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.
Truckstop.com and ProMiles have expanded the Heavy Haul Load Board with route-based quoting for oversize and overweight freight.
