Engineering Breakdown And Specifications Of LiuGong Heavy Duty Excavators

 


LiuGong Machinery combines decades of international joint-venture manufacturing experience to produce durable, field-tested earthmoving solutions. The LiuGong 922F crawler excavator represents a pinnacle of modern Chinese engineering, integrating globally sourced tier-one components with heavy-duty structural frames. Designed specifically for demanding contracting fleets, municipal utility departments, and quarry operations, this machine excels in harsh environments requiring high operational uptime.

LiuGong 922F Core Technical Specifications

  • Operating Weight: 22,000 kilograms (48,500 lbs) providing an exceptionally rigid working platform for heavy digging tasks.

  • Engine Model: Cummins B6.7 electronic control diesel engine rated at 129 kW (173 horsepower) meeting stringent global emissions standards.

  • Standard Bucket Capacity: 1.0 to 1.2 cubic meters configured with heavy-duty rock teeth.

  • Max Digging Reach: 9,850 millimeters, ensuring wide grading spans and efficient truck positioning.

  • Max Digging Depth: 6,550 millimeters for deep foundation cuts and utility trenching.

  • Arm Digging Force: 105 kilonewtons, delivering sustained ripping power through dense sub-soils.

  • Track Shoe Width: 600 millimeters standard triple grouser shoes providing low ground pressure of 43.5 kilopascals.

Advanced electro-hydraulic load-sensing controls allow operators to fine-tune working modes ranging from heavy-duty mass excavation to delicate fine grading. The Intelligent Power Control (IPC) system coordinates engine output with hydraulic demand to eliminate stalling under heavy shock loads. Maintenance accessibility is a major asset: wide-opening Gull-wing engine side doors provide ground-level access to fuel filters, engine oil filters, and fluid check points. The ROPS-compliant cab features automatic climate control, adjustable wrist-rest consoles, and a high-definition backup camera system.
