Abstract

An aircraft tug without draw tongue, with a chassis divided by means of an axially parallel buckling axle. The pickup device for the nose landing gear (nose wheels 27) of an aircraft is arranged within the fork-shaped recess of the chassis, which is formed by the lifting rockers. This pickup device includes a lifting platform, a pendulum tie-bar, telescopic arms with gripping arms, a push-out tie-bar, a crossbar, longitudinal swinging arms, and a pendulum pin. The pendulum tie-bar, the lifting platform with the telescopic arms, including the push-out tie-bar and the longitudinal swinging arms, are connected to the lifting rockers of the chassis rear part via coupling members. The pendulum tie-bar has a pendular mounting, and pendular movement of the lifting platform and of the pendulum tie-bar is guaranteed in conjunction with the pivotably mounted lifting platform. Since the height-adjustable telescopic arms are pivotably linked to the lifting platform and to the pendulum tie-bar, they are able to participate in the pendular movement.
