Product Description
Built to endure the demands of large-scale excavation, this 2017 Hitachi ZX300-5A stands as proof that quality engineering holds up over time. Sourced from Fujian, China, this 30-ton workhorse carries a proven track record backed by Isuzu's GH-6HK1XKSA-02 engine — delivering 171 kW at 1,900 rpm with a peak torque of 1,014 N·m. Years of reliable performance in the field speak louder than specs alone.
Designed for heavy-duty backhoe operations, the ZX300-5A offers a 1.4–1.62 m³ bucket capacity, a bucket digging force of 202 kN, and a maximum digging depth of 7,300 mm — giving operators the reach and power needed for demanding excavation cycles. Dual variable axial piston pumps push up to 2 × 236 L/min, keeping hydraulic response sharp and consistent across long working hours.
