Product Description
Built on precision Japanese engineering, the Kato HD512R delivers 12-ton class performance driven by a Mitsubishi 4D34-TLE2A turbocharged, intercooled engine producing 68 kW at 2,050 RPM and a peak torque of 360 N·m at 1,600 RPM. Water-cooled and direct-injected, this 3.91L four-cylinder powerplant is engineered for consistent output across demanding excavation cycles.
At the core of its hydraulic architecture sits a dual variable piston pump system delivering 2 × 121 L/min, with main overflow pressure rated at 29.4 MPa standard and 32.9 MPa in high-power mode — ensuring precise, responsive bucket control across varying load conditions.
