Doosan develops new top-of-the-range digger

Doosan will introduce a new range-topping tracked excavator in the shape of the 71.5 tonne DX700LC. The machine offers 33.3 tonnes of digging force at the bucket and a maximum dig depth of 7.77 m. The maximum dump height is 8.18 m.

Power comes from a 345 kW six-cylinder Isuzu engine, which is cooled by the Doosan Cooling Fan Control (DCFC) system that matches fan speed to the cooling requirement.

The hydraulic system has four modes - standard, economy, power and lifting - to suit different applications, while the boom and dipper cylinders are cushioned to provide smooth operation at the end of the stroke.
