Power system: Isuzu original 6WG1 engine, power 310kw, sufficient power reserve
Hydraulic system: Kawasaki fully electronically controlled main valve and main pump, the main pump displacement is upgraded from 212cc to 240cc, and the main valve core with 36 large bore is used to reduce the pressure loss of the system
SCR technical route: through the urea supply system to produce a chemical reaction to NOX, reduce NOX emissions, and through the precise control of intake and exhaust gas and fuel injection, the cylinder body is fully combusted, PM particulate matter is reduced, and fuel consumption is reduced
AOCT self-optimizing control system: according to different working conditions, all gear modes work in the best fuel consumption area of the engine
Bucket upgrade: standard 3.2m³ large bucket, can be equipped with 3.8m³ super large bucket, the structure of the wear-resistant plate is upgraded, and 4 kinds of serialized buckets can be configured
C12 cab: intelligent networking, intelligent interaction, intelligent construction, intelligent driving and intelligent maintenance, upgrading intelligent system and display, air conditioning optimization, etc
