As an important engineering machinery equipment, loaders often play an important role in fields such as construction, mining, and highway construction.
However, during long-term use, loaders are inevitably prone to some common malfunctions.
This article will conduct an in-depth analysis of common faults and troubleshooting methods of loaders, so that users can solve problems in a timely manner and improve work efficiency during use.
1. When the engine of the loader cannot start, the possible reasons are:
(1) Fuel issue:
Check if the fuel is sufficient and eliminate any oil leaks in the fuel system.
(2) Battery issue:
Check if the battery is charged and maintain good battery and wire connections.
(3) Ignition system issue:
Check if the ignition system is functioning properly and eliminate any faults with the ignition coil, candle wire, etc.
2. When the walking track of a loader cannot move, possible reasons include:
(1) Hydraulic system issues:
Check if the oil level of the hydraulic system is normal, and also check if there is any oil leakage in the hydraulic pump, valves, etc.
(2) Track tightness issue:
Check if the tension of the track is appropriate and adjust the tension in a timely manner.
(3) Electrical system issues:
Check if the electrical system is functioning properly and eliminate issues such as poor wire contact and short circuits in the circuit.
3. When the lifting arm of the loader cannot be raised, the possible reasons are:
(1) Hydraulic system issues:
Check if the oil level of the hydraulic system is normal, and also check if there is any oil leakage in the hydraulic pump, valves, etc.
(2) Lifting arm hydraulic cylinder issue:
Check whether the hydraulic cylinder is normal, eliminate problems such as seal wear and internal faults 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.
4. When the control lever of the loader cannot be operated, the possible reasons are:
(1) Problem with the hydraulic cylinder of the control lever:
Check whether the hydraulic cylinder is normal, eliminate problems such as seal wear and internal faults of the hydraulic cylinder.
(2) Hydraulic system issues:
Check if the oil level of the hydraulic system is normal, and also check if there is any oil leakage in the hydraulic pump, valves, etc.
(3) Mechanical connection issue with joystick:
Check if the mechanical connectors are loose and tighten them in a timely manner.
The possible faults that may occur during the use of loaders mainly include engine failure to start, inability to move the walking tracks, inability to raise the lifting arm, and inability to operate the control lever.
We can determine the cause of these faults by checking the normal operation of components such as fuel, battery, ignition system, hydraulic system, and hydraulic cylinder, and promptly eliminate the problem.
When operating a loader, it is also important to regularly inspect and maintain the mechanical equipment to extend its service life and improve work efficiency.
I hope this article can provide a deep understanding of common faults and troubleshooting methods of loaders, and help readers solve problems in practical use to ensure smooth operation.
