What does a good elevator do?

When we are riding an elevator, we usually feel the quality of this elevator with our own five senses. Only those elevators that are of good quality can bring good results to people. So what are the typical elevators that are good in quality?
First of all, high quality elevators usually do not go too much noise when they are in operation, so when people ride, they will not feel too much noise. If the noise is too big or the structure is not compact, or where it is, there is a problem.
Secondly, the high quality elevator generally takes a comfortable ride and basically has no sense of concussion. Especially when the elevator is climbing up, the feeling of shaking is not so obvious, and the feeling of passengers standing is also acceptable. But if it's part of the product with poor quality, whether it's up or down, it will cause a great degree of vibration, and there's essential difference between a good elevator and a good elevator.
Finally, the high quality elevator usually seldom fails, and there will be regular maintenance of professional personnel to ensure the safety of the elevator operation. Those commonly used elevators are generally older, and most of them are used without professional maintenance. Therefore, this type of elevator also has a large safety hazard.
