The Impact of Operating Conditions on the Maintenance Interval of Trucks Equipped with a Computerized Maintenance Management System

In modern conditions, an increasing number of trucks and special construction and agricultural equipment manufacturers are using new computerized maintenance management system (CMMS) instead of maintenance system with rigidly set intervals for mileage or equipment operation in hours. The latter allow use of individually adjustable maintenance systems for equipment that determine maintenance intervals depending on actual load on equipment and its operating conditions. From point of view of work practice, there is currently insufficient information on the final results of these systems operation, depending on changes in operating conditions and modes of equipment use. The article analyzes data on 22 units of Mercedes-Benz Arocs and Mercedes-Benz Actros trucks for 180-250 ths.km. mileage and service maintenance on them, service intervals are shown, influence of operating conditions on them is analyzed, and mathematical models for assigning maintenance intervals are built.
