Product Description
Engineered for precision in confined job sites, the Hyundai R55-7 mini excavator delivers serious hydraulic performance within a compact 5,500 kg working weight. Powered by a Yanmar 4TNV94L water-cooled, 4-cylinder engine producing 40 kW at 2,200 rpm with a 3.054-liter displacement, this machine balances fuel efficiency with consistent output across demanding excavation cycles. Dual variable axial piston pumps with a combined maximum flow of 2 × 55 l/min drive a robust hydraulic circuit rated at 220 MPa for travel and 180 MPa for rotation — specifications that define reliable digging force under sustained load.
