What's Going On When The Excavator Deviates From Its Course?

The safety valve of the walking motor is leaking oil. If the safety valve leaks oil, the pressure inside the system will be too low, causing the rotational speed of the walking motor to be insufficient and thus resulting in walking deviation. The troubleshooting method is: Replace the damaged safety valve of the walking motor; When making a judgment, the left and right walking motors can be safely swapped to see if they deflect when moving in the opposite direction. If the spring inside the main valve of the excavator becomes soft or broken, or the valve core gets stuck, it may cause a decrease in oil pressure and result in the machine deviating to one side.
