4R 9400
Productivity
The R 9400 is built to outperform all competitors in the medium class mining market. Boasting a 22,00 m³ / 28.8 yd³ bucket capacity in standard configuration, the R 9400 is the ideal machine to load a fleet of 135 t dump trucks. Available in both diesel or electric versions, the R 9400 offers the flexibility to perform many specific applications.
Engineered for Intense Mining
Powerful Drive System
Optimized Cycle Times
Precise Machine
Motions
The R 9400 is equipped with a Cummins diesel engine which has been specifically adapted to withstand the most extreme environments and to reach the highest uptime performance for maximum productivity. The electric drive system provides superior performance when the machine is used in the most specific conditions.
Rather than using open hydraulic circuit, the R 9400 employs a closed-loop swing circuit to enable maximum swing torque while retaining the full oil flow for the working circuit. The independent swing circuit in combination with the powerful drive system leads to fast arm motion, which contributes to faster cycle times.
The R 9400 design integrates the Litronic Plus electronic control system to allow for easy control even when simultaneous movements are required. The patented Liebherr electronic damping system provides controlled end-cushioning for smooth attachment motions.
High Digging and Lifting Capabilities
High Digging Forces
Power-Oriented
Energy Management
Designed for the best mechanical force distribution, the production-tailored attachment delivers high digging and lifting forces. Integrating Liebherr-made cylinders and a wide range of buckets with mining-optimized GET, the R 9400’s attachment ensures the highest forces, easy bucket penetration and high fill factor to perform even in the most demanding conditions.
The R 9400’s attachment is equipped with the pressureless boom down function to enable fast cylinder retraction without the need for pump energy. Intelligent energy management diverts the pump flow during boom lowering, allowing other cylinder motions to operate unimpeded.
Electronic Cylinder Damping
System
•Patented system based on electronic control
•Controlled end-cushioning for smooth attachment motions
•Allows the operator to focus on loading
•Intelligent energy management by energy saving
•Increase of cylinders reliability
Liebherr Ground Engaging Tools (GET)
Liebherr has developed a complete mining GET solution to complement Liebherr’s mining backhoe and face shovel bucket design. A synergy that enables easy material penetration while extending the life of the bucket.
•Three tooth profiles and five tooth sizes
•Innovative bucket lip and side wall protection
•One single locking system that limits tooling to one unique extraction tool
•Unique hammerless locking system
•Effortless and quick tooth removal

Intervals
Liebherr hydraulic technology in combination with the precision of electronic control contributes to the R 9400’s energy optimization. The high-pressure hydraulic system and the optimized pipe and hose layout maximize usable power transmission. The hydraulic pumps are electronically managed to provide optimal pressure compensation and oil flow management. The hydraulic system is independently regulated over the engine circuit for the best operational efficiency.
The oversized independent oiland water coolers in combination with low energy consumption fans and on-demand cooling controls enable to maximize available power for digging process.
The R 9400’s high pressure hydraulic oil filtration systems remove contaminants from the fluid to offer the highest rate of hydraulic system efficiency. To maintain the oil quality, all return hydraulic oil flow goes through a 15/5 μm fine filtration system. To promote availability, the grease and fuel tanks are sized to considerably extend the time between service intervals.
Comfortable Cab for Efficient Work
Superior Operator
Comfort
The large and spacious cab which equips the R 9400 offers ideal working conditions and optimal operator’s comfort. Mounted on silent blocks, the cab design reduces vibrations and limit noise pollution to provide a quiet environment.
Working Environment
Total Control
The R 9400’s cab offers a panoramic view over the entire attachment and loading spot. Two outside cameras show areas that cannot be observed directly. Long-distance halogen working lights promote efficient loading.
