Proposal Number PSDF #P09-0004
Safety Features
The outrigger system provides the following minimum safety features:
1. Amber indicator light at the outrigger control station shall indicate circuit completion to show that
the unit is ready for aerial operation.
2. Red warning lights at the outrigger and aerial operator's control consoles shall warn the operator
that one (1) or more outriggers has been short set.
3. An aerial/outrigger interlock system shall be provided to prevent the lifting of the aerial from the
nested position until the operator places all jacks in the load supporting configuration. An
electrical can-bus encoder system at the ladder pivot prevents operation of the outriggers once the
aerial has been elevated from the nested position.
4. Ground illumination lights shall be provided to illuminate the area directly under the outriggers
for each extending outrigger.
5. A light will be provided in the cab to alert the operator when the outrigger is not in the stowed
position.
Outrigger and Stabilizer Specifications
The specified outriggers and torque box system shall provide a 1-1/2 to 1 stability safety factor when the
aerial is in any operating position.
The stability requirements shall be met by the apparatus on which the aerial device is mounted when that
apparatus is in a service-ready condition but with all normally removable items such as water, hose, ground
ladders, and loose equipment removed.
The aerial device shall be capable of sustaining a static load 1-1/3 times its rated capacity in every position in
which the aerial device can be placed when the apparatus is on a slope of 5 degrees downward in the
direction most likely to cause overturning.
All outriggers and stabilizers that protrude beyond the body of the apparatus shall be striped or painted with
reflective material so as to indicate a hazard or obstruction. Each outrigger or stabilizer shall also be
provided with one or more red warning light(s) located either on the stabilizer or in the body panel visible on
the side of the apparatus where the stabilizer is located.
FRONT AND REAR OUTRIGGERS
Two (2) front and two (2) rear out and down H-style outriggers shall be provided on the apparatus. The rear
outriggers shall be located directly behind the rear axle and the front outriggers shall be connected to the
front of the torque box. These units shall be equipped with manual outrigger control valves. The controls
shall be located at the rear and to the outside of the chassis. This location shall give the operator full view
and control of each outrigger. All controls handles shall move in the same direction as the outrigger
movement.
