Recently, a netizen inquired about the reasons why hydraulic jacks cannot be installed. There are several possible reasons why hydraulic jacks cannot be installed.

Firstly, there may be leakage issues in the hydraulic system. Leakage of hydraulic oil can prevent the jack from establishing sufficient pressure to lift heavy objects. Checking for obvious oil stains or damage in hydraulic pipelines, seals, and cylinder bodies is key to identifying such issues.

Secondly, the quality and oil level of hydraulic oil may also affect the normal operation of the jack. If the hydraulic oil is contaminated, deteriorated, or the oil level is too low, it may cause the jack to fail to lift or lift weakly.

Furthermore, the working state of the hydraulic pump directly affects the lifting of the jack. If the internal parts of the pump are worn, blocked, or the driving mechanism fails, it may cause the hydraulic oil to be unable to be effectively delivered, thereby preventing the jack from lifting.

The failure of hydraulic jacks to lift may be the result of multiple factors working together. Through careful inspection and diagnosis, the root cause of the problem can be identified and corresponding repairs or replacements can be carried out to ensure its normal lifting function is restored.
