US 10,094,079 B2 · Positioning arrangement for fitting an interchangeable milling assembly of a road-building machine

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.

Dependent claims

A method of fitting a milling assembly below a machine chassis of a road building machine, the machine chassis carried on wheels or track-laying units, using a positioning arrangement, the method comprising:

(a) driving the positioning arrangement, with the milling assembly resting on the positioning arrangement and when in a lowered position, under the machine chassis of the road building machine such that a longitudinal direction of a handling chassis of the positioning arrangement extends transversely to a longitudinal direction of the road building machine;
(b) raising the positioning arrangement from the lowered position to a raised position;
(c) fitting the milling assembly to the road building machine;
and
(d) lowering the positioning arrangement from the raised position and driving the positioning arrangement away without the milling assembly resting on the positioning arrangement.

A method of removing a milling assembly from below a machine chassis of a road building machine, the machine chassis carried on wheels or track-laying units, using a positioning arrangement, the method comprising:

(a) driving the positioning arrangement, without the milling assembly resting on the positioning arrangement and when in a lowered position, under the machine chassis of the road building machine such that a longitudinal direction of a handling chassis of the positioning arrangement extends transversely to a longitudinal direction of the road building machine;
(b) raising the positioning arrangement from the lowered position to a raised position;
(c) removing the milling assembly from the road milling machine;
and
(d) lowering the positioning arrangement from the raised position and driving the positioning arrangement away with the milling assembly resting on the positioning arrangement.
