ABSTRACT:
A double lead-pup trailer assembly for container transport has swivel bunks enabling the container to be carried on the articulated trailers. The rear swivel bunk slides rotatably within a slot extending to the rear of the pup trailer allowing the container to be directly unloaded. The coupling means between the trailers is adjustable between a highway articulated driving relationship, and a backing up aligned relationship. One advantage is the gross vehicle weight and payload are improved. Another advantage is that the container more closely tracks the tractor and trailer wheels on turns, thus providing more manoeuvrability and safety.
