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 172-horsepower DL250-5 and DL250TC-5 (tool carrier) wheel loaders replace the “dash-3” (Tier 4-Interim) models, and have a Tier 4-compliant Doosan DL06 diesel engine.
DX140W-5, DX190W-5 and DX210W-5 wheeled excavators (132, 168, and 186 horsepower, respectively) replace the company’s “dash-3” Tier 4-Interim models.
