Six Core Product Advantages
Powerful and Reliable Engine Performance
Equipped with original imported Isuzu 6-cylinder heavy-duty engine, it delivers sufficient power reserve and strong low-speed torque. The engine keeps steady operation under continuous heavy load without speed drop. With simple structure and excellent durability, it perfectly adapts to severe mining and quarry working environments.
Superior Heavy-Duty Digging Capacity
The ultra-high bucket digging force matches the optimized H-type reinforced working device. It performs excellently in hard soil, rock excavation and bulk material loading, effectively improving overall construction productivity.
Energy-Saving HIOS IIIB Hydraulic System
The advanced HIOS IIIB hydraulic system realizes precise load sensing control. All compound actions are smooth and coordinated with quick response. It reduces energy loss and cuts fuel consumption by around 12% compared with previous generations.
Fully Reinforced Durable Structure
The whole machine adopts thickened high-strength steel and professional welding technology. Key stress parts including boom, arm, bucket and chassis are strengthened and forged. It effectively resists impact, abrasion and deformation, ensuring long-term stable operation under harsh conditions.
Comfortable and Safe Operating Environment
The spacious fully enclosed cab isolates external noise, dust and vibration. ROPS and FOPS protection structures guarantee operator safety. Humanized layout and high-comfort suspension seat relieve fatigue during long-hour continuous work.
Convenient Maintenance and Global Parts Supply
All daily inspection and maintenance points are designed at ground level for easy access. Extended service intervals reduce routine maintenance frequency. Standard spare parts are widely available worldwide, minimizing equipment downtime and lowering comprehensive operating costs.
