What causes the wire rope to bend?
In the actual use of the process, the situation of wire rope bending is very common. For example, in the lifting process, if the crane boom movement is too large, it may lead to excessive bending of the wire rope; During the traction process, if the vehicle encounters a corner or slope change when driving, it will also cause the rope to bend. In addition, if the wire rope is in a state of tension for a long time, it will gradually bend. Different bending conditions of wire rope have different effects on its service life. In some mild bending cases, the service life of the wire rope may only be slightly reduced; However, in some serious bending cases, the wire rope may quickly fail, and even cut or break.
How to determine whether the wire rope can continue to use?
The influence of the bending of the wire rope on its service life is very complex, and can not be simply judged by naked eye observation or feel. Therefore, before judging whether the wire rope can continue to be used, we need to thoroughly test and evaluate it. First, we need to use a ruler or caliper and other tools to measure whether there is a significant change in the diameter of the wire rope. If the wire rope is compressed during bending, it will cause its diameter to become smaller. At this time, the bearing capacity of the wire rope will be significantly reduced, and it needs to be used with caution. Secondly, we need to observe the surface of the wire rope with the naked eye and feel. If the surface of the wire rope has obvious wear, scratching, cracks, etc., it means that it has been seriously damaged and needs to be replaced as soon as possible. In addition, if there is an obvious plastic deformation at the bend of the wire rope, it also indicates that it has been excessively bent and needs to be stopped.
Can the bent wire rope continue to be used?
For whether the bent wire rope can continue to be used, we need to evaluate it according to its bending situation. Generally speaking, only in the case of mild bending, the wire rope can continue to be used. However, if the bending of the wire rope is too serious, there has been obvious plastic deformation or surface damage, it needs to be replaced in time. In addition, we also need to evaluate according to the use of the wire rope environment and working requirements. If the wire rope is used in a harsh environment such as high temperature and corrosion, its bending fatigue life will be further reduced. At this time, even if the bending of the wire rope is not very serious, it needs to be used more carefully.
How to extend the service life of wire rope?
In order to extend the service life of the wire rope, we can start from the following aspects:
1. Use the wire rope correctly. In the use of wire rope, try to avoid its excessive bending, excessive stretching and other situations, reduce its force fatigue, can effectively extend its service life.
2. Test the wire rope regularly. Regular inspection of the wire rope can find its problems in time, and timely maintenance and replacement.
3. Strengthen maintenance management. During the use of the wire rope, it is necessary to regularly clean, grease and other maintenance work to ensure that its surface is smooth and lubricated, and reduce its force fatigue.
