What is the reason why the excavator has difficulty walking?
Recently, among the hot topics in the field of construction machinery, "the excavator is not able to walk well" has become the focus of many machine owners and maintenance technicians. This article will combine the hot content of the entire network in the past 10 days, analyze the common reasons why the excavator is unable to walk, and provide structured data to help readers quickly locate the problem.
1. Common reasons why the excavator has difficulty walking
According to discussions on maintenance forums and industry experts, inability to move an excavator is usually caused by the following reasons:
| Cause classification | specific questions | solution |
|---|---|---|
| Hydraulic system problems | Insufficient or contaminated hydraulic oil, insufficient pump pressure, stuck valve core | Replace hydraulic oil, clean filter elements, and overhaul hydraulic pumps |
| Travel motor failure | Internal wear of the motor and damaged seals | Replace motor or repair seal assembly |
| Track or chain problems | The track is too tight or too loose, and the chain is short of oil. | Adjust track tension and lubricate chain |
| Electrical control system failure | Sensor failure, poor circuit contact | Check circuit and replace sensor |
2. Analysis of recent hot cases
In the past 10 days, a video on a short video platform titled "Record of an excavator being unable to repair while walking" has sparked heated discussion. In this case, the owner neglected to change the hydraulic oil, resulting in insufficient oil supply to the traveling motor. The problem was finally solved by comprehensively cleaning the hydraulic system. Several maintenance technicians added in the comment area:"Hydraulic oil contamination is an invisible killer that causes inability to walk and needs to be tested regularly!"
3. Statistics of users’ high-frequency questions
| question | Frequency of occurrence (last 10 days) |
|---|---|
| Is the slow walking speed of the excavator related to the hydraulic oil? | 128 times |
| How to judge whether the walking motor is damaged? | 95 times |
| What is the standard for track tightness? | 67 times |
4. Prevention and maintenance suggestions
1.Change hydraulic oil regularly: It is recommended to replace it every 2000 working hours or half a year, and use the original model specified.
2.Check travel motor: If abnormal noise or oil leakage is found, stop the machine immediately for maintenance.
3.Track maintenance: Keep the tightness moderate (the amount of sag is usually 20-30mm) and avoid being too tight to increase the load on the motor.
5. Summary
The problem of the excavator having difficulty walking involves the cooperation of multiple systems and needs to be investigated one by one based on the specific performance. Through structured data and recent hot spot analysis, it can be seen thatHydraulic system maintenanceandWalking motor statusis the key. It is recommended that machine owners establish regular maintenance records to prevent problems before they occur.
If you cannot solve it by yourself, you should contact professional maintenance personnel in time to avoid small problems turning into major failures.
