Shopping for a used 20-ton excavator? The Sany SY215 vs CAT 320 debate comes up often among buyers. Both machines sit in the same weight class and handle similar work. However, they serve very different buyers. This guide compares specs, fuel economy, price, and resale so you can make a confident decision.
Sany SY215 vs CAT 320 at a Glance
The table below covers the key specs side by side.
| Feature | Sany SY215C | CAT 320 |
|---|---|---|
| Operating weight | ~21,500 kg | ~20,000–22,000 kg |
| Engine power | ~112 kW | ~103–116 kW |
| Bucket capacity | 0.93 m³ | 0.90–1.19 m³ |
| Max dig depth | ~6.63 m | ~6.69 m |
| New price (approx.) | $120,000–$150,000 | $200,000–$250,000 |
On paper, the two machines are remarkably close. The real differences show up in ownership costs, support, and resale.
Specs & Performance
The Sany SY215C runs a Cummins or Isuzu engine producing around 112 kW. Its maximum dig depth reaches 6.63 m. The swing speed sits at approximately 11 rpm. These numbers are competitive for any 20-ton machine.
The CAT 320 uses a CAT C4.4 ACERT engine rated at 103–116 kW, depending on the model year. Its dig depth is nearly identical at 6.69 m. CAT’s hydraulic calibration is consistent and well-refined across generations. For most digging tasks, both excavators deliver similar raw output. Neither machine gives up much to the other in pure performance.
Fuel & Hydraulics
Fuel economy matters on any long-running jobsite. The Sany SY215C typically burns 10–13 litres per hour in mixed-cycle work. The CAT 320 runs at around 11–14 litres per hour under similar conditions.
Sany’s load-sensing hydraulic system is responsive and effective. However, CAT’s system adapts more smoothly under varying loads. For sustained heavy digging cycles, CAT’s hydraulics feel more consistent. For lighter or mixed work, both machines are closely matched. If your operation runs demanding cycles for long shifts, the CAT 320 shows its edge in hydraulic control.
Price & Resale
This is where the Sany SY215 vs CAT 320 comparison becomes most important for buyers. A new Sany SY215C costs roughly 40–50% less than a new CAT 320. That is a significant upfront saving for any budget-conscious buyer.
However, used CAT 320 excavators hold their value much better. A well-maintained 2018 CAT 320 can sell for 55–65% of its original price. A Sany SY215C from the same year typically retains 35–45%. If you plan to sell within five years, CAT returns more at resale. In markets where CAT financing and dealer networks are strong, used units also move faster.
Parts & Aftermarket Support
CAT’s global parts network covers more than 180 countries. Dealer support, warranty programs, and fast parts shipping are consistently available worldwide. For high-uptime operations, this matters enormously.
Sany’s aftermarket support is growing quickly. In China, Southeast Asia, and parts of Africa, Sany dealer coverage has improved significantly. Independent parts suppliers are also expanding. However, in North America, Europe, and Australia, parts lead times can still be longer than expected.
If you work remotely or need guaranteed uptime, CAT has a clear advantage. If you operate close to an established Sany dealer, the gap narrows considerably.
Which Should You Buy?
The right choice depends on your priorities.
Choose the Sany SY215C if:
- Budget is your primary concern
- You operate in Asia, Africa, or Southeast Asia
- You have reliable access to a local Sany dealer
- You plan to keep the machine for many years rather than resell quickly
Choose the CAT 320 if:
- Resale value is important to your business
- You need parts availability in any region of the world
- Your projects demand high uptime with fast dealer response
- You are based in North America, Europe, or Australia
In the Sany SY215 vs CAT 320 match-up, neither machine is a poor choice. They are simply built for different buyers with different priorities.
