Doosan launches first ‘smart’ excavator
By Catrin Jones09 June 2022
Doosan has launched the new DX225LC-7X, which is said to be designed to help operators work faster and more efficiently.
The new DX225LC-7X smart model will include Full Electric Hydraulic (FEH) technology as well as integrated 2D machine guidance, e-fence virtual wall, weighing system, and laser receiver.
The company says that the Full Electric Hydraulic (FEH) technology is comparable to the D-Ecopower VBO (virtual bleed off) system that is incorporated on the standard DX225LC-7 model and all Doosan crawler excavators from the DX350LC-7 and above. The joysticks and pedals are fully electric, but give the operator the same feeling as hydraulic joysticks.
In the FEH system, Doosan says that an electric signal is sent to the central controller and as such is more precise and provides faster information. As the system does not utilise pilot pressure, energy is saved and there is a resultant fuel saving.
The FEH system offers 8% less fuel burn compared to the D-Ecopower VBO system – this is in addition to the 7% decrease in fuel consumption already achieved in Doosan’s standard DX225LC-7.
Doosan is hoping to provide additional features on the DX225LC-7X in the future such as a tilting bucket for 2D machine guidance, an upgrade to full Trimble GPS 3D, and engcon ready from factory (plug and play).
