Komatsu offers a wide variety of excavator models, which may make you unsure which model and tonnage to choose. Below is a comparison of Komatsu excavator sizes and which model is best suited for your work.
Komatsu excavators come in three size categories: mini (1–10 tons), medium (10–30 tons), and large (30–100+ tons). Each type is designed for different projects. Mini models are ideal for tight areas, medium ones suit general construction, and large excavators serve heavy-duty jobs like mining and major earthworks.
Let’s explore Komatsu excavator sizes and how to choose wisely.
What Are the Sizes of Komatsu Excavators?
Komatsu offers a complete lineup of excavators to suit various jobsite needs. From backyard digging to open-pit mining, their models are categorized by weight, digging depth, and horsepower. This section gives you a comprehensive overview of each category in the Komatsu excavator sizes chart, including practical use cases.
Mini Komatsu Excavators (1–10 tons)
These compact excavators are lightweight, agile, and ideal for urban environments or landscaping projects. Weighing under 10 tons, they offer powerful performance in a small footprint.
Mini Komatsu excavators like the PC30MR-5 and PC55MR-5 are excellent for tight-access spaces. Their low operating weight reduces ground pressure, making them perfect for indoor demolitions, gardens, or roadside utilities.
Contractors love these machines for their ease of transport, low fuel consumption, and surprisingly strong digging capabilities. If you’re working in tight quarters or residential zones, this is your category.

|---|---|---|---|---|---|
| PC30MR-5 | 24.4 hp | 9 ft 1 in | 189 in | 6,812 lbs | 6,800 |
| PC35MR-5 | 24.4 hp | 11 ft 2 in | 207 in | 7,993 lbs | 7,200 |

Medium Komatsu Excavators (10–30 tons)
Medium-sized models are the most versatile in Komatsu’s lineup. Balancing power and maneuverability, they’re ideal for general construction, utility work, and road building.
Popular models like PC138USLC-11 or PC210LC-11 fall within this range, offering extended reach and more lifting power than mini units. With operating weights between 20,000 to 60,000 lbs, these machines tackle a wide range of civil and commercial tasks.
Medium excavators are commonly used by road crews, foundation contractors, and municipal works departments. They offer comfort, reliability, and excellent return on investment.

Large Komatsu Excavators (30–100+ tons)
Large excavators are built for power and endurance. These beasts are frequently seen in mining sites, ports, and massive infrastructure projects.
The PC360LC-11 and PC8000-11 are built to handle the most demanding applications. Weighing from 70,000 to over 1.7 million pounds, they offer extreme digging force and unmatched hydraulic strength.
Operators appreciate their stability, advanced control systems, and high fuel efficiency despite the size. If you’re moving hundreds of tons of material per day, you’ll want one of these giants.
| Excavator Model | Horsepower | Max Dig Depth | Max Reach (inches) | Operating Weight (pounds) | Bucket Digging Force (lbf) |
|---|---|---|---|---|---|
| PC360LC-11 | 257 hp | 24 ft 1 in | 380 in | 80,000 lbs | 35,200 |

What Are The Features Of Komatsu Excavators?
Komatsu machines are known for durability, fuel economy, and smart tech. From intuitive joystick controls to hybrid engine options, each excavator blends power with precision. Models often feature load-sensing hydraulics, auto idle shutdown, GPS-based guidance, and customizable digging modes.
Most Komatsu models include Komtrax—Komatsu’s telematics system that allows remote monitoring and diagnostics. These features reduce downtime, improve job planning, and help lower operational costs.
Whether new or used, Komatsu machines are designed for long-term reliability. This makes them a top choice in many komatsu excavator sizes for sale listings globally.
How to Choose the Right Size Komatsu Excavator?
Choosing the right machine depends on your job scope, terrain, and transportation logistics. Mini excavators are easy to trailer and use less fuel. Medium ones balance strength with versatility. Large models maximize output for heavy-duty operations.
You should consider dig depth, reach, lift capacity, and total cost of ownership. Also, factor in the space constraints of your site. For urban contractors, a smaller or offset tail-swing model may be ideal.
When in doubt, consult a distributor or exporter like us. We help clients across Africa, the Middle East, and South America choose the perfect unit every day.
Planning to Buy a Used Komatsu Excavator?
