Doosan’s Stage 5 upgraded DA30-5 and DA40-5 ADTs

Doosan is launching Stage V compliant versions of its 30tonne DA30 and 40-tonne DA40 articulated dump trucks.

Doosan says that the DA30 and DA40 were upgraded in 2018 with a range of new features including a cab, a self-levelling front suspension and a tandem bogie system.

The Stage V models now have Scania 9 and 13 l engines after two years of very intensive testing in exacting construction and mining environments, says the company. There is a new positioning of the diesel and AdBlue tanks. These, also, are now much lower than before, allowing the operator to fill both tanks while standing next to the machine, meaning safer operator ground-level filling.

The greasing system has also been relocated to make it easily accessible from ground level. Space has been provided above the automatic lubrication system – which is standard – for additional grease cartridges and a filling pump.

In addition, the transmission filters have been installed close to the greasing system, where they are also very easy to access, says the company. All of these systems are protected to ensure that any excess drops of oil/grease are collected and can be removed during service and maintenance.

Like all Doosan ADTs, the new models feature an articulation hinge positioned behind the turning ring to provide equal weight distribution to the front axle even during maximum steer articulation. This combined with a free-swinging rear tandem bogie ensures equal distribution of weight to each wheel and guarantees permanent six-wheel contact and drive for equal power distribution.
