South Korean industrial equipment maker Doosan has launched a "smart" crawler excavator called the DX225LC-7X that has new features such as Full Electric Hydraulic (FEH) technology.  

Doosan said the DX225LC-7X's FEH technology is a VBO system without pilot pressure lines. Joysticks and pedals are fully electric, but give the operator the same feeling as hydraulic joysticks.

Oher standard features of the DX225LC-7X include integrated 2D Machine Guidance and Semi-Automatic 2D Machine Control. The integrated machine guidance system on the DX225LC-7X uses sensors mounted on the front and body to recognize the location of each working device and inform/guide it for the operator.

In the on-board machine control system, the sensors mounted on the front and body recognize the location of each working device and support/adjust the front operation to the work as planned. In this way, when the operator uses the arm, bucket or boom, they follow the target line.

Thanks to the inclusion of a laser receiver, the system will always receive the reference point, even when the machine changes position, without the operator having to reset the reference point every time the machine is moved.

A Weighing System and Lift Assist function also measures and displays the current weight of the bucket as the operator is loading materials and warns the driver when the total loading weight exceeds the target.
