Why is the excavator powerless?
Recently, the discussion about the powerlessness of excavators has become a hot topic in the field of construction machinery. Many users have reported that the excavator has problems such as insufficient power and reduced work efficiency during use. This article will combine the hot content of the entire network in the past 10 days, analyze the common reasons for the inability of the excavator, and provide structured data to help users quickly locate the problem.
1. Common causes of excavator failure

According to recent discussions among netizens and analysis by experts, the reasons for the inability of the excavator are mainly concentrated in the following aspects:
| Cause classification | Specific performance | solution |
|---|---|---|
| Hydraulic system problems | Insufficient or contaminated hydraulic oil, wear of hydraulic pump, clogged valves | Replace hydraulic oil, clean or replace hydraulic pump, clean valves |
| engine failure | Poor fuel quality, clogged air filter, turbocharger failure | Change fuel, clean or replace filters, and inspect turbochargers |
| Improper operation | Overloaded work for a long time, the operating lever is not fully pushed into place | Avoid overloaded work and standardize operating actions |
| mechanical wear | Tracks are too tight, bearings are damaged, transmission system failure | Adjust track tightness, replace bearings, and overhaul the transmission system |
2. Analysis of recent popular cases
The following are cases of excavator inability that have been discussed frequently by netizens in the past 10 days:
| Case description | Cause of problem | Solution |
|---|---|---|
| The excavator suddenly becomes weak when working on a slope | The oil level in the hydraulic oil tank is too low, causing difficulty in oil suction. | Replenish hydraulic oil to standard oil level |
| New excavator loses power after one week of use | Fuel filter clogged | Replace fuel filter |
| The excavator starts normally when it is cold, but fails after it is warmed up. | Hydraulic oil viscosity decreases due to high temperature | Replace high temperature resistant hydraulic oil |
3. Suggestions on preventing excavator failure
1.Regular maintenance: Replace wearing parts such as hydraulic oil and filters according to the maintenance intervals recommended by the manufacturer.
2.Standardized operations: Avoid long-term overload operation and pay attention to the push and pull strength of the operating lever.
3.daily inspection: Check the oil level, filter status and other key components before work every day.
4.Use genuine accessories: Use hydraulic oil and filters recommended by the manufacturer and avoid using inferior products.
5.Timely maintenance: When abnormal conditions are discovered, the machine should be shut down immediately for inspection to prevent small problems from developing into major failures.
4. Expert opinions
Engineering machinery expert Li Gong said: "The weather has turned cold recently, and many cases of excavator failure are related to changes in the viscosity of hydraulic oil. It is recommended that users replace hydraulic oil suitable for low-temperature environments in winter and appropriately extend the warm-up time."
Maintenance technician Master Wang reminded: "Many problems that appear to be engine weakness are actually caused by hydraulic system failures. It is recommended that users do not blindly replace engine parts and should first check the hydraulic system."
5. Summary
Excavator powerlessness is a common problem that affects work efficiency. Through the analysis of this article, it can be seen that most of the problems of excavator weakness can be avoided through standardized maintenance and operation. When a problem occurs, it should be investigated step by step in the order of hydraulic system, engine, and operating mode. Understanding these common causes and solutions can help users quickly restore device performance and improve work efficiency.
Finally, we remind all excavator users that if they encounter problems that cannot be solved by themselves, they should contact professional maintenance personnel in time to avoid greater losses caused by improper operation.
