· AOCT self-optimizing control technology is adopted to optimize the hydraulic spool and increase the main pump displacement to achieve fuel economy.
· Long boom and arm,special control program make machine easier to achieve long- distance and efficient operation.
· Increase the weight of counterweight, with longer undercarriage, 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, hydraulic pulse absorber.
