The thin-wall segment increases the inside trailer width within the same exterior dimensions. The 4000D-X thin-wall dry van accounted for approximately 45 percent of Utility’s dry van production in 2005, compared to about 5 percent in 2001, the company said.
The 4000D-X patented thin-wall design was engineered by forging an aluminum exterior skin with 80K steel interior panels separated by a core material. The 4000D-X 101 version provides 101.25 in. of inside width from lining to lining and 101 in. from wearband to wearband with 4,085 cubic feet of productivity, the company said.
The 4000D-X 100 version has deeper side posts with increased stiffness for bulge loads. Pre-painted white galvanized, high-strength interior lining panels provide a snag-free surface and 100 in. of inside width from wearband to wearband, the company said.
Utility also offers Alcoa Mill Products’ Translite exterior clear-coated, polished aluminum exterior side skin as an option on its 3000R reefer. It is lighter than stainless steel and resists peeling, corrosion and yellowing over time, the company said.
