Aim at the energy-saving elevator that decrease a platoon to exhibit shop sign of ” of green of dozens of big “
The reporter discovers in look around, each ginseng exhibits business to hold high banner of ” of energy-saving, environmental protection rolls out “ large quantities of innovation product, a the largest window in becoming elevator to exhibit. Super- the elevator of high speed high capacity, passenger lift that contains system of second birth of the sources of energy, can identify type of the safe system of unusual action inside car, crossover automatically automatic staircase be in in succession exhibit appear on the meeting, promote a taller state the product technology of world elevator.
As we have learned, at present domestic elevator retains the quantity has exceeded many 80, but energy-saving elevator still is not occupied 5% . Accordingly, elevator company is rolled out more energy-saving, more the product of environmental protection is very pressing.
3 water chestnut: 20 years of casting with respect to sword of “ green ”
3 water chestnut become the design that exhibit a stage meticulously the appearance of greenery. Foil in greenery the 3 water chestnut below continue to fulfilling an industry with the catchword of the world ” of the 3 water chestnut of “ green, green pioneer person acceptance, more energy-saving, more environmental protection, faster elevator is pushed to global user.
Technical innovation is the cornerstone that elevator of 3 water chestnut extends the market all the time. 1982 electric machinery of 3 water chestnut is transformation of frequency conversion of communication of the first one or two (VVVF) control technology applies to elevator, brought the technical innovation with elevator epoch-making bound. 1997 electric machinery of 3 water chestnut permanent magnetism of the first one or two is synchronous (PM) bring a technology to be used to elevator without gear drag, decided with this 3 water chestnut are in the lead position of elevator scope technology. Electric machinery of 3 water chestnut was developed again 2004 but gearshift elevator technology, led elevator product thereby to domain of energy-saving, environmental protection extend.
