Abstract
A brush assembly is provided in a movable sweeper in which the sweeper includes a vehicle frame to which a rotatable cylindrical brush is connected. The sweeper comprises a turning equipment to turn a brush frame around the vertical axle. The turning equipment comprises a first hydraulic cylinder by means of which an articulated auxiliary bar is turned around its articulating joint. A second hydraulic cylinder is fixed to the auxiliary bar from one of its ends and the second hydraulic cylinder is fixed to the brush frame on its other end. The working positions of the brush are obtained by driving one of the hydraulic cylinders to its longest or correspondingly shortest position. A transporting position for the brush is obtained by driving the other one of the cylinders (first or second one) to its extreme position.
