Information

Wire Rope Clips can have a lot of usage.They are a simple fitting that can be easily used in the field or shop.

Sometimes called a u-bolt,u-bolt clip or cable clip,they can be used to join two wire rope ends together,make an eye for a pulling application,or to secure the loose end of a wire rope after a wedge socket(or other appropriate device)has been used to terminate a crane’s hook.

But using clips to create wire rope slings for overhead lifting is NOT one of their many uses.

--QUOTE--:

ASME B30.9 states that wire rope clips shall not be used to fabricate wire rope slings,except where the application of slings prevents the use of prefabricated slings.

ASME B30.9 also calls for any wire rope clip application to be designed by a qualified person.

ASME B30.9 states wire rope clips shall be drop-forged steel of single saddle(u-bolt)or double saddle clip.Malleable cast iron clips shall not be used.

ASME B30.26 contains specific instructions for the use of wire rope clips.

OSHA 1926.251(c)(4)(iii)states:Eyes in wire rope bridles,slings or bull wires shall not be formed by wire rope clips or knots.

--UNQUOTE--

If you are working in General Industry applications,it restricts the use of wire rope clips to form eyes.

Why these restrictions?

Wire rope clips diminish the working load limit of the wire rope to generally about 70-75%of its original strength.There are better and more efficient ways to fabricate slings for overhead lifting.

For situations where use of wire rope clips are approved,it’s important to remember the proper way to install the clips.Incorrect installation can reduce the working load limit by 40%or more.The easiest thing is to remember,“never saddle a dead horse.”

Wire Rope Clip Safety Notice!

Under the approved Code of Practice for Load Lifting&Rigging,slings assembled with wire rope clips are not to be used for lifting.

To comply with manufacturer’s specification the correct number of clips must be installed correctly andtightened to the correct torque using a torque wrench.The correct installation technique is shown below.
