PCT No. PCT/EP94/02556 Sec. 371 Date Feb. 28, 1996 Sec. 102(e) Date Feb. 28, 1996 PCT Filed Jul. 30, 1994 PCT Pub. No. WO95/06586 PCT Pub. Date Mar. 9, 1995The invention relates to a device for handling a brush head for cleaning the surfaces of large objects like aircraft, ships or buildings. The handling device has a multi-joint assembly carrying a brush head (18) on the end extension (14) of an angled mast (13) having, extending from the end extension (14), three motor-driven rotary units (60, 62, 64) arranged one behind the other and having alternately perpendicular axes (60', 62', 64') and a motor-driven telescopic linear unit (66') secured to the last rotary unit (64) and aligned with its axis of rotation (64'). In order to ensure that the brush roller is always perpendicular to the surface to be cleaned along its entire travel, even at points which are difficult of access, the invention proposes that axes (60', 66') of the rotary unit (60) on the end extension side and of the linear unit (66) be arranged in laterally staggered, mutually parallel planes. |
