01 <br />3. <br />E <br />(Body cont'd) <br />A hydraulically actuated packer traversing a minimum of 83-1/2", from <br />&0 <br />the front head, shall clear the hopper of material with a maximum cycle <br />time of twenty-six (26) seconds. <br />The lower packing panel face will be a minimum 3/16" AR400 abrasion <br />&40 <br />resistant plat steel with typical 184,000 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 />Packing mechanism guide rails: <br />a. The hopper zone packer guide rails (2) in the side of the body shall be <br />(9/NO <br />comprised of 3/8" 50,000 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 <br />OYE N 0 <br />184,000 PSI tensile strength and 145,000 PSI yield strength x 500 BffN, <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 />&NO <br />and located 3-1/2" above floor at corner. <br />b. Top horizontal track wear bar shall be 1/4" thick x 2-1/2" wide. <br />0 <br />c. Outer vertical track wear bar shall be 1/4" thick x 2-1/2" wide. <br />0 <br />#INNO <br />c. The ejection zone guide rails shall be 3/8" 50,000 PSI typical yield <br />structural angle welded to the full length 3-1/2" x 3-1/2" x 3/16" ASTM <br />A500 Grade B structural tube. A 1/4" x 2-1/2" H.R.S, 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 />1&0 <br />x 1/4" ASTM A500 Grade B structural tubing clad with AR500 abrasion <br />resistant with typical 184,000 PSI tensile strength and 145,000 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(YEV/NO <br />x 41 " long. <br />b. Top horizontal packer panel wear bar shall be 1/4" thick x 3" wide <br />(g/No <br />x 41 " long. <br />c. Two (2) vertical packer panel wear bars, located below the structural <br />CES <br />tubing, shall be 1/4" thick x 2" wide x 18" long. <br />Bolt -on lugs: <br />a. The packer panel shall be provided with bolt -on lugs for each of the two <br />Q <br />(2) packing cylinders. 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)3/4 <br />diameter bolts for each lug assembly. <br />b, The body front head shall also be provided with bolt -on lugs for packing <br />0 <br />cylinders. The lugs shall retain cylinder pins with four (4) 1/4" diameter <br />bolts. <br />14 <br />
