How to solve the problem that the electric pallet truck cannot start

The electric pallet truck cannot walk

1. First check the pallet truck battery of the electric pallet truck to see if there is 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 and clean up the circuit, replace or repair the micro switch.

3. Check whether the lifting contactor assembly of the electric pallet truck is burnt or 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 lifting module of the electric pallet truck is burnt or 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, check whether the motor has short circuit or open circuit leakage, and check whether the carbon brush is seriously worn. Repair method: repair the circuit, replace the motor carbon brush and repair the motor copper head, 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 of the electric pallet truck are damaged. Repair method: Check and repair 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.

Expanded knowledge: How to troubleshoot the steering system of the electric pallet truck?

When there is a problem with the steering system, you will need to perform a preliminary inspection. You must first understand the situation. Don't rush to remove the servo. Should be a component that needs to be checked later. In the steering system, there are many other components. cause failure, so check other parts first when checking.

First, check the electric pallet truck steering wheel and tires. When the steering gear is disengaged, check whether the steering wheel and wheels rotate flexibly and without resistance, whether the tire size is appropriate, and whether there is any damage. 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 tie rod system is abnormally loose or tight, and then check the ball joint and kingpin. The next step is to check other places that have been replaced before, such as repairing the replaced oil pipe, whether the direction of the pipe is wrong, or whether the diameter of the replaced oil pipe is too small and other constraints. If this happens, you will need to rearrange the twisted and bent tubing and replace the tubing that is not in its original condition. The final step is to check the oil storage tank for the power steering of the small electric pallet truck to make sure the oil is at the correct level, check the drive belt of the pump, and adjust the belt according to the parameter requirements.
