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
cover
- Extension and retraction motion by dual hydraulic powered cylinders
and cable pulley system
- Rotation motion through a 54" swing bearing/spur gear, driven by (2)
planetary hydraulic motor
- Elevation motion through (2) double acting, lift cylinders (8 deg
below horizontal to 75 deg 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

LyfeLatch® door latches
- Basket leveling system design using master-slave, closed-loop hydraulic
cylinder system
- Fully illuminated basket interior
TURNTABLE DECK- 102" wide turntable is constructed of a 1"
thick deck, coated with a non-skid, chemical resistant material

- Pressure and return 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
- Lower control station, rear compartment, centrally located
- Basket control station
- Turntable control station
AERIAL WATERWAY
- Water swivel 5 inch capable of 360 degree rotation
- Telescoping anodized aluminum waterway capable of 2,000 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), capable of 2,000 gpm
- Water flow monitored by the aerial microprocessor
- 5" rear inlet to the aerial waterway
COMMUNICATION SYSTEM
- Atkinson communication system between tip of the ladder and the
turntable console, with optional 3rd 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 located in basket
- Four (4) 12V Collins lights standard, two at tip, two at base
PUMP AND PUMPHOUSE
- A midship pumphouse, centered in the frame, rear of the aerial
turntable
- Suction inlets:
- One 6 inch main on driver's side
- One or two 6-inch main on passenger side
- One 3 inch tank to pump line. Will be air actuated
- Discharge outlets:
- Two 2.5 inch on driver's side
- One 2.5 inch or 3-inch on passenger side
- One 4 inch LDH on passenger side
- Two 2 inch crosslays
- One 1 inch tank fill
- One 4 inch aerial discharge
- No front or rear discharges are available
- Piping system - stainless steel
Valves-Akron standard (Elkhart optional)
Pump pressure governor standard (option for a discharge relief valve
or TPM)
Valve controls - all valves will be 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
