Product Description
Engineered for demanding excavation operations, this 2016 XCMG XE490DK delivers exceptional performance through advanced hydraulic architecture and robust powertrain integration. At its core, the QSM11 engine generates 280 kW at 2000 rpm, paired with dual plunger pumps supplying 2×360 L/min flow capacity. This hydraulic configuration provides 301 kN bucket digging force and 248 kN arm digging force, enabling efficient material handling across construction and mining applications.
Operating at 49 tons with a working weight range of 48,100-49,500 kg, this machine combines substantial mass with precision control. The 6,670 mm boom and 2,900 mm arm deliver a maximum digging reach of 10,855 mm and depth capability to 7,000 mm. Bucket capacity ranges from 2.3-3.1 m³, optimized for high-volume excavation cycles.
Technical advantages include:
- 34.3 MPa travel circuit and 31 MPa swing circuit for responsive operation
- 9.2 rpm rotation speed with 70% gradeability
- 725 L fuel tank and 430 L hydraulic reservoir for extended runtime
- 85 kPa ground pressure minimizing surface disturbance
Currently located in Huizhou, Guangdong, this Chinese-manufactured excavator represents proven
