Unmanned, self-propelled tug for light aircraft

摘要

The dolly has a rotating arm (7) receiving a front wheel of a plane against a fixed stop by flat lateral guides. The arm has a drawbar flange held with bars by two tubes. A removable stop mounted on a rack blocks the wheel to tilt the arm and to handle the dolly. A manual pressure is applied on a control drawbar (5) to lift off the wheel, after releasing the arm by unblocking the drawbar.
