Abstract

A lifting device for vehicles, machines, erecting units or the like has at least one lifting element, which has at least one first mounting point and opposite this at least one second mounting point which is arranged on a load receiving section. The lifting unit and the at least one load receiving section form a first modular unit. The first modular unit has, at least one end of the load receiving section, a connecting section for receiving at least one further modular unit with at least one connecting section arranged thereon.

Claims

1. Lifting device for vehicles, machines, erecting units or the like, comprising at least one lifting element (14), which has at least one first mounting point (15) and opposite this at least one second mounting point which is arranged on at least one load receiving section (23), wherein the lifting unit (14) and the at least one load receiving section (23) form a first modular unit (21);

and wherein the first modular unit (21) has, at least one end of the load receiving section (23), a connecting section (24) for receiving at least one further modular unit (21, 22) with at least one connecting section (24, 27) arranged thereon.

2. Lifting device according to claim 1, wherein the further modular unit (21) is formed substantially identically to the first modular unit (21).

3. Lifting device according to claim 1, wherein the at least one further modular unit (22) comprises an intermediate piece (26) for receiving a load, having two connecting sections (27).

4. Lifting device according to claim 3, wherein the length of the intermediate piece (26) of the further modular unit (22) is equal to or smaller than that of the load receiving section (23) of the first modular unit (21).

5. Lifting device according to claim 1, wherein the lifting element (14) of the first modular unit (21) is a half shears and at least two first modular units (21) are provided for forming a lifting device (13).

6. Lifting device according to claim 5, wherein the at least two first modular units (21) are arranged mirror-imagewise of one another.

7. Lifting device according to claim 1, wherein the connecting sections (24, 27) are connected together at least one of positively and frictionally.

8. Lifting device according to claim 1, wherein a flange connection (28) is provided along a separation plane (33) between the modular units (21, 22), and has bores for releasably receiving connecting elements.

9. Lifting device according to claim 8, wherein the flange connection (28) is arranged as a plate (31) at right angles to the load receiving section (23).

10. Lifting device according to claim 9, wherein the flange connection (28) is supported by reinforcing ribs (34) on an underside of the load receiving section (23).

11. Lifting device according to claim 1, wherein the connecting sections (24, 27) have at least one support point (38) or at least one support surface, opposite an upper side (18) of the load receiver (16).

12. Lifting device according to claim 11, wherein the at least one support point (38) or the at least one support surface is spaced apart from the upper side (18) of the load receiving device (16) such that the load receiver (16) in an inoperative position is arranged running horizontally and is arranged supported on a road surface (19).

13. Lifting device according to claim 7, wherein bores (39, 47) for connecting elements are provided at least in outer edge fibers of the connecting sections (24, 27).

14. Lifting device according to claim 1, wherein fastening elements (37, 46, 52) are provided on an underside of the load receiving sections (23), and extend at least partially beyond the separation plane (33) and engage on the respective opposite load receiving section (23) or on the intermediate piece (26).

15. Lifting device according to claim 14, wherein profiles (37) which are provided for receiving a movable slide of the lifting unit (14) extend over the separation plane (33).

16. Lifting device according to claim 1, wherein each connecting section (24, 27) has centering elements (41) for aligning the modular elements (21, 22).
