Abstract

A goods transshipment apparatus having a mobile substructure with a superstructure mounted so as to be rotatable relative to said substructure and having a driver'"'"'s cab and engine compartment and a jib or jib system jointed to the superstructure wherein the superstructure is adjustable between a lower position (resting position I) on the substructure and an upper position (operating position II) at a spacing from the substructure.

Claims

1. A goods transshipment apparatus, comprising:

a) a mobile substructure having a front end and a rear end;

b) a superstructure rotatable relative to said mobile substructure about a vertical axis of rotation and includes a driver'"'"'s cab and engine compartment;

c) a jib operably connected to said superstructure; and

d) a pair of parallel connecting rods each of which is pivotally connected at a first end thereof to said mobile substructure and at a second end thereof to said superstructure to support said superstructure above said substructure in a higher operating position and to lower said superstructure relative to said substructure in a lower resting position wherein said axis of rotation remains vertical when said superstructure is raised or lowered to the upper operating position or the lower resting position, respectively, and wherein one of said pair of parallel connecting rods rests against said mobile substructure and the other of said parallel connecting rods rests on the ground behind said mobile substructure rear end when said superstructure is in the lower resting position.

2. A goods transshipment apparatus as in claim 1 and wherein said parallel connecting rods have substantially the same length.

3. A goods transshipment apparatus as in claim 1 and wherein said superstructure is provided with a subframe to which said parallel connecting rods are pivotally connected at opposite ends thereof, said subframe having a horizontally extending first section and a second section extending diagonally downward from said first section, one of said parallel connecting rods is pivotally connected to said first section and the other of said parallel connecting rods is pivotally connected to said second section.

4. A goods transshipment apparatus as in claim 1 and wherein said mobile substructure is provided with an endless track drive.

5. A goods transshipment apparatus as in claim 4 and wherein said endless track drive has an adjustable track width, said track width adjusted by telescopic guides.

6. A goods transshipment apparatus as in claim 1 and wherein said mobile substructure is provided with a wheeled drive having at least two wheel axles.

7. A goods transshipment apparatus as in claim 6 and further including:

a) at least one pair of support elements adapted to be selectively lowered into an extended ground engaging position from said transshipment apparatus so as to prevent tilting of said transshipment apparatus when said superstructure is in the upper operating position, the distance of at least one of said wheel axles from a rotational axis of said superstructure extending perpendicular thereto is greater than or equal to the distance between the rotational axis and said at least one pair of support elements when in the lowered ground engaging position.

8. A goods transshipment apparatus as in claim 7 and wherein said at least one pair of support elements are arranged between said at least two wheel axles.

9. A goods transshipment apparatus as in claim 8 and further including:

a) a second pair of support elements extending from said mobile substructure at one end thereof.

10. A goods transshipment apparatus as in claim 1 and wherein at least one of said pair of parallel connecting rods is a four point connecting rod.

11. A goods transshipment apparatus as in claim 1 and wherein at least one of said pair of parallel connecting rods is a three point connecting rod.

12. A goods transshipment apparatus as in claim 1 and wherein when said superstructure is in the upper operating position, said pair of parallel connecting rods are positioned at an angle of inclination between about 0 degree and about 20 degree to the vertical.

13. A goods transshipment apparatus as in claim 1 and wherein said apparatus is adapted to be driven when said superstructure is in a partly lowered intermediate position.

14. A goods transshipment apparatus as in claim 1 and wherein said jib includes a loading arm and a grab member operatively associated therewith.

15. A goods transshipment apparatus as in claim 1 wherein said mobile substructure is provided with a central undercarriage member to which said parallel connecting rods are pivotally connected.

16. A goods transshipment apparatus as in claim 1 and further including:

a) a control cylinder operatively associated with said pair of parallel connecting rods for moving the same.

17. A goods transshipment apparatus as in claim 1 and wherein said superstructure is moved relative to said substructure between the lower resting and upper operating positions in the manner of a parallel linkage or parallelogram upon movement of at least one of said pair of parallel connecting rods.

18. A goods transshipment apparatus as in claim 1 and wherein one of said parallel connecting rods has a bent configuration.

19. A goods transshipment apparatus, said apparatus comprising:

a) a mobile substructure having a front end and a rear end;

b) a superstructure rotatable relative to said mobile substructure and includes a driver'"'"'s cab and engine compartment;

c) a jib operably connected to said superstructure; and

d) a connecting rod arrangement for selectively moving said superstructure relative to said mobile substructure between a lower resting position and an upper operating position said connecting rod arrangement comprising a pair of connecting rods each of which is pivotally connected at a first end thereof to said mobile substructure and at a second end thereof to said superstructure, the pivotal connections at each of said pair of connecting rods defining a parallelogram and wherein one of said pair of connecting rods rest on said substructure and the other of said pair of connecting rods rests on the ground behind said substructure when said superstructure is in the lower resting position.
