Specifications include, but are not limited to: One (1) Trailer-Mounted Spray Injection Patching Machine, with the following minimum specifications: • Emulsion Tank o Size - 250 U.S. gal; 12-inch filler cap for added safety and convenience o Working Pressure - 200 psi @ 500° F pressure relief set from 100-110 psi o Insulation - R-15 rating with a fire-retardant fiber reinforced plastic cover o Heat - Two 1500w radiant heater blankets (120v) with thermostatic control • Compressor o Screw type compressor producing 60cfm @ 100 psi maximum 150 psi • Blower o 450 cfm with 7 psi (14 psi potential) @ 1500 rpm, approx. 42 BHP. Mounted directly off engine flywheel (requires no belts or pulleys). Protective air pop-off valve set at 10 psi. Normal operating temp under 230° F (max 275° F). • Conveyor o Air Conveyor Aggregate Feed Hopper box on patcher receives aggregate via a 5" diameter flex hose from dump truck. Aggregate is injected into the air conveyor system via a low-pressure suction created by a venturi (under the hopper box). Slide gate opens and closes by a 4" stroke air ram controlled through a 12v air solenoid valve activated by a remote switch located at operator control handle. Aggregate 1/4" - 1/2" size is normally used. Machine will run up to 1" aggregate and will allow a 2 1/2" stone to pass through without clogging. Air solenoid valve has manual override for easy servicing. • Aggregate Hose o A 20' long x 1/2" ID hose rated at 2300 psi carries the emulsion to the spray nozzle. Emulsion lines are encased in an insulated line packet to allow for cold weather operation. This line also serves as the clean-up line when patching operations are completed. • Swinging Hose Carrier o Easy Operation - Free travel boom system supports the weight of the aggregate hoses. System allows an 18" working travel radius. All operator controls for throttle and aggregate flow are at the handle. • Clean-Up Line o A 20' long x 1/2" ID hose rated at 2300 psi carries the emulsion to the spray nozzle. Emulsion lines are encased in an insulated line packet to allow for cold weather operation. This line also serves as the clean-up line when patching operations are completed. Clean up takes about 1 quart of liquid. • Mobile Heating System o Engine coolant is routed through a heat exchanger filled with heat exchange oil. The heated oil circulates via a 12v circulation pump throughout the emulsion distribution system, including the emulsion storage tank, hoses, and spray nozzle. Average system temp is 140° F. The total patcher can work effectively down to an ambient temp of 20° F (using proper emulsion for those temperatures). • Emulsion line clean out tank o 15 U.S. gal pressure vessel rated at 200 psi @ 450° F pressure relief set at 175 psi
