SPECIFICATIONS for Hydrostatically Driven Front Wheel Drive Self- Propelled ChipSpreader

It is the intent of these specifications to describe a hydrostatically driven, self-propelled Chipspreader in sufficient detail to secure bids on comparable equipment. All Parts not specifically mentioned, which are necessary to provide a complete Chipspreader, shall be included in the bid and shall conform in strength and quality of material and workmanship to what is generally provided to the industry. The unit shall be a current model in standar4d production by the manufacturer.

Any units not conforming to these specifications will be rejected and it will be the responsibility of the manufacturer to conform with all requirements unless deviations have been specifically cited by the bidder and acceptance made on the basis of such deviations.

Function

The self-propelled Chipspreader shall be designed and constructed to apply a uniformly distributed application of cover and seal coat aggregates.

I. POWER TRAIN

ENGINE: Cummins 6 cylinder, turbocharged, diesel engine. Manufacturers maximum rating 260 H P. Includes electric start, alternator, voltage regulator and 12 volt batteries. Engine to have dry type air cleaner, disposable element type oil filter, heavy duty cooling system, cable throttle actuator, control/instrument panel to have lockable cover to prevent accidental starting and pilferage.

HYDROSTATIC DRIVE: Mechanical front wheel drive steer axle, full oscillating 75” wheel track, 20.37:1 gear ratio, 25,000 lb rated, single speed differential. Driven by direct engine bell housing mounted 125 cc hydrostatic pump and 160 cc hydrostatic motor. Rear axle is 25,000 lb rated with 95” wheel track. Infinitely variable speed from 0 to 19.5 M.P.H.

BRAKES: Mechanical front axle has hydraulic internal drum brakes controlled by foot pedal. Rear axle has hydraulic actuated drum brakes, 16 1/2” X 7”. Also includes spring applied hydraulic release fail-safe parking brake in the drive line, automatically applies if hydraulic power is lost.

STEERING: Full hydrostatic power steering from 1.22 cc fixed displacement gear pump, with dedicated flow independent of engine speed.

TIRE & WHEELS: (4) 385/65R 22.5 tires on disc wheels.

II. FRAME ASSEMBLY

The complete power train, diesel engine, hydrostatic pump and motor, front and rear axles, shall be mounted to the lower removable main frame.

Upper removable main frame assembly includes both conveyors, right and left access ladders and walkways. 70 gallon built in hydraulic oil reservoir, 82 gallon diesel fuel tank for engine, rear 4 cubic yard hopper and truck hitch. Complete main frame is 3/16” steel construction.

CONVEYORS: To have heavy duty 24” conveyors belts which are independently activated by electric switches. To be powered by a load sensing 74 cc variable displacement pressure compensated hydraulic pump, high torque 19.0 C.I.R. hydraulic motors with direct drive to head pulley. Electric switches for each conveyor control to have easy access mechanical override. Hooded, adjustable aggregate deflector to be located at head of each conveyor. Troughing idlers to be quick removable type and tail pulley to be adjustable for insuring proper belt alignment.

Electric/hydraulic folding wings on rear receiving hopper.

AUTOMATIC CONVEYOR CONTROL: Automatically starts and stops the conveyor belts to control the aggregate level in the spread hopper. Shall include override control enabling the driver/operator to start and stop the conveyors and each conveyor to have speed adjustments at operator’s station for conveyor and auger functions.

SPREAD HOPPER: Spread width to be from 10-20ft. Struck capacity of hopper to be .2 cubic yard per foot of hopper width. Spread roll to be 6” diameter machine welded heavy wall tubing. Agitator to be 2 ½” tubing and have quick disconnect pin. Each radial gate to have individual, air operated controls. Each gate to have adjustable, reversible wear plates to include

(4) 6” gates each end with 12” gates in center. Spread roll and agitator to be driven by a high torque 12.0 C.I.R. hydraulic motor with quick coupler hose connection.

FRONT HOPPER REJECT SCREEN: A full width rock type screen with 1 ½” openings shall be placed over the top of the spread hopper to retain all oversized materials and foreign objects.

RECEIVING HOPPER: Hopper shall be a minimum of 132 inches wide with a capacity of approximately 4 cubic yards. Hopper to have hydraulically folding paver style wings controlled from the operator’s station. Shall include heavy duty hopper skirting and an adjustable flow gate for each conveyer belt.

TRUCK HITCH: The unit shall be equipped with a positive, self-locking “railroad” type adjustable truck hitch, which can be electrically released from the drivers or operators position. Hitch height to be electrically controlled from drivers seat. The truck hitch shall be the type which will permit holing and unhooking of aggregate trucks without stopping the Chipspreader and be capable of maintaining positive engagement over irregular terrain.

APPLICATION RATE COMPUTER: The Application Rate Computer monitors the actual speed of the Etnyre Chipspreader and varies the gate opening in order to maintain the set application rate in lbs/yards of the selected aggregate, regardless of the speed of the Chipspreader. The computer can store five different aggregate/application rate combinations in its memory.

The present aggregate can be selected together with its application rate at any time. In addition, the application rate can be varied as desired while operating, or a different present combination may be selected at any time.

The computer can also be set to control the Chipspreader’s forward speed for consistent speed when following the distributor. The computer speed sensor replaces the need for radar ground speed system. Computer also monitors fuel level, engine oil pressure, hydraulic oil temperature, engine coolant temperature, hours on engine and miles chipped.

OPERATOR STATION: All controls located to the front for easy access to the spring suspension seat from either right or left side.

III. MISCELLANEUS:

LIGHT PACKAGE: Unit to have headlights, stop and tail lights and turn signals with flasher switch.

FRONT FENDERS: Each side.

HORN: An electric horn shall be furnished.

BACKUP ALARM: An electric backup warning alarm to be furnished.

PAINT: Standard highway yellow

Unit to have one full length walkway with skid resistant surface adjacent to one side of conveyor system. A steel, lockable toolbox shall be mounted under the mail deck.

WARRANTY

One year on material and workmanship. Components manufactured by others shall carry such warranty as is provided by the manufacturer.

Manufacturers descriptive literature, specifications shall be included with the bid and any deviations from these specifications are to be listed.

Successful bidder to furnish parts book(s) and complete operating instructions.
