EM – 50-50 is the ratio that determines the quality of the elevator in the opinion of many industry experts. 50% comes from the quality of components and equipment and 50% from maintenance services will determine product quality. This homelift maintenance information will most likely be useful to you.
National technical regulation QCVN 32:2018/BLDTBXH on occupational safety for homelift clearly stipulates: “Elevators during use must be periodically maintained for no more than every 3 months. In between maintenance, it is necessary to check and promptly deal with possible hazards.” The process of using the elevator needs to comply with the above standards of the Ministry of Labor, Invalids and Social Affairs, elevator experts also recommend periodic maintenance once a month.
In addition, the elevator is a moving device associated with human safety, so the elevator maintenance is directed to checking the entire elevator, ensuring that the parameters are up to standards, so that the elevator always operates in the right state, avoid possible damage, prevent problems related to safety of use.
Professional elevator maintenance procedures must be performed as follows:
– In the case of special elevators, the inspection will be carried out according to the mandatory requirements of the manufacturer.
Accordingly, the process needs to be carried out synchronously and fully with the following steps:
Well-trained technicians: It is advisable to find elevator companies that provide the entire team from installation to operation, maintenance and product maintenance. A reputable elevator maintenance company will have a detailed elevator maintenance process, all technicians are professionally and periodically trained by technical experts from Vietnam and abroad.

Ensure security – safety: When we hire elevator maintenance services, it means that the appearance of strangers in the house is a constant concern for homeowners. Therefore, the following suggestions will limit the risks for your family.
– Hire the elevator service of a unit with high capacity and reputation.
– Arrange someone to supervise the technician’s working process.
– Technicians performing maintenance work should have all the most basic requirements: Employee card with work assignment slip of the service provider with stamp; full protective clothing and equipment; required to present citizen identification to compare with the assignment documents or not. If the homeowner is in doubt, it is necessary to immediately verify the information with the service provider before letting the technician into the home.
In the coming time, when the government requires mandatory practice certificates (for occupations related to safety, health, …), technical staff are required to present certificates or can scan QR codes to check and compare personal identity, maintenance and repair work on the data management system.
Request to try the elevator rescue feature: The automatic rescue function (ARD – Automatic Rescue Device) is a must-have safety function, in case of sudden power failure, the elevator brings the cabin to the nearest floor. for the user to log out. But in fact, this device may be damaged, the battery is out of power, … but the owner does not know. To check if this function works normally, when taking over for maintenance, you must ask a technician to suddenly cut off the power to perform a hypothetical case, to see if the cabin is brought to the nearest floor or not.
The modern elevators also integrate the SRS (Self Rescue System) system in case the power fails, the ARD rescue unit fails, passenger can press the SRS button to free himself without outside help. To test this system, you assume a power failure and request to disconnect the power of the automatic rescue unit (ARD) to press the SRS button in the cabin to see if the cabin automatically returns to the nearest floor normally.
Requirements for testing emergency rescue system: Standard elevators have an internal communication system (Intercom) to ensure 3-point communication: People in the cabin, people outside the duty room and the machine room electrical cabinets. This system is only effective for public elevators that are always pedestrian or have security guards on duty. But for homelift, this system is less effective when people at home alone using the elevator are locked, even if they call, no one will listen.
To overcome this situation, some elevator companies have recently provided the Emcall (Emergency Call) emergency call system. This system can perform the following functions:
– Automatically send errors to the service center by message.
– When the stairs are locked alone, just press the Emcall button in the cabin, the call will be automatically transferred to 5 phone numbers that you choose to set up (for example: 3 family numbers, 2 numbers of service provider or emergency number 114). As soon as you press the button, the Emcall system will automatically dial the first number, if no one picks up after 10 seconds (or according to the set time), it will automatically switch to the second number and repeat until someone picks up and come to rescue.
Emergency lights, ventilation fans: When the power goes out, the ventilation fans and emergency lights in the cabin must operate for at least 30 minutes to ensure light and air circulation. Therefore, you ask the technician after the maintenance is done to let you check this function by standing in the cabin and cutting off the total power to see the status of the system.
Maintenance minutes and inspection deadlines: After the maintenance session is over, you ask the technician to re-submit the minutes to check, if you are satisfied with all work items, then proceed to sign for confirmation. You have the right to question the contents of the work and the status of the minutes.
