People who often use slings understand that the slings series of wire rope products will appear after a period of time, "twist" phenomenon. The twisted wire rope cannot continue to be used, and must be immediately "put out" to restore the normal state of the wire rope. So what exactly caused the wire rope to twist together? Here is a detailed introduction for you.

In fact, the rope twisted together because the lifting height is not normal caused. Generally speaking, the steel wire rope is constantly wound and relaxed when lifting, and the pressure on the steel wire rope is also increasing, and the heavy object is eventually lifted. However, the lifting height of the wire rope should not be too high, otherwise the rotating internal force of the wire rope will gradually accumulate, and eventually cause the wire rope to rotate, and make the multiple strands of wire rope connected with it intertwine with each other, forming a "twist" state.

To sum up, if the wire rope you use is always kinked, you can appropriately reduce the lifting height and reinstall the wire rope. Do not rush to use already twisted wire rope, so as not to cause accidents.
