The same physics that apply to tractor fuel economy improvements can be applied to the trailer. The more aerodynamic the tractor is, the more critical it is for the trailer to play a complementary role in streamlining airflow.
Studies have shown that the fuel economy difference between a typical fleet van and a more aerodynamic trailer is 1 mile per gallon or more. So an owner-operator could add $10,000 or more to his bottom line in one year by using a trailer with strong aero features. That means the trailer would pay for itself long before it wears out.
The great news is we can build fuel-efficient trailers with products already on the market. I’ve been working with some companies to design and build the most fuel-efficient trailer possible.
We’re using SmartTruck’s UnderTray system, which is more durable and less susceptible to damage. It addresses many of the trailer’s aerodynamic problems, including the undercarriage, tandems, the top and sides of the trailer, and the low pressure created behind the trailer. We’re also working on designs to improve the aerodynamic efficiency at the front of the trailer.
The other key factors are rolling resistance and mechanical resistance. We designed the trailer with the most fuel-efficient, low rolling resistance tire possible. We’ve also incorporated liftable axles so that the only tires on the ground are those needed to carry the weight at any given time. We’re also using an automatic tire inflation and tire pressure monitoring system.
To reduce mechanical resistance, we are employing racing technology by using the MicroBlue polishing and coating process on all bearings, axles and any other component subject to friction. These improvements, along with many others, have shown fuel mileage increases as much as 1 mile per gallon or more over typical trailers.
You know how frustrating it is to pick up a trailer with brakes out of adjustment or malfunctioning completely. Putting the owner-operator in ownership of the trailer drastically reduces those problems, as well as the downtime that comes with them.
