[@claytonno2571]

@@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.

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.

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

[@brettowen6773]

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 KZbin of elevators crashing into the ceiling rather than the ground.

[@tundefodor5684]

this is why safety gear car work on both direction, plus unettanded car move ment...

[@psdaengr911]

I worked for the Otis Elevator Company. The engineering name for the Otis "traction elevator" is "geared electric traction" elevator. The gear drive design permits the elevator motor to rest under normal conditions without a separate brake locking the pulley when the car is stationary. So it has two safety mechanisms to prevent slipping/falling, one rarely needed. The difference between traction and hydraulic motivation is traction pulls while hydraulic pushes.

[@pieterlierman1829]

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.

[@ejgrant5191]

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.

[@fischermarius2586]

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.

[@DJSpinSter2004]

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.

[@joeyager8479]

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.

[@Lacronh]

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?

[@joeyager8479]

@@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.

[@Lacronh]

@@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?

[@joeyager8479]

@@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.

[@BryceWalker30]

Why does they do that little drop thing when they come to a stop. It’s like it misses alignment and then corrects but they all seem to do it. Is it the two doors connecting?

[@MyNotSoHumbleOpinion]

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.

[@mattheww3116]

Interesting

[@markdoble736]

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.

[@CentralPALocos]

This video was incredibly informative. I recently started working at a feed mill, which in this instance is a tall slip construction concrete structure that tops out around 200’. Most of the work we do is on the lower floors, but there’s large internal bins that take up a large space inside the building, and then there’s a few floors at the top to access the tops of the bins as well as augers and turnheads. To get to the top, and to move heavy objects around we have a beat up old elevator. I heard rumors that it was taken from a building in New York, although I can’t be certain of that. Either way, I’ve poked around the control room, and looked down the hoist way trying to understand how it works. Your video perfectly explains the mechanisms behind how ours works. One thing I didn’t know was the overspeed governor, I’ve seen it but had no idea what it could be used for, but now I know.

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.

[@sgtscheetje]

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...

@@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!

[@shinyagumon7015]

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.

[@DrWhom]

yep, wikipedia is your friend

[@tylerotis6209]

Yup, same Mr Otis. He founded the company and eventually sold it, I believe.

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

[@JaredOwen]

Yikes! I'm glad you got out

[@apollogaming2781]

@@JaredOwen i would also love to know why isn't there any escape hatch in the ceiling of a elevator

[@DrWhom]

@@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

[@leave-a-comment-at-the-door]

​@@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.

[@liamdiedericks5846]

@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.

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

[@Lacronh]

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.

[@ocsrc]

@@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

[@Lacronh]

@@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?

[@ocsrc]

@@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

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

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.
