Hydrodemolition machine for inclined surfaces

摘要

In accordance with the invention, there is provided a concrete removing apparatus for removing concrete from an inclined wall of concrete having a frame with a front region. The frame may be supported on either a platform or from the wall with the front region adjacent to the wall. A carriage assembly is coupled to the frame assembly proximate a front region thereof, the carriage assembly extending from one side of the frame to another. A nozzle assembly is mounted on the carriage assembly and operative to move laterally of the frame assembly in response to activation of the carriage assembly. A nozzle on the nozzle assembly is operative to emit a jet of fluid against the wall of sufficient velocity to remove concrete from the wall. A transporting assembly is coupled to and operative to raise and lower the carriage assembly.
