As a new type of electric logistics handling equipment, all-electric narrow pallet jack have already occupied a place in the vast market. With the increasing number of companies using electric walkie pallet jack in the market, there are more and more concerns about the failures of electric narrow pallet jack in use. How to effectively avoid or eliminate the troubles of electric walkie pallet jack has become a concern of business owners. Thinking about the problem.

 


According to such problems, we have specially collected and summarized some problems that are easy to occur in the application process of electric narrow pallet jack and how to solve and eliminate such problems in the communication and discussion with the company's engineering and technical personnel.


Symptoms and troubleshooting methods:


First, the electric walkie pallet jack trembles when lifting
1. There is air in the lifting cylinder of the electric narrow pallet jack, and the electric pallet truck can be solved by the load multiple times and the lifting method exhausting.
2. The hydraulic system of the electric walkie pallet jack leaks oil, repairs and replaces the oil seal and hydraulic cylinder of the electric narrow pallet jack.


Second, the electric walkie pallet jack is self-decreasing when there is load
1. The oil pipe or oil pipe joint of the electric narrow pallet jack has oil leakage, and the seal can be replaced.
2. Electromagnetic, manual reversing valve, check valve of electric walkie pallet jack has dirt stuck or seal ring wear, resulting in internal leakage. Treatment: Clean the valve block replacement seal of the electric narrow pallet jack.


Third, the electric walkie pallet jack is lifting too slow or can not lift
1. The fuel tank of the electric narrow pallet jack is short of oil and needs to be filled with hydraulic oil or replaced completely.
2. The pressure of the electric walkie pallet jack overflow valve is insufficient and readjusted.
3. The oil pump of the electric narrow pallet jack is excessively worn, causing internal leakage and needs to be replaced.
4. Electromagnetic, manual reversing valve, check valve, safety valve wear or seal wear aging of electric trucks need to be updated.
5. The hydraulic oil temperature of the electric walkie pallet jack is too high for a long time. The hydraulic oil is degraded and the viscosity is lowered, and a leak occurs, and the hydraulic oil is replaced.


Fourth,the driving wheel produces an abnormal sound when the electric narrow pallet jack is walking.
1. The hard oil of the electric walkie pallet jack is mixed with hard materials and the lubricating oil is updated.
2. The bearing of the electric narrow pallet jack is excessively worn or damaged and needs to be replaced.


Fifth,brake failure of electric walkie pallet jack
1. The control circuit of the electric narrow pallet jack is not disconnected and the control system is checked.
2. The brake lining of the electric walkie pallet jack is worn and replaced.


Sixth, the electric truck is completely motionless
1. Check if the electric door lock of the electric truck is open or not.
2. Check if the battery of the electric truck has electricity, the battery is low, and the battery is replenished.


Seven, electric narrow pallet jack can not advance or retreat
1. The battery of the electric walkie pallet jack is not enough to replenish the battery.
2. Electric walkie pallet jack travel control The micro switch is loose and the screws are locked.
3. The DC contactor of the electric narrow pallet jack is out of order, repair and replacement.
4. The electric control board of the electric narrow pallet jack is damaged, repaired and replaced.
5. The drive motor of the electric walkie pallet jack is faulty, check and repair.
6. The brake of the electric narrow pallet jack is locked and the distance between the brake pads of the drive wheel is adjusted.

 


Eight, electric walkie pallet jack battery life is short and can not be charged
1. The battery of the electric narrow pallet jack is insufficient in electric solution, supplemented with distilled water or lead acid water.
2. The battery of the electric walkie pallet jack is aged and replaced with a new one.
3. The power socket of the electric narrow pallet jack is in poor contact and the contact surface is trimmed.
4. The battery of the electric walkie pallet jack is severely damaged, damaged, and replaced with a unified battery.


Nine, the charger of the electric narrow pallet jack does not work
1. The charger of the electric walkie pallet jack does not have any display, the breaker is blown
2. The power supply lamp of the electric narrow pallet jack is bright, the internal breaker is open or the resistance is broken, and the rectifier is damaged.
