It adopts a newly designed positive pressure cab with novel appearance, com-fortable control, wide feld of vision, full protection as standard, large space andhigh safety. The sealing performance is 70% higher than that of the same leveleffectively isolating dust and significantly reducing noise in the cab; the cab canbe equipped with an anti-falling object protection frame and anti-falling objectprotection equipment, allowing the machine to be operated with confidence inharsh working environments.

New generation main pump, advanced technology, negative flow control, deepadjustment, precise power matching, increased bearing and shaft diametercapacity, improved reliability. Customized debugging of the main valveprovides excellent performance, more coordinated movements of the entiremachine, and higher operating efficiency.

Comprehensively optimize the structure of key parts, strengthen stress-bearingparts, and avoid harsh working conditions; the boom box design increases reli-ability, and the bucket bottom plate, side plates, and reinforcement plates areall made of high-strength wear-resistant materials to improve the bucket's reli-ability and durability.
