Cat 320D vs Komatsu PC200-8 Excavator: Which Is Better?

When choosing a used 20-ton excavator, two popular models are the Cat 320D and Komatsu PC200-8. Both are well-known Japanese-market machines with strong performance, good durability, and a large global parts market.

But which one is better for construction, earthmoving, road work, and mining applications?

In this Cat 320D vs Komatsu PC200-8 Excavator comparison, we will look at performance, engine, fuel efficiency, maintenance, durability, operator comfort, and resale value.

Cat 320D vs Komatsu PC200-8: Basic Comparison

The Cat 320D is a 20-ton-class excavator from Caterpillar, while the Komatsu PC200-8 is a similar-size excavator from Komatsu.

Both machines are designed for general construction, excavation, loading, road construction, and other heavy-duty applications.

Specifications can vary depending on production year, configuration, region, and optional equipment, so buyers should always check the exact machine serial number and specification sheet.

Engine and Performance

The Cat 320D is commonly equipped with the Caterpillar C6.4 ACERT engine. It provides strong power and is designed for demanding excavation and loading work.

The Cat 320D has a reputation for strong digging performance, especially when working in hard soil, construction sites, and quarry applications.

The Komatsu PC200-8 uses the Komatsu SAA6D107E engine on many configurations. It is known for reliable performance and good fuel economy.

For normal excavation work, both machines have enough power for most 20-ton-class applications.

If your priority is strong digging and heavy-duty working performance, the Cat 320D has an advantage. If fuel consumption is a major concern, the PC200-8 is also a very strong choice.

Fuel Consumption

Fuel consumption is particularly important when buying a used excavator because fuel can represent a large part of operating costs.

The Komatsu PC200-8 is generally regarded as a fuel-efficient machine. Its engine and hydraulic system were designed to provide good performance while controlling fuel consumption.

The Cat 320D also offers reasonable fuel efficiency, although actual consumption depends heavily on working conditions, operator habits, engine condition, hydraulic condition, and attachment.

For buyers working long hours every day, the PC200-8 may have an advantage in fuel economy.

However, the difference between two used machines can be more important than the difference between the models themselves. A well-maintained Cat 320D can consume less fuel than a poorly maintained PC200-8.

Hydraulic System and Digging Ability

Hydraulic performance is one of the most important factors when comparing excavators.

The Cat 320D provides strong hydraulic performance and good digging force. It is particularly suitable for heavy excavation, loading, trenching, and working in harder ground.

The PC200-8 also has a strong hydraulic system and offers smooth operation and good control.

For general earthmoving, the two machines are quite close.

For customers who frequently use hydraulic breakers or work in harder ground, the condition of the hydraulic pump, main control valve, cylinders, and hydraulic lines should be checked carefully before purchase.

Reliability and Durability

Both Caterpillar and Komatsu have strong reputations for producing durable construction equipment.

A properly maintained Cat 320D can work for many years. Caterpillar machines are also popular in many developing markets because mechanics are familiar with the brand and replacement parts are relatively easy to find.

The Komatsu PC200-8 is also known for its reliability. Many PC200-8 machines have been used for thousands of working hours while continuing to perform well when properly maintained.

For a used excavator, however, maintenance history is more important than the brand name alone.

Before buying either model, check:

• Engine condition
• Hydraulic pump performance
• Final drives
• Swing motor
• Boom and arm
• Hydraulic cylinders
• Undercarriage
• Cooling system
• Electrical system
• Hour meter and operating history

A clean, well-maintained machine with higher hours can be a better purchase than a low-hour machine with poor maintenance.

Maintenance and Spare Parts

This is an important advantage for both models.

Caterpillar and Komatsu are widely used around the world, so parts and technical knowledge are available in many countries.

The Cat 320D has excellent aftermarket and original-parts support. Mechanics in many African and Asian markets are familiar with Caterpillar excavators.

The Komatsu PC200-8 also has a strong parts network and is widely supported by local repair shops.

For African buyers, both models can be relatively easy to maintain compared with less common excavator brands.

Operator Comfort

The PC200-8 offers a comfortable cab with good visibility and relatively smooth control.

The Cat 320D also provides a practical operator environment and good visibility for excavation work.

Cab condition is especially important when buying used equipment. A machine may have excellent mechanical performance but still require significant investment if the cab, air conditioning, seat, monitor, or controls are damaged.

When inspecting a used excavator, test all cab functions rather than judging the machine only by its appearance.

Undercarriage Condition

The undercarriage can have a major effect on the real value of a used excavator.

Tracks, rollers, idlers, sprockets, track chains, and related components can be expensive to replace.

Therefore, when comparing a Cat 320D with a PC200-8, don’t simply ask which model is better. Compare the actual undercarriage condition.

For example, a Cat 320D with an 80% undercarriage may be a better deal than a PC200-8 with a 30% undercarriage, even if the Komatsu has a lower purchase price.

Used Excavator Price

Used prices vary significantly depending on year, working hours, country of origin, condition, configuration, and maintenance history.

Older Cat 320D and Komatsu PC200-8 excavators can sometimes have attractive prices in the used market.

Caterpillar machines often maintain strong resale demand because of the Caterpillar brand and their popularity in many construction markets.

Komatsu PC200-8 machines are also highly popular and can offer excellent value for buyers looking for a balance between purchase price, fuel consumption, and performance.

When buying from China, compare the FOB price, machine condition, working hours, undercarriage condition, and shipping cost instead of choosing a machine based only on the advertised price.

Cat 320D vs Komatsu PC200-8: Which Is Better?

So, which machine should you buy?

The answer depends on your application.

Choose the Cat 320D if:

• You want strong digging performance.
• You frequently work in hard soil or demanding conditions.
• Caterpillar machines are popular in your local market.
• You want strong resale demand.
• Local mechanics are more familiar with Caterpillar.

Choose the Komatsu PC200-8 if:

• Fuel efficiency is a major priority.
• You want smooth hydraulic operation.
• You need a reliable general-purpose excavator.
• Komatsu parts and mechanics are easily available in your market.
• You find a PC200-8 with better overall condition and price.

Final Verdict

The Cat 320D vs Komatsu PC200-8 Excavator comparison is quite close because both are proven 20-ton-class machines.

The Cat 320D is a great choice for buyers who prioritize digging power, durability, brand reputation, and resale value.

The Komatsu PC200-8 is an excellent option for buyers who prioritize fuel efficiency, smooth operation, reliability, and overall operating cost.

For used equipment buyers, however, the condition of the individual machine is more important than choosing between Caterpillar and Komatsu.

If you are buying a used excavator for Africa or another overseas market, compare the engine, hydraulic system, undercarriage, working hours, maintenance history, and final price before making your decision.
