Abstract
Abstract A mechanical sweeper attached to a carrier vehicle comprises a sweeping assembly (2) which is attached laterally to the frame of a carrier vehicle (1) between the front and rear wheels. The sweeping assembly is attached as one unit to a carrier frame (26) which is movably connected to the vehicle in order to shift the sweeping assembly (2) into a position outside the lateral profile outline of the vehicle (1). In the case of a mechanical sweeper having an interchangeable body (6), which, on a body frame (8), includes devices for picking up and storing the dirt and is arranged as a whole above the rear wheels (4) of the carrier vehicle (1), the carrier frame (26) is fastened to the body frame (8) of the interchangeable body (6) so that it can be pulled out laterally. The lateral pulling out movement is facilitated by a supporting device which comprises a leg (11) fastened to the carrier frame (26), this leg being supported on the ground (9) by means of a support roller (12), on the side of the sweeping assembly (2) opposite the vehicle.

Claim 2
Dependent Claim
84 words
Mechanical sweeper comprising a sweeping assembly arranged on a carrier vehicle having front and rear wheels, said sweeping assembly being attached as a single unit to and hence movable with a carrier frame, guide means for movably attaching said carrier frame to the vehicle, said carrier frame being movably attached to the carrier vehicle by said guide means for shifting the sweeping assembly into an inoperative position outside the lateral profile outline of the vehicle to facilitate servicing or removal of said sweeping assembly.
Claim 3
Dependent Claim
151 words
Mechanical sweeper comprising a sweeping assembly arranged on a carrier vehicle having front and rear wheels, said sweeping assembly, in the operative position, being arranged on the side of the carrier vehicle between the front and rear wheel, said sweeper further comprising an interchangeable body on a body frame arranged above the rear wheels of the carrier vehicle, said body including devices for picking up and storing dirt, characterized in that the sweeping assembly is attached as a single unit to and hence movable with a carrier frame, guide means for movably attaching said carrier frame to said body frame, said carrier frame, together with the sweeping assembly, being movably fastened to the body frame by said guide means in such a manner that the sweeping assembly can be moved into an inoperative position outside the lateral profile outline of the vehicle to facilitate servicing or removal of said sweeping assembly.
Claim 4
Dependent Claim
151 words
Mechanical sweeper comprising a sweeping assembly arranged on a carrier vehicle having front and rear wheels, said sweeping assembly, in the operative position, being arranged on the side of the carrier vehicle between the front and rear wheel, said sweeper further comprising an interchangeable body on a body frame arranged above the rear wheels of the carrier vehicle, said body including devices for picking up and storing dirt, characterized in that the sweeping assembly is attached as a single unit to and hence movable with a carrier frame, guide means for movably attaching said carrier frame to said body frame, said carrier frame, together with the sweeping assembly, being movably fastened to the body frame by said guide means in such a manner that the sweeping assembly can be moved into an inoperative position outside the lateral profile outline of the vehicle to facilitate servicing or removal of said sweeping assembly.
Claim 5
Dependent Claim
39 words
Mechanical sweeper according to claim 1 or 2, characterized in that the carrier frame, together with the sweeping assembly can be moved by means of a supporting device into a position outside the lateral profile outline of the vehicle.
