Mining truck gets fuel economy and speed boost

Jon Lawson

Terex Trucks has updated its TA300 articulated hauler with the introduction of a new and improved transmission. The 28-tonne (30-ton) workhorse will now incorporate the latest EP320 transmission from ZF. 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. 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 optimised gear shifting with partial load shifts. All of this helps to ensure smoother gear shifting and thereby higher levels of operator comfort. The TA300 is also equipped with true independent front suspension as standard, further enhancing operator comfort and enabling excellent traction control and maximum productivity in the most challenging of conditions.

In addition to this, the hauler’s maximum speed has increased to 55 km/h (34 mph), up from 50 km/h (31 mph). As a result, customers can achieve faster cycle times and lower cost per tonne. Other operational features include automatic shifting with manual over-ride, a hydraulic integral retarder and a hydraulic power-shift longitudinal differential lock. Together, these help to ensure safe and productive operation, as well as reduced fuel and diesel exhaust fluid (DEF) consumption on job sites. It 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.
