When it comes to medium-sized excavators, two of the most popular models are the Caterpillar CAT 320D and the Komatsu PC200-8. Both machines are trusted worldwide for earthmoving, roadwork, and construction projects. But how do they compare, and which one is the better choice for your business? Let’s break it down.

1. Engine Power and Performance

• CAT 320D is powered by a Cat C6.4 ACERT engine, delivering around 138 kW (185 hp). It offers strong digging force and smooth hydraulic control, making it highly efficient for heavy-duty work.

• Komatsu PC200-8 comes with a Komatsu SAA6D107E-1 engine, producing about 110 kW (148 hp). While slightly lower in horsepower, it is known for reliability and fuel efficiency.

Verdict: CAT 320D provides more horsepower and stronger digging force, ideal for demanding operations. Komatsu 200-8 offers a balance of performance and efficiency, making it suitable for general construction work.

2. Fuel Efficiency

• CAT 320D focuses on productivity, sometimes at the expense of higher fuel consumption. However, its advanced hydraulics help optimize energy use.

• Komatsu PC200-8 features Komatsu’s fuel-saving technology, making it one of the more economical excavators in its class.

Verdict: If fuel cost is a major concern, Komatsu PC200-8 has the edge.

3. Operator Comfort and Technology

• CAT 320D is well-regarded for operator comfort, with spacious cabins, ergonomic controls, and reduced vibration. Advanced monitoring systems improve machine management.

• Komatsu PC200-8 also offers a comfortable cab with low noise levels and easy-to-use controls. It includes Komtrax, Komatsu’s GPS-based tracking system, for real-time monitoring.

Verdict: Both offer modern operator-friendly features, but Komatsu’s Komtrax system provides added fleet management benefits.

4. Durability and Maintenance

• CAT 320D is famous for durability and long service intervals. Caterpillar’s global support network makes parts and service widely available.

• Komatsu PC200-8 is also highly reliable, with strong undercarriage and robust hydraulics. Komatsu’s support is solid, but parts availability can vary depending on the region.

Verdict: Both machines are durable, but CAT’s global parts support gives it a slight advantage.

5. Resale Value

• CAT 320D holds higher resale value in most markets due to strong demand and brand reputation.

• Komatsu PC200-8 also retains good value but generally slightly lower than CAT.

Final Thoughts: Which One to Choose?

• Choose CAT 320D if you need maximum digging power, global support, and higher resale value. It’s ideal for heavy-duty contractors who prioritize productivity.

• Choose Komatsu PC200-8 if you want fuel efficiency, lower operating costs, and reliable performance for medium workloads. It’s a great option for contractors looking to reduce expenses while maintaining solid performance.

Both excavators are excellent choices in the 20-ton class, and the best decision depends on your project requirements, budget, and long-term fleet strategy.
