Topic: Overhead Crane Maintenance Troubleshooting

In the daily operation of the Crane factory, some minor faults and malfunctions sometimes appear, which requires the driver to be able to handle and eliminate these faults.



(1) If the brake fails, the car cannot brake, and the sliding distance of large and small cars is too large after power failure, which may be caused by oil pollution on the brake surface, severe wear of the brake lining, improper adjustment of the main spring, or fatigue and aging. In view of this situation, corresponding measures should be taken, such as cleaning the brake working surface with kerosene, replacing the aging lining, and adjusting the tension of the main spring.



   (2) If the brake cannot be opened, the motor emits abnormal noise, the lining emits a burning smell and smoke, it may be that the main spring is too tight, the lining is stuck on the brake wheel or the living hinge is stuck, and the working surface area of the brake wheel is damaged. The lining should also be cleaned; remove debris from the stuck area, and lubricate the hinge with engine oil. Adjust the main spring to meet the standard requirements.



(3) There are still some uncommon faults, but if they happen, our crane drivers cannot solve them. Of course, they do not appear suddenly, but slowly form along the life of the crane. For example, the gears of the reduction gearbox are severely worn, resulting in excessive backlash on the gear side, resulting in mechanism vibration; rail gnawing in the cart; fatigue cracks, deformation of the main beam, and deflection. Appears in metal mechanisms. Due to the friction between the components that make up the crane, it is a factor of wear, corrosion and aging of the components. When these damages reach a certain level, if they cannot be repaired or have no repair value, they should be scrapped immediately.
