Millwrights are highly skilled workers whose primary function is to install heavy machinery. When machinery arrives at the job site, it must be unloaded, inspected, and moved into position. For light machinery, millwrights use rigging and hoisting devices such as pulleys and cables to lift and position equipment. For heavier jobs, they are assisted by hydraulic lift-truck or crane operators. To decide what type of device is needed to position machinery, millwrights must know the load-bearing properties of ropes, cables, hoists, and cranes.
