As an important construction machinery equipment, loaders often play an important role in construction, mining, highway construction and other fields. However, some common faults will inevitably occur during long-term use of loaders. This article focuses on the reasons why the loader lifting arm cannot be raised and the troubleshooting methods.
When the loader lifting arm cannot be raised, the possible reasons are:
1. Hydraulic system problems:
Check whether the oil level of the hydraulic system is normal, and also check whether there is oil leakage in the hydraulic pump, valves, etc.
2. Lifting arm hydraulic cylinder problem:
Check whether the hydraulic cylinder is normal and eliminate problems such as seal wear and internal failure of the hydraulic cylinder.
3. Hydraulic system adjustment issues:
Check whether the adjustment of the hydraulic system is reasonable, and adjust the hydraulic system if necessary.
