The invention relates to a friction snowplough comprising a device having a parallelepiped shape and a heavy weight, designed to remove snow that forms on asphalt in extreme weather conditions and situations. The operation of the snowplough is based on friction between two moving bodies. The work required to move the two bodies is transformed into heat energy which is absorbed by the ice, melting same. The heavy weight takes the form of a regular hexahedron (1) of which: the front part forms an acute dihedral angle (2) that is equipped with a securing element (3) that can be coupled to the tractor vehicle: and the rear part comprises a transverse hitch embedded in the heavy weight and having at least one roller (5) assembled thereto. |
