Passenger lifts are suitable for buildings with high levels of traffic, such as residential, nursing homes, office buildings, shopping centers, hotels and so on. They are designed to provide high quality performance under high strength. So the history of the elevator you know?
Modern elevators have been in people's lives for 150 years, but in fact the elevator has been around for centuries. The Egyptians may have used them, but the first real evidence was found in the Greek and Roman periods. Through the Greeks, the first principle of the elevator is already in place. Then, the Romans later developed these principles, and in their own construction projects using the original elevator, the use of human, animal or water to drive the elevator. Records show that the arena has a hydraulic lift, used to slaves, lions, etc. to the central stage.
The elevator in the seventeenth century is the pioneer of most of today's elevators. Later in the same century, the world's first production of passenger elevators at the Palace of Versailles was set for Louis XV. Elevator technology in the early 18th century to further improve, to 1830, passenger elevators in Europe, especially the factory is particularly common. However, safety is a problem because the elevator falls too easy on the shaft. So in 1852, the world's first passenger elevator safety brake was invented.
The elevator revolutionized the way we live, and let us be able to conceive our city. Our 21st century vertical life dream, tower, only because of the invention of the passenger lift and become a reality. The elevator is now the apartment, business and leisure facilities are needed, has become a permanent fixed device in our lives. The disabled passage is legal, and the elevator makes this possible.
With the skyscrapers getting closer and closer to the sky, the elevator needs to be run faster and faster, and the distance is getting higher. And as the population grows, people are increasingly in need of space. Only so many ground spaces are available, but passenger lift may expand upwards. Now we can build giant office buildings, large units and huge shopping malls. This means that we are in the city's development up rather than only horizontal development.
