Hitachi has developed the ZX135US-6 with a sliding arm mechanism specifically for deep excavation projects in confined spaces. It can dig deeper and has a significantly smaller footprint than a 30-tonne standard model. This makes it the perfect machine for urban and road construction projects, and particularly the installation of pipes for utilities.


Hitachi has utilised its excavator manufacturing expertise to address the need for powerful machines capable of working in confined spaces. The ZX135US-6 with sliding arm has been developed in-house as a compact alternative to larger models, capable of digging further and with a significantly smaller footprint. It will complete excavation tasks quickly and efficiently, enabling projects to be executed safely and on schedule.
