Elevator accident cause identification can be analyzed from the following aspects:
1. Elevator equipment quality: Check the elevator equipment quality, such as whether the manufacturing quality of the elevator car, wire rope, motor, control system, etc. is qualified and whether it meets relevant standards and specifications.
2. Maintenance and maintenance: Check the elevator maintenance and maintenance records, whether maintenance operations are carried out on time, whether there are problems such as insufficient maintenance and non-standard on-site management. These are the main reasons for elevator failure.
3. Operator quality: Elevator operators need to hold the corresponding driver's license or operating certificate, and undergo relevant training and examinations. If the elevator operator is not skilled enough or operates improperly, accidents may easily occur.
4. External factors: External factors may also cause elevator accidents, such as natural disasters such as earthquakes, floods, fires, or man-made sabotage.
05. Equipment aging: Long-term use of elevators may also lead to accidents. For example, the elevator vehicle's reducer, hydraulic system, electrical equipment, etc. will wear or age due to long-term use, causing elevator failures and accidents. 12 The above are some of the main contents of the analysis of the cause of the elevator accident. Therefore, the elevator fault identification needs to comprehensively consider all factors. In practical applications, customized analysis needs to be carried out according to the specific situation. 3
