The electric truck tells you how to deal with the electric truck that cannot be lifted

Electric trucks are mainly used in factories for freight handling. It can be said that they can be seen everywhere in factories and warehouses, but there is also one, that is, long-term use, there are more or less some faults, such as It can't be upgraded normally, abnormal sound occurs when using it, etc. Do you want to know how to deal with these problems? The electric pallet truck manufacturer will tell you what problems will occur after long-term use of the electric pallet truck!

1. Trembling occurs during lifting

Solution:

1. There is air in the lifting cylinder, which can be solved by exhausting the load multiple times;< /p>

2. The hydraulic system leaks oil, repair or replace it;

2. Self-lowering when there is a load

Solution:

1. If there is oil leakage in the pipeline or oil line joint, replace the seal;

2. The solenoid, manual reversing valve and one-way valve are stuck with stolen goods or the sealing ring is worn, resulting in internal leakage, and the cleaning valve group should be replaced. Seals;

Three, the lifting speed is too slow or cannot be lifted

Solution:

1 , The oil tank is short of oil, and hydraulic oil needs to be replenished or completely replaced;

2. The oil filter is blocked and needs to be cleaned with kerosene;

3. The pressure of the relief valve is insufficient, and readjust ;

4. Excessive wear of the oil pump causes internal leakage and needs to be replaced;

5. The electromagnetic, manual reversing valve, check valve is worn or the seal is worn and aged, and needs to be replaced;< /p>

6. The seals of the lifting cylinder are worn, aged and need to be replaced;

7. The hydraulic oil temperature is too high for a long time, and the hydraulic oil deteriorates and the viscosity decreases, resulting in leakage, so replace the hydraulic oil;

Fourth, the driving wheel produces abnormal noise

Solution:

1. The lubricating oil is mixed with hard impurities, and the lubricating oil should be replaced;

p>

2. The bearing is excessively worn or damaged and needs to be replaced;

5. Brake failure

Solution:

1. The control circuit is not Disconnect, scissor control system;

2. The brake pads are worn and need to be replaced;

6. Completely immobile

Solution:

p>

1. Check whether the electric door lock is open or not;

2. Whether the battery has electricity, the animal battery is not enough, and it needs to be replenished;

3 , Whether the power socket has been plugged in tightly, whether the emergency switch is disconnected, and whether the fuse in the machine is blown; , then the electric pallet truck cannot be used normally. The solution to this problem is that the micro switch in the control switch is loose or malfunctioning, the reset switch spring is loose, and the screw can be locked; the hydraulic oil valve oil circuit is blocked and needs to be cleaned; The wiring of the DC contactor for lifting is loose or fails. If the descending speed is too fast, the hydraulic valve flow can be used too large or too small, and the slow flow valve can be replaced, 'big is fast, small is slow'.
