Hydraulic jacking products are tools that use high-pressure fluid, usually oil, to lift weight. It works by utilizing Pascal's principle of applying a pressure in a closed container which is transmitted uniformly to all parts of the container through the incompressibility of the liquid.

Hydraulic jacking products usually consist of a cylinder capable of holding pressure, a steel bar and a platform. The steel bar is fixed in the oil cylinder, and there is a detachable platform at the bottom, on which the weight to be lifted can be fixed. When the hydraulic jacking products need to be used, an oil pipe is inserted into the pipeline, and the hydraulic oil is filled into the oil cylinder through the pump. As the oil flows in, the steel rod is stressed and begins to lift the weight on the platform.

Hydraulic jacking products are widely used in various industrial fields, such as automobile maintenance, construction of large buildings, aerospace, petrochemical and so on. It has the advantages of simple operation, light weight, small footprint, can withstand large pressure and weight, and has good stability and reliability.

It should be noted that when using hydraulic jacking products, it must be ensured that the pressure and weight will not exceed its design range. In addition, hydraulic oil and seals need to be inspected and replaced regularly to ensure their proper function and prolong their service life.
