Description

Die Erfindung betrifft einen Aufzug, insbesondere einen Außenaufzug.The invention relates to an elevator, in particular an external elevator.

Außenaufzüge kommen beispielsweise auf Baustellen des Hochbaus zum Einsatz, um Personen und Material in die oberen Etagen des zu bauenden oder zu sanierenden Gebäudes zu transportieren.Exterior lifts are used, for example, on construction sites of building construction to transport people and material in the upper floors of the building to be built or renovated.

Solche Außenaufzüge weisen regelmäßig eine Führung auf, die an einer der Wände des Gebäudes befestigt ist und sich somit regelmäßig in senkrechter Richtung erstreckt. Die Führung besteht aus einem oder zwei Masttürmen, an dem/denen ein Fahrkorb verfahrbar befestigt ist. Der Fahrkorb dient der Aufnahme der zu befördernden Personen oder des zu befördernden Guts.Such external lifts regularly have a guide which is fastened to one of the walls of the building and thus extends regularly in the vertical direction. The guide consists of one or two mast towers on which a car is movably mounted. The car serves to accommodate the persons to be transported or the goods to be transported.

Die Masttürme dienen somit der Führung der Bewegung des Fahrkorbs, wobei diese auch einen Teil des Antriebsstrangs darstellen können. In der Regel ist hierfür zumindest einer der Masttürme mit zumindest einer Zahnstange versehen, die sich in längsaxialer Richtung der Führung erstreckt und in die ein Ritzel eines elektrischen Fahrantriebs eingreift. Bei solchen Aufzügen ist der Fahrantrieb somit im Bereich des Fahrkorbs untergebracht und wird demnach mit dem Fahrkorb mitbewegt.The mast towers thus serve to guide the movement of the car, which may also represent a part of the drive train. As a rule, for this purpose at least one of the mast towers is provided with at least one toothed rack which extends in the longitudinal axial direction of the guide and in which a pinion of an electric traction drive engages. In such elevators, the travel drive is thus accommodated in the area of the car and is thus moved along with the car.

Aufgrund der nicht unerheblichen Leistung des Fahrantriebs solcher Aufzüge werden diese nahezu ausnahmslos über Kabel mit elektrischer Energie versorgt. Bei einem mit dem Fahrkorb mitgeführten Fahrantrieb muss das Kabel somit eine ausreichende Länge aufweisen, um ein Verfahren des Fahrkorbs bis zu seiner höchsten Position an der Führung zu erlauben. Viele Aufzüge erreichen jedoch Führungshöhen von bis zu mehreren hundert Metern, was große Anforderungen an die Lagerung und Führung des Kabels stellt. Insbesondere muss das Kabel sicher im Bereich einer Bodenstation des Aufzugs gelagert werden, wenn der Fahrkorb sich in einer Position relativ weit unten an der Führung befindet. Hierbei müssen teilweise mehrere hundert Meter Kabel platzsparend und in einer Weise gelagert werden, die ein problemloses Verlängern bzw. Verkürzen des die Bodenstation mit dem Fahrkorb verbindenden Kabelabschnitts möglich machen. Ein solches Verlängern und Verkürzen muss dabei in einer Vielzahl von Zyklen möglich sein, ohne das Kabel zu beschädigen und ohne dass sich das Kabel verfängt oder ineinander verschlingt. Zudem sollte eine unkontrollierte Kabelbewegung im Bereich der Bodenstation des Aufzugs vermieden werden.Due to the not inconsiderable performance of the drive of such elevators, these are almost invariably supplied via cables with electrical energy. In a car drive carried along with the car, the cable must therefore be of sufficient length to allow the car to move to its highest position on the guide. However, many elevators reach heights of up to several hundred meters, which places great demands on the storage and management of the cable. In particular, the cable must be safely stored in the area of a ground station of the elevator when the car is in a position relatively far down the guide. In some cases, several hundred meters of cable must be stored in a space-saving manner and in a manner that makes possible a problem-free lengthening or shortening of the cable section connecting the ground station to the car. Such lengthening and shortening must be possible in a variety of cycles, without damaging the cable and without the cable getting caught or intertwined. In addition, an uncontrolled cable movement in the area of the ground station of the elevator should be avoided.

In vielen Fällen werden die Kabel einfach mehr oder weniger gleichförmig in einem runden, nach oben offenen Kabelbehälter, auch Kabeltopf genannt, abgelegt.In many cases, the cables are simply more or less uniformly stored in a round, open-topped cable container, also called a cable tray.

Bekannt ist auch, insbesondere bei Aufzügen mit einer relativ hohen Führung, sogenannte Kabelwagen einzusetzen, die ebenfalls an der Führung geführt sind und eine Umlenkrolle aufweisen, über die das Kabel geführt ist. Der von der Bodenstation kommende Abschnitt des Kabels wird auf ca. halber Höhe der Führung fixiert. Der Abschnitt zwischen der Fixierung und dem Fahrkorb weist eine Länge auf, die ein Erreichen der höchsten und niedrigsten Haltepositionen an der Führung durch den Fahrkorb ermöglicht. Der in Abhängigkeit von dem jeweiligen Abstand zwischen der Fixierung und dem Fahrkorb überschüssige Abschnitt des Kabels ist in einer Schlaufe über die Umlenkrolle des Kabelwagens geführt. Der Kabelwagen ist ebenfalls an der Führung des Aufzugs geführt, wobei sich dieser stets unterhalb des Fahrkorbs befindet und dessen Bewegung mit halber Geschwindigkeit folgt. Dabei befindet sich der Kabelwagen direkt unterhalb des Fahrkorbs, wenn sich dieser in der Bodenstation befindet und auf ca. halber Höhe der Führung, wenn der Fahrkorb seine höchste Position an der Führung erreicht hat. Unvorteilhaft dabei ist, dass der Fahrkorb an seiner Haltestelle in der Bodenstation in einer erhöhten Position anhalten muss, um nicht mit dem darunter liegenden Kabelwagen zu kollidieren. Ein Be- und Entladen des Aufzugs muss somit über eine vergleichsweise hohe Einstiegsschwelle erfolgen.It is also known, especially in elevators with a relatively high guide, to use so-called cable cars, which are also guided on the guide and have a deflection roller over which the cable is guided. The section of the cable coming from the ground station is fixed at approximately half the height of the guide. The portion between the fixation and the car has a length that allows reaching the highest and lowest hold positions on the car's track. The depending on the respective distance between the fixation and the car excess portion of the cable is guided in a loop over the pulley of the cable cart. The cable car is also guided on the guide of the elevator, this is always below the car and follows its movement at half speed. In this case, the cable car is located directly below the car when it is in the ground station and at about half the height of the guide when the car has reached its highest position on the guide. A disadvantage is that the car must stop at its stop in the ground station in an elevated position so as not to collide with the underlying cable car. Loading and unloading of the elevator must therefore take place over a comparatively high entry threshold.

Ausgehend von diesem Stand der Technik lag der Erfindung die Aufgabe zugrunde, einen verbesserten Aufzug anzugeben. Insbesondere sollte ein gattungsgemäßer Aufzug angegeben werden, dessen Einstiegsschwelle möglichst niedrig ist.Based on this prior art, the present invention seeks to provide an improved elevator. In particular, a generic elevator should be specified whose entry threshold is as low as possible.

Diese Aufgabe wird durch einen Aufzug gemäß dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Ausführungsformen des erfindungsgemäßen Aufzugs sind Gegenstand der abhängigen Ansprüche und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.This object is achieved by a lift according to independent claim 1. Advantageous embodiments of the elevator according to the invention are the subject of the dependent claims and will become apparent from the following description of the invention.

Der Erfindung liegt der Gedanke zugrunde, die Einstiegsschwelle bei einem gattungsgemäßen Aufzug, der (mindestens) eine Führung, (mindestens) einen an der Führung geführten Fahrkorb, (mindestens) ein entlang der Führung zu dem Fahrkorb geführtes Kabel und (mindestens) einen, der Bewegung des Fahrkorbs folgenden Kabelwagen mit (mindestens) einer Umlenkvorrichtung, über den das Kabel geführt ist, aufweist, dadurch abzusenken, dass der Kabelwagen nicht unterhalb des Fahrkorbs angeordnet ist, wenn sich der Fahrkorb in einer Bodenstation des Aufzugs befindet. Vielmehr ist erfindungsgemäß vorgesehen, dass sich das untere Ende des Kabelwagens auf derselben Höhe oder oberhalb des unteren Endes des Fahrkorbs befindet, wodurch vermieden wird, das der Kabelwagen ein vollständiges Absenken des Fahrkorbs an der Führung verhindert.The invention is based on the idea of the entry threshold in a generic elevator, the (at least) one guide, (at least) one guided on the guide car, (at least) along the guide to the car guided cable and (at least) one, the Movement of the car following cable carriage with (at least) a deflection device over which the cable is guided, to lower, characterized in that the cable cart is not located below the car when the car is in a ground station of the elevator. Rather, the invention provides that the lower end of the cable cart is at the same height or above the lower end of the car, thereby avoiding the cable car prevents complete lowering of the car on the guide.

Die erfindungsgemäße Lösung zur Absenkung der Einstiegsschwelle bei einem gattungsgemäßen Aufzug kann durch eine weitgehend beliebige Konstruktion gelöst werden, die verhindert, dass der Fahrkorb und der Kabelwagen kollidieren würden, bevor der Fahrkorb die gewünschte unterste Position an der Führung erreicht hat. Da im Stand der Technik regelmäßig die an denselben Schienen der Führung geführten Führungsvorrichtungen (insbesondere Rollenführungsvorrichtungen) von Fahrkorb und Kabelwagen kollidieren würden, kann die erfindungsgemäße Lösung insbesondere durch eine geeignete Anordnung und Ausbildung der Führungsvorrichtungen erreicht werden. Insbesondere besteht die Möglichkeit, die (untere) Führungsvorrichtung des Fahrkorbs so weit oberhalb des unteren Endes des Fahrkorbs vorzusehen, dass darunter noch Platz für die Führungsvorrichtung des Kabelwagens oder den gesamten Kabelwagen verbleibt. Die Führungsvorrichtung und/oder der Kabelwagen kann sich dann vorteilhaft (zumindest teilweise) zwischen dem Fahrkorb und der Führung befinden. Zusätzlich oder alternativ besteht die Möglichkeit, die Führungsvorrichtung des Kabelwagens zumindest teilweise an anderen Führungsschienen oder an anderen Seiten derselben Führungsschienen der Führung angreifen zu lassen als die Führungsvorrichtung des Fahrkorbs, wodurch ebenfalls eine Kollision der beiden Führungsvorrichtungen vermieden werden kann.The inventive solution for lowering the entry threshold in a generic elevator can be solved by a largely arbitrary construction, which prevents the car and the cable car would collide before the car has reached the desired lowest position on the guide. Since in the prior art regularly guided on the same rails of the guide guides (especially roller guide devices) would collide car and cable cars, the solution according to the invention can be achieved in particular by a suitable arrangement and design of the guide devices. In particular, there is the possibility of the Provide (lower) guide device of the car so far above the lower end of the car that there is still room left for the guide device of the cable cart or the entire cable car. The guide device and / or the cable car can then be advantageous (at least partially) between the car and the guide. Additionally or alternatively, it is possible to at least partially engage the guide device of the cable cart on other guide rails or on other sides of the same guide rails of the guide as the guide device of the car, which also a collision of the two guide devices can be avoided.

In einer bevorzugten Ausgestaltung des erfindungsgemäßen Aufzugs kann vorgesehen sein, dass die Führungsvorrichtung des Kabelwagens (mindestens) einen U-förmigen Tragrahmen mit zwei Parallelträgern und einem die Parallelträger verbindenden Querträger aufweist, wobei an den Parallelträgern Führungsrollen vorgesehen sind, die an der Führung abrollen.In a preferred embodiment of the elevator according to the invention can be provided that the guide device of the cable cart (at least) has a U-shaped support frame with two parallel carriers and a cross member connecting the parallel carrier, wherein guide rollers are provided on the parallel carriers, which roll on the guide.

Dabei kann weiterhin bevorzugt zumindest einer der Parallelträger (mindestens) einen sich in Längsrichtung der Führung erstreckenden Vertikalträger mit (mindestens) einer Führungsrolle aufweisen. Dadurch kann ein relativ großer Abstand (in Längsrichtung der Führung) zwischen der Führungsrolle des Vertikalträgers und den anderen Führungsrollen der Führungsvorrichtung und daher eine gute Kippstabilität des Kabelwagens realisiert werden, insbesondere wenn die Führungsrolle des Vertikalträgers - im Vergleich zu den anderen Führungsrollen der Führungsvorrichtung - an einer anderen Führungsschiene oder an einer anderen Seite derselben Führungsschiene angreift.In this case, furthermore, at least one of the parallel supports may (at least) preferably have a vertical carrier extending in the longitudinal direction of the guide with (at least) one guide roller. This allows a relatively large distance (in the longitudinal direction of the guide) between the guide roller of the vertical support and the other guide rollers of the guide device and therefore a good tilt stability of the cable cart can be realized, especially if the guide roller of the vertical support - compared to the other guide rollers of the guide device - to engages another guide rail or on another side of the same guide rail.

In einer weiterhin bevorzugten Ausgestaltung des erfindungsgemäßen Aufzugs kann zudem vorgesehen sein, dass die Führungsvorrichtung des Kabelwagens einen Träger mit einem Zahnrad, das mit einer Zahnstange der Führung kämmt, aufweist. Zusätzlich kann vorgesehen sein, dass der Träger ebenfalls eine Führungsrolle aufweist, die an einer der Verzahnung gegenüber liegenden Seite der Zahnstange angreift. Durch den sich vorzugsweise in Längsrichtung der Führung erstreckenden Träger mit Zahnrad und Führungsrolle kann die Kippstabilität des Kabelwagens weiter erhöht werden. Bei dem Träger kann es sich selbstverständlich auch um den Vertikalträger der zuvor beschriebenen bevorzugten Ausführungsform handeln. Dabei kann auch vorgesehen sein, dass das Zahnrad die Funktion der Führungsrolle bei der vorbeschriebenen Ausführungsform übernimmt.In a further preferred embodiment of the elevator according to the invention may also be provided that the guide device of the cable trolley has a carrier with a gear which meshes with a rack of the guide. In addition, it can be provided that the carrier also has a guide roller which engages on one of the toothing opposite side of the rack. By extending preferably in the longitudinal direction of the guide carrier with gear and guide roller, the tipping stability of the cable cart can be further increased. The carrier may of course also be the Vertical support of the previously described preferred embodiment act. It can also be provided that the gear assumes the function of the guide roller in the above-described embodiment.

Der in den Zeichnungen dargestellte Aufzug umfasst eine Bodenstation 1, von der aus sich eine Führung 2 in senkrechter Richtung erstreckt. Die Führung 2 besteht aus einzelnen Führungssegmenten, die miteinander verbunden sind. Die Führungssegmente sind als Fachwerk aus miteinander verbundenen Streben aufgebaut, wobei vier (alternativ: zwei) parallel verlaufende Vertikalstreben 3 vorgesehen sind, die über eine Vielzahl von Querstreben miteinander verbunden sind. Der Querschnitt der Führung 2 ist viereckig, wobei die Vertikalstreben einen kreisförmigen Querschnitt aufweisen.The elevator shown in the drawings comprises a ground station 1, from which a guide 2 extends in the vertical direction. The guide 2 consists of individual guide segments which are interconnected. The guide segments are constructed as a truss of interconnected struts, with four (alternatively: two) parallel vertical struts 3 are provided, which are interconnected via a plurality of transverse struts. The cross section of the guide 2 is quadrangular, wherein the vertical struts have a circular cross-section.

An einer der Seiten der Führung 2 ist ein Fahrkorb 4 verfahrbar geführt. Hierzu sind mehrere Rollenführungen 5 mit Führungsrollen vorgesehen, die an zwei benachbarten, als Führungsschienen dienenden Vertikalstreben 3 abrollen. Dabei sind insgesamt vier Rollenführungen 5 in der Nähe des oberen Endes (nicht dargestellt) und vier weitere Rollenführungen in der Nähe des unteren Endes des Fahrkorbs 4 an diesem befestigt.On one of the sides of the guide 2, a car 4 is movably guided. These are a plurality of roller guides 5 provided with guide rollers, which roll on two adjacent, serving as guide rails vertical struts 3. In this case, a total of four roller guides 5 in the vicinity of the upper end (not shown) and four other roller guides in the vicinity of the lower end of the car 4 attached thereto.

Der Fahrkorb 4 umfasst weiterhin einen Fahrantrieb (nicht dargestellt) mit einem oder mehreren Elektromotoren, deren Antriebsritzel in eine Zahnstange 7 eingreifen, die parallel zu den Vertikalstreben 3 verläuft. Durch einen Betrieb der Elektromotoren kann der Fahrkorb 4 entlang der Führung 2 verfahren werden.The car 4 further comprises a travel drive (not shown) with one or more electric motors whose drive pinion engage in a rack 7, which runs parallel to the vertical struts 3. By operation of the electric motors, the car 4 can be moved along the guide 2.

Die Elektromotoren werden über ein Kabel 8 mit elektrischer Energie versorgt. Das Kabel 8 erstreckt sich zwischen dem Fahrkorb 4 und einer Umlenkeinrichtung 9 eines Kabelwagens 10 sowie zwischen der Umlenkeinrichtung 9 und einer Fixierung 19, die etwas oberhalb der halben (Gesamt-)Höhe der Führung 2 an dieser fixiert ist. An der Fixierung 19 ist das Kabel 8 einer entlang der Führung 2 zur Bodenstation 1 geführten elektrischen Leitung verbunden, die dort an eine elektrische Energiequelle angeschlossen ist. Der Abstand zwischen der Fixierung 19 und der Bodenstation 1 ist etwas größer als der Abstand zwischen der Fixierung 19 und der Position eines auf Höhe der Elektromotoren an dem Fahrkorb 4 befestigten Kabelhalters 20, wenn sich der Fahrkorb 4 in seiner höchsten Halteposition befindet. Dadurch wird sichergestellt, dass der Fahrkorb 4 trotz der Befestigung des Kabels 8 an der Fixierung 19 alle vorgesehenen Haltepositionen anfahren kann. Dabei ist gewährleistet, dass das Kabel 8 immer in einer Schlaufe über die Umlenkeinrichtung 9 des Kabelwagens 10 geführt ist, wodurch vermieden wird, dass das in der Schlaufe geführte Kabel 8 infolge der Bewegung des Fahrkorbs 4 und aufgrund von darauf einwirkenden Windkräften unkontrollierte Bewegungen ausführt. Die Umlenkeinrichtung 9 weist mindestens eine Umlenkrolle auf, über die das Kabel 8 geführt ist.The electric motors are powered by a cable 8 with electrical energy. The cable 8 extends between the car 4 and a deflection device 9 of a cable trolley 10 and between the deflection device 9 and a fixing 19, which is fixed slightly above half the (total) height of the guide 2 at this. At the fixing 19, the cable 8 is connected to a guided along the guide 2 to the ground station 1 electrical line, which is connected there to an electrical energy source. The distance between the fixation 19 and the ground station 1 is slightly greater than the distance between the fixation 19 and the position of a fixed to the height of the electric motors on the car 4 cable holder 20 when the car 4 is in its highest holding position. This ensures that the car 4, despite the attachment of the cable 8 to the fixation 19 can approach all the intended holding positions. It is ensured that the cable 8 is always guided in a loop on the deflection device 9 of the cable cart 10, thereby avoiding that guided in the loop cable 8 due to the movement of the car 4 and due to acting thereon wind forces uncontrolled movements. The deflection device 9 has at least one deflection roller over which the cable 8 is guided.

Der Kabelwagen 10 weist neben der Umlenkeinrichtung 9 noch eine Führungsvorrichtung 11 auf, über die die Umlenkeinrichtung 9 an der Führung 2 geführt ist. Bei einer Bewegung des Fahrkorbs 4 bewegt sich der Kabelwagen 10 in derselben Richtung, jedoch - aufgrund der einfachen Umlenkung - mit nur der halben Geschwindigkeit.The cable cart 10 has, in addition to the deflection device 9, a guide device 11, via which the deflection device 9 is guided on the guide 2. During a movement of the car 4, the cable carriage 10 moves in the same direction, but - due to the simple deflection - with only half the speed.

In der Fig. 1 ist der Fahrkorb 4 in einer Position oberhalb der Bodenstation 1 gezeigt. Der Kabelwagen 10 befindet sich dabei unterhalb des Fahrkorbs 4.In the Fig. 1 the car 4 is shown in a position above the ground station 1. The cable cart 10 is located below the car. 4

In der Fig. 2 ist der Fahrkorb 4 in seiner Halteposition in der Bodenstation dargestellt. Erfindungsgemäß befindet sich der Kabelwagen 10 dort nicht mehr unterhalb des Fahrkorbs 4. Vielmehr liegen die unteren Enden von Fahrkorb 4 und Kabelwagen 10 im Wesentlichen auf derselben Höhe. Dabei befindet sich die Führungsvorrichtung 11 des Kabelwagens 10 zu einem Großteil zwischen der Führung 2 und dem Fahrkorb 4, während die Umlenkeinrichtung 9 seitlich der Führung 2 angeordnet ist. Dies ermöglicht, die Halteposition des Fahrkorbs 4 in der Bodenstation 1 besonders nah an dem Boden vorzusehen.In the Fig. 2 the car 4 is shown in its stop position in the ground station. According to the cable car 10 is there no longer below the car 4. Rather, the lower ends of the car 4 and cable cars 10 are essentially at the same height. In this case, the guide device 11 of the cable cart 10 is located for the most part between the guide 2 and the car 4, while the deflecting device 9 is arranged laterally of the guide 2. This makes it possible to provide the holding position of the car 4 in the ground station 1 particularly close to the ground.

Um die Führungsvorrichtung 11 des Kabelwagens 10 in den Zwischenraum zwischen dem Fahrkorb 4 und der Führung 2 verfahren zu können, sind die vier (unteren) Rollenführungen 5 des Fahrkorbs 4 beabstandet von dem unteren Ende des Fahrkorbs 4 angeordnet. Zudem ist die Führungsvorrichtung 11 des Kabelwagens 10 relativ flach ausgebildet.In order to be able to move the guide device 11 of the cable trolley 10 into the intermediate space between the car 4 and the guide 2, the four (lower) roller guides 5 of the car 4 are arranged at a distance from the lower end of the car 4. In addition, the guide device 11 of the cable cart 10 is formed relatively flat.

Diese umfasst einen U-förmigen Tragrahmen mit zwei Paralielträgern 12 und einem die zwei Parallelträger 12 verbindenden Querträger 13. An dem einen Parallelträger 12 ist die Umlenkeinrichtung 9 befestigt. An diesem Parallelträger 12 sind zudem zwei Führungsrollen 6 drehbar gelagert. An dem zweiten Parallelträger 12 ist eine weitere Führungsrolle 6 drehbar gelagert. Zudem ist an dessen freien Ende ein erster Vertikalträger 14 befestigt, der sich parallel zu der Führung 2 nach oben erstreckt und an dem freien Ende eine vierte Führungsrolle 6 umfasst. Durch den ersten Vertikalträger 14 ergibt sich ein recht großer Abstand zwischen den zwei Führungsrollen 6 dieses Parallelträgers 12, wodurch ein relativ kippstabiles Führen des Kabelwagens 10 an der Führung 2 realisiert wird.This comprises a U-shaped support frame with two Paralielträgern 12 and the two parallel beams 12 connecting cross member 13. At a parallel support 12, the deflection device 9 is attached. At this parallel support 12 also two guide rollers 6 are rotatably mounted. At the second parallel support 12, a further guide roller 6 is rotatably mounted. In addition, at the free end, a first vertical support 14 is fixed, which extends parallel to the guide 2 upwards and at the free end comprises a fourth guide roller 6. By the first vertical support 14 results in a fairly large distance between the two guide rollers 6 of this parallel support 12, whereby a relatively stable tilting of the cable trolley 10 is realized on the guide 2.

Die vier, jeweils eine ebene Lauffläche aufweisenden Führungsrollen 6 der Parallelträger 12 rollen an denselben Vertikalstreben 3 der Führung 2 ab wie Führungsrollen (mit konkaver Lauffläche) der Rollenführungen 5 des Fahrkorbs 4, wobei die zwei jeweils einer Vertikalstrebe 3 zugeordneten Führungsrollen 6 des Kabelwagens 10 an sich gegenüberliegenden Seiten der Vertikalstrebe 3 abrollen und somit um 180° versetzt (bezüglich der Längsachse der dazugehörigen Vertikalstrebe 3) angeordnet sind. Dagegen rollen die Rollenführungen 5 des Fahrkorbs 4 an angrenzenden Seiten ab; diese sind somit um 90° versetzt (bezüglich der Längsachse der dazugehörigen Vertikalstrebe 3) angeordnet.The four, each having a flat tread guide rollers 6 of the parallel carrier 12 roll on the same vertical struts 3 of the guide 2 as guide rollers (with concave tread) of the roller guides 5 of the car 4, wherein the two each of a vertical strut 3 associated guide rollers 6 of the cable cart 10 Roll off opposite sides of the vertical strut 3 and thus offset by 180 ° (with respect to the longitudinal axis of the associated vertical strut 3) are arranged. On the other hand, the roller guides 5 of the car 4 roll on adjacent sides; these are thus offset by 90 ° (with respect to the longitudinal axis of the associated vertical strut 3).

An dem Querträger 13 des U-förmigen Tragrahmens ist ein zweiter Vertikalträger 16 befestigt. Dieser weist eine fünfte Führungsrolle 6 (ebenfalls mit ebener Lauffläche) sowie ein nicht angetriebenes Zahnrad 17 auf. Das Zahnrad 17 und die fünfte Führungsrolle 6 sind sowohl in Längsrichtung als auch in Querrichtung des zweiten Vertikalträgers 16 und damit auch der Führung 2 voneinander beabstandet angeordnet. Das Zahnrad 17 greift in die Zahnstange 7 der Führung 2 ein; die fünfte Führungsrolle 6 rollt auf der der Verzahnung gegenüber liegenden Seite der Zahnstange 7 ab. Durch die Führungsrolle 6 und das Zahnrad 17 des zweiten Vertikalträgers 16 wird wiederum ein kippstabiles Führen des Kabelwagens 10 an der Führung 2 realisiert.On the cross member 13 of the U-shaped support frame, a second vertical support 16 is attached. This has a fifth guide roller 6 (also with a flat running surface) and a non-driven gear 17. The gear 17 and the fifth guide roller 6 are arranged spaced apart both in the longitudinal direction and in the transverse direction of the second vertical support 16 and thus also the guide 2. The gear 17 engages the rack 7 of the guide 2; the fifth guide roller 6 rolls on the toothing opposite side of the rack 7 from. By the guide roller 6 and the gear 17 of the second vertical support 16, in turn, a tilt-stable guiding of the cable trolley 10 is realized on the guide 2.

Die Umlenkeinrichtung 9 ist mittels eines Anschlussflansches 18 mit dem U-förmigen Tragrahmen verbunden. Ein solcher Anschlussflansch 18 ist beidseitig des Tragrahmens vorgesehen, so dass die Umlenkeinrichtung entsprechend an beiden Seiten der Führung 2 angeordnet werden kann.The deflection device 9 is connected by means of a connecting flange 18 with the U-shaped support frame. Such a connection flange 18 is provided on both sides of the support frame, so that the deflection device can be arranged correspondingly on both sides of the guide 2.
