Maintain the elevator for several hours.

Generally speaking, it takes about 2 hours to maintain an elevator. If you work 8 hours a day, you can maintain 4 elevators a day. Usually elevator maintenance and repair are carried out together, and cleaning work is needed after maintenance. Moreover, safety preparation before maintenance is particularly important. After the elevator maintenance personnel arrive at the scene, they should first register with the management personnel of the property right unit, and learn about the normal operation of the elevator from the elevator management personnel of the property right unit, so as to focus on inspection during maintenance. Get the key to the computer room from the property management office and start the maintenance inspection one by one.
