• Eco Mode Functionality: Lowers engine RPM during light-load conditions, improving fuel economy by 12–15%
• Real-World Efficiency: At 70% duty cycle, fuel consumption averages 210–250 L/day (8-hour shift)

Note: Efficiency improves with operator training and scheduled maintenance (fuel filter, injector calibration, and air intake cleaning).

---

Load Capacity & Bucket Performance

The load capacity of the excavator-bucket system is determined by:

• Bucket Fill Factor: 0.85–0.95 (material-dependent; e.g., loose soil vs. blasted rock)
• Rated Bucket Capacity: 1.5 m³ nominal (GP bucket), 1.2 m³ (rock bucket with wear protection)
• Breakout Force: 160–185 kN (dependent on hydraulic pressure and linkage geometry)
• Payload per Cycle: 2.1–2.8 metric tons (material density: 1.4–1.9 t/m³)

Bucket Type	Capacity (m³)	Avg. Cycle Time (sec)	Tons/Cycle	Daily Output (8 hrs)
General Purpose	1.5	22	2.4	~780 tons

Performance	Blocks H₂O and Cl⁻ ingress; protects up to 90 days at sea
Removal	Biodegradable solvent wash or hot alkaline degreaser (on-site)
Compliance	Meets ISO 9227 (salt spray test ≥500 hrs)

4.3 Application Workflow

1. Surface preparation: Degrease and dry (dew point control: ≤3°C below ambient)
2. Spray application in controlled environment (enclosed warehouse)
3. Secondary protection: VCI (Vapor Corrosion Inhibitor) paper wrap on pivot points
4. Final overpack: UV-resistant polyethylene shrink wrap (optional for Flat Rack)

Mandatory for all export shipments – non-compliance voids warranty on surface integrity.

---
