The power system is the core of the operation of the electric forklift, and the common faults are mostly related to the power supply and the motor. Abnormal battery power supply is a high-frequency problem, which is manifested as difficulty in starting the vehicle or sudden power failure. During the investigation, it is necessary to check whether the battery cable is loose and falling off, check the remaining power of the battery, and replenish the charge in time if the power is insufficient. If the power is sufficient and still cannot be powered, it is necessary to check whether the battery electrode is oxidized and corroded. Sand and clean the surface of the electrode with sandpaper and then tighten the wiring. If the motor starts up, it is necessary to check whether the fuse is blown. If the fuse is broken, replace the fuse of the same specification; if the fuse is normal, check whether there is a
The failure of the walking system directly affects the working efficiency of the forklift. Common problems include walking weakness and walking deviation. When walking weakness, first check whether the tire pressure is up to standard, and replenish it to the specified value in time when the tire pressure is insufficient; if the tire pressure is normal, check the wear of the carbon brush of the drive motor. Excessive wear of the carbon brush will lead to insufficient power output. Replace the suitable carbon brush to restore power. Walking deviation is mostly caused by uneven wear of the tires on both sides or misalignment of the steering system connecting rods. First compare the wear degree of the tires on both sides, and replace the tires with serious wear in time; if the tire condition is normal, check whether the steering link is loose or misplaced, adjust the position of the connecting rod and tighten the bolts to test the walking track.
The hydraulic system is responsible for the lifting operation of the forklift. Common faults include weak lifting and hydraulic leakage. When the lifting is weak, first check whether the hydraulic oil level is lower than the standard scale, and add hydraulic oil that meets the specifications when the liquid level is insufficient; if the liquid level is normal, check whether the hydraulic oil filter element is blocked. The blocked filter element will hinder the flow of oil. After replacing the new filter element, the lifting performance can be improved. Hydraulic leakage mostly occurs at YouTube joints or seals. Check whether the YouTube joints are loose during investigation, and tighten the loose joints in time. If the joints are normal, check whether the seals are aging and damaged, and replace the suitable seals to solve the leakage problem.
Daily basic maintenance can effectively reduce the frequency of failures. Operators need to regularly check the status of connectors, seals, and wearing parts of each system, do a good job of equipment cleaning, and avoid dust and debris from entering the gaps of components. Replace hydraulic oil, filter elements, and other consumables according to the specified cycle, and record the occurrence time, phenomenon, and treatment method of each failure to provide reference for subsequent troubleshooting.
