Product Description
Engineered for maximum productivity, this 2022 XCMG XE550DK delivers 55 tons of excavating power through a robust Perkins 2206 III N engine generating 309.5 kW at 2100 rpm. Twin main pumps supply 2×360 L/min hydraulic flow, driving an impressive 330 kN bucket digging force and 255 kN rod digging force—specifications that translate directly to faster cycle times and reduced operational costs on demanding jobsites.
Built with precision by XCMG's advanced manufacturing facility in China, this crawler excavator combines a 6550 mm boom and 2550 mm rod with intelligent hydraulic distribution for superior reach and control. The 51,200 kg working weight provides exceptional stability, while maintaining just 88 kPa ground pressure to minimize site damage. Perkins power technology ensures reliable performance across extended duty cycles, supported by a 725-liter fuel capacity for all-day operation.
