Description

[0001] The invention relates to a platform for storing and / or loading semi-trailers, a platform stack, and a method for loading semi-trailers.

[0002] A lifting device for loading semi-trailers is known from WO 2016 / 141399 A1. The lifting device has, in particular, a support frame with upwardly projecting side members, which are connected by means of a plurality of crossbeams as contact surfaces and, furthermore, by means of at least one support device. Two crossbeams are spaced apart from each other such that the wheels of the semi-trailer can be placed between them. It is further disclosed that the lifting device can be set up directly on a terminal floor by means of the contact surfaces.

[0003] Furthermore, EP 3 623 244 A1 discloses a method for loading a semi-trailer onto a flatcar. In this method, the semi-trailer is driven forwards or backwards by a tractor unit directly into a support frame. The support frame is then placed onto the flatcar using a lifting device. The support frame has longitudinal elements connected by a plurality of crossbeams. Each pair of spaced-apart crossbeams forms pockets between them for receiving the wheels of one axle. For three axles of a semi-trailer, four crossbeams are provided accordingly, with the wheels remaining in the pockets after the support frame has been positioned on the flatcar.

[0004] Support devices of the previously known type have a high dead weight. They have separate pockets for each axle of a semi-trailer to accommodate the wheels, with the pockets being formed by a number of crossbeams. Consequently, such support devices also have low efficiency, as the maximum payload is reduced due to the increased dead weight. Finally, known support devices are also cumbersome to handle. In particular, additional means are generally required to secure the semi-trailer to the support device when it rests on a flatbed or pocket trolley.

[0005] The invention is therefore based on the objective of providing a platform that has a low weight and is easy and safe to handle and flexible in its application.

[0006] The invention solves the problem with a platform according to claim 1, a platform stack according to claim 12 and a method according to claim 14. The dependent claims relate to advantageous embodiments.

[0007] The platform according to the invention for storing and / or loading semi-trailers has two side elements extending parallel to each other in a longitudinal direction and spaced apart from each other transversely in a transverse direction. Within the scope of the invention, the side elements can be designed, in particular, as beam supports, profile supports, crossbeams, or especially as support plates.

[0008] According to the invention, a plurality of stop elements are arranged on each of the side elements. Within the scope of the invention, stop elements can be understood as connecting elements such as gripping edges or similar, which can be brought into operative connection with a lifting device for lifting the platform. The platform can thus be lifted and loaded, in particular by crane or other means, using the stop elements. The stop elements can be understood either as an integral part of the respective side element or as a part separately connected to the respective side element.

[0009] The platform according to the invention further comprises a first base element and a second base element, which are arranged longitudinally spaced apart from each other on the side elements and by means of which the two side elements are connected to each other in the transverse direction. According to the invention, the base elements and the side elements can be formed integrally or be separate and thus securely connected to each other.

[0010] According to the invention, the first floor element also has a wheel recess adjacent to each of the side elements and a raised central tunnel between the two wheel recesses. The wheel recesses are designed as openings or as cutouts in the first floor element.

[0011] The platform according to the invention has a low tare weight and therefore enables the efficient storage and / or loading of semi-trailers, even with increased loads. The platform is particularly simple in design and achieves these advantages primarily by accommodating a semi-trailer using only one pair of wheel recesses. Thanks to the central tunnel, the platform is also flexibly suited for particularly secure loading onto pocket trolleys.

[0012] The side elements can be designed in such a way that they extend away from the first and second base elements. Preferably, the side elements can be designed as longitudinally elongated support plates, as mentioned above, which extend away from the first and second base elements at a certain height.

[0013] The central tunnel can be characterized, for example, by the fact that the material thickness of the first floor element in the area of ​​the central tunnel is less than in the areas where the wheel recesses are formed. In this case, the first floor element can have a flat surface. Furthermore, the first floor element can also be designed, in particular, such that the central tunnel is formed as a tunnel-like bulge or profile of the first floor element. The first floor element can preferably be formed from one or more support plates.

[0014] In a cross-sectional view through the first or second base element, the platform preferably has a shell- or trough-like shape. The first base element may have a recess due to the central tunnel, which can be tunnel-like in the longitudinal direction. The platform is preferably axially symmetrical about a central longitudinal axis. The central tunnel is therefore particularly preferably arranged centrally between the two side elements. If the first base element is, for example, made of a support plate as described above, it is possible that the first base element is W-shaped in the aforementioned cross-sectional view, with the central tunnel, particularly in a flattened form, forming the central point of the W. The first base element can be connected to the side elements at its outer ends.The side elements can preferably be connected to the first floor element in such a way that, in the aforementioned sectional view, the entire platform is W-shaped. In a sectional view analogously in the transverse direction through the second floor element, the platform can then preferably be U-shaped. It is also conceivable that the first floor element is formed from, for example, a pair of beams or similar components, with the beams preferably having a central tunnel located midway between the side elements.

[0015] The spacing of the platform's side elements in the transverse direction can be determined, in particular, by the width of the semi-trailer to be supported and, furthermore, by the width of standard pocket trolleys onto which the platform, including the semi-trailer mounted on it, can be loaded. The platform is preferably made of steel or a similarly robust material. The side elements can preferably be made of the same material as, or alternatively, of a different material than, the first and second base elements. This also applies, for example, to the connection between the two base elements. The two base elements can preferably be bonded to the side elements. In an embodiment in which the side elements and the two base elements are formed in one piece, it is possible, for example, for the platform to be formed from a correspondingly shaped support plate.

[0016] According to the invention, the first and / or the second floor element are arranged longitudinally at their ends against the side elements such that the longitudinal ends of the side elements are abutted by the longitudinal ends of the first and / or the second floor element, respectively, when viewed transversely. The side elements thus form, for example, a closing front of the platform together with the first and / or the second floor element when viewed longitudinally. It is particularly conceivable that the second floor element has an extended section that projects beyond a longitudinal end of the side elements.

[0017] The second floor element can preferably be formed from one or more support plates, which are formed into a preferred embodiment. If several support plates are provided, the individual plates can be bonded together. Particularly preferably, the second floor element can be bent upwards at its lateral ends towards the side elements, and thus be bonded to the side elements, particularly by means of a material connection. It is further possible that the second floor element is essentially flat between the aforementioned bent-up ends. Furthermore, the second floor element can be designed in such a way that a semi-trailer with its landing gear and / or other support structure can be safely parked on it.

[0018] The second floor element preferably has a bottom surface which lies in the same plane as the bottom surface of the first floor element in the area of ​​the wheel recesses. The bottom surface of the first floor element in the area of ​​the central tunnel is spaced vertically from this plane.

[0019] The platform's base level allows it to be placed directly on a surface, such as a terminal corridor. It then allows a semi-trailer to be driven directly onto the platform by a tractor unit, without the need for an additional ramp. If the semi-trailer has three rear axles, the wheels of the middle axle are preferentially accommodated in the wheel recesses. The wheels of the front axle can be supported by their treads, which face rearward towards the middle axle, against the front outer edge of their respective wheel recesses. The wheels of the rear axle can, in turn, be supported by their treads, which face forward towards the middle axle, against the rear outer edge of their respective wheel recesses. The rear of the semi-trailer can therefore, for example, overhang the platform.If the platform rests on a terminal floor with its base level, a semi-trailer loaded onto the platform can be positioned with its wheel treads on the terminal floor, while remaining supported by its landing gear and / or other support structure against the second floor element. The wheel recesses are therefore preferably dimensioned such that they only come into contact with the wheel treads during loading, i.e., when the platform is lifted, as described above. When the platform is lifted, the wheels can preferably be positively engaged in the wheel recesses. If the wheel recesses are particularly rectangular, they can each have a width in the transverse direction of 500 mm to 800 mm, preferably 550 mm to 700 mm, and most preferably 625 mm to 675 mm. The wheel recesses can each have a longitudinal length in the range of 550mm to 850mm, preferably 600mm to 750mm, particularly preferably 675mm to 725mm.This makes it possible, for example, to store and / or load semi-trailers with twin tires using the platform, despite the efficient design of the wheel recesses.

[0020] Particularly when loading a semi-trailer, the wheel recesses can be subjected to considerable weight forces from the wheels of one axle of the semi-trailer. It can therefore be advantageous if the load of the wheels in the wheel recesses can be transferred directly to the first floor element or the corresponding side element on all sides. According to the invention, the two wheel recesses are therefore designed as recesses or openings in the first floor element, which are bounded longitudinally by a pair of transversely extending crossbars of the first floor element, and transversely by one of the side elements on the outside and by the central tunnel on the inside.

[0021] The central tunnel can be advantageously designed, as mentioned above, to be securely placed on the central support of a trolley. The first base element can then rest laterally against this central support in the area of ​​the wheel recesses. According to a further preferred embodiment, the first base element therefore has an underside which, in the area of ​​the central tunnel, is vertically separated from the underside in the area of ​​the wheel recesses by a tunnel height.

[0022] Analogous to the aforementioned case of a platform with a semi-trailer parked on, for example, a terminal corridor, it can be advantageous if the tunnel height is designed such that a semi-trailer loaded onto a trolley via the platform can support itself with the treads of its wheels on the floor of the trolley. This also has the advantage that the platform does not increase the load height of the semi-trailer on the trolley. According to a further preferred embodiment, the central tunnel therefore has a tunnel height in the range of 3 cm to 12 cm, preferably 4 cm to 10 cm, and most preferably 5 cm to 8 cm. The platform can, for example, be considered a dead unit. This means that the platform on the terminal corridor and / or on the trolley, for example, has neither an influence on the load height of the corresponding semi-trailer nor a detrimental influence on the load securing. In particular, for example,No additional means of load securing are needed on a pocket trolley because of the use of the platform.

[0023] It is further advantageous for the flexible positioning of the platform on a trolley if the central tunnel has lateral play on the aforementioned central support of the trolley. According to a further preferred embodiment, the central tunnel therefore has a width, measured in the transverse direction, in the range of 80 cm to 120 cm, preferably 85 cm to 110 cm, and particularly preferably 90 cm to 100 cm.

[0024] It can be further advantageous for the stability of the platform and for loading a semi-trailer onto the platform if the first and / or the second floor element have a top surface that lies in the same plane. In particular, it can be advantageous to construct the first floor element in the area of ​​the wheel recesses up to the height of the top surface of the first floor element in the area of ​​the central tunnel. According to a further preferred embodiment, extension elements are therefore arranged on the first floor element and / or on the second floor element.

[0025] If, for example, the second floor element has a top surface that lies in the same plane as the top surface of the first floor element in the area of ​​the wheel recesses, then it is advantageous to also arrange support elements on the top surface of the second floor element. These support elements can be designed, for example, as beam supports, hollow profile supports, or similar. Preferably, two such support elements can be provided for each wheel recess on the first floor element, mounted on the corresponding cross members that define the wheel recesses longitudinally. The top surfaces of the support elements, at least on the first floor element, are particularly preferably in the same plane as the top surface of the first floor element in the area of ​​the central tunnel. The top surfaces of the support elements on the second floor element can also preferably be arranged in the same plane. The support elements can preferably be trapezoidal in cross-section along the longitudinal direction of the platform.However, it is particularly possible that the extension elements of the second floor element have a different trapezoidal shape than the extension elements of the first floor element, especially in the form of a parallelogram. Trapezoidal extension elements, for example, facilitate loading the semi-trailer onto the platform without an additional ramp. At the same time, this can help protect the wheels, and especially the tires of the semi-trailer, during loading.

[0026] It can also be advantageous if semi-trailers of different designs, with their landing gear and / or corresponding individual support structures, can be securely and flexibly positioned against the second floor element. According to a further preferred embodiment, the extension elements of the second floor element therefore have recesses, in particular elongated holes, for the passage of support elements of the semi-trailer. The support elements can thus be flexibly positioned along the width. Furthermore, it is also possible to more easily balance the support elements vertically. In particular, the support elements can be passed through the extension element of the second floor element and supported on the upper surface of the second floor element. It is also possible for the second floor element to have recesses analogous to those of the extension element.Support elements can then also be inserted through the second floor element, so that the semi-trailer, for example, can also be additionally supported on the pocket wagon with its own support structure.

[0027] For precise and reliable positioning of the platform within a pocket trolley, it can be advantageous if the transition from the first and / or second base element to the side elements is continuous, i.e., not abruptly at right angles. Right-angled transitions are subject to increased mechanical and abrasive stress, making them more susceptible to mechanical failure or damage. A continuous transition can therefore further increase the platform's durability. According to another preferred embodiment, the side elements and the first and / or second base element each transition into one another via a rounded, or at least a chamfered, transition section. It is conceivable that the side elements and the two base elements are formed in one piece from, for example, a carrier plate, as described above.The transition section can be easily folded out during the forming of the carrier sheet into the desired configuration. However, it is also possible for the side elements and the two bottom elements to be separate, with at least one of each element having a corresponding transition section. The separate side and bottom elements can then be bonded together at this transition section.

[0028] If the side elements are designed as support plates as described above, it can be advantageous to design them in a truss-like structure, particularly to further reduce the platform's weight. According to a further preferred embodiment, the side elements therefore have recesses. These recesses can be designed as circular, pill-shaped, and / or oval holes, which is particularly advantageous from a structural point of view. It is also conceivable to provide other recess shapes, such as polygons. These preferably have rounded tips, which in turn can increase the platform's durability.

[0029] To enable even more efficient and flexible use of the platform, it can be advantageous to be able to stack temporarily unused platforms on top of and / or inside each other in a space-saving manner. According to a further preferred embodiment, stacking hooks are therefore provided on the side elements. The stacking hooks can be arranged, in particular, on the stop elements, especially gripping edges, of the platform. Preferably, at least one, and furthermore, several stacking hooks can be provided per stop element. For better load distribution and stability, the stop elements can be arranged in the longitudinal direction in the area of ​​the two base elements. Preferably, two stop elements, especially gripping edges, can be provided per side element.

[0030] The stacking hooks preferably point inwards from the side elements, i.e., towards the central longitudinal axis. It is then possible for a platform to be supported by at least one stacking hook of another platform, with a portion of its underside on the first base element and a portion of its underside on the second base element. Furthermore, it is also possible for a platform to be supported at the aforementioned transition sections by stacking hooks of another platform as described above. The second platform, stacked on top of a first platform, can be positioned between the side elements of the first platform with at least a portion of its two base elements.

[0031] It can be further advantageous to design the stacking hooks in such a way as to prevent damage to loaded semi-trailers. It may be necessary to consider that the platform width is not increased due to the stacking hooks. According to another preferred embodiment, the stacking hooks are therefore designed to pivot between a working position and a rest position. For this purpose, the stacking hooks can be pivotally mounted to the stop elements of the side elements. In the rest position, the stacking hooks can rest against an outer side of the respective stop elements, so that there is no risk of collision with a semi-trailer being loaded. It is also conceivable to pivot the stacking hooks upwards into a different rest position. In the working position, the stacking hooks point inwards as described above.The stacking hooks can be manually pivoted between their rest and working positions. Automating this process is also conceivable. Furthermore, it is possible, for example, for the stacking hooks to be interconnected on a side element and then be manually pivoted together.

[0032] Furthermore, it can be advantageous if the stacking hooks can be secured so that they do not swing out arbitrarily, for example, into the working position. According to another preferred embodiment, the stacking hooks are therefore also equipped with locking means to secure them in their rest position. For this purpose, the stacking hooks can be locked to the respective stop elements or side elements, for example, by means of locking pins or similar devices. It is also conceivable that the stacking hooks can be snapped onto the stop elements. Finally, it is possible that receiving elements are provided on the stop elements in which the stacking hooks can, in turn, be locked.

[0033] The invention further relates to a platform stack. Depending on the embodiment, the preceding features and definitions may also apply to the platforms mentioned below.

[0034] The platform stack according to the invention comprises a first and a second platform for storing and / or loading a semi-trailer. The first and the second platform each have two longitudinally extending side elements, which are connected to each other in a transverse direction by means of a plurality of floor elements.

[0035] According to the invention, a plurality of stacking hooks are formed on the side elements of at least the first platform, wherein the second platform rests on the stacking hooks of the first platform with undersides of the side elements and / or the bottom elements.

[0036] As previously explained, it is possible for the stacking hooks to be pivotably arranged between a rest position and a working position on stop elements, in particular gripping edges, of the respective side elements. The stacking hooks can also be designed to lock in the rest position.

[0037] According to a preferred embodiment, the first and / or the second platform has a first floor element which has a wheel recess adjacent to one of the side elements and a raised central tunnel between the two wheel recesses.

[0038] Finally, the invention relates to a method for loading semi-trailers onto pocket trolleys using a platform as previously defined within the scope of the invention.

[0039] In a first step of the method according to the invention, the semi-trailer is loaded and / or secured on the platform. The semi-trailer can be driven onto the platform, in particular by means of a tractor unit. The wheels of one axle of the semi-trailer are placed in the wheel recesses, with the wheels preferably resting on the ground beneath the platform, so that the semi-trailer can support itself on the ground with the treads of its wheels.

[0040] In a second step of the inventive method, the platform is then lifted at the stop elements. If the stop elements are designed, for example, as gripping edges, the lifting can be carried out, for example, by means of a crane, in particular a gantry crane, or with mobile equipment. During lifting, those wheels of the semi-trailer that were previously placed in the wheel recesses come into contact with the limiting surfaces of the wheel recesses. In the case of a semi-trailer with three rear axles, these can be, in particular, the wheels of the middle axle.

[0041] In a third step of the inventive method, the platform is lowered onto the trolley such that the platform with its central tunnel rests on a central support of the trolley, and the semi-trailer with its tires rests independently on a base of the trolley. The semi-trailer can be further supported on the platform, particularly on the second base element, for example, by its landing gear and / or other support structure. The kingpin of the semi-trailer can, in turn, be supported, for example, on a support bracket of the trolley.

[0042] Features and definitions previously defined for the platform or platform stack can also be applied, by way of example, to the method according to the invention.

[0043] Exemplary embodiments of the inventions are explained below with reference to the figures. The figures show: Fig. 1a perspective view of a platform according to one embodiment; Fig. 2 a side view of the platform according to Fig. 1 ; Fig. 3a a frontal view of the platform according to Fig. 1 in the direction of the first floor element; Fig. 3b a frontal view of the platform according to Fig. 1 in the direction of the second floor element; Fig. 4a a side view of a platform according to an embodiment with a semi-trailer on a pocket wagon in section along a longitudinal axis; Fig. 4b a frontal view of the platform with semi-trailer on a pocket wagon according to Fig. 4a .

[0044] Fig. 1Figure 1 shows an example of a support platform 10, consisting of two side plates 12 extending longitudinally in a longitudinal direction L, which are transversely connected in the transverse direction Q by means of a first base element 16 and a second base element 18. Here, the support platform 10 is, for example, made entirely of steel. The side plates 12 and the two base elements 16 and 18 are each formed from support plates that have been shaped accordingly. The side plates 12 are welded to the two base elements 16 and 18 in the area of ​​a transition section 32, which is not shown in detail here.

[0045] The side plates 12 have recesses 34, particularly for weight reduction. The recesses 34 are shaped differently, for example, circular, pill-shaped oval, or triangular. The triangular recesses 34 have rounded tips.

[0046] Gripping edges 14 are formed on each of the side plates 12, in the area of ​​the two base elements 16, 18, with reference to the longitudinal direction L. The gripping edges 14 can be gripped, for example, by means of a gantry crane, and the support platform 10 can be lifted and loaded, either empty or loaded with a semi-trailer 40 (not shown in detail here). A stacking hook 36 with a securing device (not shown in detail here) is also arranged on each of the gripping edges 14. The stacking hooks 36 can be pivoted between a working and a rest position. For this purpose, the stacking hooks 36 are articulated to the gripping edges 14. Fig. 1For example, the stacking hooks 36 in the area of ​​the second base element 18 are in the operating position, and the stacking hooks 36 in the area of ​​the first base element 16 are in the rest position. The pivoting of the stacking hooks 36 occurs here, for example, in a horizontal plane. In the rest position, the stacking hooks 36 are, for example, each in contact with an outer surface of the corresponding gripping edges 14.

[0047] How Fig. 1The first floor element 16 is further illustrated here as a one-piece support plate. Adjacent to the respective side plate 12, two continuous wheel recesses 20 are formed in the first floor element 16. In the longitudinal direction L, the wheel recesses 20 border on both sides against transverse struts 24 of the first floor element 16. In the transverse direction Q, the wheel recesses 20 are bounded on the outside by a side plate 12 and on the inside by a central tunnel 22. The wheel recesses 20 have a width in the transverse direction Q of, for example, 653 mm and a length in the longitudinal direction L of, for example, 700 mm.

[0048] The first floor element 16 has a bottom surface 28 which is raised in the area of ​​the central tunnel 22 compared to the bottom surface 28 in the area of ​​the wheel recesses 20. The height difference is characterized here in particular by a tunnel height H, which is, for example, 61 mm. The central tunnel 22 also has, for example, a tunnel width B in the transverse direction of 930 mm. The bottom surface 28 in the area of ​​the wheel recesses 20 lies in a horizontal plane.

[0049] Fig. 1Figure 22 further illustrates that the central tunnel 22 has a top surface which lies in a horizontal plane with the top surfaces of the support beams 30, the support beams 30 being arranged on the cross members 24 of the first base element 16. Two cover plates are also arranged on the top surface of the central tunnel 22, which serve in particular to secure the support beams 30. In cross-section along the longitudinal direction L, the support beams 30 each have, for example, a trapezoidal shape. The support beams 30 each have sloping outer surfaces with respect to the longitudinal direction L, which are set at an angle of 60° to a horizontal plane. The support beams 30 are designed as hollow profile beams. The hollow profile beams are, for example, welded to the first base element 16. It is also conceivable that a screw connection or snap-fit ​​connection is chosen as the type of connection.

[0050] Fig. 1Figure 18 further illustrates that the second base element 18 is also designed as a single-piece support plate. However, in other embodiments, at least one of the two base elements 16, 18 is designed in multiple parts. For example, two support beams 30 are arranged on the second base element 18. These support beams each have a trapezoidal shape in section along the longitudinal direction L, namely, in contrast to the support beams 30 on the first base element 16, the shape of a parallelogram. The two support beams 30 of the second base element 18 are mirror-symmetrical about the central longitudinal axis A. Each of the two support beams 30 has a projection 19 that extends in the longitudinal direction L beyond the side plates 12 and beyond the second base element 18.

[0051] Fig. 2Figure 1 shows, as an example, the support platform 10 in a side view. In particular, the extension 19 is illustrated, which continues across the front of the support platform 10, formed by the second floor element 18 and the longitudinal ends of the side plates 12.

[0052] The design of the side panels 12 is further illustrated. Starting from the area of ​​the first base element 16, the side panels 12 taper in the longitudinal direction L to the second base element 18. The lower edge of the side panels 12 is, for example, positioned lower in the area of ​​the first base element 16 than in the area of ​​the second base element 18. However, the underside 28 lies in the same plane as the underside of the second base element 18. The second base element 18 is correspondingly deeper to compensate for the aforementioned offset of the lower edge of the side panels 12. The side panels 12 have, for example, a recess 35 between the first and second base elements 16, 18.

[0053] Fig. 2Figure 12 further illustrates that the side plates 12 each have a locking lug 37 in the area of ​​the second base element 18. If the support platform 10 is placed, for example, in a pocket wagon (not shown in detail here), whether loaded or unloaded, the locking lug 37 serves in particular as a stop for the support platform 10 against at least part of the pocket wagon. This ensures, in particular, that the support platform 10 cannot slip in the longitudinal direction L, for example, due to impacts and / or acceleration or deceleration of the pocket wagon, to such an extent that it comes into conflict with the bogies of the pocket wagon.

[0054] Fig. 3aFigure 1 illustrates a frontal view of the support platform 10, with the first floor element 16 positioned in the foreground. A portion of the second floor element 18 is visible through the central tunnel 22. It is evident that the support platform 10 forms a W-shape, with the central tunnel 22 forming the flattened central point of the W. On each side, in the transverse direction Q, the second floor element 16 has a transition section 32 chamfered at an angle of approximately 45°. The gripping edges 14 in the area of ​​the first floor element are clearly visible as structures mounted on the side plates 12 and extending outwards at an angle. The stacking hooks 36 in the area of ​​the first floor element 16 are shown, for example, in their operating position.

[0055] Fig. 3bFigure 1 shows an example of a frontal view of the support platform 10, with the second floor element 18 positioned in the foreground. It is evident that diagonal reinforcements 27 are provided at the outer edges in the area of ​​the transition sections 32 for additional stabilization. It is also noticeable that the transition sections 32 have a more rounded chamfer in the area of ​​the second floor element 18.

[0056] Fig. 4a Figure 1 illustrates a longitudinal sectional view of a pocket trolley 42, onto which, for example, a support platform 10 with a schematically indicated semi-trailer 40 was loaded using a gantry crane. The semi-trailer 40 has, for example, three axles at the rear with a corresponding number of wheels 46 and a support winch 47 on each side at the front. The in Fig. 4aThe illustrated platform 10 further features the exemplary special characteristic that, in addition to the locking lug 37, a lug-like auxiliary locking device 39 is provided on each of the side plates 12 in the area of ​​the not clearly visible recess 35. The auxiliary locking device 39 also serves the purpose of preventing the platform 10 from slipping, for example, in the event of an impact on the trolley 42, particularly by striking the intermediate supports 48 shown here. The intermediate supports 48 can also support the side plates 12 in the area of ​​the recess 35.

[0057] How to that in turn Fig. 4b As illustrated, the support platform 10 with the central tunnel 22 is supported here on a central support 44 of the pocket wagon 42. As also Fig. 4bThe wheels 46 are further illustrated as being supported on the base of the pocket trolley 42. Even those wheels which, as not shown in detail here, are arranged in the wheel recesses 20, can rest on the base of the pocket trolley 42 thanks to the central tunnel 22. The transition sections 32 are also shown here with correspondingly inclined side surfaces of the pocket trolley 42. In the connection area between the side plates 12 and the gripping edges 14, the support platform 10 can be shown here, for example, with support lugs 50 formed on the pocket trolley 42.

[0058] The support platform 10 shown here has an exemplary dead weight of only approximately 2450 kg. The dead weight may vary in other embodiments.
