Completed unit shall be capable of passing ANSI/SIA A92.2-2001 stability test when mounted on a cab/chassis of at least 14,500 GVWR.  Use of counterweight, torsion bar or outriggers may be requied for stability.  



Operating pressure shall be a maximum of 2500 PSI.  Operating oil volume shall be 2.5 GPM for lift operation.  Open center type hydrauic system shall be used.  Unit shall be equipped with a 10-microm filter in the return line and 100-mesh screnn at the suctin port of the 10-gallon oil reservoir.  System pressure relief of be integral to the lower control valve. 

Double acting hydraulic cylinders equipped with an intergral holding valve shall provide boom motion.  Upper boom to articulate through use of a hydraulic cylinder attached directly to lower boom and four bar linkage to upper boom cylinders shall be identical for ease of service.  

All hydraulic adapters must be machined form forgings.  Brazed hydraulic adapters are not acceptable.  Hydraulic hose to be non-conductive Parker 518C with permanent crimped on fittings.  Reusable fittings can be used for field repair. 



The pedestal shall be 0.25 in. steel welded into a rectangular structure with a 1.0 in. top plate. The hydraulic reservoirwill be a seperate component mounted inside the pedestal for protection.  The reservoir will include a sight glass indicating oil leve nd temperature.  Hydraulic reservoirs to be constructed from steel and powder coated for maximum cooling and protection from corrosion.  Hydraulic reservoirs integral to the pedestal are not acceptable.  

The turret assembly will be a welded assembly with 0.50 sides and 0.75 in. base plate. The turret and pedestal will be fastened to the rotation system with 0.63 in. diameter grade 5 hex head cap screws tightened to a specified torque.  Rotation cap screws to be installed with a thread locking liquid to prevent loosening. 

Platform shall be one piece fiberglass, 24 in. X 24 in X 42 in. with a molded step at 90° to the rear of the mounting ribs. A non-skid surface will be bonded into the step surface.  Self adhesive non-skid strips are not acceptable.  

All pivot pins shall have a minimum tensile strength of 100,000 PSI, Pins shall be zinc plated and have non-lube bearings at all points of boom movement.


The aerial device shall be a non-overcenter articulating type. The lower boom and steel section of the upper boom is to be fabricated from 5 in. X 7 in. high strength/low allow steel tubing with a minimum yield of 70,000 PSI.  The lower boom shall operate from -5° to a +95°.  The upper boom shall travel up tp 160° relative to the lower boom. 

The mechanical leveling system includes #60 roller chain, 0.50 in. steel rods in the lower boom and 0.50 in. fiberglass rods in the upper boom.  Leveling and tension adjustment is at the knuckle and includes hex turnbuckles for ease of actuation.  Hose guides to be included to isolate the leveling system from the hoses at the elbow and turret.  Exterior mounted leveling systems and/or systems using leveling cables are not acceptable. 

A section of the upper boom shall be constructed of filament wound fiberglass reinforced plastic using epoxy resin and oven cured for consistent strength. Hand laid up booms or catalyst cured polyesterresins are not acceptable.  The upper boom shall be dielectrically tested and certified to meet ANSI A92.2-2001 for Category C, 46KV and below.


The pedestal base shall be mounted on cross members undeneath the body floor.  The body floor must be removed to allow the base to be bolted directly to the cross members and isolate it from the body floor.  Mounting that attaches to or sandwiches the floor is unacceptable.  

Platform access step from the body load space is required.  A boom restwith a rubber pad molded to a steel plate and ratchet tie down strap shall be mounted in the body load space. Rubber pads not molded to a steel plate are unaccetoable.  A single strap must secure both upper and lower booms.  


Rotation shall be accomplished through use of a "shear ball" bearing and worm gear drive system built as an integral component.  The worm gear is self-locking and "hourglass" shaped for multiple points of contact beween the worm and the helical gear teeth of the rotation bearing.  Rotation shall be limited to 540° non-continuous by means of a mechanical stop.  Electric or hydraulic rotation stops are not acceptable.  Hydraulics swivels must be installed on the pressure and return lines to prevent twisting of the hoses. 

The rotation system must be set at the factory and not require any field adjustment.  Seperate right angle drive gearboxes that require periodic adjustment are unacceptable.  The worm shaft shall have exposed hexagonal end for manual rotation.  


Both upper and lower controls shall be individual lever manual hydraulic valves for "Full Feathering" operation with any power source. The upper controls must be located between the boom and platform for maximum protection from damage. The lower controls shall be capable of overriding the upper controls.  Emergency stop is provided as an integral part of the upper controls. Monoblock valves must be used to minimize leakage points. 


May be equipped with either a 24" X 24 X 42" or 24" X 30 X 42" fiberglass step over bucket or a 30" X 30" X 42" aluminum platform with duck chain opening. 


A holding valve shall lock boom cylinders in position in the event of hydraulic hose failure. 

Unit shall be covered with a nylon sleeve in areas of abrasion.

Controls at pedestal shall override controls at bucket in the event of operator becoming incapitated.  

Unit shall have an automatic hydraulic limit to prevent upper boom from traveling overcenter. 

Locking devices shall be incorporated into the upper controls per ANSI/SIA A92.2-2001. An emergency stop control shall be integrated into the upper control valve at the platform.  

A fall protection anchor must be attached to the upper boom. Anchors attached to the platform or platform support ar not acceptable.  A body harness and shack absorbing lanyard must be provided for fall protection.  



Continuous and unrestricted boom rotation is provided by a combination hydraulic and electric rotary joint mounted in the turret. The rotaty joint provides passages for oil and electric signals from the operator's platform.  


The lower boom shall include an insert made form filament wound fiberglass reinforced plastic using oven cured epoxy resin for consistent strength.  Hand laid up sections or catalyst cured polyster resins are not acceptable.  Minimum insulation gap to be 8 inches.  The lower boom shall be dielectrically tested and certified t meet ANSI A92.2-2001.


A mechanical hinge and latch system is provided for tilting the operator's platform for resue or cleanoutl.  A serperate latch system is provided for tilting the operator's platform for rescue or cleanout.  A seperate locking pin prevents inadvertent operation.


The single stick control provides lower and upper boom functions along with boom rotation from one control.  When depressed, the safety trigger under the single stick provides hydraulic flow for the boom operations.  No seperate emergency lowering system shall be at the upper and lower controls.


With the engine belt drive and PTO options, a seperate emergency lowering system will be powdered by a 12V DC motor locatedin the pedestal.  Controls to actuate the emergcency lowering system shall be at the upper and lower controls.

With the electric power and dual power source options, the operator can utilize the chassis battery for emergency lowering.  Teh same 12 DVC motor is used for normal and emergency operation.  


Hydraulic power shall be provided by an engine accessory belt drive powered pump of sufficient size to furnish 2.5 GPM at engine idle. Engine stop/start is provided for upper controls.  

Hydraulic power shall be provided by a transmission mounted PTO and pump of sufficient size to furnish 2.5 GPM at engine idle. Engine stop/start is provided for upper controls.
