Specifications include, but are not limited to: It is the purpose of this specification to describe a new, and of the manufacturer's latest current production model and design, front mount snowblower, and heavy-duty single-engine, 4X4, all-wheel steer chassis with a forward-mounted cab. Snowblower shall be capable of 3,000 TPH minimum @ 100 ft. Min. Casting distance at a speed of 11 MPH. ; The chassis shall have a minimum 38,000 pound GVW rating at the ground and an approximate wheelbase of 95-120 inches. The total engine horsepower on board shall be 475 HP minimum. The configuration shall be front-mounted attachment, forward-mounted cab design with near center steering, and a rear-mounted engine.; This snow removal vehicle shall be designed for one-man operation and used up to 28 MPH in transport and up to 11 mph during snow removal operations. The design of this unit shall ensure positive tire-to-ground tractive effort while clearing snow. The unit shall have a net minimum cutting width of 102 inches.; Unit is to comply with requirements of FAA Advisory Circular #150/5220-20 including all changes and updates. This specification will supersede the circular. ; 201.1 Engine: 201.1.1 (*) Diesel, water-cooled, four-cycle, 11.8-liter minimum displacement, electronically controlled, 475 SAE gross horsepower minimum, 1,650 pound-foot torque: minimum. Not to exceed 2,100 RPM. ; 201.1.2 Engine to be mounted to the rear of chassis for unit balance and to allow for minimum noise injection into the cab.; 201.1.3 Governor will be of the correct type to control and limit engine speeds as recommended by the engine, driveline, and power train component manufacturers, for its intended use in this vehicle.; 201.1.4 To be equipped with an electronic high idle circuit, to maintain approximately 1,200 RPM (for warm-up purposes). Cable control is not acceptable.; 201.1.5 The engine shall meet EPA emission requirements as per AIP. ; 201.2 To be equipped with the manufacturer's latest electronic controls for fuel injection and engine management including an automatic shutdown system with manual override and an electrical connector for diagnostics.; 201.3 Engine Air Intake System: Must have a two-stage (dual element) air cleaner with cyclonic type pre-cleaner and restriction indicator.; 201.4 Engine Exhaust System: Exhaust system to be designed to prevent rain, snow, or slush from entering the exhaust system. Exhaust piping to be located away from the cab providing maximum visibility and being heat shielded if vulnerable to maintenance personnel.; 201.5 Engine Cooling System: 201.5.1 The cooling system shall consist of a charge air cooler, engine coolant radiator, and hydraulic system cooler designed for maximum cooling; to be heavy-duty construction. The tanks and core shall be constructed of aluminum with side members welded together to form a rigid frame. ; 201.5.2 The radiator and cooler assembly shall be mounted with vibration isolators. ; 201.5.3 The hydraulic fluid cooler shall have a low-temperature bypass to allow rapid warm-up of the hydraulic and hydrostatic system. ; 201.5.4 Coolant to be extended life type antifreeze, affording protection to -60 ℉. The coolant shall be DELO Extended Life coolant, or compatible.; 201.5.5 Drain cock(s) will be provided at the low point(s) of the cooling system providing maximum drainage.; 201.5.6 Safe and easy access to radiator fill shall be provided (handrails with built-on ladder if necessary).; 201.5.7 Engine coolant level sight gauge, easily seen.
