Unusual noise levels generated by the step band or handrail. Changes in braking distance or speed inconsistencies. Elevated temperatures in key components such as the handrail or drive station. Vibration detected on the gearbox, indicating potential instability. Any deviations from standard operating parameters as monitored by predictive maintenance systems.,Escalator predictive maintenance uses sensors to track and gather actionable data on various escalator components and behaviors. By monitoring these indicators, potential issues can be identified early, enabling proactive escalator maintenance interventions to prevent escalator failures and ensure continued smooth and safe operation.
