Pre-owned electric forklift units are widely used in warehouse handling, factory material transfer and other scenarios for their good cost performance, and the inspection of core components, especially the hydraulic system, is a key link to ensure stable daily operation. As a professional new energy enterprise focusing on electric forklift business, Jian Shu New Energy, which specializes in BYD electric forklift supply and supporting operation services, summarizes the standard practical hydraulic system performance inspection process for industry reference, you can send consultation mail to 17399989919@163.com for more professional supporting services.
First, complete the visual check of external hydraulic components. Check all hydraulic pipeline joints, sealing elements, cylinder rod surfaces, oil tank shell to see if there are traces of oil leakage, scratch or aging deformation, confirm the hydraulic oil level is kept within the specified scale range, and observe whether the hydraulic oil has obvious emulsification, impurity precipitation or abnormal discoloration.
Second, conduct no-load performance test. Start the forklift power system, control the hydraulic operation lever to complete full extension and retraction actions of lifting cylinder, tilt cylinder and steering cylinder for 3 to 5 repeated cycles, record the smoothness of each action, to make sure there is no stuck, jitter or obvious lag phenomenon in the whole operation process.
Third, carry out load performance verification. Place the matched standard load on the fork, operate the hydraulic system to complete full height lifting, forward and backward tilting, full angle steering actions, check whether there is abnormal automatic sliding of the gantry or unsmooth steering situation, test the system working pressure with professional measuring tool to confirm it stays within the factory specified range.
After finishing the above inspection steps, record all abnormal points and make reasonable maintenance adjustment, can effectively reduce the later operation failure rate of pre-owned electric forklifts and extend the service life of hydraulic components.
