TM5-3810-305-10SeizingWireRopeWhile there are numerous ways to cut wire rope,in every case certain precautions must be ob-served. Proper seizings are always applied onboth sides of the place where the cut is to bemade, In a wire rope, carelessly or inadequatelyseized, ends may become distorted and flattened,and the strands may loosen. Subsequently, whenthe rope is put to work, there may be an unevendistribution of loads to the strands. This condi-tion will significantly shorten the life of the rope.There are two widely accepted methods ofapplying seizing.1.2.Figure 4-29. Seizing Wire Rope - Method AMethod A: Lay one end of the seizing wire inthe groove between two strands; wrap theother end tightly in a close helix over aposition of the groove using a seizing iron (around bar 1/2 to 5/8 in. diameter by 18 in.long) (Figure 4-29). Both ends of the seizingwire should be twisted together tightly, andwith a finished appearance. Seizing widthsshould not be less than the rope diameter.Method B: The second of two accepted meth-ods for placing seizing on wire rope is illus-trated in Figure 4-30. The seizing itselfshould be a soft or annealed wire or strand.The seizing wire diameter and the length ofthe seize will depend on the diameter of thewire rope. But the length of the seizingshould never be less than the diameter of therope being seized. For preformed ropes, oneseizing on each side of the cut is normallysufficient. But for those that are not pre-formed, a minimum of two seizings is recom-mended (Figure 4-3 1). Seizings should bespaced six rope diameters apart.Figure 4-30.
