Improved new articulated dump truck
First publishedin Aggregates Business Europe
Building on the success of the MT31 model which it replaces, the new Doosan DA30 articulated dump truck (ADT), which has a payload of 28tonnes, is said to offer many new features.
Driven by the five-cylinder Scania DC9 Stage IIIB compliant diesel engine with a gross power output of 276kW, the DA30 offers an 8% increase in engine power compared to the MT31.
In combination with the greater engine power, the DA30 also has 30% more gross torque (1,873Nm at 1,300rpm) to produce the powerful rim pull required to work in extreme hauling conditions.
The increased engine power is combined with SCR (Selective catalytic reduction) and the new ZF transmission offers eight forward and four reverse speeds. The fully automatic transmission with smooth Tiptronic gear-shifting (both automatic and manual gear functions are available) allows the operator to concentrate on working conditions and improves the transfer of power from the engine to the wheels.
“As well as permanent six-wheel drive, the DA30 also has a free-swinging rear tandem bogie designed to ensure that all six wheels are in continuous contact with the ground, enabling the truck to operate on very rough and soft terrain,” says Doosan.
The DA30 has a new cab providing more space and improved visibility for the operator, noise levels and a fully automatic climate control system. For easier operation, Doosan has introduced new electronic systems and simplified fingertip controls with a digital display of all desired machine functions.
