Abstract

A trailer for a tugger train has a frame, which in the tow direction has a drawbar and a coupling, and which transverse to the tow direction has a laterally open receiving space for an inner wagon to be transported. A central web is arranged in the receiving space. The frame has connection means in each case for drawbar and coupling, and the frame has connection means for the central web for the releasable connection of the frame and connection means.

First claim

What is claimed is:

1. A trailer for a tugger train, comprising:
a frame, which in the tow direction has a drawbar and a coupling, and which transverse to the tow direction has a laterally open receiving space for an inner wagon to be transported; and
a central web arranged in the receiving space, wherein the frame has a first connector that connects the drawbar and the coupling and a second connector for the central web that releasably connects the frame and the central web,
wherein each of the first connector and the second connector is designed such that at least one of a form-locking, a force-fitting or a friction-fitting connection exists between the frame and the central web.

2. The trailer according to claim 1 , wherein the first connector forms a releasable connection for the drawbar and the coupling.

3. The trailer according to claim 1 , wherein the frame is substantially U-shaped.

4. The trailer according to claim 3 , wherein the central web is arranged centrally on the U-shaped frame or between coupling points of the drawbar and the coupling.

5. The trailer according to claim 1 , wherein the central web has an undercarriage.

6. The trailer according to claim 1 , wherein the frame and the central web are designed as two separate components that are connected together using a mounting flange.

7. The trailer according to claim 6 , wherein the frame at a bottom side thereof has the mounting flange for face-side attachment of the central web such that the receiving space is delimited at least on three sides by the frame, and downward by the central web.

8. The trailer according to claim 6 , wherein the central web has the mounting flange on a face-side for attaching to the frame, wherein the receiving space is delimited at least on three sides by the frame, and downward by the central web.

9. The trailer according to claim 1 , wherein a mounting flange is provided on the frame in a tow direction as the first connector for the drawbar and the coupling.

10. The trailer according to claim 1 , wherein the drawbar and the coupling each have, on frame-side ends thereof, a mounting flange as the first connector.

11. The trailer according to claim 1 , wherein the central web has a lifting apparatus.

12. A trailer for a tugger train, comprising:
a frame, which in the tow direction has a drawbar and a coupling, and which transverse to the tow direction has a laterally open receiving space for an inner wagon to be transported; and
a central web arranged in the receiving space, wherein the frame has a first connector that connects the drawbar and the coupling and a second connector for the central web that releasably connects the frame and the central web,
wherein, on each side of the central web, a ramp is provided upon which the inner wagon can be pushed.

13. The trailer according to claim 12 , wherein each of the first connector and the second connector is at least one of a screw connection or a bolt connection.

14. The trailer according to claim 12 , wherein each of the first connector and the second connector is designed such that at least one of a form-locking, a force-fitting or a friction-fitting connection exists between the frame and the central web.

15. A trailer for a tugger train, comprising:
a frame, which in the tow direction has a drawbar and a coupling, and which transverse to the tow direction has a laterally open receiving space for an inner wagon to be transported; and
a central web arranged in the receiving space, wherein the frame has a first connector that connects the drawbar and the coupling and a second connector for the central web that releasably connects the frame and the central web,
wherein the central web is one of a plurality of central webs releasably connected to the frame, wherein the frame is releasably connected to the trailer with any of the central webs.

16. The trailer according to claim 15 , wherein the frame is one of a plurality of frames for a set of trailers that differ in at least one of a frame strength thereof or a frame height thereof.

17. The trailer according to claim 15 , each central web of the plurality of central webs is implemented with or without rollers.

18. The trailer according to claim 15 , wherein the frame is one of a plurality of frames for a set of trailers, each frame differing in an undercarriage thereof.

19. The trailer according to claim 15 , wherein each of the first connector and the second connector is designed such that at least one of a form-locking, a force-fitting or a friction-fitting connection exists between the frame and the central web.
