Zaxis-3 and Zaxis-5 models are produced side by side, although the former range is slowly being superseded. There are three types of Zaxis-5 models, with different specifications for China, other parts of Asia, America, Europe and Japan to comply with the emissions regulations for each region.

“Hitachi is currently number three in the industry,” says Ryo Nakajima, Manager of the Assembly Section for medium and large excavators. “However, if we continue to adapt to the new technology that is available from other Hitachi companies, then we can hopefully go on to become the global market leader.”
