Resumen
As the demand for more sophisticated machinery has grown, so has the demand for their availability, leading companies to a more rational and productive use of production assets. In order to advance productivity with quality, maintenance is an essential factor, so that its role in large organizations is becoming more relevant every day. Preventive maintenance has a leading role, being responsible for preventing failures before they occur, ensuring productivity and providing savings to companies. This work aims to analyze the impacts and effects of preventive maintenance on productivity and maintenance efficiency in a vehicle fleet for heavy cargo transportation of CRIL Ambiental, through indicators of failure rate, availability and reliability. The research methodology is comparative, with the adoption of two scenarios to be characterized and analyzed: the first, without preventive maintenance control, and the second, after the control is applied. The comparison was made by implementing maintenance tools, creating a database for processing the information obtained, and then calculate the mean time between failures, mean time to repair, availability, and reliability indicators. With a 47.11% reduction in the mean time to repair and a 21.47% reduction in the failure rate, in addition to a 34.69% increase in the availability of the vehicle fleet, the results obtained demonstrate a significant improvement in the initial scenario after the implementation of preventive maintenance.
