Implantação da manutenção centrada na confiabilidade em uma ponte rolante de movimentação de bobinas

Abstract

This project presents the application of the Reliability Centered Maintenance methodology in a coil handling crane at ArcelorMittal Vega. The objective is to use the RCM to review the current maintenance plan for this equipment, as well as to disseminate the methodology in the maintenance team and also serve as a pilot project to be replicated in the company's other overhead cranes. In order to carry out the studies, the RCM methodology defined in the Company's Maintenance Management Plan was used, which contains all the RCM steps, tables and classifications of failure modes. The equipment manuals, history of failures and team experience were also used for the study. The study was completed until step 6 of the RCM and will continue with the other steps according to the implementation schedule. Until the end of this stage of the study, all failure modes, their criticality classification, the effective maintenance tasks to be applied, the periodicity and the grouping of these tasks were determined. The new maintenance plan became more effective because it was developed using the RCM methodology. The implementation team had during the development of the work a great evolution in the concept and the application of the methodology. Based on the quality and evolution of the work carried out as a pilot in the GH2 crane, the study will be replicated for the other existing cranes in the company, after completing the other phases of the implementation.
