Abstract: An adjustable height fifth wheel hitch is provided. The fifth wheel hitch comprises a pedestal and a fifth wheel hitch assembly. The fifth wheel hitch assembly includes journal bearings which pivotally connect with risers of the pedestal. The risers of the pedestal include a plurality of openings located at different levels. The height of the fifth wheel assembly in relation to the tractor may be adjusted by aligning openings in the journal bearings with co-level openings in the risers and inserting a mounting pin through such openings.

Abstract: A bracket assembly for an adjustable fifth wheel hitch is suitable for mounting to a slide rail assembly, which itself is mounted to parallel longitudinal truck frame members, where the slide rails have a generally t-shaped cross-section. The slide rail is comprised of a horizontal portion and a vertical portion, the vertical portion including a plurality of spaced-apart gaps. The bracket assembly comprises a bracket body with longitudinal disposed front and rear ends, with respect to the truck body, a longitudinal channel defined in the underside that extends from front and rear openings defined in the respective surfaces of the front and rear ends with a generally t-shaped cross-section to slidably receive said slide rail. The bracket body also has two spaced-apart transverse channels defined in the underside, perpendicular to the longitudinal channel. The transverse channels align with two of the space-apart gaps as the bracket body is slid along the slide rail.

Abstract: An integrated cross-member mount comprises an inter-frame mount seated within opposing longitudinal channels of parallel adjacent truck frame members and comprises a top surface within each lateral portion of which is defined a longitudinally-oriented row of spaced-apart, shaped apertures, and at least two substantially vertical flanges extending downward from the lateral periphery of the top surface that are dimensioned to be conforming to the inner surfaces of truck frame members. Also included is a sliding pedestal having lateral skids seated upon respective portions of rows of spaced-apart apertures and extending into vertical gaps between the top surface of the mount and the truck frame member. Each skid includes a plurality of spaced-apart, shaped skid apertures that can align with a corresponding plurality of shaped apertures within the top surface of the mount.
