1. Weights and Dimensions
• Operating Weight: Typically 30,200 kg (66,580 lb). This can change based on the choice of arm (e.g., mono-arms are more common in this class), track shoe width, and counterweight.
• Transport Dimensions:
◦ Length: 10,690 mm (35 ft 1 in)
◦ Width: 3,190 mm (10 ft 6 in) - With 600mm shoes.
◦ Height: 3,350 mm (11 ft 0 in) - To top of cab.
2. Engine (Power & Emissions)
• Manufacturer & Model: Cummins B6.7
• Emission Standard: Compliant with Tier 4 Final (USA) and Stage V (Europe) regulations. It uses a simple DOC/SCR after-treatment system (with Diesel Exhaust Fluid - DEF/AdBlue), eliminating the need for a complex and maintenance-heavy Diesel Particulate Filter (DPF).
• Net Power: 162 kW (217 hp) @ 2,000 rpm. This provides strong performance for digging and lifting.
3. Hydraulic System
• Pumps: Two variable displacement axial piston pumps provide a high combined flow, ensuring smooth, powerful, and responsive operation.
• Main Relief Valve Pressure: 34.3 MPa (4,974 psi) - This high pressure contributes to the strong digging forces.
• Pilot Pressure: 3.9 MPa (566 psi) - Provides smooth and easy control of the machine.
4. Performance
