ROAD SWEEPING MACHINE

La présente invention se rapporte à une balayeuse de voirie. Une balayeuse est présentée dans laquelle le mouvement des bras porte-balai (3) dans un plan vertical est actionné par un ensemble de quatre profilés, disposés en deux paires qui chacune forment un parallélogramme déformable, et dans laquelle la déformation du parallélogramme est actionnée par un vérin (25) et le poids propre du bras de balayage. Le vérin est configuré pour rester en dessous des profilés supérieurs (11) des deux paires, quand le bras porte-balai est levé au maximum. The present invention relates to street sweeper. According to a first aspect of the invention, different mechanisms are disclosed for controlling the movement of the brush-holder arms in a horizontal plane, while also damping side and front impacts. According to a second aspect, a sweeper is disclosed, in which the movement of the brush-holder arms (3) in a vertical plane is imparted by a set of four profile members, arranged in two pairs which each forms a deformable parallelogram, wherein the deformation of the parallelogram is actuated by a jack (25) and the own weight of the sweeping arm. The jack is configured to remain below the upper profile members (11) of the two pairs when the brush-holder arm is raised to its maximum height. According to a third aspect, the suction turbine (103) is arranged in such a way that load losses are reduced during the operation of the sweeper.
