Steel wire rope in this paper, the use of wire rope deformation for a long time

Wire rope in use after a long period of time, may be because of work load or has not been timely maintenance care, there is likely to deformation. So, exactly what kind of deformation of wire rope is damaged? How do we to judge? Super strength steel rope here to summarize for you.

1, the deformation of the wire rope wavy 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 will cause 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.

2, when the outer strand occur or become disjointed than internal rope, occurs when the deformation, come to the distortion of the cage wire rope should be scrapped immediately.

3, imbalance of out of the instructions for the rope strands wire rope, strand out of the wire rope should be scrapped immediately. 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 formation, which is often caused by impact load, serious when, if the deformation, steel wire rope should be scrapped.

Increases, the diameter of wire rope, there may be local, and can be affected quite a long rope. Rope is often associated with wire core distortion increase, its result is outer strand imbalance, caused by the positioning is not correct.

5, severe rope local increase of steel wire rope should be scrapped. 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, the result is more wear and tear, appear uneven lay length and serious when wire rope will produce distortion, so that leaves only a tiny fraction of the strength of steel wire rope.

Six, severe kink in the wire rope should be discarded immediately. Local decrease the diameter of wire rope is often associated with the fracture of rope core, should be especially careful inspection parts whether such deformation by rope.

7, local seriously reduce wire rope should be scrapped. Wire rope part get squashed is caused by mechanical accident, serious when, the wire rope should be scrapped.

8, bend is the Angle of the wire rope in the outside world under the influence of deformation, the deformation of the wire rope should be scrapped immediately. Caused by the action of heat or electric arc damage steel wire rope through the special thermal effect its appearance appear to identify the color, the wire rope should be scrapped.

By mastering these performance, everybody can be in daily operation to pay more attention to and timely found deformation phenomenon, timely repair and replacement, to avoid safety accident caused by damage of steel wire rope, add guarantee for work safety.
