ABSTRACT:
An abrasive cleaning apparatus comprising a truck adapted to run on the first surface to be cleaned, a first abrasive cleaner adapted to be pressed against the first surface and mounted on the truck by a first support assembly so as to be limitedly movable in the direction of a first axis substantially perpendicular to the first surface and and limitedly tiltable in every direction with respect to the first axis, and a second abrasive cleaner adapted to be pressed against the second surface to be cleaned and substantially perpendicular to the first surface and mounted on the truck by a second support assembly so as to be limitedly movable in the direction of a second axis substantially parallel to the first surface and to be limitedly tiltable in every direction with respect to the second axis. The apparatus is suited to use in ships and like structures including two members welded together at a right angle to each other for simultaneously cleaning the surfaces of the members by abrasion in the vicinity of the welded portion, especially when the surfaces have projections or undulations.
