Description

VEHICULE DE MANUTENTION, NOTAMMENT PORTUAIRE.HANDLING VEHICLE, IN PARTICULAR PORT.
La présente invention concerne un véhicule de manutention, notamment portuaire, comportant une structure conçue apte à recevoir au niveau d' une surface de réception et à transporter une charge utile telle qu'un conteneur ou similaire, des moyens de roulement au sol conçus aptes à être entrainés par des moyens d' entrainement, des premiers moyens d'attelage conçus aptes à la traction d' une ou plusieurs remorques de transport de charges.The present invention relates to a handling vehicle, including a port, having a designed structure adapted to receive at a receiving surface and to transport a payload such as a container or the like, ground bearing means designed to be driven by drive means, first coupling means designed to pull one or more load transport trailers.
L'invention concerne encore un train formé d'au moins deux tels véhicules .The invention further relates to a train formed of at least two such vehicles.
La présente invention entre dans le domaine des véhicules à déplacement terrestre.The present invention is in the field of land-moving vehicles.
Dans les installations portuaires, il est connu d'effectuer le transport des marchandises en transit, en particulier quand ces marchandises sont des conteneurs , par des trains de remorques ou semi-remorques attelées à un véhicule tracteur.In port facilities, it is known to transport goods in transit, particularly when these goods are containers, by trains of trailers or semi-trailers coupled to a towing vehicle.
Cette conception de la manutention portuaire date d'une époque où les temps d'attente au chargement ou au déchargement, soit depuis des grues de quai effectuant la manutention entre un navire et un quai, soit depuis des moyens de manutention tels que des portiques de reprise au sol, étaient relativement longs, et permettaient d'envisager l'utilisation d'un véhicule tracteur pour d'autres missions, après dételage d'un train de remorques ou semi-remorques en attente.This concept of port handling dates back to a time when waiting times loading or unloading, either from dock cranes handling between a ship and a dock, or from handling devices such as gantry cranes. ground recovery, were relatively long, and allowed to consider the use of a towing vehicle for other missions, after unhitching a train of trailers or semi-trailers on hold.
Dans la pratique, on constate que les flux sont de plus en plus tendus, et qu'un véhicule tracteur reste attelé à vie aux remorques . L'utilisation d'un véhicule tracteur classique présente un certain nombre d'inconvénients connus. La nécessité d'une adhérence au sol convenable en toutes circonstances implique l'emport d'une charge de ballast conséquente, ce qui a une influence directe sur la consommation d'énergie du véhicule tracteur. De plus, ce dernier est souvent surdimensionné, de façon à faire face à la configuration la plus défavorable en ce qui concerne la masse de la charge tractée , ce qui fait que toute augmentation de la consommation d'énergie est démultipliée par le surdimensionnement de l'engin. Le surdimensionnement des moyens d'entrainement du véhicule tracteur entraine logiquement celui du véhicule lui-même.In practice, it can be seen that the flows are becoming more and more tense, and that a towing vehicle remains tied to trailers for life. The use of a conventional tractor vehicle has a number of known drawbacks. The need for a suitable ground adhesion in all circumstances implies the carrying of a substantial ballast load, which has a direct influence on the energy consumption of the towing vehicle. In addition, the latter is often oversized, so as to face the most unfavorable configuration with respect to the mass of the towed load, so that any increase in energy consumption is multiplied by the oversizing of the gear. Oversize the drive means of the towing vehicle logically drives that of the vehicle itself.
De ce fait, la consommation d'énergie, qui représente le premier facteur de coût en manutention portuaire, n'est pas maîtrisée avec les moyens connus, toujours surdimensionnés, et on constate peu de différence de consommation entre les trajets en charge et les trajets à vide. Il s'agit de la principale préoccupation des exploitants, qui se conjugue avec une préoccupation écologique plus universelle .As a result, the energy consumption, which represents the first cost factor in port handling, is not controlled with the known means, always oversized, and there is little difference in consumption between load paths and trips. empty. This is the main concern of the operators, which is combined with a more universal ecological concern.
Les coûts de main d' œuvre, qui représentent le second facteur de coût par ordre d'importance, restent élevés dans les solutions classiques, compte tenu des précautions que doivent prendre les opérateurs lors des positionnements relatifs et des accostages. L'ergonomie, aussi bien pour les pilotes d'engins de manutention, de dépose, ou d'emport des charges au niveau des trains de remorques, que pour les pilotes des véhicules tracteurs, est médiocre. Tout d'abord leur sécurité individuelle et celle des marchandises transportées sont mal assurées, ainsi que celle des véhicules. La longueur des trains de remorques tirés par tracteurs rend malcommode l'évolution sur des sites toujours très encombrés. L'accès des opérateurs aux postes de conduite des véhicules, souvent en hauteur, est malaisé voire pénible . Le centre de gravité relativement haut des véhicules tracteurs connus est lui aussi préjudiciable à la sécurité des biens et des personnes .Labor costs, which represent the second most important cost factor, remain high in conventional solutions, given the precautions operators must take in relative positioning and docking. Ergonomics, both for pilots of handling equipment, removal, or carriage of loads on the level of trailer trains, as for drivers of tractor vehicles, is mediocre. First of all their personal safety and that of the goods transported are poorly insured, as well as that of the vehicles. The length of trailer trains pulled by tractors makes it inconvenient to evolve on sites still very congested. Operator access to vehicle control stations, often at a height, is difficult or even painful. The relatively high center of gravity Known tractors are also detrimental to the safety of people and property.
Les temps d'attente des tracteurs et des remorques représentent l'essentiel de leur cycle de vie. Les exploitants veulent limiter l'investissement au strict nécessaire, et attendent une à cet effet une véritable polyvalence de leur matériel de manutention. L'immobilisation des véhicules de manutention pour reconditionnement et maintenance doit, de plus, être la plus réduite possible.The waiting times for tractors and trailers represent the bulk of their life cycle. Operators want to limit the investment to the bare necessities, and expect one to this effect a true versatility of their material handling. The immobilisation of the handling vehicles for repackaging and maintenance must, moreover, be as small as possible.
Enfin, un important problème consiste dans le coût de l'immobilisation de la surface de quai au pied du navire, donc du navire au quai, dont le loyer horaire est très élevé.Finally, a major problem is the cost of immobilizing the quay surface at the foot of the vessel, hence from the ship to the wharf, whose hourly rent is very high.
Dans le cas d'un navire porte-conteneurs usuel, il s'agit de décharger 14000 conteneurs en 8 heures. Les moyens au sol doivent donc être adaptés pour assurer cette cadence. La charge est conséquente, un conteneur de 20 pieds pouvant atteindre 35tonnes. Les allées des ports sont étroites, et la circulation de travée en travée exige une bonne maniabilité des trains de remorques utilisés . Les surfaces de circulation sont en principe en dévers pour l'écoulement d'eau, et l'adhérence doit être assurée en toutes conditions . Lors de la dépose , une surcharge dynamique intervient du fait du poids et de l'inertie du palonnier lui-même, au moment où le conducteur du spreader détend complètement les câbles pour effectuer la dépose sur un véhicule .In the case of a typical container ship, it means unloading 14000 containers in 8 hours. The ground means must therefore be adapted to ensure this pace. The load is consistent, a container of 20 feet up to 35 tons. The aisles of the ports are narrow, and the bay span traffic requires good maneuverability of the used trailer trains. The circulation surfaces are in principle in cant for the flow of water, and the adhesion must be assured in all conditions. During removal, a dynamic overload occurs because of the weight and inertia of the rudder itself, when the driver of the spreader completely relaxes the cables to perform the removal on a vehicle.
L'invention se propose de pallier ces problèmes de l'état de la technique, en particulier au niveau de la consommation d'énergie, en proposant un véhicule conçu apte à recevoir une charge similaire à celle d'une remorque, et, dans une version équipée de moyens d'entraînement, à tracter une ou plusieurs remorques . A cet effet, l'invention concerne un véhicule de manutention, notamment portuaire , comportant une structure conçue apte à recevoir au niveau d'une surface de réception et à transporter une charge utile telle qu'un conteneur ou similaire, des moyens de roulement au sol conçus aptes à être entrainés par des moyens d'entrainement, des premiers moyens d'attelage conçus aptes à la traction d'une ou plusieurs remorques de transport de charges , caractérisé par le fait que les organes les plus éloignés de l'appui au sol dudit véhicule sont des moyens de guidage ou/et d'arrêt de ladite charge utile que comporte ledit véhicule, et qui surmontent ladite surface de réception de ladite charge utile disposée en partie supérieure dudit véhicule .The invention proposes to overcome these problems of the state of the art, in particular in terms of energy consumption, by proposing a vehicle designed to receive a load similar to that of a trailer, and, in a version equipped with drive means, to tow one or more trailers. To this end, the invention relates to a handling vehicle, including a port, comprising a designed structure adapted to receive at a receiving surface and to transport a payload such as a container or the like, rolling means to designed to be driven by driving means, first coupling means designed to be able to pull one or more load-carrying trailers, characterized in that the bodies furthest from the support of the ground of said vehicle are means for guiding and / or stopping said payload that includes said vehicle, and which surmount said receiving surface of said payload disposed in the upper portion of said vehicle.
Selon une caractéristique de l'invention, les seuls organes dudit véhicule situés au-delà de ladite surface de réception, par rapport audit appui au sol , sont lesdits moyens de guidage ou/et d'arrêt.According to a characteristic of the invention, the only members of said vehicle located beyond said receiving surface, with respect to said ground support, are said guide means and / or stop.
Selon une autre caractéristique de l'invention, ledit véhicule comporte des premiers moyens de réception conçus aptes à recevoir une cabine amovible .According to another characteristic of the invention, said vehicle comprises first reception means designed to receive a removable cabin.
Selon une autre caractéristique de l'invention, ledit véhicule est conçu apte à être utilisé comme remorque et comporte à cet effet des seconds moyens d'attelage.According to another characteristic of the invention, said vehicle is designed to be used as a trailer and comprises for this purpose second coupling means.
Selon une autre caractéristique de l'invention, ledit véhicule est un porte-conteneurs.According to another characteristic of the invention, said vehicle is a container carrier.
L'invention concerne encore un train formé d'au moins deux tels véhicules .The invention further relates to a train formed of at least two such vehicles.
L'invention procure d'indéniables avantages à l'utilisateur. Tout d'abord, l'automoteur selon l'invention ne nécessite pas d'emport de ballast, dans la mesure où sa structure est conçue pour recevoir et transporter une charge utile, de la même façon que les remorques qu'il est conçu apte à tracter. La masse de sa structure constitue en elle-même un lest suffisant pour assurer l'adhérence en toute circonstance, à vide ou en charge. Les moyens d' entraînement peuvent donc être calculés au plus juste .The invention provides undeniable benefits to the user. First of all, the self-propelled device according to the invention does not require a ballast carriage, inasmuch as its structure is designed to receive and transport a payload, in the same way as the trailers that it is designed able to tow. The mass of its structure is in itself sufficient ballast to ensure adherence in any circumstance, empty or load. The drive means can therefore be calculated as accurately as possible.
De plus, la présence de l'automoteur dans un train de remorques fait gagner un véhicule sur l'effectif total de ce train. La puissance de traction est réduite en conséquence. Il n'est donc plus nécessaire de surdimensionner l'engin de traction.In addition, the presence of the self-propelled trailer in a trailer train saves a vehicle on the total strength of this train. The pulling power is reduced accordingly. It is therefore no longer necessary to oversize the traction unit.
La conjugaison de l'inutilité d'emport de ballast et du rôle utile du véhicule tracteur comme transporteur de charge permettent, ainsi, de dimensionner au plus juste les moyens d' entraînement du véhicule tracteur tout comme sa structure, et, donc, d'économiser de l'énergie pendant toutes les phases d'utilisation de ce véhicule, par rapport aux solutions connues .The combination of the futility of carrying ballast and the useful role of the towing vehicle as a load carrier thus make it possible to dimension the tractor vehicle's drive means as well as its structure, and therefore save energy during all phases of use of this vehicle, compared to known solutions.
Le véhicule automoteur selon l'invention est moins long que la configuration équivalente de l'art antérieur, constituée d'un tracteur attelé à une remorque, pour le même emport de charge et la même traction. Cette caractéristique permet donc de réduire sensiblement l'encombrement du site d'évolution.The self-propelled vehicle according to the invention is shorter than the equivalent configuration of the prior art, consisting of a tractor coupled to a trailer, for the same load carrying and the same traction. This characteristic therefore makes it possible to substantially reduce the size of the site of evolution.
Le centre de gravité très bas de l'engin procure une grande stabilité, notamment en cas d'emport de charges hautes, et, donc , une sécurité accrue .The very low center of gravity of the machine provides great stability, especially when carrying high loads, and therefore increased safety.
L'accessibilité aux opérateurs et aux agents de maintenance est facilitée grâce à l'accessibilité depuis le sol à tous les organes du véhicule automoteur selon l'invention. La position de conduite surbaissée, dans une zone sécurisée par rapport aux charges emportées , représente un important progrès sur le plan de la sécurité . Le véhicule automoteur selon l'invention présente encore l'avantage, dans une version préférée de porte-conteneurs, d'être multi-formats .Accessibility to operators and maintenance agents is facilitated by accessibility from the ground to all the organs of the self-propelled vehicle according to the invention. The lowered driving position, in a secure area relative to the loads carried, represents an important safety advance. The self-propelled vehicle according to the invention still has the advantage, in a preferred version of container ship, of being multi-formats.
En comparaison avec la configuration équivalente de l'art antérieur constituée d'un tracteur attelé à une remorque, le véhicule automoteur selon l'invention présente l'avantage de comporter un nombre réduit de composants , ce qui diminue à la fois le coût d'investissement, et les coûts de maintenance.In comparison with the equivalent configuration of the prior art consisting of a tractor coupled to a trailer, the self-propelled vehicle according to the invention has the advantage of having a reduced number of components, which decreases both the cost of investment, and maintenance costs.
Des véhicules automoteurs tracteurs peuvent être transformés en remorques , et réciproquement .Tractor self-propelled vehicles can be converted into trailers, and vice versa.

Tel que visible dans les figures des dessins joints, la présente invention concerne le domaine des véhicules à déplacement terrestre et en particulier les trains de remorques, et a trait à un véhicule automoteur pour la traction d'un tel train.As shown in the figures of the accompanying drawings, the present invention relates to the field of land-moving vehicles and in particular trailer trains, and relates to a self-propelled vehicle for the traction of such a train.
L'invention concerne un véhicule 1 automoteur de manutention, notamment portuaire . Tel que visible sur la figure 1 , ce véhicule 1 comporte une structure 2 conçue apte à recevoir et transporter une charge utile 3 telle qu'un conteneur ou similaire. Le véhicule 1 comporte des moyens de roulement au sol 4. Ces derniers sont conçus aptes à être entrainés par des moyens d' entrainement 5. Le véhicule 1 comporte des premiers moyens d'attelage 6 conçus aptes à la traction d'une ou plusieurs remorques 7 de transport de charges , ou d' autres véhicules 1 du même type .The invention relates to a self-propelled vehicle handling 1, including port. As can be seen in FIG. 1, this vehicle 1 comprises a structure 2 designed capable of receiving and transporting a payload 3 such as a container or the like. The vehicle 1 comprises ground rolling means 4. These are designed capable of being driven by drive means 5. The vehicle 1 comprises first coupling means 6 designed to be able to pull one or more trailers. 7 transporting loads, or other vehicles 1 of the same type.
L'amélioration de la gestion de l'énergie, au niveau d'une installation portuaire ou similaire, nécessite une meilleure ergonomie des postes de travail, de façon à faciliter les opérations de dépose et d' enlèvement des charges utiles 3 en une seule manœuvre, sans tâtonnement de la part de l'opérateur, ce qui permet de maîtriser la durée des cycles , et donc la consommation globale d'énergie. Il est donc important de faciliter, en particulier, la dépose d'une charge utile 3 sur un véhicule 1 selon l'invention. A cet effet, ce dernier comporte une surface 11 de réception de la charge utile 3. La structure 2 du véhicule 1 est conçue de telle façon que les organes du véhicule 1 , qui sont les plus éloignés de son appui au sol, sont des moyens de guidage 12 ou/et d'arrêt 13 de la charge utile 3. Ces moyens de guidage 12 ou/et d'arrêt 13 surmontent la surface de réception 11, qui est disposée en partie supérieure du véhicule 1.The improvement of energy management, at a port facility or similar, requires a better ergonomics of the workstations, so as to facilitate the operations of removal and removal of payloads 3 in a single maneuver without fumbling on the part of the operator, which makes it possible to control the duration of the cycles, and therefore the overall consumption of energy. It is therefore important to facilitate, in particular, the removal of a payload 3 on a vehicle 1 according to the invention. For this purpose, the latter comprises a surface 11 for receiving the payload 3. The structure 2 of the vehicle 1 is designed such that the bodies of the vehicle 1, which are furthest away from its support on the ground, are guide means 12 and / or stop 13 of the payload 3. These means 12 and / or stop 13 surmount the receiving surface 11, which is disposed in the upper part of the vehicle 1.
Dans une version préférée , les seuls organes du véhicule 1 situés au-delà de la surface de réception 11, par rapport à son appui au sol, sont ces moyens de guidage 12 ou/et d'arrêt 13, ce qui signifie que tout le reste du véhicule est sous la surface de réception 11, laquelle est préférentiellement plane.In a preferred version, the only members of the vehicle 1 located beyond the receiving surface 11, with respect to its support on the ground, are these guide means 12 and / or stop 13, which means that the whole the remainder of the vehicle is under the receiving surface 11, which is preferably flat.
Le véhicule dans sa version porte-conteneurs comporte des moyens de guidage 12 des conteneurs, qui s'élèvent au-dessus de la surface 11 de réception de la charge 3. Dans une réalisation préférée, leur hauteur au-dessus de cette surface est de 0,30 m, et ces moyens de guidage 12 sont avantageusement revêtus de moyens de protection conçus également dans une optique d'amortissement du bruit, tels des plaques de caoutchouc, d'élastomère, de bois ou de matières plastiques, ou similaire.The vehicle in its container-carrying version comprises means 12 for guiding the containers, which rise above the surface 11 for receiving the load 3. In a preferred embodiment, their height above this surface is 0.30 m, and these guide means 12 are advantageously coated protection means also designed in a noise damping optics, such as rubber, elastomer, wood or plastic, or the like.
Le véhicule 1 est, tel que visible sur la figure 3, avantageusement équipé d'un ensemble de moyens d'arrêt 13 pour le maintien de la charge en position, pour éviter tout accident lié à son éventuel glissement. Ces moyens d'arrêt 13 sont préférentiellement constitués de butées , fixes ou/et escamotables .The vehicle 1 is, as shown in Figure 3, advantageously equipped with a set of stop means 13 for holding the load in position, to avoid any accident related to its possible sliding. These stop means 13 are preferably made of abutments, fixed or / and retractable.
L'aménagement d'une surface 11 plane pour la réception de la charge 3 en partie supérieure du véhicule 1 permet, encore, une meilleure accessibilité à la charge 3 pour des engins tels que chariots élévateurs ou autres engins similaires se positionnant latéralement à la charge 3 pour sa manutention, et en autorisant notamment l'enfilage de fourches sous la charge 3. Pour améliorer l'économie d'énergie, le véhicule 1 selon l'invention est conçu dans une optique de réduction de masse, à pouvoir d'emport égal, par rapport à des véhicules usuels qui ont une masse de 12 à 14 tonnes pour l'emport d'un conteneur de 45 pieds, et pour ce faire sa structure 2 est calculée avec des profilés particuliers dans le but de son allégement, à résistance égale en charge et en fatigue. A titre d'exemple, la réduction de masse pour un véhicule conçu pour l'emport d'un conteneur de 45 pieds est au minimum de 3 tonnes.The arrangement of a plane surface 11 for the reception of the load 3 in the upper part of the vehicle 1 allows, again, a better accessibility to the load 3 for machines such as forklift trucks or other similar machines positioned laterally to the load 3 for its handling, and in particular allowing the threading of forks under load 3. To improve the energy saving, the vehicle 1 according to the invention is designed in a weight reduction optics, equal power of pay, compared to conventional vehicles that have a mass of 12 to 14 tonnes for the first time. It carries a 45-foot container, and to do this its structure 2 is calculated with special profiles for the purpose of its lightening, with equal resistance in load and fatigue. For example, the weight reduction for a vehicle designed to carry a 45-foot container is at least 3 tons.
Selon un mode de réalisation préféré, la masse du véhicule 1 est inférieure à 7 tonnes .According to a preferred embodiment, the mass of the vehicle 1 is less than 7 tons.
Dans ce même exemple, le gain énergétique, sur un attelage composé d'un véhicule automoteur 1 selon l'invention et d'une remorque 7 de même structure 2, en comparaison à une composition équivalente de l'art antérieur formée d'un tracteur et de deux remorques, est au moins de 10%, pour le seul effet du gain de 6 tonnes sur la masse de l'ensemble de l'attelage, toutes choses égales par ailleurs .In the same example, the energy gain, on a hitch consisting of a self-propelled vehicle 1 according to the invention and a trailer 7 of the same structure 2, in comparison with an equivalent composition of the prior art formed of a tractor and two trailers, is at least 10%, for the sole effect of the gain of 6 tons on the mass of the entire carriage, all things being equal.
Le rendement énergétique est donc encore amplifié du fait de cet allégement des structures 2. Dans l'hypothèse d'utilisation d'un train complet de remorques selon la même conception, ce gain de masse est démultiplié, ce qui réduit en proportion, non seulement la consommation, mais aussi la classe des moyens d' entraînement 5 qui peuvent être plus faiblement dimensionnés , et donc présenter une consommation horaire plus faible .The energy efficiency is therefore further amplified because of this lightening of structures 2. Assuming the use of a complete train of trailers according to the same design, this weight gain is multiplied, which proportionally reduces, not only consumption, but also the class of drive means 5 which can be more dimly sized, and therefore have a lower hourly consumption.
Le véhicule 1 selon l'invention est, de façon préférée, un véhicule qui est conçu pour être utilisé comme véhicule tracteur, tel que visible sur la figure 1 ou 3 : il comporte alors des moyens d' entraînement 5 conçus aptes à la traction d'une ou plusieurs remorques 7 ou d'un ou plusieurs véhicules 1 selon l'invention. Ce véhicule 1 est conçu pour être utilisé aussi comme remorque 7, dépourvu de moyens d' entraînement, tel que visible sur la figure 2. Il comporte, de préférence, à cet effet des seconds moyens d' attelage 18.The vehicle 1 according to the invention is, preferably, a vehicle which is designed to be used as a towing vehicle, as can be seen in FIG. 1 or 3: it then comprises driving means 5 designed to be able to pull one or more trailers 7 or one or more vehicles 1 according to the invention. This vehicle 1 is designed to be used also as a trailer 7, devoid of drive means, as visible in FIG. 2. It preferably comprises, for this purpose, second coupling means 18.
Il est ainsi possible de composer un train 30, tel que visible sur les figures 2 et 4 , comportant au moins un véhicule 1 tracteur, et au moins une remorque 7, préférentiellement construite avec une structure 2 et des moyens de roulement 4 identiques à ce tracteur. La standardisation des composants permet une importante économie de maintenance au niveau du parc de matériel roulant.It is thus possible to compose a train 30, as visible in FIGS. 2 and 4, comprising at least one tractor vehicle 1 and at least one trailer 7, preferably constructed with a structure 2 and rolling means 4 identical to that tractor. The standardization of components allows a significant maintenance savings in the fleet of rolling stock.
Dans tous les cas, la structure 2 du véhicule 1 comporte un châssis 14 autoportant, qui est spécialement conçu pour absorber la dépose de charges 3 lourdes , telles que notamment des containers, et résister à l'impact lié à la dépose souvent brusque sous des portiques de manutention ou des spreaders .In all cases, the structure 2 of the vehicle 1 comprises a self-supporting frame 14, which is specially designed to absorb the removal of heavy loads 3, such as in particular containers, and withstand the impact associated with the often abrupt removal under gantry cranes or spreaders.
Dans un mode de réalisation préféré, le véhicule 1 est un porte-conteneurs . Son châssis 14 est alors dimensionné, en version de base, pour la réception de conteneurs standard, de formats 20 pieds, 40 pieds, 45 pieds. Il comporte des moyens d'appui de ces conteneurs, au niveau d'une surface de réception 11, préférentiellement plane, et des moyens de guidage 12 pour la réception de tels conteneurs . Dans une version préférée et nullement limitative, chacun des véhicules peut recevoir, indifféremment, deux conteneurs de 20 pieds, ou un de 40 pieds, ou un de 45 pieds. Dans des versions plus lourdes, il est conçu apte à recevoir un multiple de ces quantités .In a preferred embodiment, the vehicle 1 is a container ship. Its chassis 14 is then sized, in basic version, for receiving standard containers, 20 feet, 40 feet, 45 feet. It comprises support means for these containers, at a reception surface 11, preferably flat, and guide means 12 for receiving such containers. In a preferred and non-limiting version, each of the vehicles can receive, indifferently, two containers of 20 feet, or a 40 feet, or a 45 feet. In heavier versions, it is designed to receive a multiple of these quantities.
Le véhicule 1 comporte préférentiellement une cabine 15 de conduite. Dans ce cas, celle-ci est avancée et de préférence surbaissée, sous le niveau de la surface de réception 11, et se trouve ainsi hors du champ d' évolution des conteneurs ou des charges 3 lors de leur dépose sur le véhicule 1 , ce qui est particulièrement sécurisant pour l'opérateur, dont l'accès au poste de conduite devient très facile et ergonomique .The vehicle 1 preferably comprises a driver's cab. In this case, it is advanced and preferably lowered, below the level of the receiving surface 11, and is thus outside the field of evolution of the containers or loads 3 when they are deposited on the vehicle 1, this who is particularly safe for the operator, whose access to the driving position becomes very easy and ergonomic.
Dans une version particulière, cette cabine 15 est constituée par un module amovible comportant des premiers moyens complémentaires 161 conçus aptes à coopérer avec des premiers moyens de réception 16 que comporte le châssis 14 du véhicule 1 pour son assemblage et son immobilisation sur ce dernier. Les moyens 16 peuvent en particulier être conçus sous forme de guidages aptes à recevoir des guidages complémentaires 161, la cabine 15 étant mobile à la façon d'un tiroir. Les moyens 16 peuvent être encore conçus sous forme de crochets ou de tourillons aptes à recevoir des moyens complémentaires 161, sous forme de crochets ou encore d' évidements . D'autres réalisations des moyens 16 et 161 peuvent être envisagées sans s'écarter de l'invention. Ce module cabine 15 est encore conçu apte à être raccordé à des organes moteurs constituant les moyens d' entraînement 5 , et à des moyens de commande que peut comporter le véhicule 1.In a particular version, this cabin 15 is constituted by a removable module comprising first complementary means 161 designed to cooperate with first receiving means 16 that includes the frame 14 of the vehicle 1 for its assembly and its immobilization on the latter. The means 16 may in particular be designed as guides capable of receiving complementary guides 161, the cabin 15 being movable in the manner of a drawer. The means 16 may be further designed in the form of hooks or pins adapted to receive complementary means 161 in the form of hooks or recesses. Other embodiments of the means 16 and 161 may be envisaged without departing from the invention. This cabin module 15 is still designed capable of being connected to the driving members constituting the drive means 5, and to control means that can comprise the vehicle 1.
Dans le cas avantageux d'un véhicule 1 à cabine 15 amovible, cette dernière peut ainsi être déposée avant une utilisation éventuelle du véhicule 1 comme remorque .In the advantageous case of a vehicle 1 with removable cab 15, the latter can be deposited before possible use of the vehicle 1 as a trailer.
L'attelage entre un premier véhicule 1 automoteur et une remorque 7, ou encore entre deux remorques 7 successives, est conçu pour autoriser un faible rayon de giration du train 30 ainsi formé .The coupling between a first self-propelled vehicle 1 and a trailer 7, or between two successive trailers 7, is designed to allow a small radius of gyration of the train 30 thus formed.
On notera, à ce propos, que la substitution d'un véhicule 1 automoteur selon l'invention à l'ensemble équivalent de l'art antérieur constitué par un tracteur et une remorque permet de réduire sensiblement le rayon de braquage du convoi, et en autorise un suivi monotrace. Cette substitution permet aussi la suppression d'au moins un essieu sur l'ensemble de l'attelage. Ceci se traduit par un allégement des coûts d'investissement, ainsi que de service , par économie de bandes de roulement ou de pneumatiques .It will be noted, in this regard, that the substitution of a self-propelled vehicle 1 according to the invention to the equivalent assembly of the prior art consisting of a tractor and a trailer makes it possible to substantially reduce the turning radius of the convoy, and allows one-way tracking. This substitution also allows the removal of at least one axle on the entire coupling. This translates into a reduction in investment costs, as well as service, for economy of treads or tires.
A cet effet, l'angle formé par deux véhicules successifs peut atteindre 120°. Tel que visible sur la figure 4, dans un mode de réalisation particulier, où chaque véhicule est conçu apte à la réception d'un conteneur de 45 pieds, le rayon de braquage intérieur RI de l'attelage constitué d'un automoteur et d'une remorque est de 12,4m, et le rayon extérieur RE hors tout, correspondant au rayon de giration, est inférieur ou égal à 18 m, pour des véhicules d'une longueur unitaire de 13,8m et d'une largeur de 2,5 m. Ceci procure une réduction d'environ 50% du rayon de giration du train 30 par rapport à l'art antérieur, et constitue un avantage important pour des évolutions sur des plate-formes très encombrées. Dans ce même exemple, l'attelage d'un automoteur 1 et d'une remorque 7 constitue une longueur de 31,9m. La longueur réduite par rapport à l'art antérieur offre ainsi une meilleure manoeuvrabilité , encore améliorée par la conception des véhicules avec une surface de réception de la charge basse, et ainsi un centre de gravité bas , à vide ou en charge . Cette manoeuvrabilité améliorée permet d' employer à ces tâches des personnels moins qualifiés , et de réserver les plus qualifiés à des opérations plus délicates. Cette conception assure encore une meilleure sécurité des personnes et des marchandises transportées .For this purpose, the angle formed by two successive vehicles can reach 120 °. As can be seen in FIG. 4, in a particular embodiment, in which each vehicle is designed capable of receiving a 45-foot container, the inside turning radius R1 of the hitch consisting of a self-propelled a trailer is 12.4m, and the outside radius RE overall, corresponding to the radius of gyration, is less than or equal to 18 m, for vehicles with a unit length of 13.8m and a width of 2, 5 m. This provides a reduction of about 50% of the gyration radius of the train 30 compared to the prior art, and is an important advantage for evolutions on very congested platforms. In this same example, the coupling of a self-propelled vehicle 1 and a trailer 7 constitutes a length of 31.9m. The reduced length compared to the prior art thus provides better maneuverability, further enhanced by the design of vehicles with a low load receiving surface, and thus a low center of gravity, empty or loaded. This improved maneuverability makes it possible to employ less qualified personnel in these tasks, and to reserve the most qualified for more delicate operations. This design ensures even better safety of people and goods transported.
La surface au sol est réduite par rapport à l'art antérieur, ce qui permet de positionner davantage d'attelages face à un navire, d'améliorer les opérations sous les grues ou portiques, et donc d'optimiser le chargement ou le déchargement d'un navire, et enfin de réduire la durée d'immobilisation du navire au quai, dont le loyer horaire est très élevé.The ground surface is reduced compared to the prior art, which makes it possible to position more hitches in front of a ship, to improve the operations under the cranes or gantries, and thus to optimize the loading or unloading of a ship, and finally to reduce the length of time the ship is idling at the wharf, for which the hourly rent is very high.
Pour atteindre d'aussi faibles rayons de braquage, chaque remorque 7 comporte préférentiellement deux essieux 19 pivotants constituant les moyens de roulement 4. Ces essieux 19 sont conçus aptes à pivoter en contre-rotation l'un de l'autre, sur un même véhicule, sous l'effet d'un palonnier 20 diagonal entre ces essieux, tel que visible sur la figure.To achieve such small turning radii, each trailer 7 preferably comprises two axles 19 pivoting constituting the rolling means 4. These axles 19 are designed to pivot counter-rotation to each other, on the same vehicle, under the effect of a spreader 20 diagonal between these axles, as visible on the face.
Tel que visible sur la figure 3, une version particulière du véhicule selon l'invention consiste en un véhicule 1 lourd, pour l'emport de plusieurs charges parallèlement l'une à l'autre, conçu au pas latéral standard des spreaders de dépose, et apte à recevoir d'un seul coup les deux ou quatre conteneurs que transporte ensemble un spreader, soit une charge de 160 tonnes environ dans le cas le plus défavorable pour quatre conteneurs de 20 pieds groupés en rectangle. Ce véhicule 1 peut tirer une remorque 7 de configuration analogue. On notera que le spreader est capable de faire une légère correction angulaire si l'alignement tracteur-remorque n'est pas parfait.As can be seen in FIG. 3, a particular version of the vehicle according to the invention consists of a heavy vehicle 1, for the carriage of several loads parallel to each other, designed at the standard lateral pitch of the spreaders of deposit, and able to receive in one fell swoop the two or four containers carried together by a spreader, ie a load of approximately 160 tonnes in the most unfavorable case for four containers of 20 feet grouped in a rectangle. This vehicle 1 can pull a trailer 7 of similar configuration. Note that the spreader is able to make a slight angular correction if the tractor-trailer alignment is not perfect.
Dans un mode de réalisation préféré , pour parfaire la sécurité des opérateurs, mais aussi pour réduire les zones d'attaque de corrosion, le véhicule 1 selon l'invention est réalisé avec des arrondis sur les zones saillantes , notamment par l'incorporation à la structure de tôles roulées ou/et de tubes rayonnes là où c'est possible.In a preferred embodiment, to improve the safety of the operators, but also to reduce the corrosion attack areas, the vehicle 1 according to the invention is made with rounding on the salient areas, in particular by incorporation into the structure of rolled sheets and / or rayon tubes where possible.
La résistance à l'impact du véhicule 1 selon l'invention provient, outre la conception du châssis 14, de l'utilisation d'au moins un essieu 19 muni de moyens de suspension et d'amortissement qui ont pour but d'améliorer l'absorption des chocs. Des barres anti-roulis permettent avantageusement d' absorber les chocs latéraux dûs aux accélérations et décélérations lors des opérations . Ces dispositions ont pour avantage supplémentaire d' allonger la durée de vie des véhicules concernés .The impact resistance of the vehicle 1 according to the invention comes, in addition to the design of the frame 14, the use of at least one axle 19 provided with suspension and damping means which are intended to improve the shock absorption. Anti-roll bars advantageously absorb lateral shocks due to accelerations and decelerations during operations. These provisions have the additional advantage of extending the life of the vehicles concerned.
De façon préférée, le véhicule 1 selon l'invention comporte un seul essieu 19 à chaque extrémité, de façon à éviter l'effet de ripage connu sur des remorques à deux essieux jumelés se traduisant par le cisaillement au niveau des bandes de roulement, et ainsi à augmenter la durée de vie des bandages ou pneumatiques , selon le cas , et réduire la consommation d'énergie de traction, la résistance étant moindre en phase de virage .Preferably, the vehicle 1 according to the invention comprises a single axle 19 at each end, so as to avoid the effect of known shifting on twin-axle trailers resulting in tread shear, thereby increasing tire or tire life, as the case may be, and reducing traction energy consumption, resistance being less in turn phase.
La position de ces essieux 19 par rapport au châssis 14, très proche de ses extrémités, définit un polygone de sustentation de surface importante, offre une bonne maniabilité d'un train de remorques , et accroît la performance de ce train . De façon préférée, l'empattement d'un véhicule conçu apte à recevoir un conteneur de 45 pieds est compris entre 10 et 11 mètres, préférentiellement voisin de 10,6 mètres, et la voie est comprise entre 2 et 3 mètres, préférentiellement voisine de 2,5 mètres. Au sein d'un train 30 formé de deux tels véhicules 1 attelés ensemble, l'écartement des essieux de part et d'autre de la zone d'attelage est compris entre 5 et 6 mètres, préférentiellement voisin de 5,2 mètres.The position of these axles 19 relative to the frame 14, very close to its ends, defines a large surface lift polygon, provides good handling of a train of trailers, and increases the performance of this train. Preferably, the wheelbase of a vehicle designed to receive a container 45 feet is between 10 and 11 meters, preferably close to 10.6 meters, and the track is between 2 and 3 meters, preferably close to 2.5 meters. In a train 30 formed of two such vehicles 1 coupled together, the spacing of the axles on either side of the coupling zone is between 5 and 6 meters, preferably close to 5.2 meters.
La conception particulière de la surface de réception 11 de la charge 3, des moyens de guidage 12 et d'arrêt 13 de celle-ci, permet aussi d'améliorer la productivité des opérateurs de grues de quai , portiques , ou similaires , qui ont moins à se concentrer pour la manœuvre de déchargement, notamment de conteneurs .The particular design of the receiving surface 11 of the load 3, the guide means 12 and the stop 13 thereof also makes it possible to improve the productivity of the operators of platform cranes, gantry cranes, or the like, which have less to concentrate on the unloading maneuver, especially containers.
Bien entendu, un véhicule 1 automoteur selon l'invention, conçu pour être tracteur, peut également être employé comme véhicule- frein en queue de train, pour des opérations de manutention particulières . Of course, a self-propelled vehicle 1 according to the invention, designed to be a tractor, can also be used as a brake vehicle at the end of the train, for particular handling operations.
