The manufacturer says that the new DX-7 models combine performance, smooth and intuitive controls, sustainable manufacturing and value for money for customers.

The launches include three new 23-25 tonne Stage V compliant crawler excavators - the DX235LC-7, DX235LCR-7 and DX255LC-7 models - that are suited to quarrying and mining applications.

Gilles Bendaoud, VP sales and marketing at Doosan Infracore Europe, says that the new models in the DX-7 range bring improvements in four key areas - safety, efficiency, comfort and sustainability.

In terms of safety, 360° cameras and ultrasonic object detection provide full visibility around the machine, allowing operators to focus on their job while minimising risks.

For comfort there is an all-new, spacious cab with premium seating equipped with heating and cooling controls. In addition, the operator has a large 8-inch user-friendly touchscreen monitor through which they can input and change all settings needed during daily operation.

Bendaoud says efficiency is improved through a new smart hydraulic system that introduces a priority valve, providing optimal flow to the attachment when both the arm and attachment are working simultaneously. This is claimed to result in 30% better work efficiency.
The latest Stage V-compliant engines boost fuel efficiency, while an improved combustion system improves sustainability and reduces particle emissions. This increases the lifetime of the diesel particulate filter (DPF), with no maintenance required until 8,000 hours.

Two other larger models - the DX490-7 and the DX530LC-7 - have previously been launched in the DX-7 range that are suited for quarrying and mining applications, offering higher digging force and high productivity.
