When it comes to mid-size hydraulic excavators, the Komatsu PC200-7 stands as one of the most iconic and widely deployed machines in the global construction and mining sectors. Renowned for its legendary durability, fuel-efficient direct-injection engine, and low operating costs, this 7th-generation workhorse has earned its reputation as the "backbone of job sites" across Asia, Africa, and the Americas.
Whether you're a fleet manager, equipment owner, or parts procurement specialist, understanding the Komatsu excavator model nomenclature, technical specifications, and proper maintenance intervals is critical for maximizing uptime and reducing total cost of ownership.
In this comprehensive guide, we prepare everything you need to know about the Komatsu PC series: the PC200-7, PC210-7, and PC220-7— from basic structure to the complete 5,000-hour maintenance schedule.
Part 1: Decoding the Komatsu PC Model Nomenclature
Every Komatsu model number follows a systematic naming convention that reveals key specifications at a glance. Let's decode the "PC200-7" designation:
| Component | Meaning | Details for PC200-7 |
|---|---|---|
| PC | Power Shovel Crawler | Hydraulic crawler excavator (backhoe configuration as standard) |
| 200 | Weight Class (tons ÷ 10) | 20-ton class excavator — actual operating weight: ~19,300 kg |
| -7 | Generation / Series | 7th generation model, launched in 2002 (overseas) / 2003 (China) |
Common Variants You'll See:
- PC200LC-7: Long & Wide Crawler — extended undercarriage for better stability on soft ground
- PC200R-7: Short Radius — compact tail swing for tight urban job sites
- PC210-7 / PC220-7: Heavier weight class variants within the same 7th-gen platform
Backhoe vs. Front Shovel: What's the Difference?
- Backhoe (Standard): The bucket faces downward and toward the machine — ideal for digging trenches, foundations, and loading trucks from ground level. This is the most common configuration for the PC200-7.
- Front Shovel: The bucket faces upward and away from the machine — designed for loading material from a bench or pile into haul trucks, typically used in mining and large earthmoving projects.
Part 2: Full Technical Specifications — PC200-7 vs. PC210-7 vs. PC220-7
The Komatsu PC-7 series shares the same robust GALEO hydraulic platform but is offered in three weight classes to match different job site requirements. Below is a side-by-side comparison of the core specifications:
Operating Dimensions & Performance
| Specification | Unit | PC200-7 | PC210-7 | PC220-7 |
|---|---|---|---|---|
| Bucket Capacity | m³ | 0.8 | 0.9 | 1.0 |
| Operating Weight | kg | 19,300 | 19,500 | 22,700 |
| Max. Digging Depth | mm | 5,980 | 5,980 | 6,010 |
| Max. Digging Height | mm | 7,110 | 7,110 | 7,035 |
| Swing Speed | rpm | 12.4 | 12.4 | 11.7 |
| Travel Speed (Low/Mid/High) | km/h | 3.0 / 4.1 / 5.5 | 3.0 / 4.1 / 5.5 | 3.1 / 4.2 / 5.5 |
| Overall Length (Transport) | mm | 9,425 | 9,425 | 9,885 |
| Overall Width | mm | 2,800 | 2,800 | 2,980 |
Engine Specifications — SAA6D102E-2 Series
The heart of the PC200-7 is Komatsu's legendary SAA6D102E-2 direct-injection diesel engine — widely praised by operators for its tolerance of variable fuel quality and low repair costs.
| Parameter | PC200-7 / PC210-7 | PC220-7 |
|---|---|---|
| Engine Model | SAA6D102E-2-C | SAA6D102E-2-C |
| Engine Type | 4-stroke inline water-cooled direct injection | Same |
| Displacement | 5.883 L | 5.883 L |
| Flywheel Power | 106.7 kW @2000rpm | 125 kW @2000rpm |
Key Engine Advantage: Unlike later -8 electronic injection models, PC200-7 mechanical direct injection engine accepts low-quality diesel fuel, greatly reducing fuel cost and repair difficulty for remote construction sites.
