Abstract
An aircraft towing vehicle has a frame with a rearwardly open, U-shaped recess for receiving the nose wheel of an aircraft and a lifting and securing mechanism for raising the nose wheel off the ground and securing it to the towing vehicle in the raised position. The lifting and securing mechanism, in particular a hold-down mechanism and/or a lifter mechanism secure the nose wheel after it has been fully engaged by applying a wheel clamping force of a predetermined magnitude to the periphery of the wheel. The clamping force is selected to substantially prevent relative nose wheel movements while the aircraft is being towed.
