ABSTRACT:
A tractor and a trailer are designed for operation in tight spaces, The tractor's wheels can each be powered and steered under user control. Preferably the frame is less than nine by nine feet, can support at least ten thousand pounds, can change direction in place, and can be operated by remote control. In some embodiments the trailer's hitch connector is a fifth wheel. In others it is mounted at the end of a powered, telescoping, horizontally swinging arm. The tractor can include connections for supplying hydraulic or electric power to one or more external devices, such as ones which can be mounted on the end of its rotable arm, instead of the hitch connector. The arm can have a double-jointed, hydraulically powered extension for extra flexibility. The tractor's engine can be non-polluting so it can be used inside. The wheel of the trailer can each be powered and steered, so the tractor-trailer combination is highly maneuverable. The trailer can receive power for its wheels from the tractor. The trailer can be a boat trailer having powered arms for supporting a boat hull. The boat trailer can be one which has no fixed cross members in its rear portion, so it can back around the keel of a boat. The trailer can have a retractable wheel to support its front when it is disconnected from the tractor.
