Doosan launches DA30 articulated dump truck
The new Doosan DA30 articulated dump truck is one of the latest redesigned machines offering increased engine power and torque, higher payloads, lower fuel consumption, enhanced operator comfort and faster travel speeds.
The machine features a six-cylinder interim Tier 4 compliant diesel engine with a gross power output of 365 horsepower, an eight percent increase in engine power compared to the previous MT31 model. It has a 28 percent increase in gross torque to 1381ft.-lb. at 1300 rpm, and a higher top speed of 34.2 mph. Contributing to the overall eight percent reduction in fuel consumption is the new transmission offering eight forward and four 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.
The agile undercarriage, designed to ensure that all six wheels are in permanent contact with the ground, means the DA30 can operate on very rough and soft terrain on construction. The sloping design of the DA30 enhances the stability of the machine due to its low center of gravity and allows fast and easy dumping, even in the most demanding conditions. Permanent six-wheel drive provides equal power distribution while the free-swinging rear tandem bogie and the special articulation system offer excellent driving performance in difficult terrain.
The DA30 features a powerful engine brake and hydraulic transmission retarder as standard. The wet brakes offer a long service life and sealed protection from the environment and, with oil-cooled multiple disc brakes on all the wheels, the DA30 can handle various operating conditions.
