Predictive maintenance: how to prevent machine downtime before it happens

The problem with reactive maintenance

For years, industrial maintenance has followed a simple approach: intervene when something breaks. This model — known as corrective maintenance — has very high hidden costs: unplanned production downtime, emergency labour, spare parts purchased urgently.

Industry data estimates that one hour of downtime on an average production line costs between €5,000 and €50,000, depending on the sector.

What is predictive maintenance

Predictive maintenance uses data collected in real time — vibrations, temperature, electrical absorption, operating hours — to predict when a component is about to fail, intervening before it happens.

This approach should not be confused with calendar-based preventive maintenance (which involves scheduled replacements regardless of the actual state of the component): predictive maintenance is more precise and generates less waste.

Measurable advantages

\- Reduction of unplanned downtime by up to 80% in well-monitored plants

\- Increase in machine lifespan by 20–40%

\- Reduction of maintenance costs by 10–25% compared to preventive maintenance

\- Better planning of technical resources and spare parts

How to implement it

A predictive maintenance programme typically develops in three phases:

  1. Initial assessment: analysis of plant condition, identification of critical points, definition of parameters to monitor
  2. Instrumentation installation: IoT sensors, data acquisition systems, connection to the monitoring platform
  3. Intervention plan: definition of alarm thresholds, intervention protocols, technical staff training

The role of the technical partner

Implementing such a programme requires both plant engineering skills and data analysis capabilities.
