Product Description

Engineered for heavy-duty excavation, this 2021 XCMG XE550DK delivers exceptional performance through precision-built hydraulics and robust power systems. At its core, a Perkins 2206 III N six-cylinder engine generates 309.5 kW at 2100 rpm, producing 1896 N·m of maximum torque to handle demanding dig cycles. Dual main pumps supply 2×360 L/min flow capacity, translating into 330 kN bucket digging force and 255 kN rod digging force—critical metrics for high-volume earthmoving operations.

Key Technical Specifications:

  • Operating weight: 51,200 kg with 55-ton excavation capacity
  • Boom reach: 6,550 mm; rod length: 2,550 mm
  • Maximum tractive force: 370 kN for superior grading power
  • Ground pressure: 88 kPa minimizes surface disruption
  • Fuel efficiency: 725 L tank with 13 L displacement engine
  • Transport dimensions: 11,870×3,572×4,100 mm

Currently located in Putian, Fujian, this Chinese-manufactured crawler excavator combines proven XCMG engineering with reliable Perkins power for consistent productivity in mining, infrastructure, and large-scale construction environments.
