Cat 320 vs Komatsu PC220 Excavator: Which is Better?

Cat 320 vs Komatsu PC220 Excavator: Which Is Better?

When discussing the Cat 320 vs Komatsu PC220 excavator, it is important to clarify a key fact: these two machines are not in the same weight class. The Cat 320 belongs to the 20-ton class, while the Komatsu PC220 is typically considered a 24 ton excavator.

This means the comparison is not purely equal—it is more of a cross-class comparison, which actually makes it more practical for buyers choosing between flexibility and power.

Understanding the Class Difference

Before diving deeper into the Cat 320 vs Komatsu PC220 excavator comparison, here is a quick breakdown:

• Cat 320: ~20tons
• Komatsu PC220: ~24 tons

In reality:

• Cat 320 competes more directly with Komatsu PC200 / PC210
• Komatsu PC220 is closer to Cat 323 in size and capability

This difference affects performance, fuel consumption, transport, and job suitability.

Performance Comparison

When comparing Cat 320 vs Komatsu PC220 excavator, the size difference directly impacts performance.

• Digging Force:
  Komatsu PC220 has stronger digging force due to its heavier weight and larger components. It performs better in hard soil, rock, and heavy-duty applications.
• Stability:
  The PC220 offers better stability, especially when lifting or working on uneven terrain.
• Speed & Precision:
  Cat 320 provides smoother and faster hydraulic response, making it ideal for precision work and shorter cycle times.

Fuel Efficiency and Operating Cost

A major consideration in the Cat 320 vs Komatsu PC220 excavator decision is cost.
