Hydraulic control refers to the use of pressurized fluid to operate machinery and equipment. This system relies on the principles of hydraulics, where liquids are used to transmit power. Common applications include construction machinery, such as excavators and cranes, which utilize hydraulic systems to lift heavy loads and perform precise movements. In hydraulic control systems, components like pumps, valves, and cylinders work together to manage the flow and pressure of the fluid. By adjusting these elements, operators can control the speed and force of the machinery, making hydraulic control essential for tasks that require strength and accuracy in various industries, including manufacturing and automotive.
