If the car tailboard malfunctions, you can follow the following steps to troubleshoot and repair it:

1、 Troubleshooting

Observe the appearance

Firstly, carefully observe the appearance of the car tailboard and check for any obvious damage, such as deformation, cracks, oil leakage, etc. At the same time, check whether each connecting part is loose or detached.

Check the electrical system

(1) Check if the power connection is normal, including batteries, fuses, relays, etc. Ensure that the power cord is not damaged, short circuited, or has poor contact.

(2) Check if the control buttons and switches are working properly. When pressing the button, observe whether the indicator light is on and whether the tailboard has the corresponding action.

(3) Check the operation of the motor and hydraulic pump. Listen for any abnormal noise from the motor and observe if there are any oil leaks, insufficient pressure, or other issues with the hydraulic pump.

Check the hydraulic system

(1) Check if the hydraulic oil level is normal. If the liquid level is too low, it may cause the tailboard to malfunction. Add hydraulic oil to the appropriate level in a timely manner.

(2) Check if there is any oil leakage, blockage or damage in the hydraulic pipeline. If there is a problem, the pipeline should be replaced or repaired in a timely manner.

(3) Check the working condition of the hydraulic cylinder. Observe whether the hydraulic cylinder has leaks, poor expansion and contraction, and other issues. You can manually operate the tailboard to check if the hydraulic cylinder is functioning properly.

Check the mechanical structure

(1) Check whether the hinges, shafts, sliders, and other mechanical components of the tailboard are worn, loose, or deformed. If there are any problems, they should be replaced or repaired in a timely manner.

(2) Check if the locking device of the tailboard is working properly. Ensure that the tailboard can be securely locked during the lifting and lowering process.

2、 Fault repair

Electrical system malfunction

(1) If the power connection is poor, the power cord should be reconnected to ensure good contact.

(2) If the control button or switch is damaged, a new button or switch should be replaced.

(3) If the motor or hydraulic pump malfunctions, it should be repaired or replaced according to the specific situation.

Hydraulic system malfunction

(1) If the hydraulic oil level is too low, an appropriate amount of hydraulic oil should be added. At the same time, check for any leaks in the hydraulic system and promptly repair the leak points.

(2) If the hydraulic pipeline is blocked, the pipeline should be cleaned or replaced. If the pipeline is damaged, it should be replaced in a timely manner.

(3) If the hydraulic cylinder leaks, the seal should be replaced. If the hydraulic cylinder does not extend and contract smoothly, it may be due to impurities or damage inside, and should be cleaned or repaired.

Mechanical structural failure

(1) If mechanical components are worn or loose, they should be replaced or tightened in a timely manner.

(2) If the locking device of the tailboard malfunctions, the locking mechanism should be checked for damage and repaired or replaced in a timely manner.

When troubleshooting and repairing car tailboards, it is important to pay attention to safety. If you are unable to determine the cause of the malfunction or carry out repairs, you should promptly contact professional car maintenance personnel for handling. At the same time, regular maintenance of the car tailboard can effectively reduce the occurrence of faults and extend the service life of the tailboard.
