The DX225LC-7 includes a 14% heavier 4.9-ton standard counterweight for working with large attachments and a new smart hydraulic system.

Doosan

Doosan offers the DX225LC-7 crawler excavator for construction and industrial projects. The DX225LC-7 is the first Doosan excavator of this size to feature Doosan’s innovative D-ECOPOWER virtual bleed off (VBO) technology, providing operators with 7% lower fuel consumption per hour than the previous Stage IV model, as well as smoother controls.

Heavier Counterweight for Work with Tiltrotators

In the DX225LC-7, the new features include a 14% heavier 4.9-ton standard counterweight for working with heavier attachments, such as tiltrotators. The heavier counterweight contributes to higher lifting and digging capacities compared to the previous generation model.

The DX225LC-7 also incorporates as standard a new lifting eye that forms part of the casting for the push link for the bucket attachment at the end of the arm. The new lifting eye has a maximum capacity of 5 tons and has a special bush insert to prevent deformation of the lifting hole.

With the new counterweight, the DX225LC-7 introduces a new smart hydraulic system that offers an improvement of around 30% in attachment work, compared to previous excavator models.

Tiltrotator Mode

There is a new tiltrotator mode on the control panel in the DX225LC-7, which can be selected to ensure optimized hydraulic flow and helps maximize the accuracy of tiltrotator work by eliminating back pressure.

Fine Swing Function

Another standard new feature is the fine swing function which minimizes the shaking that a lifted object undergoes at the start or stop of a swing movement with the excavator, to increase the safety of nearby workers and to prevent damage caused by the object falling from the excavator.
