<p>The invention relates to a washing vehicle (2), particularly for washing a curved tunnel wall. By causing a boom (12) to pivot in a vertical plane and by making the brush carrier (26) arranged on the boom (12) rotatable round a vertical shaft the washing brushes (35) can be set in any desired position. Each brush (35) is driven by its own hydro-motor (31). Washing liquid is fed from a single pump (96) to a distributor means (32). Washing liquid can hereby be carried up with a single hose connection (33). Achieved as a result of these steps is a maximum flexibility of the position of the brushes (35) relative to the tunnel wall.</p> |
