The CM PiggyBack® Wedge Socket Clip is the only clip on the market specifically designed for securing the dead end of a wire rope on a wedge socket. Its revolutionary dual saddle design attaches quickly and easily to prevent crimping and damage to the live end of wire rope and eliminates the need for a short rope piece or loop on dead end. Properly secured dead end will not snag/foul and shear off at wedge socket. Available in 3/8 inch to 1-1/2 inch sizes. Hot dip galvanized with orange painted U-bolts and drop forged saddles.
PROPER USE OF PIGGYBACK WEDGE SOCKET CLIPS
- Dead end wire rope tail length should be at least 6 rope diameters, but not less than 6 inches beyond the wedge socket. See Figure 1.
- Apply U-bolt and first saddle on dead end rope and the second saddle on live end rope. Install nuts. See Figures 1 & 2.
- Position the dual saddle clip so that 3 to 4 inches of dead end rope remain beyond the clip. See Figures 1 & 2.
- Tighten nuts evenly. Alternate tightening each nut until reaching the required torque specified. See Figure 2.
- Check that clip does not pinch or clamp the live wire rope. Apply an initial test load equal to the loads expected in regular use. Be certain rope is secured properly in the wedge socket prior to any use.
- Inspect for proper rope alignment with wedge socket and retighten the nuts to the specified torque.
