Predictive maintenance (also known as proactive maintenance) is a strategy for maintaining the health of vehicle or machinery fleets. It involves monitoring current operational parameters to identify early signs of potential malfunctions. This approach enables timely repairs and the replacement of consumables as needed.
As a proactive technical maintenance method, predictive maintenance offers a promising alternative to scheduled maintenance, which is performed at predetermined intervals set by internal fleet regulations, regardless of the actual condition of parts and mechanisms. In contrast, the goal of predictive maintenance is to determine the precise moment when maintenance is required. This ensures the smooth operation of machinery and helps reduce the operational costs for vehicle or machinery owners and operators.
Areas for Implementing Predictive (Proactive) Maintenance
Predictive maintenance is particularly suitable for advanced (complex) machines that operate in challenging conditions, where it is difficult to manage fuel consumption and the wear of engines or other components. Examples of such advanced machines include:
- Mining and quarrying equipment
- Construction machinery
- Specialised vehicles for oil and gas extraction
- Railway equipment
- Water transport
- Diesel generators
- Power plants
Benefits of Predictive Maintenance
Considering the high cost of complex machinery and the fact that maintenance can account for up to 50% of total fleet operating expenses, employing 24/7 real-time remote equipment diagnostics and implementing predictive maintenance can significantly reduce overall fleet costs. The key benefits include:
- Reducing Downtime Risks: Minimizes the likelihood of unexpected breakdowns and equipment failures.
- Extending Machinery Lifespan: Promotes careful operation that enhances the service life of the equipment.
- Optimizing Maintenance Efficiency: Ensures that the technical team is prepared for work in advance, streamlining maintenance operations.
- Improving Fuel Economy: Maintains fuel efficiency by preventing increased consumption linked to worn fuel filters.
- Cost Savings on Spare Parts Replacement: Avoids unnecessary servicing of components that still have remaining operational lifespan, reducing spare parts expenses.
