total elevator travel. Most hydros only serve 2-6 floors - usually a maximum of 60ft of travel.
There were some telescoping pistons, but the cost outweighs the benefit.
Hydros descend by opening a valve that controls the flow of oil to the reservoir and the weight of the elevator is the what's used for descents. Yes. there are also safeties, but even a complete failure of the oil lines still wouldn't allow it to freefall.
@@joeyager8479That's helpful to know. So regarding the hydraulic ones that don't telescope, the entire piston moves up and down in the cased well hole, thus lifting/lowering the cab. Correct?
@@Lacronh The cylinder body is suspended in the well hole. The well hole usually has a steel casing protecting the cylinder body from contact with the earth.
The piston rod extends or retracts to raise or lower the car. The piston travel is slightly longer than the total stroke. There is some overtravel built in at each end so the elevator never hits a hard stop.
It's been about 50 years since I worked on these and there are other designs that use cylinders that don't require well holes. Some actually attach the car to the cylinder piston with cables and pulleys. I'm not familiar with these designs.
cool
Good video as always! only a small addition: almost all hydraulic lifts have the piston above ground. this piston pushes a pulley which pulls wires connected to the ground and to the cab, just like in the forks of a forklift. This allows you to use very long pistons without having to dig deep holes underground. In Europe they are widely used in low houses because they can lift very heavy loads, require very little energy and space to operate (just a small oil compressor) and are very safe in the event of a blackout. In the event of a power failure they are able to go down to the floor below by themselves without leaving people stuck inside.
Interesting
They are known as indirect acting hydraulic lifts. The piston is only half the length of the total lift travel as the lift is roped 2:1 so the speed of the lift is also double that of the piston speed.
História, funcionamento e explicação técnica dos elevadores nos mínimos detalhes. Excelente trabalho e sem dúvidas o melhor vídeo sobre elevadores da Internet. Parabéns e que Deus te abençoe.
I have always been fascinated by elevators! And now I have learned things I did not yet know. Thanks!
I got trapped in an elevator for 2 hours one time, it got hot and ran out of oxygen! I also know why there’s no escape hatch in the ceiling unlike in Die Hard 2 for instance
Yikes! I'm glad you got out
@@JaredOwen i would also love to know why isn't there any escape hatch in the ceiling of a elevator
@@apollogaming2781 liability issues. people can get into all kinds of additional problems once they get up there in the shaft, and usually they are rescued before "the oxygen runs out" - btw, oxygen does not actually run out, but OP did experience the sense that this was happening, probably because carbon dioxide in the cab was building up
@@DrWhom Professional diver here; yes it is much more likely that there was a buildup of CO2 than oxygen running out. Your body actually has no way of reporting low levels of oxygen to your brain, the urge to breathe comes from high levels of CO2. Because CO2 is acidic, it is easy for your body to measure how acidic your blood currently is to tell you to take a breath. (This is why carbon monoxide is so dangerous; it displaces air & binds to your blood easier than oxygen & is not acidic, so it replaces the oxygen; and you pass out without noticing anything because your body is still getting rid of the CO2 just fine.) Essentially, if OP felt like they were running out of breath, that's CO2 buildup, and if they thought everything was fine and suddenly passed out, that's lack of oxygen.
@APOLLO GAMING27 There is a hatch but it can only be accessed from within the elevator shaft itself which is for rescue only. It won't open from inside the elevator because people shouldn't be inside the shaft, only maintenance and rescue teams.
Estupendo material, tengo entendido que los ascensores son el medio más seguro para desplazarse, incluso la gente sufre mucho más accidentes en las escaleras.
Hi Jared, we love your videos because you take the time to explain things in detail and at the same time separating the details into distinct parts.
Would you consider making a video explaining an EV?🤗
I am very grateful for this UA-cam. I read a book about elevators. But this UA-cam you made made me understand elevators.
Great video brother we need more videos will support u brother
One thing to note that you didn’t mention (I could be wrong here) is that one cable is strong enough to support the elevator car and the counterweight; the extras serve as backups in case one were to snap
Yeah that sounds correct to me!
Yes, the multiple hoist ropes do provide a safety function. But multiple hoist ropes are used to provide sufficient traction between the drive sheave groove and hoist ropes so the elevator can accelerate and decelerate at a decent rate.
Seriously this is the best channel I've ever found on youtube. I could watch stuffs like this all day
Wow
I came across one of your videos by chance and I am glad I did 😊
This is just amazing
I have been teaching engineering students for years. Your videos can be amazing resource to share with students. It's not just about the absolute quality of the animation, but it is about your beautiful smioth explanation.
Keep it up. I will have to go and watch all for your videos
Great video, really informative as always.
Also is this Mr. Otis the same one who founded the Otis Elevator Company?
If so then they did good work for these past centuries.
yep, wikipedia is your friend
Yup, same Mr Otis. He founded the company and eventually sold it, I believe.
in smaller buildings (maube just older elevator styles) , those hostway doors are just normal metal doors that hinge out and I would like to know how they lock and unlock
I believe they still have an interlock, it’s just designed a bit differently.
This is the best video on how a lift works. Flawless!
This is great! The interesting thing about this is that a new railway called the Elizabeth Line in London, uses elevators that go in a diagonal direction, like an escalator. I think you could explain how that could work.
7:36 - - overspeed governor - - 7:49 - - flyweights
7:03 - - emergency brake - - 8:16 - - elevator clamps
7:20 - - brake lever - - 7:27 - - auxiliary cable pulley
1:30 - - 1:45 - - *the mechanics of the old fashioned teeth system looks more reliable*
The teeth act as a “ratchet” system. With constant use those teeth would wear out and those tracks would have to be replaced quite often, and if maintenance is neglected that could turn into a huge safety problem. The fail systems on modern elevators are relatively maintenance free.
@@ajfavale8236 I think you may mistaken - - but can please answer:
(1) How would the teeth “wear out” if they’re only used if/when the cable breaks? (There would only be “constant use” if the cables broke constantly.)
(2) What does “quite often” mean? (Do you believe the cable would be breaking weekly? Monthly? Yearly?) Please explain?
(3) What “maintenance” are you talking about? That should not be “neglected”? Please explain?
(4) By “fail systems on modern elevators” - do you mean the one shown in this video? Or are you talking about something else? Please explain?
Thanks!
On older elevators, you can still find doorless cabs. The cab just has 3 walls, so if you touched the front surface while it's moving (don't!), it would slide on your fingers. That's quite dangerous, but very cheap.
You're right. These lifts have a movable threshold. If your foot gets stuck between this threshold and the wall, the elevator will stop immediately. When we were children (60 years ago) we played with these lifts: pressing all the buttons at the same time, putting our feet between the threshold and the wall. Sweet memories...
Love these animations. Who knew I’d be fascinated by the inner workings of an escalator!
*elevator. I make the mistake all the time too. 😅
I would like to add a couple of points that were missed in this amazing description of a lift, at the bottom of the pit there is bumpers and fitted in pits is a stop button (which can also be found with the car top controls on top of the cab) and some maybe most, have a feature called pre-doors or advanced door opening, this is an efficient way of travelling as the doors open before it has came to a halt therefore reducing the time taken to stop and open the doors.
i like the blender logo easter egg at 0:07
😀 only a few people have spotted it
I wondered what that was 😂
I didn't know elevators have safety mechanisms. I've never encountered an accident and elevators in movies always fall to the ground. Thanks for the great video as always.
You’ve seen it in the movies before but there’s less than one chance in a million that it’ll happen in real life, let alone on the elevator you’re in
They're not like that in all countries. Some places have very dangerous elevators.
But, in general, you're much more likely to die from being trapped in a stopped elevator, or sliced in half by movement of the cab when you climb in, than by the elevator falling to the ground.
Appreciation for the really hard work, effort and insane hours you put into this 👏👏
I am aspiring mechanical engineer and your videos just add curiosity more to my brain. Thank you very much for this.
We have taken advantage of so many things in this world, it's amazing to see how they actually work! I loved this video!
And how old a lot of it is.
Thanks Joy!
*ANYONE ELSE HAVE A FLASHBACK TO SIM TOWER?*
Yes
@@GLADOS241i was about to say:”ROBLOX!?!?!?” 😂
I watched your old and new videos, Jared! Thanks for the amazing content you make! You're the best!
After watching this video, I finally made a graph of the elevator installation in my house. Thank you for showing this video!
You teach better than 99% of teachers world wide.
I'm glad that almost all my teacher is among 1%.
6 stories was the limit because of water
In most cities the water reservoir was 6 or 7 stories above ground.
So buildings had water tanks at the top of roof
The maximum distance you can lift is listed to about 75 stories because the stress on the cable is so great massive cables would be required
So, for buildings over 60 stories they almost always have a " sky lobby "
The elevators from the ground to the sky lobby bring people up to the sky lobby
The elevators from the sky lobby to the upper floors are just for the upper floors
Are you saying that even today, 75 stories is the max for elevators? If so are you saying that in all buildings above 60 stories, you have to take two separate elevators to get to the top? I don't recall that being the case when I went to the top of the WTC in the 90's.
@@Lacronh most buildings have a limit. The WTC had a sky lobby because of the limit.
You had to switch elevators in the middle.
The counterweight and the size of the cable and the weight would be enormous
You can have just a single cable and when you look at Old Mines they have cables that are 1200 ft or 1500 ft that take the elevator down to the bottom.
It is just much better and safer to have a sky lobby
Personally I don't think it is a good idea to have a high rise building more than 20 stories
Overpopulation is the reason why we have to do it.
When you look at the world of the 1930s you see very few skyscrapers and most cities were only three-story buildings
@@ocsrcThanks for that explanation. So in your opinion, even though you can technically have an elevator that goes 75 stories up, you think it becomes less safe above 20 stories (despite all the redundant safety mechanisms)? Am I understanding you right?
@@Lacronh Yes. I lived in an 11 story building with 121 apartments and 2 elevators. We were all disabled. When there were power failures the elevators would lock out on the 1st floor despite having a backup generator.
Walking down the 11 stories took 30 minutes.
If there was an emergency like a fire we would not survive
@@ocsrc Wow!
This is the best explanation of the elvator overall , thanks for making this 👌
Your videos are creative and very easy to understand. Also your presentation is awesome. It seems that you have worked very hard for it. I appreciate your effort to provide so much knowledge for free. I wish you success in your work.❤❤❤
Great video as always.
One correction, don’t use the emergency call button. If you have cell reception call the non-emergency number for your police department; you want fire rescue.
The fire department should be the people to come and get you out. It also ensures the fire marshal follows up with the maintenance company for the elevators ongoing maintenance.
Also, the fire department will get you out faster. The call button goes to an alarm company dispatch. You get put in queue with other issues. They are not there to get you out quickly, they are there to minimize cost/damage to get you out and in the end, they will look to minimize any lack of historical proper maintenance that caused the elevator to stop working.
Parabéns excelente trabalho! Tudo explicado nos mínimos detalhes, e com imagens perfeitas. Falo do Brasil.
Informative video as always, thank you! Best part for me was that in all the offices I've worked at, I kept seeing OTIS. I assumed it's a brand name but now I know where it comes from - a nice piece of trivia knowledge I could share next time I ride an elevator with some friends haha
I just found out ur videos, they r too intimidating that I can’t stop watching more and more. Great work
