ABSTRACT:
A powered system for removing large decals in the order of fifty feet or more comprises an upright, supporting frame ideally adapted for mounting upon a vehicle and a dynamic power head flexibly supported by the frame. A generally rectangular subframe is slidably coupled to the frame, captivated between a pair of vertically oriented stanchions. The subframe and the power head are vertically displaced with a hydraulic cylinder. An offset tilt mechanism mounted to the subframe dynamically mounts the power head. Preloaded springs extend between the vertically movable subframe and the tilting plate, which is pivoted to the subframe. A hydraulic cylinder deflects the pivot plate to an angle of attack that aligns the power head against the wall of the truck being serviced. The power head is preferably coupled to the tilting plate by fasteners that captivate suitable compensation springs. The power head comprises a rotary drum-like brush mounted driven by a hydraulic drive motor. Preferably the brush has approximately two hundred and sixty outwardly projecting rubber fingers arranged in a spiral pattern that forcibly remove the decal and adhesive. A roller assembly balances the power head as the brush is pressed against the decal. A concave reflector between the brush and the roller assembly comprises an electrically resistive heating element that supplies several thousand watts of radiant energy directed towards the decal under attack.
