The XCMG XE550DK is a 55-ton class heavy-duty crawler excavator manufactured by XCMG, China's premier construction machinery producer. This model features a reinforced large undercarriage and high-power travel reducers specifically designed for demanding mining operations. Powered by a Perkins 2206ⅢN engine delivering 309.5 kW at 2,100 rpm with National III emission compliance, it operates at a total weight of 52,500 kg with a bucket capacity of 2.5-3.5 cubic meters.
1.Powerful and Efficient PerformanceThe Perkins 2206ⅢN 6-cylinder engine generates 309.5 kW with 1,896 N·m torque for heavy-duty mining operations. Its 12.5-liter displacement delivers low-speed high-torque characteristics for efficient penetration. The water-cooled, turbocharged design ensures reliable performance in rigorous working conditions.
2.Durable Heavy-Duty StructureReinforced box-frame chassis with thickened plates ensures exceptional bending and torsional resistance in mining environments. Large undercarriage with adjustable gauge and powerful travel reducers provide stability and strong traction. High-strength materials and accurate welding technology extend service life under continuous heavy loads.
3.Comfortable and Safe OperationThe spacious ROPS-certified cab features ergonomic controls and adjustable suspension seating for operator comfort. Intelligent monitoring system with LCD display integrates machine status, fault diagnosis, and working hour tracking. Low vibration and noise levels reduce operator fatigue during extended mining shifts.
This excavator excels in large-scale open-pit coal and metal mining operations where heavy-duty performance and reliability are critical. It serves reliably in large earthmoving projects, quarry aggregate production, and major infrastructure development requiring high productivity. The XE550DK is equally capable in road construction, building demolition, and material handling operations with various attachments available, making it a powerful solution for mining contractors and heavy construction fleets worldwide.
