ABSTRACT:
An improved apparatus and method for cleaning and stripping residue, contaminants, debris. etc. from all of the interior spaces in a railway tank car and the like. The present invention may be conveniently lowered into a tank car through its manway and, after quick assembly thereof, pneumatically configured to accommodate the physical dimensions of the tank car, and then be preset for automatic cleaning and/or stripping operation. A means is provided which inherently coordinates and synchronizes the cleaning and stripping of virtually every internal surface contained in a tank car. The preferred embodiment comprises a X-frame assembly having a pair of corresponding X-members which are attached by an axle disposed therebetween. Pivotally attached to this X-fame assembly is a swivel support assembly which receives a K-frame assembly comprising a plurality of arm means, linkage means and spray means spraying all of the interior surfaces of a tank car.
