INSTALLATION FOR TREATING LARGE VERTICAL SURFACES, PARTICULARLY OUTER SURFACES OF VERTICAL CYLINDRICAL CONTAINERS

摘要

The installation disclosed in the present invention is essentially intended to the cleaning and anticorrosive treatment of large vertical surfaces, particularly outer surfaces of vertical cylindrical containers, and comprises a mast provided with wheels and carrying a moving structure which may be vertically displaced by a drive. The movable structure (5) comprises a curved path of which the curvature corresponds to that of the surface to be treated, and a movable support driven in both direction by a drive (7) and carrying the dispersion device (9) corresponding to a given work phase and projecting the treating agent.
