Cutting Wire Rope


CAUTION


The ends of type ZB wire rope must be ***fuse welded***. Failure to do so may cause the core to slip and/or the strands to loosen causing major wire rope damage.

When wire rope is to be cut, seizing should be placed on each side of the point where the wire rope is to be cut, to keep the strands in place. On preformed wire rope, one seizing on each side of the cut is enough. On non-preformed wire rope less than 7/8 in (23mm) diameter, two seizings are recommended. On non-preformed wire rope over 7/8 in (23mm) diameter, three seizings are recommended. Wire or strand must be used to seize non-preformed wire rope. Wire, strand, or heavy tape may be used to seize preformed wire rope.

Three Basic methods of cutting wire rope are recommended:

1. Abrasive cutting tools.
2. Shearing tools. (Wire cutters on small wire rope, a wire rope cutter, and hammer for larger wire ropes.)
3. Oxy/Acetylene fuel torch. A torch can be used to cut type ZB wire rope only. The heat will ***fuse weld*** the end, which is OK for type ZB , but not for other types which are not to be ***fuse welded***.
