Electro-Hydraulic System Efficiency

Liebherr hydraulic technology in combination with the precision of electronic control contributes to the R 9250s 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.

Cooling System Efficiency

The oversized independent oil- and water coolers in combination with low energy consumption fans and ondemand cooling controls enable to maximize available power for digging process.

Optimized Service Intervals

The hydraulic oil filtration systems remove fluid contaminants to offer the highest rate of hydraulic components durability. To maintain oil quality and extend oil lifetime, all return hydraulic oil flow goes through a fine filtration system (15/5 m). To promote availability, the grease and fuel tanks are sized to considerably extend the time between service intervals.

Superior Operator Comfort

The large and spacious cab which equips the R 9250 offers ideal working conditions and optimal operators 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 9250s cab offers a panoramic view over the entire machine and loading spot. Two outside cameras show areas that cannot be observed directly. Long-distance halogen working lights promote efficient loading.
