Abstract

An exchangeable sweeping brush device for a carrier vehicle is provided. The device has at least one sweeping brush which is rotationally drivable about an almost vertically oriented axis of rotation of the brush and is held on a supporting frame, the supporting frame being detachably connectable to a supporting fork of the carrier vehicle, which is pivotable about a first horizontal pivot axis oriented transversely to the longitudinal axis of the vehicle. The supporting frame comprises a first supporting assembly on which the at least one sweeping brush is rotatably mounted, and a second supporting assembly which is detachably connectable to the supporting fork, the first supporting assembly being connected to the second supporting assembly for pivotal movement about a second horizontal pivot axis and being detachably connectable to the carrier vehicle by at least one tension member. A sweeper having such a sweeping brush device is also proposed.
