Abstract
A fluid containing insulated tank is mounted on a vehicle chassis having an engine driving a hydraulic system and an electric energy generating unit. The roadway cleaning apparatus, including housing contained screw conveyors, is mounted transversely of the forward end of the vehicle chassis for discharging snow and roadway debris through discharge tubes into the tank through an inlet port opened and closed by a hydraulically operated inlet port opening and closing door. Electric resistance heaters, contained by the tank and mounted thereon, melts snow and heats fluid and air contained by the tank. An agitator within the tank forms a slurry of the contents.
