Dry Vans


CCJ’s annual three-part guide to trailer specifications begins this month with a look at select dry vans from selected leading suppliers.


Today’s dry vans are stronger than those of the past while often being lighter. Structural integrity has been improved due to more accurate methods in determining where stress loads are the highest, thanks primarily to better design tools that can analyze the properties of the various materials used in the construction process. By replacing heavier components with equally strong, lighter-weight materials and adding extra strength in areas that need beefing up, designers have been able to build significantly better trailers to carry specific loads without fatiguing certain design elements.

Manufacturers also have reduced trailer weight by employing lighter, higher-strength materials in practically every area of the trailer, including the use of composite floors, which also increase load capacity. Another trend is composite panels used as side, front and rear door materials, which allow maximum interior width and length, and a smooth snag-free interior. Thinwall designs continue to gain popularity because they provide added interior width and cube capacity, which means more freight per trailer and better margins for fleets. Many fleets also spec anti-snag roof bows because they help prevent damage to cargo as it’s being loaded.

As durability and maintenance have become major issues for fleets, trailer manufacturers have moved away from, or engineered alternatives to, traditional plywood liners.
Look for specs of selected refrigerated models in May and flatbeds in July.
