Aplicação de ferramentas da qualidade e de análise de dados de telemetria: um estudo de caso em escavadeira hidráulica

Abstract

In industrial processes, quality management tools are used to ensure efficiency. The use of industrial statistics together with data from control and telemetry systems helps engineers in decision-making, with the objective of achieving product quality or improving performance indicators. Techniques such as PDCA (Plan, Do, Check, and Act) provide a robust structure for implementing improvements. In the present study, a process is improved using these tools. Telemetry data from a hydraulic excavator operating in ore loading are analyzed. A continuous improvement action using the PDCA cycle is implemented to impact three fundamental aspects of the operation: consumption, performance, and sustainability. After implementation, it was possible to reduce the annual fuel consumption cost of a single piece of equipment by approximately R$ 2.646,00. With the expansion of the improvement to the equipment fleet, savings can reach R$ 31.752,00 per year. Another outcome was the reduction in the operation cycle time, which decreased by up to 51.04% after the implementation of the process improvement. Finally, it was also possible to achieve an average reduction of 2.03% in the equipment’s emission rate between the adoption and implementation phases of the proposed procedure.
