The SH470-9 excavator of Shitian Heavy Industry takes the advanced electro-hydraulic system as the core, realizing the deep integration of electronic control, hydraulic transmission and intelligent decision-making. This system adopts digital closed-loop control technology, with a response time as low as 0.2 seconds, which ensures precise and sensitive operation even in complex working conditions such as high-precision excavation and heavy-load lifting. Compared with the previous SH470-8 model, the efficient coordination of the electro-hydraulic system drives a 12% increase in work efficiency and an 8% year-on-year reduction in fuel consumption, significantly improving operational economy for global customers.

Equipped with the Cummins QSM11 engine, the equipment features reliable performance, high efficiency and low fuel consumption, providing stable and powerful power support for the advanced electro-hydraulic system. Cooperated with the high-efficiency and large-displacement INLINE main pump, it realizes the optimal matching of power output and hydraulic demand, avoiding energy waste while ensuring strong operation capability. The integrated power and electro-hydraulic system makes the excavator excel in heavy-duty operations such as mining and earthmoving.

Benefiting from the intelligent protection function of the advanced electro-hydraulic system, the SH470-9 can automatically monitor the operating status of key components, realize early warning of faults and overload protection, and greatly extend the continuous operation time. The optimized overall structure and high-strength materials further enhance the durability and stability of the equipment. It is widely applicable to mining, road construction, foundation excavation and other complex scenarios, maintaining efficient and stable operation in harsh environments.
