Utility Trailer Manufacturing has introduced its next-generation D-X product, the 4000D-X Composite. A 2010-model composite-wall trailer, production will start in January 2009.

The newly-designed standard side wall is said to offer the same durability traits of a common plate trailer, with added performance characteristics like lower tare weight and load-securement versatility. The bonded construction of the composite side wall combines Utility’s patented sheet-and-post design with the foam technology benefits of its 3000R reefer — without compromising side wall strength or the 101-in. minimum wearband-to-wearband inside width. The polyurethane foam core of the new trailer structurally bonds the interior lining panels to the outside skin panels.

Premium features available standard, not as options or upgrades, with the 4000D-X® Composite™ include an interior that is fitted with fully-recessed vertical logistic posts on 24-in. centers (minimum) throughout the trailer. Utility’s 80,000 psi interior lining panels are “squeeze” riveted to the outer skin and side posts to form a patented Snag Free™ high-strength, durable wall system. Lining and side post structural fasteners are fully-recessed so they won’t be impacted by cargo or lift trucks.

The first line of defence for the trailer’s sidewall is the wearband. The lower portion of the interior panel of the 4000D-X® Composite™ includes a full-length, one piece 12” high 80,000 psi galvanized steel wearband for added impact protection, strength and stiffness.

Utility’s new 4000D-X® Composite™ also offers the industry’s strongest 27” deep integrated threshold plate. It is fully-welded to both the buckplate and the 24” deep side gussets. Extra floor support is built in, with two 5-1/8” deep steel channel crossmembers that are welded to the slider subframe and the bottom of the threshold plate.
