Pneumatic hydraulic jack is a high-level lifting jack that combines pneumatic jack device and hydraulic jack device into one. It uses compressed gas to push the pneumatic pump to work, and the hydraulic oil in the oil storage tank will be injected into the oil cylinder, causing the telescopic hydraulic cylinder to rise or fall, achieving a relaxed and effortless lifting effect. So, how long does this lifting time usually take?

Taking an ordinary jack as an example, when the rated air pressure is 1.1 MPa, the test result for a 30 ton jack is 8 seconds, and for a 120 ton jack it is 20 seconds. Compared to a screw jack or hydraulic jack, this lifting time is relatively fast, which can greatly improve work efficiency and save work time. Although the upward speed of the pneumatic jack is fast, it is relatively stable and safe when descending.

The above lifting time is the ideal lifting time, and the time for pneumatic hydraulic jacks to lift heavy objects is also influenced by multiple factors such as the physical strength of the workers, the ground, the weight of the heavy objects, and the quality of hydraulic oil.
