105’ HD Ladder Features
• Four (4) section, telescoping steel ladder constructed of high strength steel, certified to 70,000 psi
• Aerial device mounted over the rear axle, on a torque box sub-weldment w/front and rear stabilizers with the ability to short-jack
• Bolt-on egress with full 500 lb. or optional 750 lb. rating
• Modular construction allows for easy component replacement if damage were to occur

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
• Fold down steps standard at tip
• Rungs are sheathed with an aggressive composite luminescent rung covers to increase visibility during egress and do not need electrical connections or amp draw
• Extension and retraction motion by dual hydraulic powered cylinders and cable pulley system
• Rotation motion through a 46.00" swing bearing/spur gear, driven by one (1) planetary hydraulic motor
• Elevation motion through (2) double acting, lift cylinders (5 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

Turntable Deck
• 95” wide x 84.50 long turntable is constructed of a 1.00” thick deck, coated with a non-skid, chemical-resistant material. 
• Pull-out, drop-down steps provide easy access to the turntable from rear body stair wells, one (1) each side of the truck
• Stairs are lit by (2) 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 direct hydraulic, fully proportionate
• 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 38 gallons
• Relief valve set at 3150 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:

Control Stations:
1. Lower control stations for the stabilizers are located on each side of the body
2. Turntable control station
3. Additional aerial controls available at aerial tip and pump panel

Aerial Waterway
• Water swivel 5.00 inch capable of 360 degree rotation
• Telescoping anodized aluminum waterway capable of 1000 gpm
• 5.00" dia. base waterway pipe
• 5.00" swivel capable of operating between -5 degrees and up to 75 degrees
• A 250 psi pressure relief valve located below the torque box
• Aerial monitor (electric), capable of 1000 gpm, Akron self-stowing monitor (standard)
• 5.00" rear inlet to the aerial waterway located on driver’s side for improved access to ladder storage compartment.

Communication System
• Atkinson communication system between the aerial tip 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 28 collector rings, each capable of 20 amps
• 110V electrical system, one (1) 20 amp NEMA L5-20, 3-prong water proof receptacle at tip of aerial (optional)
• Four (4) 12V unity lights standard, two at tip, two at base

Pump and Pumphouse
• A midship pumphouse, centered in the frame, ahead of body
• Piping system - stainless steel
• 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, Galvaneal steel, or stainless steel
• 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 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
• Galvaneal 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 w/lifetime warranty (available in satin or painted finish) .
• Handrails are Pierce's exclusive "cross knurled" design to reduce hand slippage.
