Choosing the right excavator shapes your entire mining operation in Latin America. Both the Komatsu PC300-8 and Volvo EC360B target the 30–36-ton segment. However, they excel under very different conditions. Contractors in Chile, Peru, and Bolivia face a real fork in the road. Should they prioritize high-altitude fuel efficiency, or maximize bulk tonnage output? This guide delivers a direct answer for Andes mining teams.
Direct Answer for Andes Mining Contractors (Chile, Peru & Bolivia)
For mines above 3,500m, the Komatsu PC300-8 wins on fuel economy and agility. Its factory ECU compensation limits altitude power loss to under 8%. Therefore, it suits operations that value low diesel burn and fast relocation across narrow mountain benches.
For heavy copper overburden stripping, the Volvo EC360B dominates. Its 37,200 kg frame and 2.0 m³ HARDOX bucket deliver roughly 15% more bulk output per hour. Consequently, high-tonnage double-shift operations benefit most from the Volvo.

Technical Specification Matrix: PC300-8 vs. EC360B
| Specification | Komatsu PC300-8 | Volvo EC360B |
|---|---|---|
| Operating Weight | 31,500 kg | 37,200 kg |
| Engine | SAA6D114E | Volvo D12D |
| Net Power | 187 kW | 198 kW |
| Displacement | 8.27 L | 12.1 L |
| Peak Torque | ~1,200 N·m | 1,475 N·m @ 1,400 RPM |
| Bucket Capacity (Mining) | 1.4–1.6 m³ | 1.9–2.1 m³ |
| Swing Speed | 10.0 rpm | 8.5 rpm |
| Transport Width | 3,190 mm | 3,340 mm |
The Volvo outweighs the Komatsu by nearly 6 tons. Furthermore, that structural ballast directly prevents chassis tipping during hard andesite rock penetration. For full technical breakdowns, visit the Komatsu PC300 specs guide before finalizing your order.
Andes High Altitude (3,500m–4,500m): De-rating vs. Dust Isolation
Komatsu PC300-8: ECU Oxygen Compensation
The PC300-8 carries a mature high-pressure common-rail system. Its ECU automatically adjusts injection timing as altitude increases. As a result, the engine avoids black smoke and keeps thermal de-rating below 8% — the lowest figure in its class. Moreover, the 10.0 rpm swing speed lets operators pivot quickly on tight Andes terraces.

Volvo EC360B: 12.1L Displacement and Care Cab Pressurization
The EC360B takes a different approach entirely. Its massive 12.1-liter displacement generates 1,475 N·m of peak torque at just 1,400 RPM. Therefore, it compensates for thin air through raw displacement rather than electronic trimming alone. Additionally, the sealed Care Cab uses positive-pressure multi-stage filtration. It blocks silica dust and copper particles from reaching operators during 12-hour shifts. This directly protects worker health and reduces fatigue-related errors.

Copper Overburden Loading Cycles & Fuel Burn
In heavy mining cycles, the PC300-8 burns approximately 20.5 L/hr. Meanwhile, the larger EC360B consumes around 25.0 L/hr. Across 2,500 annual mining hours, the Komatsu saves roughly 11,250 liters of diesel. That translates to $10,000–12,000 in annual fuel savings.
However, the EC360B loads 0.5 m³ more per bucket swing. Consequently, it completes truck-loading cycles faster on wider benches. Teams serving operations in Antofagasta and Arequipa should weigh fuel savings against output rates carefully.

Final Procurement Checklist
Choose the Komatsu PC300-8 when:
- Your mine sits above 3,500m elevation
- Diesel transport costs are high and fuel efficiency matters most
- You relocate equipment frequently across narrow mountain roads
- You need fast access to local spare parts and filters in Chile or Peru
Choose the Volvo EC360B when:
- Your site uses pre-blasted rock for continuous high-volume loading
- Double shifts require maximum operator comfort and dust protection
- You run a dedicated maintenance team capable of managing precision fuel systems
- Per-shift bucket output is your primary KPI
FAQ
Q1: Which machine performs better at extreme high altitudes above 3,500m?
— The Komatsu PC300-8 holds a clear edge in combustion efficiency at altitude. Its factory ECU compensation restricts power loss to under 8% with no black smoke. Nevertheless, the Volvo EC360B compensates through its massive 12.1-liter displacement, maintaining strong low-RPM torque even in thin air.
Q2: How does the 6-ton weight difference affect copper overburden stripping?
— The Volvo EC360B weighs roughly 37,200 kg versus 31,500 kg for the Komatsu. That extra structural ballast prevents chassis tipping during hard andesite rock penetration. Furthermore, the larger 2.0 m³ rock bucket yields approximately 15% higher bulk output per hour.
Q3: What is the annual fuel cost difference between these two machines?
— In heavy mining cycles, the Komatsu burns about 20.5 L/hr while the Volvo uses about 25.0 L/hr. Over 2,500 annual hours, the Komatsu saves roughly 11,250 liters. That equals approximately $10,000–12,000 in fuel savings per year.
Q4: Why do Chilean and Peruvian operators value the Volvo Care Cab so highly?
— The Care Cab delivers positive air pressurization and multi-stage dust filtration. It effectively blocks toxic silica and copper dust from entering the cabin. Additionally, silicone hydraulic dampening cushions operators against harsh chassis vibration during intensive 12-hour shifts.
Q5: What is the typical secondary market price gap in Latin America?
— At mid-life condition (5,000–6,500 hours), a used Komatsu PC300 typically trades between $52,000 and $68,000. Meanwhile, a used Volvo EC360B commands $58,000 to $76,000, reflecting its heavier tonnage class and larger bucket capacity.
