Elevator Maintenance Standards

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. 

The article on elevator maintenance in Taisei VN 

The elevator maintenance includes checking the article:  

1. The operation of the controller in the machine room 

• Recharge mode of the elevator rescue device 
• Pulley and steel cable situations 
• Speed limiter, relay, contractor 

2. Engineer system 

Because the elevator motor bears the load of the entire cabin, it is necessary to check factors such as: 

• The quality and oil level in the engineer 
• The governor 
• The speed of the engineer 
• The capacity 

3. Counterweight guide rails 

• Guide rail fish plate 
• Link rail to bracket, bracket to wall, weld rail 

4. Cabin linkage system 

• Car roof, counterweights 
• Wire rope clips 
• Ventilators 
• Upper travel switch 
• Gearless traction elevators, oil rail quality of cabin counterweight 
• Cable tension 

5. The lighting and contact in the cabin 

• The lighting system in the cabin always ensures to provide enough continuous light for users. 
• The bell, Intercom, and photocell are always in working condition. 
• Check the cabin door guide grooves, door clearance 

6. Quality of operation of the door system 

Check regularly to ensure user safety: 

• The dashboard 
• Door sill 
• Door lock 

7. The elevator operation 

• Operational quality of the elevator system 
• Quality of the rescue system 
• Elevator stop and run speed 

Elevator maintenance standards 

• Elevator maintenance ensures safety requirements for elevator construction and installation according to standards TCVN 6395-2017. 
• Testing ensures adequate protective tools, support for disassembly, and inspection according to standards TCVN 6904-2001. 
• For hydraulic lifts, the maintenance needs to meet the standards TCVN 6396-1998. 
• Test methods with hydraulic lifts have strictly adhered to the standard TCVN 6905-2001. 
• Safety requirements for installation and use are applied according to the standard TCVN 7628-2007. 
• Elements related to the cabin, and guide rail must comply with the standard TCVN 5867-1995.
