Hard Hitter – Hitachi ZX690LCR-7
Eoghan Daly visits what is believed to be the first Dash 7 version of Hitachi Construction’s 690LCR excavator to go into service in Europe, operating at the Live Work Grow at Central Park site in Dublin.
The bright orange machine is owned by Shannon Valley Group and is powered by a Stage 5 emissions-compliant engine producing 348kW and 2,050Nm of torque at 1,300rpm. Weighing 71.7 tonnes in mass excavation spec, the 690LCR demonstrated its effectiveness at breaking up hard granite with its Rammer C130 and Epiroc hydraulic hammer attachments.
Veteran operator Tom Reilly told Eoghan, “Hitachis have always been real operators’ machines and this new Dash 7 is even better. Like always, it has a great control layout and is very smooth on the levers too.”

To get there, this particular machine was transported from Komatsu’s Osaka factory in parts to the port of Zeebrugge in Belgium. The components were then driven 2,300km on trucks to Komatsu’s Baltem As dealer in Estonia, where it was fully assembled in the on-site workshop.
