/kloc-how much can an elevator in a 0/6-story building cost a year? How often do elevators need to be repaired and maintained? How much is it each time?

There are several kinds of maintenance, including half-package, clear-package and full-package. Half-package means that the maintenance company can replace accessories at a certain price for free, usually around 300 to 450 yuan in January. Clear package means that all the elevator parts are bought by the property when they are broken, and all the elevator parts are replaced free of charge by the maintenance company, but the maintenance premium in January is higher, generally around 800 to 1000 in January. You can calculate the maintenance fee for one year by yourself. The state has regulations that maintenance must be done every two months. Because you paid the maintenance fee, every maintenance is free. Please adopt it.
