What is the primary purpose of a hydraulic system in an aerial apparatus?

The primary purpose of a hydraulic system in an aerial apparatus is to facilitate the movement of the aerial platform. Hydraulic systems use fluid under pressure to transmit force and control the motion of the aerial device, allowing it to extend, retract, and reposition accurately. This is crucial for achieving the necessary height and reach to safely deploy personnel and equipment in firefighting operations.

By harnessing the power of hydraulics, the aerial apparatus can elevate the platform to desired heights, maneuver around obstacles, and adjust angles for optimal access to areas needing attention. The efficiency and precision provided by hydraulic systems are essential for effective aerial firefighting and rescue efforts.
