ABSTRACT:
The aircraft tractor arrangement maintains a uniform degree of reliability with which the nose wheel landing gear, which is standing on a lifting platform that is arranged on the front part and extends into a recess (26), is held down on the surface of the lifting platform which supports the nose wheel landing gear at different nose wheel diameters.
Each telescoping rod (30) is hinged (40, 44, 46) to the front part (10.1) directly in the front. A connecting hydraulic cylinder (42) is provided in the rear. The hydraulic cylinder (46) for longitudinal adjustment, and also the hydraulic cylinder (36) for moving the holder (34) on the fixed part (30.1) of the telescoping rod (30) associated with it are arranged ridgedly.
This arrangement allows an adjustability in height of the two rear tow arms and at the same time of the front holders, which can come into contact with the two desired zones of the wheel circumference, regardless of the nose wheel diameter. The distance between the arms and the holders is adjustable.
