Specifications include, but are not limited to: The purpose of this IFB is to enter into a contract with the lowest responsive and responsible bidder to provide 12-foot Power Reversing Straight Snowplow, with discount from OEM parts and labor rates; MOLDBOARD To be 3/16” thick and 41” high approximately. The ends of the moldboard to be squared. To be smooth formed with integral extension similar to moldboard contour. (see Exhibit A Drawing 1 of 8 ) Moldboard not to be press broken. To 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 the bottom side of the angle, and the flat-bar every 12 to 18 inches. CUTTING EDGES Shall be furnished by UDOT and installed after delivery. 3. SAFETY TRIP 3.1 Shall have two single heavy compression trip springs. 3.2 Springs shall have provisions for adjustment of cutting angle that includes 12 degrees to 24 degrees back from vertical. 3.3 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. (See Exhibit A Drawing 6 of 8) 3.4 To have rubber stops to stop the plow from full tripping. 4. PUSH BEAM 4.1 Push beam to be 4” x 4” x 3/8” square tubing. 4.2 To be long enough to fasten to at least four each of the vertical ribs. 4.3 The beam shall be attached to the moldboard at a minimum of 4 places, two of which are at the end of the beam. These attachments shall be made on the ribs of the moldboard. Ribs to be reinforced at attached points 4.4 No holes in square tubing for any mounting purposes. 4.5 Build up attachment points of the push beam to moldboard, and trip springs to moldboard, such that the vertical ribs are 1” thick around drilled holes. Extra plates required are welded solid.
