  • that's definitely an upwards crash. I had this to happen in an apartment building I used to live in a few years ago. Luckily, I was able to get off before it actually happened.

  • thank god they made it out

  • those 2 were lucky

  • I remember I saw this on another video.Something happened with the breaks.Just so you know the elevator door opens a little that's when things get crazy.

  • Huub Stapel, I remember him. 'I just read on wikipedia he still acting in German "Krimis".

  • Where is Huub Stapel when you need him most?

  • @smvstexel HUUB Stapel, until now, you´re not forgotten . And we will never forget ya my superhero ;) 

  • @smvstexel Such a nice little reference, so very little people that will understand it.

  • I this is really Horror, that poor little girl, she will have nightmares. Multiple error. Was this maybe an old elevator without e-breaks against uncontrolled moving upwards...? Same thing seemed to be happening in New York, but there a woman died by the car moving up. Please tell me this can not happen with newer elevators....

  • @luxembourger this can´t happen with modern elevators... they all have a seperate "driving and falling control unit" that works also without power due physics trigger system....

  • Lol I thought it was going to hit the ground at a high rate of speed not shoot up to the top and blow the ceiling out. That kid was damn lucky. WOW

  • wtf happened there?!

  • Safetys/governors needed on the counterweight perhaps!?

  • Welcome to the baltimores James Brown motel

    

  • Bitch please, I won't do anything if you thumbs me up.....

  • OMG WATH HAPPENED???????

  • Seems like the brake is broken so that the motor reduces the speed in every programmed floor. But after the motor turned off, the elevator speeds up again. The counterweight seems to crash down in the shaft mine... Am I right? Modern dual circuit brakes should work in two ways by the way.

  • @DR00G13 On a geared machine (like this one) the brake is fitted alongside the motor. Next is the gearbox, then there is the sheave which drives the cables. The brake is released only while the motor is running.

    It would seem that the gearbox is mechanically failing,until 1:28 the gearbox finally "completely" fails and the lift is in freefall - the sheave now has no connection to the motor, gearbox or brake. It is in freefall UPWARDS because the counterweight is 50% heavier than the lift car

  • @mrmattandmrchay: I see. That's another good explanation... I wish there would be sound in the vid. I think it would say more than a thousand words ;o)

  • @mrmattandmrchay Looks like brake failure. I've had that myself on a goods lift at work. The first part of the video the speed is normal as long as the lift is driven by the motor. Once it stops the brake should take the load instead of the magnetic motor field. The brake fails, lift moves and the controller compensates by activating the motor, keeping the speed low. Once the governor switched off the power all that was left was the failing brake. Hence the lift overspeeding at the end.

  • @mrmattandmrchay (continued) In this case it looks like the overspeeding was actually caused by the governor. Had it not switched off the power, the motor would have kept the speed much lower.

    This could only have happened if the trip speed of the governor was reached before the controller activated the motor to compensate the incorrect position it detected. Once activated the motor would have kept te speed at its normal value and the crash would have happened at a much lower speed.

  • At :30 they jump they didn't fall they jump to the lobby or what ever it's called

  • I would love to see the part when building management look into the lift to see the aftermath!

  • This is what happened to that poor woman in New York. It was a good thing that was a little girl, because she was short enough to make it out without being struck by the top of the doorway.

  • It's kind of funny

  • @saltboss1 I love elevators I just hate elevators for that reason

  • And THAT is what final limit switches are for.

  • @PivotMasterD1 Which in this case, are completely useless.

  • ~I din't get it....

  • No this is "Human error" Brake spring adjustment

  • daammnn it picked up a lot of speed right before hitting the top, they're lucky they got off!!!

  • This is why I am honored to always take the steps.

  • LOL

    OMG

    WTF HAPPENED?????

    :O

  • OMG !!!! What happened??!!! :O

  • thyssenkrupp elevator in são paulo,brazil

  • Comment removed

  • I am a elevator tech, this elevator pulled thru the brake(in up direction only) the counterweight weighs much more than the elevator. I dont believe it has been maintained and inspected by qualified a elevator Tech. 

  • @dewhitt98 Is it possible that the primary motor relay fused due to excessive amphere's condition? (assuming this elevator has an ancient relay controller attached)

  • hä?

  • This may be due to brake failure. Counterweight pulls up the elevator cabin.

  • why do the doors open and close so often???

    and what happenend in this video?

    and are the two guys dead or alive?

    crazy video!!!

  • @100DarkDude 1 is a girl. They are clearly alive, and it malfunctioned

  • Creepy

  • hydraulic is a bit better

  • this guy just screwed with controls of elevator and make it hit the top and taped it as if it is a real crush. it has to hit the bottom to be a crash. once i ve heard an elevator just fallin down one floor, i couldnt hear anything two hours.

  • well happy wany to it

  • Got out just in time..damn

  • if this happens to me one day I wont get ever again on an elevator

  • woah

    

  • that why i use stairs

  • Dad*

  • I'm glad the girl and dag got out safely lol

  • And THAT is why I hate elevators!!!

  • @connorboxer123 me too, im am deathly affriad of riding in an elevator.. i only do it when im forced to do it with my three kids in the wagon or stroller and i have to have someone ride with me mainly in fear of getting stuck and these videos on here dont make my fear any better lol

  • @connorboxer123 I agree

  • @connorboxer123 i love elevaters

  • @connorboxer123 new ones have extra safety. they just brake and stop moving in something like this. the fear is the wire snapping and your going terminal velocity into the ground below.

  • @iToasterman If the cables were to brake, this is what the car brakes were designed for. The governor would lock and pull the brakes into action. The car brakes were not designed for a runaway lift going up. Yes, the governor would still shut the lift down, but the lift motor brake is fitted BEFORE the gearbox. If the gearbox were to mechanically fail, the counterweight being 50% heavier than the lift car, the car would naturally go up. Gearbox failure? Almost unheard of and extremely rare

  • @mrmattandmrchay See... watch?v=RAyqPEdBXV0 at 06:40 where you can see the parts that I am talking about (Motor>Brake>Gearbox>Sheave)

  • @connorboxer123 I dont know why I am watching this stuff, but there are elevators I swear I NEVER want to go in.

  • This could have been a deadly situation. Passengers were fortunate to avoid a potential horrible scene.

  • VERY DANGEROUS ELEVATOR AND GUILLOTINE! DAMN IT NOW!

  • LOL the phone fell off the hook

  • Comment removed

  • its the tower of terror ride that never stop

  • @dellcomputer445 My thoughts exactly.

  • auftgavkeugykhjgcaksjchdakdjhr­ygejrhbvgjbhsdjfvhgawfvjchgfvu­ydfgvhgvcasjdhgcskdfhvgsfdcgvd­chgv shgdcfbvjshgdcvsdchgvsndvghsdg­vasjdvbcjfbrhedfrgerjhvbdjbhvf­sjefbvhhdcbghdbhtyuj

  • Fortunately on some modern elevators the mechanical speed controller (and the car brakes) works in both directions.

    However the car got fast after 1:30, probably due to a mechanical failure.

    What happened before that time was caused by a failure on electric safety circuits (the car started moving before closing the door).

    All I can say is that I wonder how an electric and a mechanical failure happened at the same time.

  • That little girl was almost pinched in two!

  • lol wtf? very unsafe elevator. in normality must the elevator stop, when the door is open. there is a safety circuit that stops the elevator.

  • non c'è il freno di emergenza che agisce sulle guide della cabina? Oppure si inserisce solo per un eccesso di velocità?

  • @figamarsa

    Il freno di emergenza sulle guide di cabina (paracadute) agisce per eccesso di velocità o allentamento funi, ma negli impianti a vecchia normativa (costruiti prima del 99) lavora solo in discesa.

  • Provided what mrmattandmrchay described below didn't happen (it probably did though), If this were an older relay-driven elevator, either the Up relay is stuck, or the DO/DC relays are shorting, or both.

    mrmattandmrchay's description is more likely what has happened though

  • @syg068 (2) are rammed into position by the car travelling downwards, therefore they are useless with car going up.

    If you look this vid, at 1:28 the doors stop opening/closing which suggests the governor overspeed activated, removing the power and applying the brake to the motor. If the motor is no longer physically attached to sheave, well, "maybe" you could get what happened here.

    A gearless machine...

    The sheave, motor and brake are ALL ONE UNIT, so this probably couldn't happen.

  • @syg068 (1)A geared machine...

    motor>brake>gearbox>sheave- the sheave is a wheel that moves cables up/down.

    The brake stops the motor moving, so if the gearbox was missing, the sheave would be loose and the lift car would move depending which was heavier-the car or the CW.

    This relies on the mechanical connection between gearbox and sheave. How can this ever fail? It can't in theory, but 'nothing is impossible'.

    If you see..."Watch?v=DkWkgoeLZzU" at 0:40 the car brakes are (continued2...)

  • wouldant like to be the little girl in that

  • I'm shocked!! Interesting the way the lift car got faster and faster...

    I can only think that the worm-gear (gearbox) had been damaged and detached from the motor, leaving the sheave in freeflow without a brake. From there the counterweight being heavier than the lift, took the car straight up. In this situation, the governor would be useless to stop the liftcar, as this could only apply the brakes with the car travelling in the downward direction.

    Interesting....

  • @mrmattandmrchay Never seen anything like that before, its dangerous too. As there was no 1 in there, cool smash up.

  • @mrmattandmrchay Sounds it! I am not an elevator tech by any means but I was told by one it IS possible for an elevator to " Fall upwards".. Hence why all elevators in Canada or at least the Provence of Ontario have big " cable grippers", spring applied, released and held hydraulically, but when power is removed from them via tripping the govenor, loss of supply or whatever, BAM they grab and the car 'aint goin' nowhere.

  • @mrmattandmrchay Why would a governor device not work in an upwards direction?

    If there's no safety fallback in the case of elevator falling "up" (and we are just relying on the brake operating normally) then this seems really dangerous!

  • @mrmattandmrchay Actually, I just read your other comment re governor working downwards. Surely all that needs to be done is a governor cable attached to the bottom of the car so safeties could be applied on upward travel, if needed!

  • @cakebandit0o If you see... watch?v=DkWkgoeLZzU 0:21 until 0:50 this explains a governor operation very well, and you will see that the brakes on the lift car are only pulled into action by the car moving "downwards"

  • Wow that thing is screwed!
