Definitions

  • the invention relates to a device for clearing, in particular for cleaning, traffic areas such as roads, highways and airstrips, snow, slush, water, dirt, dust or the like, with a movable support frame, in which two rotatable drums are stored, around which a conveyor belt for the goods to be cleared can be guided in the operating position, diagonally or transversely to the direction of travel.
