Product Description
Built for demanding excavation work, this 2021 XCMG XE550DK delivers 55-ton performance with operator-centered engineering. Powered by a Perkins 2206 III N engine generating 309.5 kW at 2100 rpm, this machine combines robust hydraulic power with refined control systems. Dual main pumps supply 720 l/min total flow, enabling precise simultaneous operations while maintaining responsive bucket and arm movements.
Operators benefit from exceptional visibility across the 3800 mm rear turning radius, supported by strategically positioned counterweights at 1353 mm ground clearance. The spacious cabin provides clear sightlines to the 6550 mm boom and 2550 mm arm during grading and trenching operations. Stability remains consistent thanks to 88 kPa ground pressure distribution across 600 mm track plates, while the 2740 mm track gauge ensures balanced performance on uneven terrain.
- Bucket digging force: 330 kN for challenging soil conditions
- Working weight: 51,200 kg with optimized load distribution
- 9.2 rpm rotation speed for efficient cycle times
- 725 L fuel capacity supports extended shifts
- Currently located in Anhui, China
