Say it first湖南电梯Belongs to the special equipment, the common is the escalator and the straight ladder。The escalator can be lifted by the whole ladder, that is to say, if the height is very high, the two escalators can be put together。Therefore, the quality of the escalator mainly depends on the quality of the product, which is why the elevators in important places such as subway entrances and exits are basically Schindler, Kone, Thyssen Hitachi, and other imported brands。
The straight ladder must be assembled on site, and there are many uncontrollable factors on the site, so the comfort of the straight ladder directly depends on the quality of the installation。

Since installation has such a big impact on the later stage, I will talk about installation in detail。

As far as I know, most elevator companies are installed by third parties, which is the so-called elevator installation company。The elevator company only needs to send a person similar to the project manager or project supervisor to manage the macro aspects of delivery, collection, installation schedule and so on。These so-called project managers are not highly educated, similar to many contractors who do projects, making money is always a bit。During the installation process, a bad accessory, the elevator water, these people like to win the lottery like happy, so the quality of this line is really not flattering。

The actual installation of the elevator installation team, but also good and bad, some are with a family with a mouth, family men and women and children just lost the hoe to the elevator, do you think these people Ann elevator is guaranteed？

After the conclusion of the escalator is really the import ladder is better, the straight ladder to see the installation, if the installation quality is not passed, cut all in vain。
