|---|---|---|
| Caterpillar | CAT 320 | "3" represents the excavator series, "20" represents the tonnage (about 20 tons) |
| Komatsu | PC200-8 | "200" represents 20 tons, "8" represents the 8th generation product |
| Sany Heavy Industry | SY215C | "215" stands for 21.5 tons, and "C" stands for third-generation technology |
2. Ranking of popular excavator models in the past 10 days
According to Baidu Index and WeChat Index data, the following models have the highest search volume recently:
| Ranking | Model | heat index | focus |
|---|---|---|---|
| 1 | CAT 336 | 8,520 | Mining performance |
| 2 | XCMG XE370DK | 6,780 | Advantages of domestically produced large tonnage |
| 3 | SANY SY75C | 5,930 | Market performance of micro-mining |
3. Correlation rules between model numbers and configurations
By comparing mainstream models, we found that there is the following correspondence between the digital part and the core configuration:
| Number field | Corresponding configuration | Example description |
|---|---|---|
| First two/three places | Working weight (tons) | PC200≈20 tons, SY75≈7.5 tons |
| last digit | technology generation | -8 means 8th generation, -5 means 5th generation |
| middle letter | special features | D means extended chassis, K means mine version |
4. The 5 most frequently asked questions by users
Based on discussions on Zhihu and Tieba:
1.Question:How big is the difference between different suffixes (such as -5/-7) of the same model?
Answer:Usually represents an upgrade to engine emission standards, -7 reduces fuel consumption by about 12% compared to -5
2.Question:Why do some model numbers not match actual tonnage?
Answer:Some manufacturers use "nominal tonnage". For example, the actual weight of SY75 is 8.2 tons.
3.Question:How much more expensive is Caterpillar's "E" series than its "D" series?
Answer:The price difference of the same model is about 15-20%, but the fuel efficiency is improved by 30%
4.Question:Why do small excavator models have decimals (such as 1.8 tons)?
Answer:The Japanese system is accustomed to using 0.5 tons as the grading unit, and domestic products are now gradually unified.
5.Question:What do the letters "LC" stand for in the model number?
Answer:Long Crawler (extended track), the grounding specific pressure is reduced by 20-25%
5. Purchase suggestions
Based on current market dynamics, the following suggestions are given:
1.Municipal engineering:Priority is given to the 5-8 ton class (such as SY60C), which is flexible in transition and can meet most working conditions;
2.Mining operations:For models with a "K" suffix above 30 tons (such as XE370DK), pay attention to matching bucket capacity;
3.Rural market:Pay attention to 1.8-3.5 tons microcomputers (such as PC30) and pay attention to the traveling motor configuration.
Through the structured data display and hot spot analysis in this article, I believe you have a clearer understanding of the digital password of the excavator model. It is recommended to make the final selection based on specific working conditions and the latest technical parameters.
