4R 996 B
Productivity
The R 996 B is built to outperform all competitors in the 600 t class mining market. As a perfect loader for 220 t class dump trucks and above, the R 996 B is the right match for the Liebherr T 264. Developed as the optimal loading tool for large scale mining operations, the R 996 B can achieve the most challenging targets.
Engineered for Intense Mining
Powerful Drive System
Optimized Cycle Times
Easy Machine Control
The R 996 B is equipped with two V16 Cummins engines specifically designed to withstand the most extreme environments. Set for minimum downtime and to boast a 36 m³ / 47.1 yd³ bucket, R 996 B’s drive system allows to reach the highest uptime performance for maximum productivity.
Rather than using open hydraulic circuit, the R 996 B 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.
R 996 B’s electronic machine control Litronic Plus contributes to fast loading cycles and easy control, even if multiple movements are required at the same time.
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, the R 996 B’s attachment ensures the highest forces, easy bucket penetration and high fill factor to perform even in the most demanding conditions.
The R 996 B’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.

Service Intervals
Liebherr hydraulic technology in combination with the precision of electronic control contributes to the R 996 B‘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.
Liebherr’s large dimensioned cooling system reduces fan power consumption and ensures an ideal machine temperature. The hydrostatic fans operate always on the required level for optimal hydraulic oil cooling efficiency.
The R 996 B’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.
Modern Cab for Efficient Work
