What does a millwright do?

Reads technical documents

Millwrights interpret blueprints, schematics, equipment manuals, installation specifications and work orders. They use this information to determine dimensions, tolerances, sequences and safety requirements.

Prepares the work area

Before moving equipment, they inspect the site, identify hazards, verify foundations and plan how parts will enter the space. Preparation may include permits, lockout/tagout procedures and coordination with other trades.

Moves and positions machinery

Heavy components may require cranes, hoists, jacks, dollies, forklifts or other rigging equipment. Millwrights calculate or verify loads, select appropriate equipment and guide machinery into position according to the approved lift plan and site rules.

Assembles and installs equipment

They fit components, secure equipment to foundations, connect mechanical systems and follow manufacturer specifications. The work must account for clearances, orientation and access for future maintenance.

Aligns and levels machinery

Precision alignment reduces vibration, wear and premature failure. Millwrights may use levels, dial indicators, laser-alignment tools, micrometers and other measuring instruments to position shafts, couplings and components accurately.

Inspects and tests systems

After installation or repair, millwrights check clearances, lubrication, guards, fasteners and operating conditions. They may participate in controlled startup and observe sound, vibration, temperature or performance.

Troubleshoots mechanical problems

When equipment fails, a millwright gathers symptoms, reviews history and tests likely causes. Problems may involve bearings, belts, gears, couplings, seals, lubrication, alignment, hydraulic components or structural supports.

Repairs or replaces parts

The tradesperson dismantles equipment, inspects components and replaces damaged parts. Work may include fitting bearings, repairing drive systems, fabricating a bracket or coordinating specialized machining.
