Abstract

The invention relates to a construction machine having an upper carriage, an undercarriage which has a running gear and on which the upper carriage is rotatably supported about an upright axis, and a feed arm for at least one energy line, with which energy can be supplied from the outside to the construction machine, wherein the feed arm is adjustably supported on the upper carriage. In accordance with the invention at least one drive means for actively adjusting the feed arm relative to the upper carriage is provided.

First claim

The invention claimed is:

1 . A construction machine having
an upper carriage, an undercarriage which has a running gear and on which the upper carriage is rotatably supported about an upright axis, and a feed arm for at least one energy line, with which energy can be supplied from the outside to the construction machine, the feed arm being adjustably supported on the upper carriage, drive means for actively adjusting the feed arm relative to the upper carriage, and control means for controlling the drive means to adjust the feed arm to reduce a stress on the energy line.

2 . The construction machine according to claim 1 ,
wherein the control means is for detecting a position of the upper carriage relative to the undercarriage, and the control means is designed to control the drive means depending on a detected change of position of the upper carriage.

3 . The construction machine according to claim 2 ,
wherein the control means is designed to control the drive means such that the feed arm is at a standstill or largely at a standstill relative to the energy line fed from the outside.

4 . The construction machine according to claim 1 ,
wherein the feed arm is pivotably supported about a pivot axis on an upper side of the upper carriage.

5 . The construction machine according to claim 4 ,
wherein the pivot axis of the feed arm is directed parallel to the upright axis of the upper carriage and/or arranged in the region of the upright axis.

6 . The construction machine according to claim 5 ,
wherein the pivot axis of the feed arm is arranged coaxially to the upright axis of the upper carriage.

7 . The construction machine according to claim 1 ,
wherein the feed arm is directed radially to the upright axis of the upper carriage and designed with a length, wherein in every pivot position the feed arm projects laterally over the upper carriage.

8 . The construction machine according to claim 1 ,
wherein a length of the feed arm is adjustable, in particular depending on a pivot position of the feed arm relative to the upper carriage.

9 . The construction machine according to claim 1 ,
wherein the feed arm comprises at least two arm members which are adjustable with respect to each other.

10 . The construction machine according to claim 9 ,
wherein the at least two arm members are pivotably connected to each other via at least one joint.

11 . The construction machine according to claim 1 ,
wherein the feed arm is height-adjustable in the axial direction of the pivot axis.

12 . The construction machine according to claim 1 ,
wherein a warning means is provided, by which a position of the feed arm relative to the upper carriage and/or to further components of the construction machine and/or to obstacles in the surrounding area can be detected and a possible collision with the feed arm can be established.

13 . The construction machine according to claim 12 ,
wherein one or several sensor means, in particular a camera unit, for detecting obstacles are arranged.

14 . The construction machine according to claim 1 ,
wherein along the feed arm the energy line is guided with a variable length.

15 . The construction machine according to claim 1 wherein a line drum, a cable track, and/or a line tensioning means for the energy line is arranged on the upper carriage.
