Annual operating cost of an 8-story elevator

4k to 5k or 7k to 8k. An elevator needs maintenance within 15 days at most. An 8-story residential elevator will cost about 4,000-5,000 yuan/set/year after one year, which is small in number and remote in location. The later maintenance cost of elevators will rise to 7000-8000 yuan/set per year.
