The pallet truck tells you how to solve the problem that the electric pallet truck cannot start

The electric pallet truck cannot walk.

1. First check whether the battery of the pallet truck of the electric pallet truck has voltage. If there is voltage, check whether the voltage can be used normally. Repair method: If the battery has no voltage or the voltage is too low, charge the battery directly.

2. Check whether the lifting switch and circuit of the lifting accessories of the electric pallet truck are loose or short-circuited, and whether the micro switch is damaged. Repair method: repair the cleaning circuit, replace or repair the micro switch.

3. Check whether the electric pallet lift truck contactor assembly of the electric pallet truck is burnt, and whether the coil is short-circuited or broken. Repair method: Repair the platinum contact of the contactor or directly replace the new hydraulic contactor assembly.

4. Check whether the electric pallet lift truck module of the electric pallet truck is burnt, short-circuited or disconnected. Repair method: Repair or replace the module assembly.

5. Check whether the hydraulic motor of the electric pallet truck has voltage, whether the motor has short circuit or open circuit leakage, and whether the carbon brush is seriously worn. Repair method: repair the circuit, replace the motor carbon brush, repair the copper head of the motor, repair the hydraulic motor assembly or replace the new hydraulic motor.

6. Check whether the hydraulic pump, multi-way valve, oil pipe and oil cylinder are damaged. Maintenance method: Check the hydraulic pump of the electric pallet truck or directly replace the new hydraulic pump assembly. If the multi-way valve is damaged, repair or directly replace the new multi-way valve assembly, directly replace the new hydraulic oil pipe, and replace the oil cylinder. Repair kit or replace with new cylinder assembly.

Expanding knowledge: How to investigate a problem with the steering system of an electric pallet jack?

When there is a problem with the steering system, a preliminary inspection is required. You must first understand the situation. Don't rush to remove the servo. Should be a component that needs to be checked later. There are many other components in the steering system. Therefore, other parts should be checked first.

First, check the steering wheel and tires of the electric pallet jack. When the steering gear is disengaged, whether the steering wheel and wheels rotate flexibly and without resistance, whether the tire size is suitable, and whether it is damaged. Then check the installation angle of the steering wheel of the electric pallet truck, that is, the positioning angle of the front wheel, check whether the pull rod system is abnormally loose or tight, and then check the king pin. The next step is to check other places that have been replaced before, such as repairing the replaced tubing, whether the tubing is oriented the wrong way, or if the diameter of the replaced tubing is too small. In this case, you will need to rearrange the twisted and bent tubing and replace it with a different one from the original. The next step is to check the oil storage tank of the power steering of the small electric pallet truck, make sure the oil reaches the correct level, check the drive belt of the pump, and adjust the belt according to the parameter requirements.
