Abstract
A carrier vehicle is solidly connected to a stationary support frame (2) which carries, by pivot joints or of a ball joint (3), a movable support frame (1) obliged to pivot only about a transverse axis relative to the direction of the travel of the vehicle and, optionally, a vertical axis. The movable support frame (1) carries a treatment boom of a suspension, for example of the swinging or rocker link type, acting in a transverse plane. The center of gravity of the assembly that includes the movable support frame and the boom is maintained on a vertical line passing through the pivot joint or the ball joint (3) or in a plane passing through the transverse axis and containing the resultant of the gravitational and inertial forces which are exerted on this assembly.
