The seemingly contradictory demands of lighter weight and durability continue to define dry van trailer design and development in North America. Yet trailer manufacturers, through careful research and testing, have optimized their dry vans for tough weight-friendly service by using the latest in composite side panels and flooring, which has the useful side effect of optimizing interior van width and length and providing easier loading and unloading. These new composite materials are combined with the latest developments in high-strength aluminum and galvanized steel.
Instead of simply over-building trailers, designers have taken a fresh look at overall dry van design with an eye toward strengthening high-stress areas while reducing component weight in areas that encounter heavy torsional loads or lateral g-forces.
Perhaps the most visible evolution of the current dry van trailer design is the increasing use of aerodynamic skirts, wings and air dams to reduce overall unit drag and boost tractor-trailer fuel economy. This technology is still in its infancy, but if current fuel prices are any indication, it’s one we’ll be seeing more of in the future.
