2. 20 Tons Excavator Model Application Comparison Table
| Model | Core Characteristics / Market Positioning | Suitable Working Conditions | Considerations / Relative Weaknesses |
| Caterpilar 320D | Robust, Durable, High Resale Value. Classic American design. Powerful, excellent reliability, a hard asset in the used market. | Mining, heavy earthworks, harsh conditions. Ideal for challenging, high-intensity environments. | Relatively higher fuel consumption, higher purchase and parts cost, operator comfort and smoothness not its primary focus. |
| Komatsu PC200-8 | Fuel-Efficient, Eco-Friendly, Long-Lasting. Japanese benchmark. Renowned for exceptional fuel economy and long service life. | General earthmoving, municipal projects, rental fleets. Ideal for buyers focused on long-term operating costs. | High purchase price, less “heavy-duty” than CAT in extreme conditions, relatively conservative in adopting new technologies. |
| Hitachi ZX200 | Fast & Smooth, Efficiency-Focused. Known as the “King of Quarries.” Fast compound movements, short cycle times, precise control. | Truck loading, trenching, grading. Excellent for earthmoving projects where efficiency is paramount. | Requires high-quality maintenance; some models may have specific minor issues; needs careful upkeep. |
| Volvo EC200 | Safe, Comfortable, Intelligent. European representative. Top-tier ergonomic cab, focuses on operator experience and safety features. | Municipal construction, roadwork, long operating hours. Ideal for sites valuing operator comfort and environmental standards. | High purchase cost, more complex electrical/hydraulic systems, higher technical repair threshold and part costs. |
| Doosan DX225 | Cost-Effective, Economical & Practical. Leading Korean brand. Competitive pricing, durable, low total cost of ownership. | General earthmoving, infrastructure, agriculture. Suitable for budget-conscious buyers seeking reliable output. | Brand prestige and resale value slightly lower than CAT/Komatsu; some minor gaps in fit/finish and materials. |
| Hyundai 220LC-9S | Well-Equipped, Affordable. Similar positioning to Doosan. Offers good specifications and attractive pricing. | General earthmoving, infrastructure, rental. Direct competitor to Doosan, widely applicable. | Similar to Doosan, slight gap in brand recognition and ultimate durability compared to traditional leaders. |
| Sany SY215 | Domestic Leader, High Cost-Performance. Top Chinese brand. High specifications (often with Cummins engine), significant price advantage. | General earthmoving, rural construction, budget-sensitive projects. Readily available domestic parts, low repair costs. | Long-term reliability and resale value still lag behind top international brands, but the gap is narrowing. |
