In principle of no floor.Lifts have safety mechanisms that block the lift if the descent speed becomes too high. These are separate from the ordinary electrical system. They are a kind of claws that hatch and fasten the cage and are activated by the inertia laws or by a leaf spring held by the strained cables instead. When the cable is patched, the spring jumps out and the lift cage is fixed.
If the worst case does not work, then everything depends on your own condition, the construction of the cage, any crumple zones, the buffers at the bottom of the lift shaft, etc.
Something that is equally well-connected, depending on the lift duct, is the compressed air that arises at the bottom of the lift because the air evacuates less quickly along the lift than it is compressed.It can also absorb the shock.
See for this: free fall along 75 floors
Since the 1930s, all lifts have a mechanical fall protection in the form of a brake on the conductors in the lift cage.Otis lifts was the first to come here. Nevertheless, the lift can still fall a bit before the automatic brake enters into force. Half a floor or so.. But there is another problem, halfway through the floor you can be hard to come out. Suppose you get stuck between the 21st and the 22nd, and you have to look through the flight hatch at the top of the lift cage. Still need steel nerves.
Think when you’re in a falling elevator, from the 10th floor, that it is possible that you are dead.
Although there have been greater heights, in which people survive, but that remains a mystery of course!Or it was not yet the victim’s time to go
Lifts are protected from falling in the shaft.At high speeds down, the lift slows down so that it cannot deposit.
You can be shaken together, and if you are not careful, you will get injured.But you do not collapse to the bottom of the shaft.
Should that happen then you open the door and jump on the first floor, just before you collapse quickly out of the lift.
4 High is already sufficient
23 floors, but I intend to be optimistic, so in the first place, how do you know for sure that the lift will ever crash?It can be stuck halfway or the lift shaft can be infinite, in which case the lift will never reach the ground;
Secondly, some people survived false distances where one would expect survival to be impossible;
And finally, if I am a cat instead of a man, then I can survive a much later autumn.
But let’s assume the lift speeds up at 9.8 m/s ^ 2 (i.e. the acceleration due to gravity on earth) and I am an average person and so I will die when I hit 27 feet per second to beat.So if the lift falls for more than three seconds, I’m dead.
In The first second I Fall 2.5 floors.In the second 7.5 floors and in the third 12.5 floors. So about three seconds I fall 22.5 floors, so let’s say that if I fall 23 floors, I’m a chopped ball.
If you jump right before the moment of impact, you survive every fall with a lift芒 鈧?娄…
