ABSTRACT:
A ground-engaging travelling structure supporting a member which is pivotally mounted on the structure for swinging movement about a fore-and-aft axis of the structure and including a device to maintain the member in a substantially constant position with respect to the structure and the ground. The member may be an upright pipe supplying an irrigation boom with water and the device may be actuated by a pendulum and so be responsive to deviation of the supply pipe from the upright position and operable to operate a fluid actuator to restore the supply pipe to its upright position. The actuator may be connected in a circuit including pressure-relief valves operable to limit the end loading which is permitted to be exerted on the boom by the supply pipe.
