The metallic surfaces (17-47) will be cleaned either with water blast or with sand/grit blast, or with both of them. A crane-carrying vehicle will be provided (1) (35-43-40-51) with retracting arms (2) and one cabin (6) on the extremity of the arms where is fitted, at the lower, front, starboard and portside, a steel-made bar (7) the shape of which will correspond to the surface being cleaned up. The bar will be provided with a big number of guns (8) (waterblast) or of nozzles-injectors (8) (sand/grit blast-painting) of varying bores, as the case may be. Also, it will be possible to be fitted, as an alternative, in the place of the guns or of the nozzles-injectors, turning discs (8.20-21-22-23-24-25-26-27-28) which will be, in turn, fitted with nozzles or guns, as the case may be. The entire system will hydraulically, robot-electrically, mechanically or hydropneumatically clean up very quickly big areas (17-47). There will also be provided a system or a compressed air system (water shot) (11) or a compressed air (11) and mortar suction system (sand/grit blast), water (waterblast) (12-13-14-15-16. The sand/grit blasting bottle (29) will be with less hoses (1) at the outlet 54 of 1,5'' up to 3'' in diameter. The painting of the paint pump (30) will be of higher output and discharge rate. The drums of paint (32) will lend easier the carriage of paints. There will also be provided a plate (31) which will accept, through an automatic operation, from 1 to 10 cables. The cranes (35-51) will be provided with a first aid box, a stretcher, fire protection and elevator (44).
