To get a heavy equipment operator per diem job, you need to be licensed to handle large machinery. Licensing requirements vary by state and depend on the type of equipment that you operate. For example, heavy box trucks require the driver to hold a commercial driver’s license (CDL). There are no formal education requirements for this position, though most have at least a high school diploma or equivalent. You may take training courses through a vocational school or acquire an apprenticeship with a construction contractor or trade union. Some start their careers with an entry-level position at a job site and shadow heavy equipment operators to learn how to maneuver large machines and work their way up to per diem jobs.
