All correspondence must be made through the Vendor Portal. Specifications include, but are not limited to: These specifications contemplate the furnishing and delivery of one NEW ALL-WHEEL DRIVE HEAVY DUTY SINGLE ENGINE CAB FORWARD CHASSIS WITH A FRONT MOUNTED ROTARY SNOW BLOWER with a minimum 57,000 lb GVW rating.; CHASSIS: The chassis shall be designed to permit easy and safe mounting and dismounting of the unit for operators and service personnel. Grab bars shall be installed as required for safe mounting and dismounting by personnel following standards of three-point contact during all mount and dismount activities. This shall include a minimum one-inch diameter vertical grab bar behind each door. The inside of each door shall include a minimum one-foot grab handle positioned under the window. It shall be made of at least one-inch diameter material, round only (no sharp edges or corners) for safety. All sheet metal, cowling, steps and fenders shall be free of sharp edges and protrusions, and include ample supports and bracing to prevent distortion and cracking. All steps or walkways shall be raised lug or expanded metal type construction.; The engine access cover shall be a tilting type with spring assist system pivot toward the rear of the vehicle. Two guides shall be mounted below the leading edge of the hood one left and one right to self align hood as it lowers. Attaching device shall secure the hood in lower position.; COOLING SYSTEM: The cooling system shall consist of a HEAVY DUTY radiator and engine air charge cooler assembly capable of maintain the engine manufacturer recommendations in all conditions. The charge air cooler (CAC) shall be mounted above the coolant radiator core to optimize airflow and reduce the opportunity to collect snow and other debris between the cooling cores. The coolant flow shall be vertical for maximum cooling with the tanks, and side members bolted together to form a rigid frame. The tanks shall be made of aluminum and the core shall be constructed of aluminum bar and plate. Sturdy support between radiator and frame, complete with rubber vibration isolating rubber are required. There shall be a support bracket on top of the radiator, providing stability for the cooling package.; A hydrostatic transmission cooler shall be integrally with the radiator coolant. A thermostatically controlled, air operated disconnect type suction fan shall be provided. Radiator shroud is required to properly direct airflow through the cooling system. An engine mounted fan ring is required and shall attach to the cooling system radiator and charge air cooler through a flexible rubber material. Normal operational engine movement shall not put undue stresses into the cooling system radiator or charge air cooler. The engine cooling system shall be filled with permanent long-life type antifreeze protecting the system to -37 degrees F. Silicone radiator and heater hoses shall be provided.; FUEL SYSTEM: Twin fuel tanks shall have a minimum total capacity of 250 gallons. The tanks shall be constructed of heavy gauge steel and be properly fastened to the frame. A four-inch diameter 45° filler neck with chain connected cap and tank drain plugs shall be provided. Fuel tanks shall be interconnected, single side fuel fill, 1.5 inch with shutoff valves at each end. An engine manufacturer fuel/water separator equipped with transparent bowl and an integrated drain valve shall be installed in the supply line to each Diesel engine. Tanks shall be equipped with ¼ inch steel plate to protect against incidental contact while edge blowing. The fuel tanks shall be located between the front and rear axles to prevent in operation (blower head down) reduction of front wheels traction and steering when tanks are full. All tanks shall meet all requirements for FHWA and FMCSA regulation 393.67 for side mount application. Manufacturer certification is required in the bid package.; PROPULSION POWER TRAIN: The propulsion power train shall incorporate a hydrostatic transmission and two-speed transfer located between the front and rear axle. Both shall permit to operate the vehicle in full power from 0 to top speed not less than 40 MPH without overheating. The transmission shall allow a ground speed in first gear lower than one MPH at engine governed RPM.; Transmission shall be hydrostatically driven, infinitely variable and capable of propelling the snow blower during continuous operation while meeting the snow removal requirements while climbing up to an 12% grade. It shall be equipped with hydrostatic oil cooler.; Hydrostatic transmission power capability shall be not less than 300 hp to be used in travel mode. The transmission power must be certified by calculations signed by engineers to ensure stated capability. Certification and proof hydrostatic transmission power capability are required in the bid package.
