New Doosan DA30 Articulated Dump Truck

Building on the success of the popular MT31 model which it replaces, the new Doosan DA30 articulated dump truck (ADT), which has a payload of 28 metric tonne, offers many new features to meet customer demands for increased power and performance, easier operation, increased fuel efficiency, enhanced driver comfort and faster travel speeds.
Performance, productivity and fuel efficiency
Driven by the 5-cylinder Scania DC9 Stage IIIB compliant diesel engine with a gross power output of 276 kW (375 HP), 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 (1873 Nm at 1300 rpm), to produce the powerful rim pull required to work in extreme hauling conditions.
The increased engine power is combined with SCR technology for 'best-in-class' fuel consumption with a higher top speed of 58 km/h (34 mph). Contributing to the overall 8% reduction in fuel consumption* is the new ZF transmission offering 8 forward and 4 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 6-wheel drive, the DA30 also has a free-swinging rear tandem bogie designed to ensure that all 6 wheels are in continuous contact with the ground, enabling the truck to operate on very rough and soft terrain.
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.
The sloping rear frame enhances the stability of the truck thanks to its low centre of gravity and allows fast and easy tipping, even in the most demanding conditions.
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.
Like all Doosan ADTs, the DA30 features a powerful engine brake and hydraulic transmission retarder as standard. The air-cooled multiple disc brakes on all wheels offer long service life and sealed protection from the environment.
Quality and reliability
Incorporating over 40 years of expertise in the ADT market and using quality components from world-class suppliers such as Scania, ZF, NAF, Parker and Rexroth, the new DA30 is part of a new generation of ADTs from Doosan optimised for extreme off-road performance.
Operator comfort and convenience
The DA30 has a new cab providing more space and improved visibility for the operator, 'best in class' 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.
Maintenance and service
For routine maintenance and service work, the cab can be tilted backwards to provide easy access to components. A fully automatic central greasing system and rear view camera are standard equipment.
One-stop shop solution
The new articulated dump trucks complement Doosan's wide range of excavators and wheel loaders, allowing Doosan to offer a one-stop shop solution for equipment to excavate, load and transport all types of materials. All Doosan ADT and heavy equipment products are supported by flexible financing packages from Doosan Financial solutions, offering 'tailor-made' solutions for purchasing Doosan products.
The new range of ADTs is supported by a regional sales and service operation with strategically located parts depots to service a worldwide network of Doosan dealers. All the depots have fully trained Doosan service and parts specialists to support the dealer and ensure the customer experiences maximum uptime from their machine.
