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.
Three E Series articulated dump trucks have been updated with Tier 4-Final John Deere PowerTech diesels.
The 735C, 740C EJ, and 745C articulated dump trucks have rated payload capacities of 36, 42 and 45.2 tons, respectively.
The Doosan line of severe-duty buckets for crawler excavators is approved for use on the DX140LC-5 through DX530LC-5 models.
The DL200-5 wheel loader is Doosan’s first with hydrostatic drive, and replaces the Dash-3 versions with a Tier 4-Final engine rated at 142 horsepower.
