XCMG XE490DK is a 48-ton heavy-duty hydraulic crawler excavator, purpose-built for high-intensity mining and earthmoving operations. It is powered by a Cummins QSM11 engine with rated power of 280 kW at 2000 rpm, delivering strong low-speed torque. The machine integrates advanced hydraulic systems, reinforced structures, and intelligent control technologies to balance high efficiency, durability, and fuel economy.
Equipped with a customized Cummins engine featuring a low-speed high-torque curve for robust heavy-load output. Advanced hydraulic technologies like flow regeneration and load-adaptive control reduce energy loss and fuel consumption. The crushing self-optimization system cuts fuel use by over 20% while maintaining efficiency.
Key structural components are CAE-optimized with large castings and variable cross-sections for superior bending and torsion resistance. The reinforced undercarriage and H-type working device withstand harsh mining conditions. Larger swing bearings enhance load capacity and extend service life.
Intelligent control systems automatically match engine and hydraulic power to different working conditions. Altitude-adaptive technology ensures stable performance in high-altitude areas. A multifunctional tool control system supports digging, breaking, and other attachments.
A three-stage oil pre-filter air intake system adapts to dusty mining environments. Optimized cooling systems enable operation in up to 50°C ambient temperatures. Service points are easily accessible, reducing downtime and maintenance costs.
XCMG XE490DK excels in heavy-duty mining operations, including open-pit excavation, ore loading, and rock breaking. It is ideal for large-scale earthmoving, highway and bridge construction, and foundation engineering projects. The machine also performs well in quarrying, water conservancy projects, and other demanding heavy-duty construction scenarios.
