Content based on Brazilian standards (Ministry of Labour Regulatory Norms and ABNT). This is the second course in the Industrial Maintenance Mechanic training track; we recommend completing the introductory course, Industrial Maintenance Mechanic: Introduction, first. Here you deepen the technical and operational knowledge used daily in factory and industrial-plant maintenance. The course starts with the four pillars of maintenance — preventive, emergency corrective, predictive, and detective — and when to apply each strategy. Next, you study the hydraulic and pneumatic systems that drive presses, actuators, and production lines, understanding pumps, cylinders, valves, compressors, and compressed-air treatment. The last two tracks cover machine elements: bearings, shafts, and lubrication in the first, and gears, belts, chains, couplings, and brakes in the second. Each track pairs theory with practical shop-floor cases, preparing you to identify failures, read simple diagrams, and propose the right intervention. By the end, you will have the technical knowledge expected of a full-fledged industrial maintenance mechanic.
