Elevator maintenance in the building is a significant process. It meets the standards following the state authorities.
What is elevator maintenance?
Elevator maintenance is the process of checking, maintaining, and ensuring the most stable operation of the elevator. Help detect early damage and technical problems inside the elevator and provide the fastest remedial measures. Do not affect the safety of users and avoid unfortunate risks.
Time of elevator maintenance
Depending on the life of the elevator and the frequency of use, there will be various maintenance times.
1. The life of the elevator
In the first year, the elevator needs to maintain once a month to ensure it works well.
After the first year of use, for the months the machine has a lifespan of 2–10 years, the reasonable frequency of elevator maintenance is every two months or less. If an elevator has been in use for more than ten years, it needs to preserve once a month to ensure it is safe.
2. Frequency of use
For the civil elevator uses in the office that have a lifespan from one to ten years, the reasonable maintenance period is every two months.
Commercial elevators in trade centers, buildings, and offices, are used continuously with large loads. The best maintenance time to ensure the elevator always works stably and safely is once a month.
In addition to elevator maintenance, the Investor/Building Management Board needs testing by Vietnam Safety Standards. After receiving a license to operate, the elevator must undergo safety testing every three years. In addition, the elevator has a life of 10 to 20 years, the testing is two years, and it is once a year if the life elevator is 20 years.
