Product Description
Built for serious earthmoving operations, the 2022 XCMG XE550DK is a 55-ton hydraulic excavator sourced directly from Gansu, China — ready for immediate deployment on demanding job sites worldwide. Powered by a Perkins 2206 III N six-cylinder engine producing 309.5 kW at 2,100 rpm with peak torque of 1,896 N·m, this machine delivers consistent, high-output performance across heavy digging cycles.
From the operator's seat, the XE550DK is engineered for control and confidence. The spacious cab provides wide sightlines over the work area, reducing fatigue on long shifts. With a bucket digging force of 330 kN and rod digging force of 255 kN, operators can push through tough material without fighting the controls. The dual main pumps deliver 2×360 L/min, ensuring smooth, responsive hydraulic reaction during simultaneous functions.
