Abstract

The invention relates to a road-building machine, comprising a drivable chassis (1) on which a driver'"'"'s cab (3) having a control panel (2) is provided. A canopy (5) that is fixed to the chassis by at least one support (6) is arranged above the driver'"'"'s cab, wherein at least one support (6) is adjustably arranged on the chassis (1) such that the canopy (5) can be lowered for a transport position and raised for a working position. For a working position with reduced set-up height, the lowered canopy (5) forms a free space (9) for an operator in the region of the control panel (2) of the driver'"'"'s cab (3), wherefore a canopy section covering the control panel (2) is designed such as to be movable relative to the chassis (1).

Claims

1. Road-building machine comprising a drivable chassis on which a driver'"'"'s cab having a control panel is provided, above which a canopy is set up which is fixed on the chassis by at least one support, wherein at least one support is set up adjustably on the chassis so that the canopy can be lowered for a transport position and set up for a working position, wherein for a working position with reduced set-up height the lowered canopy forms a free space for an operator in the region of the control panel of the driver'"'"'s cab, for which a canopy section covering the control panel is designed so as to be displaceable relative to the chassis.

2. Road-building machine as claimed in claim 1 wherein the canopy is arranged with supports on both sides for swivel movement on the chassis so that the canopy can be retracted for a transport position and folded out for a working position.

3. Road-building machine as claimed in claim 1 wherein the canopy can be lowered and set up by at least one telescopic support.

4. Road-building machine as claimed in claim 1 wherein the canopy section covering the control panel is a roof shell segment.

5. Road-building machine as claimed in claim 1 wherein the canopy can be shortened at the sides by displacing the covering canopy section.

6. Road-building machine as claimed in claim 1 wherein the canopy can be extended sideways by displacing the covering canopy section.

7. Road-building machine as claimed in claim 1 wherein the canopy has roof shell segments which are arranged so as to be displaceable on different guide levels.

8. Road-building machine as claimed in claim 1 wherein the active lateral roof lengths are aligned transversely to the driving direction (F).

9. Road-building machine as claimed in claim 1 wherein the canopy has an at least three-part roof shell whose roof shell segments are arranged so as to be displaceable one above the other.

10. Road-building machine as claimed in claim 1 wherein the canopy has a number of roof shell segments which can be pushed together like slats.

11. Road-building machine as claimed in claim 1 wherein at least one middle roof shell segment of the roof shell is arranged fixed, relative to which roof shell segments are arranged for lateral displacement.
