Claim 14:
15. A scraping device for cleaning a roadway surface, the scraping device having a right side, a left side and a lowermost edge, the scraping device including:
a central support having a front surface;
two opposing lateral wings forming the right and left sides of the scraping device, each wing having an inner edge, an outer edge and a front surface, each wing extending along a horizontal axis in a lateral direction between the inner edge and the outer edge, the inner edge of each wing being configured to pivot about a vertical pivot axis provided on a respective lateral side of the central support, the front surfaces of the central support and that of the two opposite wings forming together a continuous front surface of the scraping device, each wing including:
an upper section through which the wing is attached to the vertical pivot axis, the upper section having a lowermost edge;
a bottom section pivotable relative to the upper section about a horizontal pivot point, the horizontal pivot point being located at a position that is adjacent to the vertical pivot axis and also adjacent to the lowermost edge of the upper section, the bottom section of each wing including:
a first subsection through which the bottom section is pivotally attached to the upper section, the first subsection remaining parallel to a corresponding part of the upper section when the bottom section is pivoted about the horizontal pivot point, the first subsection having a lowermost edge; and
a second subsection positioned below the first subsection;

an actuator mounted between the central support and the upper section of the wing to pivot the wing about the vertical pivot axis; and
a first force-generating mechanism mounted between the upper section and the bottom section to exert a first return force along a transversal axis that intersects the horizontal axis urging the bottom section downwards with reference to the upper section, wherein the first force-generating mechanism extends along the transversal axis that intersects the horizontal axis.
