Definition & Meaning of "hydraulic jack"

What is a "hydraulic jack"?

A hydraulic jack is a tool used to lift heavy objects, such as vehicles or machinery, by using hydraulic pressure. It consists of a cylinder filled with fluid, where a pump is used to apply pressure, raising the lifting arm and the object. This type of jack is known for its ability to lift heavy loads with minimal effort, as the hydraulic system provides a mechanical advantage. Hydraulic jacks are commonly used in car repairs, construction, and other industries that require lifting large or heavy objects, making them safer and more efficient compared to manual jacks.
