CORRECT METHOD
OF INSTALLING U-BOLT WIRE ROPE CLIPS
|
1.
Turn back specified length of rope from thimble and apply first clip
one saddle width from seized dead end. Tighten nuts
evenly to specified torque.
Important: Seat "live end" of wire rope (load carrying part) in saddle
and position U-bolt over "dead end". |
|
| 2.
Apply second clip close to the thimble without binding on it. Turn
on nuts firmly but do not tighten yet to recommended torque. |
|
3.
Apply all other clips, equally spaced between first two clips.
4. Apply light
tension and tighten all nuts evenly to specified torque. |
|
5. Recheck and re-tighten nuts after initial load. This load should
be at least equal to loads expected in general use. Wire
rope will stretch slightly causing a reduction in diameter
which will slacken the clips. Nuts must be checked at frequent intervals
for tightness to assure efficiency of termination. |
|
If the specified
number of clips are applied according to these instructions, they
will develop approximately 80% efficiency of right lay wire rope of
classes 6 x 19, 6 x 36, 7 x 19, 8 x 19, 19 x 7 and cable laid.
Add at least one
additional clip if thimble is not used or if clips are used on other
wire ropes than those mentioned above. Check with wire rope manufacturer
if in doubt. If more clips are used than specified, the amount of
wire rope to be turned back has to be increased proportionately.
