Residential elevators often encounter malfunctions after a period of use. However, these issues are not necessarily caused by the wear and tear or aging of machine parts, and the reasons for the malfunctions are varied. Therefore, maintenance personnel should identify the type of fault based on the elevator's issues and then proceed to resolve them.

Category of Elevator Malfunctions

Design, manufacture, and installation failures

Manufacturers with inadequate quality assurance systems have a gradual improvement process for the design, manufacturing, and installation of new products. After an elevator malfunctions, maintenance personnel should identify the location of the fault and then analyze the cause of the issue. If the fault is due to design, manufacturing, or installation, it is imperative not to act impulsively. Contact must be made with the manufacturer or installation/maintenance department, and their technical and installation/maintenance staff should collaborate with the maintenance personnel of the using unit to discuss and resolve the problem.

2. Operation malfunction

Operational failures are generally caused by users tampering with safety devices and switches. Such non-compliance with operational procedures inevitably leads to elevator malfunctions, even posing risks to passenger safety. This includes actions like bypassing the safety contacts of the door, operating while the door is open, and so on. We must prevent such failures from occurring.

Part Assembly Damage and Malfunction

These types of malfunctions are common and frequent in elevators, such as mutual friction in the mechanical transmission components, burning of contactors and relay contacts in the electrical part, overheating of resistors leading to burnouts, etc.

We must diligently avoid elevator accidents and the resulting harm to individuals. Additionally, we must prevent situations such as elevator shutdowns and reduced conveying capacity. Therefore, strictly adhering to elevator safety operating procedures and conducting thorough inspections on a regular basis are crucial measures to ensure the safe operation of elevators.
