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. A pair of inner rails are mounted parallel to the ladder frame outer rails, and located inwardly of the longitudinal members. The inner rails and ladder frame outer rails project upwardly beyond the upper surfaces of the rungs of the ladder frames and the upper surfaces of the longitudinal members. The tread plates are preferably journaled between the inner and outer rails and supported on the longitudinal members and rungs. A pair of ramps are provided which are removably connected to the rearward end of the trailer to provide access to the trailer tread plates. A ramp receiving pocket is formed on the trailer to permit storage of the ramps on the trailer.
