A?'cte MN Anchors,® , �nr. INSTALLATION NU-CONCEPT ANCHOR CLASS 3&4 Patent Pending The Nu-Concept Anchor combines a patented elongated hole in the tension head with a stabilizing and compaction cap. When combined with a grade 5 bolt, the anchor will rotate in all directions allowing adjustment to uneven terrain. Under load conditions the cap, rotates down ward in the direction of the pull, causing a double compaction of the soil and laterally restricts movement of anchor through the soil. , Attach stabilizer/compaction cap to the tension head of the anchor. This is done by sliding the cap over the top of the tension head, aligning 9/32" holes in cap with 1/4" elongated hole in tension head. Insert 1/4" x 2-1/4", grade 5 bolt (included). Hand tighten. Cap must be installed at anytime prior to ground contact. Figure A Figure B See Cap Figure A and Tension Head Figure B. (TOP) 0 Class 3 - 4430 NU 3/4 (BOTTOM) Class 4 - 4636 NU 7/8 II The Drive Machine is started and the anchor is turned into the ground to a point where the bottom of the tension head is at or slightly below ground level. This insures Stabilizer/Compacting .1. / Head maximum soil compression by the cap. Figure C See Figure C. Engineered to allow ground anchor to be installed at a slight back angle of15° Class 3 - 4430 NU 3/4 Class 4 - 4636 NU 7/8 110 Stabilizer/Compacting Head III, Anchor is pre-loaded. Pre-load causes the cap to rotate downward in the Figure D direction of pull, further compacting the soil and presenting a larger surface area, resisting both horizontal and vertical movement, See Figure D. When used with rigid support tubes, rather than strap systems, pre-loading is not required. Note: A special adapter is available to insure against tension head and bolt damage. 67 1 6. �v
