Self propelled vehicle's variable base washing ramp for cleaning gutter in road, has nozzles spraying liquid/water jets, and extensions placed at ends of central main ramp and pivoting around axes perpendicular to direction of main ramp

摘要

The ramp has spray nozzles (13) for spraying pressurized liquid or water jets (14) on a cleaning zone. Extensions (3, 4) are placed at ends of a central main ramp. The extensions are pivoted around axes perpendicular to a direction of the main ramp from a position in which the extensions are in alignment of the main ramp, to a position in which the extensions are folded parallel to the main ramp. The pivoting of the extensions is controlled from a driver compartment of a self propelled vehicle.
