To avoid confusion, you have to know: 8 meters per second is the speed of the highest rising elevator in this building serving from floors C to 138 10 meters per second is applied in both directions for the observation deck/sky lobby elevators. Service floors:- C and 123 ( Lower deck ) and G and 124 ( Upper deck )
I heard somewhere that the main buildings of the World Trade Center in New York City had almost 100 elevators each before they were destroyed that fateful Tuesday morning on September 11, 2001.
OTIS is a good choice. Thyssenkrupp also has experience in high rise elevators from the Freedom Tower and KONE modernized the elevators at the Sky Tower.
I once got stuck in the elavator at Beijing! And then on december 2013, I got stuck in the elavator at Paris! Make it two! Never wanted to ride it again but sometimes it's a must. Sigh. I am a malaysian and i never got stuck in any elavator in malaysia before
The burj khalifa has top of the line safety features, the concrete has a fire resistant coating as well as a sprinkler system throughout the building, no fire could bring this building down as it is a rock solid concrete structure. In the unlikely event all the stairwells were blocked there are refuge rooms and balconys where people could get airlifted to safety.
Actually, except for other towers, Burj khalifa the world's tallest structure is equipped with 38 fire resistant emergency evacuation lifts that operate during incidents of fire. People needn't use stairs to evaluate. The building planning is the best of this century.
I would guess that this lift has double wrap traction. You will see 20 ropes on the sheave but each rope passes around a secondary sheave and then back to a second pass. That’s really only 10 ropes. Still quite a lot compared to most “ordinary” lifts.
I remember watching this video 6 or 8 (possibly up to 10) years ago. It's still impressive, but as several other buildings have reached 2,000 feet in height, it doesn't wow me quite as much as it did years ago.
Was lucky enough to ride the Toronto CN tower observation elevator. my mother kept freaking out while I was too busy with my face up against the transparent elevator glass. Almost as awsome as riding the Jasper Sky Tram in the Rocky Mountains. Always loved being up high and my dream home is a penthouse on to of a tall building or high on the side of a ravine
3:41 CRAZY! They go so fast, yet can go so slow! The motor must be spining so slow. Example: suppose you have a motor that spins 10,000 rpm. When you want to spin it slow say 10rpm you run into problems, the motor would not have enough torque at so little voltage or frequency (deciding on motor type; DC or AC), you need a closed loop feedback, if the speed is going below what we want it would speed up and if it is too fast it will slow down, but still is VERY tricky to do that! Edit: fixed grammatical issues as well as spellings
Remember lifts are direct drive and a high speed lift will have a motor that is not even geared to the traction sheave. These machines are essentially just a very big powerful motor. They need to have the torque to drive a load away from a standstill and are designed to do just that. If you’re used to seeing electric motors running at thousands of rpm, you have to realise that these are very very different
@@caroleast9636 I totally agree these motors have VERY high torque, but what I meant is it is like driving a car that is in 5th gear and wanting to go 1mph, you just can’t do that very easily. If you see I said “Example: suppose…” that means it is an example
Shaw, it's 20 years now I've been a minister's wife. And I've been quiet, supportive, unobtrusive and after 20 years I still think you're a wonderful, a wonderful preacher. You can lift a congregation up so high they have to look down to see heaven. But it's the one to one where you need a little work.
The animation was wrong because the cable is tensed the highest at the pulley and therefore would break close to the pulley, the smallest tension is at the point of a cabin connection since it's the only of two points of the cable with zero weight added by the cable, other being the counterweight connection

I guess if more viewers give it a thumbup, youtube will recommend it to other viewers. Also sharing it on facebook and twitter will bring up its rating too.
Why dont they just install KONE? It uses the UltraRope, the first carbon fiber rope, if it rise higher, the cables will get lighter and been tested under the most extreme conditions.
To anyone saying *"INSTALL A KONE ULTRAROPE"* well if you were to safety break/Emergency stop the lift, it'll bounce and cause friction. Its hard for elevator -surfers- inspectors **cough** **cough**

Did you know that in the USA they wanted a building with 1001 floors and the numbers on this elevator are G to 1000 and it has space for 602 elevators that is a brand new building and the name of this building is The USA Building. It's the new tallest building in the world!

@youoyyoyou This building is in the Arabic world. It is very unlikely that the Muslim extremists would attack another Muslim country. If they do, they will lose support among all other Muslims in the world. Unless the Christian extremists launch the next Crusade against the Muslims, the building would not become a target. Timothy McVeigh was a Christian and he attacked his own country. So anything is possible. Unlikely but not impossible.
They need to make elevator's have on board Linear Induction motors like Maglev trains while climbing up on a worm gear and rack system and getting it's power from a 3rd rail or Pantograph/electric wire similar to subway train. There would be a back up battery with computer that locks the brakes once power loss in the main electrical system is detected thus preventing an elevator from falling. That will get rid of heavy cables and motors at the top of the building.
I would design the brakes to be engaged by mechanical springs. The brakes must be released by power. During a power loss, the brakes engage by themselves.
To avoid confusion, you have to know:
8 meters per second is the speed of the highest rising elevator in this building serving from floors C to 138
10 meters per second is applied in both directions for the observation deck/sky lobby elevators.

dunno why im getting so excited about elevators, but they're beautifully engineered machines
you know, if the cables broke, the elevator would stop. Otis himself invented a safety lock to market the first elevators.
Highly unlikely even one cable would break.
jb0177
Correct, they are very strong.
Elisha Grave Otis even showed in asterix cleopatra movie
wow
No the elevator would fall to the ground hard and that is dangerous
57 elevators!! In one building!

I counted the cables on the elevator machine and I noticed that there were 20 of them. That’s a lot of cables!

it's not too much if a stress if the elvator doesn't serve every floor but rather only the entrance/exit and observatory floors

anyone else see the slight roll back when the 100 ton guy first started moving?
Tom cruise don't need no elevator, he just run down the side :)
Those are HUGE elevator motors, with more cables than conventional elevators!
2:23 Oh, dear. Hope nobody was in that elevator...
That is a animation
That 100-ton gearless traction machine is for the freight elevator that serves from the Concourse to 138 Fl.
We can make the elevator go faster if we make them uncomfortable.
2:23 that is terrifying to even watch
Glad I wasn't the only one to think that.
Well, that escalated quickly.

It is John Lithgow.
Bro, I should of scrolled down the comment section because I just posted that question, and it was driving me crazy, John Lithgow.
The "elevator[s] of tomorrow" may be ThyssenKrupp Multi elevators: they do not require any cables, and just have magnetic rails.
Real Star Trek Turbolift technology
I agree

Would an electro magnetic elevator with no cable work?
"The urge to go tall, relies on the Burj"
Vanity, vanity, vanity.

KONE UltraRope wasn't even invented yet.
That building have already newer elevator that elevator on the video are the old ones
I have an insane fear of heights, and I don’t even think I can get past the 4th floor frfr

What would happen if there was a fire in this building?
I was thinking can elevator be made without cables...so the engine will be on the top of cabin and powering is by side track...like we know in metro.
iannickCZ It would need a long cable for power supply though
Yea the governor will stop it or if that snaps there breaks on the elevator cart
KONE Elevators have developed the Ultrarope....buildings up to 1000m. That's why they are the number 1 innovative elevator company!
Nice video of the day.❤🎉. 0:38 .
Elevator cable is excess design theory, where the cable is designed to hold more weight than the car can possibly generate by itself.
I don't know why they don't/won't/can't make an elevator to run on magnetic rails, like they have for high speed trains.
thyssenkrupp are doing it.
But one of the elevators only goes up to G to 127
ThyssenKrupp has a solution by using magnet technology instead of ropes
An ecodisc would die after a year with that performance, believe me, i work with ecodiscs. And btw, its otis...
And if this was a Generic, It would pretty much break the second it starts moving
