Small conventional bar racks often require manual cleaning with long handled rakes or pitch forks. This approach is not only labor intensive, but dangerous and often difficult to discern in remote areas when and how often the bar racks require servicing. Inadequate drainage through the bar racks can cause upstream flooding and/or create excessive velocities through the screens and cavitate down stream pumping equipment. Additionally, once a conventional trash rake has removed debris, a second debris handling system is required, adding to costs, complexity and maintenance. Conventional rakes have difficulty raking multiple bar screens requiring either a rake for each screen or complex, labor-intensive systems to traverse between screens or convey debris to an adjacent dumpster or remote location.
