LIEBHERR R920 COMPACT CRAWLER EXCAVATOR

Technical Description

The Liebherr R 920 Compact is a versatile crawler excavator designed for high performance in confined spaces, offering an operating weight of approximately 42,880 lbs (19,450 kg). It is powered by a robust 150 hp (112 kW) engine compliant with Stage V emission standards, delivering reliable net power at 1,800 RPM and torque of 682 Nm at 1,400 RPM. The machine features a mono boom measuring 5.0 meters paired with a 2.65-meter stick, enabling a maximum digging depth of 19 ft (5.8 m) and a maximum reach along the ground of 29.3 ft (8.9 m). Its compact design allows a tight tail radius of around 1,850 mm, ensuring excellent maneuverability on construction sites with limited space. Equipped with the Liebherr Synchron-Comfort system (LSC), the excavator incorporates electronic engine speed regulation, pressure and flow compensation, and mode selection for optimized hydraulic and engine performance tailored to specific tasks—from fuel-efficient operation to maximum digging power. The cooling system integrates water, hydraulic oil, and charge air coolers with a thermostatically controlled fan, maintaining optimal operating temperatures. The undercarriage uses a robust X-frame design with a standard gauge width of 2,250 mm and maintenance-free track components, supporting a maximum travel speed of 5.7 km/h in high gear. The hydraulic system provides a flow of up to 300 l/min at 350 bar, ensuring smooth and powerful implement control. The spacious, air-conditioned cab features an air-sprung seat with suspension, a completely retractable front window, and a 7-inch high-resolution touchscreen for easy operation and monitoring. Bucket capacities range from 0.30 to 0.95 m³, making the R 920 Compact suitable for a broad range of excavation and earthmoving applications.
