DA30 Articulated Dump Truck

Doosan

May 1, 2012 - Equipment

Powered by a 6-cylinder interim Tier 4-compliant diesel engine with a gross power output of 365 hp, the Doosan DA30 articulated dump truck offers an 8% increase in engine power compared to the previous MT31 model. The model features a 28% increase in gross torque to 1381ft.-lb. at 1300 rpm and a higher top speed of 34.2 mph.

Contributing to the overall 8% 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 improved traction. To withstand the increased power, the company increased the truck’s driveline dimensions and cooling capacity.

The DA30’s undercarriage was designed to ensure all six wheels are in permanent contact with the ground, meaning the truck can operate on very rough and soft terrain. The sloping design of the DA30 enhances the stability of the machine thanks to its low center of gravity and allows fast and easy dumping. 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, according to the company.

The articulation hinge is positioned behind the turning ring to provide equal weight distribution to front wheels, even during maximum turning, and ensures full contact between the front wheels and the ground for optimum traction. The DA30 uses two hydraulic shock absorbers and tall rubber springs on each side, along with no rigid axle, to provide a totally independent suspension.

Like all Doosan ADTs, 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.

The cab of the DA30 can be tilted backward to provide easy access to components for hassle-free routine maintenance. A fully automatic central greasing system and rear view camera are standard.

The DA30 — like every new Doosan machine — is covered by a 48-hour parts guarantee. The program guarantees that if a “machine-debilitating” part is needed, Doosan will deliver it directly to the end user within two business days, or Doosan will pay for a replacement machine rental. The 48 Hour Parts Guarantee is subject to carrier delivery restrictions and/or governmental agency delays.
