Abstract

A loading apparatus, in particular for conveying freight over a road surface and loading it into a transporting vehicle and unloading it therefrom, comprises a basic structure, a loading structure, with a freight holder, and a double-action lifting device between the basic structure and the loading structure. The loading structure here comprises a lifting frame, on which the lifting device acts, and a freight carrier, which is mounted on the lifting frame, via a pull-out guide with a pull-out direction oriented transversely to the lifting direction, and has the freight holder. An undercarriage serving for advancing the loading apparatus over the road surface is part of the freight carrier.

Claims

1. A loading apparatus (1), especially for conveying freight (F) over a road surface (V) and loading it into or unloading it from a transport vehicle, comprising:

a base structure (2),

a loading structure (3) with a freight holder (10) and

a double-acting lifting device (4) between the base structure (2) and the loading structure (3),

wherein the loading structure (3) comprises a lifting frame (11), on which the lifting device (4) acts, and a freight carrier (12), which is mounted on the lifting frame (11) via a pull-out guide (13) with a pull-out direction (A) oriented transversely relative to the lifting direction (B) and is equipped with the freight holder (10),

wherein the lifting device comprises a scissor lift, and

wherein the bearing of the scissor lift located in the pull-out direction on the base structure is a fixed bearing and the bearing of the scissor lift located opposite the pull-out direction is a floating bearing such that a crossing point of arms of the scissor lift move towards the pull-out direction when the loading structure is lifted by the scissor lift, and

wherein an undercarriage (43) serving for travel of the loading apparatus (1) over the road surface (V) is part of the freight carrier (12).

2. The loading apparatus of claim 1, wherein the undercarriage (43) comprises wheels (29, 30), preferably four wheels (29, 30), which particularly preferably are disposed on the side edges of the freight carrier (12).

3. The loading apparatus of claim 2, wherein that at least some of the wheels (29, 30) are steerable.

4. The loading apparatus of claim 2, wherein at least some of the wheels (29, 30) are equipped with brakes, which preferably can be remotely actuated.

5. The loading apparatus of claim 1, wherein the base structure (2) does not extend laterally beyond the width of the undercarriage (43), especially the track width of the wheels (29, 30).

6. The loading apparatus of claim 5, wherein the width of the base structure (2) on its side opposite the pull-out direction (A) corresponds substantially to the width of the undercarriage (43), especially the track width of the wheels (30).

7. The loading apparatus of claim 1, wherein support feet (8) are disposed on the base structure (2).

8. The loading apparatus of claim 7, wherein a load sensor is assigned to at least one of the support feet (8).

9. The loading apparatus of claim 7, wherein at least one of the support feet (8) can be laterally extended, pulled out or folded out.

10. The loading apparatus of claim 1, wherein no wheels are disposed on the base structure (2).

11. The loading apparatus of claim 1, wherein an extending drive acting between the lifting frame (11) and the freight carrier (12) is provided.

12. The loading apparatus of claim 11, wherein a controller, which controls the extension movement with due consideration of safety-relevant parameters, acts on the extending drive.

13. The loading apparatus of claim 1, wherein at least one sensor for detection of the position of the freight carrier (12) relative to a loading surface is disposed on the freight carrier (12), preferably in the region of the front wheels (29).

14. The loading apparatus of claim 1, wherein at least one of the arms (19, 20) of the scissor lift is cranked and/or a drive element (32) acts on one of the arms (19) at a position offset from the pivot point (18).

15. The loading apparatus of claim 1, wherein the lifting device (4) comprises an electrical or an electrohydraulic drive unit.

16. The loading apparatus of claim 15, wherein an electrical storage unit of the drive unit is disposed on the lifting frame (11), preferably on its front side pointing in pull-out direction (A).

17. The loading apparatus of claim 15, wherein an electrical storage unit of the drive unit is designed as an interchangeable battery.

18. The loading apparatus of claim 15, wherein an electrical storage unit of the drive unit is provided with a charging terminal, which can be connected to the electrical system of a transport vehicle designed as a motor vehicle.

19. The loading apparatus of claim 1, wherein at least one auxiliary roller is disposed at variable positions on the front side of the freight carrier (12).

20. The loading apparatus of claim 1, wherein the freight carrier (12) can be interlocked relative to the lifting frame (11).

21. The loading apparatus of claim 1, wherein the lifting device (4) can be locked in a partly raised position of the loading structure (3).

22. The loading apparatus of claim 1, wherein a handle (35), which is equipped with operator controls, is disposed on the lifting frame (11) at its end opposite the pull-out direction (A).

23. The loading apparatus of claim 22, wherein the handle (35) is attached to the lifting frame (11) or to the base structure (2) by pivoting or retracting means.

24. The loading apparatus of claim 22, wherein the handle (35) is equipped with an extensible drawbar (37), wherein the extension direction of the drawbar (37) is oriented obliquely relative to the lifting direction (B), preferably by being inclined slightly in rearward direction.

25. The loading apparatus of claim 24, wherein the length of the drawbar (37) can be varied by a length-adjusting drive, wherein the length-adjusting drive preferably can be inversely coupled phase-wise with the lifting drive.

26. The loading apparatus of claim 1, wherein the freight carrier (12) is provided with a loading platform (9), at least one bulk-goods holder or a special retainer, especially as part of an exchangeable attachment.

27. The loading apparatus of claim 1, wherein the freight carrier (12) is provided with suitable retainers for attachment of fastening and/or securing means for the freight.

28. The loading apparatus of claim 1, wherein the pull-out guide comprises three slidable members including an intermediate rail.
