The hydraulic jack has experienced oil leakage after prolonged use. Once this occurs, it is likely due to a problem with the sealing of the hydraulic jack. When this problem occurs, the load on the jack may not have a significant impact in the short term, but if left untreated, its load capacity will sharply decrease, ultimately leading to complete inability to lift.

When hydraulic jacks experience oil leakage, it is likely due to problems with the sealing ring. Prolonged use of the sealing ring can lead to oxidation, or prolonged exposure to high loads can cause the sealing ring to loosen. In such cases, what we need to do is replace the sealing ring.

Of course, in order to prevent this situation from happening, we need to avoid keeping the hydraulic jack in a high load state for a long time. After the work is completed, the load should be immediately unloaded, and the hydraulic jack should be placed in a good environment during use. This can effectively prevent hydraulic jack oil leakage
