Bucket rotation system for aerial tower

摘要

The present bucket rotation system can be easily and quickly interposed in the conventional mechanical bucket leveling system of an aerial tower and may be operated to immediately move the bucket from the normal vertical position to a horizontal position to facilitate removal of an injured workman, and/or to facilitate cleaning of the bucket. Hydraulic cylinders are interposed in the mechanical bucket leveling system and their operation imparts movement to the leveling system to rotate the bucket independently of movement of the boom sections.
