Im FIGURE 6-3 6.5.8. All exposed metal on the anchoring system must be coated or galvanized to protect against corrosion. 6.5.9. When fastening wire rope, use a minimum of two clips for a 3/8 -inch wire rope and three clips for a 1/2 -inch wire rope on each termination. See TABLE 6-3 for minimum wire -rope diameter. 6.5.10. Turn back from thimble the exact amount of wire rope specified by the manufacturer of the clips used. 6.5.11. Apply the first clip at a distance from the dead end of the wire rope that is equal to the largest width of the clip used. (See FIGURE 6-4.) 6.5.12. For each clip, apply a U -bolt over the dead end of wire rope. (See FIGURE 6-4.) (Note: Live end rests in saddle.) d 2' Clip Clip 3' Clip Live End Thimble y Loop Dead FIGURE 6-4 6.5.13. When two clips are required, apply the second clip as near the loop or thimble as possible. (See FIGURE 6-4.) 6.5.14. When more than two clips are required, apply the second clip as near the loop or thimble as possible, tum nuts on second clip firmly, but do not tighten initially. (See FIGURE 64.) 6.5.15. When more than two clips are required, space additional clips equally between the first two, take up rope slack, and tighten nuts on each U -bolt evenly. 6.5.16. Tighten all hardware uniformly and follow the manufac- turer's torque specifications. Double-check the tightness once the anchoring system is complete. 6.5.17. If forming a loop in the wire rope, a splice is required for connecting the two ends together. Standard rigging practice for splicing wire rope calls for using twice the number of clips recommended for a single -end termination. Use a minimum of four clips for a 3/8 -inch wire rope and a minimum of six clips for a 1/2 -inch wire rope. Place the rope ends parallel to each other and install the clips as shown in FIGURE 6-5. 15 3/8" Wire Rope f--- Live End J-4 Dead Entl—►i, e—Load i m y � � Lea�tii141. 4—Dead End -►j live End o 1/2" Wire Rope - Live Entl � —Dead End �--Load r _ lR� Load --W �4 Dead End Live End > FIGURE 6-5 6.6. MAN -OUT -OF -HOLE ANCHORING 6.6.1. The Xerxes man -out -of -hole (MOH) strapping system is designed for use in installations where water is in the excavation and/or where personnel may not enter the hole because of site restraints. An MOH strapping system can be, but need not be, used in conjunction with Xerxes deadmen. 6.6.2. When using the MOH strapping system, the placement of components is critical. (See FIGURE 6-6.) See separate Xerxes document, Man -Out -of -Hole (MOH) Straps Instructions. FIGURE 6-6 6.7. ALTERNATE ANCHORING METHODS IN WET -HOLE INSTALLATIONS 6.7.1. In wet -hole installations, when Xerxes' preferred method of man -out -of -hole anchoring is not available, the following methods may be used. 6.7.1.1. With both methods, place the hold-down strap between the wire rope and the tank so that the wire rope is never in direct contact with the tank. 6.7.1.2. The H-shaped positioning clips around the strap are designed to accommodate the wire rope on top of the strap as shown in FIGURE 6-7 and FIGURE 6-8. 6.7.1.3. The following method is shown in FIGURE 6-7: • attach a wire rope to each end of each hold-down strap; • secure the termination of the wire rope (See SECTION 6.5. for suggested method.); • center each hold-down strap on each rib marked with the arrowhead symbols ►® ; • place the deadmen on top of the wire ropes on each side of the tank; • lower the deadmen to the bottom of the excavation; • take the slack out of each wire rope and splice the termination of the wire ropes on top of the tank (See SECTION 6.5.). 11
