Abstract
Abstract An apparatus for cleaning and spray painting pole structures. The apparatus includes a carriage constructed to be upwardly and downwardly movable along the axis of the pole to be cleaned or painted. Mounted on the carriage is a carousel rotatably secured so as to revolve around the pole as the carriage moves upwardly and downwardly. The carousel may be provided with brushes for cleaning the pole or with a paint sprayer for applying paint. In one embodiment two pairs of rollers are located symmetrically with respect to the sprayer and the poles so that the rollers evenly apply the paint to the pole and simultaneously minimize overspray losses.
