ABSTRACT:
A mobile, abrasive, surface treating device in which an impeller fan is disposed within a circular housing to direct a stream of abrasive material from a hopper against the treated surface in a blasting fashion. A movable frame assembly supports the open face of the housing in abutment with the treated surface, and a resilient element on the housing prevents dispersal of the abrasive material. The spent abrasive material is recovered and recycled by a continuous bucket conveyor system. Fluid motors cooperate with a system of winches and cables to control movement of the device over the treated surface.
