Abstract Positioning arrangement for fitting an interchangeable milling assembly of a road building machine such as a road milling machine, stabiliser or recycler The invention relates to a positioning arrangement for fitting an interchangeable milling assembly 21 of a preset working width below the vertically adjustable chassis 51 of a road milling machine 50, which chassis is carried on track-laying units 51A, 51B, 52A, 52B. The positioning arrangement according to the invention takes the form of a vehicle carried on a plurality of wheels which has a unit for receiving the milling assembly. The positioning arrangement has a handling chassis 1 which can be lengthened in the longitudinal direction and to which the wheels 9A, 9B, 10A, 1OB are fixed, to be adjustable vertically relative to the handling chassis, in such a way that the handling chassis can be moved from a position in which it is lowered to a position in which it is raised. In the lowered position, the positioning arrangement, with the milling assembly resting on it, can be driven below the chassis of the road milling machine. The positioning arrangement having been raised from the lowered position to the raised position, the milling assembly is at the height at which the said milling assembly can be fitted to the road milling machine.
