Product Description
Built for heavy-duty excavation, this 2012 Hyundai R305LC-7 delivers 30-ton performance with proven Cummins C8.3-C power. Rated at 190 kW, the water-cooled 6-cylinder engine drives dual variable axial piston pumps producing 2×260 l/min flow for responsive hydraulics across digging, grading, and demolition tasks. Maximum digging depth reaches 7,500 mm with 10,820 mm operating radius, while bucket digging force of 192.2 kN tackles compact soil and fractured rock efficiently.
- Working weight: 29,400 kg with 1.38 m³ backhoe bucket capacity
- Boom/arm configuration: 6,250 mm / 3,050 mm for versatile reach
- Travel speed: 3.1–5.2 km/h with 70% gradeability (35°)
- Hydraulic system: 330 MPa working circuit, 480 L fuel tank for extended shifts
- Transport dimensions: 10,560 × 3,200 × 3,290 mm
- Currently located in Qingdao, Shandong
Equipped with full cab protection and 500 mm ground clearance, this machine handles site conditions from foundation excavation to utility trenching. Hydraulic tank holds 210 L with 320 L total system capacity for sustained operation. Ready for immediate deployment on your next project.
