  • Patent number: 10570575
    Abstract: A surface, e.g., a concrete surface, is worked by guiding a lance (23) which comprises a water jet mouthpiece (27) coupled to the high-pressure water over the surface in a working path and at the same oscillating the lance transversely to the working path. The oscillation is driven by an eccentric mechanism (30, 31) and has a stable eccentric position when the mechanism is rotated in the one direction and a stable eccentric position when it is rotated in the other direction. The two positions have a different eccentricity and impart different widths to the working. The working depth and the working width can be changed by changing the direction of rotation.
