Doosan launch two new Stage V Excavators

Doosan DX530LC-7 excavator

New DX490LC-7 and DX530LC-7 said to offer highest productivity in the 50-tonne class

DOOSAN have launched the new DX490LC-7 and DX530LC-7 Stage V crawler excavators, which are said to set a new benchmark for the 50-tonne class, providing significantly improved performance compared with the previous Stage IV models and offering the strength and productivity needed for heavy-duty work in quarrying, mining, demolition, utility and general construction projects.

To meet Stage V engine emission regulations, the DX490LC-7 and DX530LC-7 are powered by the new Scania DC13 Stage V compliant diesel engine, which provides a power output of 294kW (394hp). Moreover, the engine offers a new solution to exceed Stage V with super-efficient DOC/DPF+SCR after-treatment technology to ensure minimal emissions.


Thanks to the new technology, maintenance of the diesel particulate filter (DPF) has been greatly reduced, with a six times longer automatic regeneration interval (60h) and an ash-cleaning interval that is twice as long at 8,000h, compared with the previous DPF in the DX-3 generation machines. From the cab, the operator is now able to see, via the gauge panel, the amount of ash build up in the DPF and whether a regeneration has been successful.
In the DX490LC-7 and DX530LC-7, the enhanced performance of the Scania DC13 engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-Ecopower+) and new-generation Smart Power Control Technology (SPC3), providing an overall fuel efficiency increase of 11%.

Increased pump capacity and the higher power of the engine produces up to an 8% increase in productivity, delivering what is said to be the best-in-class performance in the 50-tonne market.

Four power modes (P+, P, S or E) are now available on both machines, helping to simplify the operation of the new excavators compared with the more complex choice of eight power modes and SPC combinations in the previous generation of machines.

For operator comfort and ease of operation, the new cab on the DX490LC-7 and DX530LC-7 models, like the new Doosan 30–40-tonne Stage V models, has a new, high-quality seat and offers more features as standard than other machines on the market, ensuring superior controllability and high precision in all applications.

As standard, 360-degree cameras provide full all-round visibility and allow the operator to see a top-down view of the area outside the machine. The camera array comprises a front camera, two side cameras and a rear camera. The camera display is separated from the gauge panel.

In addition, the new DX490LC-7 and DX530LC-7 models are factory-installed with Doosan’s state-of-the-art DoosanCONNECT wireless fleet-monitoring system.

Also, as a leading brand in information and communications technology (ICT), Doosan have taken a significant step forward by offering customers lifetime free cellular service with all DX-7 generation excavators. This means that customers can use the DoosanCONNECT service without any limitation, as long as they use the service with a cellular network. Satellite service will be offered free of charge for a three-year period.
