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
The R 996 B is equipped with two V16 Cummins engines specifi cally 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.
Optimized Cycle Times
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 fl ow 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.
Easy Machine Control
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 fi ll 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 fl ow during boom lowering, allowing other cylinder motions to operate unimpeded.
Compact Machine Design
Liebherr’s excavator design is well-balanced and provides best machine stability enabling:
• High weight distribution towards the undercarriage
• Effi cient utilization of the strong digging forces
• Favorable power to weight ratio of the uppercarriage and attachment
• Fast cycle times
High Altitude Kit (Option)
Designed to offer maximum effi ciency and productivity for operation in high altitude:
• Solution integrated in machine structure
• Adapted engine
• Pressurized hydraulic tank
• Can be combined with the Arctic Kit

Effi ciency
The R 996 B follows the Liebherr design philosophy of maximizing the machines performance by improving the effi ciency of all individual subsystems. Engineered for optimum serviceability the machine is designed to ensure maximum uptime. The R 996 B’s spacious cab creates a comfortable working environment ensuring peak operator performance, every shift.
Optimized for Maximum Profi tability
Electro-Hydraulic System Effi ciency
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 fl ow management. The hydraulic system is independently regulated over the engine circuit for the best operational effi ciency.
Cooling System Effi ciency
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 effi ciency.
Optimized Service Intervals
The R 996 B’s high pressure hydraulic oil fi ltration sys­tems remove contaminants from the fl uid to offer the highest rate of hydraulic system effi ciency. To main­tain the oil quality, all return hydraulic oil fl ow goes through a 15/5 μm fi ne fi ltration system. To promote availability, the grease and fuel tanks are sized to con­siderably extend the time between service intervals.
Modern Cab for Effi cient Work
Superior Operator Comfort
Working Environment Total Control
The large and spacious cab which equips the R 996 B 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.
The R 996 B’s cab offers a panoramic view over the en­tire attachment and loading spot. Two outside cameras show areas that cannot be observed directly. Long­distance xenon working lights promote effi cient loading.
Fast Maintenance System
The service fl ap is hydraulically actu­ated and accessible from the ground level allowing for fast maintenance:
• Hydraulic oil refi ll
• Engine oil refi ll and drainage
• Splitterbox and swing gearbox oil exchange
• Attachment/swing ring bearing grease barrel refi lling with fi lters
• Windshield washer water refi lling
• Fast fuel refi lling line
Comfort-Oriented Cab Design
An array of features:
• Tinted laminated safety glass
• Armored front and attachment side windows
• Heavy duty sun louvers on windows
• Adjustable air suspended seat
• A/C with dust fi lter in fresh air / recirculated
• Pressurization to prevent dust penetration
• Trainer seat
