  • the same adjustment system (5) can for example comprise a first height positioning device (50) comprising a step wedge (51) (see figures 35 to 36 ) or a rotary cam (53) (see figures 37 to 38 ), and a second height positioning device (50) comprising an articulation (55) by which the rigid receptacle (47) is pivotally mounted on the loading platform (2).
  • a first height positioning device (50) comprising a step wedge (51) (see figures 35 to 36 ) or a rotary cam (53) (see figures 37 to 38 )
  • a second height positioning device (50) comprising an articulation (55) by which the rigid receptacle (47) is pivotally mounted on the loading platform (2).
  • the articulation (55) can be fixed or removably mounted on the loading platform (2). This assembly can be indexed in position.
  • the adjustment system (5) can also comprise suspension devices (52), for example in the form of springs, which are provided between the loading platform (2) and the peripheral edges (49) of the rigid receptacle (47).
  • suspension devices (52) By relieving the weight of the rigid receptacle (47), these suspension devices (52) make it possible to facilitate the handling of the support device (9) during height adjustment operations of the wheel (4) of the road vehicle (3 ).
  • the support device (9) is mounted directly on the loading platform (2).
  • the support device (9) can be mounted either on the loading platform (2) via a movable plate (56).
  • the support parts (10) for the wheels (4) are represented schematically by parallelepipeds, because this variant of the invention can be adapted to all types of support part (10) previously described or possible.
  • the movable plate (56) replaces the surface of the loading platform (2) on which the support device (9) of the invention is mounted.
  • the additional immobilization devices and the longitudinal rails which, according to the other variants, are provided on the loading platform (2), are then provided on the movable plate (56).
  • the previous embodiments can thus be adapted to this variant by replacing the upper face (8) of the loading platform (2) with the upper face (57) of the movable plate (56).
  • the movable plate (56) has a recess (58) intended to be able to be superposed above a recess (6) provided in the loading platform (2) at the level of the location provided for the wheels (4) of the road vehicle (3).
  • the recess (58) of the movable plate (56) may have dimensions similar to those of the recess (6) arranged in the loading platform (2), or have different dimensions, as long as these allow the at least partial engagement of a wheel (4) through the recess (58).
  • the movable plate (56) is in the form of a rigid and flat support piece (59) which is slidably mounted on the loading platform (2), for example by engagement of its lateral edges in a housing provided in longitudinal rails (60) provided on the loading platform (2).
  • the support device (9) may comprise a locking device making it possible to lock the movable plate (56) in position relative to the loading platform (2).
  • the locking of the movable plate (56) with respect to the loading platform (2) is thus achieved by means of a transverse locking pin (62) which engages in a releasable manner in one of the indentations (61) provided in the side edges of the movable plate (56).
  • a transverse locking pin (62) which engages in a releasable manner in one of the indentations (61) provided in the side edges of the movable plate (56).
  • step c) the positioning of at least one support device (9) on the loading platform (2) is preferably carried out manually.
  • step f) the loading of the road vehicle (3) on the loading platform (2) is carried out either from above by means of a crane, a gantry or any other lifting means, or by rolling the road vehicle (3) by its wheels (4) on the loading platform (2).
  • the bogies (7) of the railway wagon (1) are not worn and the road vehicle (3) is light, so the loading platform (2) is not lowered.
  • light it is meant here that the road vehicle (3) has a negligible weight compared to the maximum weight that the loading platform (2) can support.
  • a semi-trailer it is for example an empty semi-trailer or one carrying a very light load. Since the board of load (2) is not lowered, it is at the highest point and the road vehicle (3) must be placed as low as possible in order to respect the railway gauge, i.e.
  • each support piece (10) is adjusted so as to allow the lower part of the wheels (4) of the road vehicle (3) to penetrate below the level of the upper face (8 ) of the loading platform (2), while supporting the wheels (4) of the road vehicle (3) and immobilizing them longitudinally.
  • the bogies (7) of the railway wagon (1) are new and the road vehicle (3) is heavy, so the loading platform (2) is lowered because the weight of the load causes the loading platform (2) to deflect. Since the lowest point of the loading platform (2) is lowered, the road vehicle (3) must be raised relative to the previous situation in order to respect the rail gauge. Thanks to the position or the conformation of each support piece (10) the height adjustment of the wheels can be very precise in order to adjust the position of the road vehicle (3) downwards by the desired height.
  • the bogies (7) of the railway wagon (1) are worn and the road vehicle (3) is heavy, in particular in the case of a semi-trailer transporting a very heavy load. It is the weight of the load carried by the loading plate (2) which causes it to bend, and the loading plate (2) is further lowered because the diameter of the wheels of the bogies (7) is reduced compared to those of a new bogie (18). Thus, in its bent part corresponding to its lowest point, the loading plate (2) is very low and is at the lower limit allowed. Here too the road vehicle (3) must be raised relative to the previous situation in order to respect the rail gauge.
  • the road vehicle (3) is raised so that its wheels (4) rest substantially at the same height as if they were resting on a conventional loading platform (2) with no recess (6).
  • the position or conformation of each support piece (10) is then adjusted so that the wheels (4) of the road vehicle (3) are at the level of the upper face of the loading platform (2) while immobilizing them longitudinally .
  • a pocket-type loading platform (2) is provided to be suspended longitudinally between two end elements (45) of the railway wagon (1) which include the bogies (7) or to be suspended laterally between two side members (46) of the railway wagon (1), as shown by way of example in the figure 9 .
  • the road vehicle (3) loaded on a loading platform (2) of the pocket type is represented on the figures 6 to 8 , before this assembly is loaded onto a railway wagon (1).
  • the wheels (4) of the road vehicle (3) can freely protrude below the pocket-type loading platform (2), since they enter the recesses (6) provided for this purpose in the loading platform (2) and can freely protrude below the loading platform (2).
