HT90 Large Excavator Overview

The HT90 stands as the heaviest and most powerful model in China’s complete excavator product lineup. With an operating weight of 9000 kg (9 tons), this machine represents true heavy-duty capability for demanding construction projects requiring maximum productivity and raw digging power.

Powered by a robust Kangming QSF2.8 diesel engine certified to Tier 3 / Stage III emission standards, delivering 53 kW (approximately 72 HP) at 2200 RPM through its 4-cylinder direct-injection architecture. This proven powerplant provides ample torque reserve for heavy earthmoving tasks while maintaining competitive fuel economy.

The hydraulic system operates at a professional-grade 27.5 MPa system pressure, generating an impressive 58 kN bucket breakout force and 40 kN arm crowd force. With a 0.4 m3 bucket capacity and a 7050 mm maximum digging height (over 7 meters), the HT90 excels at high-side truck loading, deep foundation excavation, large-scale land grading, and heavy-duty construction applications where smaller machines simply cannot deliver the required output.
