How much is the elevator maintenance fee for the thirtieth floor a year?

The elevator industry is called maintenance, and there are two calculation methods. One is light package, that is, simple work such as cleaning, oiling and dust removal is usually done. Be responsible for opening the door when the elevator is closed. The elevator is broken, and it is responsible for maintenance, but the spare parts fee is paid by the property, 3000-4000. This refers to the general brand, and the first-line brand will be more expensive. One is the big bag, as the name implies, that is, they are responsible for all the expenses. This kind is more expensive. It also depends on age. Newer elevators have fewer faults and fewer parts to replace, so they are cheaper, 5000 feet per year. Those with long service life are more expensive, about 7000. Replacing large pieces such as wire rope is not included.
