Industries & Professions /
Operating engineers work for a variety of construction companies as well as manufacturers and state agencies. Whatever the employer, operating engineers run power shovels, cranes, derricks, hoists, pile drivers, concrete mixers, paving machines, trench excavators, bulldozers, tractors, and pumps. They use these machines to move construction materials, earth, logs, coal, grain, and other material. Generally, operating engineers move the materials over short distances: around a construction site, factory, or warehouse, or on and off trucks and ships. They also do minor repairs on the equipment, as well as keep them fueled and lubricated. They often are identified by the machines they operate.
