Trailer Focus: Dry Vans

user-gravatar

This month, CCJ launches a three-part guide to trailer specifications with a look at select dry vans from leading suppliers.

State-of-the-art engineering has made today’s dry vans stronger than those of the past. 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.

In addition, trailer weight has been reduced by utilizing 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.

Durability and maintenance also have become major issues for fleets; that’s why most trailer companies either have moved away from, or engineered alternatives to, traditional plywood liners.

In May, we’ll highlight refrigerated models, and in July, we’ll take a closer look at flatbeds.
