Abstract

A height-adjustable operating platform of a compact paver comprising a machine frame, a drive motor, travel units, a receiving container at the front in relation to the paving direction for receiving paving material, a longitudinal conveying device with which the paving material can be conveyed from the receiving container in a rearward direction in relation to the paving direction, a transverse distribution device that is height-adjustable in relation to the machine frame and with which the paving material can be distributed on the ground surface transversally to the paving direction, a paving screed that is height-adjustable in relation to the machine frame for compacting and smoothing the paving material distributed on the ground surface behind the transverse distribution device in the paving direction, an operating platform mounted on the machine frame and arranged behind the receiving container in the paving direction and a method for operating a compact paver.

First claim

What is claimed is:

1. A compact paver, comprising:
a machine frame;
a drive motor;
travel units;
a receiving container arranged at the front in the paving direction for receiving paving material;
a longitudinal conveying device, with which the paving material is conveyable from the receiving container rearward in relation to the paving direction;
a transverse distribution unit that is height-adjustable in relation to the machine frame and with which the paving material is distributable transversely to the paving direction on the ground surface;
a paving screed that is height-adjustable in relation to the machine frame for compacting and smoothing the paving material distributed laterally on the ground surface behind the transverse distribution device in the paving direction;
an operating platform mounted on the machine frame and arranged behind the receiving container in the paving direction, wherein the operating platform is height-adjustable in relation to the machine frame in such a way that the height adjustment of the operating platform is coupled to a height adjustment of the paving screed and/or to a height adjustment of the transverse distribution device; and
wherein, for the height adjustment of the operating platform, a lifting tab, configured to contact a tab counterpart on the operating platform, is provided on each of the paving screed and the transverse distribution device, respectively.

2. The compact paver according to claim 1 , wherein the height adjustment of the operating platform is driven indirectly in such a way that a drive device for the height adjustment of the paving screed and/or the transverse distribution device triggers the height adjustment of the operating platform.

3. The compact paver according to claim 1 , wherein the operating platform is mounted directly on the machine frame in a height-adjustable manner by a linear guiding mechanism with an essentially vertical displacement path.

4. The compact paver according to claim 1 , wherein the paving screed and the transverse distribution device are configured for height adjustment of the operating platform alternatively.

5. The compact paver according to claim 1 , wherein a tab counterpart for the paving screed and a tab counterpart for the transverse distribution device are arranged on the operating platform in an offset manner such that the tab counterpart for the paving screed is arranged behind the tab counterpart for the transverse distribution device in the paving direction.

6. The compact paver according to claim 1 , wherein a lowering stop is provided on the machine frame which determines the maximum lowered state of the transverse distribution device and/or of the operating platform and against which the transverse distribution device and/or the operating platform strikes when the maximum lowered position in relation to the machine frame is reached.

7. The compact paver according to claim 1 , wherein the height adjustment of the operating platform is coupled to both the height adjustment of the paving screed and the height adjustment of the transverse distribution device, wherein the coupling is configured in such a way that the paving screed or the transverse distribution device can respectively decouple each other from their respective connections with the operating platform when raised.

8. The compact paver according to claim 1 , wherein the height adjustment of the transverse distribution device comprises a rail guide connected to the machine frame.

9. The compact paver according to claim 1 , wherein a sliding roller is provided on the paving screed for contacting the underside of the operating platform.

10. The compact paver according to claim 1 , wherein the operating platform comprises two operating steps arranged in an offset manner in relation to one another in the paving direction, and
wherein the operating platform comprises at least one of the following features
a front operating step in the paving direction is positioned higher in the vertical direction than a rear operating step in the paving direction;
the front operating step in the paving direction is positioned above the paving screed;
the operating steps form an overall rigid structure by a support frame; and
the front and rear operating steps are arranged one directly behind the other in the working direction and/or form an overall rigid structure by a support frame.

11. The compact paver according to claim 1 , wherein the operating platform has a multi-functional seat and/or a back support comprising at least one of the following features
the seat and/or the back support is adjustable by insertion between two operating positions within the operating platform, a first position associated with a first operating step and a second position associated with a second operating step; and
the seat is movable between a sitting operating position and a standing operating position and is pivotable about a horizontal axis.

12. The compact paver according to claim 1 , wherein an adjustable operating console is arranged on the operating platform, comprising at least one of the following features
the operating console is mounted on a supporting frame of the operating platform in an adjustable manner; and
the operating console is adjustable between an upper operating position, in which the operating console is positioned for operation by an operator on the front operating step, and a lower operating position, in which the operating console is positioned for operation by an operator on the rear operating step.

13. A method for operating a compact paver, comprising:
obtaining the compact paver, wherein the compact paver comprises
a machine frame;
a drive motor;
travel units;
a receiving container arranged at the front in the paving direction for receiving paving material;
a longitudinal conveying device, with which the paving material is conveyable from the receiving container rearward in relation to the paving direction;
a transverse distribution unit that is height-adjustable in relation to the machine frame and with which the paving material is distributable transversely to the paving direction on the ground surface;
a paving screed that is height-adjustable in relation to the machine frame for compacting and smoothing the paving material distributed laterally on the ground surface behind the transverse distribution device in the paving direction; and
an operating platform mounted on the machine frame and arranged behind the receiving container in the paving direction, wherein the operating platform is height-adjustable in relation to the machine frame in such a way that the height adjustment of the operating platform is coupled to a height adjustment of the paving screed and/or to a height adjustment of the transverse distribution device;

lowering or raising the transverse distribution device and, in so doing, carrying along the operating platform, and/or lowering or raising the paving screed and, in so doing, carrying along the operating platform; and
wherein the operating platform is removed from the coupling of the operating platform with the paving screed when the transverse distribution device is raised or in that the operating platform is removed from the coupling of the operating platform with the transverse distribution device when the paving screed is raised.

14. The method according to claim 13 , wherein the operating platform is guided in a linear guiding mechanism, on the machine frame during a height adjustment.

15. A compact paver, comprising:
a machine frame;
a drive motor;
travel units;
a receiving container arranged
