  • Towing apparatus
    Patent number: 6352130
    Abstract: A towing apparatus capable of moving aircraft and other workpieces about an airfield or other workspace. The present invention includes a first frame which is rotatable relative to a second frame about a common substantially vertical axis. A wheel assembly is positioned within the first frame and driven by a motor which is also mounted on the first frame. A gripper assembly for engaging the aircraft or other workpiece is attached to the second frame. In this manner, the present invention provides for a towing of aircraft or other workpieces along an axis which is proximate the axis of the wheel assembly. Additionally, it provides for a low center of gravity significantly enhancing the stability and maneuverability of the present invention in a towing attitude or a non-towing attitude.
