DEVIATIONS FROM THE SPECIFICATIONS FOR ONE SINGLE AXLE LIGHTNING <br />LOADER <br />CITY OF SOUTH BEND <br />-Page 12- Boom rotation is accomplished by direct mounted hydraulic swing drive <br />motor and planetary gearbox and clewing ring bearing. The pedestal has <br />mechanical stops welded into position to provide 270 degrees of boom rotation. <br />Torque rating is 250,000 inch pounds. <br />-The trash bucket is actuated by using two cylinders for tighter "bite". The bucket <br />has high strength tempered steel replaceable cutting edges. <br />-Page 13-We exceed specification for the pump and cylinders. Pac Mac uses a <br />tandem pump which provides "multiple function control" to the loader. This <br />system eliminates orifice fittings used for speed control thus reducing heat <br />generation. Specification calls for cylinders with aluminum pistons. Pac mac <br />utilizes ductile iron pistons. <br />-Grapple unit will be operated by joystick not a bank of rods and levers. The same <br />joystick operation as the last Pac Mac grapple South Bend purchased. <br />-Pac Mac meets intent using AR450 steel for walls and body. <br />-Pac Mac uses twin telescopic 5" main bore cylinders mounted outboard of the <br />chassis frame rails for greater stability. Lift capacity is 15 tons and the dump angle <br />is 45 degrees. <br />-Page 14-Body is painted black. Can be painted green for additional cost <br />
