Abstract

A work vehicle for maintenance of an electrical catenary includes a vehicle frame supported on on-track undercarriages and a vehicle superstructure situated on the vehicle frame. A first grounding device is disposed at a first vehicle end relative to a longitudinal direction of the vehicle. A crane having a vertically and transversely adjustable work platform is disposed at an opposite, second vehicle end. A second grounding device is provided at the second vehicle end.

First claim

The invention claimed is:

1. A work vehicle for maintenance of an electrical catenary, the work vehicle comprising:
first and second mutually opposite vehicle ends defining a longitudinal direction of the vehicle;
on-track undercarriages;
a vehicle frame supported on said on-track undercarriages;
a vehicle superstructure disposed on said vehicle frame;
a first grounding device disposed at said first vehicle end;
a second grounding device disposed at said second vehicle end; and
a crane disposed at said second vehicle end, said crane having a vertically and transversely adjustable work platform.

2. The work vehicle according to claim 1 , wherein:
said crane has a vertical axis of rotation;
said second grounding device is constructed as a contact plate disposed on said crane; and
said contact plate has a vertical axis of symmetry disposed coaxially to said vertical axis of rotation of said crane.

3. The work vehicle according to claim 2 , wherein said contact plate is constructed as a circular sliding plate.

4. The work vehicle according to claim 2 , wherein:
said contact plate is constructed as a sliding strip extending transversely to said longitudinal direction of the vehicle; and
a drive rotates said sliding strip about said axis of symmetry relative to said crane.

5. The work vehicle according to claim 4 , which further comprises:
a gear unit connected to said drive;
said gear unit having at least two gearwheels;
one of said gearwheels forming an output side of said gear unit; and
said sliding strip being disposed at said gearwheel forming said output side of said gear unit.

6. The work vehicle according to claim 5 , which further comprises:
a drive for rotating said crane; and
a measuring and controlling unit connected to said drive for rotating said sliding strip and connected to said drive for rotating said crane.

7. The work vehicle according to claim 6 , wherein said second grounding device is connected to said measuring and controlling unit.

8. The work vehicle according to claim 6 , wherein said first grounding device is constructed as a vertically adjustable measuring bow connected to said measuring and controlling unit.

9. The work vehicle according to claim 1 , which further comprises at least one drive for vertical adjustment of said second grounding device.
