Doosan DA30 ADT is redesigned with a 365-horsepower Tier 4-Interim engine with 8 percent more power than the predecessor MT31. Torque has been pushed to 1,381 ft.-lb. at 1,300 rpm, a 28-percent jump. Top speed is now 34.2 mph for the truck. The transmission has eight forward and four reverse speeds, and improves the transfer of power to the wheels for better traction, Doosan says. It has permanent six-wheel drive. A special articulation system includes an articulation hinge positioned behind the turning ring to provide equal weight distribution to front wheels. Doosan’s 48 Hour Parts Guarantee provides two-day direct delivery of “machine-debilitating” parts or Doosan will pay for a replacement machine rental.
Models DA30-5 and DA40-5 fit in the 28- and 40-metric-ton class, with payload ratings of 61,729 and 88,185 pounds, respectively.
