Electric handling forklifts are currently widely used in industrial production, effectively improving work efficiency, but the equipment will inevitably fail during long-term use, how to solve some common failures.

ElectricHandling forkliftAt present, it is widely used in industrial production to effectively improve work efficiency, but the equipment will inevitably fail during long-term use. How to solve some common failures.

1. Jitter during lifting: There is air in the lifting cylinder, which can be solved by loading and lifting exhaust for many times during operation; when the hydraulic system leaks oil, the oil seal and hydraulic cylinder should be repaired and replaced in time.

2. Self-lowering with load: oil pipes and oil joints leak oil, and seals should be replaced in time; electromagnetic, manual reversing valve, and one-way valve are stuck by dirt or the sealing ring is worn, causing internal leakage. In case of such problems, the valve group should be cleaned in time or the seal should be replaced directly.

3. The lifting speed is too slow or unable to lift: when the oil tank is short of oil, the hydraulic oil needs to be replenished or replaced in time; when the pressure of the overflow valve is insufficient, it needs to be readjusted; the oil pump can be replaced when the oil pump is excessively worn or leaked; the solenoid valve, manual reversing valve, check valve, safety valve, valve wear or seal wear and aging, it should be updated in time. If the hydraulic oil temperature is too high for a long time, or the hydraulic oil deteriorates, the viscosity decreases, resulting in leakage, the hydraulic oil needs to be replaced in time.

4. ElectricHandling forkliftWhen walking, the abnormal noise of the driving wheel: the lubricating oil is mixed with hard debris, and the lubricating oil is updated; when the bearing is excessively worn or damaged, it should be replaced in time.

5. Electric handling forklift brake failure: If the equipment control circuit is not disconnected, check the equipment control system; if the brake friction plate is worn, it can be replaced in time;

6. The electric handling forklift does not move at all: check whether the forklift electric door lock is opened or damaged; check whether the battery is charged. When the battery is low, please charge it in time.

7. Abnormal movement back and forth: check whether the stroke control micro switch is loose, and lock the screws in time; check whether the battery is insufficient, replenish the power in time, and check whether the DC contactor is malfunctioning; if the electric control board is damaged, repair and replace it in time. When the drive motor fails, it should be checked and repaired in time; check whether the brake is locked, and adjust the distance between the drive wheel and the brake pad.

8. The battery has a short service life and cannot be charged: the electrolyte in the battery is insufficient, and distilled water and lead-acid water should be supplemented in time; when the battery is aging, the new battery should be replaced in time; when the power socket is in poor contact, the contact surface of the equipment should be repaired in time; When the battery is seriously lost or damaged, the unified battery should be replaced in time.

9. The charger does not work: when the charger does not have any display, the fuse is blown; when the charger power light is on, the internal fuse is short-circuited or the resistance is short-circuited, the rectifier tube is damaged, and the matching charger should be replaced in time.

The above is electricHandling forkliftCommon fault handling methods. When encountering some common failures, we can solve the problem in time through inspection, which can save a lot of time and avoid affecting the use of the equipment.
