TITLE TERMINAL TRACTOR A terminal tractor for maneuvering a trailer having a fifth wheel component in a confined area has front and rear wheeled sections pivotally connected via an intermediate section for steering the tractor by articulation of the front and intermediate sections relative to each other. The articulation pivot in combination with the fifth wheel pivot connection between the tractor and trailer allows the trailer to be parked by backing with relatively little longitudinal movement of the trailer required. The intermediate section is connected to the rear section by an oscillating connection for allowing the rear section to rotate with respect to the front and intermediate sections along a generally longitudinal axis to allow all of the tractor's wheels to maintain road contact while traveling on irregular road surfaces. The fifth wheel plate of the tractor may be selectively raised to lift the forward ground support of the trailer above the road surface to allow rapid repositioning of the trailers. |
