Hitachi worldwide sales of more than 240 used for dredging engineering excavator, similar to figure EX1900-6 installed on the tank in excavator. This four excavator with cummins diesel engine. Independently by Hitachi hydraulic system design, the company also produces the corresponding hydraulic components. EX1200-6 excavator with cummins 6 cylinders water-cooled QSK23 - including C, diesel engine displacement of 23.15 liters, rated at 1800 RPM net power of 552 kw (567 kw) rated total power. The engine for three Hitachi variable displacement swashplate axial piston pump.

EX8000-6 excavators carry two cummins QSKTA60 - CE, diesel engines, each engine displacement is 60 litres, rated at 1800 RPM net power of 1450 kw (total power of 1450 kw). The excavator adopts 16 Hitachi variable displacement axial piston pump is front end fittings, driving power and rotation drive system.
