Xara Developers, Ghana

Xara Developers is constructing a sea defence revetment in West Africa to protect local communities and their resources from tidal damage. The 5.5m-high, 2km-long coastal defence project is on the edge of the Gulf of Guinea near the town of Aboadze in Ghana.

A ZX470LCH-5G is one of three Hitachi excavators used for earthmoving, moving large rocks, keeping areas of the beach clear and creating small stockpiles of rocks. Project Manager Niels Elsnab says: “The Hitachi machines work very well and we have minimal downtime. They’re also durable, which is vital for this type of work.”

Sophisticated hydraulics

The HIOS IIIB hydraulic system of the ZX470LCH-5G results in 8% reduced fuel consumption and reduced CO₂ emissions (compared to the previous model). It also increases the operating speed of the excavator thanks to swift front movements.

Swing torque, boom lifting capacities, and traction, arm digging and bucket digging forces have all been increased on the ZX470LCH-5G, enhancing its performance. Switching attachments is also easier – you can change over valves, adjust extra circuit flow and check settings using the multifunctional monitor in the cab.
