Hitachi Other models

Hitachi's construction-machinery history began in 1949 with the U05, the first mechanical excavator developed entirely with domestic Japanese technology. In 1965 came the UH03, the first fully Japanese-developed hydraulic excavator built without foreign technical assistance. Its two-pump, two-valve system markedly improved control and later became the de facto worldwide standard for such hydraulic systems. In 1991, Hitachi launched five mini-excavator models, deliberately expanding this segment; the ZAXIS UR series later followed, offering an especially tight turning radius for work in confined spaces. Listed in the register: SX604.
