Do you know how does an elevator work?

Answer 1

I used to run one, you pull the handle back and it goes up; push it forward it goes down.

Answer 2

In the 1800s, new iron and steel production processes revolutionized the world of construction. With sturdy metal beams as their building blocks, architects and engineers could erect monumental skyscrapers hundreds of feet in the air.

But these towers would have been basically unusable if it weren't for another technological innovation that came along around the same time. Modern elevators are the crucial element that makes it practical to live and work dozens of stories above ground. High-rise cities like New York absolutely depend on elevators. Even in smaller multi-story buildings, elevators are essential for making offices and apartments accessible to handicapped people.

In this article, we'll find out how these ubiquitous machines move you from floor to floor. We'll also look at the control systems that decide where the elevator goes and the safety systems that prevent catastrophes.

Answer 3

It is quite a marvel of engineering. 1. The cabin is hanging on an iron rope (in fact there are 4 of them for security - if one brakes elevator stops), 2. Iron rope is rolled in or out over the puley that is on the roof. 3. Puley is driven by electric motor and gears. 4. Electric motor is controlled by electronic circuitry (in very old times relays) that is controlled by buttons you press. Long elevators have sophisticated speed control so they slowly accelerate and decelerate to pass the given distance in smallest possible time. For security reasons if the elevator goes down faster than the prescribed speed it automatically mechanically brakes. Some shorter elevators have cabins installed on the hydriaulik rode, instead of hanging them on a steal rope. That's about as short as it can be.
