Piggy Back Rope Clips
|
|
|
An easy way to serue the dead end of a wire rope on a wedge socket.
||
|
Dual saddle design secures the dead end of a wire rope on a
wedge socket and procides the following benefits:
- Attaches quickly and easily.
- Eliminates need for short rope piece or loop on dead end.
- Properly secured dead end reduces possibility of snag/foul
and shear off at wedge socket.
- Available in 3/8" to 1 1/2" sizes.
- Dropped forge saddles.
- Application approved by OSHA.
- Hot dip galvanized, plus orange painted U-bolts.

*The tightening torque values shown are based upon the threads being clean,
dry and free of lubrication.

|
NOTE: Rotation resistant rope may require longer tail length.
|
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. Figure 1.
- Apply U-bolt and first saddle on dead end rope and the second saddle on live end
rope. Install nuts. Figures 1 & 2.
- Position the dual saddle clip so that 3 to 4 inches of dead end rope remain
beyond the clip. Figures 1 & 2.
- Tighten nuts evenly. Alternate tightening each nut until reaching the required
torque specified. 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 anyuse.
- Inspect for proper rope alignment with wedge socket and retighten the nuts to
the specified torque.
