Abstract

The invention concerns a railway unit (1) consisting of two end running assemblies (5) and (6) interconnected by a pivoting support railway structure (10) detachable to take up an oblique loading and unloading position. The invention is characterised in that the pivoting support railway structure (10) comprises at least at one of its ends (5) and (6) lockable support and bearing means (16) mobile between two positions, said means (16) being designed to lock the rear axle wheels of the second tractor (4) transported with a first tractor (3) in the place of a semi-trailer on the same railway unit and bring it into a lifted transporting position. The invention is of interest to manufacturers of railway equipment for combined rail/road transport.

Description

L'invention se rapporte à une unité ferroviaire de transport combiné rail/route à structure porteuse pivotante dissociable au moins par une de ses extrémités des blocs d'extrémité en vue d'occuper une position oblique de chargement et de déchargement.The invention relates to a unit combined rail / road transport rail to pivoting support structure which can be separated at least by one of its ends in view of the end blocks occupy an oblique loading position and unloading.

L'invention se rapporte plus particulièrement à une telle structure ferroviaire porteuse pivotante équipée d'un support basculant permettant de charger, de transporter puis de décharger aussi bien deux véhicules à moteur qu'une semi-remorque sur la même unité ferroviaire et ceci sans modification de celle-ci.The invention relates more particularly to such a pivoting load-bearing railway structure equipped with a tilting support allowing to charge, to transport and then unload two as well motor vehicles as a semi-trailer on the same railway unit and this without modification thereof.

La technique la moins lourde en équipement dans le mode de transport combiné rail/route des semi-remorques utilise le tracteur pour charger la semi-remorque sur la structure ferroviaire porteuse.The lightest technique in equipment in the combined rail / road transport mode of semi-trailers uses the tractor to load the semi-trailer on the supporting railway structure.

Celle-ci se dégage du wagon en oblique selon une position de chargement et de déchargement dans laquelle la semi-remorque est amenée ou enlevée par son tracteur.This emerges from the wagon obliquely according to a loading and unloading position in which the semi-trailer is brought in or taken out by his tractor.

Pour des raisons d'encombrement et de logistique, le tracteur est désaccouplé de la semi-remorque après chargement et reste sur place ou voyage séparément sur le même train de transport combiné rail/route.For reasons of space and logistics, the tractor is uncoupled from the semi-trailer after loading and stays on site or travels separately on the same combined transport train rail / road.

Bien que techniquement compatibles avec d'autres tracteurs de semi-remorques, les semi-remorques à transporter par le rail, n'appartiennent pas toujours à de grandes entreprises largement pourvues en tracteurs sur le lieu de destination.Although technically compatible with other tractor-trailers, semi-trailers to be transported by rail, do not belong not always to large companies widely provided with tractors at the place of destination.

Pour cette raison et pour de simples impératifs économiques, il s'avère avantageux de transporter le tracteur affecté à la semi-remorque dans le même train.For this reason and for simple economic imperatives, it turns out to be advantageous to transport the tractor assigned to the semi-trailer on the same train.

De plus, dans certain cas, seule une fraction du trajet total s'effectuera par l'intermédiaire de ces trains. Le tracteur doit sur cette partie voyager obligatoirement avec sa semi-remorque.In addition, in some cases, only a fraction of the total journey will be made through these trains. The tractor must travel on this part necessarily with his semi-trailer.

La nouvelle technique dans laquelle s'inscrit l'invention ne comporte que des unités ferroviaires prédestinées au transport des semi-remorques. Pour des raisons économiques, techniques et réglementaires, ces unités ferroviaires ne présentent qu'une longueur limitée. Leur conformation est telle que le porte-à-faux avant des semi-remorques surplombe un des blocs roulants d'extrémité de l'unité ferroviaire. De ce fait, la capacité de chargement de ces unités ferroviaires est prévue au plus juste pour le transport d'une semi-remorque chacun. Ainsi, deux tracteurs de semi-remorque dépasseraient en longueur celle du fond porteur de la structure ferroviaire porteuse pivotante et ne pourraient donc être transportés simultanément dans ce type de wagon. Lorsque des tracteurs routiers de semi-remorques doivent être transportés dans ces wagons, on ne peut en transporter qu'un à la fois.The new technique in which fits the invention only comprises railway units predestined for the transport of semi-trailers. For some economic, technical and regulatory reasons, these rail units are only one length limited. Their conformation is such that the overhang front of the semi-trailers overhangs one of the blocks end of the rail unit. From this fact, the loading capacity of these units rail is planned for the fairest for the transport of a semi-trailer each. So two semitrailer tractors would protrude in length that of the supporting bottom of the railway structure pivoting carrier and therefore could not be transported simultaneously in this type of wagon. When tractor-trailers of semi-trailers must be transported in these cars, you cannot carry only one at a time.

Cette solution est en tout point anti-économique. Elle est contraire à l'optimisation logistique des rames et des unités ferroviaires.This solution is completely uneconomic. It is against optimization trainsets and railway units logistics.

Le tracteur peut aussi être transporté dans une autre partie du train composée de wagons spéciaux destinés à recevoir les tracteurs. Cette organisation n'est pas non plus satisfaisante en raison de la disparité des unités ferroviaires et des convois ferroviaires à gérer.The tractor can also be transported in another part of the train made up of special wagons intended to receive tractors. This organization is also unsatisfactory due to the disparity of railway units and convoys railway to manage.

De plus, l'éloignement entre le tracteur et sa semi-remorque représente une perte de temps et d'énergie importante dans les phases de chargement et de déchargement. In addition, the distance between the tractor and his semi-trailer is a waste of time and significant energy in the loading phases and unloading.

Cet éloignement peut compliquer notablement la reconstitution des ensembles routiers articulés au terminal d'arrivée.This distance can significantly complicate the reconstitution of articulated road units in arrival terminal.

La présente invention a pour but de permettre de charger, de décharger et de transporter alternativement aussi bien deux tracteurs routiers de semi-remorque qu'une semi-remorque sur une même unité ferroviaire de transport combiné rail/route prédestinée au transport d'une semi-remorque.The present invention aims to allow load, unload and transport alternately as well two road tractors from semi-trailer than a semi-trailer on the same unit railway combined rail / road transport intended for the transport of a semi-trailer.

Elle a pour but également de faciliter le chargement et le déchargement des deux types de charges routières en faisant remplir au support basculant lorsqu'il est au sol, la fonction de repère pour le tracteur en vue du positionnement précis de la charge routière qu'il amène ou pour le positionnement du tracteur en position de chargement lorsque celui-ci constitue lui même la charge routière.It also aims to facilitate the loading and unloading of the two types of road loads by having the support fill tilting when it is on the ground, the benchmark function for the tractor for the precise positioning of the road load it brings or for positioning of the tractor in the loading position when the latter itself constitutes the road load.

Ce positionnement doit notamment permettre d'éliminer tout risque d'interférence avec l'unité ferroviaire lors de sa remise en ligne.This positioning must in particular allow eliminate any risk of interference with the unit rail when it is brought back online.

L'invention a pour but également de permettre de s'assurer lors du chargement d'une semi-remorque qu'elle est bien en position et ceci avant le pivotement de fermeture de l'unité ferroviaire.The invention also aims to allow ensure when loading a semi-trailer it is in position and this before the rail unit closing pivot.

Grâce à l'invention, des unités ferroviaires porteuses ou des sous-ensembles ferroviaires porteurs prédestinés au transport chacun d'une semi-remorque faisant partie d'un même ensemble ferroviaire articulé peuvent recevoir et transporter chacun deux véhicules à moteur, notamment deux tracteurs de semi-remorque et ceci sur la même base de transport ferroviaire que celle pouvant recevoir une semi-remorque.Thanks to the invention, railway units load-bearing or load-bearing railway sub-assemblies predestined for transport each of a semi-trailer being part of the same articulated railway set can each receive and transport two vehicles powered, including two tractor-trailer tractors and this on the same basis of rail transport as that which can receive a semi-trailer.

Ces unités de transport ferroviaire rail/route deviennent ainsi bivalentes dans leur utilisation simplifiant la gestion des configurations ferroviaires et facilitant celle de leur disponibilité, la composition des trains et les phases de chargement et de déchargement.These rail transport units rail / road thus become bivalent in their use simplifying configuration management and facilitating that of their availability, train composition and phases loading and unloading.

Plus particulièrement, chaque unité ferroviaire qu'elle soit indépendante ou faisant partie d'un ensemble articulé présente une structure ferroviaire porteuse pouvant recevoir une semi-remorque, mais aussi, au choix, deux tracteurs disposés à la suite l'un de l'autre et ceci sans difficulté technique particulière d'utilisation et sans nécessiter l'emploi d'unités dédiées au transport de véhicules à moteur.More specifically, each unit whether independent or doing part of an articulated assembly has a structure carrier rail that can accommodate a semi-trailer, but also, as desired, two tractors arranged one after the other and this without particular technical difficulty of use and without requiring the use of dedicated transport units motor vehicles.

La gestion du matériel, et la logistique du transport combiné rail/route mais aussi celle de l'ensemble du transport d'une charge routière donnée s'en trouvent nettement améliorées.Material management and logistics combined rail / road transport but also that of the entire transport of a given road load are significantly improved.

De plus, grâce à l'invention, les opérations de chargement et de déchargement sont rendues plus rapides, plus faciles et plus précises à la fois et donc plus sécuritaires.In addition, thanks to the invention, the operations loading and unloading are made more faster, easier and more precise at the same time and therefore safer.

La principale caractéristique de l'invention concerne un support basculant de réception et de relevage prévu à l'une des extrémités de la structure ferroviaire porteuse destiné à recevoir les roues du train arrière du tracteur placé à cette extrémité et de l'incliner suffisamment pour permettre le transport de deux tracteurs.The main feature of the invention concerns a tilting support for receiving and lifting provided at one end of the structure carrier rail intended to receive the wheels of the rear axle of the tractor placed at this end and tilt it enough to allow transportation of two tractors.

La sécurité en débattement du pivot de sellette de la semi-remorque est assurée par un organe indépendant prévu sur la structure d'extrémité de l'unité ferroviaire ou par un dispositif intégré au support basculant de support et de levage et se déplaçant donc avec lui.Safety in travel of the pivot of fifth wheel of the semi-trailer is provided by a body independent provided on the end structure of the rail unit or by a device integrated into the tilting support and lifting support and therefore moving with him.

L'invention se rapporte à une unité ferroviaire 1 du type wagon à utiliser dans le cadre du transport combiné rail/route pour le transport au choix d'une semi-remorque 2 ou de deux véhicules routiers à moteur plus particulièrement du type tracteur 3 ou 4 d'une semi-remorque.The invention relates to a railway unit 1 of the wagon type to be used for transport combined rail / road for transport of your choice semi-trailer 2 or two road motor vehicles more particularly of the tractor type 3 or 4 of a semi-trailer.

L'unité de transport ferroviaire 1 peut être de tous les types à partir du moment où elle vient se placer en position oblique par rapport à la voie pour les opérations de chargement et de déchargement.The rail transport unit 1 can be all types from the time it comes get place obliquely to the track to loading and unloading operations.

Elle peut être placée et individualisée entre deux ensembles roulants d'extrémité 5 ou 6 comportant un ou plusieurs essieu(x) 7 ou 8 ou faire partie d'un ensemble articulé de transport combiné rail/route, par exemple un wagon double 9 comme représenté sur les figures 1 et 3.It can be placed and individualized between two end rollers 5 or 6 comprising one or more axle (s) 7 or 8 or be part of a articulated combined transport rail / road, by example a double 9 wagon as shown in the Figures 1 and 3.

Cette unité ferroviaire 1 de transport ferroviaire combiné rail/route est du type à structure ferroviaire 10 portant une charge routière plus particulièrement une semi-remorque 2 et montée pivotante par exemple autour d'un axe central ou décalé en vue de réaliser les phases de chargement et de déchargement dans une position oblique par rapport à l'axe longitudinal du wagon.This rail transport unit 1 combined rail / road rail is structural type rail 10 carrying a road load more particularly a semi-trailer 2 and mounted pivoting for example around a central axis or shifted in order to carry out the loading phases and unloading in an oblique position relative to the longitudinal axis of the wagon.

Il a été trouvé conformément à l'invention que cette structure ferroviaire porteuse 10 d'une charge routière pouvait par divers aménagements et équipements compatibles avec le maintien de sa fonction d'origine de transport d'une semi-remorque 2, transporter deux véhicules à moteur, par exemple deux tracteurs 3 et 4 pour semi-remorques, procurant ainsi à ce type d'unité ferroviaire 1 par exemple de wagon une fonction de mixité d'utilisation relative à la nature de la charge routière transportée.It was found in accordance with the invention that this carrying railway structure 10 of a road load could by various amenities and equipment compatible with maintaining its original transport function of a semi-trailer 2, transport two motor vehicles, for example two tractors 3 and 4 for semi-trailers, providing to this type of rail unit 1 for example of wagon a mixed use function relating to the nature of the road load transported.

L'unité de transport ferroviaire 1 selon l'invention déjà décrite dans des dépôts antérieurs du même déposant se compose selon un exemple de réalisation des organes principaux suivants.Rail transport unit 1 according to the invention already described in previous filings of the same depositor is composed according to an example of realization of the following main organs.

Une structure ferroviaire porteuse 10 de la charge routière repose par ses extrémités 11 et 12 sur deux ensembles roulants d'extrémité 5 et 6 à un ou plusieurs essieux tels que 7 et 8.A railway structure carrying 10 of the road load rests at its ends 11 and 12 on two end wheel sets 5 and 6 at one or several axles such as 7 and 8.

Elle est montée pivotante par exemple autour d'un axe central ou excentré ou décalé jusqu'à l'une de ses extrémités ou peut relever d'autres formes de réalisation comportant d'autres moyens de mise en oblique.It is pivotally mounted, for example around from a central or eccentric or offset axis to one of its ends or may fall under other forms of realization comprising other means of setting oblique.

Elle présente selon le cas lors de l'ouverture de pivotement soit une seule soit deux extrémités d'accès l'une avant 11 et l'autre arrière 12.It presents as the case may be during the pivot opening either one or two access ends one front 11 and the other rear 12.

La structure ferroviaire porteuse 10 se détache par au moins une de ses extrémités 11 ou 12 d'au moins un ensemble roulant d'extrémité 5 ou 6 avec lequel elle est assemblée par des moyens d'assemblage et de verrouillage dissociables 13 ou 14.The supporting railway structure 10 is detaches by at least one of its ends 11 or 12 at least one end rolling assembly 5 or 6 with which it is assembled by means of assembly and separable lock 13 or 14.

La dissociation s'effectue préférentiellement par un mouvement de levage suivi d'un mouvement de pivotement en oblique par rapport à l'axe longitudinal de l'unité ferroviaire 1 au moyen par exemple d'un dispositif motorisé de levage-pivotement jusqu'à une position oblique de chargement et de déchargement dans laquelle au moins une extrémité d'accès 11 ou 12 de la structure ferroviaire porteuse 10 touche le sol du quai ou un autre dispositif motorisé de pivotement intégré dans le quai ou rapporté sur celui-ci, par exemple une base ou une rampe d'accès 15 ou autre structure intermédiaire de liaison ou de franchissement.The dissociation is preferably carried out by a lifting movement followed by a movement of tilting obliquely to the longitudinal axis of the rail unit 1 by means for example of a motorized lifting-pivoting device up to oblique loading and unloading position in which at least one access end 11 or 12 of the load-bearing railway structure 10 touches the ground of the dock or other motorized slewing device integrated into the platform or attached to it, by example a base or an access ramp 15 or other intermediate structure of connection or crossing.

Ces structures ferroviaires porteuses 10 sont destinées à transporter des charges routières automotrices ou apportées sur celles-ci par leurs propres moyens moteurs routiers dissociables de la charge routière.These load-bearing railway structures 10 are intended for transporting road loads self-propelled or brought thereon by their own road engines separable from the road load.

Un exemple courant est celui d'une semi-remorque 2 qui accède à l'intérieur de cette structure ferroviaire porteuse 10 par son tracteur routier 3 ou 4 qui la pousse ou la tracte lors des manoeuvres.A common example is that of a semi-trailer 2 which accesses the interior of this structure carrier rail 10 by its road tractor 3 or 4 which pushes or pulls it during the maneuvers.

Un dispositif de limitation du débattement du pivot de sellette en cours de transport faisant l'objet d'une protection parallèle peut être prévu sur au moins un des ensembles roulants d'extrémité 5 ou 6.A device for limiting the travel of the fifth wheel pivot during transport the subject of parallel protection may be provided on at least one of the end rolling assemblies 5 or 6.

La présente invention a pour but de perfectionner ces unités ferroviaires 1 destinées en particulier à transporter des semi-remorques 2 pour leur permettre de recevoir au choix à titre de charge routière à transporter, deux véhicules à moteur et plus particulièrement deux tracteurs routiers 3 et 4 du type de ceux associés aux semi-remorques 2. Ces tracteurs 3 et 4 disposés l'un à la suite de l'autre sur le fond de la structure ferroviaire pivotante 10 ne rentreraient pas sur la surface porteuse de cette structure ferroviaire pivotante 10. Conformément à l'invention, l'un des tracteurs 4 est relevé pour gagner en longueur totale de chargement et permettre ainsi le transport de deux tracteurs 3 et 4 de semi-remorque 2 placés l'un à la suite de l'autre.The object of the present invention is to perfect these railway units 1 intended for particular to transport semi-trailers 2 for allow them to receive as a charge road to transport, two motor vehicles and more particularly two road tractors 3 and 4 of the type associated with semi-trailers 2. These tractors 3 and 4 arranged one after the other on the bottom of the pivoting rail structure 10 would not enter the load-bearing surface of this pivoting rail structure 10. In accordance with the invention, one of the tractors 4 is raised to gain in total loading length and allow thus the transport of two semi-trailer tractors 3 and 4 2 placed one after the other.

Pour ce faire et conformément à l'invention, la structure ferroviaire porteuse et pivotante 10 est équipée au moins à l'une de ses extrémités 11 ou 12 d'un moyen 16 verrouillable de support ou de soutien mobile entre deux positions, l'une de chargement et de déchargement, et l'autre de transport avec une fonction de calage de la charge, ce moyen servant aussi bien dans le cas du transport d'une semi-remorque 2 que dans le cas du transport de deux tracteurs 3 et 4 de semi-remorque.To do this and in accordance with the invention, the supporting and pivoting rail structure 10 is fitted at least at one of its ends 11 or 12 a lockable support or support means 16 movable between two positions, one for loading and unloading, and the other transport with a load setting function, this means serving both in the case of transporting a semi-trailer 2 that in the case of the transport of two semi-trailer tractors 3 and 4.

Ce moyen 16, par exemple réalisé sous la forme d'un support basculant 17, permet de lever suffisamment l'arrière du deuxième tracteur 4 pour arriver à loger les deux tracteurs 3 et 4 sur la même unité ferroviaire 1 prédestinée au transport d'une semi-remorque 2 et ceci grâce à la position relevée de l'arrière du tracteur 4 au-dessus d'une partie de l'ensemble roulant d'extrémité correspondant 5 ou 6.This means 16, for example produced under the form of a tilting support 17, allows lifting sufficiently behind the second tractor 4 to manage to accommodate the two tractors 3 and 4 on the same rail unit 1 predestined for the transport of semi-trailer 2 thanks to the raised position of rear of tractor 4 over part of the corresponding end rolling assembly 5 or 6.

Il permet également lors de la remise en ligne droite de la structure ferroviaire porteuse pivotante 10 d'éviter toute interférence entre la charge routière et les ensembles d'extrémité 5 ou 6.It also allows when refitting straight line of the supporting railway structure swivel 10 to avoid any interference between the road load and end assemblies 5 or 6.

Il permet aussi de servir de démarquer la position de la semi-remorque ou d'un autre véhicule lors de l'engagement sur l'unité ferroviaire jouant ainsi le rôle d'un moyen de repérage. Ce support basculant 17 est actionné par exemple par des moyens extérieurs du type vérins ou autres non embarqués faisant partie par exemple d'une installation à quai telle que la base de chargement ou la rampe d'accès 15 ou toute autre moyen équivalent.It also serves to distinguish the position of the semi-trailer or other vehicle during the engagement on the railway unit playing thus the role of a means of location. This support tilting 17 is actuated for example by means cylinders or other types not on board forming part for example of a dockside installation such as the charging base or the access ramp 15 or any other equivalent means.

On peut envisager d'embarquer les moyens de levage et l'énergie correspondante.We can consider embarking the means of lifting and the corresponding energy.

Comme indiqué, ce support basculant 17 sert aussi de repère de positionnement de la charge routière lors de sa mise en place pendant les phases de chargement.As indicated, this tilting support 17 serves also load positioning marker road during its installation during the phases loading.

On décrira ci-après en détail la variante de base de l'unité ferroviaire 1 selon l'invention.The variant of base of the rail unit 1 according to the invention.

La structure ferroviaire porteuse pivotante 10 comporte au moins à l'une de ses extrémités d'accès 11 ou 12 un moyen de support ou de soutien 16 sous la forme d'un support basculant 17 monté articulé, par exemple pivotant sur la structure ferroviaire porteuse pivotante 10 par exemple sur chacun des longerons de bordure longeant la partie supérieure de ses pièces de flanc.The pivoting load-bearing railway structure 10 has at least one of its access ends 11 or 12 a means of support or support 16 under the form of a tilting support 17 mounted articulated, by example pivoting on the supporting railway structure pivoting 10 for example on each of the side members of border along the upper part of its pieces of flank.

Pour des raisons de simplicité, les axes de pivotement sont dessinés schématiquement par leur représentation géométrique.For reasons of simplicity, the axes of pivot are drawn schematically by their geometric representation.

Le support basculant 17 est formé de deux bras pivotants 18 et 19 montés à pivotement par une de leurs extrémités autour d'un axe perpendiculaire à l'axe longitudinal de la structure ferroviaire porteuse pivotante 10 portés par exemple par les bordures supérieures des pièces de flanc de celle-ci. Ces bras 18 et 19 portent de façon pendulaire ou non, à la manière d'une nacelle, c'est-à-dire autour d'axes d'extrémité 20 et 21 perpendiculaires aux bras 18 et 19 ou autrement, une structure transversale par exemple d'appui 22 continue ou discontinue.The tilting support 17 is formed of two swivel arms 18 and 19 pivotally mounted by one of their ends around an axis perpendicular to the longitudinal axis of the railway structure pivoting carrier 10 carried for example by upper edges of the side pieces thereof. These arms 18 and 19 carry pendulum or not, in the manner of a nacelle, that is to say around axes end 20 and 21 perpendicular to the arms 18 and 19 or otherwise, a transverse structure by example of support 22 continuous or discontinuous.

Comme on le verra ci-après, la structure transversale 22 n'est pas forcément porteuse.As will be seen below, the structure transverse 22 is not necessarily load-bearing.

Les bras pivotants 18 et 19 sont immobilisés en position relevée de soutien par un dispositif de verrouillage (non représenté).The pivoting arms 18 and 19 are immobilized in the raised support position by a locking (not shown).

Dans le cas d'une structure continue les deux bras 18 et 19 sont reliés mécaniquement entre eux par une structure transversale d'appui continue 22.In the case of a continuous structure both arms 18 and 19 are mechanically linked together by a transverse continuous support structure 22.

Dans le cas d'une structure discontinue, il s'agit de deux supports pivotants séparés qui s'étendent vers l'intérieur, leur longueur étant suffisante pour retenir au moins une des roues de chaque côté du train arrière du tracteur transporté en position relevée(variante non représentée).In the case of a discontinuous structure, it these are two separate swivel brackets which extend inward, their length being sufficient to retain at least one of the each side of the rear axle of the tractor transported in raised position (variant not shown).

La structure transversale d'appui continue 22 est formée de deux éléments transversaux 23 et 24, par exemple tubulaires, parallèles entre eux avec rapprochement au centre et liaison par une platine porteuse et de retenue 25 sous la forme de deux plaques parallèles 26 et 27 définissant une ouverture centrale ou cavité 28 de réception et éventuellement de maintien délimitée par un périmètre de retenue 29 pour la cheville ouvrière ou pivot 30 de la semi-remorque transportée 2.The transverse support structure continues 22 is formed by two transverse elements 23 and 24, by tubular example, parallel to each other with approximation to the center and connection by a plate load-bearing and retaining 25 in the form of two parallel plates 26 and 27 defining an opening central or receiving cavity 28 and possibly of maintenance delimited by a perimeter of retention 29 for the kingpin or pivot 30 of the semi-trailer transported 2.

La cavité 28 assure notamment un maintien et une immobilisation de la charge par rapport aux efforts latéraux.The cavity 28 provides in particular a maintenance and immobilization of the load in relation to lateral forces.

Les éléments tubulaires transversaux 23 et 24 sont écartés de telle façon dans la zone adjacente aux bords de la structure ferroviaire porteuse 10 qu'ils forment entre eux de chaque côté une ouverture de réception et de butée 31 et 32 dans chacune desquelles s'enfonce et vient se caler la roue arrière 33 ou 34 correspondante du train arrière 35 du tracteur 4 transporté en position relevée. Lorsque les deux roues arrière 33 et 34 sont engagées dans leur ouverture de butée correspondante 31 et 32, l'ensemble arrière du tracteur 4 est suffisamment immobilisé par calage pour être relevé et tenir stable en position de transport.The transverse tubular elements 23 and 24 are spread in such a way in the area adjacent to edges of the load-bearing railway structure 10 they form an opening between them on each side reception and stop 31 and 32 in each of which sinks and comes to stall the rear wheel 33 or 34 rear axle 35 of tractor 4 transported in the raised position. When the two wheels rear 33 and 34 are engaged in their opening of corresponding stop 31 and 32, the rear assembly of the tractor 4 is sufficiently immobilized by chocking to be raised and held stable in the transport position.

Cette structure transversale d'appui 22 sert dans les deux cas principaux de charge routière envisagée, à savoir pour le transport d'une semi-remorque 2 d'une part, et pour le transport de deux tracteurs 3 et 4 de semi-remorque 2 d'autre part.This transverse support structure 22 serves in the two main cases of road load envisaged, namely for the transport of a semi-trailer 2 on the one hand, and for the transport of two tractors 3 and 4 of semi-trailer 2 on the other hand.

Dans le premier cas, la structure transversale d'appui 22 du support basculant 17 vient s'appliquer au centre de la sous-face avant 36 de semi-remorque sous l'effet de moyens moteurs par exemple extérieurs à l'unité ferroviaire 1 réalisant ainsi un calage primaire à l'avant de préférence en combinaison avec celui conféré par les béquilles 37 et 38 de la semi-remorque 2. Lorsque chacune des roues arrière 33 et 34 du tracteur 4 se trouve entre les éléments transversaux 23 et 24 de la structure transversale d'appui 22, la ligne transversale à la semi-remorque 2 passant par le pivot 30 de sellette passe par l'arc de cercle 39 décrit par l'extrémité de chacun des bras 18 et 19 du support basculant 17 ce qui montre son rôle de repère lors des opérations d'amenée de la semi-remorque 2 dans la structure ferroviaire porteuse pivotante 10 lorsqu'elle se trouve au sol comme le montre la figure 17.In the first case, the structure transverse support 22 of the tilting support 17 comes apply to the center of the front sub-face 36 of semi-trailer under the effect of motor means by example outside rail unit 1 realizing thus a primary setting at the front preferably in combination with that provided by crutches 37 and 38 of the semi-trailer 2. When each of the wheels rear 33 and 34 of tractor 4 is between transverse elements 23 and 24 of the structure transverse support 22, the line transverse to the semi-trailer 2 passing through the pivot 30 of the fifth wheel goes through the arc 39 described by the end of each of the arms 18 and 19 of the tilting support 17 ce which shows its role as a benchmark during operations of the semi-trailer 2 into the structure pivoting carrier rail 10 when found on the ground as shown in Figure 17.

Selon une variante, une fois la semi-remorque 2 calée, on peut soulager les béquilles 37 et 38 puisque la structure transversale d'appui 22 arrive en appui de butée ou de soutien sur la sous-face avant 36 de la semi-remorque 2.Alternatively, once the semi-trailer 2 wedged, we can relieve crutches 37 and 38 since the transverse support structure 22 arrives at stop or support support on the front sub-face 36 of the semi-trailer 2.

Selon une autre variante, les béquilles 37 et 38 assurent principalement le soutien de la semi-remorque ainsi la platine porteuse 25 n'apporte qu'un soutien partiel voire faible.According to another variant, the crutches 37 and 38 mainly support the semi-trailer thus the carrier plate 25 provides only partial or even weak support.

Afin de faciliter les opérations de chargement de la semi-remorque 2, on prévoit dans le cadre de l'invention que le fond de la structure ferroviaire porteuse pivotante 10 présente en deça de la zone où se trouvent les béquilles de la semi-remorque en position de transport ou en avant des béquilles, une marche ou un rehaussement 39 de son plancher dont la surface supérieure sert d'appui à la partie postérieure de la sous face avant 36 de la semi-remorque 2 et ceci pour se dispenser de rabattre les béquilles en sortie puis en rentrée lors du chargement et du déchargement et éventuellement lors du transport. Ce rehaussement assure aussi un calage. Il est visible sur la figure 7.In order to facilitate the operations of loading of semi-trailer 2, framework of the invention that the bottom of the structure pivoting carrier rail 10 present below the area where the stands of the semi-trailer are located in transport position or in front of crutches, a step or a sound enhancement 39 floor whose upper surface is used to support the posterior part of the front underside 36 of the semi-trailer 2 and this to avoid folding down the crutches out and then back in when loading and unloading and possibly during of transportation. This enhancement also ensures timing. It is visible in Figure 7.

Dans le deuxième cas, le deuxième tracteur 4 vient se placer après roulage sur la rampe ou la base d'accès 15 dont un exemple a été représenté sur les figures 7 à 9 de telle façon que chacune de ses roues arrière 33 et 34 vienne se placer entre les éléments transversaux tubulaires 23 et 24 de la structure transversale d'appui 22. Celle-ci est ensuite basculée vers le haut, mouvement au cours duquel les éléments transversaux tubulaires 23 et 24 remontent le long des roues arrière 33 et 34 dans l'ouverture de calage de ces roues jusqu'à une profondeur de calage prédéfinie par l'écartement d'extrémité des éléments transversaux 23 et 24.In the second case, the second tractor 4 is placed after rolling on the ramp or base access 15 of which an example has been shown on the Figures 7 to 9 so that each of its wheels rear 33 and 34 is placed between the elements tubular cross sections 23 and 24 of the structure transverse support 22. This is then tilted upward movement in which the elements transverse tubulars 23 and 24 go up along the rear wheels 33 and 34 in the chock opening of these wheels up to a predefined chock depth by the end spacing of the transverse elements 23 and 24.

Comme indiqué, la structure transversale d'appui 22 peut être discontinue. Elle affecte alors de chaque côté la forme de deux bouts de tube portés par les extrémités des bras et destinés à recevoir comme précédemment les roues arrière 33 et 34 du tracteur 4. Ces bouts de tube présentent chacun une extrémité libre ou qui se trouve réunie à son homologue par un tube de fermeture afin de former une ouverture à périmètre délimité créant ainsi ce que l'on appelle un panier (variante non représentée).As shown, the transverse structure support 22 may be discontinuous. It then affects on each side the shape of two ends of tube carried by the ends of the arms and intended to receive as before the rear wheels 33 and 34 of the tractor 4. These ends of the tube each have a free end or which is joined to its homologated by a closure tube in order to form a opening at defined perimeter thus creating what a basket is called (variant not shown).

Le principe d'immobilisation des roues arrière du tracteur reste identique. En début de relevage, la structure transversale d'appui vient caler les roues arrière 33 et 34 du tracteur 4 et procure une immobilisation suffisante pour le transport.The principle of immobilization of the wheels rear of the tractor remains the same. At the beginning of lifting, the transverse support structure comes chock the rear wheels 33 and 34 of the tractor 4 and provides sufficient immobilization for the transport.

La poursuite du mouvement de basculement en levage entraíne l'arrière du tracteur 4 vers le haut jusqu'à sa position relevée de transport.The continuation of the tilting movement in lifting drives the rear of the tractor 4 upwards to its raised transport position.

Il faut bien noter que le fait de faire basculer l'arrière du tracteur 4 vers le haut permet de le mettre dans une position suffisamment inclinée descendante vers la cabine pour qu'il n'interfère pas lors de la remise en ligne de la structure ferroviaire porteuse 10 avec les structures supérieures de l'ensemble d'extrémité correspondant 5 ou 6 de cette unité ferroviaire 1 représentant une conformation plus élevée que le niveau du fond de la structure ferroviaire porteuse pivotante 10 sur lequel repose les roues avant du tracteur 4.It should be noted that doing tilting the rear of the tractor 4 up allows to put it in a sufficiently inclined position descending towards the cabin so that it does not interfere when the railway structure is brought back online carrier 10 with the upper structures of the corresponding end assembly 5 or 6 of this rail unit 1 representing a more conformation high than the level of the bottom of the structure pivoting carrier rail 10 on which rests tractor front wheels 4.

L'avant de la semi-remorque 2 n'interfère pas naturellement avec ces structures supérieures des ensembles d'extrémité 5 ou 6 en raison de la hauteur par rapport au sol de l'avant de son châssis diminuée de la cheville ouvrière ou pivot 30 et de l'épaisseur de la structure transversale d'appui 22.Front of semi-trailer 2 does not interfere naturally with these higher structures of end sets 5 or 6 due to height compared to the ground of the front of its chassis reduced of the kingpin or pivot 30 and the thickness of the transverse support structure 22.

Il faut bien noter ici l'importance de ce support basculant 17 au moment du chargement et du déchargement.It should be noted here the importance of this tilting support 17 at the time of loading and unloading.

La structure transversale d'appui 22 du support basculant 17 repose sur le sol du quai ou sur une rampe ou une base d'accès 15 de quai souvent utilisée lors des chargements et déchargements à quai pendant la manoeuvre d'accès.The transverse support structure 22 of the tilting support 17 rests on the platform floor or on a ramp or access platform 15 often used during loading and unloading at quay during the access maneuver.

Lors de la manoeuvre d'amenée de la semi-remorque 2 qui s'effectue soit en marche arrière soit en marche avant, les roues arrière 33 et 34 du tracteur 3 ou 4 vont franchir le premier élément tubulaire 23 en provoquant un débattement des suspensions perçu et facilement identifiable par le conducteur. Il s'agit d'un signal de repérage en position. Le conducteur sait que la semi-remorque 2 arrive à la bonne position de calage et de transport.When maneuvering the semi-trailer 2 which is carried out either in reverse or in forward gear, the rear wheels 33 and 34 of the tractor 3 or 4 will cross the first element tubular 23 causing a deflection of the suspensions perceived and easily identifiable by the driver. This is a tracking signal in position. The driver knows that the semi-trailer 2 arrives at the correct stall and transport position.

De façon analogue, lorsque l'on charge le deuxième tracteur 4 en marche avant dans la structure ferroviaire pivotante, le franchissement du premier élément transversal tubulaire 23 sert de signal de repérage en position.Similarly, when loading the second tractor 4 forward in the structure swivel rail, crossing the first tubular transverse element 23 serves as a signal position marking.

La semi-remorque 2 peut ensuite être dételée et abandonnée sur ses béquilles 37 et 38 ou sur le rehaussement 39 de plancher dans la structure ferroviaire porteuse 10. Dans le cas du transport du deuxième tracteur 4, celui-ci, engagé dans l'autre sens et immobilisé dans cette position peut rester ainsi, car il se trouve dans sa position de chargement.The semi-trailer 2 can then be uncoupled and abandoned on its crutches 37 and 38 or on the raised floor 39 in the structure carrier railway 10. In the case of transport of second tractor 4, this one, engaged in the other sense and immobilized in this position can stay so because it sits in its position of loading.

On comprend tout l'intérêt supplémentaire de cette structure transversale d'appui 22 qui sert aussi de repère au sol pour la position de chargement.We understand all the additional interest of this transverse support structure 22 which also serves on the ground for the loading position.

On note un avantage supplémentaire au chargement et au déchargement des semi-remorques 2 en ce que l'ensemble basculant 17 de support et de levage permet soit de soutenir soit de soulever légèrement la semi-remorque 2 et après verrouillage des bras 18 et 19 du support basculant 17 de la caler et de la soutenir en position dès son chargement sur la structure ferroviaire porteuse 10, c'est-à-dire de la caler avant de procéder à l'assemblage de la structure ferroviaire pivotante 10 avec le ou les ensembles d'extrémité 5 ou 6 de l'unité ferroviaire 1.There is an additional advantage loading and unloading of semi-trailers 2 in what the tilting support and lifting assembly 17 allows either to support or to slightly raise the semi-trailer 2 and after locking the arms 18 and 19 of the tilting support 17 to wedge it and support in position as soon as it is loaded onto the supporting railway structure 10, that is to say of the wedge before proceeding with the assembly of the structure pivoting rail 10 with the assembly (s) end 5 or 6 of rail unit 1.

On peut ainsi vérifier l'arrimage et ensuite soulager, rétracter ou escamoter les béquilles 37 et 38 avant l'assemblage de la structure ferroviaire porteuse 10 avec les ensembles d'extrémité 5 ou 6 de l'unité ferroviaire 1. On vérifie aussi à titre complémentaire que la semi-remorque est arrêtée au bon endroit.We can check the stowage and then relieve, retract or retract the crutches 37 and 38 before assembly of the railway structure carrier 10 with end assemblies 5 or 6 of rail unit 1. We also check as that the semi-trailer is stopped correctly place.

Dans le cas d'un rehaussement 39 du plancher de la structure ferroviaire porteuse 10, on peut se dispenser de l'utilisation des béquilles.In the case of a raised floor 39 of the supporting railway structure 10, one can dispense with the use of crutches.

Bien entendu, on peut utiliser aussi les béquilles pour porter la semi-remorque dans sa position de transport.Of course, we can also use the crutches to carry the semi-trailer in its transport position.

Cette unité ferroviaire 1 de transport combiné rail/route peut également servir à transporter deux tracteurs 3 et 4 de semi-remorque ou des véhicules à moteur de longueur identique ou très voisine.This rail transport unit 1 combined rail / road can also be used to transport two semi-trailer tractors 3 and 4 or motor vehicles of identical or very long length neighbor.

Le premier véhicule à moteur par exemple le premier tracteur 3 vient s'immobiliser à plat en position de transport sur le fond et dans la partie arrière de la structure ferroviaire porteuse 10 placée en oblique pour le chargement.The first motor vehicle for example the first tractor 3 comes to a stop flat while transport position on the bottom and in the part rear of the supporting railway structure 10 placed oblique for loading.

Vient ensuite le deuxième tracteur 4 dont le train arrière 35 doit se placer au droit des zones de calage situées par exemple en continuation du plan d'accès d'une base ou rampe d'accès 15 ou de tout autre moyen équivalent rapporté sur le quai. Next comes the second tractor 4, the rear axle 35 must be positioned at the right of the wedging located for example in continuation of the plane access to a base or access ramp 15 or any other equivalent means reported on the quay.

Pour ce faire, les éléments transversaux 23 et 24 de la structure transversale d'appui 22 du support basculant 17 peuvent être légèrement encastrés dans le volume de la base ou rampe d'accès 15 ou analogue lorsque le support basculant 17 est en position basse, mais ils restent partiellement en saillie.To do this, the transverse elements 23 and 24 of the transverse support structure 22 of the tilting support 17 can be slightly recessed in the base volume or access ramp 15 or similar when the tilting support 17 is in low position, but they remain partially in projection.

Après mise en place du deuxième tracteur 4, pour que les roues 33 et 34 de son train arrière 35 viennent se caler entre les éléments transversaux 23 et 24 de la structure transversale d'appui 22, le support basculant 17 est relevé jusque dans sa position de transport c'est-à-dire celle qui permet l'assemblage de la structure porteuse pivotante avec le ou les ensemble(s) d'extrémité 5 ou 6 de l'unité ferroviaire 1 sans aucune gêne technique ni interférence.After installing the second tractor 4, so that the wheels 33 and 34 of its rear axle 35 are wedged between the transverse elements 23 and 24 of the transverse support structure 22, the tilting support 17 is raised up to its transport position, i.e. one that allows assembly of the pivoting support structure with the end assembly (s) 5 or 6 of the unit rail 1 without any technical inconvenience or interference.

Cette position inclinée de transport permet d'admettre à la place de la semi-remorque 2 et ceci dans la même unité ferroviaire 1 en tant que charge routière un ensemble formé de deux tracteurs 3 et 4 sans autre adaptation technique d'utilisation et avec une grande facilité de manoeuvre.This inclined transport position allows to admit in place of semi-trailer 2 and this in the same rail unit 1 as a load road a set formed by two tractors 3 and 4 without other technical adaptation of use and with great ease of operation.

Selon une variante, dans le cas du chargement d'une semi-remorque 2, la sous-face 36 de la partie avant du châssis est reprise par la surface centrale d'appui représentée par la platine porteuse et de retenue 25 de la structure transversale d'appui 22 du support basculant 17 pour soulager ou escamoter les béquilles 37 et 38 de la semi-remorque 2 et protéger et le cas échéant retenir le pivot 30 de sellette.According to a variant, in the case of loading of a semi-trailer 2, the underside 36 of the part front of the chassis is taken up by the central surface support represented by the support plate and retaining 25 of the transverse support structure 22 of the tilting support 17 to relieve or retract the stands 37 and 38 of semi-trailer 2 and protect and if necessary retain the pivot 30 of the fifth wheel.

A titre complémentaire, on précise ce qui suit.In addition, we specify what follows.

Une fois que la semi-remorque 2 ou le deuxième tracteur 4 est chargé, on relève les bras 18 et 19 du support basculant 17 et on verrouille l'ensemble du dispositif en position de transport et ceci lorsque la structure ferroviaire porteuse 10 est encore en position oblique de chargement.Once semi-trailer 2 or second tractor 4 is loaded, the arms 18 are raised and 19 of the tilting support 17 and it is locked the entire device in the transport position and this when the supporting railway structure 10 is still in oblique loading position.

L'actionnement du support basculant 17 est assuré préférentiellement par des moyens moteurs faisant partie de l'infrastructure c'est-à-dire des installations à quai.The actuation of the tilting support 17 is preferably provided by motor means part of the infrastructure that is to say dockside facilities.

On s'adapte facilement aux différentes hauteurs des sous-faces avant 36 des différents modèles de semi-remorques 2 existantes.We easily adapt to different heights of the front sub-faces 36 of the different existing semi-trailer models 2.

Pendant le transport, l'essentiel du soutien des efforts verticaux vient des béquilles 37 et 38 alors que la structure transversale d'appui 22 ne joue qu'un rôle secondaire d'appui.During transport, most of the support vertical forces comes from crutches 37 and 38 while the transverse support structure 22 does not play only a supporting secondary role.

Une seule unité ferroviaire 1 assure le transport de deux types de charges routières.A single rail unit 1 ensures the transport of two types of road loads.

On n'est pas obligé de disposer de wagons de format plus long pour le transport des tracteurs ce qui limiterait l'exploitation du système à des voies compatibles.We don't have to have longer format for transporting tractors this which would limit the operation of the system to lanes compatible.

On sécurise la charge routière dès son chargement en position oblique de la structure d'appui en la verrouillant en position.We secure the road load as soon as oblique loading of the support structure by locking it in position.

L'invention se rapporte aussi à un procédé de chargement et de déchargement d'une charge ou de plusieurs charges routières dans une unité routière du type défini au début de la description.The invention also relates to a method of loading and unloading of a load or several road loads in a road unit in type defined at the beginning of the description.

L'unité de transport ferroviaire 1 est dissociée par libération des moyens d'assemblage et pivotement de la structure ferroviaire porteuse 10 jusqu'à contact d'une de ses extrémités 11 ou 12 avec le sol du quai ou une rampe ou base d'accès 15 posée ou fixée sur le quai.Rail transport unit 1 is dissociated by release of the assembly means and pivoting of the supporting railway structure 10 until contact of one of its ends 11 or 12 with the platform floor or a ramp or access base 15 laid or fixed on the platform.

La structure transversale d'appui 22 du support basculant 17 est amenée au sol du quai ou en contact avec les structures de la rampe ou base d'accès 15.The transverse support structure 22 of the tilting support 17 is brought to the platform floor or contact with the structures of the ramp or base access 15.

Une semi-remorque 2 est tirée ou poussée par un tracteur 3 ou 4 en marche avant ou en marche arrière vers la structure ferroviaire porteuse 10 dans laquelle elle entre par une extrémité d'accès 11 ou 12 en passant au-dessus de la structure transversale d'appui 22 posée au sol ou sur la rampe ou base d'accès 15.A semi-trailer 2 is pulled or pushed by a tractor 3 or 4 in forward or in motion back towards the supporting railway structure 10 in which it enters via an access end 11 or 12 passing over the transverse structure support 22 placed on the ground or on the ramp or base access 15.

Lorsque la semi-remorque 2 est totalement engagée, le train arrière 35 du tracteur 3 ou 4 est sur le point de franchir par ses roues arrière 33 et 34 la structure transversale d'appui 22. Le conducteur poursuit le mouvement et dès qu'il perçoit la secousse caractéristique du franchissement par les roues arrière du premier élément transversal 23 de la structure transversale d'appui 22, il se prépare à arrêter le tracteur juste après ce franchissement, c'est-à-dire au moment où les roues arrière seront situées juste entre les deux éléments transversaux 23 et 24 de la structure transversale d'appui 22.When semi-trailer 2 is completely engaged, the rear axle 35 of the tractor 3 or 4 is about to cross by its rear wheels 33 and 34 the transverse support structure 22. The conductor continues the movement and as soon as he perceives the shaking characteristic of wheel crossing rear of the first transverse element 23 of the transverse support structure 22, it prepares for stop the tractor immediately after this crossing, that is to say when the rear wheels are located just between the two transverse elements 23 and 24 of the transverse support structure 22.

S'agissant du repère en position, il sait qu'alors la semi-remorque se trouvera dans la bonne position pour les opérations ultérieures de chargement et pour son transport.Regarding the benchmark in position, he knows then the semi-trailer will be in the correct position for subsequent loading operations and for its transport.

Les béquilles 37 et 38 de la semi-remorque 2 sont abaissées ou on utilise le rehaussement 39 de plancher, on dégonfle les suspensions du tracteur et la semi-remorque peut être désaccouplée de son tracteur pour reposer sur ses roues et ses béquilles ou sur ses roues et sur le rehaussement 39 de plancher.Crutches 37 and 38 of semi-trailer 2 are lowered or use the enhancement 39 of floor, deflate the tractor suspensions and the semi-trailer can be uncoupled from its tractor to rest on wheels and crutches or on its wheels and on the raising 39 of floor.

Le support basculant 17 est alors actionné en basculement vers le haut. Suite à son utilisation comme repère en position, la structure transversale d'appui 22 vient se plaquer contre la sous-face avant de la semi-remorque dans une position telle que la cavité de réception et de retenue 28 se trouve placée autour du pivot 30 de sellette.The tilting support 17 is then actuated by tilt up. Following its use as a reference in position, the transverse structure support 22 is pressed against the front underside of the semi-trailer in a position such that the receiving and retaining cavity 28 is placed around the pivot 30 of fifth wheel.

Cette structure transversale d'appui 22 est maintenue en appui contre la sous-face 36 en regard de la semi-remorque et ceci plus ou moins fortement selon l'actionnement des bras pivotants 18 et 19 du support basculant 17. Un simple soutien de calage est envisagé car il correspond à certaines conditions de chargement dans lesquelles les béquilles supportent pour la totalité ou l'essentiel les efforts verticaux. On peut lui préférer, dans certains cas, un soutien actif selon lequel l'avant de la semi-remorque est porté partiellement ou totalement par le support basculant 17 et ceci pour permettre de soulager les béquilles 37 et 38 et d'améliorer la stabilité du chargement en profitant en plus d'un effet de calage.This transverse support structure 22 is kept pressed against the underside 36 facing the semi-trailer and this more or less strongly depending on actuation of the pivoting arms 18 and 19 of the support tilting 17. A simple wedging support is envisaged because it corresponds to certain loading conditions in which the crutches support for the all or most of the vertical forces. We can prefer active support in some cases that the front of the semi-trailer is carried partially or totally by the tilting support 17 and this to relieve the crutches 37 and 38 and to improve the stability of the load in taking advantage in addition of a wedging effect.

La structure transversale d'appui 22 est immobilisée dans cette position par verrouillage et selon le cas les béquilles 37 et 38 restent en position de soutien ou sont rétractées ou escamotées.The transverse support structure 22 is immobilized in this position by locking and depending on the case the crutches 37 and 38 remain in support position or are retracted or retracted.

Après un éventuel arrimage par d'autres moyens, les opérations de chargement sont terminées. La structure ferroviaire porteuse 10 est pivotée pour sa remise en ligne dans sa position de transport. Après assemblage d'association de cette structure ferroviaire porteuse avec le ou les ensemble(s) d'extrémité 5 ou 6, l'unité ferroviaire de transport 1 est prête au départ.After possible stowage by others means, the loading operations are completed. The supporting railway structure 10 is pivoted to putting it back online in its transport position. After association assembly of this structure carrier railway with the set (s) 5 or 6, the rail transport unit 1 is ready to go.

Le déchargement s'effectue dans le sens inverse.Unloading takes place in the direction reverse.

Le chargement des tracteurs 3 et 4 se déroule d'une façon un peu différente.The loading of tractors 3 and 4 takes place in a slightly different way.

Après dissociation en oblique et pose de l'extrémité d'entrée 11 ou 12 de la structure ferroviaire porteuse 10 au sol du quai ou sur une rampe ou une base d'accès 15, le premier tracteur 3 entre, roule sur le fond de la structure ferroviaire porteuse 10 jusqu'en position maximale d'extrémité. Après immobilisation et arrimage du premier tracteur 3, le deuxième tracteur 4 entre en marche avant dans la structure ferroviaire porteuse.After dissociation in oblique and pose of entry end 11 or 12 of the structure load-bearing rail 10 on the platform floor or on a ramp or access base 15, the first tractor 3 between, rolls on the bottom of the railway structure carrier 10 to the maximum end position. After immobilization and stowage of the first tractor 3, the second tractor 4 goes forward in the supporting railway structure.

Lorsque le conducteur perçoit le franchissement du premier élément 23 de la structure transversale d'appui 22 qui se trouve comme précédemment sur le sol du quai ou sur une base ou rampe d'accès 15, il immobilise le tracteur juste après dans une position dans laquelle les roues arrière 33 et 34 se trouvent entre les éléments transversaux 23 et 24 de la structure transversale d'appui 22. Il sort du tracteur en bloquant éventuellement les freins.When the driver perceives the crossing of the first element 23 of the structure transverse support 22 which is located as previously on the platform floor or on a base or access ramp 15, it immobilizes the tractor just after in a position in which the wheels rear 33 and 34 are between the elements 23 and 24 of the transverse structure support 22. He leaves the tractor by blocking possibly the brakes.

On actionne le support basculant 17 en montée. Au cours de ce mouvement les roues arrière 33 et 34 se trouvent calées par la montée des éléments transversaux 23 et 24 puis levées jusqu'à une hauteur suffisante pour ne pas interférer avec les structures supérieures de l'ensemble d'extrémité correspondant 5 ou 6. On verrouille le support basculant 17 en position.The tilting support 17 is activated by climb. During this movement the rear wheels 33 and 34 are wedged by the rise of the elements transverse 23 and 24 then lifted to a height sufficient not to interfere with structures of the corresponding end assembly 5 or 6. The tilting support 17 is locked in position.

Le deuxième tracteur 4 se trouve immobilisé par calage de ses roues arrière 33 et 34 par les éléments transversaux 23 et 24 de la structure transversale d'appui 22.The second tractor 4 is immobilized by wedging its rear wheels 33 and 34 by the transverse elements 23 and 24 of the structure transverse support 22.

En raison du poids représenté par le tracteur 4, cette immobilisation s'avère déjà importante. Il est possible que pour des raisons de sécurité, un arrimage ou un autre verrouillage soit demandé.Due to the weight of the tractor 4, this immobilization is already important. he it is possible that for security reasons a lashing or other locking is requested.

On referme l'unité ferroviaire en pivotant la structure ferroviaire porteuse 10 et en assemblant la ou les extrémités dissociées 11 ou 12 à l'ensemble ou aux ensembles d'extrémité 5 ou 6. L'unité de transport ferroviaire 1 est alors prête au départ.We close the rail unit by pivoting the supporting rail structure 10 and assembling the or the dissociated ends 11 or 12 to the whole or to end assemblies 5 or 6. The transport unit Rail 1 is then ready for departure.

Le déchargement s'effectuant dans le sens inverse ne nécessite pas de description particulière.Unloading takes place in the direction reverse does not require a particular description.
