Elevator culture from steam to electric

On March 23, 1857, the world's first passenger elevator appeared in the 5-story Howholt Building in New York. This elevator was installed by Elisha Otis. In 1853, at the New York World's Fair, Mr. Otis cut the cable of the elevator filled with goods in public to show the safety lifting device he invented, and the "safety ladder" was born. At that time, the safety ladder was not so much a means of transportation as a cunning device. The owner of the Howholt Building thought the new safety ladder would attract more people and lead to more buyers. The elevator in the Howholt Building is powered by a steam engine installed in the basement, so it cannot yet be called an "elevator", and the speed is only 12 meters per minute (for ease of understanding, hereinafter referred to as "elevator").

The original elevators were expensive, known as "ascent rooms" or "upstairs buses," and were found mainly in hotels in New York, London, and Paris. The first passengers in the elevator want to experience the amazing new technology and the ostentatious sense of luxury spending. The "rising rooms" of this period were generally beautifully designed, with upholstered seats, walls studded with mirrors and, in some cases, a chandelier.

Soon, speed became the most important driving force for elevator development. In the 1870s, elevators underwent a transformation from hotel toys to office building necessities. When the life Insurance building in midtown Manhattan was completed in 1870, the eight-story, 40-meter high office building was equipped with elevators at the design stage, which was a pioneer. The elevator in the life insurance building was also made by Otis, and the steam units had been replaced by hydraulic systems that were faster and easier to maintain. The industry standard of "elevator response time no more than 30 seconds" was established in that era and has been used to this day.

Soon, office buildings and apartment buildings in New York began to install elevators, and with the advent of steel frames, urban buildings continued to soar to new heights. In 1885, the world's first skyscraper, the Home Insurance Building, was completed in Chicago, with four elevators serving 10 floors, and the elevator shaft was the design core of the building.

A look at history shows that before elevators were popular, low floors were most popular because people didn't need to climb stairs. The higher the floor, the lower the rent. With the advent of elevators, the higher floors became the more valuable floors of the building because they were away from the stench and noise of the street. In the late 19th century, with the rapid development of science and technology, the hydraulic system of the elevator was transformed into an electric engine. The modern electric traction elevator was developed in the first two decades of the 20th century and is still used today.

In the 1920s, avant-garde architects were elevating the skylines of bustling cities, turning once-unpopular,

Almost untenable space turned into stylish apartment with terrace. High-rise apartments are the new fashion. The Empire State Building, which opened in 1931, was the new symbol of fashion during this period. The 103-story skyscraper remained the tallest building in the world until 1970, with 73 elevators, each traveling at 365 meters per minute, becoming an integral part of the legend of the Empire State Building. Currently, the world's fastest elevator is in the Shanghai Tower, which is currently the tallest building in China and the third tallest building in the world with 106 elevators.
