Product Description

Large Crawler Excavator 49Ton Hydraulic Excavator XE490DK For Sale
 

Product Description

XE490DK large crawler excavator integrates the valuable experience gained from years of research and development of excavating products, and adopts advanced design and manufacturing methods. Meanwhile,XE490DK large crawler excavator adheres to the design concept of "high efficiency, high safety, low carbon and environmental protection".  

I. More energy-saving and environmental protection
* Power system adopts the imported (QSM11), featuring direct injection, four stroke, water-cooling, turbocharger, air to air intercooler, six cylinder engine. XE490DK large crawler excavator adopts efficient HPI fuel injection technology, through separate cylinder control and full electronic control, fuel economy will be greatly increased. It is an engine specifically designed and manufactured for engineering machinery operation conditions.

II. More efficient returns
* XE490DK large crawler excavator adopts customized torque curve, which has the characteristics of low speed and large torque, low fuel consumption, good economy and so on. At the same time, the engine adopts constant power mode in a specific speed segment, which enables the machine to maintain a strong power output under heavy load and low speed.

III. More reliable and durable
* Sturdy travelling mechanism can meet the requirements of heavy-load operations, its durability, reliability and mobility is higher. Equipped with reinforced four rollers and one track, excellent performance and more reliable quality can be achieved. Strengthen the lower frame and X-type beam, improve the strength of cross section, disperse the stress of carbody, it is qualified for more hard work.

IV. More intelligent control
* XEICS system with independent intellectual property rights, using CAN bus communication to achieve the corresponding control function, CAN effectively adapt to the operating environment, operating conditions and operating load, so as to be able to identify, think, judge, make decisions and execute.

V. More comfortable and safe
* The cab with pressurization function can effectively prevent dust from entering the cab and provide a clean working environment for drivers. The internal frame of the cab is strengthened, the overall structure strength is increased, pin holes are added in the front and rear, and safety performance is improved. Cab equipped with double laminated glass, can effectively filter UV and increase high protection level.

VI. Convenient maintenance
* Oil filter, pilot filter, fuel filter, oil and water separator, and air filter are accessible on the ground to check and replace, it is within your reach, easy to maintain, saves maintenance time, and improves work efficiency.
