Product Description
Engineered for large-scale excavation projects, this 2021 XCMG XE550DK delivers 55-ton performance through precision hydraulics and robust powertrain architecture. At its core, the Perkins 2206 III N engine generates 309.5 kW at 2100 rpm with 1896 N·m maximum torque, paired with dual main pumps flowing 2×360 L/min for responsive control under demanding conditions. Operating weight of 51,200 kg combines with 88 kPa ground pressure to maintain stability across varied terrain while minimizing surface impact.
Technical highlights include:
- 330 kN bucket digging force and 255 kN arm force for efficient material handling
- 6,550 mm boom and 2,550 mm arm configuration optimized for reach and breakout power
- 9.2 rpm swing speed with 3,800 mm rear turning radius for confined site maneuverability
- 725 L fuel capacity and 430 L hydraulic reservoir supporting extended operational cycles
- 600 mm track plates on 2,740 mm gauge providing superior traction and load distribution
Currently located in Jincheng, Shanxi, this Chinese-manufactured excavator represents XCMG's commitment to heavy-duty reliability in the 50-ton class segment.
