Cat 320B vs 320C: Which Used Excavator is Better for You?
When it comes to used Caterpillar excavators, the Cat 320B and Cat 320C are two of the most reliable and widely used models in the world. Both offer strong performance and durability, but depending on your work environment and maintenance conditions, one may suit your needs better than the other.
In this article, we’ll compare the Cat 320B vs 320C — focusing on engine, weight, controls, cooling system, and most importantly, why Cat 320B is especially popular in Africa.
1. Technical Specifications
Feature | Cat 320B | Cat 320C |
---|---|---|
Engine | Cat 3066T | Cat 3066T |
Operating Weight | 19,400 kg | 21,760 kg |
Power Output | 138 HP (approx. 103 kW) | 138 HP (approx. 103 kW) |
Max Digging Depth | ~6.6 meters | ~6.7 meters |
Cooling System | Standard radiator | Radiator + intercooler (small or large) |
Control System | Manual hydraulic controls | Advanced electronic controls |
Production Years | 1996–2002 | 2002–2006 |
Both machines use the same powerful Cat 3066T turbocharged engine, but the 320C includes upgrades in electronics and cooling, which come with added complexity.
2. Why Cat 320B Is Preferred in Africa
In many parts of Africa, customers prefer the Cat 320B for one clear reason: it’s easier to repair and maintain.
-
The 320B features a more manual hydraulic system with fewer electronics, making it more reliable in remote or low-tech environments.
-
Local mechanics are more familiar with the B-series, and spare parts are easier to find.
-
In regions with limited access to diagnostic tools or Caterpillar service centers, the 320B can be repaired quickly without expensive equipment.
Verdict:
If you’re operating in Africa or any area with basic repair facilities, Cat 320B is the more practical and cost-effective choice.
3. Performance & Operation
The Cat 320B is known for its simple, mechanical controls. Operators who prefer traditional levers and straightforward operation appreciate the 320B’s intuitive feel and dependable hydraulics.
The Cat 320C, by contrast, offers more refined electronic controls and hydraulics, giving better precision, speed, and operator comfort — but at the cost of greater system complexity.
Verdict:
-
For straightforward, rugged operation: go with the 320B.
-
For smoother, more modern performance: choose the 320C.
4. Cooling System & Fuel Efficiency
While both machines share the same engine, the Cat 320C adds an intercooler (available in large or small size) alongside the radiator, improving cooling efficiency, especially in high-temperature regions or during long shifts.
This leads to better fuel combustion, thermal stability, and longer engine life under constant heavy use.
Verdict:
-
320B is suitable for standard workloads.
-
320C performs better in hot climates or long-hour operations thanks to its upgraded cooling system.
5. Maintenance & Repair
-
Cat 320B: Fewer electronics, more mechanical. Easier to maintain with local tools. Cheaper parts.
-
Cat 320C: More electronics and sensors. May need professional diagnostics. Longer-lasting, but more costly to service.
In African markets, where access to advanced service may be limited, the Cat 320B is often preferred for its ease of repair and field-service friendliness.
6. Resale Value
Both models hold good value in the second-hand market. However, the Cat 320C, being newer and more efficient, often commands a higher resale price, especially when the intercooler system is intact and functioning well.
That said, the 320B remains in high demand in Africa due to its serviceability and lower maintenance costs.
Final Comparison Table
Criteria | Cat 320B | Cat 320C |
---|---|---|
Engine | Cat 3066T | Cat 3066T |
Cooling | Standard radiator | Radiator + intercooler |
Controls | Manual | Electronic |
Maintenance | Easy, low-cost | Complex, higher cost |
Best for | Remote & low-tech environments | High-efficiency, precision jobs |
Popularity in Africa | Very High | Moderate |
Resale Value (Global) | Good | Higher (in some regions) |
