ATDynamics debuts roll door TrailerTail design

Updated Feb 22, 2012

At the Technology and Maintenance Council Spring Meeting in Tampa, Fla., ATDynamics announced its new RollTail, a rear-mounted aerodynamic fairing designed for truck fleets that operate trailers with roll doors. Previous TrailerTail designs have been for swing-door trailers.

“Over half of the top 10 largest for-hire and private trucking operations in the United States depend on roll doors rather than swing doors,” said Andrew Smith, ATDynamics chief executive officer and founder. “In addition, the U.S. Postal Service requires its contract carriers to use roll door trailers for longhaul mail delivery. That’s why we look forward to working with leading roll door fleets, in addition to our existing swing-door trailer customers, to save the industry hundreds of millions of dollars annually in fuel costs.”

The new RollTail is a spring-actuated fairing that ATDynamics says can be installed by two technicians in as little as 45 minutes. The unit requires no driver interaction when backing into a loading dock, as the unit retracts and deploys automatically when the vehicle pulls away.

Smith said the RollTail will improve tractor-trailer fuel economy by 4 to 5 percent and has been validated by SAE Type II fuel economy testing. The fairing weighs about 160 pounds and will retail for $1,599.00.
