At the same time, it adopts DOC+DPF+SCR post-treatment technology and electric heating of urea pipeline, which not only reduces fuel consumption, but also makes emissions cleaner and more environmentally friendly. The hydraulic system is equipped with a well-known brand of fully electronically controlled main valve and main pump. The displacement of the main pump is increased from 212cc to 240cc, and a 36 large-diameter main valve core is used to reduce system pressure loss, improve efficiency and reduce fuel consumption.

The excavator has outstanding design highlights. The standard 3.2m³ large bucket and optional 3.8m³ super large bucket are available. The bucket adopts wear-resistant blade plate structure, which is suitable for the harsh environment of mines and loading of gravel, granite and other working conditions. In addition, 4 series buckets can be configured to achieve “one bucket for one condition” and improve construction efficiency. The boom and dipper fully apply the 20,000-hour working device technology, the box structure is enlarged and widened, with multiple internal ribs built in, and high-strength materials are selected.
