SmartTruck, a new manufacturer of aerodynamic products for the trucking industry, has introduced the second generation of its UT-6 Trailer UnderTray System. SmartTruck said it has begun production of the more durable and versatile redesigned version, which still delivers a fuel efficiency gain of more than 10%, according to test results.
“The pace at which the industry is embracing the Trailer UnderTray System encourages us to further develop the product and bring additional enhancements to the industry,” said Mitch Greenberg, president, SmartTruck. “This redesigned system provides greater durability and is much more adaptable to fit the wide range of trailer models on the road today, while still delivering outstanding fuel efficiency.”
The new UT-6 UnderTray System includes redesigned components that are higher off the ground and allow the sled to be independent of the suspension system. According to the company, the redesigned system also reduces the size of the rear diffuser, allowing the suspension system to travel to the full rearward position. The redesigned components, along with a more universal hardware package, combine for easier installation on a wide range of trailer models, cutting installation time to less than two shop hours per system, SmarTruck said, adding that along with increased fuel efficiency, a secondary benefit of the UnderTray System is cooler operating temperatures around the brake, tire and wheel assemblies due to increased airflow under the trailer.
Fleets currently using the SmartTruck UnderTray System include Con-way, Hirschbach Motor Lines and Turk Enterprises. Other fleets evaluating the SmartTruck system include Schneider, U.S. Xpress and Fremont Contract Carriers.
“We’re excited about getting our trailer units outfitted with the new version of the UnderTray System,” said Jim Coffren, vice president, Hirschbach Motor Lines. “We like this new way of thinking about trailer aerodynamics, encouraging and using airflow under and around the trailer – not blocking it. We expect great results from the system.”
