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

Hydraulic System Effi ciency
The R 996 B’s hydraulic system is designed
for an optimized hydraulic power management via the:
• Closed-loop swing circuit
• Pressureless boom down function
• Electronic hydraulic pumps management
• High pressure hydraulic oil fi ltration system
• Electro-hydraulic control system
• Optimized pipe and hose layout

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
