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 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 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
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
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 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
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.

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.
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.
They just can't get that ''Tower Of Babel'' shape, desiore, & design out of their nature can they? This too shall one day fall. -former sgt. 82nd abn. 92618

@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.
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!
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**
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.
Service floors:-

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!

DominusZak yep, this video gives me anxiety
Stupid

i have actual nightmares about being in high speed elevators, thinking about tall buildings makes my skin crawl.
Same id just take the stairs I don’t care how long it takes lol.

I would hate to do Maintenance on that thing. Check every door.

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
2:23 that is terrifying to even watch
Glad I wasn't the only one to think that.
As tall as that building is the rooms inside of it must be tiny
2:23 Oh, dear. Hope nobody was in that elevator...

We can make the elevator go faster if we make them uncomfortable.
Those are HUGE elevator motors, with more cables than conventional elevators!
Those elevators should've used KONE UltraRope instead of conventional steel rope!!
Nice set of elevators!! Now just think about the antenna-guys on top of the whole thing hahaha
Well, that escalated quickly.
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
another thing with fast decline it makes you feel like youre free falling and any second you will crash with the floor.
As I understand it, long elevators are more like a skip in a mine headframe than an elevator in an ordinary house.
Nice video of the day.❤🎉. 0:38 .
That 100-ton gearless traction machine is for the freight elevator that serves from the Concourse to 138 Fl.
Vanity, vanity, vanity.
This is definitely john Lithgow talking.
I’m about to faint just by watching this 😩😭 my biggest fear

KONE Elevators have developed the Ultrarope....buildings up to 1000m. That's why they are the number 1 innovative elevator company!
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.
Who is the narrator for this it feels like I hear him every where

Is the narrator John Lithgow? Lol 😂
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
Get dem KONEs, No machine room required.
AviaRyanA330 Kone Minispace high rise lifts use also machine-room , you can't set an machine-room less lift in an skyscraper like that...
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
3:49 that sounded like a Ecodisc Clunk?

I have an insane fear of heights, and I don’t even think I can get past the 4th floor frfr
How to go higher?
STAIRS! :D
anyone know the music that starts playing at 4:11?
Yea the governor will stop it or if that snaps there breaks on the elevator cart
@youoyyoyou It is required on qa construction site or in service occupations. such as that elevator person.
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.
KONE UltraRope wasn't even invented yet.
The do that in both the fastest Taipei 101/ Burj Khalifa express elevators to the observation deck.

ThyssenKrupp has a solution by using magnet technology instead of ropes
I can see a horror movie. The 800 + meter elevator ride of death
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.
I am a engineer so here's a few ideas:
- Piston Elevator
- Boat elevator
- Water elevator
- Trapdoor elevator
- Minecarts
- Command blocks
- TNT
- Firework
The cable turn too much ....... This affect the tensionning of the main ropes :)
Fabulous.
Would an electro magnetic elevator with no cable work?
I'm surprised they used 1 to 1 roping systems

A linear motor is future here.
There would not be enough sheer power to efficiently power the elevator. The motor would burn out.
