Abstract

The station of a disconnectable cableway with two or more carrying-hauling ropes (10, 12) comprises return pulleys (20, 22) arranged under the floor (34). After the uncoupling of the vehicles (24), the carrying-hauling ropes (10, 12) pass over downward deflection means (30, 32; 36, 38) which direct the ropes towards the return pulleys (20, 22). The vehicles disconnected from the ropes pass between the deflection pulleys towards the rear of the station. <IMAGE>

Description

L'invention est relative à une installation de transport à câbles aériens selon le préambule de la revendication 1.The invention relates to an overhead cable transport installation according to the preamble of claim 1.

Les téléphériques débrayables à deux ou plusieurs câbles porteurs-tracteurs à défilement continu ont dans chaque station de nombreuses poulies de guidage et de renvoi des câbles, relativement encombrantes. Les poulies de renvoi sont généralement disposées dans le prolongement et à la hauteur des voies, dans la partie supérieure de la station, à l'emplacement où s'étendent également les voies de transfert et de stockage sur lesquelles circulent les véhicules désaccouplés des câbles. Il peut être avantageux de renvoyer les câbles vers d'autres emplacements pour éviter toute interférence entre les câbles et les véhicules ou les passagers dans la station et faciliter le logement et/ou l'entraînement des poulies de renvoi.The detachable cable cars with two or more carrying cables with continuous running have in each station numerous pulleys for guiding and returning cables, relatively bulky. The return pulleys are generally arranged in line with and at the height of the tracks, in the upper part of the station, at the location where the transfer and storage tracks also run, on which the vehicles uncoupled from the cables run. It may be advantageous to return the cables to other locations to avoid any interference between the cables and the vehicles or passengers in the station and facilitate the accommodation and / or training of the return pulleys.

La présente invention a pour but de permettre la réalisation d'une station de structure simplifiée, dans laquelle les poulies de renvoi sont disposées sous le plancher portant les quais d'embarquement et de débarquement des passagers. et ce but est atteint par les caractéristiques de la revendication 1.The present invention aims to allow the realization of a simplified structure station, in which the return pulleys are arranged under the floor carrying the embarkation and disembarkation platforms for passengers. and this object is achieved by the features of claim 1.

Le document GB-A-910354 décrit un téléphérique à plusieurs câbles porteurs-tracteurs qui passent dans les stations sur des poulies de renvoi, disposées sous les quais. La benne est suspendue aux câbles par une suspente s'étendant à côté des câbles et portant des mors coincés en appui sur les câbles par le poids de la benne. A l'entrée de la station les câbles sont déviés vers le bas tandis que la benne roule sur une voie sensiblement horizontale en soulevant les mors des câbles pour désaccoupler la benne. La trajectoire de la benne diverge ensuite latéralement de celle des câbles cela étant possible grâce au décalage latéral de la suspente d'un côté des câbles.Document GB-A-910354 describes a cable car with several carrier-tractor cables which pass through the stations on return pulleys, arranged under the platforms. The grab is suspended from the cables by a hanger extending next to the cables and carrying jaws wedged in abutment on the cables by the weight of the grab. At the entrance of the station the cables are deflected downwards while the skip rolls on a substantially horizontal track by lifting the jaws of the cables to uncoupled the skip. The trajectory of the grab then diverges laterally from that of the cables, this being possible thanks to the lateral offset of the hanger on one side of the cables.

Les poulies de renvoi peuvent être des poulies motrices et/ou de tension et les mécanismes d'entraînement ou tendeurs sont également reportés dans la partie inférieure de la station, nettement séparée de la zone de circulation des passagers. Les poulies ou moyens de déviation sont disposés à l'entrée et à la sortie de la station pour dévier le câble vers le bas dès le désaccouplement des véhicules ou juste avant leur réaccouplement à la sortie de la station. Dans cette zone les portes des véhicules sont fermées et les voyageurs embarqués ne risquent pas de venir au contact des câbles ou des poulies de déviation, qui s'étendent de part et d'autre du véhicule. La longueur de la station n'est que faiblement ou pas augmentée et la place libérée par les câbles est disponible pour les voies de stockage et de transfert des véhicules.The return pulleys can be drive and / or tension pulleys and the drive mechanisms or tensioners are also fitted in the lower part of the station, clearly separated from the passenger circulation area. The pulleys or deflection means are arranged at the entrance and at the exit of the station to deflect the cable down as soon as the vehicles are uncoupled or just before their re-coupling at the exit of the station. In this area the doors of the vehicles are closed and the on-board travelers are not likely to come into contact with the cables or the deflection pulleys, which extend on either side of the vehicle. The length of the station is only slightly or not increased and the space freed up by the cables is available for the vehicle storage and transfer routes.

La déviation vers le bas des câbles implique un écartement des câbles correspondant au gabarit de passage des véhicules et si cet écartement est inférieur en ligne il suffit de dévier latéralement les câbles après la zone de désaccouplement et avant la zone de réaccouplement pour atteindre un écartement suffisant. Dans une installation à deux câbles porteurs-tracteurs, formant deux boucles sans fin, auxquels sont suspendus en ligne les véhicules, chaque câble passe à l'entrée et à la sortie de la station sur une poulie de déviation à axe transversal à la direction de défilement des câbles. Les câbles, qui sétendent avant les poulies de déviation dans un plan sensiblement horizontal, passent dans un plan vertical ou incliné ou plus exactement dans deux plans légèrement décalés, pour autoriser le croisement des câbles et les poulies de renvoi sont disposées dans ces plans verticaux ou inclinés.The downward deflection of the cables implies a cable spacing corresponding to the vehicle clearance gauge and if this spacing is less in line it is sufficient to laterally deflect the cables after the uncoupling zone and before the re-coupling zone to achieve sufficient spacing. . In an installation with two towing cables, forming two endless loops, to which the vehicles are suspended in line, each cable passes at the entrance and at the exit of the station on a deflection pulley with axis transverse to the direction of cable run. The cables, which extend before the deflection pulleys in a substantially horizontal plane, pass in a vertical or inclined plane or more exactly in two slightly offset planes, to allow the cables to cross and the deflection pulleys are arranged in these vertical planes or tilted.

Le système de guidage et de renvoi des câbles, selon l'invention, présente une symétrie par rapport au plan vertical qui contient l'axe longitudinal de la station.The cable guidance and return system according to the invention has symmetry with respect to the vertical plane which contains the longitudinal axis of the station.

Dans le cas où l'écartement des câbles avant leur déviation est plus grand que la largeur du véhicule, les deux poulies ou moyens de déviation peuvent être dans des plans verticaux espacés et être suivies de galets de guidage qui orientent les câbles vers les poulies de renvoi. L'une et de préférence celle des poulies de déviation disposée du côté intérieur des voies, ou les deux poulies de déviation peuvent être légèrement inclinées pour s'étendre chacune dans une face d'un dièdre à arête orientée dans la direction longitudinale des câbles et au-dessus de ceux-ci. Cette inclinaison oriente automatiquement le câble transversalement en direction de la poulie de renvoi et évite ou limite le nombre des galets de guidage additionnels. La disposition à la sortie de la station est bien entendu symétrique de celle à l'entrée.In the case where the spacing of the cables before their deflection is greater than the width of the vehicle, the two pulleys or deflection means may be in spaced vertical planes and be followed by guide rollers which orient the cables towards the pulleys of dismissal. One and preferably that of the deflection pulleys arranged on the inner side of the tracks, or the two deflection pulleys may be slightly inclined so as to each extend in one face of a dihedral with an edge oriented in the longitudinal direction of the cables and above these. This inclination automatically orients the cable transversely in the direction of the return pulley and avoids or limits the number of additional guide rollers. The layout at the station exit is of course symmetrical with that at the entrance.

Lorsque l'écartement des câbles avant leur déviation est de l'ordre de la largeur du véhicule ou légèrement inférieur à celle-ci, une disposition inclinée des poulies de déviation faisant diverger les câbles permet d'accroître l'écartement des poulies à la hauteur du véhicule pour dégager le gabarit de passage des véhicules. La poulie de déviation du câble s'étendant à l'extérieur de la voie est de préférence inclinée au minimum, afin de ne pas trop décaler la poulie de renvoi vers l'extérieur du côté éloigné de l'autre voie. La poulie de déviation intérieure est par contre inclinée suffisamment pour guider le câble sur la poulie de renvoi.When the spacing of the cables before their deflection is of the order of the width of the vehicle or slightly less than this, an inclined arrangement of the deflection pulleys causing the cables to diverge makes it possible to increase the spacing of the pulleys to the height of the vehicle to clear the vehicle clearance gauge. The cable deflection pulley extending outside the track is preferably inclined at least, so as not to shift the deflection pulley too far outwards on the far side of the other track. The internal deflection pulley is however inclined enough to guide the cable on the deflection pulley.

Toute la machinerie et/ou le système tendeur des câbles est localisé dans le bas de la station, ce qui limite les frais d'installation. Le diamètre des poulies de renvoi peut être inférieur à l'écartement entre le brin montant et le brin descendant du câble correspondant et la différence est alors compensée soit par l'inclinaison des poulies de déviation, soit par des galets de guidage supplémentaires.All the machinery and / or the cable tensioning system is located at the bottom of the station, which limits installation costs. The diameter of the deflection pulleys can be less than the distance between the rising strand and the descending strand of the corresponding cable and the difference is then compensated either by the inclination of the deflection pulleys, or by additional guide rollers.

Selon un développement de l'invention, l'écartement entre la voie montante et la voie descendante permet le logement d'une voie de garage centrale s'étendant sur toute la longueur de la station en passant entre les deux poulies de déviation internes.According to a development of the invention, the spacing between the upward track and the downward track allows the accommodation of a central garage track extending over the entire length of the station passing between the two internal deflection pulleys.

L'invention est applicable à une installation à deux câbles porteurs-tracteurs se déplaçant en synchronisme et dont l'écartement correspond sensiblement à la largeur des véhicules, mais cet écartement peut bien entendu être supérieur ou nettement inférieur et dans ce dernier cas il suffit d'accroître leur écartement après le désaccouplement des véhicules et avant leur déviation vers le bas ou à la sortie de la station de diminuer cet écartement entre les poulies de déviation et la zone d'accouplement. L'invention est également applicable à des installations ayant des câbles porteurs-tracteurs décalés en hauteur l'un par rapport à l'autre ou ayant plus de deux câbles porteurs-tracteurs.The invention is applicable to an installation with two carrying cables-tractors moving in synchronism and whose spacing corresponds substantially to the width of the vehicles, but this spacing can of course be greater or significantly less and in the latter case it suffices to '' increase their spacing after uncoupling the vehicles and before their deviation downwards or at the exit of the station to decrease this spacing between the deviation pulleys and the coupling zone. The invention is also applicable to installations having carrier-tractor cables offset in height relative to one another or having more than two carrier-tractor cables.

Selon un développement de l'invention, les moyens de déviation des câbles sont des trains de galets qui dévient les câbles vers le bas suivant une trajectoire inclinée amenant les câbles en-dessous des quais où sont disposées les poulies de renvoi qui s'étendent dans le plan incliné défini par la trajectoire inclinée des câbles. La longueur de la station n'est que faiblement augmentée car le tronçon incliné des câbles peut coïncider avec le tronçon d'accélération ou de décélération des véhicules.According to a development of the invention, the means for deflecting the cables are trains of rollers which deflect the cables downward along an inclined path bringing the cables below the platforms where the deflection pulleys which are arranged in the inclined plane defined by the inclined path of the cables. The length of the station is only slightly increased because the inclined section of the cables can coincide with the acceleration or deceleration section of the vehicles.

  • Figure 1 is a schematic perspective view of an installation according to the invention;

Sur les figures, deux câbles porteurs-tracteurs 10, 12 d'une installation de transport à câbles aériens, s'étendent entre deux stations dont seule une 14 est représentée. Chaque câble 10, 12 forme une boucle sans fin s'étendant le long d'une voie montante 16 et d'une voie descendante 18 et passant dans les stations sur une poulie de renvoi 20, 22, qui peut être une poulie motrice d'entraînement du câble 10, 12 et/ou une poulie de tension. Les deux câbles 10, 12 sont entraînés en continu en synchronisme et dans l'exemple illustré par les figures, ils sont parallèles à un même niveau horizontal. Des véhicules 24 sont accouplés aux deux câbles 10, 12 par un chariot 26 à pinces débrayables, plusieurs véhicules 24 pouvant se succéder ou être échelonnés le long des câbles 10, 12. A l'entrée d'une station 14 les véhicules 24 sont désaccouplés des deux câbles 10, 12 par ouverture des pinces d'accouplement, sont décélérés et pris en charge par des rails de transfert 28 passant devant des quais d'embarquement et de débarquement et conduisant les véhicules 24 vers la voie opposée. A la sortie les véhicules sont réaccélérés avant d'être réaccouplés aux deux câbles 10, 12. Une telle installation, bien connue des spécialistes, est par exemple décrite dans le brevet européen No. 93.680 auquel on se reportera pour de plus amples détails, notamment sur les avantages des deux câbles porteurs-tracteurs.In the figures, two carrier-towing cables 10, 12 of an overhead cable transport installation, extend between two stations of which only one 14 is shown. Each cable 10, 12 forms an endless loop extending along an upward path 16 and a downward path 18 and passing through the stations on a return pulley 20, 22, which can be a drive pulley of cable drive 10, 12 and / or a tension pulley. The two cables 10, 12 are driven continuously in synchronism and in the example illustrated by the figures, they are parallel at the same horizontal level. Vehicles 24 are coupled to the two cables 10, 12 by a carriage 26 with disengageable clamps, several vehicles 24 being able to follow one another or be staggered along the cables 10, 12. At the entrance to a station 14, the vehicles 24 are uncoupled two cables 10, 12 by opening the coupling clamps, are decelerated and supported by transfer rails 28 passing in front of embarkation and disembarkation docks and leading the vehicles 24 to the opposite lane. At the exit, the vehicles are re-accelerated before being re-coupled to the two cables 10, 12. Such an installation, well known to specialists, is for example described in European patent No. 93.680 to which reference will be made for further details, in particular on the advantages of the two carrier cables.

Sur les figures 2 à 4, un véhicule 24 vient d'entrer en station et son chariot 26 roule déjà sur le rail de transfert 28 pendant qu'une rampe (non représentée) de commande des pinces d'accouplement provoque leur ouverture et le désaccouplement du véhicule 24 des câbles 10, 12. Le véhicule 24 est décéléré par tout moyen approprié, par exemple par des roues à pneumatique de freinage et entraîné sur la voie de transfert, notamment par une chaîne d'entraînement, d'une manière bien connue, vers le quai de débarquement où les portes du véhicule s'ouvrent. A la sortie de la zone de désaccouplement du véhicule 24, les câbles 10, 12 passent chacun sur une poulie de déviation 30, 32, qui oriente vers le bas le câble en direction du plancher 34 de la station, qu'il traverse pour passer sur la poulie de renvoi correspondante 20, 22 avant de rejoindre la voie opposée où il passe à nouveau sur une poulie de déviation 36, 38, disposée avant la zone de réaccouplement du véhicule 24. Les poulies de renvoi 20, 22, sous le plancher 34, sont à axes horizontaux orientés dans la direction longitudinale de la station et les deux poulies de renvoi 20, 22 sont décalées latéralement l'une par rapport à l'autre et faiblement dans la direction longitudinale pour permettre le croisement des câbles 10, 12. Les axes des poulies de renvoi 20, 22 peuvent être alignés, mais les avantages du décalage latéral apparaîtront par la suite. Les poulies de renvoi 20, 22 peuvent être des poulies motrices et elles sont alors entraînées par des moteurs (non représentés). Elles peuvent être des poulies de tension et à cet effet être mobiles.In FIGS. 2 to 4, a vehicle 24 has just entered the station and its carriage 26 is already rolling on the transfer rail 28 while a ramp (not shown) for controlling the coupling clamps causes them to open and uncoupling vehicle 24 cables 10, 12. Vehicle 24 is decelerated by any suitable means, for example by pneumatic braking wheels and driven on the transfer path, in particular by a drive chain, in a well known manner , to the landing platform where the vehicle doors open. At the exit from the uncoupling zone of the vehicle 24, the cables 10, 12 each pass over a deflection pulley 30, 32, which directs the cable downwards towards the floor 34 of the station, which it crosses to pass on the corresponding return pulley 20, 22 before joining the opposite path where it again passes over a deflection pulley 36, 38, disposed before the re-coupling zone of the vehicle 24. The return pulleys 20, 22, under the floor 34, are with horizontal axes oriented in the longitudinal direction of the station and the two return pulleys 20, 22 are offset laterally with respect to each other and slightly in the longitudinal direction to allow the crossing of the cables 10, 12 The axes of the return pulleys 20, 22 can be aligned, but the advantages of the lateral offset will become apparent later. The return pulleys 20, 22 can be drive pulleys and they are then driven by motors (not shown). They can be tension pulleys and for this purpose be mobile.

La largeur du véhicule 24 représenté aux figures 2 à 4 est inférieure à l'écartement "d" des câbles 10, 12 dans la zone de déviation, qui se trouve après la zone de désaccouplement à l'entrée de la station, vu dans le sens de déplacement du véhicule et avant la zone de réaccouplement à la sortie de la station. Cet écartement "d" peut être le même en ligne, mais il peut également être imposé par des galets de guidage provoquant une déviation latérale des câbles 10, 12 après le désaccouplement du véhicule 24. La poulie de déviation 30, 38, disposée à l'extérieur de la voie descendante ou montante, est verticale avec un axe orienté transversalement à la voie pour dévier le câble de 90° et la position relative de cette poulie de déviation 30, 38 et de la poulie de renvoi 20, 22 associée est telle que le câble 10, 12 s'étend linéairement et verticalement entre les deux poulies. La poulie de déviation 32, 36, disposée à l'intérieur des voies, est inclinée latéralement pour dévier le câble 10, 12 latéralement et l'orienter vers la poulie de renvoi associée 20, 22. L'écartement entre les poulies de déviation 30, 32; 36, 38 au droit du passage du véhicule est supérieur à l'écartement "d" des câbles 10, 12 et il permet le passage du véhicule entre les deux poulies de déviation vers la partie arrière de la station (non représentée) où sont les quais d'embarquement et de débarquement et les zones de circulation des passagers. Les portes du véhicule 24 sont fermées lorsque celui-ci n'est pas dans cette partie arrière et une barrière sépare bien entendu cette partie arrière de la partie avant où défilent les câbles 10, 12 et sont disposées les poulies de déviation 30, 32; 36, 38. La position verticale des poulies de déviation extérieures 30, 38 évite toute augmentation de la largeur de la station et permet une disposition côte-à-côte des poulies de renvoi 20, 22 et de leur machinerie.The width of the vehicle 24 shown in FIGS. 2 to 4 is less than the spacing "d" of the cables 10, 12 in the deflection zone, which is located after the decoupling zone at the entrance to the station, seen in the direction of movement of the vehicle and before the re-coupling zone at the station exit. This spacing "d" can be the same in line, but it can also be imposed by guide rollers causing a lateral deflection of the cables 10, 12 after uncoupling of the vehicle 24. The deflection pulley 30, 38, disposed at the exterior of the downward or upward track, is vertical with an axis oriented transversely to the track for deviating the cable by 90 ° and the relative position of this deflection pulley 30, 38 and the associated deflection pulley 20, 22 is such that the cable 10, 12 extends linearly and vertically between the two pulleys. The deflection pulley 32, 36, disposed inside the tracks, is inclined laterally to deflect the cable 10, 12 laterally and orient it towards the associated deflection pulley 20, 22. The spacing between the deflection pulleys 30 , 32; 36, 38 in line with the passage of the vehicle is greater than the spacing "d" of the cables 10, 12 and it allows the passage of the vehicle between the two deflection pulleys towards the rear part of the station (not shown) where the embarkation and disembarkation docks and passenger traffic areas. The doors of the vehicle 24 are closed when the latter is not in this rear part and a barrier of course separates this rear part from the front part where the cables 10, 12 run and the deflection pulleys 30, 32 are arranged; 36, 38. The vertical position of the external deflection pulleys 30, 38 prevents any increase in the width of the station and allows a side-by-side arrangement of the deflection pulleys 20, 22 and their machinery.

En inclinant les poulies de déviation intérieures 32, 36 le diamètre des poulies de renvoi 20, 22 peut être inférieur à l'écartement des deux voies 16, 18 sans nécessiter de galets de guidage additionnels. Il est clair que les poulies de déviation intérieures 32, 36 peuvent également être verticales, le câble 10, 12 étant alors guidé vers les poulies de renvoi 20, 22 par des galets de guidage (non représentés). De même, lors d'un décalage latéral des poulies de renvoi 20, 22 par rapport aux poulies de déviation extérieures 30, 38 ce décalage peut être compensé par des galets de guidage. Le système de câbles est entièrement symétrique par rapport à l'axe longitudinal 40 de la station, et le câble extérieur de la voie montante devient le câble intérieur de la voie descendante et inversement.By tilting the internal deflection pulleys 32, 36 the diameter of the deflection pulleys 20, 22 can be less than the spacing of the two tracks 16, 18 without requiring additional guide rollers. It is clear that the internal deflection pulleys 32, 36 can also be vertical, the cable 10, 12 then being guided towards the return pulleys 20, 22 by guide rollers (not shown). Similarly, during a lateral offset of the deflection pulleys 20, 22 relative to the external deflection pulleys 30, 38 this offset can be compensated for by guide rollers. The cable system is completely symmetrical with respect to the longitudinal axis 40 of the station, and the outer cable of the uplink becomes the interior cable of the downlink and vice versa.

La déviation des câbles 10, 12 vers le bas sous le plancher 34 de la station libère la partie supérieure de la station et dans certaines installations, à écartement suffisant des voies montante 16 et descendante 18, il est possible de loger une voie de stockage centrale 42, représentée en trait discontinu sur la figure 4, qui s'étend sur toute la longueur de la station, en passant notamment entre les deux poulies de déviation intérieures 32, 36.The deflection of the cables 10, 12 down under the floor 34 of the station frees the upper part of the station and in certain installations, with sufficient spacing of the upward 16 and downward 18 tracks, it is possible to accommodate a central storage track 42, shown in broken lines in FIG. 4, which extends over the entire length of the station, passing in particular between the two internal deflection pulleys 32, 36.

La figure 5, analogue à la figure 4, illustre une variante de réalisation, dans laquelle les mêmes numéros de repère sont utilisés pour désigner des éléments équivalents. L'écartement "d" entre les deux câbles 10, 12 au niveau des poulies de déviation 30, 32; 36, 38 est sensiblement égal ou légèrement inférieur à la largeur du véhicule 24. Le gabarit de passage du véhicule 24 est augmenté en inclinant latéralement la poulie de déviation extérieure 30, 38, les deux poulies de déviation 30, 32; 36, 38 étant alors contenues dans les faces d'un dièdre à arête disposée dans la direction longitudinale des câbles 10, 12 et au-dessus de ceux-ci. Les poulies de renvoi 20, 22 sont décalées vers l'extérieur d'une valeur correspondante, mais il est possible de prévoir des galets de guidage, évitant ce décalage latéral. L'inclinaison des poulies de déviation extérieures 30, 38 est de préférence le plus faible possible.Figure 5, similar to Figure 4, illustrates an alternative embodiment, in which the same reference numbers are used to designate equivalent elements. The spacing "d" between the two cables 10, 12 at the level of the deflection pulleys 30, 32; 36, 38 is substantially equal to or slightly less than the width of the vehicle 24. The clearance gauge for the vehicle 24 is increased by laterally tilting the external deflection pulley 30, 38, the two deflection pulleys 30, 32; 36, 38 then being contained in the faces of a dihedral with an edge arranged in the longitudinal direction of the cables 10, 12 and above them. The return pulleys 20, 22 are offset towards the outside by a corresponding value, but it is possible to provide guide rollers, avoiding this lateral offset. The inclination of the external deflection pulleys 30, 38 is preferably as small as possible.

La variante de réalisation illustrée par les figures 6 et 7, sur lesquelles les mêmes numéros de repère sont utilisés, comporte des trains de galets de déviation 30, 32 qui orientent les câbles sur une trajectoire inclinée sous le plancher 34 de la station où sont disposées les poulies de renvoi 20, 22 à axes inclinés pour s'étendre dans le plan des câbles 10, 12. Lorsque le diamètre des poulies de renvoi est inférieure a l'écartement "d" des câbles en ligne des galets de guidage 44 provoquent une déviation latérale des câbles.The variant embodiment illustrated in FIGS. 6 and 7, in which the same reference numbers are used, comprises trains of deflection rollers 30, 32 which orient the cables on an inclined path under the floor 34 of the station where the stations are arranged. the return pulleys 20, 22 with inclined axes to extend in the plane of the cables 10, 12. When the diameter of the return pulleys is less than the spacing "d" of the cables in line with the guide rollers 44 cause a lateral deviation of cables.

L'invention a été décrite dans son application préférentielle à deux câbles porteurs-tracteurs et à véhicules suspendus à ces câbles en ligne. Elle est applicable à des installations du type décrit dans le brevet français No. 2.572.698 ayant un nombre supérieur de câbles, par exemple quatre, encadrant le véhicule ou tout autre nombre.The invention has been described in its preferred application to two carrier-tractor cables and to vehicles suspended from these cables in line. It is applicable to installations of the type described in French patent No. 2,572,698 having a higher number of cables, for example four, framing the vehicle or any other number.
