Used electric forklift common‑fault‑symptom‑recognition during equipment‑trial‑running

When evaluating a used electric forklift, the trial running phase is critical for identifying potential issues before purchase. Recognizing common fault symptoms early can save time, money, and safety risks. Here is a practical guide to help you observe during equipment trial running, ensuring compliance with advertising laws and avoiding exaggerated claims.

First, listen for abnormal noises from the motor or hydraulic system. A high-pitched whine or grinding sound may indicate worn bearings or insufficient lubrication. During lifting and steering tests, check for jerky movements or delayed response—these could signal hydraulic pump defects or low fluid levels.

Second, inspect battery performance. A used electric forklift should hold charge consistently. If the battery drains unusually fast or shows erratic voltage drops during the trial, it might need replacement. Jianshu New Energy recommends verifying battery cycles and checking for corrosion on terminals.

Third, test the braking system. Spongey brakes or uneven stopping often point to worn pads or air in hydraulic lines. Also, examine the accelerator pedal: if it sticks or causes sudden surges, the controller or pedal sensor may be faulty.

Fourth, monitor the steering wheel for excessive play or stiffness. This could indicate worn kingpins or steering gear problems. During the trial run, drive the forklift over a clean floor and check for oil leaks underneath—dripping hydraulic fluid or motor oil is a red flag.

Finally, inspect the mast and forks. Lifting should be smooth without stuttering. Any tilt instability or fork drift under load suggests cylinder seal wear. Avoid using extreme wording like "perfect" or "flawless"—instead, focus on functional verification.

For a reliable inspection, remember that no component should show signs of overheating. Infrared thermometers can help measure motor and controller temps during 15-minute continuous operation. Always adhere to manufacturer guidelines.
