Dry elevator maintenance for 7 years, maintenance of more than 600 elevators, straight want to sum up this problem。

To pave the way, 65% of the elevator quality is determined by the manufacturing process, 25% is related to maintenance,

10% is related to the hygiene of the car, 10% is natural wear and tear, (estimate error 3 points)。

Work encountered an elevator 2 years have not reported repair times, he called Sanling Lingyun "production"。

In the other area, 10 elevators will also change the lights and replace the fans, basically not bad, the brand is Yong,

With Hitachi motherboard, it has been proved that the quality of the Japanese elevator is flowing。。。。。

Back to the building addressing, and the quality of domestic parts is very poor, the door machine holding the light curtain motherboard communication board buttons are very skilled。

Audi rs communication system is very outdated, now the mainstream is the German can communication, stable and good maintenance。

Domestic products are different in terms of software, are bought new Shida or Menak system, quality is mainly reflected

In terms of hardware, determined by the level of processing and manufacturing, the quality of raw materials, and the quality of outsourced parts, in general, there is no home that does not cut corners, and has not seen the parts or materials used by the factory, which are 50 steps and 100 steps!

Compared with the hardware of the joint venture, the distance of 50 years is that the parts processed by the same set of drawings have obvious differences in accuracy, thickness and smoothness!A door gasket, Mitsubishi is galvanized steel sheet surface, the domestic soft iron sheet has not been handed over to rust, this TM can save how much money？

The same design life is 15 years, the car can be a 3-year warranty, but the elevator is provided with a warranty year。

Hunan ElevatorOr chooseHunan Alpha elevator Engineering Co., LTDLimited company providedGerman elevator brand Alfa elevator。Still good。
