All four embodiments of a vehicle shown in the figures for the transport of Prefabricated room cells 5, here prefabricated garages, have a vehicle frame 2 mounted on wheels 1 with driver's cab 3 and pairs of hydraulic supports arranged in the front and rear areas 4 on. which when loading or unloading the room cell 5, the vehicle stationary on the ground Let 6 rest. In the drawings, these supports 4 are shown in each retracted position.

A hydraulic lifting device 6 is by means of a slide 7 between a pick-up position and a set-down position (FIG. 3 for the first embodiment) and a transport position according to FIG. 1 for the first embodiment, F i g. 4 for the second embodiment F i g. 7 for the third embodiment and FIG. 11 for the fourth embodiment can be displaced along the vehicle frame 2. For this purpose, on the vehicle frame 2 an auxiliary frame 8 is expediently arranged. Furthermore, a support arm 9 engaging the room cell 5 is provided which can be raised and lowered essentially vertically ziim the vehicle frame

In all of the embodiments, the support arm 9 is in the pick-up and set-down position above the Room cell 5 arranged This applies to both picking up and setting down from or on the floor as well as that in fig. 2,5,6 and 8 in the respective embodiments shown picking up or setting down on or from the vehicle.

The support arm 9 is displaceable in the direction of its longitudinal axis 13 in a sliding bearing 14 arranged on the lifting device 6 (double arrow E). Furthermore, the support arm 9 can be displaced parallel to itself in the vertical direction (double arrow D).

In the embodiments shown, the slide 7 is guided on the auxiliary frame 8 by means of roller guides 12 and is displaceable in the direction of the double arrow A.

The configurations described above are common to all four illustrated embodiments.

The first three embodiments furthermore have a rotatability of the lifting device 6 according to double arrow B by means of a pivot bearing 10. Furthermore, a support device 17 which can be pivoted about the vertical axis 16 is expediently provided at the support end 15 of the support arm 9 and enables pivoting to both sides in the direction of the double arrow C (see FIG. 3 for the first embodiment).

The pivot bearing 10 provided on the slide 7 in the first three embodiments enables a Rotation of the lifting device 6 by at least approximately 360 ° around the vertical axis of the lifting device 6.

In the case of the FIGS. 1 and 2, the hydraulic lifting device 6 has a first embodiment shown Piston-cylinder unit 1 "of relatively large diameter, with its cylinder on the pivot bearing 10 of the carriage 7 and with the free piston end on the sliding bearing 14 of the support arm 9 is attached.

The function of this embodiment is as follows:

To accommodate a room cell 5, the piston-cylinder unit 18 first moves the sliding bearing 14 with the support arm 9 in the direction of the double arrow D upwards to a height above the ceiling 19 of the room cell 5 (here a prefabricated garage), whereupon the slide 7 opens the subframe 8 moves to the rear end of the vehicle until the free end 15 of the support arm is approximately above the center of gravity of the room cell 5 (FIG. 3). Subsequently, the room cell 5 is anchored in a suitable manner on the carrying device 17, which can be done in the most varied of ways and is shown in FIG. 2 at 20 is only indicated by dash-dotted lines, it being possible for fastening holes 21 or the like to be provided in the ceiling 19. Subsequently, the room cell 5 is raised by means of the support device 17 until the lifting device 6 with the support arm 9 and the room cell 5 is in the position shown in FIG. 2 position shown on the vehicle can be moved. The drive of the carriage 7 required for this is not shown.

When the room cell 5 was picked up from the ground, it was in the position shown in FIG. 3 position shown with solid lines, then no rotation or pivoting in the direction of arrow C or in the direction of arrow B is required. If, however, it was in one of the three positions oc, β or y indicated by dash-dotted lines, a corresponding pivoting of the support device 17 and / or the takes place after the lifting

Lifting device β by means of the pivot bearing 10 before the carriage 7 returns to the position shown in FIG moves. As Figure 3 clearly shows, is the described The device is very mobile and maneuverable due to the possibilities shown, which means that the limited Mobility of the vehicle itself, especially in cramped conditions, is completely compensated for. By the support arm 9 which can be displaced in the sliding bearing 14, this maneuverability is still supported.

During the subsequent transport, the support arm 9 in the embodiment shown can be fitted with a prefabricated garage having an opening 22 as a room cell 5 in the form shown in FIG. 1 into the interior of the room cell, by first pulling the support arm 9 into the sliding bearing 14 and, after lowering it by means of the lifting device 6, pushing it back in the direction of the arrow (see double arrow E). This takes place in accordance with the appropriate load distribution between the front and rear axles.

In the case of the FIGS. 4 and 5, the sliding bearing 14 is pivotably connected to the piston end 23 by means of a horizontal transverse axis 24. A further piston-cylinder unit 25 is also provided, which is supported in the vertical longitudinal center plane of the support arm 9 via pivot bearings 26, 27 on the one hand on the slide 7 and on the other hand on the sliding bearing 14 at a distance from its horizontal transverse axis 24. FIG. 5 clearly shows the advantage of this embodiment in that the sliding bearing 14 can be pivoted with the support arm 9 in the direction of the arrow F , which additionally increases the maneuverability. For example, cases are conceivable in which the support arm 9 or the sliding bearing 14 in the area of the driver's cab 3 cannot be raised as far (for example in a gate passage, under a bridge or the like), as is the case in individual cases for proper unloading of the cubicle 5 and bringing it to the stand on the ground 6 would be required. In its further features, this embodiment corresponds to the first corresponding to FIG. F i g. 1 to 3.

From the F i g. 6 and 7 shows a third embodiment in which the hydraulic lifting device 6 a first and a second piston-cylinder unit 28 and 29, which in the vertical longitudinal center plane of the support arm 9 each at a distance from one another on the one hand on the pivot bearing 10 of the carriage 7 and on the other hand on the sliding bearing 14 of the support arm 9 are hinged.

Furthermore, a third piston-cylinder unit 30 is arranged as a supporting cross-member in the same plane that on the one hand on the pivot bearing 10 and on the other hand at the end 31 of the cylinder facing away from the pivot bearing 10 first piston-cylinder unit 28 is articulated. This configuration makes it possible not only in the same way as in the second embodiment, to lift the sliding bearing 14 with the support arm 9 and in the direction of the double arrow F up or down, but also that Push-through bearing 14 to move together with the support arm 9 with respect to the vehicle forwards or backwards. This can be seen very clearly if the from FIG. 6 emergent position of the lifting device 6 with of those in FIG. 7 compares in which the same is rotated by 180 ° about the vertical axis 11 of the pivot bearing 10 is, especially if one in Figures 6 and 7 the The extension lengths shown of the piston rod of the third piston-cylinder unit 30 are compared.

For the articulation of the second and the third cylinder on the pivot bearing 10, a common one is expedient Pivot axis 32 is provided, which serves to simplify construction

In all cases, the from F i g. 3 particularly clearly to be seen support device 17 in the form of a double Horizontal traverse with individual traverses 33 and 34 with four load-bearing points 20 can be provided.

The technical means with which a pivoting of the support device 17 is effected according to double arrow C, the rotation of the pivot bearing 10 according to double arrow B and the displacement of the carriage 7 according to double arrow A are conventional and do not need to be explained.

It can be useful to use the existing displaceability of the support arm 9 in the sliding bearing 14 also provide a telescopic design of the support arm 9, such that it is stationary Can lengthen or shorten the position on the sliding bearing 14.

The pulleys and cables required to raise and lower the support device 17 are conventional and have therefore largely been omitted as they do not require any further explanation. The on Support arm 9 indicated in the figures pulleys are therefore not designated in more detail because their function is the Expert is familiar

The third embodiment according to FIG. 6 and 7 is only to be added that in the absence of the garage door opening 22 in a closed cell, the rear roller 35 must be pivotable in the direction of the double arrow G with the proportions shown. However, if the opening 22 is present, as shown, then the pivoting can be omitted, as indicated by dash-dotted lines.

In the fourth embodiment shown in FIGS. 8-11, a hydraulic lifting device with two first piston-cylinder units 36, which are spaced α from one another in the transverse direction, and a second piston-cylinder unit 37 is provided. The two first piston-cylinder units 36 and the second piston-cylinder unit 37 are spaced apart in the longitudinal direction of the support arm 9 and are articulated on the one hand on the slide 7 and on the other hand on the sliding bearing 14 of the support arm 9. Furthermore, two crossing support cross members 38 are provided, which are arranged essentially in the plane of the two first piston-cylinder units 36 and on the one hand on the carriage 7 and on the other hand on the ends 39 of the cylinders 40 of these two first piston-cylinders facing away from the carriage 7 Units 36 are articulated. F i g. 9 shows this very clearly, the second piston-cylinder unit 37, which lies behind the plane of the drawing, has been omitted for the sake of clarity Additional links 38 'can be seen between the base 42 in the region of the piston-cylinder unit 37 and the ends 39 of the cylinder 40, which in turn are shown in FIG. 9 lie behind the cylinders 40 and are not visible.

The carriage 7 consists of two separate base traverses 41, 42, both ends of which are each slidably mounted on the vehicle or subframe. For the sake of clarity, with regard to F i g. 9 only the ends 43 and 44 of the base traverse 41 have been designated in more detail. Between

At least one of the two base traverses 41, 42 is shown in FIG. 8 piston-cylinder unit 45 is provided for optionally changing the distance D between the two base cross members 41, 42.

In particular in this fourth embodiment, the support arm 9 in the sliding bearing 14 can be moved so far and the sliding bearing 14 with the support arm 9 by means of the lifting device 6 in the vertical (double arrow D) so far that both the support arm 9 and the sliding bearing 14 in the Transport position are arranged overall below the horizontal plane of the upper edge 46 of the room cell 5.

Since the pivot bearing 10 has been dispensed with in this embodiment, the support arm 9 is for the purpose of transition from its operating position into the transport position (FIG. 11) completely into the sliding bearing 14 retractable. Like F i g. 8 shows, the support arm 9 is constructed in several parts (see parts 47 and 48) and Can be extended and shortened telescopically (Fig. 11).

In the present case, only limited pivotability is sufficient, as is the case with the fourth Embodiment according to FIGS. 8-11 from FIG. 9 and 10 emerges. For this purpose there is one end of the sliding bearing 14 on the piston rod 49 of the piston-cylinder unit 37 by means of a journal bearing 50 pivotally mounted in the direction of the double arrow /, while the rear end of the sliding bearing 14 by means of a piston-cylinder unit 51 along one of the ends of the pistons 52 and 53 of the piston-cylinder units 36 interconnecting traverse 54 in the direction of the double arrow // is displaceable It understands that in a manner not shown between the slider 55 and the associated end of the sliding bearing 14 a kind of journal bearing can be provided, which is not shown.

This form of limited pivotability of the support arm 9 about the vertical axis 56 (Fig. 10) can be in the Usually enough to have sufficient maneuverability and versatility when loading and unloading Ensure room cell 5. The favorable distribution of the axle load is made possible by the fact that it can be fully pushed in of the support arm 9 in the sliding bearing 14 and the telescopic ability of the support arm 9 is made available.

In the embodiments described, hydraulic lifting and moving devices are used found. It goes without saying, however, that electrical, pneumatic and possibly also mechanical for this purpose Facilities, the latter in the form of racks with pinions, spindles or the like, come into question.
