Liebherr R 996 B - Manual (Page 5)

5 R 996 B
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
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
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 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.
Power-Oriented
Energy Management 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.
