With continuous improvement, today's electric forklifts have become easier to operate, and the driving comfort has also been greatly improved. Electric forklifts will inevitably have some faults after a long time of use. At this time, it is necessary to investigate the faults.

2. The lifting speed is too slow or cannot be lifted. Causes of failure: lack of oil in the fuel tank, blockage of the oil filter, failure of the safety valve, high temperature of the hydraulic oil, too thin of the hydraulic oil, oil leakage in the hydraulic pipeline, damage to the hydraulic pump, etc. The abnormal noise when the gantry is lowered is generally due to damage or aging of the shockproof rubber.

Maintenance method: firstly check the joints, the gaskets of each component and whether there is oil leakage inside the structure, if any, replace it; deflate the system, if it still cannot be ruled out, disassemble and inspect it. If the working conditions of the hydraulic cylinder, gear pump and safety valve cannot be met, repair or replacement is required.

Cause of failure: there is air in the lifting hydraulic cylinder; poor performance of the gear pump; inflexible action of the lithium pallet truck reversing valve; unclean oil. Maintenance method: First, loosen the bleed plug on the hoisting hydraulic cylinder to release the air in the hoisting cylinder; check the cleanliness of the oil. If the jumping still cannot be solved, check the working condition of the reversing valve and gear pump. If they are not working well, they should be repaired or replaced directly.
