Terex Trucks updated its TA300 articulated hauler with an improved transmission.

The 30-ton hauler now incorporates the latest EP320 transmission from ZF as standard. According to Terex Trucks, this results in a 5 percent improvement in fuel efficiency, as well as enhanced performance and productivity, when compared to the previous model working in the same application.

“Developing and testing the new EP320 transmission for the TA300 was a collaborative effort between Terex Trucks and ZF,” says Scott Pollock, product manager at Terex Trucks. “The new transmission has been calibrated specifically for the TA300 and rigorously tested for two years internally and by operators on real jobsites, working in a variety of conditions. Operators have had nothing but praise for the upgraded machine.”

The updated transmission comes with eight forward gears and four reverse gears, a higher overall gear ratio spread, equal ratio steps between gears and optimized gear shifting with partial load shifts. All of this helps to ensure smoother gear shifting and higher levels of operator comfort, the company says.

The TA300 is also equipped with an independent front suspension as standard, further enhancing operator comfort and enabling traction control and maximum productivity in challenging conditions, the company says.

In addition, the hauler’s maximum speed increases to 34 mph, up from 31 mph. As a result, customers can achieve faster cycle times and a lower cost per ton.
