Desarrollo de un plan de mantenimiento preventivo, para la maquinaria del área de trituración de materiales pétreos en la empresa Jeal Construcciones

Abstract

The company does not currently have a preventive maintenance plan, so it uses a reactive approach, in which it waits for equipment to fail before proceeding to repair it. This not only generates interruptions in the company's production, but also increases the risk of occupational accidents, reduces the useful life of the equipment and generates periods of inoperability, since the machinery used in the process of crushing stone materials is important for the company's operation. This project was developed in several steps, the first one was to make an inventory of the machines belonging to the crushing area, then the critical equipment was identified and its current status was evaluated, also technical data sheets, FMEA and statistical matrices were made where the availability of the machines could be analyzed and the criticality and identification of components susceptible to failures were determined. Different ranges of maintenance were elaborated with activity guidelines with the objective of improving the performance and useful life of the machines and their components, knowing their reliability and availability; subsequently, preventive maintenance matrices were elaborated with different activities and the periodicity with which they were carried out throughout the year. Finally, fulfilling the objectives, the maintenance plan was uploaded to a specialized software, with the objective of automating maintenance tasks and improving the efficiency and productivity of its processes and personnel.
