Abstract (en)

[origin: EP1557121A2] The device (01) is designed as a carriage (04) attached to chains in order to be moved by a crane and is fitted with two transversally arranged drum-shaped cleaning brushes (02, 03). The brushes (02, 03) rotate in different directions and are supplied with a cleansing fluid from a nozzle bar (07) positioned between them. Most of the used fluid is caught by lateral panels (08) and collected in a tank (11) located at the bottom, serving also as a ballast element for an improved cleansing effect.
