The augers must be counter rotating to help prevent bridging of material. Each auger is driven at the rear by a 24.7 CIR hydraulic motor. 1
SPECIFICATIONS ADDENDUM MEETS SPECIFICATIONS? Gearcase shall be coupled to the end of the auger shaft via a 7/8” cross bolt. Auger shaft connect at front with a 2” 2 bolt flange bearing Auger shafts utilize a polyurethane bushing at both ends of each auger to eliminate seizing and ensure ease of maintenance. Hydraulic inter-lock auger shut-off system to shut augers down when cover grates are opened—interlock plumbed at factory 3/8” rod on 3/8” rod top grate screens with anti-freeze hinges are required equipment with auger conveyor v-box units. Extend grease tubes to rear for front auger bearings. 3. 304 STAINLESS STEEL DIRECTCAST SPINNER ASSEMBLY Task-Force shall be equipped with the Direct Cast spinner option. Direct cast spinner system shall be capable of being adjusted electronically in the cab to spread from 1 lane left, center, or right; 2 lanes left or right; or up to 3 lanes at one time. The Direct Cast will utilize a traditional upper chute weldment with (4) position height adjustment. Upper chute shall be constructed fully of 304 grade stainless steel. The material will then enter the focus chute which is constructed of 304 grade stainless steel. The rear side of the focusing chute shall have (2) nozzles which provide capability to apply liquid to the granular product prior to entering the spinner assembly for discharge. The focusing chute shall mount to the spinner disc assembly via a pivoting collar. The collar shall allow the spinner assembly to rotate left and right. Pivoting of the 304ss spinner assembly shall be achieved through a single 1.5-6.5, 1.0 Double acting cylinder. The pivoting cylinder shall have the capability to accept a linear transducer which will provide feedback to the in-cab controller on current position. The pivoting cylinder and transducer shall be designed so the transducer can be replaced without the need to the cylinder being replaced as well. The Direct Cast spinner disc shall be driven by a 4-bolt 2.8 CIR hydraulic motor. Spinner motor shall have an integral sensor capable of providing spinner disc feedback to the in-cab console.

SPECIFICATIONS ADDENDUM MEETS SPECIFICATIONS? The spinner disc shall be constructed of stainless steel with stainless steel fins. Fins shall be in a counter clockwise rotation. Diameter of disc shall be 24”. The spinner disc shall be of a minimum of 90 durometer urethane. 4. PAINT: All stainless surfaces are to be cleaned with an acid solution to remove oil residue and weld discoloration Non-stainless steel parts to be painted black 304 stainless steel components are unpainted 5. REAR LADDER AND REAR CAMERA SAFETY SYSTEM Install stainless steel rear ladder, full color rear view camera system with color monitor, lens wash, automatic infrared mode for night operation, the complete system built to MIL SPEC standards. 6. HYDRAULIC PRE-WETTING SYSTEM MINIMUM REQUIREMENTS All components are mounted in a sealed, corrosion resistant, molded fiberglass cover & housing with stainless hinge Hydraulic drive motor is 1.21 CIR geroler type. Liquid pump is a 10.5 GPM gear type of corrosion resistant materials with carbon graphite bearings. All tubing is stainless steel with plated fittings. (Flexible hoses not acceptable.) A 20 mesh suction strainer shall be installed prior to brass liquid pump. An in-line turbine style liquid flow meter rated of .5 to 5 GPM shall provide liquid flow information to the Hydraulic Control System for precise gal/ton metering. Pre-wet flow-meter shall have external pickup. METERING ORIFICE: Variable displacement orifice provides an extended range of material outputs located in spinner chute. 2 variable displacement orifices 22” wide, vented internal at top of spinner chute. LIQUID ANTI-ICING SYSTEM: System shall be capable of dispensing liquid De-Icers at a rate of 60 gallons per lane mile at 60 mph.

SPECIFICATIONS ADDENDUM MEETS SPECIFICATIONS? Spreader shall have a provision for a stainless steel liquid injection tube which is to be located on the underside of the inverted vee. The injection tube will provide liquid which will be agitated by the spreader augers to create a salt slurry mixture. The injection tube shall be capable of saturating the dry material with up to 20% liquid by weight. The liquid for the slurry generation process shall come from the liquid prewet system. There shall be a ball valve to control flow from the prewet to either the slurry injection line or to the Direct Cast spinner prewet nozzles. RESERVOIR: (2) 400 gallon x .375” wall polyurethane liquid tanks installed each side, for a total liquid capacity of 800 gallons. 400 gallon tanks include sump for complete drainage, minimizes pump cavitations. Gallon markings shall be provided on one end of the tank. Corrosion resistant shut off valves. Reservoir tank is angle formed to allow for mounting on the side of a slip-in v-box Supplied with bulk tank fill quick couplings. Internal baffles are molded into tank & designed to wrap around vertical side braces of spreader for increased capacity The system must be capable of self-loading liquids from a ground based tank or mobile nurse tank. LIQUID PUMP/ VALVES/PLUMBING The liquid chemical pump must be a 210 gpm centrifugal pump with 2” suction and 1-1/2” pressure ports. The hydraulic motor shall be integral with liquid pump. The hydraulic motor will require no more than 13 gpm @ 2100 psi, and must be capable of working on fixed gear pump systems or load sensing systems. Replaceable screen line strainer. Anti-Ice Flow meter shall be Polypropylene manifold type w/ external pick up.
