The electric pallet truck can't move forward and backward

When an electric pallet truck encounters a situation where it cannot move forward or backward during use, it often makes our operators helpless, and the equipment is relatively large. Encountering such a situation not only affects work efficiency, but also affects workshop work. normal development. When encountering this situation during the operation, we must first investigate the cause of the failure. The following editor will take you through a simple analysis.

1. The battery power of the device is low or the battery is faulty

Check the power of the device when turning on the power of the device, and charge it in time. If the battery cannot be charged normally, check whether the charger is faulty, and contact the manufacturer to replace the charger; check whether the charging port is loose or oxidized and rusted, resulting in poor contact and failure Charging; when the battery is used for too long, the performance degradation will also affect the normal use, and the battery accessories should be replaced in time.

2. The driving control switch is loose:

Check whether the driving control switch of the electric pallet truck is loose, which affects the normal operation, reinforce it in time, and tighten the screws.

3. The electric control board is damaged:

Damage to the electric control board of the electric pallet truck will also affect the normal forward and backward of the equipment, and it is necessary to contact special maintenance personnel for repair or replacement. During daily use, pay attention to the maintenance of the electric control board, and check whether the surface of the electric control board is burnt, air bubbles, damaged or rusted; you can also use a multimeter for maintenance.

4. Drive motor failure:

There are many reasons for the failure of the drive motor of the electric pallet truck, and we need to investigate them one by one. When the driving motor fails to start, it is necessary to check whether the fuse is blown, the control circuit is blocked, the motor is short-circuited, etc.; the temperature of the driving motor is too high, which may be caused by overloading during use, tight oil seal or poor lubrication, or excessive brush pressure Caused by other problems; sparks during the use of the motor may be caused by poor contact of the brush, incorrect brush position, etc., and repairs are performed according to different causes of the problem.

5. Brake failure:

The brake failure of the electric pallet truck may be due to the lack of regular maintenance of the brake system of the pallet truck, resulting in excessive impurities in the brake master cylinder, poor sealing, mixed use of brake fluid, and oil leakage due to clogged oil pipes. Improper operation can lead to mechanical failure of the equipment, such as manually adjusting the distance of the drive wheel brake pads; in addition, changing the oil in the brake cylinder of the pallet truck can also cause brake failure.

In short, there are many reasons why the electric pallet truck cannot move forward and backward. When we encounter problems, we should not disassemble the parts of the equipment at will. We must first check the cause of the failure and solve it according to the reason.
