Abstract
The expansion of services and technological equipment applied to the agribusiness sector grows year after year, e.g., tractors and agricultural machinery, which use systems shipped with sophisticated software that collaborate to aid, and optimize activities in the field. Maintenance of agricultural machinery, including tractors, is routine in the life of any farmer, especially the preventive and corrective maintenance. In this paper, the objective was to evaluate an alternative for the use of diagnostic software in the prediction of failures that may occur in the tractor clutch system. In this study, the PicoScope6 software was used to identify the failures in this system, and then, using the predictive maintenance phase, was compared with classic maintenance methods, allowed for estimating the necessary repair time. Results showed that software identified more precisely the mechanical components that presented failures. From the identification of failure components, a list of repairs and exchanges was estimated, and, when compared to the list of components generated by inspection without diagnostic software, the repair time was reduced by 88%, and the cost of repair in up to 93%. The availability of the equipment also increased as a result of the shorter repair time, thus maximizing the machine time in the field.
Highlights
The globalization of the last few years has made organizations increasingly dependent on their ability and speed to innovate, and improve their processes, thereby, always looking for continuous improvements
Maintenance has become one of the strategic functions and is responsible for the direct availability of assets. These assets can be described as the wealth that represents the elements that make up the monetary policy of an organization, such as: equipment, processes, procedures, human resources, investment capital, and raw materials
Predictive maintenance based on the use of diagnostic software made it possible to analyze in detail the points of measurement and identification of failures in the set of clutches of the tractor under study, allowing a more direct action on the cause of the problem
Summary
The globalization of the last few years has made organizations increasingly dependent on their ability and speed to innovate, and improve their processes, thereby, always looking for continuous improvements. The desire for competitiveness made the companies search for solutions that represent a way to achieve the status of excellence [2]. Maintenance has become one of the strategic functions and is responsible for the direct availability of assets. These assets can be described as the wealth that represents the elements that make up the monetary policy of an organization, such as: equipment, processes, procedures, human resources, investment capital, and raw materials. The aim for excellence and better results through maintenance is seen as an important resource of the organizations, whose results will improve and achieve a more effective Maintenance Management (MM) [3]. The MM of tractors and machineries [4] have gained a lot of attention due to advantages, e.g., reduction cost
