What Millwrights Do

Millwrights install, dismantle, repair, reassemble, and move machinery in factories, power plants, and construction sites.


Millwrights typically do the following:

Millwrights are highly skilled workers. Putting together a machine can take a few days or several weeks. Millwrights need to have a good understanding of how the machine works so that they can repair it when it breaks down. Repair includes replacing, as needed, worn or defective parts of the machinery.

Millwrights also may be involved in taking apart existing machines, a common situation when a manufacturing plant needs to clear floor space for new machinery. Breaking down a machine is usually as complicated as putting it together. Each part must be carefully taken apart, categorized, and packaged for shipping.

Millwrights use a variety of handtools, such as hammers and levels, as well as equipment for welding, brazing, and cutting. They also use measuring tools, such as micrometers, levels, measuring tapes, lasers, and other precision-measuring devices. On large projects, they commonly use cranes and trucks. When millwrights and managers determine the best place for a machine, millwrights bring the parts to the desired location using forklifts, hoists, winches, cranes, and other equipment.
