Latest Tier 4 Final/Stage IV articulated dumptrucks deliver superior fuel efficiency and load-carrying ability

FOLLOWING the latest field tests on new Tier 4 Final/Stage IV machines, Doosan Infracore Construction Equipment say exceptional fuel efficiencies and load-carrying abilities provide a significant reduction in cost-per-tonne rates for their DA40 and DA30 articulated dumptrucks.

The DA40 dumptruck (Tier 4 Final/Stage IV version) was tested with a new tracking and management system, which helped deliver an average fuel consumption rate of 17 litres/h – an improvement on the already impressive figures for the Tier 4 Interim model, which, Doosan say, has outperformed other similar machines on the market by up to 15% and, in some cases, has carried up to 10% more load.

Ewen Gilchrist, sales and marketing director for the Doosan ADT range, said: ‘The outstanding fuel efficiency of the Doosan ADT range is down to a combination of features, including a new Scania SCR diesel engine and ZF transmission improving the transfer of power from the engine to the wheels for superior traction.

‘When combined with an enhanced rear differential system, this reduces engine revolutions per minute and further increases machine durability. As a result, customers benefit from reduced cost per tonne with the Doosan ADT range.’

The Doosan DA40 ADT has a top speed of up to 58 km/h (36 miles/h) and an increased body capacity of 24.4 cubic metres, while the payload has been boosted to 40 tonnes without a tailgate, representing an increase of more than 15% over the payload of the previous MT41 model from Doosan.

All Doosan ADTs feature an articulation hinge positioned behind the turning ring to provide equal weight distribution to the front axle even during maximum steer articulation. This, together 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 and good performance on difficult terrain.

‘As commonly requested by ADT users, we will be supporting the high machine performance with a new tracking system specifically for our ADT range, that will provide full information on payloads, fuel consumption and cycle times,’ commented Mr Gilchrist.
