US 6,733,219 B1 · Trailer structures

Abstract

Trailer structure having a tilt limiting loading ramp and an improved structural side member forming an adjustable axle mount and having a load tie down track is described. The trailer has a load supporting bed and utilizes a load tie down system having tie down tracks at each side and one or more additional tie down tracks at selected locations on the load supporting bed. One or more tie down devices are selectively positionable in each tie down track and are used to restrain various loads including various wheel supported loads. To accommodate a low trailer profile an improved tongue adaptor is provided. A fender mount structure to cooperate with the improved structural side member is also described. Improved loading ramp structures, including a tilt-bed loading ramp and a tilt limiting structure for limiting the angle of bed tilt for use on a tilt-bed trailer are shown. A rack structure to mount to the load tie down tracks in the structural side members is shown.

Dependent claims

A tilt-bed trailer comprising:

a bed supporting frame including at least two oppositely disposed side structural members;
at least two axle mounted wheels coupled to said bed supporting frame;
a bed having a load supporting surface, a predetermined bed length dimension and a predetermined bed width dimension, said bed supported on said bed supporting frame;
an elongated tongue structure rotatably coupled to said bed supporting frame;
a tongue retention and release mechanism to selectively retain said bed supporting frame in contact with said elongated tongue structure or to release said bed supporting frame from said elongated tongue structure to allow said bed supporting frame to tilt;
a tilt limiting loading ramp rotatably coupled to said bed supporting frame, said tilt limiting loading ramp having a predetermined ramp length and including a tilt limiting structure to engage a loading surface to limit the slope of tilt of said bed such that said load supporting surface of said bed and said tilt limiting loading ramp are substantially aligned when loading or unloading a wheel supported load.
