ch7 stabilizing the apparatus Flashcards
the theoretical safety zone that surrounds the center of gravity on an aerial apparatus
Gravity circle
setting the stabilizers on one side of an apparatus shorter than the stabilizers on the other side
short-jacking
device that, when deployed, prevents the apparatus from tippings as the aerial device is extended away from the centerline of the chassis
stabilizer
Two-piece aerial apparatus stabilization device consisting of an arm that extends directly out from the vehicle and a lifting jack that extends from the end of the extension arm to the ground
box stabilizer (h-style stabilizer)
pnuematice systems require anywhere from blank to blank psi air pressure for the PTO to be operated
50-140
A rotating shaft that transfers power from the engine to auxiliary equipment
PTO system
Stabilization is ideally performed on?
even terrain
stabilizing device that extends at an angle down and away from the chassis of an aerial fire apparatus, also known as an A-frame stabilizer
Fulcrum-type stabilizer
what two types of unevenness are there and which one is easier to correct?
laterally, and longitudinally, lateral unevenness is easier to correct
correction of lateral unevenness can be achieved on grades up to blank and blank percent
5 and 6
most manufacturers recommend that the stbilizers on the blank side of the vehicle be lowered first
uphill
it is preferable that the aerial device be operated over the blank side of the apparatus
uphill
when operating at a longitudinal grade the aerial device should be operated either?
directly over the front or rear of the apparatus
the blank prevents the flow of hydraulic fluid into or out of the stabilization system while the aerial device is in use
interlock
the blank valves prevent the movement of fluid within the stabilization system
holding
