The latest version of the Doosan® DA30-5 includes numerous updates to the truck’s performance, operator comfort, controllability of the machine, ease of maintenance and fuel efficiency. A significant development in the DA30-5 ADT – rated in the popular 30 metric ton size class – is a new front suspension. This has been updated to a hydro gas, self-leveling system to provide superior performance and greater shock absorption. Combined, these suspension system features allow for better driving comfort, especially when the truck is being driven while empty on a construction jobsite or at a mining operation. From a technical standpoint, the truck’s hydro gas cylinders are connected to pressure accumulators — the accumulators and hydraulic system replace the previous shock absorbers and a rubber spring. The suspension of the updated DA30-5 includes a self-leveling feature and the ability to change the characteristics by adjusting the pressure.

The DA30-5 cab interior has been redesigned to provide better ergonomics and more operator comfort, taking into consideration input from current owners and operators. There are more than a dozen new features inside the completely new layout of the Doosan DA30-5 cab to enhance the driving experience. Updates to the truck’s vehicle control unit (VCU) include more robust hardware, better processors, more input channels for customized functions or further technology developments and high quality, automotive style connectors. 

Furthermore the updated DA30-5 has an articulation hinge positioned behind the turning ring to provide equal weight distribution to the front axle even during maximum steer articulating. This, together with a unique free swinging rear tandem bogie, ensures equal distribution of weight to each wheel and allows permanent 6 wheel contact and drive for equal power distribution and excellent performance on difficult terrain. The forward turning point, the tandem bogie and the truck’s sloping rear frame results in exceptional rough and soft terrain capabilities and avoids the need for electronic aids such as traction control.

Powered by a 370 net horsepower diesel engine, the updated DA30-5 meets Tier 4 emission regulations through the use of both SCR and EGR technologies with an electronic brake system — one of four brake systems on the trucks. Doosan Tier 4-compliant ADTs do not need a diesel particulate filter (DPF) to meet the emission regulations in North America.
