Transmission accomplished: upgraded ADTs offer greater fuel efficiency

TEREX Trucks’ TA300 articulated hauler has been updated with a new transmission, which has led to improvement in fuel efficiency, performance, productivity and operator comfort, the manufacturer claims.

The 28-tonne machine will now incorporate the EP320 transmission from ZF as standard. This, according to Terex Trucks, has resulted 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 features eight forward gears, along with four reverse gears, higher overall gear ratio speed, equal ratio steps between gears and optimised gear shifting with partial load shifts, all of which aims to offer smoother gear shifting and thereby higher levels of operator comfort. The TA300 also has true independent front suspension as standard, enabling “excellent” traction control and “maximum productivity in the most challenging of conditions”. The hauler’s maximum speed has increased to 34 mph, up from 31 mph and it now comes with long life transmission fluid, which Terex describe as 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 job sites, working in a variety of conditions. Operators have had nothing but praise for the upgraded machine. Among some of the most commonly citied benefits are the improved fuel efficiency and performance, as well as the smoother gear shift quality.”

The updated TA300 will initially be available from August in Europe and North America.
