Aerial Apparatus Specifics Flashcards
Three basic categories of aerial devices
aerial ladders, elevating platforms, and water towers
Types of elevating platforms
Aerial ladder platform, Telescoping aerial platform, and Articulating aerial platform
Four components of hydraulic system
Actuators, hydraulic fluid, hydraulic pump, and hydraulic reservoir
Pressures a hydraulic system might reach depending on manufacturer
3,500 psi
Prevents unintentional or undesirable motion of the device from its established position
Counterbalance valve
