Melhoria na segurança operacional na translação do carro posicionador do virador de vagões do porto multiusuário de Nacala-à-Velha – Nacala Logistics/CLN

Abstract

During the peak of about 4 months in a professional internship at Nacala Logistics/CLN in the Port Maintenance Management, specifically supervising Inspection and Structural Integrity as an Electrical Inspector; it was possible to identify points of improvement and develop them with a view to improving safety in port operations. In this work, in addition to the report on the activities during the internship, one can also follow the improvement project carried out in operational safety in translation in the Wagon Positioning Car of the Multi-User Port of Nacala-à-Velha. Before exploring specifically Wagon Positioning Cars, there was a need to generically address the processes of unloading and loading mineral coal from exploration in the district of Moatize in Tete. In the survey carried out on the equipment and/or machines of the Multi-User Port of Nacala-à-Velha, it was found that almost all machines are equipped with instruments that help in the automation of operational movements and, above all, in the safety of operations. The safety of the translational movement is monitored by sensors and limit switches, except in the Positioning Car where it only had limit sensors, subsequently removed therefore, they were not effective during operations, which leads to the proposal of assembling limit switches to monitor and guarantee operational safety in its translational movement. Based on what has been noticed in other machines, limit switches prove to be effective, because unlike sensors, as they are physical, they guarantee the closing or opening of the circuit according to the need.
