Choosing an inappropriate excavator size might result in wasted money and decreased efficiency. Let’s locate the ideal Cat machine for your project.
Caterpillar excavators come in four main size classes: Mini (1–10 tons), Small (10–20 tons), Medium (20–40 tons), and Large (40+ tons). Mini excavators suit tight urban spaces, while large ones handle heavy-duty tasks like mining. Choosing the right size depends on project type, budget, and transport logistics.
Now, let’s dive deeper into Caterpillar excavator sizes, their best-use cases, and model recommendations.
What Sizes Do Cat Excavators Come In?
Caterpillar divides its excavators into four standard sizes according to operating weight and application range.
Mini Excavators (1–10 tons / 2,000–22,000 lbs)
Mini excavators are the most compact machines in the Caterpillar lineup. They are ideal for tight spaces, urban job sites, indoor demolition, and landscaping. These models are lightweight and easy to transport.
Popular models: CAT 301.7, CAT 305.5, CAT 308
Best for: Individual users, small contractors, light-duty tasks
Small Excavators (10–20 tons / 22,000–40,000 lbs)
Small excavators provide more power while still offering good maneuverability. They are commonly used for utility work, small construction projects, and roadside digging.
Popular models: CAT 313, CAT 315, CAT 318
Best for: Urban infrastructure, trenching, contractors needing compact power
Medium Excavators (20–40 tons / 44,000–88,000 lbs)
Medium-sized machines strike a balance between performance and efficiency. They can handle most construction jobs, including foundation work, material loading, and earthmoving.
Popular models: CAT 320D, CAT 323, CAT 330
Best for: General construction firms, subcontractors, multi-use projects
Large Excavators (40+ tons / 90,000+ lbs)
These machines are built for the most demanding tasks, such as mining, road building, and large-scale excavation. They deliver exceptional horsepower, deeper digging, and increased bucket capacity.
Popular models: CAT 336, CAT 349, CAT 395
Best for: Government projects, mining operations, large contractors

|---|---|---|---|---|
| Mini | 1 – 10 tons (2,000–22,000 lbs) | CAT 301.7, CAT 305.5, CAT 308 | Landscaping, small urban projects, indoor use | ✅ CAT 305.5 – for individuals and small contractors |
| Small | 10 – 20 tons (22,000–40,000 lbs) | CAT 313, CAT 315, CAT 318 | Urban construction, roadwork, trenching | ✅ CAT 315 – for tight sites with moderate digging needs |
| Medium | 20 – 40 tons (44,000–88,000 lbs) | CAT 320D, CAT 323, CAT 330 | General construction, foundation, loading work | ✅ CAT 320D – best for multipurpose use |
| Large | 40+ tons (90,000+ lbs) | CAT 336, CAT 349, CAT 395 | Mining, infrastructure, large-scale excavation | ✅ CAT 336 – for large earthmoving projects |
What Is The Difference Between Cat 315 And 317?
Cat 315 and Cat 317 are popular medium-duty machines, but they serve slightly different roles.
The CAT 317 weighs approximately 38,100–40,200 lbs (17–18 tons), while the CAT 315 is slightly smaller. The 317 typically offers more horsepower and deeper digging capability.
For buyers who need more lifting power and versatility—especially on mid-sized job sites—the 317 offers better value. However, the 315 suits smaller urban construction projects or those with limited transportation capacity.
What Is The Difference Between Cat 320 VS 323?
Both the Cat 320 and Cat 323 are widely used excavators, but they differ in size, power, and application.
TheCat 323 weighs approximately24–26 tons, while theCat 320 is slightly smaller, typically ranging from20–22 tons. The 323 generally offers more horsepower, greater digging depth, and higher lifting capacity, making it better suited for heavy-duty tasks.
For contractors needing enhanced performance in large-scale earthmoving or mining operations, the323 provides greater efficiency and productivity. However, the320 remains a strong choice for general construction, roadwork, or projects requiring easier transport and maneuverability. If power and reach are priorities, the 323 is the better investment, while the 320 balances versatility and cost-effectiveness for medium-duty jobs.
What Are The Most Recommended CAT Models For Different Buyers?
At HIOSEN, we’ve exported used Caterpillar excavators for over 14 years, and we recommend specific models for different buyer types:
- Individual buyers or light users: CAT 305.5 (Mini Excavator) – easy to transport, simple operation
- Construction contractors: CAT 320D (Medium Excavator) – versatile, proven performance, good resale
- Heavy-duty users or fleet managers: CAT 336 (Large Excavator) – powerful, fuel-efficient, good for bulk earthmoving
These machines are all available in used condition with full inspection reports, competitive pricing, and fast shipping to Peru, Africa, and the Middle East.
How Do Caterpillar Excavator Sizes Affect Prices and Shipping?
Larger machines are more expensive, both in terms of price and logistics. Shipping a CAT 336 can cost 2-3 times more than shipping a CAT 305.5, particularly to ports in South America or Africa.
We assist customers save money by providing deconstructed shipping, local warehouse partners, and various payment options. Don’t forget that larger excavators may face higher import duties, depending on the country.\
