What Does Fleet Maintenance Do?
Fleet maintenance ensures that all the vehicles and trailers in your operation stay safe, reliable, and compliant. It includes scheduled services, repairs, and diagnostics tailored to the needs of your specific fleet. With regular upkeep, you reduce the risk of costly breakdowns, improve vehicle longevity, and maintain peak performance for your business.
What Is Fleet Service?
Fleet service is a structured program that includes maintenance, repair, and support for businesses with multiple vehicles. These services are designed to minimize downtime and maximize efficiency through proactive care and strategic planning. It’s especially useful for operations that rely on trailers and trucks for daily logistics, service calls, or transportation.
What Are the 3 Maintenance Categories?
Maintaining your corporate fleet involves three crucial maintenance categories: corrective, preventive, and predictive. Corrective maintenance, commonly known as repairs, focuses on fixing worn-out components and replacing parts as needed. Preventive maintenance revolves around setting up a regular maintenance schedule to prevent unexpected repairs and component failures. It encompasses essential maintenance items such as oil changes, filter replacements, fluid top-offs, tire checks, and battery load tests. Predictive maintenance is similar to preventive maintenance, though it employs cutting-edge forecasting technology and data analysis to anticipate maintenance requirements, allowing you to take proactive measures and optimize your fleet's performance.
