Elaboração de plano de manutenção preventiva para uma pá carregadeira cat 924h de uma agroindústria em Teresina/PI

Abstract

In the current agroindustrial context, especially in the production of soybean meal and oil, heavy machinery is essential to ensure the efficiency and continuity of operations. In this regard, wheel loaders, which play a vital role in the handling of heavy materials, significantly contribute to productivity but require rigorous maintenance due to continuous use and the high demand for performance. This work presents the development of a preventive maintenance plan using the PDCA methodology and quality tools such as 5W2H and Ishikawa, which facilitate the identification of improvement points and the quick correction of problems, creating more precise maintenance procedures. As a result, it was possible to achieve outcomes by defining cost parameters and anticipating downtimes directly related to the execution of the loader's preventive maintenance plan, in addition to confirming the effectiveness of the equipment’s daily checklist, which helps provide an overview of the actual conditions of the loader. The study showed that the implementation of the preventive maintenance plan for the CAT924H Wheel Loader has been very effective. The creation of an efficient methodology, along with the application of a well-structured preventive maintenance plan indicating the equipment’s actual condition, ensured the beginning of a solid database and revealed possible improvement points for repeating the methodology cycle.
