The Historical Development Of Escalator

    The movable staircase was patented in 1892, but it wasn't until 1899 that it had its own name--"automatic staircase". Each step is carried by 4 wheels, and the 4 wheels rotate in a track that hides underneath. The track is horizontal at the top and bottom of the escalator, allowing people to step on or off the stairs. The steps form a continuous turning loop, just as the stair ring on the escalator today. The automatic sidewalk "changes on the basis of an automatic staircase and has an active horizontally walkway. It is mainly used in airports, because people often carry heavy baggage in airports for a long walk. Now big and small market and supermarkets have automatic staircases exist, we will never be unfamiliar. But there are always people who don't know his name. Even call it an elevator.Escalator
    Mankind has a long history of transporting goods and personnel using lifting tools. As early as the 2600 BC, Egyptians used the most primitive lifting system when they built the pyramids, and the fundamentals of the system remained unchanged: the load-platform rose as a balance fell. Early lifting tools are basically human-powered. In 1203, a donkey-powered crane was installed in a monastery on the coast of France, which ended the history of carrying heavy weights. After the British scientist Watt invented the steam engine, the crane device began to use steam as a driving force. Immediately thereafter, William Thomson developed a hydraulically driven lift ladder, and the hydraulic medium is water. On the basis of these elevators, generation after generation of innovative engineers are constantly improving the technology of lifts. However, a key security issue has not been resolved, that is, once the lift cable has broken down, the load platform will certainly crash.Escalator
    With the rapid development of economy and the deepening of urbanization process, China's elevator industry is experiencing a high-speed development period. China's elevator production increased from 10,300 in 1990 to 365,000 in 2010, annual composite growth rate of 19.5%, the domestic demand for elevators from 2000 only 37,200 to 329,700 in 2010, to the end of 2010, our country has more than 1.6 million elevators, as detailed in the "China Elevator industry market Demand forecast and Investment opportunity Analysis report."Escalator
