Hydraulic actuators are devices that use pressurized fluid to create motion. They convert hydraulic energy into mechanical energy, allowing them to move heavy loads or perform tasks with precision. Commonly found in machinery, construction equipment, and vehicles, these actuators are essential for applications requiring significant force. The operation of hydraulic actuators relies on the principles of fluid mechanics. When hydraulic fluid is pumped into a cylinder, it pushes a piston, which then moves a connected component. This technology is widely used in systems like excavators, aircraft, and industrial machinery, making it a vital part of modern engineering and automation.
