Optimización del rendimiento de la mini cargadora XCMG, modelo XC740K, de la Carrera de Ingeniería Automotriz, mediante la implementación de estrategias integrales de mantenimiento preventivo

Abstract

The present project, titled "Optimization of the performance of the XCMG mini loader, model XC740K, from the automotive engineering program, through the implementation of comprehensive preventive maintenance strategies," focuses on improving the efficiency and durability of heavy machinery in the educational field. The XCMG XC740K mini loader, acquired in 2023 by Universidad Politecnica Salesiana, is used in the Heavy Machinery and Diesel Injection Systems course to provide students with both theoretical and practical training. The main objective is to implement a preventive maintenance plan based on the Total Productive Maintenance (TPM) methodology to ensure the continuous operability of the mini loader, reduce downtime, and minimize occupational hazards. Specific objectives include the development of a preventive maintenance manual, a cost analysis of the service, the acquisition of spare parts, and demonstrating the importance of using quality spare parts. The project methodology was based on an exhaustive qualitative and quantitative analysis. It began with a review and diagnosis of the current state of the machinery, followed by the implementation of a structured maintenance plan, designed according to the manufacturer's recommendations and best practices in preventive maintenance. The comparative analysis of high and low-end filters, using tools such as ImageJ and MATLAB, demonstrated the superiority of high-end filters in terms of filtering capacity and durability. These filters showed a superior structure, allowing for prolonged service life and better performance in protecting critical systems of the machine, such as the hydraulic system, the engine lubrication system, air intake, and fuel supply. This project demonstrates that well-structured preventive maintenance practices and the use of quality components are essential to maintain the operability and efficiency of machinery in an academic environment, providing complete and high-quality training to automotive engineering students.
