Deformation of the wire rope is mainly divided into which a few kinds

wavy

Wavy deformation is: the longitudinal axis of wire rope into spiral shape. This deformation may not cause any loss of intensity, but such as deformation, which will produce jitter caused by irregular transmission. After a long time can lead to wear and broken wires.

Wavy, within the scope of the wire rope length is not more than 25 d, if d1 4 d / 3 or more, the wire rope should be scrapped. Type d is the nominal diameter of wire rope; D1 is the diameter of the wire rope deformation after the envelope.

Cage distortion

This deformation is present in the steel core wire rope. When the outer strand occur or become disjointed than internal rope, the deformation occurs when come. The distortion of the cage wire rope should be discarded immediately.

Strand out

This kind of situation usually produce along with cage distortion. Strand wire rope imbalance be squeezed out. Strand of wire rope should be immediately discarded came out.

Wire extrusion

Such deformation is part of the steel wire or steel wire in wire rope beam carrying pulley groove on one side of the arch ring. This kind of deformation is often caused by impact load. If the deformation serious when, the wire rope should be scrapped.

Rope local increases

The possible local wire diameter increases, and can be affected quite a long rope. Rope increase is often associated with wire core distortion (such as in the special environment, fiber core inflation because of be affected with damp be affected with damp), its result is outer strand imbalance, caused by the location is not correct. Rope local severe increase of steel wire rope should be scrapped.

kink

Kink is due to the steel wire rope into a ring in the case of can't be around its axis of rotation is a deformation caused by tension. As a result, appear uneven length of lay more wear and tear, and serious when wire rope will produce distortion, so that leaves only a tiny fraction of the strength of steel wire rope. Severe kink in the wire rope should be discarded immediately.

Rope local decrease

The diameter of wire rope local often associated with the fracture of rope. Parts should be especially careful inspection on rope presence of this deformation. Rope local severe decrease of wire rope should be scrapped.

Some get squashed

Wire rope part get squashed due to mechanical failure. Seriously, the wire rope should be scrapped.

bending

Bending is caused by the wire rope in the outside world under the influence of Angle deformation. The deformation of the wire rope should be scrapped immediately.

Due to the effect of arc heat or cause damage

Wire rope through the special thermal effect its appearance appear to identify the color, the wire rope should be scrapped.
