Terex Trucks has updated its TA300 articulated hauler with the introduction of a new and improved transmission. The 28-tonne (30-ton) vehicle incorporates the latest EP320 transmission from ZF as standard. This results in a 5% improvement in fuel efficiency, as well as enhanced performance and productivity, when compared to the previous model working in the same application, acccording to the manufacturer.

The new transmission comes with eight forward gears as well as four reverse gears, higher overall gear ratio spread, equal ratio steps between gears and optimized gear shifting with partial load shifts. The TA300 is also equipped with true independent front suspension as standard. In addition, the hauler’s maximum speed has increased to 55 km/h, up from 50 km/h. Other operational features include automatic shifting with manual over-ride, a hydraulic integral retarder and a hydraulic power-shift longitudinal differential lock.

Scott Pollock, product manager, Terex Trucks, said: “Developing and testing the new EP320 transmission for the TA300 was a collaborative effort between Terex Trucks and ZF. The new transmission has been calibrated specifically for the TA300 and rigorously tested for two years internally and by operators on real job sites, working in a variety of conditions."

The TA300 also now comes with long life transmission fluid, increasing the length of time between oil maintenance intervals from 1,000 to 4,000 hours. The updated TA300 will initially be available from August in the higher regulated emissions markets of Europe and North America.
