Doosan Construction Equipment is launching two new Stage V compliant articulated dump trucks (ADTs).

The engines on the new DA30-7 and DA45-7 machines are designed to comply with European Stage V emissions standards for non-road vehicles. The two new ADTs replace the previous DA30-5 and DA40-5 Stage IV models. The DA30-7 has a payload of 28 tonnes, while the DA45-7 can carry 41 tonnes (one tonne more than its predecessor the DA40-5).

The DA30-7 is suitable for construction sites and groundworks and is powered by the new Scania Stage V compliant DC09 9 litre diesel engine providing 276kW (375hp) of power. The DA30-7 is being demonstrated at this week's Doosan Quarry Days event at Bělice Quarry near Prague, Czech Republic. The three-day event takes place from September 17-19 and will be attended by nearly 500 customers, dealers and press.

The DA45-7 is targeted at the quarrying, mining and construction sectors and features the new Scania Stage V DC13 13 litre diesel engine with an output of 368kW (500hp).

Doosan says the main difference in the new engines from their predecessors is the improved after-treatment system.

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 which are all incorporated in the new DA30-7 Stage V model. A similar process has been applied in the new DA45-7 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. The cabs on the ADTs have new comfortable hand grips and foot rests and an updated layout for the display which is designed to be easier to use.

The two new Stage V models offer a number of other new features designed to improve safety, comfort and serviceability. These include a new positioning of the diesel and AdBlue tanks. The latter are now much lower than before, allowing the operator to fill both tanks whilst standing next to the machine (‘ground level filling’).  

The new ADTs are equipped as standard with a real-time payload measuring system with a light indication for excavator operators, which is designed to help them to place optimal loads in the ADTs to maximise productivity and fuel consumption.

The greasing system has also been relocated to make it easily accessible from ground level. Space has been provided above the automatic lubrication system (which is standard) for additional grease cartridges and a filling pump.

In addition, the transmission filters have been installed close to the greasing system to provide ease of access. All of these systems are protected with the intention of ensuring that any excess drops of oil/grease are collected and can be removed during service and maintenance. Doosan says the improved maintenance access will help operators to perform daily checks faster and more safely.

Both of the new machines are equipped with additional external round hand rails to prevent accidents and hazardous situations. Inside the cab there is a new additional grip on the right-hand side for increased safety for the operator.

The electronic and hydraulic systems in the new trucks have also been upgraded to offer improved performance with extended functionality and new technology.

The new designs and developments in the two new Stage V ADTs have been introduced following intensive market analysis, customer visits, interviews with operators and additional feedback gathered by the Doosan ADT Product and R&D teams at the company’s ADT plant in Elnesvågen, Norway.
