FEATURES
- Five section telescoping steel ladder constructed of high strength
steel, certified to 70,000 psi
- Aerial device mid-mounted behind the cab to torque box sub-weldment
with front and rear stabilizers and the ability to short-jack
- Bolt-on egress with full 750 lb. rating
- Modular body construction allows for easy component replacement if
damage were to occur
- Electronically controlled, multiplexed and microprocessor-based
system
LADDER ASSEMBLY
- Ladder sections are trussed vertically and diagonally with round steel
tubing
- Environmentally sealed ladder sections to protect against corrosion
- All ladder rungs are round and welded to each section in two places
with K-Bracing for rigidity
- Ladder sections are designed with adequate hand spacing and room for
vertically mounted cable tracking, resulting in unobstructed egress on
ladder
- Ladder section overlap of 85" for strong joints, improved torsional
resistance and reduced movement
- Rungs are sheathed with an aggressive composite luminescent rung
covers increase visibility during egress and do not need electrical
connections or amp draw
- Extension and retraction motion by a dual hydraulic powered
cylinders and cable pulley system
- Rotation motion through a swing bearing/spur gear, driven by a
planetary hydraulic motor
- Elevation motion through two double acting, lift cylinders (8
degrees below horizontal to 75 degrees above)
- All cylinders designed with integral holding valve cartridges in the
event of a hydraulic line failure
- Rotational brake applies when pressure control is released
TURNTABLE DECK
- 102" wide turntable is constructed of 1" thick deck, coated with a
non-skid, chemical resistant material
- Access to the turntable is from front body stair wells, one each
side of the truck
- Stairs are lit by two lights activated by the aerial master switch
- Includes control console and space for hydraulic and electrical
components
- Rotation motion through a 54 inch swing bearing/spur gear, driven by
two hydraulic planetary gear boxes
AERIAL DEVICE POWER
- One turntable control station
- Aerial controls are electronic over hydraulic, fully multiplexed and
proportionate
- All aerial device controls have fail-safe manual hydraulic
overrides.
- Hydraulic load sensing piston pump, capable of multiple-function
operation without speed loss.
- High pressure hydraulic manifold block, with test ports
- Pressure and relief filtration system
- Hydraulic reservoir of 70 gallons
- Relief valve set at 3,150 psi to protect hydraulic system components
- 12V emergency power unit (EPU) with 30 minute run time, capable of
stowing the ladder in the event of a power loss
- High idle is controlled by the microprocessor to automatically
adjust engine rpm to load condition
- Three-speed aerial control switch
CONTROL STATIONS
- Wireless remote control aerial operation (optional)
- Lower control station, rear compartment, centrally located
- Turntable control station
- Additional aerial controls available at aerial tip and pump panel
AERIAL WATERWAY
- Water swivel 5 inch capable of 360 degree rotation
- Telescoping anodized aluminum waterway capable of 1,500 gpm
- 5.5" dia. base waterway pipe
- 5" swivel capable of operating between -8 degrees and up to 75
degrees
- A 250 psi pressure relief valve located below the torque box
- Aerial monitor (electric), Akron self-stowing monitor (standard.)
- Water flow monitored by the aerial microprocessor
- 5" inlet to the aerial waterway
COMMUNICATION SYSTEM
- Atkinson communication system between the tip of the ladder and the
turntable console, with optional third station at pump panel
- Master control at the turntable with push button talk and volume
control
- Self contained "hand-off' speaker/mic at the tip of the ladder
ELECTRICAL SYSTEM
- Electrical swivel capable of 360 degrees with 36 collector rings,
each capable of 20 amps
- 110V electrical system, one (1) 20 amp NEMA L5-20, 3-prong water
proof receptacles at tip of ladder (optional)
- Four (4) 12V unity lights standard, two (2) at tip, two (2) at base
PUMP AND PUMPHOUSES
- A midship pumphouse, centered in the frame, rear of the aerial
turntable
- A driveline driven midship pump, Hale 8FG, single stage (NFPA 2000
gpm rating)
- Piping system - stainless steel
- Valves-Akron standard (Elkhart optional)
- Pump pressure governor standard (option for a discharge relief valve
or TPM)
- Valves are electric controlled
AERIAL BODY
- Compartmentation fabricated from .125" 5052 aluminum with a
tensile strength of 38,000 psi
- Side compartments integral assembly with the rear fender
- Neoprene elastomer isolators will 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
- 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.
