Maintenance Guidelines
Active Attention from the Managing Body Is Essential
- Elevator maintenance is, in most cases, outsourced to a maintenance company.
- Due to time and location constraints, the maintenance company cannot handle day-to-day management.
- Active attention from the managing body or the safety manager is therefore essential.
Note Issues in Daily Use and Report Them at Inspection
- Make sure every issue, however minor, is reported and resolved.
- Minor issues are often missed during inspection, so notify the technician before the inspection begins.
Verify the Cause and Corrective Actions After a Breakdown
- After a breakdown is inspected, always confirm its cause and record and keep the details of the corrective actions.
- Most modern elevators resume operation simply by switching the control panel main power OFF and ON.
- Even minor faults can lead to accidents if their causes are left to accumulate.
Users Should Pay Attention to Maintenance Practices
- Many owners focus only on the monthly maintenance fee and try to sign a contract at the lowest possible price.
- Selecting a company that lacks technical capability and reliability shortens the service life of a high-value elevator.
- As elevators are complex and precise machines, sufficient technical expertise and dedicated equipment (software and special tools) are essential.
- It is important to always be aware of which maintenance company you are contracted with.
