US Patent 7534083 Trailer operable in lowered and raised transport positions

A trailer includes a deck frame which can be supported in a lowered transport position in which the deck frame is spaced above the ground below a height of the wheels corresponding to a deck between configuration and a raised transport position in which the deck frame is spaced above the ground substantially at or above the height of the wheels corresponding to a deck over configuration. Consumers are thus only required to purchase a single trailer to meet the advantages of both trailer configurations. Load supports, independent of a lift mechanism of the trailer, are provided in addition to the linkage which controls displacement of the deck frame between the two positions to ensure that the deck frame is supported on the wheels in a manner so as to safely bear a load on the deck frame in both the lowered and raised positions.
