Abstract

The device pertains to a carriage which may be separate or integrated with a mobile, powered loading vehicle to load or unload railroad track materials to or from a gondola and a method thereof.

Claims

1. A gondola carriage assembly for a gondola having at least two substantially parallel walls extending in a longitudinal direction, said two substantially parallel walls each having an upper edge, comprising:

a carriage defined by a frame, said frame formed of a plurality of structures forming a support for a track-driven loading machine having an end-less track for self-propulsion of said loading machine;

said carriage further comprising a plurality of axle assemblies rotatably connected to said frame;

said axle assemblies each having an axle and a gondola wheel at ends of said axle, said gondola wheels positioned to engage said upper edges of said gondola and allow movement of said carriage and said loading machine along said gondola;

said axle assemblies further having engagement portions to interface with tracks of said track-driven loading machine and to cause rotation of said gondola wheels along said upper edges of said gondola.

2. The gondola carriage assembly of claim 1 further comprising a connection element extending between said loading machine and said carriage, said connection element inhibiting movement of said loading machine relative to said carriage.

3. The gondola carriage assembly of claim 1, said frame comprising at least a first longitudinally extending beam and a second longitudinally extending beam.

4. The gondola carriage assembly of claim 3 further comprising at least two laterally extending beams extending between said longitudinally extending beams.

5. The gondola carriage assembly of claim 4, said at least one frame having at least three laterally extending beams.

6. The gondola carriage assembly of claim 4, each of said at least two laterally extending beams having one of said axle assemblies connected thereto.

7. The gondola carriage assembly of claim 6, said each of said plurality of axles having said gondola wheels at a first lateral end and a second lateral end.

8. The gondola carriage assembly of claim 1, said axle assemblies rotatably connected to said frame by a plurality of pillow block structures.

9. The gondola carriage assembly of claim 1, said carriage transmitting rotation of said tracks to rotation of said gondola wheels and driving said carriage along said gondola.

10. The gondola carriage assembly of claim 1 further comprising a leg axle pivotally connected to said carriage.

11. The gondola carriage assembly of claim 10, further comprising legs disposed at ends of said leg axle.

12. The gondola carriage assembly of claim 11, said legs being rotatable from an upper position allowing movement of said loading machine and carriage along said gondola to a lower position allowing movement of said gondola beneath said loading machine and said carriage.

13. The gondola carriage assembly of claim 12, said legs being extendable from a first length to a second length.

14. The gondola carriage assembly of claim 13, said legs having a plurality of nested segments.

15. A gondola carriage assembly for a gondola having a pair of longitudinally extending walls, said walls each having a forward end, a rearward end and an upper edge, comprising:

a carriage movably positionable on said gondola having;

a frame comprised of a plurality of beams;

a plurality of axle assemblies rotatably connected to said frame and extending substantially transverse to said longitudinally extending walls;

at least one of said plurality of axle assemblies having wheels capable of engaging said gondola;

ends of each of said plurality of axle assemblies engaging said pair of longitudinally extending walls;

a track-driven loading vehicle disposed on said carriage having;

at least one end-less track having an outer surface engaging a track engaging surface of said at least one of said plurality of axle assemblies having said wheels wherein rotation of said at least one end-less track causes rotation of at least a portion said wheels;

wherein said rotation of said at least a portion of said at least one of said plurality of axle assemblies causes movement of said carriage along said upper edges of said longitudinally extending walls.

16. The gondola carriage assembly of claim 15, said beams being a plurality of longitudinally extending frame members and at least two cross-braces.

17. The gondola carriage assembly of claim 15, each of said plurality of axle assemblies having an axle and a gondola wheel at each end of said axle.

18. The gondola carriage assembly of claim 15, said axle assemblies each having at least one pillow block connecting said axle assemblies to said frame cross-braces.

19. The gondola carriage assembly of claim 15, said axle assemblies further comprising an engagement portion which engages said end-less track of said loading vehicle.

20. The gondola carriage assembly of claim 15 further comprising a leg axle extending across said frame in a direction substantially transverse to said longitudinal extending axis.

21. The gondola carriage assembly of claim 20 further comprising rotatable and extendable legs connected to said leg axle.

22. The gondola carriage assembly of claim 21, said legs being rotated by a first actuator.

23. The gondola carriage assembly of claim 22, said legs being extendable by a second actuator.

24. The gondola carriage assembly of claim 15 further comprising a connecting element between said carriage and said loading vehicle.
