Electrical System: <br />Electrical system shall be 24 V, negative ground system, using 12 V, lead -acid, wet cell batteries <br />8D, not less than 1155 CCA at 0 degrees Fahrenheit. Alternator shall not be less than 190 <br />amperes minimum -rated capacity. <br />Hydraulic stem: <br />Hydraulic system shall have an operating capacity of a 90 gal (340.7 L). Tank shall include a <br />filtration method of (2) in -tank return filters with suction strainer. Tub drive shall have a <br />dedicated circuit, load -sense, pressure -compensated pump producing up to 22.1 gpm (83.7 <br />L/min). Implement circuit shall use load -sense, pressure -compensated pump providing up to <br />20.7 gpm (78.4 L/min). Loader hydraulic shall consist of load -sense, pressure -compensated <br />pump with flow capabilities of up to 54.2 gpm (205.2 L/min). <br />Clutch: <br />Unit shall be equipped with a microprocessor -controlled, hydraulically actuated, PT Tech dry <br />clutch, with built-in torque limiting capabilities. <br />Axle: <br />Unit shall be a triple -axle, over slung spring suspension, all steel construction trailer rated at no <br />less than 20,000 lb (9071.8 kg) per axle. Shall be a 2" (5.1 cm) replaceable kingpin. Unit shall <br />also be air actuated with spring supplied park brakes and with <br />Hammermill: <br />Cutting mill shall be drum -type design. Hammermill dram shall have a tip diameter of 29" (73.7 <br />cm) and cutting width of 44" (111.8 cm) with reversible drum skin and replaceable end -caps. <br />The hammermill drum assembly shall contain 7 hammers and 14 tips. <br />Tub: <br />Tub shall have a minimum of 7.8' (2.4) inside diameter with a fixed flare design measuring a <br />maximum of 12.3' (3.7 m) at the top of flare opening. Minimum depth of the tub shall be 5. V <br />(1.5 m). <br />Tub base shall be flared out, allowing cutters to pass along the tub wall reducing material <br />bridging in the tub. Tub wall shall be constructed of a minimum of .25" (6.4 mm) TI steel with <br />four tub agitators welded vertically on the tub wall to help direct material over the hammermill. <br />Tub floor is 3/8" (1 cm) thick T1 steel. <br />Rotation and speed of the tub shall be variable from 0-10 rpm. Tub shall be raised and lowered <br />with a hydraulic cylinder and have pressure -operated check valves and include a mechanical tub <br />table support. Tub table lift shall be interlocked to disable the tub tilt function if hammermill <br />rotation is detected. <br />11 <br />
