ABSTRACT:
An apparatus is set forth to vary the wheel base configuration of a tractor-trailer apparatus, wherein the trailer is positionable upon a carriage mounted upon "C" shaped channel guide rails mounted on the framework of a tractor organization. The rails include a reciprocating carriage mounted thereon for engagingly latching and reciprocatingly positioning and securing the trailer relative to the tractor framework, whereupon retraction of the carriage simultaneously secures the trailer to the tractor and elevates the rear tractor wheels out of contact with an associated roadway. An electrical interlock is provided for indicating proper orientation of the trailer relative to the tractor.
