The Hitachi ZX225USRLC-3 excavator was used to dig deep below ground in paris
A 233 Hitachi excavator has enabled the creation of a subterranean six-floor car park in the centre of Paris.
The ZX225USRLC-3 was used to dig deep below ground in the French capital and remove 65,000m³ of earth before construction of the facility could begin.
For Saperfe Travaux Publics, a sub-contractor working on the project, the Hitachi machine was the only specialist equipment required. The clamshell telescopic arm of the ZX225USRLC-3 can reach depths of up to 25m.
At the site, the small footprint achieved with the zero-tail swing maximised productivity as it enabled trucks to stop directly adjacent to the excavator for immediate loading. As a result, the Hitachi excavator loaded each of the 13 trucks productively.
According to operator Marco Ferreira, the ZX225USRLC-3 was ideal for digging deep below ground and beyond the range of conventional excavators.
"The extension/retraction device in the arm moves quickly to enable a smooth telescopic movement. The sliding cab and extended window make it comfortable to operate," he said.
According to Hitachi, the ZX225USRLC-3 also coped well with the earth's high-water content which presented the toughest challenge. As the ground was so soft, a network of pipes was used to hold the car park's underground structure in place.
The excavator had to work in and around these pipes, which proved a delicate task.
Site manager Laurent Petain explains: "The excavator worked in 5.5m deep sections at a time and had to be extremely precise." Supplied by official French Hitachi dealer Payen, the ZX225USRLC-3 is the third Hitachi addition to the Saperfe fleet. The company also has a ZX210W-3 wheeled excavator and a ZX25 mini excavator.
