What is hydraulic fluid primarily used for in heavy machinery?

Hydraulic fluid plays a crucial role in the operation of heavy machinery, particularly within hydraulic systems. Its primary function is to transmit power effectively. In hydraulic systems, the fluid is pressurized and used to move various components, enabling tasks such as lifting, pushing, or turning. The fluid's ability to transfer force from one point to another is essential for the operation of hydraulic cylinders and motors.

Additionally, hydraulic fluid also serves the purpose of lubricating moving parts within the system. This lubrication minimizes friction and wear on the components, ensuring smooth operation and extending the life of the machinery. The combination of power transmission and lubrication is what makes hydraulic fluid indispensable in heavy machinery applications, contributing significantly to performance and efficiency.
