1 Aerial Apparatus Operator Apparatus Stabilization

2 Most critical aspect of preparing aerial Broaden base of vehicle to avoid tipping over Widen chassis beyond the wheels

3 Hydraulic System Hydraulic pump Oil Reservoir Filters and exchange type oil coolers Hydraulic oil supply tubing Valves Auxiliary hydraulic pump

4 Transferring Power to Hydraulic System Position according to conditions Engage PTO –according to transmission type

5 Setting Stabilizers Chock wheels Check around vehicle Check surface where stabilizers will rest –place foot plates

6 Selector Valve Location –midship –rear step Method of Operation –varies by manufacturer Once in place apparatus read for stabilization

7 Stabilization on Even Terrain Allows for maximum stabilization Lift weight off one side –until tire bulge is removed Then lift other side and alternate lifting

8 Stabilizing on Uneven Terrain Should only be done when unavoidable Correcting lateral unevenness –can correct up to 5-6% grade –stabilize high side first Longitudinal unevenness –maximum varies from 6-14%

9 Stabilizing on Curbs Should be avoided if possible Same as lateral incline Reposition if possible Object must be capable of withstanding weight

10 Locking Stabilizers Assures stabilizers stay in place Holding valves and interlock are most common system Box stabilizers have holes for safety pins Position wheel chocks at this time

11 Stabilizing Tractor-Trailer Type Apparatus Stability given by way apparatus is parked Angle should be placed between tractor and trailer –60 degrees –never more than 90 degrees

12 Video Stabilizing Aerial Apparatus Action Training Systems
