Doosan Infracore Construction Equipment has launched the new DA40 articulated dump truck (ADT), offering increased engine power and torque, higher payloads, lower fuel consumption, enhanced operator comfort and faster travel speeds

 Using quality components from world-class suppliers such as Scania, ZF, NAF, Parker and Rexroth, the new Doosan ADTs are optimised for extreme off-road performance. The exceptionally flexible and agile undercarriage, which is designed to ensure that all six wheels are in permanent contact with the ground, means that Doosan trucks can operate on very rough and soft terrain on construction sites such as road projects and mass excavation hauling as well as in mining and quarrying applications.

The new articulated dump trucks complement Doosan’s wide range of excavators and wheel loaders, allowing Doosan to offer a one-stop 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.

Like all Doosan heavy equipment, 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 our dealers and to ensure the customer experiences maximum uptime from their machine.

 

The new DA40: Power, Performance, Productivity and Fuel Efficiency

Powered by the 6-cylinder Scania DC13 Tier 2 diesel engine with a gross power output of 368 kW (500 HP) at 2100 rpm, the new DA40 offers a 10 per cent increase in engine power compared to the previous MT41 model. With a 22 per cent increase in gross torque to 2373 Nm (1750 lb ft) at 1300 rpm, the torque available in the DA40 is ‘best in class’ in the ADT market.

Contributing to the overall 8 per cent reduction in fuel consumption is the new ZF transmission offering eight forward and four reverse speeds. The new transmission improves the transfer of power from the engine to the wheels for outstanding traction. To withstand the increased power, the driveline dimensions and cooling capacity of the truck have been increased.

The DA40 combines ‘best-in-class’ fuel consumption with a higher top speed of 58 km/h (36 mph). The DA40 also has an increased body capacity of 24.4 m³, and the payload has been boosted to 40 metric tonne without tailgate, an increase of more than 15% over the payload of the MT41. The higher speeds and payloads will allow the customer to increase profits from their mining, quarrying or earthmoving operations.

 

6-wheel traction and outstanding rough and soft terrain capabilities

The DA40 has permanent 6-wheel drive for equal power distribution while the free-swinging rear tandem bogie and the special articulation system offer excellent driving performance in difficult terrain. The sloping body design 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. The combination of the unique tandem bogie and the sloping rear frame results in ‘best in class’ rough and soft terrain capabilities and avoids the need for electronic aids such as traction control.

To handle the increased payload as well as provide a smoother ride for the operator, the DA40 has a completely new hydro-gas front suspension. This independent front suspension (there is no rigid axle) is a unique feature of the Doosan ADT which allows for free movement on one side, without movement on the opposite side, providing maximum ground contact and shock absorption.

The articulation hinge is positioned behind the turning ring to provide equal weight distribution even during maximum turning and ensure maximum contact between the front wheels and the ground for optimum traction.

Thanks to the high engine power and torque, the improved ground clearance and the efficient powertrain, the DA40 delivers ‘best-in-class’ rim pull in extreme hauling conditions. Like all Doosan ADTs, the DA40 features a powerful engine brake and hydraulic transmission retarder as standard. The wet brakes offer a long service life and sealed protection from the environment and, with oil-cooled multiple disc brakes on all the wheels, the safety of the operator is never compromised.
