From bulldozers to school buses, fleets come in all shapes and sizes. No matter the type of vehicle or the size of your fleet, the experts at Liberty can provide maintenance for your fleet vehicles. Regularly scheduled inspections and preventive maintenance are key to keeping your fleet moving and avoiding costly breakdowns. Let our team help you create a maintenance schedule and keep your fleet in top condition.

Fleet Maintenance Theories & Definitions:

Reactive maintenance – “If it ain’t broke, don’t fix it”. In most situations this is not considered maintenance at all, but simply responding to failures as they occur. However, reactive maintenance can be the correct course of action for items that are not costly, failure prone, or critical for operation.

Calendar-based preventive maintenance – A recurring inspection or service scheduled based on specified time intervals.

Usage-based preventive maintenance – Actual meter readings (mileage/hours) are used to schedule inspections and services.

Predictive maintenance – Recommended repairs are scheduled based on historical data of failed parts on similar equipment in similar applications. Replacing certain parts before failure occurs can save costly down time and potential progressive damage.

Prescriptive maintenance using condition-based monitoring (CBM) – Similar to predictive maintenance, this maintenance plan will use sensors to measure certain conditions while equipment is operating. This data is collected and used alongside data mining software to help create the maintenance schedules, establish trends, predict failures, and even calculate the expected useful life of an asset.

To achieve optimal fleet maintenance it is often necessary to use a combination of all of these strategies. For example, we may use the reactive maintenance strategy to replace a failed marker light, calendar-based maintenance to schedule a DOT inspection, usage-based maintenance to schedule an oil change, predictive maintenance to recommend replacing fuel injectors, and condition-based monitoring to recommend replacing the air filter when the on-board sensor measures a high dust load. All of these could be included in the maintenance plan for the same vehicle!
