Product overview
The Liebherr R 9600 G8 is a 600-tonne class mining excavator designed for high payload per pass, long service intervals and field upgradeability. The modular architecture enables life-cycle upgrades. Liebherr Power Efficiency (LPE) management reduces fuel consumption by up to 20% versus the predecessor model while optimising hydraulic efficiency and component lifetime.

R 9600 highlights

• Designed service life: > 80,000 operating hours (modular design enables upgrades)
• Class-leading payload: ~7% more payload per pass
• Fuel savings: up to 20% less fuel consumption vs predecessor (LPE)

Main versions & options

• Standard powertrain: 2x Cummins QSK 50
• Optional powertrain: 2x Liebherr D9812
• Electric / E‑Drive option available for on‑site zero‑emission operation
• Attachment variants: backhoe (backhoe configuration) and face shovel (front shovel) with multiple bucket options

Liebherr Power Efficiency (LPE) – advantages

• Up to 20% reduced fuel consumption through integrated engine and hydraulic management
• Maximised hydraulic efficiency and reduced throttling
