ABSTRACT:
A trailer, as part of a tractor-trailer combination, wherein the trailer is an enclosed van having a collapsible goose neck which connects the trailer to the tractor and provides a ramp into the interior of the van, which is a substantially enclosed structure providing protection for its contents. The goose-neck has a raised and a lowered position and comprises a pair of opposing side plates, a platform, and a tongue. A pair of hydraulic cylinders are provided to lift the van, thus enabling the van to be unhitched from the tractor. A pair of pneumatic cylinders retain the goose neck in its raised position, until a fork lift engages the tongue. After engagement the cylinders are retracted and the goose neck is lowered and once doors carried by the van are opened, access into the interior of the van is available. In the lowered position, the supporting blocks support the trailer with the platform extending approximately parallel to the floor of the van. The side plates support the platform, enabling the tongue to descend from the platform, thus providing a gentle ramp for a forklift to enter the van. In the present embodiment, the trailer optimizes the use of interior space within the van according to external dimensional restrictions as applied by the trucking industry.
