ABSTRACT:
A mobile self-propelled apparatus for automatically progressively sandblasting over a surface, of the type having a platform upon which is mounted a swinging boom arm having a head at the end thereof to support a sandblasting nozzle. The swinging boom arm is mounted on a drive wheel driven by a first pneumatic cylinder for movement about the axis of the arm. A second pneumatic cylinder operates to cause the platform to move a predetermined distance on a supporting surface. Pneumatic control means are associated with the first and second pneumatic cylinder means so that the swinging of the arm is synchronized as desired with the movement of the platform.
