1, the deformation of the corrugated wire rope is the longitudinal axis of the wire rope into a helical shape. This deformation does not necessarily result in any loss of strength, but if the deformation is serious, it will produce irregular transmission. Long time will cause wear and broken wire, the wave shape, in the wire rope length of not more than 25d within the range, if D1≥4D/3, the wire rope should be scrapped.
2, when the outer rope strands are disjointed or become more than the internal rope of the chief of the time will occur this deformation, cage-like distortion of wire rope should be scrapped immediately.
3. The rope stock is extruded to show that the wire rope is unbalanced, and the wire rope extrusion should be scrapped immediately. This deformation is a part of steel wire or steel wire rope on the side of the pulley groove on the back of the arch to form a ring, this deformation is often caused by impact load, if such a serious deformation, the wire rope should be scrapped.
4, the diameter of wire rope may occur locally increased, and can be affected by a considerable length of wire rope. The increase of rope diameter is usually related to the distortion of cord core, the inevitable result is that the outer rope strands are unbalanced and the positioning is incorrect.
5, rope diameter local serious increase of wire rope should be scrapped. Kink is because the wire rope into a ring in the unlikely rotation of its axis under the circumstances of the tension caused by a deformation, the result is the uneven twist in the uneven and caused by the extra wear, serious steel wire rope will be distorted, leaving only a minimum part of the wire rope strength.
