Abstract

In an automotive construction machine, with a machine frame (4) with preferably vertically arranged lateral outer walls (5), a milling drum (6) mounted in the machine frame (4) for working a ground surface or traffic surface (8), and with an operator's platform (10), it is provided that the operator's platform (10) is moveable on the machine frame (4) transversely to the direction of travel, and is moveable outwards beyond the lateral outer walls (5) of the machine frame (4), that the machine frame (4) is provided with a guide (18) for the operator's platform (10) acting transversely to the direction of travel, and that the guide (18) projects laterally either not at all or just slightly beyond the outer walls (5).

First claim

What is claimed is:

1. A front loading road milling machine, comprising:
a machine frame having a frame front end and a frame rear end with reference to a direction of travel, the machine frame including essentially vertically arranged lateral outer walls, the machine frame having a frame width defined between the outer walls;
a pair of front crawler track units and a pair of rear crawler track units for supporting the machine frame from a ground surface;
a milling drum supported from the machine frame between the front and rear crawler track units for working the ground surface, the milling drum extending transversely to the direction of travel of the machine frame and having a drum end in close proximity to one of the lateral outer walls to define a zero side of the milling machine so that milling close to obstacles is possible on the zero side of the milling machine;
a belt drive connected to the milling drum and arranged on the other lateral outer wall of the machine frame opposite from the zero side;
a first transport conveyor arranged in front of the milling drum for receiving milled material from the milling drum;
a second transport conveyor extending forward from the frame front end for receiving the milled material from the first transport conveyor and conveying milled material forward onto a transport vehicle located forward of the road milling machine, the second transport conveyor having a second transport conveyor front discharge end and a second transport conveyor rear end, the second transport conveyor rear end being pivotally connected to the frame front end so that the second transport conveyor is pivotal about both a horizontal axis and a vertical axis relative to the frame, the second transport conveyor including a structural framework, the second transport conveyor extending forward of the machine frame by a distance substantially greater than the frame width;
a plurality of lifting columns connected between the machine frame and the crawler track units for adjusting a milling depth of the milling drum by adjusting a height of the machine frame above the ground surface;
an operator's platform located on the machine frame;
a video camera supported from the structural framework of the second transport conveyor nearer to the second transport conveyor front discharge end than to the second transport conveyor rear end, the video camera facing forward and downward to monitor the discharge of material from the second transport conveyor onto the transport vehicle located forward of the road milling machine and
the operator's platform further including a seat having a seat surface adjustable in height such that an eye level of the operator when sitting essentially corresponds to an eye level of the operator when standing within the operator's platform.

2. The road milling machine of claim 1 , wherein the video camera is located adjacent an underside of the structural framework of the second transport conveyor.

3. The road milling machine of claim 1 , wherein the video camera is located at the second transport conveyor front discharge end.

4. The road milling machine of claim 1 , wherein the video camera is located adjacent an underside of the second transport conveyor adjacent the second transport conveyor front discharge end.

5. The road milling machine of claim 1 , wherein the operator's platform is located between the front and rear crawler track units.

6. The road milling machine of claim 5 , wherein the operator's platform is located above the milling drum.

7. The road milling machine of claim 1 , wherein an operating and indicating panel is integrated into the operator's platform.

8. The road milling machine of claim 1 , wherein the operator's platform includes an operating and indicating panel.

9. The road milling machine of claim 8 , wherein the operating and indicating panel includes control, operating and indicating elements for a traveling mode, a milling mode, and for monitoring of the milling mode.

10. The road milling machine of claim 8 , wherein the operating and indicating panel includes an indicating element for monitoring of the milling mode.

11. The road milling machine of claim 1 , wherein the operator's platform includes an operating and indicating panel provided with a display for images from the video camera.

12. A front loading road milling machine, comprising:
a machine frame having a frame front end and a frame rear end with reference to a direction of travel, the machine frame including essentially vertically arranged lateral outer walls, the machine frame having a frame width defined between the outer walls;
a pair of front crawler track units and a pair of rear crawler track units for supporting the machine frame from a ground surface;
a milling drum supported from the machine frame between the front and rear crawler track units for working the ground surface, the milling drum extending transversely to the direction of travel of the machine frame and having a drum end in close proximity to one of the lateral outer walls to define a zero side of the milling machine so that milling close to obstacles is possible on the zero side of the milling machine;
a belt drive connected to the milling drum and arranged on the other lateral outer wall of the machine frame opposite from the zero side;
a first transport conveyor arranged in front of the milling drum for receiving milled material from the milling drum;
a second transport conveyor extending forward from the frame front end for receiving the milled material from the first transport conveyor and conveying the milled material forward onto a transport vehicle located forward of the road milling machine, the second transport conveyor having a second transport conveyor front discharge end and a second transport conveyor rear end, the second transport conveyor rear end being pivotally connected to the frame front end so that the second transport conveyor is pivotal about both a horizontal axis and a vertical axis relative to the frame, the second transport conveyor extending forward of the machine frame by a distance substantially greater than the frame width;
a plurality of lifting columns connected between the machine frame and the crawler track units for adjusting a milling depth of the milling drum by adjusting a height of the machine frame above the ground surface;
a video camera supported from the second transport conveyor nearer to the second transport conveyor front discharge end than to the second transport conveyor rear end, the video camera facing forward and downward to monitor the discharge of material from the second transport conveyor onto the transport vehicle located forward of the road milling machine;
an operator's platform located on the machine frame between the front and rear crawler track units and above the milling drum, the operator's platform including an operating and indicating panel and
the operator's platform further including a seat having a seat surface adjustable in height such that an eye level of the operator when sitting essentially corresponds to an eye level of the operator when standing within the operator's platform.
