What a millwright does
Millwrights, known in Ontario as industrial mechanic millwrights, install, maintain and repair industrial machinery and mechanical equipment. Their work includes conveyors, pumps, compressors, gearboxes, hydraulic and pneumatic systems and production lines. They align shafts and couplings, replace bearings and seals, rig and move heavy equipment and carry out preventive maintenance that keeps unplanned downtime to a minimum and protects your production schedule.
In most plants, the millwright is the person called when something stops. Finch screens candidates for the equipment they have maintained, their troubleshooting approach, their skills in alignment, rigging, welding and hydraulics, and their 433A certificate status. We also discuss shift schedules and on-call requirements early, so the people you interview are ready for the way your operation actually runs day to day.
