Hitachi excavators tackle confined spaces

Hitachi has presented two new products at the Intermat exhibition in Paris, France.

The ZX135US-6 sliding arm excavator is designed for deep excavation projects in confined spaces. Hitachi said it can dig deeper than a 30 t standard model and has a significantly smaller footprint, which makes it ideal for urban projects.

This special application model was shown by Payen, an authorised dealer of Hitachi Construction Machinery Sales and Service France SAS. It was developed by Hitachi as a compact alternative to larger models, and the sliding arm extends the working range of the ZX135US-6 considerably to a maximum digging depth of 7,790 mm (25 ft).

Also on show was the new telescopic arm excavator for complex below-ground projects. The smallest model in the range, the ZX210LC-6 is capable of excavating to depths of 21 m (68 ft).

The telescopic arm of the ZX210LC-6 extends and retracts smoothly in seconds using a technologically advanced combination of rope and hydraulic cylinders. This enables it to remove soil quickly and easily from a maximum depth of 21 metres and load trucks efficiently so the material can be transported off site. It is not only more efficient than traditional methods, such as using cranes, skips and conveyor belts, but it is also safer and more cost-effective.
