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.
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
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.
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.
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 opt is VERY tricky to do that! Edit: fixed grammatical issues as well as spellings
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.
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.
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
Yo real quick, how would u describe how an elevator closes in dialogue form? Need it for my momma not me. Ps. Reword is 20 coupons to a bouncy house in Nantucket. Biggest bouncy house in the northwest. lol

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
I am a engineer so here's a few ideas: - Piston Elevator - Boat elevator - Water elevator - Trapdoor elevator - Minecarts - Command blocks - TNT - Firework
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!
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**
