Patent

CA 2145987

The invention relates to a brush head for large machines for cleaning large objects like aircraft. The brush head (18) has a brush roller (58) motor-driven in a predetermined direction of rotation (130), bearing a crown (66) of flexible, centrifugally born bristles (104) and acting with the bristles (104) against a surface to be cleaned. In order to prevent damage to the surface to be cleaned during inevitable breakdowns, the invention proposes at least one contact sensor (88), preferably rotating with the brush roller (58) and recessed inside the crown of bristles (66) to trigger an emergency stop acting on the drive system of the brush head (18).
