New Doosan DA30 articulated dump truck



The MT31 articulated dump truck is being phased out with the introduction of the new Doosan DA30 ADT) which has a payload of 28 tonnes and several features in response to customer demands for ever increasing power and performance. With the high cost of fuel, customers are also asking for the most fuel efficient solution.

Performance, productivity and fuel efficiency

Driven by the 5 cylinder Scania DC9 Stage IIIB compliant diesel engine the gross power output of 276 kW (375 HP) is 8% more than the older model. More engine power enables more torque - now 1,873 Nm/1300 rpm - an increase of 30%.

New engines are necessary to comply with emission regulations but if the power and performance is optimised along with the transmission and hydraulics, significant benefits can accrue.

Doosan has done all that is necessary and claim that the increased engine power, combined with SCR technology, delivers the ‘best-in-class’ fuel consumption with a higher top speed of 58 km/h (34 mph).

The 5 cylinder Scania DC9 Stage IIIB compliant diesel engine the gross power output of 276 kW (375 HP) is 8% more than the older modeContributing to the overall 8% reduction in fuel consumption (under standard working conditions) is the new ZF transmission with 8 forward and 4 reverse gears.

The 5 cylinder Scania DC9 Stage IIIB compliant diesel engine the gross power output of 276 kW (375 HP) is 8% more than the older model.

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.

The DA30 has permanent 6-wheel drive with a free-swinging rear tandem bogie designed to ensure that all 6 wheels are in continuous contact with the ground for maximum traction in demanding ground conditions. Turning radius is 7.6 8 m. Body dump angle is 70° and width is 2,900 mm.

The articulation hinge is positioned behind the turning ring to provide equal weight distribution even during maximum turning and ensure full contact between the tyres and the road surface.

Like its predecessor, the DA30 features an independent front suspension (there is no rigid axle), a unique feature of the Doosan range, which allows for free movement on one side, without movement on the opposite side, giving maximum ground contact and shock absorption.
