hydraulic machinery

Hydraulic machinery uses pressurized liquid, usually oil, to transmit force and perform work. They operate based on Pascal’s law, which states that a change in pressure applied to an enclosed fluid is transmitted equally throughout. This allows hydraulic systems to multiply force, enabling machines like excavators, cranes, and brakes to lift heavy loads or exert precise movements with relatively small input effort. The fluid flows through pumps, cylinders, and valves to control motion and force. Overall, hydraulic machinery efficiently converts fluid pressure into mechanical power, making it essential in construction, manufacturing, and transportation.
