Análise da implementação do programa 5S em um box de manutenção preventiva de caminhões fora de estrada

Abstract

Large organizations seek to increase their quality control of products and services through the implementation of methodologies such as the 5s - seiri, seiton, seison, seiketsu and shitsuke - that propose a more harmonious work environment, obtaining quality and productivity gains. In mining, the companies responsible for the maintenance of off-road trucks that transport large loads of ore, seek to perform more effective preventive maintenance, increasing the efficiency of their processes, and reducing the use of unnecessary resources. Thus, this study aimed to analyze the impacts of implementing the 5S Program in a preventive maintenance pit of offhighway trucks at the Carajás mine workshop, located in the southeast of Pará. The research is classified as applied, because the results were applied to the process and analyzed, with a qualiquantitative, exploratory and descriptive approach, based on a case study and action research. For its structuring, it was subdivided into three main stages: (i) mapping of the preventive maintenance processes and identification of the process issues, where a failure in the box layout was identified, tools arranged at approximately 20 meters; (ii) 5S implementation, working on the box layout standardization and (iii) analysis of the results obtained after the implementation of the improvements in the box layout. The results of the program application resulted in the reduction of the execution time of the preventive maintenance activities from 12 hours to 7.33 hours, with an approximate gain of physical availability of 2.52%. Besides this, improvements in the organization of the work area were identified, with a greater involvement from the collaborators. It was concluded, therefore, that the implementation of the 5S Program was important to increase the quality of execution of preventive maintenance, acting effectively in the organizationof the maintanence box.
