ABSTRACT:
An apparatus for moving parked aircraft with an omni-directional tractor via an aircraft lift dolly that is revolvably coupled thereto. The aircraft lift dolly may be removably coupled to the omni-directional tractor or may be integral to it. The aircraft lift dolly includes a lift mechanism having a lift carriage which is selectively elevated. The lift carriage includes a fixed forward chock and a rear chock that moves longitudinally and laterally with respect to the forward chock. The chocks are positioned about the aircraft nose gear without movement of the aircraft. Elevating the lift cradle elevates the chocks and the nose gear cradled therebetween.
