The object of the research is a power plant of heavy-duty dump trucks and methods of diagnostics of its current state. Based on the analysis of experimental data on failures of elements and systems of the power plant the main elements, the analysis of which allows to determine the current state of the object of research are highlighted. The structural diagram of the dumper power plant is considered. The paper contains the results of the analysis of modern diagnostic methods and systems, allowing to estimate the current state of the power plant. The structure of monitoring system for the modern enterprise, which uses heavy duty dump trucks is developed. The peculiarity of the monitoring system is automation of processing of the received information and data base forming. The effectiveness of the proposed monitoring system is justified.
