The history of the escalator
The origin of the escalator should be traced back to 1857, when Nason Amis declared a "escalator" scheme, the scheme is driven by a roller through continuous movement, end to end, stair.
In 1897, Jess Reno (Jesse W. Reno) built a skew board walking game similar to escalator in the amusement park of Connie Island, New York. And Charles (Charles Seeberger). Seeburger in 1898 to purchase on the escalator patent to the next item, and cooperation with the Otis Elevator Co, 1899 produced the first level of the cascade in the state of New York, the escalator handrail and comb plate.
In 1900 at the Paris Expo, successfully displayed their "Seeburg escalator" (Escalator) in the name of the product, and won a first prize. 1910 acquired the patent case xiibaidian Otis, the repurchase of Reynolds company. In 1920, Otis combined the design of the two and became the basic design of the escalator today. The first step of the escalator to enter China was in 1935. Two Otis single escalators were installed in Shanghai's Daxin department store at that time, connecting the ground to the two floor, and the two to the third floor.
At the end of 1990s, the company has developed Fujitec transmission type automatic sidewalk, automatic sidewalk to segment speed, passengers entering from the low speed section, and then enter the high-speed running smoothly, then enter the low speed period of leave. This improves the safety of the passengers on the sidewalk up and down and shortens the time of the ladders in the long stroke. In April 2000, the United States Elevator World reports, Hamburg Thyssen escalator factory, manufacturing a full color escalator, comprising a glass fiber material, blue, green, red, grey and black. The color ladder provides the architect with a rich design imagination.
In from April 17 to 20, 2002, MITSUBISHI motor company exhibited the escalator model at the Fifth China International Elevator Exhibition. The more flexible drive rack structure can change the interval of the cascade at operation, so that the speed can also be changed. The speed of the inclined section is 1.5 times that of the horizontal section of the access water, which not only shortens the passenger's time for taking the stairs, but also improves the safety and stability of the passengers' escalators. In February 2003, Next Step released Otis escalator model, he uses the Guarded pedal, pedal and apron plate cascade into a single module coordinated operation; it also uses some other new technologies to improve the escalator safety, a new escalator.
At present, the major elevator companies mainly focus on the safety, energy saving and environmental protection of the escalators and the automatic sidewalks. But in the future, besides the above three aspects, the development direction of escalator and automatic sidewalk will also develop towards high speed.
