Komatsu PC200-8 vs Caterpillar 320D — Which Excavator Is the Better Choice for Your Project?

By Sam from Dige International Trading

In the 20-ton excavator category, the Komatsu PC200-8 and the Caterpillar 320D are two of the most widely used machines around the world. Contractors across Africa, the Middle East, and South America rely on them for construction, roadwork, and general earthmoving tasks.

But which one should you choose? This comparison breaks down performance, fuel consumption, maintenance, parts availability, and long-term value.

Engine Performance & Hydraulics

Komatsu PC200-8

• Known for smooth, precise hydraulic control

• Excellent for finishing work and fine trenching

• Very stable during long hours of digging

• Komatsu’s hydraulic tuning gives it one of the best “operator feel” responses in the 20-ton class

Caterpillar 320D

• Strong low-end torque from the CAT C6.4 engine

• Fast cycle times, ideal for high-productivity jobs

• Powerful boom and arm force for tough soils

• Great for loading trucks and heavy digging

Verdict:

PC200-8 = better precision and smooth control

320D = better power and faster digging cycles

Fuel Efficiency

One of the biggest differences between the two machines is fuel consumption.

PC200-8 Advantages:

• One of the most fuel-efficient excavators in the industry

• Komatsu’s “ECO” mode reduces consumption without losing too much productivity

• Popular in regions where fuel cost is high (Sudan, Kenya, Peru, Vietnam)

320D Fuel Characteristics:

• Slightly higher consumption due to stronger power output

• Still efficient, but not as economical as Komatsu in long continuous operation

Verdict:

If fuel savings are important → PC200-8 wins

Maintenance & Parts Availability

PC200-8

• Easy to maintain with straightforward systems

• Parts are widely available in Asia, Africa, and the Middle East

• Electronics are stable and not overly complicated

• Undercarriage parts cost less compared to CAT

320D

• Strong dealer support globally, especially in Africa and Latin America

• Higher parts price but excellent quality

• Easy to source filters, seals, pumps, and engine components

Verdict:

PC200-8 = cheaper parts

320D = stronger global dealer network

Durability & Working Conditions

PC200-8 Strengths:

• Very reliable in heat and dusty climates

• Ideal for road construction, land clearing, and long work cycles

320D Strengths:

• Better in extremely hard soil, rock, and heavy-duty digging

• Stronger structural components

• Superior resale value in most countries

Verdict:

PC200-8 = stability and long working hours

320D = strength and high resale value
