Boom design shall contain supports (arms) capable of operating and supporting the aggregate hose(s) in a safe manner with minimal exertion from the operator.

Operator controls shall be boom mounted to contain asphalt, aggregate, throttle, hydraulic, and horn controls.

The Operating position shall be approximately (four) 4 feet from the material discharge and designed to eliminate material over spray from contacting the operator.

Discharge Nozzle and Coating System:

Asphalt spray shall be capable of a 100% coating of the aggregate prior to discharge.

Unit must be capable of placing up to 3.5 tons of patching material per hour.

The end of the nozzle shall be fitted with an operator controlled, electrically powered heating element to prevent clogging at the nozzle during periods of not being in use.

Compressor:

Unit shall have a working minimum 13.2 CFM, direct drive with governed regulator control and capabilities to piggyback a hydraulic pump.

Operating pressure 100-150 PSI.

Aggregate Delivery System:

Unit shall have a pneumatic venturi eductor that conveys aggregate from hopper, through emulsion spray bath and out the nozzle with no moving parts.

Aggregate hopper shall be bolt on. Able to be replaced in the event of damage from large debris.

Aggregate flow shall be regulated by air actuated slide plate.

Aggregate flow controls shall be located on articulating operator’s boom for fingertip operation.

The top of the aggregate hopper shall be a maximum 36”, measured off the ground with the unit sitting level.

Tailgate Feed:

Unit shall come equipped with gravity trough or auger feeder design to adapt to typical dump truck slip-gate that includes a tapered type trough to feed aggregate directly from tailgate to aggregate hopper.

Blower:

Blower shall be a high volume, direct drive 450 CFM or larger lobe blower.

Blower shall be equipped with heavy duty silencer.

Engine:
