New Stage V compliant ADTs from Doosan
Doosan introduce their new 28-tonne DA30-7 and 41-tonne DA45-7 articulated dumptrucks
DOOSAN Construction Equipment are launching the new DA30-7 and DA45-7 Stage V compliant articulated dumptrucks (ADTs), which replace the previous DA30-5 and DA40-5 Stage IV models, respectively.
The new DA30-7, which can carry a payload of 28 tonnes, is powered by the new Scania Stage V compliant DC09 9-litre diesel engine that provides 276kW (375hp) of power, whilst the 41-tonne payload DA45-7 is driven by the new Scania Stage V DC13 13-litre diesel engine, which has a power output of 368kW (500hp).
In 2018, the DA30-5 ADT was upgraded with a range of features including a new cab, a new self-levelling front suspension and a new tandem bogie system, all of which have been incorporated in the new DA30-7 Stage V model.
A similar process has been applied with the new DA45-7 Stage V machine, with a new cab and a semi-levelling front suspension that adjusts itself independently depending on the operating conditions to ensure a comfortable working environment for the operator.
As well as these changes, the new Stage V models offer many more new features, one of the most eye-catching of which is the new design for the front frame and bonnet components. The trucks’ new dynamic look reflects the performance, power and robustness of the Doosan ADT range and aligns even more closely with the rest of Doosan’s construction equipment line-up.
Together with the visual changes there are a number of functional changes on the new ADTs to improve safety, comfort and serviceability, including new positioning of the diesel and AdBlue tanks. These are now much lower than before, allowing the operator to fill both tanks while standing on the ground next to the machine.
The new ADTs are equipped as standard with a real-time payload measuring system featuring an indication light to help excavator operators place optimal loads in the trucks to ensure excellent productivity and low fuel consumption.
The greasing system has also been relocated to make it easily accessible from ground level, and space has been provided above the automatic lubrication system, which is fitted as standard, for additional grease cartridges and a filling pump. Also, the transmission filters have been installed close to the greasing system, where they are also very easy to access.
All of these systems are protected to ensure that any excess drops of oil/grease are collected and can be removed during service and maintenance. In addition, new improved maintenance access will help operators to perform daily checks faster and more safely.
For increased operator safety, both of the new machines are equipped with additional external round handrails, whilst inside the cab there is a new additional grip on the right-hand side.
Like all Doosan ADTs, the new models feature an articulation hinge positioned behind the turning ring to provide equal weight distribution to the front axle even during maximum steer articulation. This combined 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 excellent performance, particularly on difficult terrains, steep slopes, tight turns or a combination of all these conditions.
