| Check Category | Check item | Inspection standards/methods | 正常/异常 |
|---|---|---|---|
| I. Appearance and Mechanics | 1. Components | Inspect the main beam, tilting arm, outriggers, etc., for obvious cracks, deformations, or weld breaks. | |
| 2. Twist lock mechanism | Check if the rotary lock is intact, whether the rotation/extension is flexible, and whether there is any wear or cracks. | ||
| 3. Hydraulic cylinders and pipelines | Check all cylinders for leaks, ensure pipe joints are secure, and inspect hoses for wear or bulges. | ||
| 4. Tires and axles | Check tire pressure/wear and whether the wheel bolts are tight. | ||
| II.Hydraulic System | 5. Hydraulic oil level | Check the fuel level gauge in the fuel tank to ensure that the fuel level is between the upper and lower marks. | |
| 6. Hydraulic oil status | Observe the color of the oil to see if it is transparent or pale yellow, and whether it is emulsified (whitened) or severely contaminated. | ||
| 7. Pumps and Motors | After starting the pump, listen to its running sound; it should be smooth without any sharp noises. | ||
| III.Electrical and Control Systems | 8. Cables and Connectors | Check the main cable and control cable for damage or exposure, and ensure the connectors are secure. | |
| 9. Control Panel and HMI | Check that the buttons and emergency stop switch are functioning properly, the HMI touchscreen display is clear, and there are no alarms. | ||
| 10. Sensors and Limits | Check if the tilt angle sensor and turnlock position sensor signals are normal (HMI display). | ||
| 11. Warning device | Test whether the warning lights and buzzers are working properly. | ||
| IV, Weighing System | 12. Instrument display | After power is applied, the weighing instrument should return to zero normally, and the display should be stable. | |
| 13. Sensor status | Check the HMI or instrument diagnostic menu to ensure that the four weighing points are evenly stressed and that there are no overload or failure alarms from any single sensor. | ||
| V,Functional Testing | 14. Outrigger lifting | The outriggers are raised and lowered smoothly and synchronously, and lock securely in place once in position. | |
| 15. Twist lock action | Test the locking/unlocking of the rotary locks to confirm that all rotary lock actions are consistent and the signal feedback is correct. | ||
| 16. Weighing test | Accuracy verification is performed by placing a known weight (such as a standard weight or a container of known weight), and the error should be within the allowable range. |
Inspection Conclusion: □ Everything is normal and ready for operation □ An abnormality was found and requires handling (see remarks)
