ABSTRACT:
In an aircraft maneuvering tractor (1) for the maneuvering of aircraft (2) without the aid of a tractor drawbar, wherein the chassis of the tractor has a bifurcated receiving space which is provided between the wheels (3) of a wheel axle (4) and in which a retractable and extractable pulling-in device is arranged, by which the nose wheel (9) of an aircraft (2) can be gripped and pulled onto a shovel (10) which is movable relative to the chassis and which has a substantially horizontal bearing surface (11) onto which the nose wheel (9) is to be laid and a substantially vertical stop surface (12) against which the nose wheel (9) will abut, together with at least one hold down member (13) which is disposed over the shovel (10) and which is adapted to be laid from above against the nose wheel (9) and to be impinged by a holding down force. The hold down member (13) is formed substantially in the shape of an angle or an arc so that the inner side (15) of such angle or arc is turned towards the nose wheel (9). The hold down member (13) has a free end (16) and end (17). End (17) is mounted for pivotal movement about a swivel axle (19) which is substantially parallel to the axle (18) of the nose wheel (9) and which is mounted on said tractor (1), and in the neutral position the vertical distance (a) of angle (14) from the bearing surface (11) of the shovel is less than the respective diameter (D) of the nose wheel.
