DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD OF THE INVENTION
This invention relates to a railway waggon comprising on one hand a load carrier composed of at least two separate carrying beams and a platform part extending therebetween, and on the other hand front and rear bogies having wheels for railway rails or railway tracks, the platform part being located on level with or below the carrying beams, which at their opposed ends change into jibs located on a higher level than the beams per se, in order to be applied on top of the bogies, without markedly distancing the platform part vertically from the wheel base of the bogies, the load carrier being detachably connected with each one of the bogies in order to, in an inactive state in connection with loading and unloading, be displaceable with each end laterally relative to an imaginary geometrical longitudinal axis between the bogies, so that in this way a removal of the load carrier is made possible to a position distanced from the bogie or bogies, in which position a vehicle may be driven on and off the platform part in the area between the carrying beams of the load carrier.
BACKGROUND OF THE INVENTION AND PRIOR ART
Modern logistics rely to an increasing extent upon combined railway and road transports. Thus, a common way of distributing goods is to transport the goods a shorter distance in a near region on a lorry set to an existent railway, where the lorry set in its entirety is loaded upon a railway waggon comprised in a train unit, which in turn is driven a longer distance to the proximity of the place of destination, whereafter the lorry set is unloaded and driven a shorter distance on the road to the receiver. Combined railway and road transports of this type necessitate specially built railway waggons to fulfil the railway norms for train units. More specifically, the railway waggons must be constructed in such a way that the whole carriage with the on-loaded lorry manages the so called standard profile cross-section which is used to determine whether a train unit is able to pass, e.g., tunnels, subway crossings, short radius curves, etc.
The proposals for railway waggons for the above mentioned purposes are many and abundantly described in the patent literature. Hitherto disclosed constructions may be divided into two main categories, namely a first category that is based on the principle of driving the load vehicles one after the other onto a train unit, starting at one end of the train unit, the first road vehicle being driven along the train unit from one end to the other, and a second category that makes use of some sort of platform built upon the chassis of the railway waggon, said platform being turnable or pivotable relative to the chassis. Examples of railway waggons belonging to the first category are described in DE 41 12 995 and EP 293 359. Examples of waggons belonging to the second category are described in GB 2 198 405, EP 207 491 and SE 8206181-3.
In practice, a disturbing drawback of the railway waggons of the first category is that an arbitrary road vehicle cannot separately be driven off the train unit, i.e., a given road vehicle cannot be removed from the train unit without that either the vehicle in front of or at the back of the same has first been driven off the train unit. This drawback is not inherent in the railway waggons of the second category, in that individual platforms may be pivoted or turned relative to the appurtenant waggon without any connection with other waggons in the train unit, but in return of this such railway waggons have other serious disadvantages. Thus, long road vehicles may not be driven on and off the railway waggon without the platform protruding a considerable distance from the side or sides of the waggon. Moreover, the platform per se adds to the height; a fact that either involves that the waggon has to be equipped with costly arrangements for raising and lowering the platform relative to the waggon chassis, or that the railway waggon has to be made with extremely small wheels in order to manage the previously ment
