Terex Trucks’ new TA300 articulated hauler is now equipped with a new transmission, which provides a boost in ground speed and a reduction in fuel consumption.

The 28-tonne hauler now incorporates the latest EP320 transmission from ZF as standard. This results in a 5 per cent improvement in fuel efficiency, as well as enhanced performance and productivity, when compared to the previous model working in the same application.

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 shifting with partial load shifts. This helps ensure smoother gear shifting, equalling higher levels of operator comfort, according to the company.

The TA300 is also equipped with true independent front suspension as standard, further enhancing operator comfort and enabling improved traction control and maximum productivity in the most challenging of conditions.

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.

Together, this helps ensure safe and productive operation, as well as reduced fuel and diesel exhaust fluid (DEF) consumption on jobsites.

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.

“Introducing the new transmission to the TA300 articulated hauler continues Terex Trucks’ commitment to install product performance and productivity improvements that lead to lower operational costs for our customers,” said Scott Pollock, product manager at Terex Trucks.

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 jobsites, working in a variety of conditions,” Pollock said.

“Operators have had nothing but praise for the upgraded machine. Among some of the most commonly cited benefits are the improved fuel efficiency and performance, as well as the smoother gear shift quality.”

The hauler’s fuel-efficient Scania DC9 engine meets the requirements of Tier 4 Final emissions legislation without a diesel particulate filter (DPF).

Together with the new transmission, this means reduced fuel consumption and operational costs.

The machine has fully enclosed, oil-cooled, multi-disc brakes at all six wheels. These are supported by both the engine brake and the transmission retarder, giving the operator more control and increasing safety.

As well, the cab boasts pressurized capabilities and a high-performance HVAC system for high levels of operator comfort.

Ground level test points combined with a fully tilting cab and an electronically raised hood ensure ease of service and reduced downtime.
