Abstract

Rotary distribution header for use on mobile lifting and slewing cranes is used with low pressure air to operate the control systems. The inner body (21), on the chassis, has in its wall a series of deep holes (1a to 6a). Horizontal holes communicate with annular grooves (1b to 18b) in either wall of the body depending on the circuit. An outer sleeve (20), fixed to the rotating member (D), fits over the inner body, with takeoff points (1 to 18) from the corresponding annular grooves (1b to 18b). Seals (23) fit between all grooves. An inner core (22) is used for extra circuits. Mounted on a thrust race (25), it has annular grooves (22a), seals (24) and takeoff points (22b).
