To increase vehicle speed

To stabilize the apparatus and extend the aerial device

The purpose of hydraulic systems in aerial apparatus primarily revolves around stabilizing the vehicle and extending the aerial device. Hydraulic systems use fluid under pressure to multiply force and control movements. In the context of aerial apparatus, these systems enable the precise operation of stabilizers, which ensure that the vehicle remains steady during operations. This stability is crucial for the safe deployment and operation of the aerial device, whether it be for elevated access or for delivering water and personnel to higher locations.

Furthermore, the hydraulic system is responsible for extending and retracting the aerial ladder or platform, allowing firefighters to reach various heights effectively. This systemic setup ensures that the aerial device can be maneuvered smoothly and accurately, enhancing operational effectiveness in emergency situations.
