<p>An improved high-capacity apparatus (10) for rapidly pressure treating a large surface area, such as the hull of a cargo ship or a large storage tank, using high-pressure spray. The apparatus (10) conforms to the surface to be treated and provides the treating power of multiple rotating nozzles (18). The apparatus (10) preferably comprises a framework (174) comprised of one or more frame members; at least one rotary spray unit (12) flexibly associated with each frame member, each rotary spray unit (12) comprising at least one rotary spray arm (16) having at least one nozzle (18) directed away from the framework, a high pressure surface treatment medium supply conduit (14A), a rotary union (14) having an axis of rotation and connecting the high pressure medium supply conduit (14A) with the rotary spray arm (16); enclosure means for individually and/or collectively enclosing the rotary spray units against the surface being treated.</p> |
