Various Uses for Hydraulic Lifts

A hydraulic lift typically uses hydraulic cylinders to either raise or lower platforms for work, or other lifting devices. Hydraulic lifts are ideally used for support, as well as lift and move heavy to very heavy, and large objects; at the same time providing a safe environment that is ergonomically useful.

Hydraulic Cylinder - an overview | ScienceDirect Topics

A ram cylinder is a type of hydraulic cylinder that acts as a ram. A hydraulic ram is a device in which the cross-sectional area of the piston rod is more than one-half of the cross-sectional area of the moving components. Hydraulic rams are primarily used to push rather than pull, and are most commonly used in high-pressure applications.

A piston/cylinder with a cross-sectional area of 0.01 m3 has a mass of 100 kg resting on the stops as shown in the figure. With an outside atmospheric pressure of 100 kPa what should the water pressure be to lift the piston? Given: P 0 = 100 kPa, m piston = 100 kg, A piston = 0.01 m2. Find: The water pressure needed to lift the piston.

Using Manometers to Precisely Measure Pressure, Flow …

cross-sectional area of one leg of the manometer is many times larger than the area of the other leg. The larger area leg is called the well. As pressure is applied to the larger leg, the fluid moves down a minuscule amount compared to the increase in height of the small leg. This des1gn results m an ideal
