It is reported that the 2000 China lifts (escalators and vertical lift is included here) of only 37,500 units sold, that is since then elevators began, China has gradually transited from subsistence to self-sufficiency and export the synchronization period of rapid growth. 8 years 2000-2007 composite high-speed elevator production and sales volume growth in China in recent 30%. And began Yu 07 of global financial crisis hit has elevator industry high-speed growth of waist, due to elevator industry has lag, in 08 passengers elevator industry sales volume growth Xia down 13%, to 09 financial crisis of lag effects more is, China elevator industry association January 10 latest forecast 09 export substantially declined 30% around, even domestic elevator market growth 13% around, 09 overall elevator sales volume growth still Xia down 5% around. 08 as 245,000 units, by this calculation 09 elevator production and sales volume of about 257,000 units.

Villa lift the next 35 years will dramatically increase

It is reported that this specifically for the Villa country home elevator to fill the gap in the market for such products on the past 3-5 years in North Canton in first-tier cities from trial sales to become. Technetronic electrical and mechanical analysis of Shanghai officials said this elevator solves the mobility problem of elderly people, people with disabilities and down the stairs, for a single commercial elevator industry is undoubtedly opened up a new market segment. Currently a city Villa sales in Guangdong has entered a period of steady, Southwest region also has wide Villa elevator market.

Also affect the rise and fall of Terminal industry, as base parts of the elevator industry, the future situation will be favorably, lift Terminal is the terminal a branch of industry is particularly important, with pluggable terminal blocks, solder terminal field. As shown in the following figure, in the elevator control unit, Terminal can be seen everywhere.

Failure cause

(1) automatic switch
Because all closed Hall and car door is a prime condition of Elevator, elevator door interlock system if a failure occurs will not run. This kind of failure is determined by various electrical components, including automatic door lock caused by bad contacts or not adjusted properly.

(2) electrical components
After electrical and electronic components are insulated in the long run always be caused by aging, failure, moisture or other insulation breakdown, causing elevator failures caused by electrical system for open circuit or short circuit.

(3) contacts of circuit breakers
Made out of relays, contactor control circuits, the failure occurs in the relay contacts, contacts by high current arc ablation or, contact adhesive will cause a short circuit. If the Reed contacts are blocked by the dust or contact loses its elasticity will cause circuit breakers, contacts of open circuit or short circuit will cause the elevator control circuit failure cause the elevator to malfunction.
