Description

The invention relates to a transport platform for loading, transporting and storing goods according to the preamble of claim 1.

Commonly known is the use of standardized ISO containers made of a steel construction, with the help of which a simple and fast loading, transporting, storing and unloading different goods is possible. The ISO containers may be provided by way of example as a 20-foot container or a 40-foot container. Such an ISO container may be completely or partially closed on its longitudinal sides and / or its roof side, with corresponding end, bottom, top and / or side walls. The ISO container also has standardized ISO corner fittings (so-called container corners) at least on its eight outer corners, with the aid of which the ISO container can be locked in a simple and fast manner with, for example, a trailer contour of a truck semitrailer or other modes of transport as well as the ISO Container can be stacked in several container layers.

From the DE 195 03 557 A1 is a generic transport platform known. The transport platform is designed as an externally closed cube-shaped container with sheet metal planking. From the AT 007 105 U1 is a method for unloading a transport vehicle of containers or for loading the same known. From the DE 198 33 872 A1 is a chassis for stacking / changing and tilting container for placing on Trucks known with loading crane. From the DE 42 14 352 A1 a device is known for securing containers immediately stowed on foundations in the loading area of vehicles.

The object of the invention is to provide a transport platform whose field of application is functionally extended to the extent that it allows for different load simple loading or unloading.

The object is solved by the features of claim 1. Preferred embodiments of the invention are disclosed in the subclaims.

In order to increase the loading volume available from the transport platform, according to the characterizing part of claim 1, the transport platform is extended in a platform longitudinal direction with a front projection and a rear projection on the front / rear corner fittings out. The respective front / rear supernatant terminates at a front / rear vertical frame. This is each constructed of vertical struts and an upper roof cross member, which converge on a roof frame corner. The roof frame corner is connected in the platform longitudinal direction via a longitudinal support strut on the roof corner fitting. To increase the stability of the platform during loading of the transport platform, a longitudinal support strut is supported in each case between the roof corner fittings arranged in longitudinal alignment with each other.

In a technical implementation, the bottom group of the transport platform may have two mutually parallel lateral side members. These are connected together to form a closed horizontal support frame at least on end-side cross member. The soil group thus formed is designed as a steel beam construction on which preferably a closed bottom wall is formed.

By means of the bottom corner fittings, the transport platform on a semi-trailer contour, such as a truck semi-trailer or other mode of transport, lockable. The roof corner fittings ensure that the transport platform can be stacked in several layers. In addition, a further transport platform stacked on the transport platform can be locked via the roof corner fittings. Alternatively, during a loading operation, a container handler may engage the roof corner fittings to load the transport platform. Such container stackers are used in common practice when loading ISO containers and are, for example, in loading yards in use.

In this way, the transport platform in the manner of a conventional ISO container in a simple manner between different modes, for example between the train and a truck semi-trailer, reloaded, by means of an above-mentioned container stacker for reloading such ISO containers. It is preferred in this case if the floor and roof corner fittings are designed as ISO container corner fittings, as they are installed in a conventional ISO container. In addition, the distances between the upper and lower corner fittings may be substantially identical to the distances between the ISO container fittings installed in the ISO container.

The rear projection is positioned at the semi-trailer rear side in the case of a transport platform loaded on a truck semitrailer. To realize the rear projection, the two platform side members can be extended beyond the rear floor corner fittings out and attached directly to the rear vertical frame (that is, welded). The rear vertical frame is from the above Vertical struts, the roof cross member and a floor cross member constructed which connect the two platform side members at the rear.

The front projection is facing a loaded on a truck semi-trailer transport platform in the direction of a truck cab. To realize the front projection, the two platform side rails can be approximately complete on the front floor corner fittings and (with respect to the platform side members) cross-section reduced floor longitudinal struts extended forward. The floor struts and vertical struts of the front vertical frame converge on a floor frame corner with a floor cross strut. The floor cross strut connects the two floor longitudinal struts front to each other.

The front (or cab-side) supernatant may be offset from the platform underside to form a bottom clearance with a height offset. In addition, the front projection is dimensioned such that adjoining components of the truck cab or the truck semi-trailer, for example, hydraulic lines or the like, are spaced over a sufficiently large clearance of the transport platform. In a constructive embodiment can be spanned between the bottom longitudinal strut and an end face of the platform side member a step-like Inneneckbereich which forms the above-mentioned bottom-side space.

When loading cargo sideways onto the transport platform, it is important that the transport platform provides as free side cargo access as possible. Therefore, a significant advantage of the invention is that the positioned in each platform corner area floor and roof corner fittings are spaced from each other over a clear height. That is, the floor and roof corner fittings are not directly connected in the vertical direction by means of a vertical support, which at a lateral loading of cargo using a forklift would form a disturbing contour that affects the charging process.

Seen in the side view, therefore, form the built-in front projection supernatant, the front vertical strut and the bottom longitudinal strut a C-shaped support structure, which connects to the front floor and roof corner fittings. In the same way, built in the rear projection supernatant, the rear-side vertical strut and the platform side member form a C-shaped support structure, which connects to the rear-side floor and roof corner fittings.

Preferably, the side-by-side arranged in cross-flight roof corner fittings over a clear width, ie, without intermediate cross strut, spaced from each other, which also a simpler loading or unloading is possible, which is not affected by interference contours (that is, by a cross member).

The front (leader-side) supernatant may be at least partially provided with a sheet metal planking. Preferably, the sheet metal paneling may have a closed vertical end wall facing the truck cab, which closes the front vertical frame.

Between the front floor cross strut, the front platform cross member and the longitudinal floor longitudinal struts a lying in a horizontal plane bottom frame is formed. This can also be closed by means of a horizontal bottom wall. In addition, the platform floor assembly may be closed with a bottom wall that may be constructed from a plurality of wood panels.

In a stable construction implementation of the transport platform, the support strut and the support strut material uniform and / or one-piece Be part of a common roof longitudinal strut. The roof longitudinal strut carries the roof corner fittings, each spaced by a longitudinal offset from the outer roof frame corners.

Preferably, the roof-side support struts, the roof-side support strut, the vertical struts and the platform side member can limit at least one open transport platform longitudinal side, which is not covered by a sheet metal paneling. Alternatively or additionally, the roof transverse struts and the roof-side support struts and struts limit an open transport platform roof side, which is not covered by a sheet metal planking.

In a preferred embodiment of the transport platform whose longitudinal sides can be closed by means of a side tarpaulin. The side tarpaulin is preferably guided displaceably on the roof longitudinal strut. When loading with a forklift truck, the side curtain can be moved to expose side loading / unloading access. Alternatively and / or additionally, the transport platform roof can be covered with a roof tarp, which can also be displaceable in the longitudinal direction. Alternatively and / or additionally, at least one portal door can be installed in the rear-side vertical frame, by means of which the transport platform can be closed on the rear side.

Depending on the load, a lateral transport lock on the transport platform may be required. For this purpose, the platform floor group stanchions can be releasably attached on both sides. The stakes are respectively connected to attachment points of the bottom group, that is fixed or detachable on the two side rails. Preference is given to a detachable plug-in system in which the respective stanchion can be detachably inserted into a stanchion pocket positioned on the platform side member. In this way, the stanchion can be easily replaced for repair purposes. The stanchions can each be positioned in a platform vertical direction approximately in alignment below the longitudinal roof-side support strut. With regard to a simple assembly / disassembly of the stanchions, it is preferred if it is arranged with its upper sides by a free distance below the respective support strut. In this case, the stanchions are positioned without connection with respect to the roof-side support strut.

The platform stability can be further enhanced if the stanchions are cross-aligned in the cross-platform direction. In addition, the two platform side members may be connected to each other at the stake attachment points via floor cross struts. The floor cross braces and the stanchions thus converge at the stanchion connection points of the platform longitudinal members to form a junction through which forces can be introduced into the support structure.

In a further development, the platform floor assembly may have a centering profile on the underside, which can be brought into contact with a corresponding semitrailer counter profile when loading the transport platform on a truck semitrailer in order to ensure correct positioning of the transport platform on the semi-trailer.

The centering profile can be realized as a Zentrierblechteil, which has an upwardly open center tunnel in the platform vertical direction upwardly recessed, horizontal centering surface, which merges in the platform transverse direction outwardly into obliquely downward run-up slopes. The corresponding counter contour of the truck semitrailer can be realized by means of upwardly cranked guide rails of a so-called Gouseneck chassis of the semitrailer, via which the platform-side centering plate is placed positively in the correct position lowering the transport platform.

The Zentrierblechteil may preferably be connected in the platform longitudinal direction front of the front (driver's cab side) platform cross member.

For locking transport platforms with one another and / or with a carrier vehicle, closure elements (for example twistlocks) are known with the aid of which the corner fittings can be brought into positive connection with the carrier vehicle or with a further transport platform.

Hereinafter, an embodiment of the invention with reference to the accompanying figures will be described.

FIGS. 4 to 7

in each case enlarged detail views of the transport platform.

Based on FIGS. 1 to 3 the structure of a transport platform is described below, which is designed for loading different goods. The transport platform is realized as a steel girder construction which has a floor assembly as well as later-described overhangs 21, 23 described later. The floor group is in the FIG. 1 is constructed from two mutually parallel lateral platform side members 9, the forklift pockets 66 (FIG. FIGS. 1 and 2 ) exhibit. The platform side members 9 extend in a platform longitudinal direction x and form together with end-side platform cross members 11 form a closed horizontal support frame.

The platform side members 9 and the platform cross member 11 are exemplified in the figures as I-beam profile parts, but not limited to such an I-profile. At each of the four platform corner areas are in each case a bottom corner fitting 13 and a roof Eckbeschläg 15 welded. The floor and roof corner fittings 13, 15 are designed as standardized ISO container corner fittings, with fastening eyes 16 (FIG. FIGS. 6 or 7 ), in which closure elements, not shown, can engage. Similarly, the distances of the bottom and roof corner fittings 13, 15 are substantially identical to the standard distances of ISO container corner fittings in a conventional ISO container. By way of example, the spacings of the floor and roof corner fittings 13, 15 in the platform spatial directions x, y, z can respectively correspond to the corresponding distances of container corner fittings in a 40-foot ISO container.

In order to ensure a lateral transport safety of cargo, 9 stanchions 17 are attached to the two lateral platform side rails, their connection to the platform side members later based on the FIG. 4 is explained.

The transport platform is specially designed for loading onto a truck semitrailer. In the loaded state is in the Figure 1 to 3 The left side of the transport platform facing the truck cab and positioned the right side of the transport platform on the semi-trailer rear side. Like from the FIGS. 1 to 3 further shows, the transport platform in the platform longitudinal direction x is frontally extended beyond the corner fittings 13, 15 with a rear projection 21 and a leader-side (front) projection 23.

To realize the rear projection 21, the two lateral platform longitudinal members 9 extend continuously over the floor corner fittings 13 and close them off on a closed rear-side vertical frame 25. In the FIGS. 1 to 3 is the circumferentially closed vertical frame 25 constructed of a bottom cross member 27 which extends between the two platform side rails 9, and out Vertical struts 29 constructed, which converge at the upper frame corners I with a roof cross member 31. The two upper frame corners I of the rear-side vertical frame 25 are connected by longitudinal support struts 33 with the upper roof corner fittings 15.

In approximately the same way, the front-side, protruding forward cab-side projection 23 is realized: According to the FIGS. 1 to 3 close the two platform side members 9 approximately at the front floor corner fittings 13 and these are extended with reduced cross-section floor longitudinal struts 22 which are connected to a front-side vertical frame 24. The front vertical frame 24 has a bottom cross member 27 which connects the two bottom longitudinal struts 22 frontally, namely to form a bottom frame corner II, at the bottom cross member 27, the respective bottom longitudinal strut 22 and front vertical struts 29 of front vertical frame 24 converge.

As a result of the above-described frame construction of the front and rear projections 21, 23, the bottom corner fittings 13 and the roof corner fittings 15 are above a clear height h (FIG. FIG. 3 ) spaced apart to allow for a forklift a simple side loading without interference contours.

In the side view ( FIG. 3a ) considered thus formed in the front projection 23 support strut 33, the front vertical strut 29 and the bottom longitudinal strut 22 form a front C-shaped support structure. The front C-shaped support structure extends the transport platform forward and adjoins the front floor and roof corner fittings 13, 15. As a result, an additional, easily accessible loading space for load 1 is provided. In the same way, according to the FIG. 3b the built-in rear projection 21 support strut 33, the rear vertical strut 29 and the platform side member 9 a rear C-shaped support structure, which connects to the rear-side floor and roof corner fittings 13, 15.

Likewise, the roof corner fittings 15 arranged side by side in a transverse alignment are over a clear width b (FIG. FIG. 1 ) spaced apart. The front vertical frame 24 is closed by means of a vertical front sheet metal wall 34. In addition, the front floor cross brace 27, the front platform cross member 11 and the floor longitudinal struts 22 together form a horizontal floor frame, which is closed by means of a horizontal bottom sheet metal wall 36.

The front projection 23 is in the FIGS. 1 to 3 forming a bottom free space 41 by a height offset Δz ( FIG. 2 ) stepped from the platform bottom stepped upwards. Between the bottom longitudinal strut 22 and an end face of the platform side member 9, an inside corner area is thus spanned (viewed in the side view), which forms the bottom-side free space 41.

Like from the FIGS. 1 to 3 further shows, between the roof corner fittings 15 each a longitudinal support strut 37 is supported, in which in a later described loading operation ( FIG. 3 ) acts as a compression strut which increases the transport platform stability. The support strut 37 and the two front and rear support struts 33 are in the FIGS. 1 to 3 uniform material and one-piece components of a roof longitudinal strut 39, which extends completely continuously between the upper roof frame corners I. The roof corner fittings 15 each by a longitudinal offset Δx ( FIG. 2 ) are spaced inwardly from the outer roof frame corners I.

When fully assembled transport platform, the transport platform longitudinal sides by means of a side curtain 52 (in FIG. 1 indicated) closable, which is guided displaceably on the roof longitudinal strut 39. Likewise spanned (in the FIG. 1 partially indicated) a roof tarpaulin 54 a transport platform roof. In the rear-side vertical frame 25 is an in the FIG. 1 dashed line portal door 56 installed. On the floor assembly is a closed bottom wall 58 ( FIG. 1 ), which is composed of a plurality of wood panels.

Based on FIG. 3 illustrates a load case that results in a loading process of the transport platform. Consequently, the transport platform is lifted by means of a gripper 65 of a container stack indicated only by dashed lines. The gripper 65 is engaged with the four upper roof corner fittings 15 of the transport platform and locked thereto by actuation of closure elements (for example twistlocks). In this case, due to the platform weight, a load path L ( FIG. 3 ) via the upper roof corner fittings 15, which fork in the platform longitudinal direction x in the upper support strut 33 and in the support strut 37, which acts as a compression strut in this load case. In the further course of the load path on the front / rear vertical frame 24, 25 in the bottom group 5 of the transport platform, namely while bridging the clear height h between the roof and floor corner fittings 13, 15th

Like from the FIG. 3 further shows, the transport platform on its front underside a centering profile 43 which is welded in the platform longitudinal direction x front on the front cross member 11. The centering profile 43 cooperates with a corresponding counter-profile on the truck semi-trailer to ensure a correct position positioning of the transport platform on the truck semi-trailer.

In the FIG. 4 is shown in a detailed view in each case the plug-in system, with which the stanchions 17 are detachably mounted on the longitudinal members 9. The plug-in system has a Rungentasche 53, which in a material recess 51 of the longitudinal member used and welded to it. The stanchion 17 can be inserted with its lower wedge-shaped end in a form-fitting manner in the likewise wedge-shaped stanchion pocket 53. Optionally, the stanchion 17 may be secured in the stanchion pocket 53 via securing means (not shown).

In order to increase the stability of the platform, two laterally opposite stanchions 17 are each aligned in a transverse plane y in a transverse plane y. In addition, in each transverse plane yz runs a transverse strut 27, which is connected in each case to the stake attachment points of the lateral side members 9. The stanchions 17 are with their tops to a free distance a ( FIG. 1 ) are arranged below the longitudinal support struts 37.

In the FIG. 5 is shown in a further detail view of the rear projection 21 partially. Consequently, the longitudinal member 9 extends continuously over the bottom corner fitting 13 also to the rear vertical frame 25. At its lower frame corner run the bottom-side cross member 27 and the vertical strut 29 on the longitudinal member 9 together.

Like from the FIG. 5 shows, the cuboid bottom corner fitting 13 is welded into a material cutout 55 of the longitudinal member 9 and the cross member 11. For corner stiffening is in the FIG. 5 between the bottom corner fitting 13 and the upper T-flange of the longitudinal member 9 a reinforcing sheet metal part 57 is supported. Corresponding reinforcement sheet metal parts 57 are also installed on the further floor corner fittings 13.
