  • Patent number: 5302075
    Abstract: An aircraft tug assembly is provided for moving an aircraft on the ground. The tug assembly includes a self-propelled chassis responsive to operator control. A cradle assembly is pivotally attached to a front portion of the chassis. The cradle assembly has an adjustable nosewheel receiving apparatus comprising two lateral arms adjustably engaged with a rear gate to define a nosewheel receiving corral therebetween, with the corral sizable to accommodate varying sized aircraft nosewheels. The chassis has a winch, or alternatively a telescoping arm, for pulling an aircraft nosewheel onto the cradle assembly and into the corral. An optional front gate may be used to enclose the nosewheel within the corral. Hydraulic actuators lift the cradle assembly with the nosewheel thereon so the tug assembly may move the aircraft without starting the aircraft engine.
