ABSTRACT:
A manually operated sweeping machine is disclosed having two circular brooms which are laterally arranged in the front area of a housing, rotate toward the inside and sweep over a sweeping lip. These circular brooms are each supported by means of a roller, the shaft holders of which are vertically adjustably held in the housing by means of supporting devices, for the adjustment of the distance between the sweeping lip and the floor. In the case of the state of the art, each supporting device is separately vertically adjustably. In addition, the shaft holders project through the housing into the supporting devices arranged on the exterior side of the housing. In the case of high axial loads on the shaft holders, these can therefore push through the supporting devices in the upward direction. According to the invention, a joint vertical-adjustment device is provided for the supporting devices.
