Updated Articulated Trucks for North America

Doosan released the 280-kW DA30-5 and the 373-kW DA45-5 articulated dump trucks to North American markets. The units are based on predecessor models in the line and have numerous updates to improve performance and reliability, the company reported. Both units feature a hydro-gas self-leveling suspension system. Both have a tandem rear bogie and limited slip differential. The latter transfers power to the left and right front wheels, providing the highest torque to the wheel with the best grip. Both models have a new brake package for improved reliability, and an updated grease distribution system that lowers grease requirements by as much as 50%. An active payload measuring system comes standard on both trucks. An LCD screen in the operator cab gives each load’s weight. An exterior red-yellow-green light signals to excavator and loader operators, indicating how close the current load is to the optimal size.

The models also feature a new transmission adjustment lever, allowing operators to choose between set levels of retarder force. The cab offers better ergonomics over predecessor models in the line. Features include a new dashboard and an updated vehicle control unit with a faster processor. DoosanCONNECT telematics, machine health diagnostics tools, are offered for free. With it, fleet owners and managers can remotely monitor machine location, fuel usage, engine temperatures and work time. The DA30-5 has a capacity of 16.8 m3, and the DA45-5 has a capacity of 24.4 m3. Both have a maximum speed of 55 km/hour.
