Abstract

A vehicle with its own traveling gear for towing an aircraft without draw tongue, has a U-shaped chassis frame recess that is open in the forward direction with a clamping and lifting device arranged therein for the nose wheels of an aircraft. The clamping and lifting device, which is oscillatingly suspended on the chassis frame 1, includes a pivoting and lifting ramp 8, as well as two parallel telescoping arms 10 arranged rigidly on the pivoting and lifting ramp 8, with telescoping cylinders 11 and with gripping arms 14, which can be pivoted in and whose nose wheel contact surfaces 18 are rigidly attached to the gripping arms 14, and of telescopingly adjustable holddown devices 12, 13, which are hinged to the support 7. FIG. 3 shows the clamping and lifting devices with the nose wheels 17 lifted.
