Circulating orJigback RopewaysIm Umlauf- oderPendelbetriebFunzionamento a motocontinuo o a va e vieniCableways can be divided into two general designs: circulatingand jig-back. With circulating design, the cable withthe moving function forms an endless loop, is supported bysheaves, and always moves in one direction. Several cabinsor cars travel evenly distributed along the cable, departing onone side and returning on the opposite side. With jig-backoperation, there are two cabins or cars, with one on oneside departing while the other on the other side returning atthe same time. There can also be the group aerial tramwaywhich, instead of two large cabins, has two groups of smallcabins attached to the cable directly behind one another.With circulating design, passengers enter and exitcontinuously, while with jig-back design, they enter and exitin groups. With the former, transport capacity depends uponthe size of the cabins or cars and the interval between them.With jig-back design, the size of the vehicles, the travelingspeed, and the length of the route are the determining factorsfor the maximum transport capacity. The greatest capacity ispossible with track-mounted cableways (highest speed) injig-back design (largest cars) over short distances (shortesttravel time).Seilbahnen gibt es für den Umlauf- und für den Pendelbetrieb.Beim Umlaufbetrieb bildet das Seil mit der bewegendenFunktion eine endlose, über große Scheiben gelenkteSchleife, die sich immer in dieselbe Richtung bewegt. Beidieser Betriebsart fahren viele Kabinen oder Wagen hintereinanderam Seil ›aufgefädelt‹ auf der einen Seite hin undauf der Gegenseite wieder zurück. Beim Pendelbetrieb gibtes zwei Kabinen oder Wagen, die immer auf derselben Seiteabwechselnd hin- und zurückfahren. Als Variante gibt esnoch die Gruppenpendelbahn, die anstelle von zwei großenKabinen zwei Gruppen von kleinen Kabinen hat, welchedirekt hintereinander am Seil befestigt sind.Die Fahrgastströme erfolgen beim Umlaufbetrieb kontinuierlich,beim Pendelbetrieb schubweise. Die Beförderungsleistungbeim Umlaufbetrieb hängt von der Größe derKabinen oder Wagen und deren Folgezeit ab. Beim Pendelbetriebsind die Größe der Fahrzeuge, die Fahrgeschwindigkeitund die Streckenlänge die maßgebenden Faktoren für dieerreichbare Beförderungsleistung. Maximale Beförderungsleistungensind mit Schienenseilbahnen (höchste Geschwindigkeit)im Pendelbetrieb (größte Wagen) auf kurzenStrecken (kürzeste Fahrzeit) erreichbar.Esistono impianti a fune sia a moto continuo sia a va e vieni.Nel moto continuo la fune in movimento, guidata da grossepulegge, forma un anello chiuso, che si muove sempre nellastessa direzione. In questo tipo di funzionamento le numerosecabine o vagoni, ‹ allineati › uno dietro l’altro sulla fune,si muovono su un lato in una direzione e sull’altro in quellacontraria. Nel funzionamento a va e vieni ci sono solo duecabine o vagoni, che alternativamente si muovono, sempresullo stesso lato, in su o in giù. Una variante è costituita dallefunivie a grappolo, dove le due grosse cabine sono sostituiteda due gruppi di cabine più piccole fissate alla fune unadietro l’altra.Negli impianti a funzionamento continuo i flussi dipersone sono costanti, mentre in quelli a va e vieni sonointermittenti. La capacità di trasporto dipende, nel primocaso, dalla capienza delle cabine o dei vagoni e dalla loroequidistanza. Nel secondo caso sono invece la grandezzadelle cabine, la velocità di viaggio e la lunghezza del tragittoa determinare la capacità di trasporto. Le capacità maggiorisi hanno nel caso di impianti su rotaia (massima velocità) afunzionamento a va e vieni (vagoni più grandi) che si muovonosu tragitti brevi (minor tempo di percorrenza).Above left: the schematic representation of a jig-backcableway. Actually, the jig-back sections are for the most parton a single track with a passing area in the center. Opposite:examples of a track-mounted cableway in circulating operation(Perugia) or in jig-back operation (Detroit).32Links oben die schematische Darstellung einer Pendelbahn.Tatsächlich werden Pendelstrecken auf der Schiene meisteingleisig und mit einer Ausweichstelle in der Mitte konzipiert.– Auf der rechten Seite Beispiele für eine Schienenseilbahn imUmlaufbetrieb (Perugia) bzw. im Pendelbetrieb (Detroit).In alto a sinistra la rappresentazione schematica di un impiantoa va e vieni. In realtà gli impianti a va e vieni su rotaia hannoquasi sempre uno scambio nel mezzo. – Nella pagina di destraabbiamo un esempio di un impianto su rotaia a movimentocontinuo (Perugia) e uno con movimento a va e vieni (Detroit).
