TRUCKS>AERIAL>SKY-ARM^® PLATFORM

---

The only four-section, 100', articulating aerial ladder platform in the industry. The Sky-Arm articulates a full 60-degrees below grade, making it ideal for water, ravine and ditch rescues.

FEATURES

• Four (4) section, telescoping steel ladder constructed of high strength steel, certified to 80,000 psi with articulating fly and a self-leveling basket
• Aerial device mid-mounted behind the cab to a torque box sub-weldment with front and rear stabilizers
• Modular construction allows for easy component replacement if damage were to occur

LADDER ASSEMBLY

• Ladder sections are trussed vertically and diagonally
• All ladder rungs are welded to each section in two (2) places with k-bracing for rigidity
• Rungs are sheathed with a heavy duty, serrated rubber
• Extension and retraction motion by dual hydraulic powered cylinders and cable pulley system
• Rotation motion through a 48" swing bearing/spur gear, driven by one (1) planetary hydraulic motor
• Elevation motion through (2) double acting, lift cylinders (6 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

PLATFORM BASKET ASSEMBLY

• Basket structure constructed of high strength 6061-T6 aluminum
• Basket shall rotate 28 degrees either side of center
• Basket floor shall be of an open type grating to prevent the accumulation of water
• Front deck 6", 4" on sides
• Rubber bumpers below basket to prevent damage
• Encircled with a safety rail 42" high
• Fully illuminated basket interior
• Two (2) lifting rings below the basket attached directly to the platform frame work
• Control panel mounted on the right side of the basket

TURNTABLE DECK

• Turntable construction is .88" thick 100,000 psi steel covered with aluminum treadplate
• The turntable is 96" wide x 118" long 
• Access to the turntable is from rear 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 

AERIAL DEVICE POWER

• One turntable control station located on driver side
• Aerial controls are electronic over hydraulic 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
• Pressure and return filtration system
• Hydraulic reservoir of 65 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

CONTROL STATIONS

• Lower control station, rear compartment, centrally located
• Turntable control station
• Aerial basket control station

AERIAL WATERWAY

• Water swivel 5 inch capable of 360 degree rotation
• Telescoping anodized aluminum waterway capable of 1,000 gpm
• 5" dia. base waterway pipe
• 5" swivel capable of operating between -6 degrees and up to 75 degrees
• A 250 psi pressure relief valve located below the torque box
• Aerial monitor (electric), capable of 1,000 gpm
• Water flow monitored by digital flowmeter
• 5" rear inlet to the aerial waterway

COMMUNICATION SYSTEM

• Atkinson communication system between the basket 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 basket

ELECTRICAL SYSTEM

• Electrical swivel capable of 360 degrees with 36 collector rings, each capable of 20 amps
• 110V electrical system
• Four (4) 12V unity lights standard, two at the basket, two at base

PUMP AND PUMPHOUSE

• A midship pumphouse, centered in the frame, ahead of body
• Removable pump panels provide access to the pump for maintenance
• 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 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
