Abstract
The invention relates to a positioning arrangement for fitting an interchangeable milling assembly of a preset working width below the vertically adjustable chassis of a road milling machine, which chassis is carried on track-laying units. A vehicle carried on a plurality of wheels has a unit for receiving the milling assembly. The positioning arrangement has a handling chassis which can be lengthened in the longitudinal direction and to which the wheels are fixed. In a lowered position, the positioning arrangement, with the milling assembly resting on it, can be driven below the chassis of the road milling machine. In a raised position, the milling assembly can be fitted to the road milling machine.
