As an excavator operator, you control the heavy equipment that moves dirt, sand, and other materials on construction sites. In addition to operating the excavator machine, your job duties are to perform routine maintenance on your excavator and coordinate with your supervisor for major repairs. Since your heavy machinery will move earth, rubble, and debris around the construction sites at your jobs, you need to communicate with the site supervisor and other construction workers to ensure everyone’s safety while you’re operating the excavator.
