ABSTRACT:
An aircraft towing vehicle is equipped with an aircraft nose wheel lifting and securing mechanism. The nose wheel is received in a U-shaped recess of the vehicle chassis, the lifting mechanism being constructed to grip the wheel from behind and underneath and to then push it up a ramp. The tilt angle of the lifting mechanism as it advances towards the wheel is controlled by a steering linkage such that the lower, freely movable segment of the lifting mechanism is tilted farther forward and beneath the nose wheel at the beginning of the nose wheel engaging operation, while conversely, a rigid upper segment is tilted farther forward as the engaging operation continues to completion.
