A hydraulic drive is a system that uses pressurized fluid to transmit power and control movement. It operates by converting mechanical energy into hydraulic energy, allowing machines to perform tasks like lifting, pushing, or rotating. This technology is commonly found in construction equipment, such as excavators and bulldozers, where strong force is needed. The main components of a hydraulic drive include a pump, hydraulic fluid, and actuators. The pump generates pressure, which moves the hydraulic fluid through pipes to the actuators. These actuators then convert the hydraulic energy back into mechanical energy, enabling precise control of machinery and enhancing efficiency in various applications.
