The XCMG XE490DK is a high – performance crawler excavator designed for heavy – duty applications. Powered by a Cummins engine, it offers a robust 280 kW (380.69 hp) of power. With a large – displacement main pump paired with XCMG’s proprietary low – speed and high – torque engine technology, the machine responds quickly, ensuring both high – efficiency operation and excellent fuel economy. It also features XCMG’s dedicated “full independent cooling technology” and a high – power radiator, consuming less fan energy and being suitable for high – temperature environments up to 50 °C.



This excavator showcases remarkable design details. The working device has been enhanced for durability, with the use of a new – type rock bucket that comes with additional bucket teeth, a protective lip, and side reinforcement plates, significantly improving its impact – resistance and wear – resistance. As a result, the overall service life of the working device is extended by 20%. The cab is ergonomically designed, providing operators with a spacious and comfortable working environment. It is equipped with a six – point – supported silicone shock absorber to minimize vibration and noise, reducing operator fatigue during long – term operation. Safety features such as a fence – type front – window guard and a FOPS top guard further ensure the operator’s well – being.

In terms of application versatility, the XE490DK is highly adaptable. It is especially well – suited for mining and large – scale construction projects. Different combinations of booms, arms, and buckets allow it to handle a wide range of working conditions. The multi – functional intelligent work tool control system can meet various operation requirements, whether it’s digging, breaking, or dismantling. Additionally, its instantaneous pressurization function enables it to effectively deal with complex and challenging work scenarios, making it an ideal choice for demanding projects.
