What is the primary purpose of a hydraulic system in heavy-duty equipment?

The primary purpose of a hydraulic system in heavy-duty equipment is to transmit power through the use of hydraulic fluid. This is achieved by employing hydraulic fluid which is pressurized to create force and movement in various parts of the machine. Hydraulic systems are essential in heavy machinery because they allow for the efficient transfer of power, enabling various operations such as lifting, steering, and braking to be accomplished with precision and minimal physical effort.

Hydraulic systems are particularly advantageous as they can generate large amounts of force with relatively small components, making them ideal for heavy-duty applications where lifting or moving heavy loads is required. By using hydraulic cylinders or motors, the energy from the hydraulic fluid is converted into mechanical energy, demonstrating the system's effectiveness in applications ranging from excavators to bulldozers.

Storing mechanical energy, cooling engine components, and ensuring proper fuel combustion are not primary functions of hydraulic systems. While these functions are important for the overall performance of machinery, they do not directly relate to the hydraulic system's core role in power transmission.
