Doosan has launched the new DX225LC-7X – the company’s first ‘Smart’ crawler excavator, designed to help operators work faster and more efficiently. To facilitate this, the DX225LC-7X offers a number of new features as standard, including Full Electric Hydraulic (FEH) technology. FEH is similar to the company’s VBO (virtual bleed off) system that we call Doosan D-ECOPOWER.
The FEH is a VBO without pilot pressure lines. The joysticks and pedals are fully electric but give the operator the same feeling as hydraulic joysticks.
FEH sends an electric signal to the controller and as such is more precise and provides faster information. Back pressure and energy loss are therefore eliminated, by delivering the exact amount of oil needed. As there is no pilot pressure, energy and therefore fuel is saved. In fact, FEH offers a very significant 8% less fuel burn compared to the VBO system. This is on top of the 7% decrease in fuel consumption already achieved in the standard DX225LC-7, compared to the previous DX225LC-5 model.
Other standard features of the DX225LC-7X include:
- Integrated 2D Machine Guidance
- Semi-Automatic 2D Machine Control
- Weighing System
- E-Fence Wall
- Laser Receiver
Additional features are in preparation:
- Upgrade to full Trimble GPS 3D optional
- Engcon Ready from Factory (Plug and Play)
- Tilting Bucket for 2D Machine Guidance
