Abstract A machine for cleaning a surface by means of high pressure jets of liquid comprising a frame for mounting on a vehicle, a manifold on the frame, a plurality of lances in communication with said manifold, a plurality of nozzles in said lances for supplying fan-shaped jets of liquid for impingement on said surface to be cleaned, said nozzles being oriented to cause the jets to be inclined at an acute angle to the direction of motion of said vehicle and being proximate each other so as to clean a swath on said surface as said vehicle traverses said surface, and adjustment means for adjusting the inclination of the lances relative to the vertical and for adjusting the orientation of said nozzles relative to the direction of travel of said vehicle, and a plurality of pump units for supplying high pressure liquid to the manifold. The foregoing machine is used in a system which includes a source of water and a plurality of motor-pump units placed in parallel across the machine and the source for producing a sufficient quantity of water at a sufficiently high pressure for supplying the above described machine.
A system for cleaning large surfaces by means of large quantities of high pressure water from a source of water under relatively low pressure comprising a plurality of pumping units for raising the pressure of said water, first conduit means for effecting communication between said source and said plurality of pumping units, a vehicle, a manifold mounted on said vehicle, a plurality of nozzle means mounted in adjacent relationship on said manifold for producing a plurality of jets for cleaning a swath on said surface as said vehicle traverses said surfaCe, and a plurality of second conduit means for effecting communication between said pumping units and said manifold.
