In ancient China and European countries, people and goods were transported vertically by windlass and other tools. Modern elevators are the product of the invention of steam engines in the 19th century. In 1845, the first hydraulic elevator was born, and the liquid used at that time was water. In 1853, elisha otis, an American, invented the automatic safety device, which greatly improved the safety of the cable traction elevator. On March 23rd, 1857, the first passenger elevator using Otis safety device was installed in a five-story shop in new york, USA. Since then, the use of elevators has been widely accepted and developed at a high speed. The original elevator was driven by a steam engine, so the building must be equipped with a boiler room. In 188, Siemens, a German, invented an elevator using electricity, and a veritable "elevator" officially appeared.
Shanghai is the first city in China to install elevators. In 197, two Otis lifts were installed in the six-story Huizhong Hotel. Taiwan Province's first commercial elevator was installed in 1932 during the Japanese occupation, and it was located in the "Juyuan Department Store" in Taipei, then known as liu Cage (Minnan: Li? -l? ng）。
escalators
Two Americans studied escalators at the end of the 19th century. In 1897, jesse w. reno built an escalator-like mobile game in the amusement park of Coney Island, new york, USA. In 1898, charles seeberger bought a patent for the invention of escalator, and cooperated with Otis Elevator Company to manufacture the first escalator with horizontal steps, handrails and comb plates in New York State in 1899. At the Paris Expo held in 19, Seeburg successfully exhibited their products under the name of "escalator" and won a first prize. In 191, Otis bought the patent of Xiberg, and then bought Renault's company the following year. In 192, Otis combined the two designs and became the basic design of escalators today.
Shanghai was the first city in China to install escalators. In 1935, Daxin Department Store in Shanghai installed two Otis single escalators, connecting the ground to the second floor and the second floor to the third floor.
