Abstract: A tire or caterpillar track washing facility system having a grid structure which is drivable upon by the vehicle to be washed and which defines a plane. The system includes a pair of longitudinal support structures which extends parallel to the plane and defines a central axis. A plurality of washing water pipes with nozzles supported on the longitudinal support structures extend parallel to the plane and transversely to a y-direction of the central axis. The y-direction of the central axis, an x-direction perpendicular to the central axis and parallel to the plane, and a z-direction of the surface normal to the plane define a Cartesian coordinate system. Nozzle axes are perpendicular to a pipe direction of the washing water pipes and inclined to the z-direction. The pipe direction of at least a part of the washing water pipes has a directional component in the y-direction.
