Abstract

The invention relates to a construction machine (1) with a machine frame (2), a driver cab (6) with a right and a left door-window unit (12) when viewed in a traveling direction (A) of the construction machine (1), wherein the door-window units (12) are adjustable between a closed and an open position, and with a drive engine (13) and front and rear traveling devices (4, 5). Essentially, the door-window units (12) can be opened in an opposite manner, in particular depending on the side of the machine frame (2) on which the front and rear traveling devices (4, 5) respectively sit flush with the machine frame (2). The invention is particularly relevant for ground compaction machines, in particular rubber-tired rollers. The invention further relates to a method for operating a construction machine (1) and a method for manufacturing a construction machine (1).

First claim

What is claimed is:

1. A compaction machine, comprising:
a machine frame;
a driver cabin having a right and a left door-window unit when viewed in a traveling direction of the compaction machine, said door-window units being adjustable between a closed and an open position;
a drive engine; and
front and rear traveling devices;
wherein the door-window unit of the right side and the door-window unit of the left side are adjustable from the closed position to the open position at least partially in opposite directions (X) with respect to one another when viewed in the traveling direction.

2. The compaction machine according to claim 1 , wherein the driver cabin comprises vehicle pillars on right and left sides of the driver cabin, and that the door-window units are each arranged at a respective vehicle pillar, the door-window unit on one side being arranged at a front vehicle pillar when viewed in the traveling direction and the door-window unit on the other side being arranged at a rear vehicle pillar when viewed in the traveling direction.

3. The compaction machine according to claim 1 , wherein the front and rear traveling devices are arranged with an offset transverse to the traveling direction and towards opposite sides and each include a zero side (NR, NL) with one face side sitting flush with one side of the machine frame, and wherein the door-window units are each arranged such that the door-window units can be opened away from the traveling device located on a respective zero side (NR, NL).

4. The compaction machine according to claim 1 , wherein the door-window units are mounted at a frame of the driver cabin and/or a vehicle pillar via a door hinge and can swivel between the closed position and the open position.

5. The compaction machine according to claim 1 , wherein the door-window units are configured essentially symmetrical with respect to an outer contour of the door-window units.

6. The compaction machine according to claim 1 , wherein the door-window units of the right and the left side of the compaction machine are identical in construction.

7. The compaction machine according to claim 1 , wherein the door-window units of the right and the left side are arranged at the compaction machine in a centrosymmetrical manner with respect to a horizontal reference plane.

8. The compaction machine according to claim 1 , wherein the door-window units each comprise a door element and a window element.

9. The compaction machine according to claim 8 , wherein the door element and the window element of a door-window unit comprise at least one of the following features:
the window element can be opened independently of the door element;
the window element and the door element open in a same direction;
the window element and the door element are arranged at the driver cabin and/or the vehicle pillar such that the window element and the door element are each adjustable about a shared swivel axis (D) on one side.

10. The compaction machine according to claim 1 , wherein the compaction machine is a rubber-tired roller.

11. A method for operating a compaction machine, according to claim 1 , wherein the compaction machine includes a driver cabin with, when viewed in a traveling direction of the compaction a right and a left door-window unit which are each adjustable between a closed and an open position, and front and rear traveling devices which are arranged with an offset transverse to the traveling direction and each include a zero side (NR, NL) towards opposite sides and, with one face side sitting flush with one side of the machine frame on the respective zero side (NR, NL),
wherein the respective door-window unit located on the respective zero side (NR, NL) is adjusted to the open position against the current traveling direction both in the case of forward as well as backward travels of the compaction machine.

12. A method for manufacturing a compaction machine according to claim 1 , wherein an attachment of door-window units to a driver cabin of the compaction machine is performed such that the door-window unit on one side opens in a traveling direction of the compaction machine and the door-window unit on the other side opens against this traveling direction of the compaction machine.
