Things You Don't Know About Modern Elevators

In the beginning of today, we posted a message about a man trapped in the elevator for 41 hours in an article in New Yorker. However, the real jewel of this article is the mountain "Do you know ...?" Like the button to close the door, are you always pushing? Yes, I can not. This is a complete list:

As mentioned above, the door closing button is the illusion that it mainly provides control to passengers. The elevator was built from the early 1990s. This button works only in emergency situations and is maintained by the authorities.

The only phenomenon in 1945 when the elevator car dropped freely due to a cable power outage (fire or structural collapse). The B25 bomber hit the Empire State Building and blocked the cables of the two elevators. There is a woman on the 75th floor of the elevator car, but thanks to the lower 1000 ft cable she survived. And that reduced the impact.

The elevator is 20 times safer than the escalator. The elevator is 20 times the escalator, but the accident increases by one-third

Elevators are safer than cars. In the United States, on average, 26 people die each year by an elevator. 26 deaths every 5 hours

The Otis Elevator Company carries an elevator which is equivalent to the world's population by elevator every five days.

The New York Marriott Hotel is the first company to introduce a smart elevator system that assigns passengers to elevators according to the story to be visited.

Elevators previously required the operation of two dispatcher / operator teams. The appearance of the navigation button obsoletes these tasks

For safety reasons, the elevator hatch is usually fixed with bolts. In the crisis of the elevator, the safest place is in the elevator

The myth about jumping off the elevator before it falls is it - myth. You can not jump quickly to offset the falling speed. I do not know when to jump

Depending on the laws of physics, the elevator can not exceed 1,700 feet. After that, the hoisting rope became too thick, and it was taken at 3,200 feet.

As an interesting conclusion, a man trapped in the elevator, Nicolas White, got a 6-digit low settlement after filing a $ 25 million lawsuit against the building. But in the process he lost work, money, and apartment. He is out of work now. [New Yorker]

Julie Douglas: Well, in order to seriously talk about mathematical problems, we need to talk more about how the modern elevator system works. Therefore, the first thing you need to know is that as you enter the elevator, sensors are automatically attached to the floor and the weight in the car is managed, so if the threshold is not sat on an overcrowded elevator I hear it. Because the sensor is saying that there are some people who get off.

I pushed up the button of the elevator and looked at the space before I knew the elevator door would open and close slowly. I jumped directly onto the elevator and tripped, the woman was there. She was wearing a septa, two leather chest pierces, and a dress that red hair dyed. But ... a few seconds later I talked to her and I felt that some of her was the same as mine. Just as we have a shared spiritual space. There will be big overlaps just as our psychological problems, needs, desires have Venn diagrams. I do not know how I got together from the moment I was at the same elevator, but I did it.

Some people think that elevators are simple ropes or chain cranes at the beginning (see the traction elevator below). The elevator is basically a platform that is lifted and pushed up by mechanical means. Modern elevators include cabs (also referred to as "cages", "cages" or "cages") attached to platforms in hoistways or sometimes in enclosed spaces called "hoistways". In the past, the elevator drive mechanism was driven by steam and hydraulic hydraulic pistons or manually. In a "towed" elevator, the car is pulled by a rolling wire rope over a pulley with a deep groove, commonly referred to as an industrial pulley. The weight of the car is balanced by the counterweight. Sometimes two elevators are built so that their baskets are always moving in opposite directions and weighted with each other.
