(Body cont'd) <br />I . A hydraulically actuated packer traversing a minimum of 83-1/2", from YES/NO <br />the front head, shall clear the hopper of material with a maximum cycle <br />time of twenty-six (26) seconds. <br />2. The lower packing panel face will be a minimum 3/16" AR400 abrasion XJL <br />IINO <br />resistant plat steel with typical 184,0�00 PSI tensile strength and 145,000 PSI <br />yield strength. The upper vertical face will be a minimum 7 gauge, 80�,000 <br />PSI typical yield. The packer will be reinforced with a combination of <br />structural members for maximum rigidity. <br />3. Packing mechanism guide rails: <br />a. The hopper zone packer guide rails (2) in the side of the body shall be YES/NO <br />comprised of 3/8" 50,00�O PSI typical yield structural angle welded to <br />3-1/2" x 1/4" ASTM A500 Grade B structural tubing on each side of <br />body, The structural tubing shall be of a continuous piece the full <br />interior length of the hopper, 128" long. <br />b�. Abrasion resistant wear bars, AR500 abrasion resistant with typical YESNO <br />184,000 PSI tensile strength and 145,000 PSI yield strength x 500 BHN, <br />shall be clad to the hopper zone guide rails, each side, in the following <br />manner: <br />a. Bottom horizontal track wear bar shall be 1/4" thick x 3-1/2" wide <br />'YESNO <br />and located 3-1/2" above floor at comer. <br />b. Top horizontal track wear bar shall be 1/4" thick x 2-1/2" wide. <br />YES/NO <br />c. Outer vertical track wear bar shall be 1/4" thick x 2-1/2" wide. <br />�LESNO <br />c. The ejection zone guide rails shall be 3/8" 50,000 PSI typical yield <br />YESINO <br />structural angle welded to the full length 3-1/2" x 3-1/2" x 3/16" AS,TM <br />A50�O Grade B structural tube. A 1/4" x 2-1/2" HRS, wear bar shall be <br />welded to the vertical and undersides surface of the guide rail assembly. <br />The top wear surface shall be clad with 1/4" x 3-1/2 H.R.S, steel. <br />d. The packer panel shall be guided on each side of the body with 3" x 6" <br />3NO <br />JE <br />x 1/4" ASTM A500 Grade B structural tubing clad with AR500 abrasion <br />resistant with typical 184,000 PSI tensile strength and 145,0�00 PSI yield <br />strength wear bars in the following manner: <br />a. Bottom horizontal packer panel wear bar shall be 3/8" thick x 3," wide <br />LESNO <br />x 4 1 " long. <br />b. Top horizontal packer panel wear bar shall be 1/4" thick x 3" wide <br />YES/NO <br />x 41 " long. <br />c. Two (2) vertical packer panel wear bars, located below the structural <br />LESNO <br />tubing, shall be 1/4" thick x 2" wide x 18" long. <br />4. Bolt -on lugs: <br />a. The packer panel shall be provided with bolt-o,n lugs for eachof the two <br />YESNO <br />(2) packing,eylinders. The cylinders shall be attached to the packer panel <br />lugs via two inch (2") diameter pins. Cylinder removal may be <br />accomplished by either pulling the pins or by removing the entire bolt -on <br />lugs. The lugs shall be attached to the packing panel with six (6) 1/4" <br />diameter bolts for each lug assembly. <br />b. The body front head shall also be provided with b�olt-on lugs for packing <br />YESNO <br />cylinders. The lugs shall retain cylinder pins with four (4) 3/4" diameter <br />bolts. <br />14 <br />
