ABSTRACT:
A towing vehicle for towing a large aircraft that lifts, supports and moves the nose wheel of and consequently the aircraft itself, is provided. The towing vehicle has a frame which internally receives the aircraft's nose wheels. Forward and rear arcuate shaped nose wheel engaging members contact a substantial portion of the front and rear circumferential surfaces of the nose wheels. The forward nose wheel engaging members are pivotally attached to the front of the frame. The rear nose wheel engaging members are connected through hydraulic rams to the rear of the frame. When the hydraulic rams are extended, the nose wheels are lifted and rotated around the pivotal connection of the forward nose wheel engaging members and the frame thereby lifting and supporting the nose wheels off the ground. Movement of the towing vehicle then also moves the aircraft whose nose wheels are supported. The towing vehicle may either be a trailer type device which may be attached to an existing aircraft towing device or may be an integral unit which is able to move under its own power.
