  • Patent number: 6450756
    Abstract: An aircraft towbar apparatus comprises a pair of tubular members having proximal ends coupled to a hitch assembly for attachment to a towing vehicle. Each tubular member includes a gripping member at a distal end for gripping an aircraft wheel assembly. The apparatus includes a wheel assembly intermediate proximal and distal ends which serves as a fulcrum for vertical positioning of the gripping members relative to an aircraft wheel assembly. A support handle extends from the distal end of one tubular member to enable a user to vertically position the gripping members. A scissor jack is connected to the tubular members and extends therebetween at a position spaced from the distal ends. An elongate handle bar is coupled to the scissor jack and extends to a crank handle adjacent the hitch assembly such that a user may rotatably actuate the scissor jack to vary the spacing between the tubular members.
