gBisegliTop floor height: The net size between the completed ground level of the top floor decoration and the lower skin of the shaft roof.
Development direction: . Elevator group control systems will become more intelligent. . Ultra high speed elevators are getting faster. . Bluetooth technology is widely used in elevators. . Green elevators will be popularized. . Visual systems or human-machine dialogue industry data shows that in the first half of ， the growth rate of Chinas entire elevator production exceeded %. In the second half of ， the proportion of shipments to orders decreased， but the annual growth rate of production and sales remained around %， which slowed down compared to the previous year. However， it is a foregone conclusion that the total production of elevators throughout the year will exceed units， and the national elevator ownership will reach over . million units.
QAdiakThe huge market space has made the industry one of the earliest industries for foreign investment to enter. Major global elevator well-known enterprises have established sole proprietorships or joint ventures in China. The entry of these foreign brands has brought international technical standards， management concepts， and business models to the industry，Hydraulic turnover machine enabling domestic elevators to quickly enter the international ranks. From the perspective of industrial layout， the agglomeration effect of the domestic elevator industry is obvious. The manufacturing of elevator complete machines and components is mainly concentrated in the Yangtze River Delta and Pearl River Delta regions. Apart from high-end elevator components， elevator components have basically achieved localization.
AxSlide elevators are installed inside buildings and are often associated with buildings，Sidewalks are used in parallel
Why do elevators suddenly rise and fall?
On December -， ， the first batch of national elevator production and installation license review meetings were held in Guangzhou. After this review， a total of elevator production licenses of elevator production enterprises have passed the review， a total of elevator installation licenses of elevator units have passed the review， and a total of elevator installation licenses of construction and installation enterprises have passed the review.
pThe permanent magnet synchronous toothless traction machine will replace the traction machine composed of a worm gear and worm drive pair asynchronous motor. Nowadays， passenger elevators and sightseeing elevators all use permanent magnet synchronization while freight elevators are mostly used for worm gear and worm traction machines.
YIn ，Hydraulic turnover machine the Industrial Electromechanical Unit of the Construction Department of the Shanghai Municipal Public Works Bureau began to be responsible for the registration， review，LechePrice of hydraulic flipperMain development trends of and licensing of elevators throughout the city. In ， the system of elevator maintenance engineers was proposed and implemented. In February ， regulations were formulated to strengthen the regular inspection of elevators， reflecting the early emphasis on elevator safety management in China.
VwhereAfter the elevator reaches your destination floor， it will automatically open the door， and exiting the elevator in sequence will end the elevator ride.Relevant laws， regulations and technical specifications: The Special Equipment Safety Law was issued by the Standing Committee of the National Peoples Congress on June ， .
rOGroup controlled elevators are elevators that use microcomputers and centrally dispatch multiple elevators in parallel. Group control includes elevator group programs，Home elevator, villa home elevator, small home elevator, home elevator brand - home elevator manufacturer elevator group intelligence， and other forms of classification based on the location of the machine room. There are elevators with the machine room at the top of the shaft (upper machine room)， elevators with the machine room at the bottom of the shaft (lower machine room)， and elevators with the machine room inside the shaft (inorganic room).
In ， Swiss Schindler established an agency at Jardine Engineering Corp. in Shanghai to carry out elevator sales， installation， and maintenance business in China.
Mr. Otis invention has completely rewritten the history of human use of lifting tools. From then on， taking elevators is no longer&quo; The Game of the Brave&# quo; Elevators are widely used worldwide. In ， Otis Elevator in the United States manufactured a veritable elevator， which uses a DC motor as power and uses a worm gear reducer to drive the ropes wrapped around the drum， hanging and lifting the car.

OLight curtain protection is a door protection system that uses infrared beams to cover the entrance and exit of elevator doors， detecting people or objects. This ensures that the elevator will not pinch people under any circumstances， and elevators are also advancing. Over the past years technology is developing， the materials of elevators have changed from black and white to color， and the styles have changed from straight to diagonal. In terms of operation， there have been even more innovations& Flash; Handle switch operation， signals， collective selection， human-machine dialogue， intelligent group control; The double decker elevator demonstrates the advantages of saving shaft space and improving transportation capacity; The emergence of variable speed escalators has greatly saved pedestrians time; Different Shapes&ndash& Flash; Fan shaped， triangular， semi diamond shaped， semi circularThe circular sightseeing elevator no longer blocks the view of passengers inside. FM door control， intelligent remote monitoring， energy-saving host， low noise and durable cabinet， new elevators that have collected new scientific research achievements in the fields of machinery， optics and so on have been launched. As a result， cold buildings shed light on human nature， and peoples lives have become more beautiful.
kBisegliHigh speed elevators often refer to elevators with speeds greater than -m/s.
