Plan de mantenimiento preventivo para la maquinaria pesada y vehículos livianos del gobierno autónomo descentralizado municipal del cantón San Cristóbal de Patate

Abstract

The present research work has been developed taking into consideration the needs of the public institution GADM Patate, focusing on heavy machinery and light vehicles of the automotive park of the institution, in order to provide a practical tool for the performance of maintenance activities within the mechanical workshop that allows to improve the availability of equipment for the development of field work of both heavy machinery and light vehicles and therefore also extend the useful life of the same. As a starting point of the research project, once the data processing of the history of the mechanical workshop of each machinery and light vehicle has been carried out, the calculation of maintenance indicators such as the average time between failures, average repair time, failure rate, stop rate and availability has been carried out, which as a starting point allows to know the current status of each unit of heavy machinery and light vehicle of the GADM Patate automotive park. To determine which mechanical components are more likely to suffer failures or damage, the modal analysis of failures and effects (AMFE) has been carried out, endorsed by the NTP 679, which indicates within its content the guidelines for the application of this methodology in equipment. The critical components have been characterized by calculating the risk priority index, the norm mentions that the components assigned with a rating greater than 100 will be considered critical and intervention or prevention actions must be taken. The maintenance plan is made up of a maintenance log where the preventive maintenance activities are detailed considering the critical and main components that make up the heavy machinery and light vehicles, within the maintenance log the machine, systems, components, maintenance activities, frequency in which the activities should be carried out are also detailed. In this way, maintenance tasks have been scheduled for one year of operation, all this in order to improve availability and keep machinery and vehicles in good condition
