FREIGHT WAGONS FOR TRANSPORTING CARGO

Description

[0001] The invention relates to a freight wagon for transporting cargo and a trough for such a freight wagon.

[0002] Rail-bound freight wagons for transporting craneable or non-craneable cargo, especially so-called pocket wagons, are widely known. Such freight wagons are typically designed and equipped for transporting container-shaped cargo as well as semi-trailers. In practice, (insert) troughs are frequently used, particularly for transporting semi-trailers. These troughs, along with the semi-trailer mounted and secured to them, are inserted into a pocket within the freight wagon. This pocket is defined by the wagon's longitudinal beams, which extend between a head section at the front end of the wagon and an end section at the rear. Within this pocket, defined by the two opposing longitudinal beams, a support structure is typically provided for the inserted trough.This support structure is formed, for example, by cross braces connecting the two longitudinal beams and / or at least one additional longitudinal brace running centrally on the freight wagon, in order to position the tub as intended and support it on the freight wagon.

[0003] Such freight wagons are known, for example, from WO 2016 / 141399 A1, DE 10 2006 012208 A1, DE 41 12 995 A1, EP 1 712 444 B1 and EP 0 619 211 B1.

[0004] The freight wagons with integrated cargo troughs that have been developed and used in practice to date are generally relatively inflexible and / or only conditionally economical, as container transport with such freight wagons is usually only possible to a limited extent or only if the trough remains at a loading station. If the trough remains at the loading station, however, additional storage space must be reserved there indefinitely, since other uses or transport of the trough without the associated freight wagon are not possible.

[0005] Recently, underloading systems for freight wagons have been proposed, allowing a semi-trailer truck to drive directly onto a freight wagon with its cargo. Cargobeamer AG, for example, offers such a system with specially designed freight wagons. In this system, each freight wagon has a laterally extendable trough into which a semi-trailer truck can drive. However, the freight wagons used in this system are technically complex and comparatively expensive. The same applies to the special loading systems required at a Cargobeamer loading station.

[0006] There is therefore a need for ways to further make rail-bound transport of cargo more flexible and cost-effective, as well as to facilitate the loading process of cargo onto rail.

[0007] Against this background, a freight wagon according to claim 1 is proposed according to the invention.

[0008] According to the invention, a freight wagon with a tub positioned in its loading position within the wagon's pocket can be transported along with the wagon. Simultaneously, container-shaped cargo can be transported without this cargo needing to rest on the tub's loading surface. The freight wagon is equipped with fastening elements to transport container-shaped cargo without requiring it to rest on the tub's loading surface. At the same time, the tub is positioned on the freight wagon in a loading position that does not restrict the loading and unloading of container-shaped cargo and allows the container-shaped cargo to be easily positioned and secured above the tub's loading surface as intended.Thus, the transport of containers and the transport of semi-trailers are possible independently of each other with such a freight wagon, and therefore optionally, without having to remove the trough from the freight wagon, provided that at least one container is to be transported. It is therefore possible to transport at least one container with the freight wagon from a first loading station to a second loading station in or above the pocket in which the trough is inserted, and then, at the second loading station, to load a semi-trailer using the trough and transport it to a third loading station after the at least one container has been unloaded at the second loading station.In one version, the freight wagon is designed, for example, to transport a 45-foot container, which rests on the loading platform of the head section and the loading platform of the end section and extends over the tub loading platform of the tub inserted into the pocket in the area of ​​the longitudinal beams.

[0009] The tub is equipped with at least one connecting element, designed with a connecting opening, for connection to a fastening element. This connecting element is positively locked to the fastening element via this opening when the tub is in its loading position. The positive-locking connection between the fastening element and the tub, via a connecting element specifically designed for this purpose, facilitates the intended positioning of the tub and also ensures secure locking of the tub to the longitudinal beams.

[0010] Alternatively or additionally, the tub can be suspended from the longitudinal beams' fastening elements in the loading position. Suspending the tub can be achieved, for example, via at least one connecting element on the tub that forms a connecting opening. For instance, the tub may have at least one tab-shaped connecting element that engages with an inwardly projecting fastening element of the freight car, such as a pin-shaped one, when the tub is in the loading position. The tub can thus be easily inserted into the pocket from above and suspended from the longitudinal beams' fastening elements.

[0011] In the embodiment described above, the freight wagon pocket can be designed as a continuous recess, i.e., without cross braces connecting the two longitudinal beams between the head and end pieces, and without an additional longitudinal brace connecting the head and end pieces and running within the pocket. In such an embodiment, there is therefore no supporting structure on the freight wagon, apart from the longitudinal beams, to support the inserted tub. Specifically, the tub, when in the loading position and possibly suspended from the longitudinal beams, does not rest on a support structure connecting the two longitudinal beams.

[0012] The freight wagon can be built relatively easily and used with great flexibility.

[0013] In one embodiment, fastening elements are provided on the longitudinal beams, defining a transport position for container-shaped cargo on the freight wagon. With the tub in the loading position, the container-shaped cargo extends above the tub's loading surface, covering at least a portion of it. Thus, fastening elements, for example, in the form of mounting pins, are provided on the longitudinal beams. These enable the intended positioning and fixation of container-shaped cargo on the freight wagon, keeping it above the tub's loading surface. In this way—in accordance with the first aspect of the proposed solution—the tub in the loading position does not need to be designed for container transport and can be easily carried on the freight wagon during container transport.

[0014] In a possible further development, the fastening elements for container-shaped cargo define at least two different transport positions, in which the container-shaped cargo extends above the loading platform and across at least a portion of it. In this embodiment, for example, fastening elements for at least two different types of ISO containers can be provided on the longitudinal beams of the freight wagon. The fastening elements for a first type of container define a first transport position, which differs from a second transport position defined by the same or different fastening elements on the longitudinal beams for a different, second type of container. For example, fastening elements for different types of containers can be provided at different heights on the longitudinal beams.For example, the first set of fasteners for one type of container are located closer to the top edge of each longitudinal beam, while the fasteners for another type of container are located lower on the longitudinal beams and within the pocket. For example, different and differently positioned fasteners are provided on the longitudinal beams for positioning 20-foot, 40-foot, and 45-foot containers.

[0015] In principle, at least one of the fastening elements for container-shaped cargo can be adjustable along a longitudinal beam and / or completely removable from the longitudinal beam. An adjustable fastening element thus allows for the specification of different fastening points along a longitudinal beam by allowing the fastening element to be adjusted, in particular moved, along the longitudinal beam. Alternatively or additionally, a fastening element that is completely removable from the longitudinal beam also allows for the variable specification of a fastening point. A completely removable fastening element can, for example, be detachably connected to the respective longitudinal beam so that the fastening element can be removed from the respective longitudinal beam if necessary. The position of individual fastening points can, for example, depend on the size of the container to be transported.Both an adjustable and a completely removable fastening element can also have the advantage that the respective fastening element can be positioned on or in the pocket of the freight wagon only when needed to hold and secure container-shaped cargo.

[0016] In one embodiment, at least one of the fastening elements for container-shaped cargo is pivotally mounted on the longitudinal beam. This means that the at least one fastening element is adjustable about a defined pivot axis, as determined by the design. For example, the at least one fastening element pivotally mounted on the longitudinal beam can pivot between a non-use position and a use position. In its non-use position, the fastening element is located outside the pocket, and in its use position, it is located inside the pocket. In its non-use position, such a fastening element is thus pivoted out of the pocket, thereby opening the pocket for loading and unloading cargo with or without a container.

[0017] In one embodiment, at least one of the fastening elements provided on the longitudinal beams for defining a transport position for container-shaped cargo can also define the functional position for the trough on the freight wagon's pocket. In this configuration, the trough's loading surface is at least level with the loading surface of the end section (and possibly also with the loading surface of the end section of the freight wagon), thus defining a continuous loading surface with the end section's loading surface. Such a fastening element therefore fulfills a dual function on the freight wagon. On the one hand, it is designed and intended for the proper holding and securing of container-shaped cargo on or in the pocket.On the other hand, the same fastening element is also designed and intended to hold the trough in a functional position in addition to the loading position. Such a modified freight wagon thus enables additional flexibility in the rail transport of a wide variety of cargo through a comparatively small number of fastening elements and the freight wagon equipped with a trough.

[0018] In one embodiment, the freight wagon equipped with the tub can optionally transport at least one 20-foot container, at least one 40-foot container, at least one 45-foot container, at least one semi-trailer, and / or at least two tractor units. In a further development, a combination of different fastening elements and the tub attached to the longitudinal beams allows for the optional transport of all the aforementioned cargo. Thus, one and the same freight wagon (with the tub attached to the longitudinal beams) can optionally transport either at least one 20-foot container, at least one 40-foot container, at least one 45-foot container, at least one semi-trailer, or at least two tractor units.

[0019] In another embodiment, a trough for a freight wagon for transporting (craneable or non-craneable) cargo is proposed, in which the trough includes a ramp assembly with at least one ramp for driving a semi-trailer truck into the trough and in which the ramp assembly has two different ramp positions on the trough.

[0020] A tractor unit can drive into the loading platform via at least one ramp to park a semi-trailer on the platform's loading area (which may be continuous or only partially present). The platform is typically placed on the floor at a loading station and then positioned with the semi-trailer in a compartment of the freight wagon. Such a ramp is usually a separate component, kept at a loading station, i.e., a terminal, independently of the loading platform itself. In practice, the ramp is positioned according to the tractor unit's track width and, if necessary, fixed to the platform on the floor. After the semi-trailer is parked in the platform, the ramp is removed. Handling and transporting such ramps usually complicates the loading process.

[0021] By predefining at least two different ramp positions on a proposed tray for the ramp assembly—one for transporting a semi-trailer and the other for transporting a tractor unit—handling and transporting at least one ramp of the assembly are significantly simplified. Depending on whether a semi-trailer or a tractor unit is to be transported and loaded onto a freight wagon using the tray, the ramp assembly is positioned in either the first or second predefinite ramp position on the tray.

[0022] In this context, it is of course possible to use such a tub with ramp assembly in a freight wagon according to the aforementioned design variants of the first and / or second aspect of the proposed solution. In particular, the ramp assembly can also be positioned and fixed to the tub as intended when the tub is in a loading position in the pocket of the freight wagon, but the freight wagon is transporting container-shaped cargo that is not held against the tub.

[0023] Regardless of the above, one embodiment provides that the at least one ramp of the ramp assembly, in the first ramp position, is located on the tub in a position that is offset laterally and / or parallel to the position of the at least one ramp in the second ramp position with respect to one of the ramp's directions of extension. In the first ramp position, the ramp is thus offset laterally and / or parallel to, for example, a position for transporting a tractor unit with respect to the tractor unit's entry direction. A lateral offset can be provided, for example, to accommodate different track widths. A parallel offset can also be due, for example, to the use of the at least one ramp as a transport surface on which the tractor unit remains at least partially positioned even after the tub has been loaded onto the freight wagon.Thus, a ramp that is offset parallel to the first ramp position in the second ramp position can project further beyond the front edge of the tub than in the first ramp position, thereby providing a transport area for a semi-trailer truck that extends beyond the edge of the tub.

[0024] In one embodiment, at least one ramp is pivotably mounted on the tub, at least in the second ramp position intended for transporting a semi-trailer truck. This allows the ramp to pivot upwards, for example, when the tub is inserted into the freight wagon's pocket, in order to hold and transport a semi-trailer truck positioned against the tub and standing on the at least one ramp in a tilted position against the freight wagon.

[0025] Alternatively or additionally, the ramp assembly can comprise at least one pair of ramps and at least one ramp extension. The at least one ramp extension can be positioned as intended in the first ramp position, intended for transporting a semi-trailer, between the two ramps of the ramp pair, while the at least one ramp extension in the second ramp position, intended for transporting a tractor unit, can be connected to or is connected to one of the ramps of the ramp pair to extend the respective ramp. The ramp extension can be stored compactly against the trough in the first ramp position. If required, the ramp extension in the second ramp position can be connected to one of the ramps, for example, to use it for driving in or transporting the tractor unit.With just a few combinable components of a ramp assembly, a relatively simple adaptation to different loading scenarios is possible on a tub, without having to provide different tubs or ramp assemblies.

[0026] In principle, at least one ramp extension can be detachably fixed to at least one ramp of the pair in the first ramp position. The ramp extension is thus secured to the platform in the first ramp position intended for transporting a semi-trailer. However, the fixation can be released if necessary, making the ramp extension usable in the second ramp position. For example, the ramp extension is fixed by means of at least one fixing element, such as a fixing bolt or pin, which extends transversely to one direction of the ramp's length.

[0027] In a possible further development, the ramp assembly comprises two pairs of ramps and / or two ramp extensions. Using two pairs of ramps and predefined, different ramp positions on the tub facilitates the entry of a semi-trailer into the tub from different directions without requiring the ramps to be moved from one end of the tub to the other or the tub to be rotated 180°. This also simplifies the transport of two tractor units on one tub by allowing them to enter from opposite directions using both pairs of ramps. In this way, the tractor units, with their cabs facing each other, can each have their rear wheels positioned on the ramps of one pair of ramps, which project beyond the tub's loading area on both sides.

[0030] The attached Figures 1 to 27 The figures show, in different views and configurations, a freight wagon designed as a double pocket wagon 1, which is characterized by its exceptional flexibility in terms of transporting a wide variety of cargo. The double pocket wagon 1 of the Figures 1 to 27Both craneable and non-craneable cargo, especially semi-trailers, tractor units, and ISO containers of various sizes, can be transported. The double pocket wagon 1, designed for intermodal freight transport, offers maximum flexibility with regard to the types of cargo to be transported and loaded.

[0031] As seen particularly in the overall view of the Figures 1 to 7B As shown, the double pocket trolley 1 has two articulated pocket trolleys 1A and 1B. The pocket trolleys are fundamentally identical in design, so that features described below for one of the pocket trolleys 1A or 1B also apply to the other pocket trolley 1B or 1A.

[0032] The double pocket wagon 1 has a total length I of approximately 34 m and complies with the requirements of the G1 clearance gauge for international freight transport. For rail transport, the double pocket wagon 1 comprises three bogies DG1, DG2, and DG3. One bogie DG1 or DG3 is located at one end piece 12 of a pocket wagon 1A or 1B, while the other bogie DG2 is positioned centrally at the articulated joint G between the two pocket wagons 1A and 1B on the double pocket wagon 1. At the articulated joint G, the two pocket wagons 1A and 1B are coupled to each other via an end piece 13.

[0033] A head section 12 and an end section 13 of a pocket wagon 1A or 1B each form a loading platform 120 or 130 on the double pocket wagon 1 shown. In the area of ​​a first loading platform 120 of the head section 12, a pin receptacle 121 for a kingpin of a semi-trailer is provided. Between a head section 12 and an end section 13, two longitudinal beams 11.1 and 11.2 extend opposite each other, connecting the head section 12 and the end section 13. A pocket 10 with a length of at least 9 m, and in particular at least 10 m, is defined between the longitudinal beams 11.1 and 11.2. This pocket 10 is bounded only by the two longitudinal beams 11.1 and 11.2 and the head section 12 and the end section 13 of a pocket wagon 1A or 1B. Therefore, there is no further connection between the longitudinal beams 11.1 and 11.2.2 or the head piece 12 and the end piece 13 connecting each other, a support structure is provided. The pocket 10 is thus designed merely as a continuous recess without additional transverse or longitudinal stiffening support structures and is enclosed on its circumference by a frame-like structure consisting of the head piece 12, the two longitudinal beams 11.1 and 11.2 and the end piece 13.

[0034] Each pocket 10 of a pocket trolley 1A or 1B of the illustrated double pocket trolley 1 contains a removable (insert) tray 2. A tray 2 is suspended from the two opposing longitudinal beams 11.1 and 11.2 by means of fastening elements designed as suspension pins 110a and 110b. This is particularly evident in the Figure 1 , 2 , 2A to 2B and 3As illustrated, a tub 2 has a flat loading platform 20 on which, for example, a semi-trailer or a tractor unit can be positioned. Along the lateral edges of this loading platform 20, the tub 2 forms connecting elements in the form of four mounting lugs 21a to 21d. Two mounting lugs 21a / 21b or 21c / 21d, each formed on one longitudinal side of the tub 2, are designed and intended for attachment to one of the longitudinal beams 11.1, 11.2.

[0035] Here, each individual suspension tab 21a to 21d forms a connecting opening 210 into which, when the tub 2 is suspended, for example by means of a reach stacker or a gantry crane, a suspension pin 110a or 110b formed on the longitudinal beam 11.1 or 11.2 can engage in a form-fitting manner. As can be seen, for example, in the enlarged illustrations of the Figures 2A and 2BAs can be seen, each suspension pin 110a or 110b forms a cylindrical body 1100 with a head 1101 at its end, projecting inwards from the respective longitudinal beam 11.1, 11.2. A suspension tab 21a to 21d of the tub 2 is hooked onto the body 1100 of the suspension pin 110a or 110b via its connecting opening 210, so that an upper edge of the respective suspension tab 21a to 21d is located between an inner surface of the respective longitudinal beam 11.1 and 11.2 and the head 1101 of the associated suspension pin 110a or 110b when the tub 2 is inserted into a pocket 10 as intended.

[0036] For loading the tub 2, and in particular for inserting it into a pocket 10 or removing a tub 2 from the pocket 10, transport platforms 211 with through-openings are provided at one upper end of each mounting tab 21a to 21d. Conventional loading systems, such as a reach stacker or gantry crane, can engage in the through-openings of the transport platforms 211 to remove a tub 2 from the respective pocket 10 or to insert it into the pocket 2.

[0037] If the tub 2 is properly suspended from the longitudinal beams 11.1 and 11.2 of the double pocket wagon 1, the loading surface 20 of tub 2 is lower than the loading surfaces 120 and 130 of the head piece 12 and the end piece 13. This fact is used here to enable the transport of container-shaped cargo without having to use tub 2. Container-shaped cargo can thus be transported with the double pocket wagon 1. Figures 1 to 27Tub 2 can be transported independently of tub 2. Tub 2 can therefore remain suspended from the longitudinal beams 11.1 and 11.2 in the respective pocket 10, even if no cargo is being transported in tub 2.

[0038] Each pocket trolley 1A, 1B of the double pocket trolley 1 has additional fastening elements in the form of mounting pins 300 and 40 in the area of ​​one pocket 10, to which ISO containers of different types and sizes can be securely fixed without having to remove the tub 2 or position it in pocket 10. Each pocket trolley 1A or 1B is provided with several different mounting pins 300 and 40 in the area of ​​the longitudinal beams 11.1 and 11.2 to enable the transport of container-shaped cargo of different sizes on and in pocket 10.

[0039] As particularly evident from the Figures 4 , 5 , 5A to 5B , 6A to 6B and 7A to 7BAs illustrated in more detail, each longitudinal beam 11.1 and 11.2 is provided with several, in this case at least two, pairs of different mounting pins 300, 40. At least two (upper) mounting pin units 3.1, 3.2 or 3.3, 3.4 are provided at an upper edge of each longitudinal beam 11.1 and 11.2. Each of these mounting pin units 3.1 to 3.4 engages an upper edge of the respective longitudinal beam 11.1 or 11.2 with a bearing block 31. A pivot bearing element 30 is pivotably mounted on this bearing block 31. The mounting pin 300 is formed on the pivot bearing element 30, which thus moves between a non-use position corresponding to the Figures 6B and 7B and a usage position according to the Figures 5A , 6A and 7AThe pivot bearing part 30 is pivotable on the longitudinal beam 11.1 or 11.2. In a working position, the pivot bearing part 30 with the mounting pin 300 projects into the pocket 10, allowing a container to be secured to it. In the non-working position, the mounting pin 300 is pivoted outwards from the pocket 10. In the non-working position, a container can thus be arranged on the double pocket trolley 1 without being secured to the mounting pin units 3.1 to 3.4 (see, e.g., [reference]). Figures 8A to 9B ) and, if necessary, also past the attachment pin units 3.1 to 3.4 into the interior of pocket 10 (see e.g. Figures 11A to 11B ).

[0040] The mounting pin units 3.1 to 3.4 can, in principle, be fixedly positioned on the longitudinal beams 11.1 and 11.2. In the illustrated embodiment, the mounting pin units 3.1 to 3.4 can be freely positioned along a longitudinal beam 11.1, 11.2 in the area of ​​pocket 2, in particular, they can be moved. In this way, differently distributed attachment points for various types of ISO containers and swap bodies can be provided via the mounting pin units 3.1 to 3.4 on the longitudinal beams 11.1, 11.2. The (upper) mounting pin units 3.1 to 3.4 can also be detachably fixed to the longitudinal beams 11.1 and 11.2, so that a mounting pin unit 3.1 to 3.4 can be completely removed from a longitudinal beam 11.1 or 11.2 if necessary.

[0041] Furthermore, additional (lower) mounting pin units are provided on the inner sides of the longitudinal beams 11.1 and 11.2. Two mounting pin units are provided on each longitudinal beam 11.1, 11.2, of which only mounting pin units 4.1, 4.2, and 4.4 are shown in the accompanying figures. Each mounting pin unit 4.1, 4.2, or 4.4 has a bearing block 41, by which the respective mounting pin unit 4.1, 4.2, or 4.4 is held on the inner side of a longitudinal beam 11.1 or 11.2. A mounting pin 40 is formed on each bearing block 41, which can be used for fixing an ISO container. The individual mounting pin units 4.1, 4.2 and 4.4 can, in principle, be mounted longitudinally displaceable on a longitudinal beam 11.1 or 11.2 in order to achieve additional flexibility for different container sizes and to be able to position the mounting pin units in different positions on a longitudinal beam 11.1 or 11.2.

[0042] In principle, the position and number of the mounting pin units 3.1 to 3.4 and 4.1, 4.2, 4.4 are not limited. For example, they can also be arranged as shown in the diagram. Figure 3 An additional mounting pin unit 3.5 is provided on a longitudinal beam 11.2. In principle, the mounting pin units 3.1 to 3.5 as well as 4.1, 4.2 and 4.4 can be designed to be mobile in order to accommodate ISO containers and swap bodies of different sizes both above and within a pocket 10 on the double pocket trolley 1.

[0043] As particularly evident from the Figures 8A to 11B As illustrated in different views, the configuration of the double pocket wagon 1 shown allows in particular flexible loading of the double pocket wagon 1 with containers C45, C40 and C20 of different sizes.

[0044] For example, according to the representations of the Figures 8A to 8DA 45-foot container C45 can be loaded onto each pocket trolley 1A or 1B. Such a 45-foot container C45 is placed on the loading platforms 120 and 130 of the end piece 12 and the end piece 13. The pivotally mounted mounting pins 300 of the mounting pin units 3.1 to 3.4 are pivoted into a non-use position. The respective 45-foot container C45 is neither on a tray 2 nor within a pocket 10 of the pocket trolley 1A or 1B. Rather, the double pocket trolley 1 is structured such that, when loaded as intended, the 45-foot container C45 extends over the pocket 10 and the tray loading platform 20 of the suspended tray 2. Even when loaded with a 45-foot container C45, the tub 2 can be easily attached to the longitudinal beams 11.1 and 11.2 and transported along with it.

[0045] Accordingly, the following also illustrate Figures 8A to 8Dthe double pocket wagon 1 loaded with two 45-foot C45 containers without tubs 2, while the Figures 9A and 9B The same loading situation is illustrated using two 45-foot C45 containers with suspended tubs 2.

[0046] Transport of 40-foot C40 containers according to the Figures 10A and 10B This is possible independently of the tub 2. A 40-foot container C40 is given a transport position via the mounting pins 300 of the upper mounting pin units 3.1 to 3.4, which are pivoted into their operating position, in which these 40-foot containers C40 also extend over a pocket 10 and thus over a tub 2 suspended therein.

[0047] The same applies to a transport position specified with the lower mounting pin units 4.1, 4.2 and 4.4 for 20-foot C20 containers according to the Figures 11A and 11BThe 20-foot C20 containers rest partially within pocket 10, supported by the mounting pin units 4.1, 4.2, and 4.4 located on the inner sides of the longitudinal beams 11.1 and 11.2 (and thus within pocket 10), when loaded as intended onto the double pocket wagon 1. However, the arrangement of the mounting pin units 4.1, 4.2, and 4.4 in relation to the suspension pins 110a and 110b for the suspended tub 2 ensures that the 20-foot C20 container is in its designated transport position above the tub loading area 20 of the suspended tub 2. Consequently, it neither rests on the tub loading area 20 nor is the transportability of the tub 2 affected by the loading of a 20-foot C20 container.

[0048] Furthermore, in order to efficiently transport different types of cargo that cannot be easily lifted by crane using tub 2, tub 2 has a feature integrated into the Figures 12A to 16BRamp assembly 200 shown in different configurations and ramp positions.

[0049] This ramp assembly 200 comprises several (in this case four) ramps 201, 202, 203 and 204 as well as two ramp extensions 205 and 206. The ramps 201 to 204 and ramp extensions 205, 206 of the ramp assembly 200 are provided with 20 different ramp positions on the tub loading area, which simplify efficient loading of the tub 2 with different cargo.

[0050] In a first, in the Figures 12A and 12B In the ramp positions illustrated in different views, the four ramps 201 to 204 are arranged in pairs, each with ramp extensions 205, 206 positioned between two ramps 201 / 204 or 202 / 203. Each ramp 201 to 204 has a pivot bearing part 201a, 202b, 203c or 204d, by means of which the respective ramp 201, 202, 203 or 204 is fixed to the tub loading surface 20.

[0051] Each articulated bearing section 201a to 204d is connected to a ramp unit 200a, 200b, 200c or 200d of a ramp 201, 202, 203 or 204. The respective ramp unit 200a, 200b, 200c or 200d of a ramp 201, 202, 203 or 204 is located in the Figures 12A to 12B The illustrated (first) ramp position does not extend beyond the longitudinally extended loading surface 20 of the tub, or at most only slightly, and is positioned essentially centrally on the loading surface 20 of the tub. In this first ramp position, the two ramp extensions 205 and 206 are furthermore detachably fixed to the pivot bearing parts 201a to 204a via fixing pins 200.1 and 200.2, and are thus also held in its defined position on the ramp surface 20 of the tub 2.

[0052] The in the Figures 12A and 12B The first ramp position of ramp assembly 200 shown is for loading tub 2 with a semi-trailer T1 or T2 according to the Figures 17A and 18Bset up and provided for. With the tub 2 removed and placed on the ground, the semi-trailer T1 can, for example, be driven into the tub 2 by means of a tractor unit L and fixed to the tub loading platform 2 (see Figures 18A and 18B The individual components of the ramp assembly 200 are located centrally between the wheels R of the semi-trailer T1. The semi-trailer T1, which has been driven into and secured against the trough 2, can then be loaded into the pocket 10 of a pocket trolley 1A or 1B of the double pocket trolley 1 using the trough 2, as shown in the Figures 17A and 17B The diagram shows the two semi-trailers T1 and T2. A kingpin of the respective semi-trailer T1 or T2 is then received and secured on the pin receptacle 121 of the respective headpiece 12.

[0053] As shown by the Figures 13A-13B and 15A-15BAs illustrated, a ramp assembly 200 can also be arranged in a predefined second ramp position on the tub 2. In the second ramp position, the ramps 201 to 204 are offset transversely and parallel to one direction of extension compared to the first ramp position. Thus, in the illustrated second ramp position, the ramps 201 to 204, which are offset parallel to the first ramp position, project further beyond an end edge of the tub 2 than in the first ramp position, thereby providing a transport area for a semi-trailer truck L1 to L4 that extends beyond the edge of the tub 2 (see, e.g., [reference]). Figure 19The individual ramps 201 to 204 are arranged in pairs at the two longitudinal ends of the loading platform 20 such that each ramp 201 to 204, with its ramp unit 200a to 200d, projects beyond one end of the loading platform 200. Ramp extensions 205 and 206 can then be arranged on two ramps 201 and 204 assigned to one longitudinal side, so that driveable ramps of different lengths project from the two end faces of the loading platform 20. The ramps 201 to 204 of the two pairs of ramps 201 / 204 and 202 / 203 are arranged transversely to each other essentially according to the track width of a semi-trailer truck L1 to L4, so that a semi-trailer truck L1, L2, L3 or L4 driven into the platform 2 can be positioned according to the Figures 19 , 20 and 21A to 21B with their wheels on ramps 201 to 204 and ramp extensions 205 and 206.

[0054] The pivoting bearing on the articulated bearing components 201a to 204d allows the two tractor units L1 / L2 or L3 / L4 positioned on the tub 2 to be tilted towards each other in the pocket 10 into which the tub 2 is inserted, thus enabling a more space-saving arrangement. The ramps 201 to 204, which extend beyond the end faces of the tub loading platform 20 and on which the tractor units L1 to L4 rest, consequently protrude beyond a pocket 10 of the double-pocket trailer 1 (significantly more than in a first ramp position). In this configuration, the ramps 201 to 204 cannot be accommodated within the tub 2 and, during the loading process, rest against the head piece 12 and the end piece 13.This means that as the tub 2 is lowered further into pocket 10, the protruding ramp units 200a to 200d will pivot at the articulated bearing parts 201a to 204d. The second ramp position of the ramp assembly 200 is thus predetermined such that tractor units L1, L2 or L3, L4 positioned on the tub 2 will tilt towards each other – when the tub 2 is inserted into pocket 1 and otherwise without any further intervention.

[0055] Based on the Figures 14A-14B and 16A-16BIt is further illustrated that, for positioning tractor units L1 to L4 at the hopper 2, the ramp extensions 205 and 206 do not necessarily have to be arranged at ramps 201 to 204. The ramp extensions 205 and 206 can also remain fixed centrally between two ramps 201, 204 or 202, 203 on the hopper loading platform 20. In this way, the ramp extensions 205 and 206 can easily be carried along even if no tractor units L1 to L4 are positioned on them, for example, because only two-axle tractor units L2, L3 are to be transported on the double pocket wagon 1.

[0056] As shown in the sectional view of the Figure 22As illustrated, the proposed design of the double pocket wagon 1 with the tub 2 suspended in pocket 10 also readily allows the transport of a single tractor unit L2. The tractor unit 2 is then positioned completely on the tub loading platform 20 and transported by means of the tub 2 in pocket 10 of a pocket wagon 1A or 1B double pocket wagon 1.

[0057] Based on the Figures 23A-23B , 24 , 25 , 26A-26B and 27It is further illustrated that the double pocket wagon 1 can also be used for loading cargo using the roll-on / roll-off method. In this case, a functional position on the pocket 10 is defined by the pivoting mounting pins 300 of the upper mounting pin units 3.1 to 3.4 of each tub 2 of a pocket wagon 1A, 1B, in which the tub loading surface 20 of the respective tub 2 is positioned at the level of the loading surfaces 120 and 130 of the head piece 12 and the end piece 13. A loading surface 120 on the head piece side, the tub loading surface 20 of the tub 2, and a loading surface 130 on the end piece side thus provide a continuous wagon loading surface similar to a flat wagon, onto which cargo can be driven.

[0058] For the specification of the in the Figures 23A to 27In the functional position of a tub 2 shown, the attachment units 3.1 to 3.4 can also be positioned differently, in particular differently compared to a position on the longitudinal beams 11.1 and 11.2, which the attachment pin unit 3.1 to 3.4 occupy for loading the double pocket wagon 1 with one or more 40-foot containers.

[0059] The tub 2 has connecting openings on its underside to allow it to be placed onto the mounting pins 300 of the mounting pin units 3.1 to 3.4 and secured thereto. No additional fastening or fixing elements are required. The double pocket trolley 1 can be configured for transporting almost any type of cargo using the tub 2 and the mounting pin units 3.1 to 3.4 and 4.1, 4.2, 4.4, which are provided on the opposing longitudinal beams 11.1, 11.2.

[0060] When a continuous loading platform is provided by the trough 2 held in a functional position on the mounting pins 300, the ramp assembly 200 of the trough 2 can also be in the second ramp position, so that tractor units L5 to L8 can drive onto the ramps 201 to 204 and, if necessary, the ramp extensions 205 and 206. To enable the tractor units L5 to L8 to drive onto the continuous loading platform at one end of the double pocket wagon 1, standard loading ramps 207 and 208 are, for example, fixed to an end piece 12.
