How to repair the circuit of an electric forklift?

As we all know, electric forklift are mechanical vehicles that use electric power to drive lifting and walking. Therefore, the importance of circuit systems for forklift trucks is self-evident. Once there is a problem with the electrical system, the entire electric forklift will get into trouble, seriously affecting its normal operation. Next, regardless of the price of forklift for sale, the electric forklift manufacturer will tell you how to repair the oil pump circuit and steering circuit of electric forklifts.

First, let's talk about troubleshooting the oil pump circuit of an electric forklift. Due to the fact that the oil pump circuit is not controlled by the governor control board, and the contactor coil is directly controlled by the oil pump switch, the oil pump circuit resistance only occurs in external circuits. The main obstacle of the oil pump circuit is that the oil pump motor cannot operate normally. During the inspection, the first step is to check whether the incense seat or handle switch is closed, whether the oil pump circuit fuse is burned out, whether the oil pump switch is in good contact, or whether the contactor switch has a short circuit, open circuit, or mechanical jamming. The electric forklift manufacturer tells everyone that regardless of the price of the forklift for sale, it is also necessary to check whether there are short circuits, open circuits in the two windings of the motor, and whether the brushes are in good contact.

Let's talk about how to repair the steering circuit of an electric forklift when it fails. Due to the fact that the steering circuit contact is controlled by the governor control board, steering circuit faults can be divided into internal circuit faults and external circuit faults. During inspection, the external circuit should be checked first to determine whether there is a fault in the internal circuit based on troubleshooting the external circuit. When checking the steering circuit fault, first check whether the seat or handle switch is closed and whether the steering fuse is burnt out; Then, check whether there is a short circuit or open circuit in the contactor coil, and whether the contactor contacts can be closed or mechanically stuck; Check whether there is a short circuit or open circuit between the two windings of the motor, and whether the brush contact is good. The electric forklift manufacturer tells everyone that regardless of the price of the forklift for sale, if the external circuits are working normally, it is an internal fault in the control board, and the control board should be replaced.

The above is the method for repairing the oil pump circuit and steering circuit of electric forklift. If there is a circuit fault, the forklift operator can follow the above methods to troubleshoot the fault and repair it in a timely manner. Regardless of the price of a forklift for sale, circuit failures can be tricky. The electric forklift manufacturer recommends that if you cannot solve them on your own, it is most appropriate to find professional maintenance personnel to handle them.
