The invention concerns a transport wagon for cargo according to the preamble of claim 1 wherein such transport wagons, aside from cargo of agricultural harvested goods, in particular in the form of compressed round bales, can also be used for compressed paper waste, plastic bales, or like materials.
According to DE 33 12 585 A1 a transport system is provided for compressed bales that are present in round or parallelepipedal shape and comprised of compressed raw feed or the like harvested goods. On a transport wagon several bale receiving boxes are provided that receive the round bales in an ordered structure. In these boxes the round bales, on the one hand, can be transported and, on the other hand, the system is designed such that the boxes combined to a container also can be used for storing the round bales until they are being used in accordance with their purpose.
DE 200 22 895 discloses a transport wagon that is configured as a collecting vehicle that has at its rear a receiving device for the cargo from where the pieces that are particularly embodied as silage bales can be transported onto a load platform delimited by stationary sidewalls wherein for this transport a special roller table is provided in the area of the load platform. As a result of these additional components the utilizable transport space is disadvantageously limited.
The invention concerns the problem of providing a transport wagon for agricultural cargo with which, in adaptation to traffic regulations, a maximized cargo volume can be received so that high transport quotas are possible and, in the area of the load platform, cargo securing adaptable to different loading states can be achieved with minimal expenditure.
The invention solves this problem by a transport wagon with the features of claim 1. Further advantageous embodiments result from claims 2 to 17.
In accordance with the present invention, the transport wagon provided with sidewalls that can be moved into open position has in the area of at least one of the longitudinal sidewalls an improved support device with whose lifting linkage provided with a drive the cargo that forms a multi-layered stack can be engaged by the longitudinal sidewall in such a way that an additional lateral clamping fixation is achieved. By means of a variable controllable pivoting and lifting movement in particular the upper layer of the stack can be positionally precisely engaged and laterally pressed so that in this way for a maximum load height on the platform permitted for traffic a greater stability of the stack is achieved and risks as well as loss of cargo are avoidable.
In particular, both longitudinal sidewalls connected to the at least one support device can be placed against the cargo pieces like a clamping gate by synchronous movement. In this pressing or clamping position only a partial area of the lateral surfaces of the multi-layer stacked cargo is engaged on the transport wagon. In an upper contact position, a free space is generated laterally in the lower area between the clamping gate and the platform where pieces of the cargo stack are openly and laterally accessible. In an inventive further embodiment of the clam ping construction with the clamping gate additional securing elements are provided in the area of the free space. In an expedient embodiment they can interact with the longitudinal sidewalls or the support device/devices.
As securing elements, in particular flexible clamping parts are provided in this connection that upon movement of the clamping gate into the upper closed position are entrained and in this way substantially completely placeable laterally against the stacked cargo. In this way, for the lower layers of cargo an additional securing action is provided. With this embodiment of the securing elements it is possible to also load the transport wagon in such a way that the load projects past the constructively predetermined width of the load platform so that, for example, two stacks of round bales or similar cargo pieces positioned parallel to the longitudinal center plane of the transport wagon are transportable and the lateral securing elements prevent reliably a displacement of cargo out of a stack transversely to the traveling direction even when maneuvering a curve.
Further details and advantageous embodiments of the invention result from the drawing in which two embodiments of the transport wagon according to the invention are illustrated. The drawings show in:
In
According to the invention the transport wagon 1 in the area of at least one of the sidewalls 3, 3′ (in the illustrated embodiment both walls 3, 3′) is provided with a support device S by means of which the longitudinal sidewalls 3, 3′, starting from an open position A (for loading), are movable (on a movement path in accordance with dash-dotted line R;
A weight-optimized narrow embodiment (width T,
These longitudinal sidewalls 3, 3′ however create a zone Z below the longitudinal sidewalls 3, 3′ in the closed position that remains “free” so that in this area there is the risk that the cargo that is located in a lower or middle layer L′ (
The side views according to
With this functional assembly connection S, S′ and 7, 7′ in the area of the longitudinal sidewalls 3, 3′ a pivoting and clamping system is formed in which the walls 3, 3′ provided with bucking-resistant rod elements 8, 8′ and 9 are each acting like a clamping gate K, K′, respectively (arrow F,
It is understood in this connection that these longitudinal sidewalls 3, 3′ each are provided, preferably at the lower edge of the clamping gate K, K′ in the area of their horizontal rod 8′, with the securing elements 6 extending toward the edge area of the load platform 5 (
In this connection, the clamping gates K, K′ are pivotable upwardly from a ground-near loading position (lower position A,
The securing elements 6 are in particular in the form of flexible tensioning parts. In an exemplary fashion, tarpaulins, ropes 21 (
The end view according to
The movement path R that is followed by the two clamping gates K, K′ by means of the support devices S, S′ is illustrated by an arc. By means of arrow H a measure for a conceivable maximum loading height (for example, 4 m) of the load wagon 1 is illustrated. When the load wagon 1 travels empty, it has a width that matches the width P in accordance with traffic regulations (for example, 2.55 m) and in the loaded state the system may have a loading width P′ (for example, 3 m) so that in the traveling direction stacking of correspondingly long cargo pieces 2, 2′ and 2″ is possible (
