XE270DK hydraulic excavator is a modified product of XCMG\'s DK series, 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.
1. Ecological and economical
* Cummins engine with low fuel consumption, low emission can provide strong power.
* High pressure common rail system improve combustion efficiency.
* With optimized engine power curves and low speed large torque output.
2. Multiple applications
* Different boom and bucket combinations maximize utilization of different conditions.
* Multi-functional machine system meets various job requirements such as digging and crushing.
3. Comfortable operating experience
* Air Conditioner and Heator and multi-channel stereo air input system ensure the appropriate temperature.
* Equipped with advanced audio system.
* The cab equipped with hydraulic shock absorbers has multi-directional and multi-level adjustment functions.
