Doosan Construction Equipment is launching the new DA30-7 and DA45-7 Stage V compliant articulated dump trucks (ADTs).
The new DA30-7 and DA45-7 replace the previous DA30-5 and DA40-5 Stage IV models, respectively. The DA30-7 has a payload of 28t, while that of the DA45-7 is 41t.
The DA30-7 is powered by the new Scania Stage V compliant DC09 9-litre diesel engine providing 276 kW (375 HP) of power. The DA45-7 is driven by the new Scania Stage V DC13 13-litre diesel engine with an output of 368 kW (500 HP).
The new Scania engines have undergone two years of highly intensive testing in exacting construction and mining environments. Whilst the core of the Scania engines has not changed, 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, 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 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.
The cabs on the ADTs have new comfortable hand grips and foot rests and an improved layout for the display that is easier to use.
As well as these changes, Doosan said that the new Stage V models offer many more features, one of the most eye-catching of which is a new design for the front frame and bonnet components on the trucks, created by the Doosan Design Team in accordance with the latest trends in the market.
“The new dynamic look given to the Stage V ADTs reflects the high performance, power and robustness of the Doosan ADT range and aligns even more closely with the rest of the market-leading range of construction equipment from Doosan,” the company stated.
“Together with the visual changes there are a number of functional changes on the new ADTs which 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 for 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 will help them to place optimal loads in the ADTs to ensure excellent productivity and low 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, 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. New improved maintenance access will also 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.
