Evolution and status of elevator technology today, a large number of technology development and application of high-power semiconductor element microcomputer makes elevator control systems are increasingly automated, intelligent, forward exchange FM regulator technology power, high speed direction. At present, the development of this technology has enabled the exchange speed drag lift speeds of up to 7m / s, will gradually replace the DC drag lift. Second, the status of the elevator lift production technology, its history of the development of a short elevator, before the founding of New China, only Shanghai, Tianjin, Beijing Otis Elevator Company of the United States service stations, but only repair Elevator parts, elevator can not manufacture. After the founding of New China, the period from 1952 to 1954, high-tech zones escalators, China has in Shanghai, Tianjin, Shenyang has established three elevator manufacturer. By the 1960s, again in Xi'an, Guangzhou, Beijing and other places have established elevator factory. To 1972, there were eight elevator sentinel manufacturers, with an annual output of nearly 2,000 elevators. Since 1978, the escalator parameters in the economic growth and the expansion of the scale of the project, the escalator brush, lift completely dominate the market in 1985 by a seller and occupation, the situation has greatly stimulated the lift production. Elevator decoration design residential elevators residential elevators on decorating more consideration to be adapted to different ages and cultural qualities of the crowd. Children playing in the car or the car may collide with the armrest wall; old people look bad may encounter difficulty operating layer selection; low quality of the people likely to smoke inside the car caused by fire; a drunken man may car car, landing door and manipulate disk damage. Also likely to be hit residential elevators furniture and bicycles of some items. So when housing ladder are decorated palanquin wall decoration to consider using some of the energy buffer material, but not the use of wood and other flammable materials for decoration. In the car dashboard buttons and floor indicators are to be the appropriate size, and choose a more eye-catching colors, taking into account their higher anti-destructive and are destroyed after security.
