Abstract
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.
