Overview
The R 9350 G6 is a 300‑tonne class mining hydraulic excavator designed for high uptime and site productivity. Its simple, field-proven design and ground‑accessible service flap enable fast, safe maintenance. Large bucket/shovel capacities combined with fast cycle times deliver up to 30% higher productivity compared with machines in the same class.

Key highlights

• Reliability: Proven in extreme conditions with millions of operating hours and a simplified design for dependable field performance.
• Productivity: Higher bucket/shovel capacities and fast cycle times — up to 30% more productive than comparable machines.
• Maintainability: Ground-accessible service flap and wide access points for quick, safe maintenance.

E-Drive: zero-emission solution
The optional R 9350 E electric-drive version replaces the diesel drivetrain with electric motors to eliminate local exhaust emissions while maintaining class-leading cycle times.

• No greenhouse gas emissions on job site
• Lower maintenance costs
• Reduced noise emissions
