  • the device can be operated in a horizontal but also in a vertical position.
  • a particular advantage of the washing device is that, after its simple and rapid attachment to the front boom, it can be operated in one-man operation from the driver's cab of the drive vehicle.
  • the carrier and the anchoring of the front boom are connected by a rope which is guided over a rope guide running in the plane of the front boom.
  • the rope guided in the plane of the front boom ensures that the washing device in its horizontal working position always remains substantially horizontally independent of the respective pivoting position of the arms of the front boom.
  • the carrier is only as; Entirely deflectable from the level of the front boom, so that damage to the traffic sign due to excessive pressure and canting of the washing device from the level of the traffic sign are avoided.
