Abstract (en)
[origin: WO2019222844A1] A system for removing contaminants from a surface, attached to a vehicle movable in a first direction. The system includes a first scraper for removing contaminants from a surface. A first conveyor system includes a continuous track element for conveying the contaminants removed from the surface in a second direction that is not aligned with the first direction. A second scraper removes contaminants from the surface and is positioned between the first conveyor and the vehicle. A second conveyor system is positioned between the vehicle and the second scraper and includes a continuous track element for conveying the contaminants removed from the surface in a third direction that is not aligned with the first direction. An ice and compact breaker is positioned between the first conveyor system and the second conveyor system. The ice and compact breaker includes a plurality of teeth for breaking the contaminants on the surface.
