Description

BeschreibungDescription

Die Bewegung von Flugzeugen auf dem Boden erfolgt, zum Beispiel von der Abfertigung weg, oder bei Wartungs- und Überführungsfahrten, mit Flugzeugschleppern. An den Bugradstützen der Flugzeuge sind spezielle Adaptionsstellen zur Anbringung der Schleppstangen vorgesehen. Auf den Flughäfen werden eine Vielzahl von Schleppstangen benötigt, da die Adapter abhängig vom Flugzeugtyp unterschiedlich ausgeführt sind. Selbst verschiedene Flugzeugtypen mit gleichen Adaptern werden mit unterschiedlichen Schleppstangen bewegt,da zu jedem Flugzeugtyp entsprechende Scherstiftsicherungen eingesetzt sind. Dies führt zu einer aufwendigen Arbeitsweise, die Material- und Personalintensiv und zudem mit Gefahren verbunden ist. Die Erfindung löst das Problem durch eine hydraulisch zu bewegende, am Schleppfahrzeug (2) mitgeführte Schleppstange (1). Die hydraulische Absicherung der Zug- und Druckkräfte erübrigt die Scherstifte und einen Teil der deshalb notwendigen Schleppstangen. Weiter erforderliche Adapter (8), zur Verbindung am Flugzeug, werden im Schleppfahrzeug mitgeführt und mittels Schnellkupplung im Bedarfsfall ausgetauscht. Da die Bauweise der "mitgeführten Schleppstange" als Anbauelement keine spezielle Schlepperbauweise erfordert, kann auch an den verschiedensten Schlepperausführungen eine Nachrüstung erfolgen. Durch die verschiedenen Bewegungsmöglichkeiten der Schleppstange (1), ist eine exakte Anbindung des Flugzeugs (3), sowie die einfache Einmannbedienung möglich. Auf der Schleppstange angebrachte Bedientaster (9) ermöglichen zudem eine genaue Anpassung. Bei Leerfahrten wird die Schleppstange am Fahrzeug angelegt und verriegelt (Fig.2). In Fig.3 ist die ausgefahrene Schleppstange mit den verschiedenen Bewegungsmöglichkeiten dargestellt. Die Anbindung am Flugzeug zeigt Fig.l. Diese einfache Lösung läßt auch die teuren und hochtechnisierten stangenlose Schleppverfahren, die ein Anheben des Flugzeuges, sowie eine kritische Verformung und Beanspruchung des Bugrades erfordern, höchst fragwürdig erscheinen. (DE 3917255A1)Aircraft are moved on the ground, for example from the handling area or during maintenance and transfer journeys, using aircraft tugs. Special adapter points are provided on the nose wheel supports of the aircraft for attaching the tow bars. A large number of tow bars are required at airports, as the adapters are designed differently depending on the type of aircraft. Even different types of aircraft with the same adapters are moved using different tow bars, as each type of aircraft has its own shear pin locks. This leads to a complex working method that is material and personnel intensive, and also involves risks. The invention solves the problem by means of a hydraulically operated tow bar (1) carried on the towing vehicle (2). The hydraulic protection of the tensile and compressive forces eliminates the need for shear pins and some of the tow bars that are therefore required. Other adapters (8) required for connection to the aircraft are carried in the towing vehicle and can be exchanged using a quick coupling if necessary. Since the design of the "carried tow bar" as an attachment does not require a special tractor design, it can also be retrofitted to a wide variety of tractor models. The various movement options of the tow bar (1) enable precise connection to the aircraft (3) and simple one-man operation. Control buttons (9) attached to the tow bar also enable precise adjustment. When driving empty, the tow bar is attached to the vehicle and locked (Fig. 2). Fig. 3 shows the extended tow bar with the various movement options. Fig. 1 shows the connection to the aircraft. This simple solution also makes the expensive and highly technical rodless towing methods, which require lifting the aircraft and critical deformation and stress on the nose wheel, appear highly questionable.
