· AOCT self-optimizing control technology is adopted to optimize the hydraulic spool and increase the main pump displacement to achieve fuel economy.
· An extended boom, arm, and a unique control program make the machine more straightforward to achieve long-distance and efficient operation.
· Increase the weight of the counterweight with a longer undercarriage to ensure operation stability.
· Reinforced structural parts cope with complex working conditions; multi-stage reinforced fuel filter system copes with inferior oil products. High-efficiency heat dissipation cooling system and hydraulic pulse absorber are adopted.
