The TA300 articulated dump truck has a ZF EP320 transmission that improves fuel efficiency by 5 percent over its predecessor. It has eight forward gears, four reverse, higher overall gear ratio spread, equal steps between gears, and optimized gear shifting with partial load shifts.

The 30-ton ADT also has true independent front suspension. Maximum speed has been increased to 34 mph, from 31.
