Doosan has launched their new DX-7 Series Excavators. With numerous upgrades and improvements across the board, the company says that the new line-up represents “the best combination of performance, smooth and intuitive controls, sustainable manufacturing and unbeatable value for money for customers.”
The new range starts with the 14.4 tonne DX140LC-7 and extends right up to the 80 tonne DX800LC-7 with the 400 kW Perkins 2506J Stage V engine.
So, What’s New Across the Range?
360° cameras and ultrasonic object detection for full visibility around the machine. The new excavators are safer than ever, allowing operators to focus on their job while minimizing risks.
Introducing 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.
Doosan’s new smart hydraulic system introduces a priority valve, providing optimal flow to the attachment, when both the arm and attachment are working simultaneously. This results in 30% better work efficiency.
The latest Stage V-compliant engines boost fuel efficiency, while an improved combustion system reduces particle emissions. This increases the lifetime of the diesel particulate filter (DPF), with no maintenance required until 8,000 hours.

In addition, the DX140LCR-7 is a reduced tail swing model, allowing operators greater flexibility where space is a premium without sacrificing performance. The DX140LCR-7 also has a new counterweight design that offers enhanced service accessibility.
