Product Description
Engineered with precision hydraulics and robust power systems, this 2021 XCMG XE155DK excavator delivers 93kW of rated power through its QSF3.8 turbocharged engine. Operating at 2200 rpm with 500 N·m maximum torque, the water-cooled, direct-injection powerplant ensures consistent performance across demanding jobsites. Dual main pumps supply 123.5 L/min each, feeding a working hydraulic circuit rated at 34.3/37 MPa for responsive control and efficient cycle times.
Built on XCMG's proven 15-ton platform, this machine combines a 14,600 kg working weight with exceptional digging capabilities—106.9 kN bucket force and 73.4 kN rod force. The 4,600 mm boom and 2,520 mm arm provide an 8,304 mm maximum reach and 5,535 mm digging depth, while maintaining a compact 7,795 mm transport length. Ground-specific pressure of just 37 kPa minimizes surface disturbance on sensitive terrain.
