Doosan DL420

June 2010 Vol. 65 No. 6

The new DL420 articulated wheel loader boasts a larger, more powerful diesel engine than the model DL400, which it replaces.

With a bucket capacity of 5.2 cubic yards, the DL420 is designed to take on a wide range of material handling tasks. The 49,163-pound DL420 is powered by a 659-cubic inch, 6 cylinder turbocharged Cummins QSM11 electronically-controlled engine with high pressure unit injector system and a state-of-the-art combustion system. Emissions are well below Tier 3 regulatory limits.

The engine develops 280 horsepower at 2,000 rpm and offers maximum torque of 1,070 pound-feet at 1400 rpm for optimal traction and breakout force in loading-transport-handling applications. Depending on the application, the operator can choose between two working modes (standard or economy) for either maximum productivity or minimum fuel consumption. A robust Z-bar lifting system provides a standard bucket breakout force of 47,210 pounds, among the highest in its size class. This results in higher stripping force and greater productivity when working in hard materials. The turning radius at bucket edge is 22 feet 11 inches at the maximum steering angle of 40 degrees. www.doosanequipment.com
