TYPES OF SPLICES AVAILABLE
SUPERLOOP
AFGRIP
HAND SPLICE
TAPERED ENDS
• Useful for reeving steel wire rope through systems, for tirfors, for fitting wedge sockets, etc. • Eliminates seizing of steel rope
• Flemish Eye with tapered steel ferrule • Very efficient • Robust steel ferrule • Tapered steel ferrule to prevent snagging • No galvanic action between rope and ferrule • Recommended for fiery coal mines - does not have low temp spark.
• Turnback Eye with aluminium ferrule • Economic and efficient
• Standard Liverpool or Admiralty methods • Other special hand splices available • Cable laid and grommet slings available on request
CORRECT FITTING OF CROSBY ® WIRE ROPE CLIPS
Efficiency ratings for wire rope end terminations are based upon the catalogue breaking strength of wire rope. The efficiency rating of a properly prepared loop or thimble - eye termination of clip sizes 3mm through 22mm is 80%, and for sizes 25mm through 90mm is 90%. The number of clips shown (see Table 1) is based upon using RRL or RRL wire rope, 6 x 19 or 6 x 37 Class, FC or IWRC; IPS or XIP, XXIP. If Seale construction or similar large outer wire type construction in the 6 x 19 Class is to be used for sizes in 25mm and larger, add one additonal clip. If a pulley (sheave) is used for turning back the wire rope, add one additional clip. The number of clips shown also applies to rotation - resistant RRL wire rope, 8 x 19 Class, IPS, XIP, XXIP sizes 38mm and smaller; and to rotation-resistant RRL wire rope, 19 x 7 Class, IPS, CIP, CCIP sizes 45mm and smaller. For other classes of wire rope not mentioned above, we recommend contracting Shutterlock (Pty) Ltd at the address or telephone number on the back cover to ensure the desired efficiency rating. For elevator, personnel hoist, and scaffold applications, refer to ANSI A17.1 and ANSI A10.4. These standards do not recommend U-Bolt style wire rope clip terminations. The style wire rope termination used for any application is the obligation of the user.
3. When three or more clips are required, space additional clips equally between first two - take up rope slack - tighten nuts on each U-Bolt evenly, alternating from one nut to the other until reaching recom- mended torque.

1. Refer to the Table in following these instructions. Turn back specified amount of rope from thimble or loop. Apply first clip on base width from dead end of rope. Apply U-Bolt over dead end of wire rope - live end rests in saddle (Never saddle a dead horse). Tighten nuts evenly, alternate from one nut to the other until reaching the recommended torque.

2. When two clips are required, apply the second clip as near the loop or thimble as possible. Tighten nuts evenly, alternating until reaching the recommended torque. When more than two clips are required, supply the second clip as near the loop or thimble as possible, turn nuts on second clip firmly, but do not tighten. Proceed to Step 3.

If a greater number of clips are used than shown in the table, the amount of turn-back should be increased proportionately. * The tightening torque values shown are based upon the threads being clean, dry, and free of lubrication 85 - 90
