摘要: The device includes two opposing lateral wings forming the right and left sides of the scraping device. Each wing includes an upper section through which the wing is attached to the central support about a vertical pivot axis, and a bottom section that is pivotable with respect to the upper section about a first horizontal pivot axis. Each wing can follow the unevenness of the roadway surface and may also include parts that can pivot backwards in case of a frontal impact with an obstacle. The scraping device offers a very high degree of versatility and can clean various kinds of roadway surfaces with an unprecedented level of efficiency.

摘要: A blade assembly may include a blade and a wing. The blade may be configured to be pivotably attached to a machine. The wing may be pivotably attached to an end of the blade to adjust a width of the blade assembly. The wing may be movable relative to the blade over a range of motion that is greater than 180 degrees.
