Abstract

A track maintenance wagon (1) for picking up and/or laying a track panel (10), comprising a wagon frame (2) supported on on-track undercarriages (4), wherein two longitudinal beams (7) of the wagon frame (2) delimit a free opening and are transversely displaceable relative to one another, so that the free opening is changeable as to its width and, in a working position, has greater opening dimensions as a horizontal projection of the track panel (19), and wherein crane rails (8) are arranged on the longitudinal beams (7) for a gantry crane (11) mobile in the longitudinal direction (3) of the wagon. In this, buffers (13) are arranged at two free ends (12) of the longitudinal beams (7).

First claim

The invention claimed is:

1. A track maintenance wagon for picking up and/or laying a track panel, comprising
a wagon frame comprising two longitudinal beams;
a plurality of on-track undercarriages, wherein the wagon frame is supported on said on-track undercarriages, wherein said two longitudinal beams of the wagon frame delimit a free opening and are transversely displaceable relative to one another, so that the free opening is changeable as to its width and, in a working position, has greater opening dimensions as a horizontal projection of the track panel, and
a plurality of crane rails arranged at the longitudinal beams for a gantry crane mobile in the longitudinal direction of the wagon, wherein buffers are arranged at two free ends of the longitudinal beams.

2. The track maintenance wagon according to claim 1 , wherein draw gears are arranged at free ends of the longitudinal beams.

3. The track maintenance wagon according to claim 2 , wherein the draw gears are designed as rail bridges for the crane rails.

4. The track maintenance wagon according to claim 1 , wherein a displacement drive for a transverse displacement device is configured hydraulically.

5. The track maintenance wagon according to claim 1 , wherein a displacement drive for a transverse displacement device is configured electrically.

6. The track maintenance wagon according to claim 4 , wherein the displacement drive is configured as a spindle drive.
