One key advantage of hydraulic systems over mechanical systems is the higher power-to-weight ratio. Hydraulics utilize liquids to transmit power, allowing them to exert great force with relatively small components. This capability enables machines equipped with hydraulic systems to be lighter and more compact compared to mechanical systems, which often require heavier structures to handle the same levels of force.

The use of hydraulic fluid allows for the transfer of power without the need for large, heavy components that would be necessary to achieve similar results in a mechanical system. Consequently, hydraulic systems can achieve significant lifting or operational power without adding excessive weight, making them particularly useful in applications such as construction equipment, automotive systems, and aviation. This characteristic is crucial in situations where maintaining a lower weight for better mobility and efficiency is essential.
