Elevator Controlled by Evil Spirits?!

Elevator Goes Up 31 Floors In 15 Seconds (VIDEO)

Take the stairs!

José Vergara Acevedo was launched 31 floors in 15 seconds when an elevator malfunctioned in Providencia, Chile on Saturday, according to MyFox8.

Video of the incident shows the Acevedo desperately trying to push buttons to make the elevator stop.

The man suffered head and leg injuries when the elevator eventually crashed into the roof, according to Emol Chile.

Modern elevators in the U.S. are typically equipped with brakes that are activated if an elevator starts moving too fast or too slow. It's unclear if the elevator in question had those brakes, and they malfunctioned, or if none existed.

The elevator was in a building that had been completed eight weeks ago, the Independent reports.

It reached 50 miles per hour in its frightful climb.

It's a miracle that he survived it!

Hardly evil spirits. Probably more likely is lack of common sense by those who installed it. Ah, why do we need to put this wire to this post? It's good enough. Duct tape it.

The odd thing about this incident is that that elevator was launched UP like that instead of the usual catastrophic scenario that we see in horror movies where an elevator, filled with people, inexplicably does a rapid free-fall from a top floor all the way down to the lowest level of the building.

But this elevator in this incident was inexplicably launched up, like rocket, where it crashed through the roof of the building (or nearly so).... which to me is a real first as far as I'm concerned because I've never heard of an elevator doing that before.

I would say that would have more to do with gravity and less to do with evil spirits. There's no such thing as something that remains inexplicable. I'm sure if we dig hard enough we'll find the reason. I'm putting my money on mechanical failure, but if you'd rather put yours on Madame Blavatsky, be my guest; after which, I have a bridge I'd like to try and sell you. ;)

I'm sure it must be close to the record for the worlds fastest elevator. I wonder what kind of motor was running it to get to that speed. Clearly the first thing you need to look for is a logical explanation. The report doesn't say there hasn't been any engineering reports to say a mechanical fault wasn't the cause. Its a bit of a jump to say evil spirits are to blame and as Mileman points out its probably mechanical.

I think it's modulated to be slow (in high rise buildings!) but there is potential for catastrophic failure due to electrical brakes.
Power failure causes brake to engage?
Well what about a power surge or a short, etc.?
This sort of thing is why I hate fly-by-wire, and it carries over logically to elevate-by-wire lol :)


Gearless traction machines are low-speed (low-RPM), high-torque electric motors powered either by AC or DC. In this case, the drive sheave is directly attached to the end of the motor. Gearless traction elevators can reach speeds of up to 2,000 feet per minute (10 m/s), or even higher. A brake is mounted between the motor and drive sheave (or gearbox) to hold the elevator stationary at a floor. This brake is usually an external drum type and is actuated by spring force and held open electrically; a power failure will cause the brake to engage and prevent the elevator from falling (see inherent safety and safety engineering).

"inherent safety" makes me laugh and shiver at the same time.

p.s. not to suggest haxx0rs but it's possible to hack an elevator... eek

p.p.s. a faulty Governor (lol!) can likely lead to a hurtling elevator. :(


The governor, which is located in the machine room or overhead depending on the elevator design, is a speed monitoring device on traction elevators that triggers the safety mounted on the car frame when the elevator over-speeds in either direction. The governor rope runs over the governor sheave and down to the elevator car and is attached to the safety trip mechanism. The governor rope continues to the pit and runs over a pit mounted sheave and turns back to the governor sheave located in the machine room or overhead. This governor rope arrangement forms a continuous loop while the elevator moves up and down the hoistway.

p.s. if we'd been able to Google what was wrong with the C130s the job would have been faster. freaking 1970s tech manuals smelled funny lol

Light load and elevator danger: travel with a fattie


An elevator can also over-speed in the up direction. With a 40% counterweight and an empty or lightly loaded elevator the elevator car would be pulled in the up direction while the counterweight, in this situation, would be the heaver mass and move in the down direction. The governor would sense the over speed condition and set the safety which would stop the upward traveling elevator.



:becky: the irony is that most people would choose a less crowded elevator when in fact a heavily loaded modern one may well be safer. if you don't wanna be a human wafer, hehe :heh:

[Roisin]

It has to do with the counterweight that's supposed match up to the weight of the elevator itself. In this case, the counterweight weighed much more hence why that elevator shot up like a rocket. But that alone was not the culprit because based on what I've been reading on this, those who are in the elevator business are saying that there were a number of factors that would have had to contribute towards an event such as this and for this reason, that it happened at all is quite extraordinary.

Also, only joking about the "evil spirits' thing and was only a reference to a recent horror movie ... can't recall the name at this moment but was something about devil being in an elevator.... lol. Huffington Post entitled an article about this elevator incident as "The elevator from hell" in reference to that movie.

under certain conditions it's possible to see a "cascade" of faults -- otherwise known as a catastrophe :(

in other situations, it could be because a human being screwed it up i.e. meddled with safety mechanisms hoping to hurt more people --
but the single-person ride seemed to set it off.. unlucky fellow there, Murphy's law, haha :(

Well it depends, it may be a new building but negative energy always sticks around no matter what changes in a environment so you can't rule it completely out, ancient berial grounds get disturbed by building on their location and this is usually the result but I've seen much worse than this though.
