Project Machinery Operators work with various types of heavy machinery, much of which is used on construction sites, for paving roadways, and for the destruction of buildings and other structures. Responsibilities vary by project; however, the key responsibilities of a heavy equipment operator are to control and operate equipment that moves earth, freight and other materials.

Heavy equipment operators are in charge of driving and controlling different pieces of heavy equipment for construction projects. Some of the most common types of heavy machinery are cranes, bulldozers, backhoes, graders, dump trucks and pavers. Although many heavy machine operators are trained in the use of several pieces of equipment, some tend to focus on one type of heavy machinery.

For instance, someone who operates a backhoe may alternate between the backhoe and a bulldozer. Along with operating the equipment, heavy machine operators maintain the equipment and ensure the project area is safe, abiding by the strict guidelines and procedures put in place by the Occupational Safety and Health Administration as well as their project foremen.
