摘要： 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.

摘要： 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.
摘要翻译：一架拖拉机没有拉扯舌头，底盘通过一个轴向平行的弯曲轴分开。用于飞机的前起落架（前轮27）的拾取装置布置在由提升摇杆形成的底盘的叉形凹部内。该拾取装置包括升降平台，摆杆连杆，具有夹持臂的伸缩臂，推出拉杆，横杆，纵向摆动臂和摆针。摆杆连接杆，具有伸缩臂的升降平台，包括推出式连杆和纵向摆动臂，通过联接构件连接到底盘后部的提升摇杆。摆杆系杆具有摆式安装，提升平台和摆杆系杆的摆动运动与可枢转安装的升降平台相结合。由于高度可调的伸缩臂可枢转地连接到升降平台和摆杆连杆上，所以它们能够参与摆动运动。
