Abstract

An aerial transportation system including two generally parallel endless aerial carrier and traction cables is disclosed in which apparatus is respectively associated with each of the cables for separately supporting each cable. The supporting apparatus associated with each cable each comprise at least one basic balance beam, at least one roller rotatably mounted at one end of the balance beam for engaging its associated cable and at least one support balance beam with the basic balance beam being pivotally mounted at one end on the support balance beam for pivotal movement about a pivot axis extending at right angles to the cables. A support structure is provided for the balance beams with the support balance beam being pivotally mounted on the support structure. The basic balance beams, rollers and support balance beam associated with each cable are arranged on their respective support structures in facing relation to each other so that the basic balance beams on the respective support structures, and located in facing relation to each other, are mechanically independent of each other. The amplitude of pivoting of the basic balance beams about their respective pivot axis are limited between two predetermined extreme positions.

Description

L'invention concerne un dispositif de maintien de câbles et installation de transport à câbles aériens comportant un tel dispositif.The invention relates to a cable holding device and installation for overhead cable transport comprising such a device.

On connaît déjà (brevet européen 93 680) un dispositif de maintien de câbles destiné à une installation de transport à deux câbles aériens porteurs et tracteurs, comportant un pylône, une potence portée par le pylône et des balanciers garnis de galets sur lesquels roulent les câbles, portés par la potence. Plus précisément, ce dispositif connu comprend des balanciers élémentaires qui, pour chaque câble, comportent un fer plat sur lequel sont montés deux galets, les deux fers plats des deux câbles étant réunis rigidement entre eux grâce à un étrier rigide. Ce balancier élémentaire constitue un ensemble monobloc indéformable monté pivotant par ses fers plats autour d'un axe orthogonal aux câbles sur des poutrelles elles-mêmes montées pivotantes. La caractéristique constructive principale de ce dispositif connu est que d'une part l'écartement des galets correspondants aux deux câbles et maintenu positivement constant et égal à l'écartement des câbles et que, d'autre part, les mouvements de pivotement d'ensemble des galets (autour de l'axe de pivotement des fers plats) correspondant aux deux câbles sont effectués positivement en synchronisme parfait c'est-à-dire que l'on impose un pivotement symétrique des balanciers. Ce maintien positif de l'écartement et du synchonisme ainsi que de la symétrie du pivotement est obtenue grâce à l'étrier rigide solidarisant en un ensemble monobloc et indéformable les galets (ou pk.s précisément leurs axes de rotation) situés en correspondance et associés aux deux câbles. Compte tenu du passage devant être laissé libre entre les câbles pour le chariot ou similaire portant le véhicule, l'étrier a une forme générale de U renversé. Cette structure connue répond au soucis d'assurer une symétrie et un synchronisme parfait entre les deux câbles et donc des organes qui leurs sont associés. Si du point de vue théorique ce souci paraît légitime, il n'en est pas de même du point de vue pratique. En effet, malgré le soin apporté en vue de conférer aux câbles les mêmes paramètres physiques (notamment longueur, vitesse, tension, etc...) ces paramètres peuvent, en pratique, varier largement d'un câble à l'autre sur une même section transversale, ne serait-ce que du fait que les parcours des câbles sont distincts l'un de l'autre (les parcours étant globalement éventuellement accidentés) avec toutes les conséquences qui en résultent. Dans ces condition, le maintien du synchronisme ou de la symétrie de mouvement entre les balanciers ou les galets peut en fait se révéler être un inconvénient particulièrement gênant dans la mesure où il est générateur de contraintes supplémentaires dans le dispositif de maintien des câbles.Already known (European patent 93 680) a cable holding device intended for a transport installation with two overhead carrier cables and tractors, comprising a pylon, a bracket carried by the pylon and pendulums furnished with rollers on which the cables run , carried by the gallows. More specifically, this known device comprises elementary pendulums which, for each cable, comprise a flat iron on which two rollers are mounted, the two flat bars of the two cables being rigidly joined together thanks to a rigid bracket. This elementary balance constitutes a non-deformable monobloc assembly mounted to pivot by its flat bars around an axis orthogonal to the cables on beams themselves pivotally mounted. The main constructive characteristic of this known device is that on the one hand the spacing of the rollers corresponding to the two cables and kept positively constant and equal to the spacing of the cables and that, on the other hand, the overall pivoting movements rollers (around the pivoting axis of the flat bars) corresponding to the two cables are made positively in perfect synchronism, that is to say that a symmetrical pivoting of the pendulums is imposed. This positive maintenance of the spacing and of the synchonism as well as of the symmetry of the pivoting is obtained thanks to the rigid stirrup joining in a monobloc and undeformable assembly the rollers (or pk.s precisely their axes of rotation) located in correspondence and associated to the two cables. Given the passage to be left free between the cables for the carriage or the like carrying the vehicle, the stirrup has a general shape of an inverted U. This known structure responds to the concerns of ensuring perfect symmetry and synchronism between the two cables and therefore of the members associated with them. If from a theoretical point of view this concern seems legitimate, it is not the same from a practical point of view. In fact, despite the care taken to give cables the same physical parameters (in particular length, speed, tension, etc.), these parameters can, in practice, vary widely from one cable to another on the same cross section, if only because the cable paths are distinct from each other (the paths being generally possibly uneven) with all the consequences which result therefrom. Under these conditions, maintaining synchronism or symmetry of movement between the pendulums or the rollers can in fact prove to be a particularly annoying drawback insofar as it generates additional stresses in the cable holding device.

L'invention vise à remédier à ces inconvénients et à cet effet elle propose un dispositif de maintien des câbles d'une installation ayant un ou plusieurs véhicules supportés par au moins deux câbles porteurs et tracteurs parallèles, du type comportant, pour chacun des câbles, un ou généralement plusieurs balanciers élémentaires, garnis d'au moins un galet avec lequel coopère le câble correspondant, ce balancier élémentaire étant monté pivotant autour d'un axe orthogonal aux câbles sur des balanciers supports, eux-mêmes portés par une structure portante, les balanciers élémentaires, les galets, les balanciers supports des différents câbles étant placés en regard, caractérisé par le fait que les balanciers élémentaires en regard associés aux différents câbles ne sont pas reliés mécaniquement entre eux en vue de former un ensemble monobloc tel que leur pivotement symétrique soit imposé.The invention aims to remedy these drawbacks and to this end it proposes a device for holding the cables of an installation having one or more vehicles supported by at least two parallel carrying cables and tractors, of the type comprising, for each of the cables, one or generally several elementary pendulums, furnished with at least one roller with which the corresponding cable cooperates, this elementary pendulum being pivotally mounted about an axis orthogonal to the cables on support pendulums, themselves carried by a bearing structure, elementary pendulums, the rollers, the pendulums supporting the different cables being placed facing each other, characterized in that the facing elementary pendulums associated with the different cables are not mechanically connected together in order to form a monobloc assembly such that their symmetrical pivoting be imposed.

Selon une autre caractéristique de l'invention, le dispositif comporte des moyens limitant l'amplitude du pivotement des balanciers élémentaires autour de leur axe de pivotement ainsi que des moyens limitant l'amplitude du pivotement des balanciers supports autour de leur axe de pivotement.According to another characteristic of the invention, the device comprises means limiting the amplitude of the pivoting of the elementary pendulums around their pivot axis as well as means limiting the amplitude of the pivoting of the support pendulums around their pivot axis.

Par conséquent, l'invention vise à éviter d'assujettir totalement les uns aux autres les galets associés aux différents câbles. Ces galets disposent d'une certaine liberté dans leurs mouvements d'ensemble. Toutefois, ce débattement réciproque est limité. Dès lors, les contraintes sur les câbles ou leurs dispositifs de maintien sont mieux réparties.Consequently, the invention aims to avoid completely subjecting each other the rollers associated with the different cables. These rollers have a certain freedom in their overall movements. However, this reciprocal travel is limited. Consequently, the stresses on the cables or their holding devices are better distributed.

L'invention sera bien comprise grâce à la description qui suivra en référence aux dessins annexés dans lesquels :

  • La figure 1 est une vue de dessus d'un dispositif selon l'invention.
  • La figure 2 est une vue en élévation du dispositif de la figure 1.
  • La figure 3 est une vue en coupe selon la ligne 111-111 de la figure 2.
  • La figure 4 est une vue en coupe selon la ligne IV-IV de la figure 1.
The invention will be better understood from the description which follows with reference to the accompanying drawings in which:
  • Figure 1 is a top view of a device according to the invention.
  • Figure 2 is an elevational view of the device of Figure 1.
  • Figure 3 is a sectional view along line 111-111 of Figure 2.
  • Figure 4 is a sectional view along line IV-IV of Figure 1.

L'invention concerne un dispositif de maintien de câbles 1 destiné notamment à une installation de transport à câbles aériens - en particulier deux câbles porteurs et tracteurs parallèles ou sensiblement parallèles 1 a, 1 b.The invention relates to a cable holding device 1 intended in particular for an overhead cable transport installation - in particular two parallel or substantially parallel carrying cables and tractors 1 a, 1 b.

Le dispositif présente une symétrie d'ensemble par rapport à un plan P médian. Ce plan étant généralement un plan vertical dans le cas d'une installation de transport à câbles aériens.The device has an overall symmetry with respect to a median plane P. This plane is generally a vertical plane in the case of an overhead cable transport installation.

Dans la suite du texte, le dispositif sera décrit dans sa généralité sans se référer spécifiquement à un câble ou à un autre, la référence correspondante étant alors dépourvue d'indice. En revanche, lorsqu'il s'agit de se référer expressément à un organe correspondant à l'un des câbles 1 a ou 1 b, la référence correspondante sera suivie de l'indice a ou b, respectivement.In the rest of the text, the device will be described in its generality without referring specifically to one cable or another, the corresponding reference then being devoid of index. On the other hand, when it comes to expressly referring to an organ corresponding to one of the cables 1 a or 1 b, the corresponding reference will be followed by the index a or b, respectively.

Il est bien entendu que l'invention s'applique au cas d'un nombre de câbles supérieur à deux.It is understood that the invention applies to the case of a number of cables greater than two.

Le dispositif comporte, pour chacun des câbles 1, un ou plus généralement plusieurs balanciers élémentaires 2 garnis d'au moins un galet 3 pivotant autour de son axe 4 et avec lequel coopère le câble 1 correspondant. Ce balancier élémentaire 2 est monté pivotant autour d'un axe 5 orthogonal aux câbles 1 sur des balanciers supports 6 eux-mêmes portés par une structure portante 7.The device comprises, for each of the cables 1, one or more generally several elementary pendulums 2 furnished with at least one roller 3 pivoting about its axis 4 and with which the corresponding cable 1 cooperates. This elementary pendulum 2 is pivotally mounted around an axis 5 orthogonal to the cables 1 on support pendulums 6 themselves carried by a bearing structure 7.

Les balanciers élémentaires 2, galets 3, axe 4, axe 5, balanciers supports 6, et composants de la structure portante 7 associée aux différents câbles 1, sont placés en regard puisque placés dans leur ensemble symétriquement par rapport au plan P.The elementary pendulums 2, rollers 3, axis 4, axis 5, support pendulums 6, and components of the supporting structure 7 associated with the various cables 1, are placed facing each other since they are placed as a whole symmetrically with respect to the plane P.

En particulier, le balancier support 6 est également monté pivotant sur la structure portante 7 autour d'un axe 8 parallèle aux axes 4 et 5.In particular, the support pendulum 6 is also pivotally mounted on the supporting structure 7 around an axis 8 parallel to the axes 4 and 5.

Préférentiellement, un balancier élémentaire 2 d'une câble 1 comporte deux galets 3 placés à proximité immédiate l'un de l'autre, les axes 4 de ces galets étant situés aux deux parties extrêmes 9 du balancier élémentaire 2. De même, à un balancier support 6 sont associés deux balanciers élémentaires 2, les axes 5 étant situés aux parties extrêmes 10 du balancier support 6. Les deux galets 3 les plus proches associés aux deux balanciers élémentaires 2 sont placés à proximité immédiate l'un de l'autre.Preferably, an elementary balance 2 of a cable 1 comprises two rollers 3 placed in close proximity to each other, the axes 4 of these rollers being located at the two end parts 9 of the elementary balance 2. Similarly, at a support pendulum 6 are associated with two elementary pendulums 2, the axes 5 being located at the end portions 10 of the support pendulum 6. The two closest rollers 3 associated with the two elementary pendulums 2 are placed in close proximity to one another.

Dans le cas représenté sur les figures, à la structure portante 7 associée à un câble 1 sont associés deux balanciers supports 6, les axes 8 étant placés aux parties extrêmes 11 de cette structure. Dans ce cas, les galets les plus proces des deux balanciers supports 6 sont également placés au voisinnage immédiat l'un de l'autre.In the case shown in the figures, the supporting structure 7 associated with a cable 1 are associated with two support pendulums 6, the pins 8 being placed at the end portions 11 of this structure. In this case, the closest rollers of the two support pendulums 6 are also placed in the immediate vicinity of one another.

Les axes 5 et 8 sont placés dans les parties médianes respectivement du balancier élémentaire 2 et du balancier support 6.The axes 5 and 8 are placed in the middle parts of the elementary balance 2 and of the support balance 6, respectively.

Les galets 3 sont normalement identiques et constitués par des poulies à gorges.The rollers 3 are normally identical and consist of grooved pulleys.

L'invention s'applique au cas d'un balancier élémentaire 2 garni d'un nombre différent de galets 3, au cas d'un balancier support 6 garni d'un nombre différent de balanciers élémentaires 2 et au cas d'une structure portante 7 garni d'une nombre différent de balanciers supports 6. L'invention s'applique également au cas ou la structure qui vient d'être décrite (premier balancier monté pivotant par sa partie médiane à la partie extrême d'un second balancier) et multipliée de façon plus importante.The invention applies to the case of an elementary balance 2 furnished with a different number of rollers 3, to the case of a support balance 6 furnished with a different number of elementary balance 2 and to the case of a bearing structure 7 furnished with a different number of support pendulums 6. The invention also applies to the case where the structure which has just been described (first pendulum mounted to pivot by its middle part to the end part of a second pendulum) and multiplied more significantly.

Les galets 3 sont soit des galets supports, lorsque les câbles 1 sont situés au-dessus, soit des galets de compression, lorsque les câbles 1 sont situés en-dessous.The rollers 3 are either support rollers, when the cables 1 are located above, or compression rollers, when the cables 1 are located below.

Dans l'exemple illustré sur les figures, la structure portante 7 est symétrique par rapport au plan P, et extérieure à la voie de câbles 1 et les galets 3, les balanciers élémentaires 2, les balanciers supports 6 sont placés latéralement, vers l'extérieur de la structure portante 7 donc, ou à proximité ou symétriquement de part et d'autre des plans PA et PB parallèles au plan P et passant par les câbles 1a, 1 b respectivement.In the example illustrated in the figures, the supporting structure 7 is symmetrical with respect to the plane P, and external to the cable channel 1 and the rollers 3, the elementary pendulums 2, the supporting pendulums 6 are placed laterally, towards the outside of the supporting structure 7 therefore, or near or symmetrically on either side of the planes P A and P B parallel to the plane P and passing through the cables 1a, 1b respectively.

En variante, la structure 7 est centrale (non représenté).Alternatively, the structure 7 is central (not shown).

Préférentiellement, chaque balancier élémentaire 2 associé à un câble 1 est en deux parties 2', 2" placées respectivement de part et d'autre des galets 3. De même, chaque balancier associé à un câble 1 est également en deux parties 6', 6", de part et d'autre des galets 3 et à l'extérieur des parties 2' et 2" des balanciers élémentaires 2.Preferably, each elementary balance 2 associated with a cable 1 is in two parts 2 ′, 2 "placed respectively on either side of the rollers 3. Likewise, each balance associated with a cable 1 is also in two parts 6 ', 6 ", on either side of the rollers 3 and outside of the parts 2 ′ and 2" of the elementary pendulums 2.

Dans la forme de réalisation qui est représentée sur les figures, la structure portante 7 forme deux poutres latérales fixées à et portées par une super structure non représentée notamment faisant partie d'un pylône. Chaque axe 8 est fixe et s'étend de part de d'autre de la structure portante 7 en direction des plans Pa et Pb. Sur l'axe 8 sont montées les deux parties 6' et 6" d'un balancier support 10 et ceci pour chacun des câbles 1 a, 1 b. Les deux parties 6' et 6" sont écartées transversalement l'une de l'autre pour permettre le logement entre elles des parties 2' et 2" des deux balanciers élémentaires 2 et des galets 3.In the embodiment which is shown in the figures, the supporting structure 7 forms two lateral beams fixed to and carried by a super structure not shown in particular forming part of a pylon. Each axis 8 is fixed and extends on either side of the supporting structure 7 in the direction of the planes Pa and Pb. On the axis 8 are mounted the two parts 6 'and 6 "of a support pendulum 10 and this for each of the cables 1 a, 1 b. The two parts 6 'and 6 "are spaced transversely from one another to allow the accommodation between them of the parts 2" and 2 "of the two elementary pendulums 2 and of the rollers 3.

Selon l'invention, les balanciers élémentaires 2 en correspondance associés aux différentes câbles (balanciers 2a et 2b) ne sont pas reliés mécaniquement entre eux en vue de former un ensemble monobloc tel que leur pivotement symétrique soit imposé. Cette absence de liaison mécanique directe et rigide est bien visible sur la figure 1.According to the invention, the elementary pendulums 2 in correspondence associated with the different cables (pendulums 2a and 2b) are not mechanically connected together in order to form a one-piece assembly such that their symmetrical pivoting is imposed. This absence of direct and rigid mechanical connection is clearly visible in FIG. 1.

De même, selon l'invention, les balanciers supports 6 en correspondance associés aux différents câbles (c'est-à-dire les balanciers 6a et 6b) ne sont pas reliés mécaniquement entre eux en vue de former un ensemble monobloc tel que leur pivotement symétrique soit imposé. Cette caractéristique est également bien visible sur la figure 1.Similarly, according to the invention, the corresponding support pendulums 6 associated with the different cables (that is to say the pendulums 6a and 6b) are not mechanically connected together in order to form a one-piece assembly such as their pivoting symmetrical be imposed. This characteristic is also clearly visible in FIG. 1.

Selon une caractéristique essentielle de l'invention, il est prévu des moyens limitant l'amplitude du pivotement des balanciers élémentaires 2 autour de leur axe de pivotement 5. En particulier, il est prévu des moyens limitant l'amplitude du pivotement des balanciers élémentaires 2 autour de leur axe de pivotement 5 à une valeur comprise entre 0°, borne exclue, et 10°. Ces moyens limitant l'amplitude du pivotement des balanciers élémentaires 2 autour de leur axe 5 sont constitués par exemple par une pièce centrale 12 associée à/ou constituée par le balancier support 6 coopérant avec une pièce double latérale 13 formant fourche associée à/ou constituée par le balancier support 6 ou le balancier élémentaire 2. Ainsi, dans la forme de réalisation illustrée par les figures, (figure 4) la pièce centrale 12 est constituée par l'une des parties - notamment la partie interne - du balancier 2 et la pièce double la- tèrale 13 est constitué par une pièce rapportée sur le balancier support 6. Cet ensemble pièce centrale 12 et pièce double latérale 13 est écarté de l'axe 5 d'une distance ni trop importante afin que l'amplitude du pivotement soit suffisante, ni trop faible pour que cette amplitude ne soit pas trop importante et ceci avec un jeu de la pièce centrale 12 dans la pièce double latérale 13 limité. En particulier, l'ensemble pièce centrale 12 et pièce double latérale 13 est placé entre l'axe 5 du balancier élémentaire 2 et l'axe 4 d'un des galets 3 qu'il supporte. Par exemple, l'ensemble pièce centrale 12 et pièce double latérale 13 est placé à partir de l'axe 5 au tiers environ de la distance séparant l'axe 5 de l'axe 4. Le jeu entre la pièce centrale 12 et le pièce double latérale 13 est par exemple de l'ordre de quelques millimètres.According to an essential characteristic of the invention, means are provided limiting the amplitude of the pivoting of the elementary pendulums 2 about their pivot axis 5. In particular, means are provided limiting the amplitude of the pivoting of the elementary pendulums 2 around their pivot axis 5 at a value between 0 °, terminal excluded, and 10 ° . These means limiting the amplitude of the pivoting of the elementary pendulums 2 about their axis 5 are constituted for example by a central part 12 associated with / or constituted by the support balance 6 cooperating with a double lateral part 13 forming a fork associated with / or constituted by the support balance 6 or the elementary balance 2. Thus, in the embodiment illustrated by the figures, (FIG. 4) the central part 12 is constituted by one of the parts - in particular the internal part - of the balance 2 and the lateral double part 13 is constituted by an insert on the support balance 6. This central part 12 and double lateral part 13 assembly is spaced from the axis 5 by a distance that is not too great so that the amplitude of the pivoting is sufficient, nor too low so that this amplitude is not too large and this with a clearance of the central part 12 in the double lateral part 13 limited. In particular, the central part 12 and double lateral part 13 assembly is placed between the axis 5 of the elementary balance 2 and the axis 4 of one of the rollers 3 that it supports. For example, the central part 12 and double lateral part 13 assembly is placed from the axis 5 at about a third of the distance separating the axis 5 from the axis 4. The clearance between the central part 12 and the part double lateral 13 is for example of the order of a few millimeters.

Pour éviter toutes distorsions et disparités dans l'application des contraintes, il est prévu un ensemble pièce 12, pièce 13 pour chaque balancier élémentaire 2.To avoid any distortions and disparities in the application of the constraints, a part 12, part 13 assembly is provided for each elementary balance 2.

Comme indiqué précédemment, cet ensemble pièce centrale 12 et pièce double latérale 13 est placé sur la partie interne d'un balancier 2 c'est-à-dire la partie tournée vers la structure portante 7. Egalement, préférentiellement, chaque ensemble pièce centrale 12, pièce double latérale 13 est placé à la partie extrême prolongée 14 de la partie interne 6' du balancier support 6.As indicated above, this central part 12 and double lateral part 13 assembly is placed on the internal part of a pendulum 2, that is to say the part facing the bearing structure 7. Also, preferably, each central part 12, double lateral part 13 assembly is placed at the extended end part 14 of the part internal 6 'of the support balance 6.

Egalement, selon l'une des caractéristiques essentielle de l'invention, il est prévu des moyens limitant l'amplitude du pivotement des balanciers supports 6 autour de leur axe de pivotement 8. Ces moyens limitent par exemple le pivotement à une valeur comprise entre 0° borne exclue et 10°. Ces moyens sont constitués notamment par une pièce centrale 15 associée à/ou constituée par le balancier support 6 ou la structure portante 7 coopérant avec une pièce double latérale 16 formant fourche associée à/ou constituée par la structure portante 7 ou le balancier support 6.Also, according to one of the essential characteristics of the invention, means are provided limiting the amplitude of the pivoting of the support pendulums 6 about their pivot axis 8. These means limit the pivoting for example to a value between 0 ° terminal excluded and 10 ° . These means are constituted in particular by a central part 15 associated with / or constituted by the support pendulum 6 or the supporting structure 7 cooperating with a double lateral part 16 forming a fork associated with / or constituted by the bearing structure 7 or the support pendulum 6.

Dans la forme de réalisation représentée sur les figures (figure 3) la pièce centrale 15 est constituée par le balancier support 6 notamment sa partie interne 6' et la pièce double latérale 16 est constitué par une pièce rapportée sur la face latérale de la structure portante 7.In the embodiment shown in the figures (Figure 3) the central part 15 is constituted by the support pendulum 6 in particular its internal part 6 'and the double lateral part 16 is constituted by an insert on the lateral face of the supporting structure 7.

Comme vu précédemment en ce qui concerne l'ensemble pièce centrale 12, pièce double latérale 13, l'ensemble pièce centrale 15 et pièce double latérale 16 est suffisamment écarté sans l'être trop de l'axe de pivotement 8 du balancier support 6. En particulier, l'ensemble pièce centrale 15, pièce double latérale 16 est placé au voisinnage de l'extrémité du balancier support 6 notamment sensiblement symétrique de l'ensemble pièce centrale 12, pièce latérale 13 par rapport à l'axe 5.As seen above with regard to the central part 12, double lateral part 13, the central part 15 and double lateral part 16 assembly is sufficiently spaced without being too far from the pivot axis 8 of the support balance 6. In particular, the central part assembly 15, double lateral part 16 is placed in the vicinity of the end of the support balance 6 in particular substantially symmetrical with the central part assembly 12, lateral part 13 with respect to the axis 5.

Naturellement, les balanciers supports 6 sont calés axialement sur l'axe 8 tout en étant à rotation libre autour de cet axe (sauf la présence des moyens de limitation du pivotement 15, 16).Naturally, the support pendulums 6 are axially wedged on the axis 8 while being free to rotate about this axis (except for the presence of the means for limiting the pivoting 15, 16).

Que ce soit pour l'ensemble 12,13 ou pour l'ensemble 15, 16, il est clair que l'on peut envisager les variantes suivantes:

  • Présence de moyens d'amortissement de fin de course tels que butées élastiques; moyens élastiques de rappel vers une position médiane tels que des blocs élastiquement déformable; moyens de réglage de l'amplitude soit par coulissement des ensembles 12, 13, 15, 16 respectivement le long du balancier support 6 ou le long de la structure portante 7 ou encore au moyen d'une butée réglable.
Whether for the set 12,13 or for the set 15, 16, it is clear that the following variants can be envisaged:
  • Presence of end-of-travel damping means such as elastic stops; elastic means for returning to a middle position such as elastically deformable blocks; means for adjusting the amplitude either by sliding the assemblies 12, 13, 15, 16 respectively along the support pendulum 6 or along the supporting structure 7 or even by means of an adjustable stop.

L'invention concerne également une installation de transport à câbles aériens en particulier deux câbles porteurs et tracteurs parallèle s'étendant entre des stations d'extrémité et supportées par un ou plusieurs dispositif de maintien tel que celui qui vient d'être décrit, les câbles supportant supportant eux-mêmes un ou plusieurs véhicules.The invention also relates to an overhead cable transport installation, in particular two carrying cables and parallel tractors extending between end stations and supported by one or more holding devices such as the one just described, the cables supporting themselves supporting one or more vehicles.
