Doosan Infracore Construction Equipment launched its new DA40 articulated dump truck (ADT), the first in a new family of Doosan ADTs offering increased engine power and torque, higher payloads, lower fuel consumption, enhanced operator comfort and faster travel speeds, according to the company.
Powered by a 6-cylinder interim Tier 4 compliant diesel engine with a gross power output of 500 hp at 2100 rpm, the new DA40 offers a 10-percent increase in engine power compared with the previous MT41 model. With a 22-percent increase in gross torque to 1,750 lb. ft. at 1300 rpm, the torque available in the DA40 is “best in class” in the ADT market.
Contributing to the overall 8-percent reduction in fuel consumption is the new transmission offering 8 forward and 4 reverse speeds. The new transmission improves the transfer of power from the engine to the wheels for outstanding traction. To withstand the increased power, the driveline dimensions and cooling capacity of the truck have been increased.
“To reflect the complete integration of the Doosan Moxy ADT product line into the Doosan Heavy equipment offering, the new ADTs will no longer include Moxy branding,” said Aaron Kleingartner, Doosan marketing manager. “The four new models will carry only the Doosan brand, rounding out a complete package of excavators, wheel loaders and articulated dump trucks for the construction equipment market.
“Doosan ADTs have permanent 6-wheel drive for equal power distribution while the free-swinging rear tandem bogie offer excellent driving performance in difficult terrain,” he said. “A unique articulation system with a forward-mounted turning ring allows equal weight distribution even during maximum turning to ensure maximum traction. An independent front suspension is a unique feature of the Doosan ADT, which provides maximum ground contact and shock absorption. To meet the latest emissions regulations, the new ADTs will be equipped with selective catalytic reduction technology.”
