Why the excavator is powerless: hot topics and in-depth analysis on the Internet in the past 10 days
Recently, the discussion about "excavator powerlessness" has become a hot topic in the field of construction machinery. Combining the data from the entire network in the past 10 days, we have compiled common causes, solutions and industry trends that may cause excavators to become ineffective, helping users quickly locate problems and take countermeasures.
1. Statistics of hot topics on the entire network in the past 10 days
| Ranking | Topic keywords | Search volume (10,000 times) | Main discussion platform |
|---|---|---|---|
| 1 | Excavator cannot be repaired | 12.5 | Baidu, Douyin |
| 2 | Hydraulic system failure | 8.7 | Zhihu, Tieba |
| 3 | Engine power decreases | 6.2 | WeChat, Bilibili |
| 4 | Impact of filter blockage | 4.9 | Kuaishou, Weibo |
2. Five core reasons for the inability of excavators
1.Hydraulic system problems(accounting for 42%)
Hydraulic oil contamination, pump valve wear, or pipeline leakage can lead to insufficient pressure, which manifests as slow and weak movements.
2.Reduced engine performance(accounting for 28%)
Poor fuel quality, clogged fuel injectors or turbocharger failures directly affect power output.
3.Filter element clogged(accounting for 15%)
If the air filter and oil filter element are not replaced for a long time, it will lead to insufficient air intake or poor lubrication.
4.Improper operation(accounting for 10%)
Overloaded operation for a long time or failure to adjust the working mode according to the working conditions.
5.Other mechanical failures(accounting for 5%)
Such as damage to the transmission system, abnormal control circuit, etc.
3. Solution comparison table
| Fault type | Detection method | Solutions | Cost estimate (yuan) |
|---|---|---|---|
| Hydraulic system | Pressure gauge test | Replace hydraulic oil/repair pump valve | 800-5000 |
| engine | Diagnostic instrument reads data | Clean oil line/replace accessories | 1500-8000 |
| Filter element clogged | Visual inspection | Replace the third filter | 300-1000 |
4. Latest industry trends (last 10 days)
1.Smart diagnostic equipment hot-selling: Data from an e-commerce platform shows that sales of portable hydraulic detectors increased by 67% month-on-month.
2.Preventive maintenance gets attention: The Douyin #excavatormaintenance topic has been played more than 120 million times.
3.The rise of new energy excavators: Sany Heavy Industry released a white paper on reducing the failure rate of electric excavators by 30%.
5. Expert advice
1. Perform regular hydraulic oil testing (every 500 hours)
2. Use original filter elements to avoid secondary damage caused by auxiliary parts.
3. Cold areas require the use of low-temperature anti-wear hydraulic oil
