COMMERCIAL CARRIER JOURNAL | APRIL 2015 65 M ost of today's dry vans are lighter and stronger than those of the past. By replacing heavier components with equally strong but 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. Structural integrity has been improved due to more ac- curate 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. Manufacturers also have reduced trailer weight by using composite floors, which also increases load capacity. Com- posite panels used as side, front and rear door materials allow maximum interior width and length, as well as a smooth snag-free interior. Thinwall designs also provide added inte- rior 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. And as du- rability 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 flatbeds in July and refrigerated models in October. TRAILER FOCUS LOOK FOR SPECS OF SELECTED FLATBEDS IN JULY AND REFRIGERATED MODELS IN OCTOBER.
