[0027] In the drawing:

[0029] FIG. 2 shows the load-handling vehicle having the loading arm assembly in a deployed position when loading an ISO container, in a schematic lateral view;

[0030] FIG. 3 shows the load-handling vehicle when loading a roll-on/roll-off flatbed which is gripped by the loading arm assembly by means of a gripping hook, in a schematic lateral view;

[0031] FIG. 4 shows the loading arm assembly without the gripping hook, in a schematic rear view;

[0032] FIG. 5 shows the loading arm assembly according to FIG. 4, in a schematic lateral view; and

[0033] FIG. 6 shows a universal joint of the loading arm assembly, in a schematic sectional illustration, said universal joint rotatably connecting a crossbeam and an auxiliary arm.

[0034] A load-handling vehicle 1 can be readily seen in FIGS. 1 to 3. The load-handling vehicle 1 has a truck bed 2 and a cab 3. The load-handling vehicle 1 is configured in particular for defence applications. To this end, the cab 3 can be configured so as to be armoured, for example. The load-handling vehicle 1 is in particular suitable not only for on-road use but also for off-road use.

[0035] By way of the load-handling vehicle 1, dissimilar roll-on/roll-off containers 4 such as, for example, an ISO container 5 or a transportation container 6 having a hook 7 can now be loaded. To this end, the load-handling vehicle 1 has a loading arm assembly 8 which is suitable for loading ISO containers 5 as well as transportation containers 6 having a hook 7.

[0036] The loading arm assembly 8 has a main arm 9, wherein the main arm 9 by way of one end thereof is pivotably articulated on the truck bed 2, in particular on a vehicle chassis or the like. A drive, in particular in the form of a hydraulically activated thrust bar 10, is present in order for the main arm 9 to be pivoted. Alternatively, a pneumatic or motorized drive can be provided. The main arm 9 in the longitudinal direction thereof is configured in particular so as to be telescopic so as to be able to receive roll-on/roll-off containers 4 of dissimilar lengths. An auxiliary arm 11 is disposed on the other end of the telescopic part of the main arm 9, wherein the auxiliary arm 11 extends so as to be substantially perpendicular to the main arm 9. The auxiliary arm 11 herein is fastened to the main arm at a fixed angle. The auxiliary arm 11 is in particular fastened to a telescopic part of the main arm 9. This design embodiment can also be referred to as a thrust hook. The auxiliary arm 11 can also be referred to as a thrust arm. It is possible for the auxiliary arm 11 to be configured as an articulated arm and to be pivotably disposed on the main arm 9 (not illustrated).

[0037] The auxiliary arm 11 now has two gripper systems. On the one hand, a gripper system for gripping ISO containers 5 is present, and a gripper system for gripping transportation containers 6 having a hook 7 is present, on the other hand. An adapter can be dispensed with on account thereof.

[0038] The auxiliary arm 11 here has two outer sleeves 12, 13 in which in each case one displaceable internal part 14, 15 is disposed in a telescopic manner. A gripping hook 16 is disposed on the end of the second internal part 15. The gripping hook 16 is thus likewise telescopic in the transverse direction relative to the main arm.

[0039] The other gripper system for gripping ISO containers will be explained in more detail hereunder by means of FIGS. 4 and 5.

[0040] The telescopic capability of the auxiliary arm 11 is indicated by the arrow 17 in FIGS. 4 and 5. A crossbeam 19 is disposed on the free end of the first internal part 14. The crossbeam 19 herein, substantially by way of the centre thereof, is disposed on the end of the first internal part 14. The crossbeam 19 has a first crossbeam region 20 and a second crossbeam region 21, each in FIG. 4 laterally protruding in the longitudinal direction of the crossbeam to the left and the right beyond the internal part 14. Each of the two crossbeam regions 20, 21 is configured so as to be telescopic. The telescopic capability is indicated by the arrows 22, 23. Corner grippers 24, 25 which are in each case pivotable about the longitudinal axis of the crossbeam 19, this being indicated by the arrow 26, are disposed on the free ends of the crossbeam regions 20, 21. The respective movements of the crossbeam regions 20, 21, or of the corner grippers 24, 25, respectively, are performed in a hydraulic, pneumatic, or motorized manner.

[0041] It is a particular advantage of the loading arm assembly 8 that the crossbeam 19 is pivotable about two axes relative to the auxiliary arm 11, specifically relative to the internal part 14 here. This is achieved in that the crossbeam 19 is connected to the internal part 14 by way of a universal joint 27 (cf. FIG. 6). In an alternative design embodiment, a ball joint (not illustrated) can be used instead of a universal joint 27, for example.

[0042] A housing 28 is disposed on the end of the internal part 14, wherein the universal joint 27 is disposed within the housing 28. The housing 28 has three assembly openings 29, 30, 31. The assembly openings 29 and 31 herein are disposed on the front and the rear side (not referred to in more detail) of the housing 28, and the assembly opening 30 is disposed on the upper side. Furthermore, the housing 28 has in each case two engagement openings such that the crossbeam 19 can engage through the housing 28.

[0043] The universal joint 27 has a crosspiece 32, wherein the crosspiece 32 is formed by four axle stumps 33, 34, 35, 36 and a central piece 37. The two axle stumps 33 and 35, and the two axle stumps 34 and 36, are in each case disposed so as to be mutually aligned. On account thereof, two axle stump pairs 33, 35, and 34, 36, respectively, that cross in an orthogonal manner are formed. The axle stumps 33, 34, 35, 36 are connected to a central piece 37. The axle stumps 33 to 36 are in particular connected to the central piece 37 by a screw connection 38, 39, 40, 41. The axle stumps 33 and 35 by way of a bearing shell 42, 43 are disposed so as to be pivotable relative to the crossbeam 19. Respective bearing shells 44, 45 are disposed in the assembly openings 29, 31, wherein the bearing shells 44, 45 by way of in each case one collar (not referred to in more detail) bear externally on the housing 28. The bearing shells 44, 45 herein form a stepped receptacle in which the heads 46, 47 are disposed. The heads 46, 47 herein have a larger diameter than the bore of the bearing shells 42 to 45.

[0044] On account thereof, the crossbeam 19 is pivotable about the longitudinal axis 48 of the auxiliary arm 11 as well as about a transverse axis 49. The transverse axis 49 herein extends so as to be transverse to the auxiliary arm 11 as well as transverse to the crossbeam 19. The longitudinal axis 48 and the transverse axis 49 are mutually orthogonal.

[0045] Pivoting the crossbeam 19 about the longitudinal axis 48 enables a compensation when the load-handling vehicle 1 and the roll-on/roll-off container 4 in the form of the ISO container 5 are at an angle and are not mutually aligned. Pivoting the crossbeam 19 about the transverse axis 49 enables a compensation when the ISO container is tilted about its longitudinal axis because it has sunken into soft ground, for example.

[0046] On account of this potential pivoting capability of the crossbeam 19 about the longitudinal axis 48 (cf. arrow 50, FIG. 4) and the transverse axis 49 (cf. arrow 51, FIGS. 4 and 5), the ISO container 5 can be securely received by the loading arm assembly 8 even in difficult environmental conditions, for example in the off-road use of respective ISO containers 5.

[0047] A particular advantage of this loading arm assembly 8 lies in that it is possible for the ISO containers 5 and/or the transportation containers 6 to be fully automatically loaded and unloaded by way of the corresponding hook 7.

[0048] It is neither necessary for an adapter for modifying ISO containers 5 to a gripping hook system to have to be manually used, nor is it necessary for the load-handling vehicle 1 to have to be aligned precisely with the ISO container 5, or for the ISO container to have to be at the same angle as the load-handling vehicle 1.

[0049] The disadvantages mentioned at the outset are thus avoided and corresponding advantages are achieved.
