Specifications include, but are not limited to: To be 3/16" thick and 60 " high at the ends and tapering to approximately 46" at the center, The ends of the moldboard to be squared. To be smooth formed with integral extension similar to moldboard contour. (see attached drawing 1 of 9 ) Moldboard not to be press broken. May have a 22" mailbox cutout on both ends of top of moldboard. (To be discussed at paper pilot). To have ½" thick by 12" wide, 4 cord minimum rubber belting shield. Rubber shield is to be bolted to moldboard in a down position, with reinforcement bar across the front for strength. Bars strong enough not to bend in normal operation of plow. (This will be reviewed at paper pilot review prior to manufacturing pilot plow). To have 6 minimum, one-piece ribs, (no weld joints) and run from the top to the bottom of moldboard. Each rib will be approximately 4" wide at the bottom and taper to 2-1/2" at the top by ½" thick steel. Ribs to have continuous weld on both sides, to moldboard. To have a minimum of 3 horizontal stiffeners, running the full length of moldboard and spaced at an equal distance from bottom edge of plow and the top edge. Stiffeners to be 2" x 2" x 3/8" angle with angle legs welded continuously to moldboard and ribs. Using a "Z" Design attaching bottom angle to moldboard, angle to be 4" x 4" x ½". Both flange edges of angle to be welded continuously to back side of moldboard. Attach a ½" x 4" flat-bar under the angle on moldboard with continuously welds. Gussets are to be welded to bottom side of the angle, and the flat-bar every 12 to 18. CUTTING EDGES: Shall be furnished by UDOT and installed after delivery. SAFETY TRIP: Shall have two single heavy compression trip springs. Springs shall have provisions for adjustment of cutting angle that includes 12 degrees to 24 degrees back from vertical. Springs to have enough strength to hold plow at position within 1 degree from adjusted setting when full weight of plow is on edges and pushed forward. 6 inch diameter with at least 150.0 resistance. To have rubber stops to stop the plow from full tripping. PUSH BEAM: Push beam to be 4’ x 4” x 3/8” square tubing. To be long enough to fasten to at least five each of the vertical ribs. The beam shall be attached to the moldboard at a minimum of 5 places, two of which are at the ends of the beam. These attachments shall be made on the ribs of the moldboard. Ribs to be reinforced at attached points. No holes in square tubing for any mounting purposes. Build up attachment points of the push beam to moldboard, and the trip springs to moldboard, such that the vertical ribs are 1” thick around drilled holes. Extra plates required are welded solid. REVERSING FRAME: Frame and reversing circle to constructed of 4” x 4” x 3/4” angle. ( see attached drawing 2 of 8) LIFT HARDWARE: Plow lift to be a level lift of manufactures design. (chains preferred) Video or visual demonstration to be approved by the Department of Transportation before bid is awarded. To have ¾” bolt through 2 center ribs, or a ¾” clevis, if there is only one rib in the center, (6” to 8” from the top center of plow) for handling plow during repair work.
