Description

The invention relates to a platform for storing and/or loading semi-trailers, a stack of platforms, and a method for loading semi-trailers.

From the WO 2016/141399 A1 a support device for loading semi-trailers is known. The support device has in particular a support frame with upwardly protruding side parts, which are connected by means of a plurality of cross members as contact surfaces and also by means of at least one support device. In each case, two cross members are spaced apart in such a way that the wheels of the semi-trailer can be placed between them. It is also disclosed that the carrying device can be set up directly on a terminal floor by means of the contact areas.

Next is from the EP 3 623 244 A1 a method for loading a semi-trailer onto a flat car is known. The semi-trailer is driven forwards or backwards directly into a supporting frame by means of a tractor. The supporting frame is then placed on the flat car by means of a lifting device. The supporting frame has longitudinal elements which are connected by means of a plurality of cross members. In this case, two spaced-apart cross members each form pockets between one another for receiving the wheels of one axle in each case. Four crossbeams are provided for three axles of a semi-trailer, with the wheels still being held in the pockets after the supporting frame has been positioned on the flat wagon.

Support devices of the type already known have a high dead weight. They have separate pockets for receiving the wheels for each axle of a semi-trailer, the pockets being formed accordingly by a plurality of cross members.

Accordingly, such carrying devices also have a low level of efficiency, since the maximum loading weight is also reduced in view of the increased dead weight. Finally, known carrying devices are also complicated to handle. In particular, additional means for securing the semi-trailer on the support device are commonly required when it rests on a flat wagon or pocket wagon.

The invention is therefore based on the object of providing a platform that has a low intrinsic weight and is easy and safe to handle and flexible in use.

The invention solves the problem with a platform according to claim 1, a platform stack according to claim 13 and a method according to claim 15. The dependent claims relate to advantageous embodiments.

The platform according to the invention for storing and/or loading semi-trailers has two side elements which extend parallel to one another in a longitudinal direction and are spaced apart from one another in a transverse direction transverse to the longitudinal direction. Within the scope of the invention, the side elements can be designed in particular as beam supports, profile supports, traverses or in particular as support plates.

According to the invention, a plurality of stop elements are arranged on the side elements. Within the scope of the invention, stop elements can be understood to mean connecting means such as gripping edges or the like, which can be brought into operative connection with a stop means in order to lift the platform. The platform can be lifted and loaded accordingly via the stop elements, in particular with a crane or in some other way. The stop elements can be understood both as an integral part of the respective side element and as a part connected separately to the respective side element.

The platform according to the invention also has a first floor element and a second floor element, by means of which the two side elements are connected to one another in the transverse direction. Within the scope of the invention, the floor elements can be designed in one piece with the side elements, or they can be present separately and accordingly be securely connected.

According to the invention, the first floor element also has a wheel well adjacent to one of the side elements and a raised center tunnel between the two wheel wells. Within the scope of the invention, the wheel recesses can be designed as openings or as recesses in the first floor element.

The platform according to the invention has a low dead weight and therefore enables the storage and/or loading of semi-trailers, even with increased loads, in an efficient manner. For this purpose, the platform has a particularly simple structure and achieves the advantages mentioned in particular by accommodating a semi-trailer on only one pair of wheel wells. Thanks to the central tunnel, the platform is also flexibly suitable for being loaded onto pocket wagons in a particularly safe manner.

In particular, the side elements can be designed in such a way that they extend away from the first and second floor elements. In this case, the side elements can preferably, as mentioned above, be in the form of support plates which are elongate in the longitudinal direction and which correspondingly extend at a height away from the first or second floor element.

The center tunnel can be characterized, for example, in that the material thickness of the first floor element in the area of the center tunnel is less than in those areas in which the wheel recesses are formed. Then the first floor element can have a flat surface. However, the first floor element can also be designed in particular in such a way that the center tunnel is designed as a tunnel-like bulge or profiling of the first floor element. In this case, the first floor element can preferably be formed from one or more support plates.

In a section through the first or the second floor element in the transverse direction, the platform can preferably have a bowl-like or trough-like shape. Because of the central tunnel, the first floor element can have an indentation, which can be designed like a tunnel in the longitudinal direction. The platform is preferably axisymmetric formed to a central longitudinal axis. Accordingly, the central tunnel is particularly preferably arranged centrally between the two side elements. If the first floor element is made of a support sheet, for example, as mentioned above, it is possible for the first floor element to be “W”-shaped in the aforementioned sectional view, with the central tunnel forming the central tip of the “W” in a flattened shape in particular. At the outer ends, the first base element can be correspondingly connected to the side elements. The side elements can in turn preferably be connected to the first floor element in such a way that the entire platform is “W”-shaped in the sectional view mentioned. In a sectional view analogously in the transverse direction through the second floor element, the platform can then in turn preferably be configured in a "U" shape. It is also conceivable that the first floor element is formed from, for example, a pair of beam supports or the like, with the beam supports particularly preferably having the central tunnel in the middle between the side elements.

The distance between the side elements of the platform in the transverse direction can be based in particular on the width of the semi-trailer to be accommodated and also on the width of common pocket wagons onto which the platform including the semi-trailer stored thereon can be loaded. The platform is in particular made of steel or a similarly resilient material. The side elements can preferably be made of the same material as the first and the second base element, but can also be made of a different material. This also applies, for example, to the two floor elements one below the other. The two floor elements can preferably be connected to the side elements in a materially bonded manner. 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.

The first floor element and/or the second floor element are more preferably arranged in the longitudinal direction at the end on the side elements. This means that the side elements can terminate with their long-side ends with long-side ends of the first and of the second floor element, viewed in the transverse direction. The side elements therefore each form a final front of the platform, for example with the first and/or the second floor element when viewed in the longitudinal direction. It is particularly conceivable that the second floor element has an extended section, which protrudes beyond a longitudinal end of the side members.

The second floor element can preferably be formed from one or more support plates, which are formed into a preferred configuration. If several carrier plates are provided, the individual plates can be bonded to one another. Particularly preferably, the second floor element can be bent up at its lateral ends towards the side elements, and can thus be connected to the side elements in particular in a materially bonded manner. It is also possible for the second floor element to be essentially planar between the above-mentioned bent-up ends. Furthermore, the second floor element can in particular be designed in such a way that a semi-trailer with its support jacks and/or other supporting structure can be safely parked on it.

The second floor element can preferably have an underside which lies in a common ground plane with the underside of the first floor element in the region of the wheel wells. The underside of the first floor element in the area of the central tunnel is at a distance from the ground level in terms of height.

With the ground level of the floor elements, it is possible, for example, to park the platform directly on a surface, for example a terminal corridor. It is then also possible to drive a semi-trailer directly onto the platform using a towing vehicle, ie without an additional ramp. If the semi-trailer has three axles at the rear, the wheels on the middle axle are preferably accommodated in the wheel recesses. The wheels of the front axle can each be supported on a front outer side of the corresponding wheel recess in the region of their running surface pointing backwards towards the central axle. The wheels of the rear axle, that is to say the rear axle, can in turn each be supported on a rear outer side of the corresponding wheel recess with their running surface pointing forward to the central axle. The rear of the semi-trailer can therefore, for example, overhang backwards over the platform. If the platform rests on a terminal floor with its base level, a semi-trailer loaded on the platform can be parked with the treads of its wheels on the terminal floor, while it is further supported with its support jacks and/or other supporting structure on the second floor element. The wheel recesses therefore preferably have such a dimension that the wheel wells only come into contact with the running surfaces of the wheels when loading, ie when raising the platform, as mentioned above. When the platform is raised, the wheels can preferably be accommodated in the wheel wells in a form-fitting manner. If the wheel recesses are in particular rectangular, the wheel recesses can each have a width in the transverse direction in the range from 500 mm to 800 mm, preferably 550 mm to 700 mm, particularly preferably 625 mm to 675 mm. The wheel recesses can also each have a length in the longitudinal direction in the range from 550 mm to 850 mm, preferably 600 mm to 750 mm, particularly preferably 675 mm to 725 mm. It is thus possible, for example, despite the efficient design of the wheel recesses, to store and/or load semi-trailers with dual tires using the platform.

In particular, when loading a semi-trailer, the wheel recesses can be loaded with large weight forces by the wheels of an axle of the semi-trailer that are accommodated therein. It can therefore be advantageous if the load of the wheels in the wheel wells can be dissipated on all sides directly to the first floor element or to the corresponding side element. According to a preferred embodiment, the two wheel recesses are therefore designed as recesses in the first floor element, which are each delimited in the longitudinal direction by a pair of transverse struts of the first floor element running in the transverse direction, and in the transverse direction on the outside by one of the side elements and on the inside by the center tunnel.

As mentioned above, the center tunnel can advantageously be designed to be able to be safely placed on a center support of a pocket wagon. The first floor element can then rest laterally on this center support in the area of the wheel wells. According to a further preferred embodiment, the first floor element therefore has an underside which in the area of the center tunnel is spaced apart in terms of height by a tunnel height from the underside in the area of the wheel recesses.

Similar to the aforementioned case of a platform parked with a semi-trailer on a terminal corridor, for example, it can be advantageous if the tunnel height is designed in such a way that a semi-trailer loaded onto a pocket wagon using the platform can support itself with the treads of its wheels on the bottom of the pocket wagon. This also has the advantage that the platform does not exceed the loading height of the semi-trailer raised on the pocket wagon. According to a further preferred embodiment, the central tunnel therefore has a tunnel height in a range from 3 cm to 12 cm, preferably 4 cm to 10 cm, very particularly preferably 5 cm to 8 cm. For example, the platform can be viewed as a dead entity. This means that the platform on the terminal corridor and/or on the pocket wagon, for example, has neither an influence on the load height of the corresponding semi-trailer nor a negative influence on load securing. In particular, no additional means of securing loads on a pocket wagon are required, for example because of the use of the platform.

It is also advantageous for flexible positioning of the platform on a pocket wagon if the center tunnel has lateral play on the aforementioned center support of the corresponding pocket wagon. According to a further preferred embodiment, the central tunnel therefore has a width, measured in the transverse direction, in a range from 80 cm to 120 cm, preferably 85 cm to 110 cm, particularly preferably 90 cm to 100 cm.

It can also be 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 an upper side which lies in one plane. It can be particularly advantageous to construct the first floor element in the area of the wheel wells up to the level of the upper side of the first floor element in the area of the center tunnel. According to a further preferred embodiment, attachment elements are therefore arranged on the first floor element and/or on the second floor element.

If the second floor element has, for example, an upper side which lies in one plane with the upper side of the first floor element in the area of the wheel wells, attachment elements can then advantageously also be arranged on the upper side of the second floor element. The attachment elements can, for example, be in the form of beam supports, hollow profile supports or the like. For each wheel recess on the first floor element, preferably two such attachment elements can be provided on the corresponding cross braces, which delimit the wheel recesses in the longitudinal direction. The upper sides of the attachment elements, at least on the first floor element, are particularly preferably in one plane with the upper side of the first floor element in the area of the central tunnel. In the same level you can continue if necessary preferably also the tops of the attachment elements can be arranged on the second base element. The attachment elements can be formed on the platform, preferably in a trapezoidal section along the longitudinal direction. However, it is particularly possible that the attachment elements of the second floor element have a different trapezoidal shape than the attachment elements of the first floor element, in particular in the form of a parallelogram. Trapezoidal add-on elements make it easier, for example, to load the semi-trailer onto the platform without an additional ramp. At the same time, it can help to protect the wheels, in particular the tires of the semi-trailer during loading.

It can also be advantageous if semi-trailers of different designs can be supported on the second floor element in a safe and flexible manner with their support jacks and/or correspondingly individual additional support structure. According to a further preferred embodiment, the attachment elements of the second floor element therefore have recesses, in particular elongated holes, for the passage of supporting elements of the semi-trailer. On the one hand, the support elements can be flexibly positioned along the width. On the other hand, it is also possible to be able to balance the height of the supporting elements more easily. The support elements can in particular be passed through the top element of the second floor element and supported on the upper side of the second floor element. It is also possible that the second base element also has recesses analogous to the top element. Supporting elements can then also be pushed through the second floor element, so that the semi-trailer, for example in the pocket wagon, can then also be additionally supported on the pocket wagon with its own supporting structure.

For precise and safe positioning of the platform in a pocket wagon, it can also be advantageous if the transition from the first and/or the second floor element to the side elements is continuous, i.e. in particular not, for example, abruptly formed at right angles. For example, right-angled transitions are subject to increased mechanical and abrasive stress, so that they can also be more susceptible to mechanical failure or damage. A steady transition can accordingly also further increase the durability of the platform. According to a further preferred embodiment, the side elements and the first and/or the second base element therefore each go by means of a rounded, but at least by means of a chamfered transition section into each other. It is conceivable that the side elements and the two base elements are designed in one piece, as mentioned above, for example from a carrier plate. In this case, the transition section can be easily folded out into the desired configuration when the carrier plate is formed. However, it is also possible for the side elements and the two base elements to be present separately and for at least one of the elements to have a corresponding transition section. The separate side or base elements can then be connected to one another in a materially bonded manner at the transition section.

If the side elements are designed as support plates, as described above, it can be advantageous to design them in the manner of a truss, in particular to further reduce the weight of the platform. According to a further preferred embodiment, the side elements therefore have recesses. The recesses can be designed, in particular in a statically advantageous manner, as circular, pill-shaped and/or oval holes. It is also conceivable to provide other shapes for the recesses, for example polygons. These preferably have rounded tips, which in turn can increase the durability of the platform.

In order to be able to use the platform even more efficiently and flexibly, it can also be advantageous to be able to stack platforms that are temporarily unused on top of and/or inside one another to save space. 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, in particular gripping edges, of the platform. At least one or more stacking hooks can preferably be provided per stop element. For better load distribution and stability, the stop elements can be arranged in the area of the two floor elements in relation to the longitudinal direction. Two stop elements, in particular gripping edges, can preferably be provided for each side element.

The stacking hooks preferably point inwards starting from the side elements, ie in the direction of the central longitudinal axis. It is then possible for a platform to rest on at least one stacking hook of another platform with part of its underside of the first floor element and with part of its underside of the second floor element is supported. Furthermore, it is also possible for a platform to be supported at the aforementioned transition sections on stacking hooks of another platform in the manner described above. The second platform stacked on a first platform can be arranged with at least part of its two base elements between the side elements of the first platform.

It can also be advantageous to design the stacking hooks in such a way that damage to loaded semi-trailers can be avoided. It can be taken into account that the platform will not be increased in width because of the stacking hooks. According to a further preferred embodiment, the stacking hooks are therefore designed to be pivotable between a use position and a rest position. For this purpose, the stacking hooks can be mounted in particular in an articulated manner on the stop elements of the side elements. In the rest position, the stacking hooks can in particular bear against an outside of the respective stop elements, so that there is no risk of collision with a semi-trailer to be loaded. It is also conceivable to swing the stacking hooks up into another rest position. In the use position, the stacking hooks point inwards, as mentioned above. In particular, the stacking hooks can be pivoted manually between the rest position and the use position. It is also conceivable to automate this. It is also conceivable that, for example, the stacking hooks on a side element are in an operative connection with one another and can then in particular be swiveled together manually.

It can also be advantageous if the stacking hooks can be secured so that they do not arbitrarily swing out into the use position, for example. According to a further preferred embodiment, the stacking hooks are therefore also assigned securing means for locking the stacking hooks in the rest position. For this purpose, the stacking hooks can be locked to the respective stop elements or side elements, for example by means of safety pins or similar. It is also conceivable that the stacking hooks can be attached to the stop element in a latching manner. Finally, it is possible for receiving elements to be provided on the stop elements, in which the stacking hooks can in turn be locked.

The invention further relates to a platform stack. Depending on the implementation, the above features and definitions, for example, may also apply here to the platforms mentioned below in this regard.

The platform stack according to the invention has 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 one another in a transverse direction by means of a plurality of floor elements.

According to the invention, a plurality of stacking hooks are formed on the side elements of at least the first platform, with the second platform resting with undersides of the side elements and/or the base elements on the stacking hooks of the first platform.

As explained above, it is possible for the stacking hooks to be arranged on stop elements, in particular gripping edges, of the respective side elements such that they can pivot between a rest position and a use position. The stacking hooks can also be designed to be lockable in the rest position.

According to a preferred embodiment, the first and/or the second platform have a first floor element, which has a wheel well adjacent to one of the side elements and a raised central tunnel between the two wheel wells.

Finally, the invention relates to a method for loading semi-trailers onto pocket wagons using a platform, having two side elements which extend in the longitudinal direction and have stop elements and which are connected to one another in a transverse direction by means of a first and a second floor element, with the first floor element each adjoining one of the side elements has a wheel well and between the two wheel wells a raised center tunnel.

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. The wheels of an axle of Semi-trailers are parked in the wheel wells, with the wheels preferably resting on the ground under the platform, so that the semi-trailer can independently support itself with the treads of its wheels.

In a second step of the method according to the invention, the platform is then raised at the stop elements. If the stop elements are designed as gripping edges, for example, the lifting can be done, for example, by means of a crane, in particular a gantry crane, or with a mobile device. When lifting, in particular those wheels of the semi-trailer that were previously parked in the wheel wells come into contact with boundary surfaces of the wheel wells. In the case of a semi-trailer with three rear axles, this can be the wheels on the middle axle in particular.

In a third step of the method according to the invention, the platform is set down on the pocket wagon in such a way that the platform with the central tunnel is parked on a center support of the pocket wagon and the semi-trailer with its tires is placed independently on a base of the pocket wagon. The semi-trailer can also be supported on the platform, in particular on the second floor element, for example with its support jacks and/or further support structure. The king pin of the semi-trailer can in turn be supported, for example, on a trestle of the pocket wagon.

Features and definitions that were previously made for the platform or the platform stack can also be transferred to the method according to the invention, for example.

1 shows an example of a support platform 10 consisting of two side plates 12 which extend longitudinally L and which are cross-connected in the transverse direction Q by means of a first base element 16 and a second base element 18 . The support platform 10 is made entirely of steel, for example. The side plates 12 and the two floor elements 16, 18 are each formed from support plates, which have been correspondingly formed. The side plates 12 are welded to the two floor elements 16, 18 in the area of a transition section 32, which is not shown in detail here.

The side plates 12 have recesses 34 in particular to reduce weight. The recesses 34 are shaped differently, here for example circular, pill-shaped, oval or triangular. The triangular recesses 34 have rounded tips.

Gripping edges 14 are formed on the side plates 12 in the area of the two floor elements 16 , 18 in relation 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, which is also not shown in detail here. A stacking hook 36 is also arranged on each of the gripping edges 14 with a securing means not shown in detail here. The stacking hooks 36 can be pivoted between a use position and a rest position. For this purpose, the stacking hooks 36 are mounted on the gripping edges 14 in a correspondingly articulated manner. they are in 1 for example, the stacking hooks 36 in the area of the second floor element 18 are in the use position and the stacking hooks 36 in the area of the first floor element 16 are in the rest position. The pivoting of the stacking hooks 36 takes place here, for example, in a horizontal plane. In the rest position, the stacking hooks 36 are here, for example, each in contact with an outer side of the corresponding gripping edges 14.

How 1 further illustrated is the first floor element 16 here as a one-piece carrier plate educated. Two continuous wheel wells 20 are formed in the first floor element 16 adjacent to the respective side panel 12 . In the longitudinal direction L, the wheel wells 20 border on both sides of the cross braces 24 of the first floor element 16 . In the transverse direction Q, the wheel wells 20 are each bounded on the outside by a side panel 12 and on the inside by a center tunnel 22 . The wheel wells 20 here 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 m.

The first floor element 16 has an underside 28 which, in the area of the center tunnel 22 , is designed to be higher than the underside 28 in the area of the wheel wells 20 . The difference in height is characterized here in particular by a tunnel height H, which is 61 mm here, for example. The central tunnel 22 here, for example, also has a tunnel width B of 930 mm, viewed in the transverse direction. The underside 28 in the area of the wheel wells 20 is in a horizontal plane here.

1 12 further illustrates that the center tunnel 22 has an upper side which lies in a horizontal plane with upper sides of top supports 30 , the top supports 30 being arranged on the cross braces 24 of the first floor element 16 . In addition, two cover plates are arranged on the upper side of the central tunnel 22, which act in particular to secure the attachment supports 30. The attachment supports 30 each have a trapezoidal shape in section in the longitudinal direction L, for example. In relation to the longitudinal direction L, the attachment supports 30 each have oblique outer sides, which here are set at an angle of 60° with respect to a horizontal plane. The attachment carriers 30 are designed here as hollow profile carriers. The hollow profile supports are, for example, welded to the first floor element 16 . It is also conceivable that a screw or snap-in connection is selected as the type of connection.

1 further illustrates that the second floor element 18 is also designed as a one-piece support plate. In other embodiments, however, it is possible for at least one of the two floor elements 16, 18 to be designed in several parts. On the second floor element 18, for example, two top supports 30 are arranged here. These each have a trapezoidal shape in section along the longitudinal direction L, namely here in contrast to the top supports 30 on the first floor element 16 the shape of a parallelogram. The two top supports 30 of the second floor element 18 are mirror-symmetrical formed to the central longitudinal axis A. The two attachment supports 30 each have an extension 19 which protrudes in the longitudinal direction L beyond the side plates 12 and beyond the second floor element 18 .

2 shows an example of the support platform 10 in a side view. Here, in particular, the extension 19 is illustrated, which continues over the front of the support platform 10, which is formed by the second floor element 18 and the longitudinal ends of the side plates 12.

The configuration of the side plates 12 is also illustrated. Starting from the area of the first floor element 16, the side plates 12 taper in the longitudinal direction L as far as the second floor element 18. The lower edge of the side plates 12 is arranged lower here, for example in the area of the first floor element 16 than in the area of the second floor element 18. The underside 28 is located however, in a plane with an underside of the second floor element 18. The second floor element 18 is designed to be correspondingly deeper in order to compensate for the aforementioned offset of the lower edge of the side plates 12. The side plates 12 have a groove 35 here, for example between the first and the second floor element 16 , 18 .

2 also illustrates that the side plates 12 each have a securing lug 37 in the area of the second floor element 18 . If the carrying platform 10 is loaded or unloaded, for example in a pocket wagon not shown here, the securing lug 37 serves in particular as a stop for the carrying platform 10 against at least part of the pocket wagon. It can thus be ensured in particular that the support platform 10 cannot slip in the longitudinal direction L, e.g. due to impacts and/or due to acceleration or braking of the pocket wagon, to such an extent that it comes into conflict with the bogies of the pocket wagon.

Figure 3a illustrates a front view of the support platform 10, the first floor element 16 being arranged in the foreground of the image plane. A part of the second floor element 18 can also be seen through the center tunnel 22 . It is clear that the support platform 10 forms a W-shape here, with the center tunnel 22 being recognizable in a flattened manner as the middle tip of the W. On the sides in relation to the transverse direction Q, the second floor element 16 has a transition section 32 that is chamfered at an angle of approximately 45°. The gripping edges 14 in the area of the first floor element can be seen here wider than superstructures placed on the side plates 12 and extending outwards at an angle. The stacking hooks 36 in the area of the first base element 16 are here, for example, in the use position.

Figure 3b shows an example of a front view of the support platform 10, the second floor element 18 being arranged in the front image plane. It becomes clear that diagonal reinforcements 27 are provided here on the outer edges in the area of the transition sections 32 for additional stabilization. It is also noticeable that the transition sections 32 in the area of the second floor element 18 have a more rounded chamfer.

Figure 4a 1 illustrates a pocket wagon 42 in a sectional view in the longitudinal direction, onto which a support platform 10 with a semi-trailer 40 indicated schematically has been loaded, for example with 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 both sides in the front. In the Figure 4a The platform 10 shown here also has the exemplary special feature that a nose-like additional safety device 39 is provided on the side plates 12 in addition to the safety nose 37 in the area of the recess 35 that is not clearly visible. The additional safety device 39 also serves the purpose, for example in the event of an impulse on the pocket wagon 42, to prevent the platform 10 from slipping, in particular by hitting the intermediate supports 48 shown here. The intermediate supports 48 can also support the side plates 12 in the area of the groove 35 .

How about that again Figure 4b illustrated, here the support platform 10 with the center tunnel 22 is supported on a center support 44 of the pocket wagon 42 . As well as Figure 4b further illustrated, the wheels 46 are supported on the bottom of the pocket wagon 42 . Thanks to the center tunnel 22, those wheels which are arranged in the wheel wells 20, as is not shown in detail here, can also rest on the floor of the pocket wagon 42. The transition sections 32 are here also in contact with correspondingly sloping side faces of the pocket wagon 42. In the connection area between the side plates 12 and the gripping edges 14 , the support platform 10 can be located here, for example, with support lugs 50 formed on the pocket wagon 42 .

The support platform 10 has a dead weight of only approx. 2450 kg here, for example. The dead weight may differ in other embodiments. A different material, a different material thickness of the support plates, for example, and/or the design of the recesses can in particular have an effect on a deviating intrinsic weight. <b>Reference List</b> 10 support platform B tunnel width 12 Page sheet H tunnel height 14 gripping edge L longitudinal direction 16 first floor element Q transverse direction 18 second floor element 19 extension 20 wheel well 22 central tunnel 24 cross brace 26 Long hole 27 diagonal reinforcements 28 Underside of the first floor element 30 attachment carrier 32 transition section 34 recess 35 groove 36 stacking hook 37 safety nose 38 collateral 39 additional security 40 semi-trailer 42 pocket wagon 44 center support 46 wheel 47 landing gear 48 intermediate support 50 support lugs A longitudinal central axis
