PREFORMED WIRE ROPE

 

PREFORMED WIRE ROPE

In a preformed wire rope, the individual wires in the strands, and strands composing the rope, are properly preshaped by preforming head before they are assembled into the finished rope. Preforming prevents the wire and strands from straightening, and leaves them relaxed in their normal positions in the rope. Preformed ropes have the following merits as compared with non-preformed ropes:

1. The flexibility is superior to non-preformed ropes, and during use wire ropes kink scarcely ever occurres.
2. Because preformed wire ropes have a great endurance to bending, a wire rope’s life will be longer.
3. Broken wire ends do not protrude to injure workmen’s hand, distort adjacent wires, or cause wear to sheaves and drums.
