General 1. The unit must be designed and tested to push debris weighing up to 150 lbs. at 20 mph in the deployed (down) position. 2. The unit must be designed and tested to push disabled vehicles when in the stowed position. 3. Host vehicle requirements: Available for Ford, GM, and RAM trucks that are 3/4 -ton and larger. 4. Vehicles not equipped with these options may require replacement front suspension springs to achieve correct load capacity and optimal ride height. 5. HD modular steel construction with powder-coat finish to provide corrosion resistant finish. 6. Powder-coat must be industry standard 2.5 mils in film thickness to conform with AAMA 2603 and salt spray resistance to 2,500 hours. 7. All steel components shall be white metal blasted or equivalent. 8. Dimensions: Wings stowed 95" or less. 9. Wings at half-extension 98" or less. 10. Wings fully deployed 89" or less. 11. Device to host vehicle mounting must include the following: Bolted directly to frame for strength and durability. 12. Vehicle specific mount for a precise fit that allows the blade to be agile in tight spaces, narrow shoulders, and crash scenes. 13. Quick disconnect feature to allow for ease of servicing host vehicle. 14. Integrated heavy-duty bump stops to give added strength and redirect force to vehicle frame when pushing vehicles in stowed position. Control system must contain the following features and specifications: 1. This device must be equipped with a computer-controlled safety deployment limiter to prohibit deployment over 20 mph to limit high-speed impact situations, to ensure the safety of the operator, and reduce the risk of ricocheting objects. 2. Deployment limiter must not restrict the vehicles capability of operating above 20 mph. 3. The touch screen controller/monitor must include one-touch "Deploy" and "Stow" buttons for simplified and safer operation of deployment of the device. 4. The controller will also include manual "Up", "Float down", "Wings Forward", and "Wings back" buttons. 5. The controller/monitor shall automatically dim in low light environments and be equipped with a "Sleep mode" button for additional safety. 6. The controller must have an indicator light to show when the unit is in float mode. 7. The unit must have an in-cab flashing indicator light to alert the driver that the blade is not in the stowed (up) position. 8. The unit must lower with a gravity down, soft stop for smoother operation and decreased wear on the hydraulic system. 9. The unit must float when in the deployed position to follow the contours of the road surface to reduce wear on the unit, avoid damage to road surface, and not alter steering of host vehicle. Moldboard and wings must contain the following features and specifications: 1. 1" thick rubber contact face to protect device during debris removal and to provide additional protection when being used as a push bumper in the stowed position. 2. Must be equipped with a front mounted D-ring with a rating of 4,080 lbs. 3. Hydraulically adjustable wings mounted to left and right of moldboard to contain debris when deployed and to contour to vehicle when stowed. 4. Wings deploy simultaneously with single push-button control. 5. Secured to moldboard with full height 1" hinges with removeable pins and grease fittings. 6. Wings are ~35° from the moldboard when stowed. They travel 75° to their fully deployed position. When fully deployed, they are 40° from the moldboard. These angles have a +/- 5° tolerance. 7. Bolt-on replaceable wear edges. Available in steel or rubber. These are a wear item to prevent damage. 8. Air flow provisions for host vehicle's cooling system. 9. Side wear plates on wings to assist in containing debris. Hydraulic system must contain the following features and specifications: 1. Hydraulic pump be a 12-volt, 2HP motor with pressure rating of 2,000 PSI. 2. System to consist of pump, manifold, and reservoir mounted to the back side of the moldboard, containing approximately 1 gallon of fluid. 3. Two hydraulic lift cylinders and one hydraulic cylinder per wing. 4. Reservoir to be equipped with fill cap and dip stick for easy servicing. 5. 1,200 PSI crossover relief valve to allow fluid to flow safely back to the reservoir from the wing cylinders in case of excess pressure. This prevents the wings from damage and allows them to return to stowed position. Camera system must contain the following features and specifications to allow the operator to see the debris field close to the blade: 1. 170° wide-angle lens infrared camera. 2. 7" touchscreen, 720p HD resolution in-cab monitor. 3. Camera mounted top-center of device to view moldboard blind spot by driver.
