FEATURES
- Two (2) and three (3) section, telescoping and articulating aluminum
boom mounted midship, constructed utilizing high-strength steel alloy
- Continuous 360 degree rotation
- Snozzle Model P50 operates 13' below grade
- Snozzle Model 652 operates 15' below grade
- Device installed rearward of the pump house, ahead of the body
LOWER BOOM ASSEMBLY (ELEVATION ASSEMBLY)- Lift cylinder
capable of elevating the waterway during maximum specified flow at all
nozzle angles and extension.
- Two (2) link arms provided on each side of the lower boom assembly,
pinned to the upper boom to provide articulating elevation from 0
degrees to 28 degrees above horizontal
- Both booms can move simultaneously with lift cylinder motion
UPPER BOOM (TELESCOPING ASSEMBLY)
- Upper boom reinforced to sustain all anticipated loads and nozzle reaction
force at full flow in all sweep directions
- Extension and retraction of the upper boom shall be by a hydraulic
cylinder providing a fully extended stroke of approximately 16'
- Telescoping sections shall be supported by Nycast Nyoil, (or equal),
pads for smooth, wear free operation
- Electrical cable shall be carried within flexible tube support
- Hydraulic hoses and electric cable contained inside the upper boom
assembly for maximum protection
- Two (2) Collins combination spot/floodlights with 750,000 peak
candle power attached to the nozzle assembly
NOZZLE SWEEP ASSEMBLY
- Consists of 3.5" internal diameter double swivel unit allowing the
nozzle to sweep in both horizontal and vertical planes
- Rotation allows the nozzle to be directed 45 degrees either side
of center for a 90 degree horizontal sweep
TURNTABLE ASSEMBLY- Turntable drive utilizes an external ring
gear with ball bearing rotation
- Ring gear is driven by a spur gear reduction input assembly
- This input assembly pinion is in turn driven by a low ratio worm
gear box via a reversible high torque, low-speed hydraulic motor
- Gear box design prevents drifting of the turntable
- Entire input assembly shall be mounted on a fabricated housing
NOZZLE AND CONTROL
- Nozzle is an automatic master stream type with a water/foam
flow range of 150-1500 gpm
- Nozzle control is a single joystick type with dual axis function
plus thumb button switch
HYDRAULIC CONTROLS
- Flow controls are electric, remote controlled, proportional type
- All hydraulic valves equipped with extended handle manual
overrides for emergency operation
- Single joystick type control provided for elevation, extension,
retraction and rotation operations
- Safety trigger lock prevents accidental boom movement if the
joystick is inadvertently moved
- Slide out tray under the pump panel provides adequate footing for
the Snozzle joystick operator
HYDRAULIC SUPPLY
- Hydraulic pump shall be of axial piston design with a displacement
of 2.83 cubic inch per revolution, rated at a continuous pressure of
2,500 pounds per square inch with an intermittent pressure rating of
3,000 pounds per square inch
- Self contained hydraulic power unity consisting of an integral
pump/motor provided as an alternative power source in the event of a
main hydraulic pump failure
AERIAL WATERWAY
- Can be operated in the stowed or deployed position
- Flow capacity of 1,500 gallons per minute
PUMPHOUSE
- A midship pumphouse, centered in the frame, ahead of body
- Valves-Akron standard (Elkhart optional)
- Pump pressure governor standard (option for a discharge relief valve
or TPM)
AERIAL BODY- Compartmentation fabricated from .125" 5052
aluminum, galvanneal steel, or stainless steel
- Side compartments integral assembly with the rear fender
- Neoprene elastomer isolators isolate chassis movement from the body
structure
- Bodies are formed and welded construction for durable, long lasting
design without the unnecessary weight
- Exclusive Pierce underslung steel body supports featuring 3-point
isolated mount system. This reduces torsional stress and road shock from
being transmitted into the body. The underslung design prevents
compartment floors from sagging after years of use.
- Aluminum extruded rub rails, bolted on for easy repair
- Galvanneal steel, stainless steel, high-strength aluminum
- Interior of all compartments are painted with multispec to hide
dirt, abrasions, and protect from oil, gas, and hydraulic spills
- Automotive-style hinged doors constructed with double pan, double
seals, enclosed latches, and .25" hinge pins
- Roll-up doors with lifetime warranty (available in satin or painted
finish)
- Handrails are Pierce's exclusive "cross knurled" design to reduce
hand slippage
