Product Description
Built for demanding excavation work, the Hitachi ZX300-5A delivers proven 30-ton performance with a focus on operator control and long-shift comfort. Powered by an Isuzu 6HK1 engine producing 171 kW at 1,900 rpm and 1,014 N·m of peak torque, this machine handles heavy digging cycles without strain. A bucket digging force of 202 kN and maximum digging depth of 7,300 mm make it well-suited for deep foundation work, trenching, and mass earthmoving operations.
From the cab, operators benefit from the wide-visibility design standard to Hitachi's Generation-5 platform — reduced blind spots, low-vibration controls, and an ergonomic layout built for precision on congested job sites. The 600 mm track plates and 57.8–58 kPa ground pressure keep the machine stable across varied terrain, while a 70% grading ability confirms its competence on slopes.
