Extended
The liugong 920f excavator integrates power, precision, and durability into the 20-ton excavator segment. Its Cummins F4.5 engine is custom-tailored for operation in low- and mid-RPM ranges, delivering maximal torque exactly when hydraulic load demands it. This engine, compliant with China IV emissions standards, supports consistent output while optimizing fuel economy during heavy-duty duty cycles.
At the heart of the hydraulic architecture is LiuGong’s electronic positive-flow pump and proportional control valve system. By managing pilot signal-based flow distribution, the system ensures smooth response in attachment, boom, and arm control, even during fast cycle operation. The intelligent cooling system activates as needed, maintaining oil and engine temperatures without continuous fan drag.
Structurally, the 920F features high-tensile steel booms and a robust undercarriage with oversized pins and reinforced linkages. Ground pressure is managed better with 600 mm track shoes, and gradeability of 35° enables the machine to work on embankments or quarry walls.
From a geometrical standpoint, the 920F boasts substantial reach and depth: digging to ~6.7 m with loading heights up to ~7 m and an extended radius of nearly 9.87 m. These specs allow the machine to perform effective pile loading, trench excavation, and stockpile engagement without repositioning.
For operators, the cabin environment is optimized with seating comfort, intuitive controls, a multifunction LCD panel for diagnostics and service alerts, and excellent all-round visibility. Combined, these ensure productivity and safety across long shifts.
Maintenance access is facilitated via grouped filter and fluid access panels at ground level, reducing check and replacement time. The cooling configuration includes an oil cooler and strategically placed electronic fan to minimize heat load without compromising airflow.
The liugong 920f excavator also features quick-attach coupling with optional auxiliary hydraulic connections—ideal for rotating attachments, breakers, augers, and grapples. Its modular design allows rental operations and site managers flexibility across diverse job types.
Supported by LiuGong’s global infrastructure, including regional parts warehouses and authorized technical service centers, the 920F stands as a durable and reliable choice for contractors, public works departments, and rental fleets requiring high output and minimal downtime.
