XE270DK hydraulic excavator is a modified product , which is specially designed for heavy-duty operations in small and medium-sized mines and quarries. Based on "efficient, reliable, intelligent and energy saving", dig down into product performances. Through the program optimization, operation speed is paired with adaptive fuel consumption in all working modes, and fuel consumption will be reduced by 6% without affecting the efficiency. With reinforced boom and arm, standard 1.3m³ rock bucket, and optimized bucket shape, the digging resistance will be decreased and the durability will be doubled.

The whole machine adopts imported 128.5kW high-power engine, featuring low speed and high torque, high-pressure injection, stronger power and better fuel economy. New high-efficiency main pump is fully upgraded, with large displacement, which is 7% higher than that of the previous generation. High efficiency, and leakage is reduced under the same pressure. Swashplate swing angle makes power density increase, and achieves much more work. With new generation of high efficiency main valve, the overflow pressure is increased, the pressure loss is smaller, and the working ability is more outstanding. The new safe operation lever can prevent vehicle movement caused by misuse from causing personal injury, and is more safe and reliable. The latest power matching technology and optimized fuel power curve can save up to 7% fuel. Adopting whole brazing technology and new-type radiator welded by robots, and configuring positive pressure degassing type expansion tank, to improve the pump life, quickly remove the gas within engine and waterway, reduce the rust, and it can meet 50ºC environmental requirements.

The turntable adopts a rigid box structure to provide higher strength and improve the cab shock absorption. The engine mounting base structure is strengthened to improve shock absorption. With main body adopting I-beam rigid structure, the whole machine's strength is intensified, and the turntable side beam adopts the D-tube structure to improve its ability to resist external impact. The main body of the turntable adopts robot welding technology to improve the durability and safety of the structural parts.

The travelling mechanism adopts strengthened key parts of the chain rails bearing stress to improve the strength and impact resistance of the chain rails, and the service life of the track is greatly improved. The butter dish is changed from welding parts to integral stamping parts, which ensures the installation roundness of the sealing ring, prevents the sealing ring from wrinkling and improves the sealing performance. With strengthened X-beam section, and the strength of the end face is greatly improved by increasing the size, thickness and structure of the box beam.

A new generation instrument has an 8-inch large screen display (the largest one among the industry). The page layout is more detailed and the picture is clearer. The new control system uses CAN bus, the monitor is responsible for display, the controller is responsible for signal acquisition and output, and the bus connects with monitor, GPS controller, engine ECM, which can achieve faster data management and more efficient control. With functional attachment control system, you can choose more than ten kinds of attachments including hammer, hydraulic shears and others by clicking one button, and achieve versatile applications with one machine.
