Predictive maintenance

Definition

Predictive maintenance is a proactive maintenance strategy that uses data analysis and monitoring techniques to predict when equipment failures might occur. By analyzing trends in performance data, this approach allows for timely interventions before breakdowns happen, minimizing downtime and reducing repair costs. This method often leverages advanced technology, including computer-aided vibration analysis software, to assess equipment condition and inform maintenance decisions.
