  • Page 15: Sweeping System

    SWEEPING SYSTEM ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ FUNCTIONAL OVERVIEW The 2060 / SR 1800 sweeper has a forward-throw or dustpan designed sweeping system. In a forward throw design the broom is made to rotate in such a direction that it will sweep the dirt and debris forward into a front-end hopper. The broom is driven by a drive lug assembly, which is a lug mounted on a hydraulic motor, located on the left side of the broom housing.

  • Page 16: Main Broom Maintenance

    SWEEPING SYSTEM ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ MAIN BROOM MAINTENANCE Since the Main Broom Motor always turns in the same direction, the bristles on the broom eventually become curved, reducing sweeping performance. Sweeping performance can be improved by removing the broom and turning it around (end-for-end). This procedure, known as “rotating”...
