The importance of maintenance
The elevator is a "comprehensive facility" in which more than 20,000 components are assembled precisely by the combination of electric / electronic / mechanical / construction technology, and it carries an unspecified number of people. This will ensure the safety of the user and will save the overall cost of elevator management.

7. Guarantee of non-operating time at the time of fault repair
8. Guarantee of emergency dispatch time in confined accident
9. Whether you have insurance coverage to guarantee liability for damages

12. 성능
    • ㉠ Vibration: When the elevator is running, it means the shaking in the car..
    • ㉡ Noise: Noise in car, platform or living room when the elevator is running.
    • ㉢ Conception accuracy: height difference between car floor and platform floor when elevator is stopped
    • ㉣ Speed: refers to the speed at full speed. (For example, 60 m / min). (예 : 60m/min)
    • ㉤ Function: General movements and indicators that the elevator should perform.
