When the stainless steel wire rope is not properly maintained or the working load is too heavy, it is likely to be deformed, and some deformation will cause the strength of the wire rope to lose or even cannot be used normally. From the appearance, the deformation of stainless steel wire rope can be divided into four cases:
(1) Wave shape: The longitudinal axis of the stainless steel wire rope is in the shape of a spiral. When there is a wave shape, within the range of the length of the stainless steel wire rope not exceeding 25d, if d1>4d/3, the wire rope should be scrapped.
(2) kink: kink is a deformation caused by the stainless steel wire rope being tightened in a loop without being able to rotate around its axis. The result is an uneven lay length that causes extra wear and, in severe cases, the wire rope twists so that only a tiny fraction of the wire strength remains. Severely kinked stainless steel wire rope should be discarded immediately.
(3) Partially flattened: The partial flattening of the stainless steel wire rope is caused by a mechanical accident. In serious cases, the wire rope should be scrapped.
(4) Bending: Bending is the angular deformation of the stainless steel wire rope under external influences. The stainless steel wire rope with such deformation should be scrapped immediately.
