The lack of power in the excavator's travel motor is a common but difficult problem, with various causes and solutions that vary depending on the situation.
Firstly, the reason for the excavator's weak walking may be due to a malfunction in the hydraulic system. The quality and quantity of hydraulic oil are key factors. If the hydraulic oil is insufficient or of poor quality, it will lead to insufficient pressure in the hydraulic system, which will affect the driving power. At this time, it is necessary to check the level of hydraulic oil and replace it with qualified hydraulic oil in a timely manner.
Secondly, the failure of the final drive can also cause the excavator to travel weakly. For example, the internal components of the motor are worn out, and the seals are aging and damaged. This may require disassembling the travel motor for detailed inspection and repair, and replacing damaged parts if necessary.
Furthermore, leakage of the central rotary joint may also be one of the causes. When the central rotary joint leaks, the hydraulic oil cannot transmit pressure normally, resulting in weak walking. In this case, it is necessary to replace the central rotary joint with a new one.
In addition, the improper tension of the track will also affect the walking performance. Loose tracks can easily lead to slipping and a lack of power during walking; If the track is too tight, it will increase the resistance to walking. Therefore, it is necessary to regularly check and adjust the tension of the track.
The following table compares the symptoms and preliminary troubleshooting methods of excavator walking weakness caused by different reasons:
The solution to the problem of excavator walking powerlessness is as follows:
reason | manifestation | preliminary troubleshooting methods |
Hydraulic oil problem | slow walking action, obvious sense of weakness | Check the fluid level and observe the oil quality |
The travel motor is faulty | There is an abnormal sound during travel and the speed is unstable. | Listen to the sound and check the appearance of the motor for leaks |
The central rotary joint leaks | the walking action is not coordinated, and one side is weak | Check whether there is oil leakage at the joint |
Improper tension of the track link | slipping or excessive resistance during walking | measuring the tension of the track link |
If it is a problem with the hydraulic oil, it should be supplemented or replaced with the required hydraulic oil in time, and the hydraulic system should be cleaned. For the malfunction of the traveling motor, professional technicians are required to repair or replace the parts. If the central rotary joint leaks, replace it with a new one as soon as possible and ensure that it is installed correctly. The adjustment of the track tension should be carried out according to the operation manual of the excavator.
In short, the problem of weak excavator travel requires comprehensive consideration of various possible causes, careful inspection and analysis, in order to accurately identify the problem and take effective measures to ensure the normal operation and efficiency of the excavator.
