Crawler excavator R 9150 G7

demolitionfor rockhigh payload

Overview
The R 9150 G7 is a versatile mining excavator in the 150‑tonne class, offered in backhoe, face‑shovel and frontless configurations. Its optimized attachment geometry ensures efficient force distribution for high digging and hoisting performance and maximised bucket fill per cycle. Centralised service areas on the uppercarriage provide fast access to fluid compartments for reduced downtime.

Key highlights

• Configurable for multiple applications: backhoe, face‑shovel or frontless for demolition and special tasks.
• High digging and breakout forces through optimized attachment design for improved cycle payload.
• Central service access for quick maintenance and reduced machine downtime.

R 9150 E‑Drive: zero emission solution
The E‑Drive variant uses electric drive motors to deliver competitive cycle times without local diesel exhaust emissions. Benefits include:

• No on‑site exhaust emissions
• Lower maintenance requirements compared with conventional diesel drivetrains
• Reduced operational noise

Liebherr Power Efficiency (LPE)
LPE engine and hydraulic management optimises power and hydraulic flow to the task, reducing fuel use and improving component life. Benefits include:

• Up to 20% lower fuel consumption
• Improved hydraulic efficiency
• Reduced hydraulic throttling and reduced engine load profile for longer component life
