4. Analysis of key purchasing indicators
1.Chain link hardness: It is recommended to choose the HRC38-42 range. If it is too hard, it will be brittle and if it is too soft, it will wear quickly.
2.Pin fit: The gap of high-quality products is controlled at 0.2-0.3mm, which can reduce abnormal wear and tear.
3.sealing system: The double-lip seal structure is 60% more effective in dustproofing than the traditional single seal.
4.weight balance: The chain weight error per meter should be ≤1.5kg to avoid track deviation.
5. User actual measurement data report
| test items | Brand A | Brand B | C brand |
|---|---|---|---|
| 500h wear amount (mm) | 1.2 | 2.3 | 0.8 |
| Impact resistance test (times) | 2800 | 1900 | 3500 |
| mud permeability | 12% | 25% | 8% |
| Low temperature adaptability | -15℃ | -10℃ | -25℃ |
6. Expert advice
1. Priority selection zone for mining operationsManganese steel reinforcementChain, lifespan is 40% longer than ordinary models
2. Rainy areas should be consideredFully enclosed lubrication system, can reduce sediment invasion by 70%
3. New typeSelf-cleaning gullet designWork efficiency increased by 35% under clay working conditions
4. It is recommended to inspect every 200 working hoursTension, the deviation exceeds 15mm and needs to be adjusted immediately
7. Maintenance tips
• Clean the gravel and debris in the track compartment every week
• Replenish special grease every 50 hours
• Avoid bearing weight on one side when parking
• If the crack in the chain link exceeds 3mm, it must be replaced.
Through the above structured data analysis, I believe you have a clear understanding of how to choose a high-quality excavator chain. It is recommended to choose mature products that have been proven by the market based on actual working conditions and budget.
