A hydraulic pressure jack uses a system of pistons and cylinders to create a large amount of force with a small amount of input. The pistons are connected to a pump, which is used to create the hydraulic pressure. This pressure is then transferred to the cylinders, which actuate the lifting mechanism. It is a mechanical arrangement that makes use of the power of the hydraulic fluids for operation. By having a hydraulic jack, by applying a small force, people can lift heavy loads. Generally, hydraulic pressure jack makes use of a hydraulic cylinder to apply initial power.
