Wadisson Quaresma

As a Maintenance Engineer, I am responsible for improving equipment reliability, developing maintenance plans, and optimizing maintenance processes across shredders, conveyors, gas-cleaning systems, Side-Well and Reverberatory furnaces, hydraulic and pneumatic systems, and dust-collection units. My role includes failure analysis, creation of inspection routines, continuous-improvement projects, cost-reduction initiatives, and predictive-maintenance management. Main Responsibilities: Lead RCA/RCFA activities and implement corrective and preventive actions to increase reliability and reduce downtime. Develop and update preventive maintenance plans and sensory inspection routines, including monitoring of noise, vibration, temperature, clearances, odors, and mechanical behavior. Create and optimize mechanical, sensory, and operational inspection routes with defined frequencies, methods, and acceptance criteria. Implement predictive maintenance practices such as vibration analysis, thermography, oil analysis, and condition monitoring. Coordinate improvement projects on shredders, conveyors, gearboxes, gas scrubbers, and Side-Well/Reverberatory furnaces. Evaluate asset performance using KPIs (MTBF, MTTR, availability) and develop engineering solutions to enhance equipment performance. Manage mechanical modifications, structural reinforcements, and design adjustments to increase robustness and safety. Provide technical support to maintenance teams during diagnostics, troubleshooting, and complex repairs. Prepare cost analyses, budgets, and ROI/feasibility studies for maintenance and engineering projects. Interpret technical drawings, OEM documentation, and mechanical specifications to ensure proper execution. Support procurement by specifying critical spare parts and assessing suppliers. Ensure compliance with safety standards, including LOTO, mechanical integrity, and safe-maintenance procedures.

Performed corrective, preventive, and predictive maintenance on industrial Shredder machines, vibrating screens/chambers, trommels, gas scrubbers, and material-handling equipment. Conducted maintenance on metal and rubber conveyor systems, including belt alignment, tensioning adjustments, drum replacement, bearing inspection, and structural wear assessment. Executed mechanical services on Side-Well and Reverberatory furnaces, focusing on feeding systems, refractory components, cooling circuits, and mechanical drive assemblies. Carried out troubleshooting and repairs on hydraulic and pneumatic systems, working with pumps, valves, cylinders, hydraulic power units (HPUs), regulators, and actuators. Maintained dust-collection and ventilation systems, including industrial fans, rotors, ducts, dampers, and bag-filter systems. Performed mechanical diagnostics using vibration monitoring, visual inspection, shaft/bearing assessment, dimensional measurements, and alignment checks. Read and interpreted technical drawings, OEM documentation, mechanical schematics, and equipment manuals for accurate execution of maintenance tasks. Supported continuous-improvement and reliability activities, optimizing maintenance routines, inspection routes, and equipment performance.

Performed industrial maintenance on polystyrene, polypropylene, and PVC extruders (binder and granulator types), including gearbox inspection, screw/barrel assembly services, heating/cooling circuits, and drive components. Conducted maintenance on cooling towers and crusher mills, including pump systems, rotating equipment, bearings, structural components, and water-distribution assemblies. Maintained and troubleshot pneumatic valves, instrumentation devices, vacuum pumps, exhaust fans, industrial blowers, and heat exchangers. Utilized precision measuring instruments such as calipers, micrometers, dial indicators, and other mechanical-inspection tools for dimensional verification and equipment diagnostics. Executed preventive, corrective, and emergency repairs, ensuring equipment reliability and compliance with safety standards (including Lockout/Tagout – LOTO). Interpreted mechanical drawings, schematics, diagrams, and OEM manuals to properly carry out maintenance tasks, disassembly, and reassembly of mechanical systems. Performed failure analysis, mechanical troubleshooting, alignment checks, and inspections of rotating and static equipment. Collaborated with operations and maintenance teams to improve equipment performance, reduce downtime, and support continuous-improvement activities.
