922F Excavator Reliability & Performance
Engine Power & Hydraulic Efficiency
The 922f excavator stands out in the f-series excavators lineup for its advanced engine and hydraulic systems. Both the Weidemax and liugong 922fe excavator models use a Cummins engine, which delivers strong net power and ensures high efficiency in heavy-duty applications. The Cummins B6.7 engine in the Weidemax 922F provides 116 kW of net power, supporting demanding construction tasks with ease.
The hydraulic system is a core strength of the f-series excavators. The liugong 922fe excavator features two variable displacement piston pumps, each with a maximum flow of 2x60 GPM. The system operates at 4975 psi in normal mode and can reach 5410 psi in power boost mode. The slew circuit pressure is 4,000 psi, which allows for precise control and smooth operation. The dynamic hydraulic control and smart cooling system help reduce downtime and maintain reliable performance during prolonged workloads.
Key hydraulic features include:
• Intelligent hydraulic system for responsive control
• Dynamic hydraulic control for consistent performance
• Smart cooling system to prevent overheating
• Integrated tools such as payload weighing and camera systems
• User-friendly interface for easy operation
• Precise control in confined spaces
• Enhanced productivity and reduced operator fatigue
The f-series excavators are designed for high operating efficiency and low oil consumption. These features contribute to lower operating cost and less frequent maintenance, making them ideal for projects that require both power and efficiency.
Track Record & Engineering Quality
The f-series excavators have a proven track record in the field. The liugong 922fe excavator and Weidemax 922F both offer impressive operational capabilities, including strong breakout forces, fast travel speed, and quick swing speed. These specifications ensure high performance and productivity on any job site.
| Specification | LiuGong 922F | Weidemax 922F |
|---|---|---|
| Maximum travel speed (High) | 5.6 km/h | 5.6 km/h |
| Maximum travel speed (Low) | 3.3 km/h | 3.3 km/h |
| Maximum swing speed | 10.5 rpm | 10.5 rpm |
| Arm breakout force | 140 kN | 140 kN |
| Arm breakout force Power boost | 152.5 kN | 152.5 kN |
| Bucket breakout force | 89.8 kN | 89.8 kN |
| Bucket breakout force Power boost | 105 kN | 105 kN |
The chart below highlights the travel speed, swing speed, and breakout force for the Weidemax 936E, another member of the f-series excavators, showing the consistent high performance across the product line:
The design of the f-series excavators emphasizes reliability and durability. Every weld undergoes 100% flaw detection, and the boom and arm are engineered using finite element analysis. This process reduces stress by 35% and ensures the structural integrity of the machine. The X-shaped undercarriage and deeper side beams provide extra impact resistance, supporting the excavator in the most demanding environments.
The liugong 922fe excavator also features Feed Forward control technology, which improves control accuracy and responsiveness. This technology, combined with state-of-the-art ergonomic controls, allows operators to achieve high operating efficiency and maintain low oil consumption throughout the workday.
Note: The f-series excavators are built for high efficiency, low oil consumption, and easy maintenance. These qualities help contractors reduce downtime and operating cost while maximizing productivity.
The f-series excavators deliver consistent performance, reliable control, and high efficiency. Their advanced hydraulic systems, strong engine power, and robust design make them a top choice for heavy-duty construction projects.
