This mid-to-high power unit perfectly matches the regular load of medium-large factories and large construction sites. Its 704kW standby power provides 10% overload margin for sudden equipment startup. It fully meets daily power demands while helping clients save extra costs on over-sized power equipment.
With 4600 N·m peak torque, it delivers excellent resistance to voltage drop during startup of tower cranes, large pumps and fans. It effectively suppresses transient frequency fluctuation and prevents protection relay tripping, ensuring stable operation of core construction and mining equipment.
The built-in 1200L fuel tank enables 12 hours of continuous operation at 75% load. Ideal for remote mining stations and long-cycle infrastructure projects with unstable fuel supply. It reduces refueling frequency and labor workload, easing operation pressure in harsh off-grid areas.
Equipped with Class H insulated brushless alternator, it keeps total harmonic distortion below 5% and outputs pure sine wave power. It protects PLC systems, industrial robots, banking servers and data center UPS from harmonic interference, avoiding equipment malfunction and data loss.
Adopting Yuchai’s mature inline-six heavy-duty engine platform, it features optimized heat dissipation and reinforced structure, suitable for 24/7 operation in high-temperature and dusty mining & construction sites. The 500-hour standard maintenance cycle cuts annual service frequency and overall lifecycle costs.
