The R 9400 follows the Liebherr design philosophy of maximizing a machines performance by improving the efficiency of all individual subsystems. Engineered for easy serviceability the machine is designed to ensure maximum uptime. The R 9400s spacious cab creates a comfortable working environment, ensuring peak operator performance at every shif.

Built for maximum profitability

• Electro-hydraulic system efficiency

Liebherr hydraulic technology in combination with the precision of electronic control contributes to the R 9400s efficient use of energy. The high-pressure hydraulic system and the optimized pipe and hose layout maximize usable power transmission. 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.

• Independent cooling system

Oil and water cooling fans are independent and electronically managed. The on-demand cooling control provides efficient power for the working process. This technology

contributes to maintaining sustainable temperature of all hydraulic components, extending their life. Closed loop swing circuit All Liebherr mining excavators are equipped with a closed loop swing circuit. Kinetic energy can be saved when the swing motion is used during deceleration, to drive the main and auxiliary pumps, reducing fuel consumption.

• Comfortable cab for efficient work

The large and spacious cab provides ideal working conditions and optimal operators comfort. Mounted on silent blocks, the cab design reduces vibrations and limits noise

pollution to provide a quiet working environment. 

• Extended components lifetime

The R 9400s hydraulic oil filtration systems remove fluid contaminants to offer the highest rate of hydraulic components durability. To maintain oil quality, all return hydraulic oil flow goes through a fine filtration system (15/5 m) and oil tank is sized to considerably extend the time between service intervals.
