    Plan de mantenimiento de herramientas y equipos de las siguientes áreas: taller de enderezado y pintura de vehículos livianos, taller de enderezada y pintura de vehículos pesados y taller mecánico multimarca de vehículos pesados de la agencia Mavesa Indoamérica ubicada en la ciudad de Ambato

    In the MAVESA INDOAMÉRICA agency, after having examined its current state, it was found that the list of tools and equipment was obsolete due to the recent modernization of these, thus generating certain errors in the handling of information on a daily basis and without having an updated maintenance plan. This evidenced the need for a technical project focused on maintenance. In this project, information on tools and equipment was collected, observing their current state and an updated inventory was generated, then codified technical data sheets and a maintenance statistic were elaborated by calculating times with information for the period September 2020 - August 2021, which allowed elaborating and interpreting the bathtub curve. Following the methodology of the NTP 679, the AMFE matrix was developed, allowing to specify the representative tool systems and equipment of the company, detailing their failure modes, root cause and effect, and then giving them a weighting to obtain the most critical ones, followed by the codified maintenance ranges. As a result, an annual preventive maintenance plan for tools and equipment was developed, organized with activities, frequency and duration for a whole year, and to complement it, a support program was implemented with the help of free software.

    Desarrollo de un plan de mantenimiento preventivo para el área de molienda de la empresa Molinos Miraflores S.A de la ciudad de Ambato

    The accelerated development of the industry and the high demand for products in less time have allowed the increase in the use of machinery and equipment, the same as representing an investment, require maintenance processes, in order to extend their useful life and guarantee its availability within the production line. For this reason, this technical document is developed, focused on mitigating the maintenance needs required by the machines that make up the grinding área of the Miraflores mills located in the city of Ambato, in order to carry out this study A bibliographic analysis was used together with a field study that allows us to determine both the mechanical and electrical components that make up the machines, all this in order to establish the elements that are highly prone to failure or causing them in a certain period of time. weather. Keywords: Maintenance preventive, Mills, Grinding, Miraflores, Matrix, FMEA, criticality, NTP, log, Maintenance range. Using both AMFE and criticality for the failure analysis, allowing the development of the logs and the maintenance ranges based on the concepts supported within the NTP 679, which detail and delimit the failure modes and the effects that the elements have within them. the processes used in order to identify and analyze possible failures.

    Desarrollo de un plan de mantenimiento para las máquinas de la empresa Planhofa C.A. mediante el mantenimiento productivo total (TPM)
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-03) Quezada Pedrera, John Manuel; López Velástegui, Jorge Enrique
    The purpose of this technical project is to introduce the philosophy of TPM (Total Productive Maintenance), to carry out a maintenance plan with a one-year projection of the most critical machines of the company PLANHOFA CA, based on the application of the 5S, global effectiveness equipment (EGE), autonomous and planned maintenance. The project establishes the necessary formats for maintenance management such as: technical sheets, work order, red card for unnecessary elements, machine inspection sheet and external services. The activities proposed for the maintenance of the most critical machines are proposed based on the manuals, historical data of each equipment, quantitative criticality analysis and the modal analysis of failures and effects, better known as AMFE, with which the critical components are obtained. On the other hand, a machine is chosen for the calculation and implementation of the overall effectiveness of the equipment, for which an Excel format is made to facilitate the calculations and interpretations thereof. The same that will serve as a pilot test to be applied to the rest of the machines if required by senior management. All maintenance activities are organized and classified in the range, to later translate them into the annual maintenance plan. Therefore, the applied maintenance philosophy can avoid as many unplanned failures as possible and thus be able to provide excellent quality products to the national and international market.
