Abstract
A shallow nose platform trailer provides improved load carrying capability due to its reduced platform height and thus increased volume capability. The trailer includes a pair of parallel, longitudinal main I-beams and a pair of channel beam side rails defining a height of about three and one-half inches (89 mm) at the forward portion of the trailer adjacent the kingpin. The webs and lower flanges of the I-beams curve downwardly to the rear and define a height of approximately twenty-five inches (635 mm) along the central and rear portion of the trailer. An apron plate extending between the forward portions of the I-beams carries and disperses the forces imposed on the trailer and longitudinal I-beams by the kingpin and fifth wheel. The apron plate defines a V-shaped notch at its rear. A plurality of transverse beams support a deck having an upper surface flush with the longitudinal I-beams and side rails.
