Abstract

In a continuous cable railway, the running gear 8 of the cabins 6 bears on two supporting cables 1 which extend side by side. The permanently circulating traction cable 2 extends between the two supporting cables, the running gear 8 being coupled to this traction cable, during travel, via actuatable cable clamps 24. The cable clamps are connected to the running gear so as to be vertically movable and engage from below around the traction cable which extends at the top of the running gear and can bear on the running gear between the tensioned areas, that is to say between the supports. Consequently, the weight of the traction cable does not impose a burden on the cable clamps, and the cable clamps can adapt to the position of the traction cable, independently of the running gear. Because the running gear is supported on two supporting cables, the cableway installation is less susceptible to the influence of wind and the movement of the cabins is smoother and more stable. <IMAGE>

Description

Die Erfindung betrifft eine Seilförderanlage nach dem Oberbegriff des Patentanspruches 1.The invention relates to a cable conveyor system according to the preamble of claim 1.

Eine Seilförderanlage dieser Art ist aus der US-A-2 591 680 bekannt. Die Seilklemme, die an einem Fahrwerksrahmen angebracht ist, wird normalerweise durch einen im Fahrwerksrahmen sich abstützenden Nutzlastbehälter geschlossen gehalten. Mit dem unterhalb der Last verlaufenden Zugseil wird die Seilklemme demnach gekuppelt gehalten, solange das Gewicht des Nutzlastbehälters sowie seines Inhaltes vom Fahrwerksrahmen aufgenommen wird. In den Stationen sind Kulisen vorgesehen, die durch Anheben des Nutzlastbehälters relativ zum Fahrwerksrahmen auch das Oeffnen der Klemmbacken unter der Einwirkung vorgespannter Federn zulassen. Das Anheben des Nutzlastbehälters erfolgt über an diesem befestigte Rollen, die auf den Kulissen auflaufen. Eine Seilförderanlage dieser Art ist bei Materialtransportbahnen mit begrenzten Fahrgeschwindigkeiten zweckmässig.A cable conveyor of this type is known from US-A-2 591 680. The cable clamp, which is attached to a chassis frame, is normally kept closed by a payload container supported in the chassis frame. Accordingly, the cable clamp is kept coupled with the pulling cable running below the load, as long as the weight of the payload container and its contents are absorbed by the chassis frame. Curves are provided in the stations which, by lifting the payload container relative to the chassis frame, also allow the jaws to be opened under the action of pre-tensioned springs. The payload container is lifted using rollers attached to it, which run onto the scenes. A cable conveyor system of this type is useful for material transport tracks with limited travel speeds.

Insbesondere im Bereich der Sportbahnen hat die Leistungsfähigkeit der Seilförderanlagen in den letzten Jahrzehnten entsprechend der Breitenentwicklung des Skisports wie auch des Bergtourismus insgesamt eine bemerkenswerte Steigerung erfahren. Dieser Entwicklung sind auch die Umlaufbahnen durch Vergrösserung der Förderkapazität und der Fahrgeschwindigkeit gefolgt, indem die konventionellen Systeme, d.h. Einseilbahnen und Zweiseilbahnen durch die höheren Beanspruchungen entsprechende Auslegung verstärkt wurden. Jedoch hat es sich gezeigt, dass der Leistungssteigerung auf der Grundlage der konventionellen Systeme unter Aufrechterhaltung der Anforderungen an die Sicherheit Grenzen gesetzt sind und der Komfort für die Benutzer eher abnimmt.Especially in the area of sports tracks, the performance of the cable conveyor systems has seen a remarkable increase over the past few decades in line with the broad development of skiing and mountain tourism. This development has also followed the orbits by increasing the conveying capacity and the driving speed by using the conventional systems, ie single cable cars and Cable cars were reinforced by the design corresponding to the higher demands. However, it has been shown that there is a limit to the increase in performance based on the conventional systems while maintaining the safety requirements, and the comfort for the users tends to decrease.

Aufgabe der vorliegenden Erfindung ist es deshalb, eine Seilförderanlage zu schaffen, welche gleichzeitig eine Erhöhung der Sicherheit und des Komfortes durch Verbesserung der Stabilität und der Laufruhe gewährleistet.The object of the present invention is therefore to provide a cable conveyor system which at the same time ensures an increase in safety and comfort by improving stability and smoothness.

Die erfindungsgemässe Aufgabe wird durch die Merkmale des Kennzeichens von Anspruch 1 gelöst.The object of the invention is achieved by the features of the characterizing part of claim 1.

Zusätzlich zu der durch die Abstützung der Laufwerke an beiden Tragseilen gewonnenen Stabilität wirkt auch das zwischen diesen sich an den Laufwerken angreifende Gewicht des Zugseiles stabilisierend. Die Beweglichkeit der Klemmen in der Höhe macht es möglich, den Höhenverlauf des Zugseiles relativ zu jenem der Tragseile zu verändern, was insbesondere in den Stationen von Bedeutung ist, wenn die Laufwerke vom Zugseil getrennt bzw. mit diesem wieder verbunden werden müssen. Durch die bewegliche Anordnung der Klemmen relativ zu den Laufwerken bedarf es demnach keiner Auslenkung der Fahrzeuge und es muss nur die im Verhältnis dazu geringe Klemmenmasse bewegt werden.In addition to the stability gained by supporting the drives on both support cables, the weight acting on the drives between them also acts stabilizing the pull rope. The mobility of the clamps in height makes it possible to change the height of the traction cable relative to that of the support cables, which is particularly important in the stations when the drives have to be separated from the traction cable or connected to it again. Due to the movable arrangement of the clamps relative to the drives, there is therefore no need to deflect the vehicles and only the relatively small clamp mass has to be moved.

Es ist vorteilhaft, wenn das Zugseil oberhalb der Laufwerke 8 verläuft und die Seilklemmen das Zugseil von unten umgreifen. Dies ermöglicht, das Zugseil in den Stationen oberhalb der Laufwerke bzw. Fahrzeuge zu führen, d.h. umzulenken bzw. anzutreiben und damit im Stationsgebäude Platz zu sparen.It is advantageous if the pull cable runs above the drives 8 and the cable clamps grip around the pull cable from below. This makes it possible to guide the pull rope in the stations above the drives or vehicles, i.e. to redirect or drive and thus save space in the station building.

Vorzugsweise sind die erfindungsgemässen Laufwerke mit Abstützungen für das Zugseil versehen, die zweckmässig vor und hinter den Seilklemmen angeordnet sind. Die Seilklemmen werden mithin von der Aufgabe befreit, innerhalb der Spannfelder die Last des durchhängenden Zugseils aufzunehmen und auf die Laufwerke zu übertragen.The drives according to the invention are preferably provided with supports for the traction cable, which are expediently arranged in front of and behind the cable clamps. The rope clamps are therefore relieved of the task of taking up the load of the slack pulling rope within the span and transferring it to the drives.

Vorzugsweise sind die Abstützungen für das Zugseil am Laufwerk so angeordnet, dass die entsprechenden Abstützkräfte möglichst ohne Beanspruchung anderer Teile über die Laufrollen unmittelbar auf die Tragseile übertragen werden.The supports for the traction cable are preferably arranged on the running gear in such a way that the corresponding supporting forces are transmitted directly to the supporting cables via the rollers, if possible without stressing other parts.

Die Erfindung ist nachfolgend im Rahmen eines eine 3-Seil-Umlaufbahn betreffenden Ausführungsbeispieles und unter Bezugnahme auf die beiliegenden Zeichnungen näher erläutert. Es zeigen:

Wie aus Fig. 1 ersichtlich ist, weist die beispielsweise als Kabinenbahn ausgebildete Umlaufbahn mehrere Tragseile und mindestens ein im Betrieb dauernd umlaufendes Zugseil auf. Konkret ist in Fig. 1 eine Ausführung mit zwei Tragseilen und einem Zugseil dargestellt, wobei die Tragseile mit 1 und das Zugseil mit 2 bezeichnet sind. Dabei ist das Zugseil 2 mittig zwischen den beiden Tragseilen 1 angeordnet, die auf gleicher Höhe horizontal distanziert verlaufend gespannt sind. Das Zugseil 2 verläuft in den Spannfeldern über mehrere Rollen 4 von allgemein mit 3 bezeichneten V-förmigen Zwischenabstützungen, die an den Tragseilen 1 von unten festgeklemmt sind und diese andererseits starr miteinander verbinden.As can be seen from FIG. 1, the orbit, for example designed as a cable car, has a plurality of supporting ropes and at least one traction rope which is continuously rotating during operation. Specifically, an embodiment with two suspension ropes and a pull rope is shown in FIG. 1, the suspension ropes being designated 1 and the suspension rope 2. The pull rope 2 is arranged centrally between the two support ropes 1, which are stretched horizontally at the same height and at a distance. The traction cable 2 runs in the tensioning fields over a plurality of rollers 4 of V-shaped intermediate supports, generally designated 3, which are clamped onto the support cables 1 from below and, on the other hand, rigidly connect them to one another.

Mit 5 ist allgemein ein Fahrzeug der Seilförderanlage bezeichnet, dessen Kabine 6 über ein Gehänge 7 an einem Laufwerk 8 abgestützt ist. Die Ausgestaltung des ebenfalls erfindungsgemässen Laufwerkes 8 ist in den Fig. 2 - 6 mehr im Detail dargestellt und nachfolgend näher beschrieben.5 generally designates a vehicle of the cable conveyor system, the cabin 6 of which is supported on a carriage 8 via a hanger 7. The design of the drive 8, also according to the invention, is shown in more detail in FIGS. 2-6 and described in more detail below.

Ein im Querschnitt kastenförmiger Längsträger 9 besitzt seinen beiden Enden benachbart und an Laschen 10 starr befestigt je zwei Zapfen 11, deren Achsen alle in einer gemeinsamen horizontalen Ebene liegen. Die Zapfen 11 beider Trägerenden greifen je in ein elastisches Element 12 bzw. 12ʹ ein, welche Elemente in einem gabelförmigen Arm 13 angeordnet sind. Jeder der beiden Arme 13 ist starr mit einem U-förmigen Querträger 14 verbunden, jedoch gestatten die elastischen Elemente 12 und 12ʹ eine beschränkte Bewegung der Querträger 14 in allen Richtungen relativ zum Längsträger 9 und insbesondere eine voneinander unabhängige Verschwenkung der Querträger um die Längsachse des Längsträgers 9. Die Teile 9 bis 14 bilden somit zusammen einen Rahmen 15 des Laufwerkes 8, der um eine in Längsrichtung verlaufende Achse verwindbar ist.A cross-sectionally longitudinal member 9 has its two ends adjacent and rigidly fastened to tabs 10, two pins 11 each, the axes of which all lie in a common horizontal plane. The pins 11 of both carrier ends each engage in an elastic element 12 or 12ʹ, which elements are arranged in a fork-shaped arm 13. Each of the two arms 13 is rigidly connected to a U-shaped cross member 14, however, the elastic elements 12 and 12ʹ allow limited movement of the cross member 14 in all directions relative to the side member 9 and in particular an independent pivoting of the cross member about the longitudinal axis of the side member 9. The parts 9 to 14 thus together form a frame 15 of the drive 8, which is twistable about an axis running in the longitudinal direction.

Wie aus Fig. 3 ersichtlich ist, sind an jedem der Querträger 14 über Achsen 16 je zwei Wippen 17 bzw. 18 schwenkbar befestigt, von denen jede zwei drehbar gelagerte Laufrollen 19 aufweist. Die Laufrollenpaare jeder der Wippen 17 bzw. 18 eines Querträgers 14 sind im gleichen Abstand wie die Tragseile 1, bzw. in den Stationen diesen entsprechende Tragschienen 1ʹ (Fig. 4) voneinander angeordnet.As can be seen from FIG. 3, two rockers 17 and 18 are pivotally attached to each of the cross members 14 via axes 16, each of which has two rotatably mounted rollers 19. The pairs of rollers of each of the rockers 17 and 18 of a cross member 14 are arranged at the same distance from one another as the supporting ropes 1, or in the stations corresponding supporting rails 1ʹ (FIG. 4).

Die Wippen 18 der in Fahrrichtung vorderen Laufrollenpaare sind im Unterschied zu den Wippen 17 mit Reibschuhen 20 ausgestattet, an denen in den Stationen angetriebene Reibräder 21, wie in Fig. 4 angedeutet, zur Einwirkung gebracht werden können, um die vom Zugseil abgekoppelten Fahrzeuge 5 in bekannter Weise zu bewegen bzw. zu beschleunigen oder zu verzögern. Jeweils auf dem mit 12ʹ bezeichneten Innern der beiden elastischen Elemente sitzt in jedem der gabelförmigen Arme 13 eine weitere Laufrolle 22. Die beiden Laufrollen 22 stellen Hilfsräder des Fahrzeuges 5 bzw. Laufwerkes 8 für die Kurvenfahrt insbesondere in der Berg- bzw. Talstation der Anlage dar und wirken dort mit einer Umlenkschiene 23 (Fig. 4) zusammen, die die Tragschienen 1ʹ in den Kurven ersetzt.In contrast to the rockers 17, the rockers 18 of the pairs of front rollers in the direction of travel have friction shoes 20 equipped, on which in the stations driven friction wheels 21, as indicated in FIG. 4, can be brought into effect in order to move or accelerate or decelerate the vehicles 5 uncoupled from the traction rope in a known manner. In each of the fork-shaped arms 13 there is a further roller 22 on the inside of the two elastic elements denoted by 12 Die. The two rollers 22 represent auxiliary wheels of the vehicle 5 or drive 8 for cornering, in particular in the top or bottom station of the system and there cooperate with a deflection rail 23 (FIG. 4), which replaces the mounting rails 1ʹ in the curves.

Wie aus den Fig. 2 und 3 ersichtlich ist, weist das Laufwerk 8 zwei in Längsrichtung zwischen den Armen 13 angeordnete Seilklemmen 24 auf. Jede der Seilklemmen 24 umfasst ein Klemmengehäuse 25, in welchem über eine dieses durchsetzende Achse 26 zwei Klemmenteile 27 und 28 schwenkbar gelagert sind. Jeder der Klemmenteile 27 und 28 umfasst eine Klemmbacke 27a bzw. 28a, einen geschweiften, sich seitlich über die Wippen 17, 18 hinaus erstreckenden Klemmenhebel 27b bzw. 28b und eine am freien Ende des letzteren angebrachte Betätigungsrolle 27c bzw. 28c. Dabei sind die Klemmenhebel 27 und 28 als Bügel ausgebildet, wobei zwischen den Schenkeln des Klemmenhebels 27b die Klemmenbacke 28a und der Klemmenhebel 28b angeordnet sind. Zwischen den Schenkelpaaren der beiden Klemmenhebel ist schliesslich ein Tellerfederpaket 29 angeordnet, das am Hebel 27b über einen Zapfen 27d und am Hebel 28b über einen Zapfen 28d gelenkig abgestützt ist. Wie aus der Lage des Zapfens 28b in den Fig. 4 (Klemme offen) und 5 (Klemme geschlossen) ersichtlich ist, stellt dieser Teil eines Kniehebelgelenkes dar, das bei der Oeffnungs- bzw. Schliessbewegung der Klemmbacken 27a, 28a entgegen der Wirkung des die Klemmkraft aufbringenden Tellerfederpaketes 29 eine Totpunktlage überfährt. In der offenen Lage der Klemmenteile 27 und 28 liegen diese an nicht dargestellten Anschlägen am Gehäuse 25 an.As can be seen from FIGS. 2 and 3, the drive 8 has two cable clamps 24 arranged in the longitudinal direction between the arms 13. Each of the cable clamps 24 comprises a clamp housing 25 in which two clamp parts 27 and 28 are pivotably mounted via an axis 26 passing through them. Each of the clamping parts 27 and 28 comprises a clamping jaw 27a or 28a, a curly clamping lever 27b or 28b which extends laterally beyond the rockers 17, 18 and an actuating roller 27c or 28c attached to the free end of the latter. The clamp levers 27 and 28 are designed as brackets, the clamp jaw 28a and the clamp lever 28b being arranged between the legs of the clamp lever 27b. Finally, a plate spring assembly 29 is arranged between the pair of legs of the two clamp levers, which is supported in an articulated manner on the lever 27b by means of a pin 27d and on the lever 28b by means of a pin 28d. As can be seen from the position of the pin 28b in FIGS. 4 (clamp open) and 5 (clamp closed), this represents part of a toggle joint which is used in the opening or Closing movement of the clamping jaws 27a, 28a passes over a dead center position counter to the action of the plate spring assembly 29 applying the clamping force. In the open position of the clamp parts 27 and 28, they rest on stops (not shown) on the housing 25.

Erfindungsgemäss sind die Seilklemmen 24 nicht starr sondern beweglich mit dem Rahmen 15 verbunden, wobei die Beweglichkeit unabhängig von der Oeffnungs- bzw. Schliessbewegung der Klemmbacken ist. Hierzu sind die Klemmengehäuse 25 über an einander abgekehrten Seiten angebrachte Laschenpaare 25a je mit einem Lenker 30 (Fig. 2) gelenkig verbunden, der seinerseits mittels zwei voneinander distanzierten Stangen 30a in zwei elastische Büchsen 31 eingreift. Die elastischen Büchsen 31 sind auf gleicher Höhe beidseitig der vertikalen Mittelebene des Fahrzeuges in den Querträgern 14 eingesetzt. Mithin sind die beiden Seilklemmen 24 voneinander unabhängig über die relativ zu den Querträgern 14 auslenkbaren Lenker 30 in begrenztem Ausmass axial und vertikal beweglich, wobei die Klemmbacken 27a, 28a, die das Zugseil 2 von unten umgreifen, sich quer zur vertikalen Beweglichkeit öffnen und schliessen. Es bleibt noch nachzutragen, dass zwischen den Lenkern 30 und den Klemmengehäusen 25 bzw. deren Laschenpaaren 25a nicht dargestellte weitere elastische Elemente eingeschaltet sind, die in der normalen Arbeitslage der Lenker 30 die Achse 26 der Klemmbacken 27a, 28a parallel zur Fahrzeuglängsachse und damit zum Zugseil 2 halten, um dieses letztere beim Schliessvorgang axial ausgerichtet zu erfassen.According to the invention, the cable clamps 24 are not rigidly but movably connected to the frame 15, the mobility being independent of the opening or closing movement of the clamping jaws. For this purpose, the terminal housings 25 are each articulated via a pair of tabs 25a, which are arranged on mutually facing sides, with a link 30 (FIG. 2), which in turn engages in two elastic bushes 31 by means of two rods 30a spaced apart from one another. The elastic bushes 31 are inserted at the same height on both sides of the vertical median plane of the vehicle in the cross members 14. Consequently, the two cable clamps 24 can be moved axially and vertically to a limited extent independently of one another via the links 30 which can be deflected relative to the cross beams 14, the clamping jaws 27a, 28a, which embrace the traction cable 2 from below, open and close transversely to the vertical mobility. It remains to be added that between the links 30 and the clamp housings 25 or their pairs of tabs 25a, additional elastic elements, not shown, are switched on, which in the normal working position of the links 30 have the axis 26 of the clamping jaws 27a, 28a parallel to the longitudinal axis of the vehicle and thus to the traction rope Hold 2 to grasp the latter axially aligned during the closing process.

Wie aus Fig. 4 und 5 deutlich ersichtlich ist, trägt das Klemmengehäuse 25 jeder Seilklemme 24 eine Verstellrolle 25b, über welche die Lage derselben beeinflusst werden kann. In den Stationen sind Betätigungsschienen (nicht dargestellt) vorgesehen, um über die Betätigungsrollen 27c und 28c die Klemmbacken 27a, 28a zu öffnen (bzw. zu schliessen). Den für das Oeffnen vorgesehenen Betätigungsschienen in Fahrrichtung nachgeschaltet bzw. jenen für das Schliessen vorgeschaltet, beginnt in den Stationen je eine Kulisse 36, welche die Klemmen 24 im geöffneten Zustand der Klemmenbacken 27a, 28a vermittels der Verstellrolle 25b aus dem Höhenbereich des Zugseiles 2 absenkt bzw. in diesen abhebt.As can clearly be seen from FIGS. 4 and 5, the clamp housing 25 of each cable clamp 24 carries an adjustment roller 25b, via which the position of the same can be influenced. Actuating rails (not shown) are provided in the stations in order to open (or close) the clamping jaws 27a, 28a via the actuating rollers 27c and 28c. Downstream of the actuating rails provided for the opening in the direction of travel or upstream of those for the closing, a backdrop 36 begins in the stations, which, when the clamping jaws 27a, 28a are open, lowers the clamps 24 from the height range of the pulling cable 2 by means of the adjusting roller 25b takes off in this.

Die tiefste Lage des Zugseiles 2 bezüglich des Laufwerkes 8 ist durch Auflager 32 definiert, die an den Querträgern 14 starr angebracht sind und die nach abwärts gerichteten resultierenden Zugseilkräfte über die Laufrollen 19 möglichst unmittelbar auf die Tragseile 1 übertragen.The lowest position of the traction cable 2 with respect to the carriage 8 is defined by supports 32 which are rigidly attached to the cross members 14 and which transmit the resulting downward traction cable forces as directly as possible to the support cables 1 via the rollers 19.

Am Längsträger 9 ist etwa in dessen Längsmitte ein seitlich nach aussen abstehender Ausleger 33 starr befestigt, der, wie aus den in Fig. 4 und 5 ersichtlich, jochförmig ausgebildet ist. Der Ausleger 33 übergreift das benachbarte Tragseil 1 im Abstand und trägt an seinem nach abwärts gerichteten freien Ende 33a einen parallel zu den Zapfen 11 verlaufenden Lagerbolzen 34, der eine Schwenkachse 34a des Gehänges 7 definiert. Am oberen Ende des Gehänges 7 ist, wie aus Fig. 5 ersichtlich, ein Lagerauge 7a angebracht, das vom Lagerbolzen 34 durchsetzt ist. Durch die jochförmige Ausgestaltung des Auslegers 33 ist es möglich, die von der Last resultierenden Kräfte unmittelbar auf der Höhe der Tragseile 1 in das Laufwerk 8 einzuleiten, wie auch das Zugseil 2 auf dieser Höhe am Laufwerk angreift. Der Vollständigkeit halber sei erwähnt, dass das Gehänge 7 mit dem Ausleger 33 zusätzlich über ein nicht dargestelltes Dämpfungselement so verbunden sein kann, dass Pendelbewegungen der Kabine 6 um die Schwenkachse 34a gedämpft werden.On the longitudinal beam 9, a cantilever 33 which projects laterally outwards is rigidly fastened approximately in the longitudinal center thereof and, as can be seen in FIGS. 4 and 5, is yoke-shaped. The boom 33 overlaps the adjacent support cable 1 at a distance and carries at its downward free end 33a a bearing bolt 34 which runs parallel to the pin 11 and which defines a pivot axis 34a of the hanger 7. At the upper end of the hanger 7, as shown in FIG. 5, a bearing eye 7a is attached, which is penetrated by the bearing pin 34. The yoke-shaped configuration of the boom 33 makes it possible to introduce the forces resulting from the load into the carriage 8 directly at the level of the supporting ropes 1, just as the traction rope 2 engages the carriage at this height. For the sake of completeness, that the hanger 7 can also be connected to the boom 33 via a damping element (not shown) such that pendulum movements of the cabin 6 about the pivot axis 34a are damped.

Im Ein- bzw. Ausfahrbereich der Stationen verläuft das über Niederhalte- oder Hochhalterollen einlaufende oder auslaufende Zugseil 2 parallel zu den Schienen 1ʹ, wobei auf der Einfahrseite in einem ersten Abschnitt das Abkoppeln der Fahrzeuge bzw. das Oeffnen der Klemmbacken 27a, 28a und in einem nachfolgenden zweiten Abschnitt das Bewegen der Klemmen 24 vermittels der an den Rollen 25b angreifenden Kulissen in die in Fig. 4 dargestellte abgesenkte Lage erfolgt. In der abgesenkten Lage können die Klemmbacken 27a, 28a ohne Kollisionsgefahr an einer Seilführungsrolle 36 für das Zugseil 2 vorbeigeführt werden, die in Fig. 4 angedeutet ist und an welcher eine Umlenkung des Seiles schräg nach aufwärts über die Umlaufebene der Laufwerke erfolgen kann.In the entry or exit area of the stations, the pulling rope 2 entering or leaving via hold-down or holding-up rolls runs parallel to the rails 1ʹ, with the decoupling of the vehicles or the opening of the clamping jaws 27a, 28a and in one in a first section on the entry side subsequent second section, the clamps 24 are moved into the lowered position shown in FIG. 4 by means of the links acting on the rollers 25b. In the lowered position, the clamping jaws 27a, 28a can be guided past a rope guide roller 36 for the pull rope 2 without risk of collision, which is indicated in FIG. 4 and on which the rope can be deflected obliquely upwards over the revolving plane of the drives.

Zwischen dem Einlaufbereich und dem Auslaufbereich einer Station werden die Klemmen durch die auf die Lenker 30 wirkenden federelastischen Büchsen 31 in der Lage einer Ruhelage gehalten bis sie im entsprechenden Abschnitt des Auslaufbereiches von einer Kulisse wieder auf die Höhe des Zugseiles 2 angehoben werden.Between the entry area and the exit area of a station, the clamps are held in a rest position by the spring-elastic bushes 31 acting on the handlebars 30 until they are raised again to the level of the pulling rope 2 in the corresponding section of the exit area by a link.

Andererseits könnten bei der erfindungsgemässen Seilförderanlage die beiden Tragseile auch durch Tragseilpaare ersetzt werden, um die Stabilität und/oder die Tragkraft zu erhöhen.On the other hand, in the cable conveyor system according to the invention, the two support cables could also be replaced by support cable pairs in order to increase the stability and / or the load capacity.
