Do you know the 9-point fault and troubleshooting method of the all-electric hydraulic truck?

As a new type of electric logistics handling equipment, all-electric hydraulic trucks have already occupied a place in the vast market. With the increasing number of companies using electric pallet trucks in the market, there are more and more concerns about the failure of electric pallet trucks in use. How to effectively avoid or eliminate electric pallet trucks? The hidden trouble of failure has also become a problem for business owners to worry about.

According to such problems, we specially collected and summarized some of the problems that are easy to occur in the application process of all-electric hydraulic handling in the communication and discussion with the company's engineering and technical personnel. How to solve and eliminate such problems.
Fault phenomenon and troubleshooting method:
1. Trembling occurs when the all-electric hydraulic pallet truck is lifted
1. There is air in the lifting cylinder of the all-electric hydraulic pallet truck, and the electric pallet truck can pass multiple loads. 2. Oil leakage of the hydraulic system of the all-electric hydraulic truck, repair and replace the oil seal and hydraulic cylinder of the all-electric hydraulic truck.

Second, the electric pallet truck automatically descends when it has a load
1. The oil pipe or oil line joint of the electric pallet truck has oil leakage, and the seal can be replaced.
2. The electromagnetic, manual reversing valve and one-way valve of the electric pallet truck are stuck with dirt or the sealing ring is worn, resulting in internal leakage. Treatment method: Clean the valve group of the electric pallet truck and replace the seal.

Three, the lifting speed of the all-electric hydraulic truck is too slow or cannot be lifted
1. The fuel tank of the all-electric hydraulic truck is short of oil, and it is necessary to add hydraulic oil or replace it all.
2. If the pressure of the relief valve of the all-electric hydraulic truck is insufficient, adjust it again.
3. The oil pump of the all-electric hydraulic truck is excessively worn, resulting in internal leakage and needs to be replaced.
4. The electromagnetic, manual reversing valve, check valve and safety valve of the all-electric hydraulic truck are worn or worn and aged, and need to be updated.
5. The hydraulic oil temperature of the all-electric hydraulic truck is too high for a long time, and the hydraulic oil deteriorates and the viscosity decreases, resulting in leakage, and the hydraulic oil should be replaced.

Fourth, the driving wheel of the electric pallet truck makes an abnormal noise when the pallet truck is walking
1. The lubricating oil of the pallet truck of the electric pallet truck is mixed with hard Sundries, update the lubricating oil
2. The bearings of the electric pallet truck are excessively worn or damaged and need to be replaced.

V. Brake failure of the electric pallet truck
1. The control circuit of the pallet truck of the electric pallet truck is not disconnected, check the control system.
2. The brake pads of the electric pallet truck are worn and replaced.

6. The all-electric hydraulic pallet truck does not move at all
1. Check whether the electric door lock of the all-electric hydraulic pallet truck is open or damaged.
2. Check whether the battery of the all-electric hydraulic truck has electricity, if the battery is insufficient, replenish the battery.

Seven, the electric pallet truck cannot move forward or backward
1. The battery power of the electric pallet truck is insufficient, replenish the power.
2. Loosen the micro switch of the electric pallet truck's walking control, and tighten the screw.
3. The DC contactor of the electric pallet truck fails, repair and replace it.
4. The electric control board of the all-electric hydraulic truck is damaged, repaired and replaced.
5. The drive motor of the all-electric hydraulic truck is faulty, check and repair.
6. The brakes of the all-electric hydraulic truck are locked, and the distance between the brake pads of the driving wheel is adjusted.

VIII. The battery of the all-electric hydraulic truck has a short usage time and cannot be charged
1. The battery of the all-electric hydraulic truck is insufficient, and supplementary distilled water or lead Acidic water
2. The battery of the all-electric hydraulic truck is aging, replace it with a new one.
3. The power socket of the electric pallet truck is in poor contact, and the contact surface is trimmed.
4. The battery of the electric pallet truck is seriously broken and damaged, and the unified battery should be replaced.

9. The charger of the electric pallet truck does not work
1. The charger of the electric pallet truck does not have any display, and the breaker is blown
2 . The charger power light of the electric pallet truck is on, the internal capacitor circuit breaker is open circuit or resistive circuit circuit, and the rectifier tube is damaged.
