  • Patent number: 5553989
    Abstract: A trailer for hauling vehicles includes a central frame with a pair of longitudinal tubular members and a plurality of transverse tubular cross-members interconnecting the longitudinal members to form an open frame. A pair of ladder frames are affixed along the longitudinal outward faces of the longitudinal members and project transversely therefrom in opposite directions. Each transverse ladder frame includes an outer rail extending parallel to the longitudinal members, and a plurality of rungs connecting the outer rails to the longitudinal members. A pair of tread plates are supposed on the ladder frames and extend from the forward to the rearward end of the frame, the tread plates spaced-apart a distance to support the wheels of a vehicle thereon. A wheel assembly is mounted on the frame to permit transport of the trailer, and a hitch is mounted on the forward end of the frame to permit connection to a pickup or other prime mover.
