Doosan Excavator DX420LCA (doosan)
DX420LCA provides incomparably superior productivity thanks to outstanding engine and pump power. 10~20% better digging force than competitors makes great digging performance in heavy quarry and mining job site.
One of the most important factors when choosing equipment is its uptime. DX420LCA maximized uptime by improving quality, reliability & durability while further facilitating maintenance.
The brains of the hydraulic excavator, the e-EPOSTM (Electronic Power Optimizing system), have been improved, through a CAN (Controller Area Network) communication link, enabling a continuous exchange of information between the engine and the hydraulic system. These units are now perfectly synchronised.
