ABSTRACT:
A highly maneuverable utility vehicle has a relatively narrow chassis that includes a frame overlying a ground-engaging, direction controllable running gear which permits the vehicle to be driven through narrow passages such as through the gates of residential fences for the purpose of transporting transformers or the like to areas otherwise inaccessible to powered, load-bearing vehicles. An engine mounted at one end of the frame is operably connected with the track-type running gear and to a hoist mechanism for raising transformers for installation on power poles. Control means interconnecting the engine with the running gear and the hoist are adapted to selectively permit operation of either the running gear or the hoist mechanism.
