Abstract

A detachable gondola lift or chair-lift is disclosed which includes several sections which can operate independently from one another. Two sections are connected in an intermediate station by connecting tracks to transfer cars from one section to the other. Each section is equipped with a chain to drive the cars on the transfer rails. Each section is also fitted with flowrate regulators. When the two sections are joined, an adjustment device adjusts the chain of one of the sections in relation to the chain of the other section to achieve a regular transfer of the cars from one section to the other without intermediate storage.

Description

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

Chaque section peut fonctionner indépendamment l'une de l'autre, les passagers débarquant dans chaque station, tandis que la cabine désaccouplée du câble circule à faible vitesse sur un circuit de renvoi vers la voie de retour du câble, auquel elle st réaccouplée à la sortie de la station.Each section can operate independently of each other, passengers disembarking at each station, while the uncoupled cable cabin travels at low speed on a return circuit to the cable return channel, to which it is re-coupled to the exit the station.

Les passagers qui empruntent la section suivante, embarquent dans une cabine de cette deuxième section et ainsi de suite, chaque section fonctionnant à sa propre cadence.Passengers who take the next section embark in a cabin of this second section and so on, each section operating at its own rate.

Lors d'une connexion en série des deux sections, les cabines passent d'une section à l'autre et les deux sections fonctionnent au même débit et donc à la même cadence.When the two sections are connected in series, the cabins pass from one section to the other and the two sections operate at the same speed and therefore at the same rate.

Dans ce cas on évite un débarquement des passagers dans la ou les stations intermédiaires, la cabine passant de l'une des sections à la suivante en circulant sur une voie de liaison reliant les deux sections. Dans la station intermédiaire les cabines avancent irrégulièrement et des chocs et accumulations de cabines sont inévitables; ces chocs sont préjudiciables au matériel et aux personnes transportées et freinent le débit.In this case, passengers are disembarked at the intermediate station or stations, the cabin passing from one of the sections to the next by traveling on a connecting track connecting the two sections. In the intermediate station the cabins move irregularly and shocks and accumulations of cabins are inevitable; these shocks are detrimental to the equipment and people transported and slow down the flow.

Le document EP-A 0 114 129 de la demanderesse a fait connaître des systèmes cadenceurs évitant des chocs ou arrêts des cabines, et qui régularisent la circulation des cabines ou sièges d'une section et conservent une cadence régulière et une préparation uniforme des cabines le long du câble. Ces cadenceurs modifient automatiquement la vitesse de circulation des cabines sur un tronçon cadenceur pour rattraper un retard ou une avance de la cabine.Document EP-A 0 114 129 of the applicant disclosed timing systems preventing shocks or stopping of the cabins, and which regulate the circulation of the cabins or seats of a section and maintain a regular cadence and a uniform preparation of the cabins. along the cable. These timers automatically change the speed of movement of the cabs on a timing section to catch up with a delay or advance in the cabin.

La présent einvention a pour but de permettre l'adaptation de tels cadenceurs à une installation du type précité à plusieurs sections en série et d'assurer une circulation régulière des cabines dans les stations intermédiaires.The purpose of the present invention is to allow the adaptation of such timers to an installation of the aforementioned type with several sections in series and to ensure regular circulation of the cabins in the intermediate stations.

Ce but est atteint par la mise en oeuvre des moyens mentionnés dans la partie caractérisante de la revendication 1.This object is achieved by the implementation of the means mentioned in the characterizing part of claim 1.

Lors d'un ordre de couplage en série des sections, le dispositif de calage selon l'invention est actionné pour assurer un calage d'une section par rapport à l'autre, de telle manière qu'une cabine quittant l'une des sections arrive, après franchissement de la voie de liaison, à l'autre section au moment approprié pour une prise en charge par le système d'entraînement de cette dernière section. Le dispositif de calage assure également le synchronisme des cadenceurs des deux sections.During an order of series coupling of the sections, the wedging device according to the invention is actuated to ensure a wedging of one section relative to the other, so that a cabin leaving one of the sections arrives, after crossing the connecting track, at the other section at the appropriate time for taking over by the drive system of this last section. The timing device also ensures synchronization of the timers of the two sections.

Le décalage dépend bien entendu de la longueur et de la durée de parcours de la voie de liaison pour passer d'une section vers l'autre et cette valeur de décalage est, par exemple, déterminée par des essais.The offset depends of course on the length and the duration of travel of the connecting track to pass from one section to another and this offset value is, for example, determined by tests.

Toutes les cabines doivent arriver dans un intervalle d'écart admissible par le moyen cadenceur, lequel corrige pa la suite les écarts.All cabins must arrive within an acceptable gap interval by the clocking means, which subsequently corrects the deviations.

Le dispositif d'entraînement des cabines dans les stations peut être d'un type quelconque, par exemple à chaîne à taquets, à roues de friction ou à gravité, ces dispositifs n'étant pas forcément dans toutes les stations.The device for driving the cabins in the stations can be of any type, for example with chain with cleats, with friction or gravity wheels, these devices not necessarily being in all the stations.

Dans le cas d'une chaîne à taquets on ménage un repère sur la chaîne et on détecte le passage de ce repère à un emplacement prédéterminé, par exemple par un détecteur de proximité, un microcontact actionné par un poussoir, une cellule photoélectrique ou tout système opérant. On affiche le décalage nécessaire au bon fonctionnement et on contrôle l'écart entre le passage du repère de la première section et celui de la deuxième section, qui doit correspondre au décalage affiché.In the case of a cleat chain, a mark is provided on the chain and the passage of this mark is detected at a predetermined location, for example by a proximity detector, a microswitch actuated by a push-button, a photocell or any system. operating. The offset necessary for proper operation is displayed and the difference between the passage of the reference mark in the first section and that of the second section is checked, which must correspond to the offset displayed.

Lors d'un retard il suffit par exemple d'accélérer temporairement la chaîne d'entraînement en retard pour rétablir le calage correct d'une chaîne par rapport à l'autre ou inversement de freiner la chaîne en avance, etc... Les chaînes d'entraînement sont de préférence, mais non obligatoirement entraînées à la même vitesse, de même que les câbles aériens des différentes sections. Lorsque le mouvement d'entraînement des chaînes de transfert est dérivé de celui du câble, le dispositif de calage selon l'invention régie la vitesse du câble et de ce fait indirectement celui de la chaîne associée. Il suffit à cet effet de piloter le régulateur de vitesse du moteur principal par le dispositif de calage.During a delay, it is sufficient, for example, to temporarily accelerate the late drive chain to restore the correct timing of one chain with respect to the other or vice versa to brake the chain in advance, etc. The chains are preferably, but not necessarily driven at the same speed, as are the overhead cables of the different sections. When the drive movement of the transfer chains is derived from that of the cable, the wedging device according to the invention governs the speed of the cable and therefore indirectly that of the associated chain. For this purpose, it suffices to control the speed regulator of the main motor by the timing device.

Une section peut comporter deux moyens cadenceurs l'un dans chacune des stations de la manière décrite dans les demandes précitées, mais dans la majorité des cas un cadenceur par section est suffisant pour compenser les irrégularités. Dans ce cas le mouvement du système cadenceur est capté sur l'une des poulies d'extrémités du câble principal. La disposition des cadenceurs et des moteurs des deux sections dans la station intermédiaire facilite l'alimentation et la commande des sections.A section can include two timing devices, one in each of the stations as described in the aforementioned requests, but in the majority of cases one timer per section is sufficient to compensate for irregularities. In this case the movement of the timing system is captured on one of the end pulleys of the main cable. The arrangement of the timers and motors of the two sections in the intermediate station facilitates the feeding and control of the sections.

Selon un mode de mise en oeuvre de l'invention, le tronçon cadenceur comporte un premier moyen de propulsion des cabines par des taquets fixes de la chaîne de transfert, s'étendant le long du circuit en demi-boucle de renvoi des cabines vers la voie de retour et un deuxième moyen à roues de friction de vitesse légèrement différente. La cabine est prise en charge, après sa décélération, par l'un des taquets fixe ou effaçable de la chaîne sans arrêt notable et est acheminée à vitesse réduite vers le tronçon cadenceur, de préférence situé juste avant la zone d'accélération et d'accouplement au câble. A l'entrée du tronçon cadenceur une came relève ou efface les taquets effaçables et la cadence de sortie est imposée par les taquets fixes de la manière décrite dans les demandes de brevets précités.According to one embodiment of the invention, the timing section comprises a first means of propelling the cabins by fixed cleats of the transfer chain, extending along the half-loop circuit for returning the cabins to the return track and a second means with friction wheels of slightly different speed. The cabin is taken over, after its deceleration, by one of the fixed or erasable cleats of the chain without notable stop and is conveyed at reduced speed to the timing section, preferably located just before the acceleration and cable coupling. At the entrance to the timing section, a cam raises or clears the erasable lugs and the output rate is imposed by the fixed lugs as described in the aforementioned patent applications.

Le calage correct sur la voie montée ne correspond pas forcément à un calage correct sur la voie de descente et selon l'invention une correction correspondante est apportée par un réglage de la chaîne de transfert démunie du moyen cadenceur.The correct timing on the ascending track does not necessarily correspond to a correct timing on the descending track and according to the invention a corresponding correction is made by adjusting the stripped transfer chain of the clocking means.

D'autres avantages et caractéristiques ressortiront plus clairement de la description d'un mode de mise en oeuvre de l'invention, donné à titre d'exemple non limitatif et représenté aux dessins annexés, dans lesquels:

  • La figure 1 est une vue schématique en plan d'une télécabine à plusieurs sections selon l'invention ;
  • la figure 2 est une vue schématique en perspective d'une station intermédiaire de la figure 1 ;
  • la figure 3 est une vue en coupe d'un chariot d'une cabine engagée sur un tronçon cadenceur ;
  • la figure 4 est une coupe suivant la ligne IV-IV de la figure 3 illustrant une chaîne de transfert à taquets effaçables et fixes.
Other advantages and characteristics will emerge more clearly from the description of an embodiment of the invention, given by way of nonlimiting example and represented in the appended drawings, in which:
  • Figure 1 is a schematic plan view of a gondola with several sections according to the invention;
  • Figure 2 is a schematic perspective view of an intermediate station of Figure 1;
  • Figure 3 is a sectional view of a carriage of a cabin engaged on a timing section;
  • Figure 4 is a section along the line IV-IV of Figure 3 illustrating a transfer chain with erasable and fixed tabs.

Sur les figures une installation de transport à câble aérien, par exemple, une télécabine ou un télésiège débrayable, monocâble ou bicâble, comporte trois sections successives 10, 12, 14, seul le début de la troisième section 14 étant esquissé sur le dessin. Le nombre de sections peut être différent, notamment de deux. Les sections 10, 12, 14 sont d'un type standard ayant chacune un câble 16, 18, tracteur ou porteur, tracteur, s'étendant en boucle fermée entre deux stations aval et amont 20, 22, 24, 26 en passant sur des poulies de renvoi 28, 30, 32, 34.In the figures, an overhead cable transport installation, for example, a detachable gondola or chairlift, single or double cable, has three successive sections 10, 12, 14, only the start of the third section 14 being sketched in the drawing. The number of sections can be different, in particular two. Sections 10, 12, 14 are of a standard type each having a cable 16, 18, tractor or carrier, tractor, extending in closed loop between two downstream and upstream stations 20, 22, 24, 26 passing over return pulleys 28, 30, 32, 34.

Chaque station comporte un rail de transfert 36, 38, 40, 42 en demi-boucle reliant les deux brins du câble 16, 18. Au câble 16, 18 est accouplé par une pince 44 un chariot 46 de support par une suspente 47 d'une cabine 48, la pince 44 étant de type débrayable pour un désaccouplement du chariot 46 à l'entrée des stations 20, 26 par l'action d'une came 49 et un roulement du chariot 46 par des roues 50 sur le rail 36-42. Une chaîne 52, 54, 56, 58 à taquets s'étend le long de chaque rail 36-42 pour propulser les chariots 46 dans la station à une vitesse réduite pour l'embarquement et de débarquement des passagers. A la sortie de la station 20-26 des roues 60 de friction à pneumatique coopérent avec une piste 61 du chariot 46 pour l'accélérer à la vitesse du câble 16, 18 avant l'accouplement à ce dernier. A l'entrée de la station des roues analogues 60 peuvent freiner le chariot 46 désaccouplé du câble.Each station has a transfer rail 36, 38, 40, 42 in half-loop connecting the two strands of the cable 16, 18. To the cable 16, 18 is coupled by a clamp 44 a carriage 46 for support by a hanger 47 of a cabin 48, the clamp 44 being of the disengageable type for uncoupling the carriage 46 at the entrance to the stations 20, 26 by the action of a cam 49 and a rolling of the carriage 46 by wheels 50 on the rail 36- 42. A chain 52, 54, 56, 58 with cleats extends along each rail 36-42 to propel the carriages 46 into the station at a reduced speed for boarding and disembarking passengers. At the exit from the station 20-26, the friction wheels 60 for tires cooperate with a track 61 of the carriage 46 to accelerate it to the speed of the cable 16, 18 before coupling to the latter. At the entrance to the station, analog wheels 60 can brake the carriage 46 uncoupled from the cable.

Deux sections successives 10, 12; 12, 14 sont reliées par des voies de liaison 62, qui se raccordent par des aiguillages 64 aux rails de transfert 54, 56, 58 correspondants, pour le passage des chariots 46 d'une section vers l'autre dans le sens aller et dans le sens retour. Des roues 60 de friction sont échelonnées le long des voies de liaison 62 pour un entraînement des chariots 46.Two successive sections 10, 12; 12, 14 are connected by connecting tracks 62, which are connected by switches 64 to the corresponding transfer rails 54, 56, 58, for the passage of the carriages 46 from one section to the other in the forward direction and in the return direction. Friction wheels 60 are staggered along the connecting tracks 62 for driving the carriages 46.

Il est inutile de décrire en détail une telle installation, qui est bien connue des spécialistes et il suffit de rappeler que chaque section 10, 12, 14 peut fonctionner indépendamment l'une de l'autre, les aiguillages 64 étant alors dans la position inactive, afin de ne pas dévier les chariots 46 sur les voies de liaison 62. Les sections 10,12,14 peuvent également être couplées en série en plaçant les aiguillages 64 en position active pour transférer les chariots 46 d'une section vers la suivante tant à l'aller qu'au retour.It is unnecessary to describe in detail such an installation, which is well known to specialists, and it suffices to recall that each section 10, 12, 14 can operate independently of one another, the switches 64 then being in the inactive position. , so as not to deflect the carriages 46 on the connecting tracks 62. The sections 10, 12, 14 can also be coupled in series by placing the switches 64 in the active position to transfer the carriages 46 from one section to the next as long as on the outward journey than on the return.

Deux stations adjacentes 22, 24 de sections successives 10, 12 constituent une station intermédiaire représentée plus en détail à la figure 2. La poulie 30 du câble 16 est une poulie motrice entraînée en rotation par un moteur électrique 66 par l'intermédiaire d'un réducteur 68. Le réducteur 68 entraîne par une transmission réductrice 70, par exemple, mécanique, une poulie 72 d'entraînement de la chaîne 54 à taquets. D'une manière analogue la poulie 32 de la section 12 est entraînée par un moteur 74 et un réducteur 76, ce dernier entraînant à son tour, par une transmission réductrice 78, une poulie 80 de la chaîne 56 à taquets. Les moteurs 66, 74 sont alimentés en courant continu à vitesse réglable par des blocs d'alimentation 82, 84. Les chaînes 54, 56 tournent à vitesse démultipliée, respectivement en synchronisme des câbles 16, 18.Two adjacent stations 22, 24 of successive sections 10, 12 constitute an intermediate station shown in more detail in FIG. 2. The pulley 30 of the cable 16 is a driving pulley driven in rotation by an electric motor 66 by means of a reduction gear 68. The reduction gear 68 drives by a reducing transmission 70, for example, mechanical, a pulley 72 for driving the chain 54 with cleats. In an analogous manner the pulley 32 of section 12 is driven by a motor 74 and a reduction gear 76, the latter driving in turn, by a reduction transmission 78, a pulley 80 of the chain 56 with cleats. The motors 66, 74 are supplied with direct current at adjustable speed by power supply units 82, 84. The chains 54, 56 rotate at reduced speed, respectively in synchronism of the cables 16, 18.

Le rail 38 de la station 22 et le rail 40 de la station 24 comportent chacun un tronçon cadenceur C doté de deux moyens d'entraînement, en l'occurence des roues à friction 60 et des taquets fixes 86, représentés par des triangles sur les chaînes 54, 56. Les autres taquets 88 de la chaîne, représentés par des rectangles, sont effaçables et comportent une queue 87 coopérant avec une came d'effaçage 89 qui s'étend le long du tronçon cadenceur C.The rail 38 of the station 22 and the rail 40 of the station 24 each have a timing section C provided with two drive means, in this case friction wheels 60 and fixed cleats 86, represented by triangles on the chains 54, 56. The other tabs 88 of the chain, represented by rectangles, are erasable and include a tail 87 cooperating with an erasing cam 89 which extends along the timing section C.

La chaîne 54, 56 tourne, par exemple à une vitesse légèrement supérieure à la vitesse circonféren- cielle des roues à friction 60 et la propulsion par la chaîne est prioritaire. De tels tronçons cadenceurs C sont décrits dans les demandes de brevets précités et permettent une remise en cadence des chariots 46 à chaque passage, pour conserver une répartition régulière sans stockage de cabines en station. Un chariot 46 ayant pris un retard maximal pendant le parcours est pris en charge par un taquet fixe 86 et est entraîné à vitesse rapide sur l'ensemble du tronçon cadenceur. Un chariot 46 à avance maximale est pris en charge par un taquet effaçable 88, qui s'efface à l'entrée du tronçon cadenceur C. Le chariot 46 est alors entraîné à vitesse faible par les roues à friction 60 jusqu'au rattrapage par le taquet fixe 86 suivant, qui intervient en fin du tronçon C. Dans une position intermédiaire le rattrapage intervient durant le parcours sur le tronçon plus ou moins rapidement selon le retard ou l'avance prise par le chariot 46. Il est clair que le système cadenceur peut être d'un type différent, par exemple décrit dans les demandes de brevets précités. Les tronçons cadenceurs C sont disposés juste avant la zone d'accélération des chariots 46 en fin de parcours sur les rails 38, 40 mais il est évident que d'autres dispositions sont concevables et qu'un système cadenceur peut être disposé dans chacune des stations 20, 26.The chain 54, 56 rotates, for example at a speed slightly higher than the circumferential speed of the friction wheels 60 and the propulsion by the chain has priority. Such timing sections C are described in the aforementioned patent applications and allow a resetting of the carriages 46 at each passage, to maintain a regular distribution without storing cabins in the station. A carriage 46 having taken a maximum delay during the journey is supported by a fixed cleat 86 and is driven at high speed over the entire timing section. A carriage 46 at maximum advance is supported by an erasable cleat 88, which disappears at the entrance to the clocking section C. The carriage 46 is then driven at low speed by the friction wheels 60 until it is caught by the fixed cleat 86 following, which occurs at the end of the section C. In an intermediate position the catching up occurs during the journey on the section more or less quickly depending on the delay or the advance taken by the carriage 46. It is clear that the timing system may be of a different type, for example described in the aforementioned patent applications. The timing sections C are arranged just before the acceleration zone of the carriages 46 at the end of the journey on the rails 38, 40 but it is obvious that other arrangements are conceivable and that a timing system can be arranged in each of the stations 20, 26.

Selon la présente invention les chaînes 54, 56 à taquets portent un repère 90, 92 représenté par un losange, qui actionne au passage un micro-contact 94, 96 ou tout autre moyen de détection. Les micro-contacts 94, 96 sont reliés à un bloc comparateur 98 ayant un affichage 100 de décalage. Le bloc 98 mesure l'intervalle de temps entre les signaux émis par les micro-contacts 94, 96 et le compare à la valeur affichée de décalage pour engendrer un signal de régulation appliqué au bloc d'alimentation 84 de vitesse réglable du moteur 74. Il est facile de comprendre que les signaux des micro-contacts 94, 96 sont représentatifs du déplacement et de la position relative des chaînes 54, 56 et de ce fait de la cadence de déplacement des chariots 46 sur les sections 10, 12 et du déphasage de ces cadences.According to the present invention the chains 54, 56 with cleats carry a reference 90, 92 represented by a diamond, which actuates in passing a micro-contact 94, 96 or any other detection means. The micro-contacts 94, 96 are connected to a comparator block 98 having an offset display 100. The block 98 measures the time interval between the signals emitted by the micro-contacts 94, 96 and compares it with the displayed offset value to generate a regulation signal applied to the power supply 84 of adjustable speed of the motor 74. It is easy to understand that the signals of the microswitches 94, 96 are representative of the displacement and of the relative position of the chains 54, 56 and therefore of the rate of displacement of the carriages 46 on the sections 10, 12 and of the phase shift of these rates.

Le dispositif de calage selon l'invention fonctionne de la manière suivante :The wedging device according to the invention operates as follows:

En fonctionnement indépendant des sections 10, 12, la liaison entre le bloc comparateur 98 et le bloc d'alimentation 84 est interrompue, par ouverture d'un interrupteur 162 et les sections 10, 12 fonctionnent chacune à son propre rythme. Pour une jonction des sections il convient d'afficher au préalable la valeur correcte de décalage au bloc 100 et ce réglage initial est réalisé par des essais destinés à caler la chaîne 56 par rapport à la chaîne 54, de telle manière qu'un chariot 46 ayant un retard maximal sur la section 10, et entraîné de ce fait par un taquet fixe 86 de la chaîne 54, arrive, après passage sur la voie de liaison 62, sur la section 12 à l'instant pour être pris en charge par un taquet fixe 86 de la chaîne 56. Le passage sur le tronçon cadenceur C de la section 12 rétablit par la suite la cadence correcte. En pratique il convient de prévoir une marge de sécurité tenant compte des faibles décalages susceptibles d'intervenir pendant le parcours de la voie de liaison 62. Il est clair qu'un décalage correct pour les chariots 46 de retard maximal l'est également pour tous les autres.In independent operation of the sections 10, 12, the connection between the comparator block 98 and the power supply 84 is interrupted, by opening a switch 162 and the sections 10, 12 each operate at its own pace. For a junction of the sections, the correct offset value must be displayed beforehand in block 100 and this initial adjustment is carried out by tests intended to wedge the chain 56 relative to the chain 54, so that a carriage 46 having a maximum delay on section 10, and consequently driven by a fixed cleat 86 of the chain 54, arrives, after passage on the connecting track 62, on section 12 at the instant to be taken care of by a fixed stop 86 of the chain 56. The passage on the timing section C of the section 12 thereafter restores the correct rate. In practice, it is advisable to provide a safety margin taking into account the small offsets likely to occur during the course of the connecting track 62. It is clear that a correct offset for the carriages 46 of maximum delay is also for all others.

La valeur de décalage ayant été établie et affichée en 100 et les deux sections 10, 12 fonctionnant séparément, on ferme en un premier temps, lors d'un ordre de jonction l'interrupteur 162. Le bloc 98 mesure l'écart entre les signaux 94, 96, par exemple l'intervalle de temps ou la longueur de défilement entre la fermeture des micro-contacts et compare cet écart à la valeur affichée. Si l'écart est inférieur à la valeur affichée, le bloc 98 transmet un ordre d'accélération du moteur 74 et de ce fait de la chaîne 56, provoquant une augmentation de l'écart jusqu'à l'obtention d'un calage correct, et inversement si l'écart est supérieur à la valeur affichée. Il suffit alors de placer les aiguillages 64 en position active pour réaliser la jonction.The offset value having been established and displayed at 100 and the two sections 10, 12 operating separately, the switch 162. is closed at first during a junction order. Block 98 measures the difference between the signals 94, 96, for example the time interval or the scrolling length between the closing of the microswitches and compares this difference with the displayed value. If the deviation is less than the value displayed, the block 98 transmits an acceleration order from the motor 74 and therefore from the chain 56, causing an increase in the deviation until correct timing is obtained. , and vice versa if the difference is greater than the displayed value. It then suffices to place the switches 64 in the active position to make the junction.

On comprend que le système de régulation 94, 100 synchronise les sections 10, 12, les câbles 16, 18 ainsi que les chaînes 54, 56 tournant tous à la même vitesse. Les chaînes 54, 56 sont de plus décalées ou déphasées d'une valeur prédéterminée par affichage.It is understood that the regulation system 94, 100 synchronizes the sections 10, 12, the cables 16, 18 as well as the chains 54, 56 all rotating at the same speed. The chains 54, 56 are moreover offset or out of phase by a predetermined value by display.

Le calage et la régulation peuvent être limités aux chaînes 54, 56 si celles -ci comportent un entraînement indépendant des câbles 16, 18. Si la cadence est fixée par un autre moyen de propulsion qu'une chaîne, le calage est effectué sur cet autre moyen de propulsion. On voit que l'une des sections en l'occurence la section 10 pilote toutes les autres sections de l'installation.The timing and regulation can be limited to the chains 54, 56 if these comprise an independent drive of the cables 16, 18. If the rate is set by another means of propulsion than a chain, the setting is carried out on this other means of propulsion. We see that one of the sections in this case section 10 controls all the other sections of the installation.

Pour maintenir un calage correct sur la voie de retour il est possible de jouer sur les vitesse des chaînes 52 dépourvues de cadenceur, tous ces réglages étant effectués lors de l'installation et vérifiés périodiquement.To maintain a correct setting on the return channel, it is possible to play on the speeds of the chains 52 devoid of timer, all these adjustments being made during installation and checked periodically.
