ABSTRACT:
A mudguard gritter that can be easily installed on trucks, school buses, delivery trucks and semitrailers. It can be fixed to supports of existing mudguards. The mudguard gritter comprises a container forming a hopper having the shape of a conventional aileron, with a top rectangular opening of 150 mm per 600 mm and a bottom opening of 25 mm per 600 mm. The top site has a door with hinges that make it possible to fill up the container with fine gravel. A rake supports eccentric vertical stems, which meet through an intermediate guide, at the bottom, on a mobile plate driven by a dual action cylinder powered by compressed air passing through a valve whose control is on the dashboard of the vehicle.
